Description

WEARABLE AIRFOIL

TECHNICAL FIELD

Disclosed herein is a wearable airfoil for reducing athlete air drag.

BACKGROUND OF THE INVENTION

Cyclists have attempted to improve cycling performance with rigid slipstream constructions, typically attached to the bicycle. These efforts typically focus on improving the aerodynamics of the bicycle frame and wheels or by placing Aerodynamic fairings around the cyclist. Ice Skaters have focused on reducing the garment skin friction, whereas little has been attempted for snow skiers. As important as these improvements have been, they do not address some of the primary sources of Aerodynamic Drag Forces on a cyclist, ice skater or skier. They are also cumbersome in many instances. The Aerodynamic Drag Forces are determined by the cyclist’s anatomy and posture during the pedal cycle with respect to the free stream. Likewise the skier’s or ice skater’s posture with respect to the free stream is of critical importance. The frontal area presented by the cyclist sportsman or sportswoman in the direction of motion is a parameter of key significance to the Aerodynamic Drag. Therefore, it is easy to see that the Aerodynamic Drag generated by the cyclist is many times larger than that generated by the bicycle frame and wheels. The problem is also more complex to analyze because of the complexities of the human body anatomy in the cycling postures. The same complexities of the human body anatomy in the skiing and skating postures are also paramount.

DETAILED DESCRIPTION

The current invention addresses various techniques to significantly reduce the Aerodynamic Drag Forces on a cyclist for various body types and postures through the pedal cycle.

Although the detailed description of examples of the invention is herein presented for a cycling application, the invention is also intended to be used by persons in many other applications. Among other applications for the current invention are snow Skiing (downhill, slalom & cross country), snow Boarding, ski jumping, Ice Skating, sky diving and others.

Aerodynamic principles are used to construct a cyclist garment that has a much more aerodynamically efficient shape than the current riding garments. The garment is comfortable, body conforming and significantly reduces the Drag generated by the Arms, Legs and Torso of the cyclist.

The garment is ergonomic and the various components of the garment can be assembled independently. The Leggings are interchangeable to the rider’s shorts and the Arms are interchangeable to the rider’s jersey.

In one version of the garment the cyclist can independently adjust the Aerodynamic efficiency generated by the garment Arms or Leg components.

Disclosed herein is a wearable airfoil for reducing air drag of a road or mountain cyclist, snow skier, ski jumper or ice skater, hence forward referred to as cyclist, skier or skater.

In one example, a garment is elastically tethered between two or more anchor locations on the garment that are positioned and arranged to form a transient airfoil surface on the garment. The airfoil changes in response to movement of the body of a person wearing the garment. The various airfoil (Torso, Arm & Leg) shapes and cross-sections change in response to movement of the body of a person wearing the garment through the pedal cycle, as well as through the skiing or ice skating motions..

In a further example, the wearable airfoil is tethered between a torso and an arm location.

In a further example, the wearable airfoil is tethered between a torso and a wrist location.

In a further example, the wearable airfoil is tethered between a shoulder and an arm location.

In a further example, the wearable airfoil is tethered between a shoulder and a wrist location.

In a further example, the wearable airfoil is tethered between a back of the ankle location and a back of the leg location. In a further example, the back of the leg location is an upper portion of the adductor longus.

In one further example, the wearable garment comprises airfoils tethered on the arms and airfoils tethered on the torso.

In one further example, the wearable garment comprises airfoils tethered for the arms and airfoils tethered for the torso and airfoils tethered for the legs.

In one example, a system two or more wearable garments combine to provide airfoils tethered for the arms or the torso and airfoils tethered for the legs.

In one example, a system two or more wearable garments combine to provide airfoils tethered for the arms and airfoils tethered for the torso and airfoils tethered for the legs. The current invention advances various techniques to significantly reduce the Aerodynamic Drag Forces on a cyclist, skier or ice skater for various body types and postures through the pedal cycle or skiing or ice skating body motions.

Aerodynamic principles are used to construct a cyclist (skier or skater) garment that has a much more Aerodynamically efficient shape than the current garments for these sports. The garment is comfortable, body conforming and significantly reduces the Drag generated by the Arms, Legs and Torso of the cyclist (skier or skater).

The garment is ergonomic and the various components of the garment can be assembled independently. The Leggings are interchangeable to the wearer’s shorts and the Arms are interchangeable to the wearer’s jersey.

In one version of the garment the cyclist (skier or skater) can independently adjust the Aerodynamic efficiency generated by the garment’s Arms and/or Leg Airfoils.

Fig. 1 is a right side view of a biker on a bicycle traversing from left to right, the right pedal in a zero degree (0°) position, with arms in a first posture position, with a long sleeve jersey. Fig. 1 shows a bicycle rider on a bicycle, illustrating the biker in a mid-pedal position. The two pedals are at approximately at the same horizontal elevation, with the right foot and pedal in the forward position, which will be called the zero degree (0 degree) position. The legs are bent at the knee. As illustrated, the right femur is roughly at -45 degrees and the right tibia is at approximately +80 degrees. The right knee angle is therefore approximately 65 degrees. This forms two sides of a virtual triangle. At moderate bike speeds, or equivalent headwind, for example fifteen to twenty miles per hour, the leg encounters an amount of air resistance. This resistance can be expressed in watts of power needed to overcome the headwind. For example, the resistance caused by the legs can represent thirty to forty percent of the total energy that the biker needs to expend to overcome aerodynamic drag, depending on the position of the torso. Three basic wearable garment components are introduced in Fig. 1. In this example, riding shorts 1 cover the pelvic and upper leg region of the biker. Jersey sleeves 2 cover the arms of the biker. A bodice 3, or jersey torso, cover the torso region of the biker. In a biker example, the garment components are made of a stretching, body-conforming material. In one example, the garment material is of a lycra-type material. Various types of materials will stretch in both perpendicular directions, enabling close conformance to the shape of the body and decreasing drag from otherwise floppy clothing.

Fig. 2 is a right side view of a biker on a bicycle traversing from left to right, the right pedal in a ninety degree (90°) position, with arms in the first posture position, with a long sleeve jersey. Fig, 2 shows a bicycle rider on a bicycle, illustrating the biker’s right foot in a up-pedal position, the left foot in a full down-pedal position. The right pedal is at approximately the plus ninety- degree (+90 degree) position. The right leg is fully bent at the knee. As illustrated, the right femur is roughly at -15 degrees and the right tibia is at approximately +50 degrees. The knee angle is therefore approximately 65 degrees. This forms two sides of a virtual acute triangle.

For convenience, Fig. 2 shows riding shorts 1 and jersey sleeves 2 and bodice 3.

Fig. 3 is a right side view of a biker on a bicycle traversing from left to right, the right pedal in a one hundred eighty degree (180°) position, with arms in the first posture position, with a long sleeve jersey. Fig. 3 shows a bicycle rider on a bicycle, illustrating the biker in a mid-pedal position. The two pedals are at approximately at the same horizontal elevation, with the right foot and pedal in the back position, which will be called the minus one hundred eighty degree (-180 degree) position. The legs are bent at the knee. As illustrated, the right femur is slightly lower than shown in Fig. 1, roughly at -50 degrees but the right tibia is at approximately +40 degrees. The right knee angle is therefore approximately 90 degrees. This forms two sides of a virtual triangle.

For convenience, Fig. 3 shows riding shorts 1 and jersey sleeves 2 and bodice 3. Fig. 4 is a right side view of a biker on a bicycle traversing from left to right, the right pedal in a two hundred seventy degree (270°) position, with arms in the first posture position, with a long sleeve jersey. Fig, 4 shows a bicycle rider on a bicycle, illustrating the biker’s right foot in a down-pedal position, the left foot in a full up-pedal position. The right pedal is at approximately the minus ninety-degree (-90 degree) position. The right leg is mostly fully extended at the knee. As illustrated, the right femur is roughly at -80 degrees and the right tibia is at approximately +85 degrees. The knee angle is therefore approximately 165 degrees. This forms two sides of a virtual acute triangle.

For convenience, Fig. 4 shows riding shorts 1 and jersey sleeves 2 and bodice 3.

Fig. 5 is a right side view of a biker on a bicycle traversing from left to right, the right pedal in the two hundred seventy degree (270°) position, with arms in a second posture position, with a long sleeve jersey. Fig. 5 shows a bicycle rider on a bicycle, illustrating the biker’s torso and arm position when the biker’s forearms are at rest at the handle bars. In this Fig. 5, the biker’s right leg is in the right pedal full down position, as shown in Fig. 4. In this posture, the torso is roughly at +63 degrees and the arms roughly at +130 degrees. The forearm is in a straight, extended position. At moderate bike speeds, or equivalent headwind, for example fifteen to twenty miles per hour, the torso and arms encounter an amount of air resistance. This resistance can be expressed in watts of power needed to overcome the headwind. For example, the resistance caused by the torso, in this posture, can represent 45 percent of the total energy that the biker needs to expend. The arms can represent roughly 25 percent of the total energy that the biker needs to expend to overcome aerodynamic drag.

For convenience, Fig. 5 shows riding shorts 1 and jersey sleeves 2 and bodice 3.

Riding Shorts & Airfoil Legging Assembly 100.

Leg airfoil assembly 100 substitutes for garment component riding shorts 1. As seen in this biker position, a garment portion of leg airfoil assembly 100 forms a web, an airfoil surface 102, between the gluttons and the ankle, behind the leg. In one example, the garment material of surface 102 is a stretchable, body-conforming material that allows for the stretching and suspension between the gluttons and ankle. In this extended position, the distance between the gluttons and ankle are at a mid-extended position, creating an aerodynamically efficient surface airfoil with low thickness to chord ratio.

As will be further described and illustrated, other features and structural components enable the formation of this changeable or transient airfoil as part of the wearable garment. In one example, an elastic band 104 is tethered between the gluttons and the ankle region, suspending surface 102 to form the airfoil. In one example, the elastic band 104 is cusped shaped and attached or integrated into the garment material that forms surface 102, thereby creating a trailing edge.

In one example, a front garment portion 103 of leg airfoil assembly 100 covers the front portion of the leg and attaches along a seam to the garment material of surface 102 that forms the transient airfoil. These structural features will be detailed further, herein.

For convenience, a dotted line G is shown to illustrate the positioning of the originally illustrated riding shorts 1.

Riding Jersey Sleeves & Airfoil Jersey Sleeves Assembly - Arm Airfoil Assembly 200.

Arm airfoil assembly 200 substitutes for garment component jersey sleeves 2. As seen in this biker position, the arms in a first posture position gripping the top of the handlebars, a garment portion of arm airfoil assembly 200 forms a web, an airfoil surface 201, between the upper torso (top of shoulder) and the wrist, and airfoil surface 202 under the arm and enclosing the armpit. In one example, the garment material of surface 201 is a stretchable, body-conforming material that allows for the stretching and suspension between the torso and wrist. In this first posture position, the distance between the torso and wrists are at a mid-extended position, creating a surface area airfoil faring under the arms. As will be further described and illustrated, other features and structural components enable the formation of this changeable or transient airfoil as part of the wearable garment. In one example, an elastic band 211 is tethered between the shoulder bodice 302 region and the wrist, suspending surface 201 over the arm, to form the arm airfoil. In one example, band 211 is bluff shaped and attached or integrated into the garment material that forms surface 201, thereby creating a leading edge. In one example, the bluff leading edge of band 211 is anchored in the shoulder region on one end (see, 209 in Fig. 17) and anchored in the wrist region (see, 210 in Fig. 17) on the other end. These structural features will be detailed further, herein.

In one example, the elastic band 211 is tethered from one end at the bodice shoulder region by a floating anchor and tethered from the other end in the wrist region by a fixed anchor. Anchoring to the garment, in one example, is accomplished by affixing the end of the elastic band to the wearable garment. In another example, the anchoring is accomplished using an additional supporting band. In another example, to accomplish anchoring, a member is disposed on the garment that distributes the tension forces of the elastic band, distributing them over an area of the garment. This reduces the concentration of the force to reduce opportunity for ripping the garment. These structural features will be detailed further, herein.

Riding Jersey Torso & Body Conforming Upper Body Torso Airfoil Assembly 300.

Torso airfoil assembly 300 substitutes for bodice garment component or torso 3. As will be further detailed, herein, in one example, a flat elastic band seam 304 joins the arm portions (201 and 202) to the bodice portions (301 and 302) of the garment. In one example a flat elastic band seam 303 joins the bodice portions 301 and 302. In one example, a detachable flat elastic band seam 304 runs from the bottom of the shoulder joint 308 around the shoulder.

Fig. 11 is a right side view of a biker on a bicycle traversing from left to right, showing placement of an example of the leg airfoil and placement of an example of the upper body torso airfoil and placement of an example of the upper body arm airfoil, with the right pedal in a ninety degree (90°) position, with arms in the first posture position, but in this example the jersey is shown in its short sleeve version.

Leg airfoil assembly 100 substitutes for garment component riding shorts 1. As seen in this biker position, leg airfoil assembly 100 forms a web, an airfoil surface 102, between the gluttons and the ankle. In this example, the so-formed changeable or transient airfoil 102 is shown in a relaxed position due to the contracted distance between the gluttons and ankle. The airfoil surface area is reduced and the stretchable, body-conforming material retracts to maintain an airfoil shape with a bluff leading edge around the chin of the leg (103) and a cusp trailing edge (104). This roughly symmetric airfoil shape has airfoil thickness to chord ratios that reduce the aerodynamic drag of the otherwise naked leg. The lower thickness to chord ratios lead to a significant reduction of the form drag on the leg by muting the vortex shedding around the leg.

In one example, in this position, elastic line 104 is in its least stretched condition along its length. Since the knee is most fully bent, the lycra of the garment of surface 102 pulls on the elastic line 104, anti-parallel to and along its arch length. In one example, the lycra of the garment of surface 102 pulls on the elastic line 104, orthogonal to its arch length. The tension drawn by surface 102 is approximately normal to the axes of the leg bones. This forms an airfoil shape for surface 102 behind the leg and also forms a catenary arc shape for the length of elastic line 104, the leg airfoil trailing edge.

Therefore, the illustrated elastic line 104 is shown at its minimum longitudinal tension and maximum “normal” tension, the normal tension vectors provided by the direction of the expandable threads of rear foil piece 102.

Arm airfoil assembly 200 substitutes for garment component jersey sleeves 2.

Torso airfoil assembly 300 substitutes for bodice garment component or torso 3. Fig. 12 is a right side view of a biker on a bicycle traversing from left to right, showing placement of an example of the leg airfoil and placement of an example of the upper body torso airfoil and placement of an example of the upper body arm airfoil, with the right pedal in a one hundred eighty degree (180°) position, with arms in the first posture position, with long sleeve jersey.

Leg airfoil assembly 100 substitutes for garment component riding shorts 1. As seen in this biker position, leg airfoil assembly 100 forms a web, an airfoil surface, between the gluttons and the ankle. In this example, the so-formed changeable or transient airfoil is shown in a relaxed position due to the contracted distance between the gluttons and ankle. Similar to the right leg forward, mid-pedal position, the airfoil surface area is reduced and the stretchable, body- conforming material retracts to maintain an airfoil shape with low thickness to chord ratios leading to significant reduction of the form aerodynamic drag on the leg by muting the vortex shedding around the leg.

Fig. 13 is a right side view of a biker on a bicycle traversing from left to right, showing placement of an example of the leg airfoil and placement of an example of the upper body torso airfoil and placement of an example of the upper body arm airfoil, with the right pedal in a two hundred seventy degree (270°) position, with arms in the first posture position, with short sleeve jersey.

Leg airfoil assembly 100 substitutes for garment component riding shorts 1. As seen in this biker position, leg airfoil assembly 100 forms a web, an airfoil surface, between the gluttons and the ankle. In this example, the so-formed changeable or transient airfoil is shown in a near fully- stretched position due to the extended distance between the gluttons and ankle. In this extended position, the distance between the gluttons and ankle are at a full-extended position, creating a relatively small surface area airfoil. The airfoil surface area is reduced and the stretchable, body- conforming material adapts with minimal resistance to the movement of the biker’s leg. It should be noted that even in this most extended posture of the leg the airfoil generated by the leggings (102 and 103) still have lower thickness to chord ratios than the naked leg thus generating less aerodynamic drag.

It should be noted, however, that when the right leg assumes one posture, the left leg is in a 180 degree opposite posture. For example, when the right leg is in the posture of Fig. 13, then the left leg is in the corresponding posture of the right leg of Fig. 11. Likewise, when the right leg is in the posture of Fig. 12, then the left leg is in the corresponding posture of the right leg of Fig. 10

Arm airfoil assembly 200 substitutes for garment component jersey sleeves 2.

Torso airfoil assembly 300 substitutes for bodice garment component or torso 3.

Fig. 14 is a right side view of a biker on a bicycle traversing from left to right, showing placement of an example of the leg airfoil surface 102 and placement of an example of the upper body torso airfoil and placement of an example of the upper body arm airfoil, with the right pedal in the two hundred seventy degree (270°) position, with arms in a second posture position, with long sleeve jersey. In this Fig. 14, the biker’s right leg is in the right pedal full down position, as used in Fig. 4. Fig. 14 shows the biker’s right leg in the position of Fig. 4 and Fig. 13, with an example of the leg airfoil assembly 100 of the present invention worn on the legs of the biker.

Fig. 14A is a right side view of a biker on a bicycle traversing from left to right, showing placement of an example of the leg airfoil surface 102 and placement of an example of the upper body torso airfoil, with the right pedal in the two hundred seventy degree (270°) position, with arms in a second posture position, with short sleeve jersey. Note that for the short sleeve jersey, in one example, there is no arm Airfoil. Fig. 15 is a 3-D perspective frontal view of a representation of a human body with arms extended horizontally, similar to Fig. 6, showing positioning and arrangement of frontal portions of an example of the leg airfoil assembly 100 and upper body airfoils, long sleeve airfoil assembly 200 and torso airfoil assembly 300.

Riding Shorts & Airfoil Legging Assembly 100.

An upper garment piece of the leg airfoil assembly 100 serves as riding leggings or shorts 101 and serves to structurally hold the rest of leg airfoil assembly 100 onto the bike rider. Shorts 101 are the upper portion of the airfoil leggings, the riding shorts.

In one example, a front garment portion 103 of leg airfoil assembly 100 covers the front portion of the leg and attaches along a seam to shorts 101 as well as the garment material of surface 102 that forms the transient airfoil. Front garment portion 103 forms the front portion of the airfoil leggings, an extension of the riding shorts. In one example, front garment portion 103 attaches on the front of the leg, above the knee. In one example, front garment portion 103 is shaped to cover the front of the leg, symmetric about the shin line, from above the ankle to the lower portion of the front of the shorts, above the knee. The front piece is shaped, positioned and arranged to be in contact with the front of the leg, from over the knee through the shin to above the ankle. In one example, if the leg is viewed as a cylinder with the shin line being zero degrees, the front piece is shaped, positioned, and arranged to cover, in one example, between -80 to +80 degrees of the front of the leg. In one example, if the leg is viewed as a cylinder with variable cross section diameter and the shin - femur line being at zero degrees, the front piece is shaped, positioned and arranged to cover, in one example, at an angle between -120 and -80 degrees to an angle between +120 and +80 degrees off of the shin - femur line at the front of the leg. In one example, a zipper seam line 107 joins the side and back of the upper portion of shorts 101 to the upper portion of the transient airfoil 102. In the example, the zipper seam line 107 joins the lower portion of the transient airfoil 102 to then lower portion of the front garment portion 103.

In one example, the angle location of the zipper seam line 107 with respect to the shin - femur line changes along the length of the leg over a range suitable to tripping the airfoil boundary layer.

In one example, a zipper seam line 108 joins the upper portion of the airfoil riding leggings, e.g., shorts 101 and the front portion of the airfoil riding leggings, e.g., front garment portion 103.

In one example, a flat elastic ankle band 109 is attached at or near the bottom of leg airfoil assembly 100. Ankle band 109 serves to assist in anchoring the bottom portion of leg airfoil assembly 100. This prevents the tension from band 104 (see Fig. 16) from pulling the legging up the leg.

In one example, the ankle band 109 is anchored to the foot by a sock like structure.

In one example, the ankle band 109 has an airfoil shape that extends behind the leg above the ankle. In one example ankle anchor 106 is disposed at the trailing edge of ankle band 109.

Ankle anchor point 106 illustrates one example of the termination point for the bottom of the cusp elastic line 104. In this example, it is shown above the ankle and behind the leg.

Riding Jersey Sleeves & Airfoil Jersey Sleeves Assembly - Arm Airfoil Assembly 200. In one example, the arm airfoil assembly 200 uses two portions of garment attached to the bodice portion of the garment, a front portion of airfoil jersey sleeves 201 and a back or rear of airfoil jersey sleeves (as illustrated in Fig. 16, components ante-arm portion 202 and fore-arm portion 203). A seam line 207 joins the front portion of airfoil jersey sleeves 201 with the upper ante- arm portion 202 of the airfoil jersey and with the fore-arm portion 203 of the airfoil jersey from the shoulder to the wrist.

If the arm is viewed as a cylinder with variable cross section diameter and the thumb - radius - humerus line being at zero degrees, the front portion of the airfoil jersey sleeves 201 is shaped, positioned and arranged to cover, in one example, at an angle between -120 and -80 degrees to an angle between +120 and +80 degrees off of the thumb - radius - humerus line at the front of the arm.

In one example, the angle location of the seam line 207 with respect to the thumb - radius - humerus line, changes along the length of the arm over a range suitable to tripping the airfoil boundary layer.

As illustrated in Fig. 14 and Fig. 15, an elastic band 211 stretches from the wrist to the shoulder and functions to form an airfoil leading edge. In one example, elastic band 211 has a bluff shape to create the airfoil leading edge. In one example, the airfoil bluff leading edge elastic band 211 is disposed from a shoulder anchor 209 to a fixed wrist anchor 210.

In one example, additional anchoring strength is obtained by affixing to the garment a flat elastic wristband component 212. The wrist end of airfoil band 211, anchor point 209, attaches to the wrist band 212. This prevents tension from band 211 from pulling the sleeve up the arm.

In one example, the wrist end of band 211 is anchored to the hand by a glove like structure. Riding Jersey Torso & Body Conforming Upper Body Torso Airfoil Assembly 300. The front side of garment component 302 of torso assembly 300 is shown. In one example, front side 302 attaches to the shorts 101 at the waist. Back or rear side 301 is shown in Fig. 16.

A flat elastic band seam at 303 runs along the sides of the body, joining the front side 302 to the back side 301 and anchoring components, which will be described further, herein.

In one example, a hip quick engage/release at 306 serves as a waist anchor between the body conforming airfoil jersey torso assembly 300 and the upper portion of airfoil leggings 101. The hip quick engage/release 306 is located on the side of the body, near the base of the joint of the front side garment component 302 and the back side garment component 301 (see Fig. 14).

A detachable flat elastic band seam 304 joins the bodice to the sleeves. Shoulder anchor point 209 is disposed at the band seam 304. A fixed torso anchor 308 (for the airfoil cusped trailing edge elastic band 204 shown in Fig. 16 and Fig. 16A) is disposed at the nadir of the arm opening of the bodice, at the band seam 304. The torso anchor 308 serves to anchor one end of the torso airfoil trailing edge that spans to the bottom of the arm at or near the elbow.

In a further example configuration, anchor point 209 is the shoulder anchor for an airfoil bluff leading edge elastic band 211. In one example, as illustrated, anchor 209 is disposed on sleeve garment portion 201 at or near the edge that joins with the bodice (elastic band 304). A bluff leading edge 211 spans from shoulder anchor point 209 to a fixed wrist anchor 210. In one example, a flat elastic wrist band component 212 wraps around the wrist, providing resistance in the longitudinal direction along the axis of the arm. This keeps the bluff edge 211 from pulling up the arm the wrist anchor 210. As can be appreciated, bluff elastic band 211 is composed so as to stretch and relax in response to the relative movements of the arm and torso to each other. This enables the airfoil to deploy and collapse as needed, without impairing the movements of the user and without causing significant additional effort to move on the part of the user. In one example, shoulder anchor 209 is an adjustable anchor, meaning that an adjusting member forms an anchor for one end of the bluff elastic band 211, at the shoulder end. This enables adjustment of the range of tension of the bluff elastic band 211 to suit the needs of the user. The desire or need for tension adjustment can be for any or all of a number of reasons. For example, more precise tension adjustment may be to better match a desired tension to the physical size of the wearer. In another example, the wearer or future research may find that a more specific tension is optimum than that provided if the bluff elastic band 211 were anchored at fixed anchor points at both ends. In another example, washing and wear and aging may affect the stretch of bluff elastic band 211. An adjustable or floating anchor enables future calibration of the tension of the bluff elastic band 211 for enhanced aerodynamic performance.

In can be appreciated that the specific examples described and/or illustrated herein are currently preferred examples. In further examples, it can be appreciated that the other edge elastic bands disclosed herein will have at least one floating or adjustable anchor. In further examples, a floating or adjustable anchor serves by adjusting the tension of the edge elastic band (by physically shortening or lengthening the length of the band between the anchors for a particular amount of tension applied). In other examples, the floating or adjustable anchor is disposed at a fixed location on the garment. In other examples, the floating or adjustable anchor is disposed with an adjustable location on the garment. In other examples, both ends are anchored with floating or adjustable anchors. In other examples, both ends are anchored with fixed anchors. In a range of other examples, applicant is disclosing all combinations of fixed-fixed, fixed- adjustable, floating- adjustable anchoring pairs and is disclosing all combinations of choices of type of floating or adjustable anchor (garment-fixed and garment-location-adjustable).

Fig. 15A is a partial 3-D perspective frontal view showing placement of an example of the upper body torso airfoil only, on a short sleeve jersey, without arm airfoil. In this example configuration, the sleeve above the elbow serves as the anchor location for the end of the torso airfoil. Flat elastic band seam at 303 along the side of the torso is also shown for reference. A zippered or otherwise detachable flat elastic band seam 304 runs along the armsyce, connecting the front of the torso garment portion 302 to the front portion of jersey arm garment portion 201 and connecting the back of the garment portion 301 (see Fig. 16) to the back portion of the jersey arm garment portion 202 (see Fig. 16). In this example, garment portion 201 is “short sleeve’, running to the elbow location on the arm. In one example, seam line 207 is disposed between the upper front portion of garment component 201 of the airfoil jersey sleeves and the ante-arm portion 202 of the airfoil jersey from the shoulder to the elbow.

In one example, a flat elastic elbow band 206 is attached above or near the elbow of the front portion of the airfoil jersey sleeves 201 and the back portion of the airfoil jersey sleeves 202 (see Fig. 16) of airfoil assembly 200. The elbow band 206 wraps around the arm. The elbow band 206 serves to assist in anchoring the distal portion of torso airfoil assembly 300.

Fig. 15B is a cross-section view of the arm portion of FIG. 14, showing positioning and arrangement of surfaces 201 and 202, airfoil cusped trailing edge elastic band or line 204, seam line 207, and elastic band 211.

Fig. 16 is a 3-D perspective rear view of a representation of a human body with arms extended horizontally, showing positioning and arrangement of the rear portions of an example of the leg and upper body (torso and arm) airfoils. Fig. 16 shows the biker in the position of Fig. 7 with an example of the airfoil pants 100 of the present invention worn on the legs of the biker. In this posture / position, elastic line 104 is in its most stretched condition along its length, anchored at its ends by anchors 105 and 106. In this posture, the airfoil is shaped and positioned in a least effective contribution to the drag reduction.

In one example, elastic line 104 is an airfoil cusped trailing edge elastic band. The rear foil piece 102 (also illustrated in Fig. 18) is shaped to envelope and drape behind the leg, hinging along an elastic line 104. In one example, elastic line 104 is attached to rear foil piece 102 along the length axis of piece 102, thereby draping behind the leg.

In one example, the airfoil legging portion 102 of legging assembly 100 is attached to biking shorts 101 along a seam line 107. In one example, this makes the airfoil field-detachable from the shorts. In one example, a seam line 107 runs from one side of the ankle anchor 106, up to an elevation proximate to leg anchor 105, running then across the back of the leg, and down the other side of the leg back to the other side of the ankle anchor 106. In one example, a zipper forms this seam line 107. The purpose of this seam line 107 is to enable detachment of the lower, airfoil portion 102 of the leggings 100 so that the user may selectively wear or take off the airfoil 102 without having to remove the riding shorts 101 portion of the riding shorts and airfoil legging assembly 100. In one example, the lengths of the outer edges of front piece 103 and rear airfoil piece 102 are joined together along seam 107 (as illustrated in Fig. 17 and Fig. 18).

In one example, the front piece 103 and the transient rear airfoil 102 are joined together along seam 107, disposed at a variable angle between -120 and -80 degrees to an angle between +120 and +80 degrees to the shin - femur line at the front of the leg.

Leg Anchor point 105 illustrates one example of the termination point for the top of elastic line 104. In this example, it is shown approximately two thirds of the length of the femur up from the knee, near the top of the femoris muscle, below the gluteus maximus, and on the back side of the leg. In one example, the leg point 105 is fixed or otherwise anchored to leggings 102. In one example, the leg point 105 is moveable over a fixed range to provide more comfort to the wearer. Rear foil piece leggings 102 add a streamlined leg positioning conforming shape to the leg. The surface of piece 102 streamlines the flow of air around the leg by cutting vortex shedding and frequency, thereby reducing the drag resistance.

In one example, a compression band 109 is attached to the bottom of airfoil leggings 102. In one example, compression band 109 is a flat elastic anchor band component of an ankle anchor assembly. Band 109 is configured to hold the bottom of legging 102 firm around the leg just above the ankle, to prevent the bottom of the legging 102 from riding up the leg.

Thus, the bottom of cusp elastic line 104 is anchored at or near the location of band 109 in the rear (180 degree relative to the front shin) of assembly 100. The top of cusp elastic line 104 is anchored at the top of leggings 102 in the rear, below shorts portion 101 (180 degree relative to the front of the thigh).

In one example, ankle anchor 109 is an adjustable anchor, meaning that an adjusting member forms an anchor for one end of the cusp elastic band 104, at the ankle end. This enables adjustment of the range of tension of the cusp elastic band 104 to suit the needs of the user. The desire or need for tension adjustment can be for any or all of a number of reasons. For example, more precise tension adjustment may be to better match a desired tension to the physical size of the wearer. In another example, the wearer or future research may find that a more specific tension is optimum than that provided if the cusp elastic band 104 were anchored at fixed anchor points at both ends. In another example, washing and wear and aging may affect the stretch of the cusp elastic band 104. An adjustable or floating anchor enables future calibration of the tension of the cusp elastic band 104 for enhanced aerodynamic performance.

Riding Jersey Sleeves & Airfoil Jersey Sleeves Assembly - Arm Airfoil Assembly 200

In one example, as illustrated in Fig. 14 and Fig. 16, a seam line 208 around the elbow region separates the ante-arm 202 and fore-arm 203 garment portions of the jersey sleeves. The jersey garment is separated into a front portion 201, and a back portion composed of the back ante-arm 202 and back fore-arm 203 components.

In one example, the arm airfoil assembly 200 uses two portions of garment attached to the bodice portion of the garment, a front portion of airfoil jersey sleeves 201 (as illustrated in Fig. 15) and the ante-arm portion of airfoil jersey sleeves 202 (as illustrated in Fig. 16). A seam line 207 joins the front portion of airfoil jersey sleeves 201 with the ante-arm back portion 202 of airfoil jersey sleeves. Seam line 207 also joins to the back fore-arm 203 portion of airfoil jersey sleeves.

In one example, the front portion of airfoil jersey sleeves 201 and the ante-arm portion 202 of airfoil jersey sleeves are joined together along seam 207, disposed along the arm at a variable angle between -120 and -80 degrees to an angle between +120 and +80 degrees with respect to the thumb - radius - humerus line.

In one example, as illustrated in Fig. 16, an elastic band 204 is disposed on the back of the arm, stretching from the armpit torso anchor 308 to the near the elbow at anchor 205. In one example, elastic band 204 is attached to the back ante-arm 202 portion of the jersey sleeves. In one example, elastic band 204 is an airfoil cusped trailing edge elastic band. One end of elastic band 204 is anchored at the base of the arm opening of the bodice (below the armpit) at torso anchor 308. The other end of elastic band 204 is anchored at or near the elbow, the elbow anchor 205. In one example, elbow anchor 205 is a floating anchor, as more fully described herein.

In one example, fixed torso anchor 308 serves to anchor a cusped leading edge elastic band 204 to the torso airfoil to assembly 300. Elbow anchor 205 and torso anchor 308 hold the cusped trailing edge elastic band 204 of the torso airfoil assembly. These anchor points hold the trailing edge as the arms and body move into and out of the various cycling positions. In one example, as illustrated in Fig. 15 and Fig. 16, the back of elastic wristband 212 is visible. The wristband 212 is used to provide additional anchoring of the bluff leading edge 211 of the arm airfoil.

Riding Jersey Torso & Body Conforming Upper Body Torso Airfoil Assembly 300

Back side 301 and front side 302 of the torso body conforming airfoil riding jersey, the bodice, are is shown attached along a detachable the flat elastic seam 303 and a waist anchor 306. They are further attached to the arms along a zippered or otherwise detachable seam 304 and torso anchor 308. The waistband 305 wraps around the waist and, in one example, includes a two- finger quick-release and engaging mechanism at the waist anchor, disposed on the sides of the body at the hip. In one example, waist anchor 306 is a two-finger quick-release mechanism that allows the user to quickly and easily detach the torso assembly 300 from the legging assembly 100. A flat elastic seam 303 is disposed vertically along the sides of the torso between the back side 301 and the front side 302 of the body conforming bodice and also to the fixed torso anchor 308. Thus, in one example, fixed anchor 308 is a relatively complex three-way juncture of elastic bands, which will be described in more detail, herein.

In should be appreciated, in all examples of anchors, that the anchors are configured, positioned, and arranged to spread the forces caused by the elastic bands across an area of the garment. This reduces the point-force pull on the garment, reducing the tendency for the garment to separate or be tom from the elastic band.

Fig. 16A is a partial 3-D perspective rear view showing placement of an example of the upper body torso airfoil only, on a short sleeve jersey, without arm airfoil. An elastic band 204 is disposed along the back of the arm, from the elbow to the torso. Seam 207 line forms the joint between two garment portions of the sleeves, namely front portion 201 and back ante-arm portion 202. Seam line 207 runs from the top of the shoulder portion of the arm to the elbow. In one example, elastic band 204 is a cusped trailing edge for the airfoil. The cusp elastic band is run between, and anchored to an elbow anchor 205 and a torso anchor 308. In one example, elbow anchor 205 is a floating anchor. In one example, torso anchor 308 is a fixed anchor.

In one example, an elastic band 206 wraps around the arm in the vicinity of the elbow, to provide additional anchoring support for the elbow anchor 205.

Fig. 16B is a cross-section view of the leg portion of FIG. 12, showing positioning and arrangement of surfaces 102 and 103, airfoil cusped trailing edge elastic band or line 104, and seam line 107.

Fig. 17 is a 3-D perspective frontal left side view of a representation of a standing human body with arms extended sideways, showing positioning and arrangement of frontal-side portions of an example of the leg and upper body (torso and arm) airfoils.

In one example, the lengths of the outer edges of front piece 103 and rear foil piece 102 are joined together along seam 107 (as illustrated in Fig. 17 and Fig. 18). In one example, seam 107 is field-detachable. In one example, seam 107 is a zippered seam, enabling removal of garment portions 102 and 103 from the rest of the shorts 101. In one example, a zipper seam line 108 traverses the front of the leggings 101, 103 to enable removal of the airfoil from the shorts.

In one example, the transient rear airfoil 102 is joined to the front piece 103 and the stretchable shorts 101 along seam 107, disposed at a variable angle between -120 and -80 degrees to an angle between +120 and +80 degrees with respect to the shin - femur line at the front of the leg.

For reference, elastic band 109 is shown wrapped around the ankle, becoming a part of an ankle anchor assembly. In one example, elastic band 109 is a flat elastic band, as further detailed, herein. From this perspective, as illustrated, the front portion 201 of the airfoil jersey sleeves are more fully shown. Again, seam line 207 joining front portion 201 to back fore-arm portion 202 runs along from the top of the shoulder to the end of the sleeve, here, at the wrist anchor 210 on the wristband 212. The bluff edge 211 of the airfoil is disposed on the sleeve midway along the front of the arm, from the wrist to the seam 304 connecting the bodice at the shoulder anchor 209. In one example, the leading edge 211 is an elastic band having an airfoil bluff leading edge. In one example, the leading edge elastic band 211 is anchored between the shoulder anchor 209 and wrist anchor 210. In one example, shoulder anchor 209 is a floating or adjustable anchor. In one example, anchor 209 is disposed at the intersection with bodice front portion 302. In one example, anchor 209 is connected to elastic band seam 304. Bodice back portion 301 is shown joined to front portion 302 by seam 303.

In one example, the front portion 201 is joined at the torso triple anchor 308. In one example, the torso triple-anchor 308 is a junction between a flat elastic band 303 and flat elastic band 304 and a cusp trailing edge 204 of the torso airfoil. In one example, flat elastic band 304 is zippered or otherwise detachable.

In one example, an elastic band 211 is tethered between the bodice 302 region and the wrist, suspending surface 201 over the arm, to form the airfoil. In one example, band 211 is bluff shaped and attached or integrated into the garment material that forms surface 201, thereby creating a bluff leading edge. In one example, the bluff leading edge of elastic band 211 is anchored in the shoulder region on one end 209 and anchored in the wrist region 210 on the other end.

Fig. 17A is a 3-D perspective frontal left side view showing placement of an example of the upper body torso airfoil only, on a short sleeve jersey, without arm airfoil. In the absence of an arm airfoil, the leading edge elastic band 211 does not exist on the front garment portion 201 of the short sleeve version of the airfoil jersey sleeves. Again, seam line 207 joining front portion 201 to upper back portion 202 runs along from the top of the shoulder to the end of the sleeve, here, the elbow region. In one example, a band 206 wraps around the elbow region of the arm, providing additional anchoring support for the cusped leading edge 204 of the torso airfoil, whose other end is anchored at fixed torso anchor 308. The torso anchor 308, being a triple juncture, rests at the arm opening (armpit) of the bodice and connects to seam 304. In one example, anchor 308 further connects to a flat elastic band Seam 303 joining the back 301 and the front 302 of the bodice. In one example, seam 304 allows field-detachment of the sleeves from the bodice, including detachment of the airfoil edge. In one example, seam 304 is zippered or otherwise detachable.

Fig. 17B is a cross-section view of the arm portion of FIG. 11, showing positioning and arrangement of surfaces 201 and 202, airfoil cusped trailing edge elastic band or line 204, and seam line 207.

Fig. 18 is a 3-D perspective rear right side view of a representation of a standing human body with arms extended sideways, showing positioning and arrangement of rear-side portions of an example of the leg and upper body (torso and arms) airfoils.

The major components exposed from this perspective include the rear portion of shorts 101, the rear garment portion of the airfoil leggings 102 (the riding shorts extension), the upper back garment portion of airfoil jersey sleeves 202, and the lower back garment portion of airfoil jersey sleeves 203.

From this perspective, the elastic edge band 104 for the leg airfoil is disposed on garment portion 102. Anchor 105 on garment portion 102 at the upper back of the leg holds one end of elastic edge band 104. The other end of elastic edge band 104 is held by anchor 106 on garment portion 102 at the ankle. A band 109 wraps around the ankle, attached to garment portion 102 and attached to anchor 106, keeps the leading edge 104 from pulling on the end of the leggings, keeping the leggings from riding up the leg. Garment portion 102 forms the airfoil and is shaped to envelope and drape behind the leg, hinging along elastic band 104. Ankle anchor point 106 illustrates one example of the termination point for the bottom of the cusp elastic line 104. In this example, it is shown above the ankle and behind the leg.

From this perspective, the torso airfoil edge 204 is visible. Torso airfoil edge 204 is disposed on the upper back garment portion 202 to span the airfoil in the armpit region. In one example, torso airfoil edge 204 is an elastic band that is attached and stretches and pulls garment portion 202 to form the trailing edge of the torso airfoil. In one example, torso airfoil edge 204 has a cusped shaped edge. In one example, anchor 205 is disposed on the back ante-arm garment portion 202 near the elbow edge at the elbow anchor. Triple juncture anchor 308 is disposed at the armpit intersection of seam 304 and seam 303. One end of airfoil edge 204 attaches at the torso anchor 308. The other end of airfoil edge 204 attaches at the elbow anchor 205. Thus, a changeable, transient airfoil surface is accomplished through a combination of type of garment material, positioning and arrangement of stretchable band disposed on the garment material, forming an edge, and position and arrangement of anchoring of the edge to the garment material. In one example, seam 304 is a zippered seam.

In one example, on the legs, a detachable seam 107 joins rear garment portion 102 to shorts 101 and to the front garment portion 103. Seam 107 runs in a horseshoe shape from the ankles up the upper legs below the gluteus and across the back of the legs and back down to the ankles. A detachable seam 108 above the knee runs across the front of the legs and joins front garment portion 103 to shorts 101. These seams enable the airfoil portion of the leggings (102, 103, 104) to be field-detachable from the shorts 101. In this way, the user is able to selectively add or remove the airfoil portion as desired during a riding journey. In one example, different styles of the lower leggings (102, 103, 104) are attachable, enabling different style or color combinations. In one example, differently engineered lower leggings (102, 103, 104) are attachable, enabling fi eld-change-out of airfoils with different performance characteristics. In one example, detachable seam 107 is a zippered seam. Fig. 18Ais a 3-D perspective rear right side view showing placement of an example of the upper body torso airfoil only, on a short sleeve jersey, without arm airfoil.

From this perspective, airfoil edge band 204 is shown disposed on the upper back garment portion 202 of a short sleeve jersey. A band 206 wraps around the arm in the region near the elbow, keeping the short sleeve from riding up the arm due to pulling by the airfoil edge band 204.

Fig. 19A is a 3-D perspective top view of a representation of a human right hand, a knuckle view, showing arrangement and placement of an example of wrist anchoring components for an upper arm airfoil. In some examples of present invention, it is desired to position the airfoil anchor closer to the wrist, or to provide greater anchoring for the airfoil than provided by the sleeve or the sleeve and wrist band, alone.

In one example, a wearable wrist anchor assembly is disclosed. The sleeve ends of front garment portion 201 and lower back garment portion 203 of the airfoil jersey sleeves are attached to a flat elastic wrist band member 212 that wraps around the wrist and attaches (in one example) at a seam 216 to other members 215 that anchor by wrapping around the palm and the valley between the thumb and forefinger. An edge seam 217 enables the fingers and knuckles to protrude, providing them freedom of movement. A fixed wrist anchor 210 is disposed on wristband member 212 on the wrist, beneath the thumb, and holds one end of a bluff leading edge airfoil elastic band 211. In one example, a hand glove member 215 extends from wristband member 212 to use the valley between the thumb and forefinger to further secure the anchoring position of wrist anchor 210. Opening edge 217 of hand glove extension member 215 provides an opening for the four fingers of the hand. Opening edge 214 of hand glove extension member 215 provides an opening for the thumb of the hand. Fig. 19B is a 3-D perspective side thumb view of a representation of a human right hand, a thumb / palm view, showing arrangement and placement of an example of wrist anchoring components for an upper arm airfoil.

From this perspective view, the positioning and area of wrist anchor 210 is more fully visible, positioned below the thumb, near the pulse area of the wrist. In one example, this wrist anchor 210 receives a tensioning adjusting member to enable selection of the tension placed on the airfoil elastic band 211.

In one example, a bluff shaped leading edge and elastic band or line 211 is disposed on the inner side of the garment material. In one example, a stretchable material band 211 is shaped in a convex outward shape and is disposed on, or otherwise attached or integrated into, front garment portion 201 of the airfoil jersey sleeves. In one example, the airfoil bluff shaped leading edge and elastic band 211 is disposed from a shoulder anchor 209 to a fixed wrist anchor 210. This forms a hump-like shape to the exterior garment surface, as the material 201 drapes over the internal anchor and bluff edge material. In this way, a bluff shaped leading edge is formed for the transient arm airfoil. In one example, the bluff leading edge is composed of a bluff shaped longitudinally stretchable elastic band 211 and bluff leading edge concave flexible ribs 111 as shown in Fig. 19F and Fig. 19G.

As can be appreciated, the leading edge bluff band design serves several purposes. One, the leading edge bluff directs the typically low speed airflow to smoothly go around the arm jersey airfoil surface. Two, the bluff leading edge responds continuously to the transient airfoil as it adapts to different body postures or arm positions of the user. Three the arm jersey airfoil works in conjunction with the torso airfoil a geometrically smooth fairing surface for the airflow around the shoulders, thereby reducing aerodynamic drag. In one example, within anchor 210 there is a cross-piece member, such as a pinion, and elastic band 211 assembly 2106. The cross-piece- pinion is perpendicular to the longitudinal direction of elastic band 211, at the terminal end of elastic band 211, serving to anchor and distribute the pulling forces of elastic band 211 to the rest of anchor 210 and, therefore, spreading the forces spatially to the garment portion 201. In one example, the cross-piece pinion in assembly 2106 is a cylinder.

In one example, two longitudinally stretchable elastic material seams 2112 connect the stretchable garment portion 201 to stretchable material surface 2111 (not shown in this view), as illustrated and further described in Fig. 19E and Fig. 19F.

Fig. 19D is a longitudinal cross sectional view (of cut 19D in Fig. 19C) of a terminal end of the elastic line to the surface of the airfoil garment material in the area of wrist anchor 210, forming a type I locking anchor for use as a long sleeve jersey wrist anchor. Fig. 19D illustrates a centerline cross sectional view of the anchor 210, with an example of a fixed type I locking anchor. In one example, cross-piece pinion of assembly 2106 is orthogonal to elastic band or line 211. In one example, the cross-piece pinion of assembly 2106 is a cylinder. In one example, elastic band or line 211 terminates in an eyelet, enabling elastic band or line 211 to be removed and reattached by sliding band or line 204 unto cylindrical cross-piece pinion of assembly 2106. In one example, the cross-piece pinion of assembly 2106, locks into the type I locking wrist anchor 210. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken.

In one example, this view illustrates the front portion if the jersey sleeves 201 disposed on wrist anchor 210. In this example, the view illustrates minor-axis cross sections of bluff leading edge concave flexible ribs 111, as illustrated further in Fig. 19F and Fig. 19 N, laid on the underside of the front portion if the jersey sleeves 20G. In one example, stretchable material surface 2111 lies parallel to the jersey sleeves 201 on the skin side of the wearer. Fig. 19E is a the skin view of attachment of a terminal end of the elastic line to the surface of the airfoil garment material in the area of wrist anchor 210, forming a type I locking anchor for use as a long sleeve jersey wrist anchor. As illustrated, skin side 20 G of jersey sleeves garment material is visible. Fig. 19E, illustrates in one example a skin view of the wrist type I locking anchor 210. In one example, elastic band 211 and bluff leading edge concave flexible ribs 111 (as shown in Fig. 19F and Fig. 19G) integrates with anchor 210 to distribute the stresses in the attachment to garment portion 201 and wrist band 212. In one example, the elastic line 211 of different longitudinal elastic characteristics is integrated with, and slides under, the bluff leading edge concave flexible ribs 111.

In one example, two longitudinally stretchable elastic material seams 2112 connect the stretchable garment portion 201 to stretchable material surface 2111, as further illustrated and described in Fig. 19F and Fig. 19G.

Tension Line Protection.

In one example, the airfoil edge elastic lines are located in an envelope to protect the wearer in case of breakage.

Fig. 19F is a cross sectional view of an example of a bluff shaped leading edge airfoil, elastic line and housing disposed on the inner side of the garment material for connecting the shoulder and wrist anchors. Fig. 19F in one example is a cross sectional view of an example of a bluff shaped leading edge airfoil, a major-axis cross section of a bluff leading edge concave flexible rib 111, and elastic line 211 and housing disposed on the inner side of the garment material for connecting the wrist and shoulder anchors. In one example, Fig. 19F illustrates a cross-section view of a bluff shaped leading edge of the arm airfoil between the shoulder and the wrist as well as the major-axis cross section of a bluff leading edge concave flexible rib 111 and elastic line or band 211 disposed on the inner side of the garment material. As illustrated, the front portion of garment portion 201 of the arm airfoil jersey sleeves drape over the bluff leading edge concave flexible rib 111 and longitudinally stretchable elastic band 211 slides and rests along the minor- axis of the bluff leading edge concave flexible rib 111.

In one example, two longitudinally stretchable elastic material seams 2112 connect the stretchable material surface 2111 of the garment portion 201 around and to envelop the bluff leading edge concave flexible rib 111 and the elastic line or band 211. In one example, seams 2112 of housing holding bluff leading edge concave flexible rib 111 and elastic line 211. This housing of bluff leading edge concave flexible rib 111 and elastic line 211 within the ‘moon shape’ volume define by the garment material 201 and the stretchable material 2111 imparts protection to the wearer if elastic line 211 breaks. In one example, stretchable material 2111 is the inner lining of housing holding.

Fig. 19G is a plane sectional view of an example of a bluff shaped leading edge airfoil (of cut 19G in Fig. 19F) rib and elastic line within the housing disposed on the inner side of the garment material for connecting the shoulder and wrist anchors. In one example, this view illustrates an ellipsoid shaped example of the bluff leading edge concave flexible rib 111 disposed on the inner side of garment portion 201. In one example, elastic band or line 211 rests and slides as it stretches or contracts over the bluff leading edge concave flexible rib 111. In a further example, other bluff leading edge concave flexible ribs 111 are laid regularly spaced along the bluff leading edge on the wrist shoulder line. In one example, the equally spaced bluff leading edge concave flexible ribs 111 are centered on their minor-axes along the leading edge wrist to shoulder line.

Thus, in one example, disclosed is an airfoil element adapted to be attached to a garment of a wearable airfoil for reducing a sportsman’s air drag having: an airfoil element attachable to the garment at least via one anchor element, whereas the airfoil element comprises a trailing edge, whereas the trailing edge being stretched between anchors by an elastic suspension line, and characterized in that the suspension line is accommodated within a casing extending along the trailing edge. In further example, the casing is formed by an envelope elastic material, particularly the elastic fabric material of the airfoil element.

In further example of either of the two foregoing examples, the casing is formed by a tube element being elastically stretchable in its longitudinal direction and being fastened particularly stitched and/or glued and/or welded to the trailing edge of the airfoil element.

In further example of either of the three foregoing examples, the suspension line is adapted to slide within the casing and is fixed at distinct and distant locations along the longitudinal direction of the suspension line.

In further example of either of the four foregoing examples, each free end of the suspension line protrudes from a corresponding free end of the casing to be freely accessible for anchoring to the garment.

In further example of either of the five foregoing examples, the free ends of the suspension line are formed in size such that the free ends of the suspension line are prevented from slipping into the casing.

Thus, in one example, disclosed is an airfoil element adapted to be attached to a garment of a wearable airfoil for reducing a sportsman’s air drag having: an airfoil element attachable to the garment at least via one anchor element, whereas the airfoil element comprises a leading edge, whereas the leading edge being stretched between anchors by an elastic suspension line, and characterized in that the suspension line is supported by cross rib elements and the suspension line is accommodated within a casing extending along the leading edge.

In further example, the casing is formed by an envelope elastic material, particularly the elastic fabric material of the airfoil element. In further example of either of the two foregoing examples, the casing is formed by a tube element being elastically stretchable in its longitudinal direction and being fastened particularly stitched and/or glued and/or welded to the leading edge of the airfoil element.

Replaceable Airfoil Tension Lines.

In one example, the airfoil edge elastic lines are designed to easily engage and replace at the anchor attachment points.

Fig. 20A is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey right hand side shoulder anchor 210.

In one example, this is a front view of the garment in the area of the shoulder anchor 210, as seen from exterior side of the garment as exposed to the air. In one example, elastic band 211 terminates into the airfoil cusp shaped trailing edge and is attached to the garment material, for example, garment portion 202. In this example, the tensional pull load from elastic band 211 is distributed away from a point force to a surface force, relieving excess stress on the garment material and reducing tendency to tear from the repeated pulling force. In one example, garment material 202 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, shoulder anchor 210 integrates with an elastic band 211. Elastic band 211 is a longitudinally stretched within a ‘triangular’ volume defined by the garment material 202 on two sides and a portion of the stretchable material 2111 disposed on the inner side of the cusp airfoil trailing edge and connected to the garment material 202 at seams 2112. The outward apex edge of elastic band 211 pushes on garment portion 202 from underneath, forming an apex shape to an outer surface portion 2114 of the garment 202. Within the anchor 210 there is a cross-piece pinion and elastic band 211 assembly 2106. The cross-piece-pinion is perpendicular to the longitudinal direction of elastic band 211, at the terminal end of elastic band 211, serving to anchor and distribute the pulling forces of elastic band 211 to the rest of anchor 210 and, therefore, spreading the forces spatially to the garment portion 202. In one example, the cross-piece pinion in assembly 2106 is a cylinder.

Fig. 20B is a longitudinal cross sectional view (of cut 20B in Fig. 20A) of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey right hand side shoulder anchor 210.

In one example, illustrated is is a shoulder anchor axial cross sectional of the cusp trailing edge and shoulder anchor as attached to garment. In one example, garment material 202 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, cross-piece pinion of assembly 2106 is orthogonal to elastic band or line 211. In one example, cross-piece pinion of assembly 2106 is a cylinder. In one example, elastic band or line 211 terminates in an eyelet, enabling elastic band or line 211 to be removed and reattached by sliding band or line 211 unto cylindrical cross-piece pinion of assembly 2106. In one example, the cross-piece pinion of assembly 2106, locks into the type I locking shoulder anchor 210. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken.

In one example, this view illustrates the front portion if the jersey sleeves 201 disposed on wrist anchor 210. In this example, the view illustrates minor-axis cross sections of bluff leading edge concave flexible ribs 111, as illustrated further in Fig. 19F and Fig. 19G, laid on the underside of the front portion if the jersey sleeves 20G. In one example, stretchable material surface 2111 lies parallel to the jersey sleeves 201 on the skin side of the wearer.

Fig. 20C is a longitudinal cross sectional view (of cut 20C in Fig. 20A) of the Detachable Flat elastic band on the right long sleeve jersey, forming a zippered attachment between the right long sleeve jersey and torso components of the jersey. In one example, the flat elastic band 304 is disposed under the right side edge of the arm jersey sleeves around the armsyce of the sleeve front garment portion 201 and the sleeve back garment portion 202.

In one example, the flat elastic band 304 runs around the armsyce and is lined on the edge with a zippered attachment 3045. In one example, zippered attachment 3045 is a zippered seam line between torso front garment component 302 torso back garment component 301 to the back ante- arm jersey sleeves component 202. In one example, the zippered attachment 3045 connects to the jersey torso front garment portion 302 and the jersey torso back garment portion 301. In one example, the zippered attachment 3045 of flat elastic band 304 connects the jersey torso front side 302 and the jersey back side 301 to the arm jersey sleeves front side 201 and the arm jersey sleeves back side 202 around the armsyce. In one example, the flat elastic band 304 runs around the armsyce and connects the jersey torso front side 302 to the arm jersey sleeves front side 201 at around the shoulder at a shoulder type I locking anchor 210.

Fig. 20D is an orthogonal cross sectional view (of cut 20D in Fig. 20A) of the Flat elastic band on the right long sleeve jersey, forming a zippered attachment between the right long sleeve jersey and torso components of the jersey. In one example, the flat elastic band 304 is disposed under the right side edge of the arm jersey sleeves around the armsyce of the sleeve front garment portion 201 and the sleeve back garment portion 202. In one example, the flat elastic band 304 runs around the armsyce and is lined with a zippered attachment 3045.

Fig. 20E is an orthogonal shoulder anchor cross sectional view (of cut 20E in Fig. 20A) of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey right hand side shoulder anchor and connection to the armsyce flat elastic band 304. In one example, cross-piece pinion of assembly 2106 is orthogonal to the terminal end of elastic band or line 211. In one example, cross-piece pinion of assembly 2106 is a cylinder. In one example, elastic band or line 211 terminates in an eyelet, enabling elastic band or line 211 to be removed and reattached by sliding band or line 211 unto cylindrical cross-piece pinion of assembly 2106. In one example, the cross-piece pinion of assembly 2106, locks into the type I locking shoulder anchor 210. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken.

Fig. 20F is the skin view of attachment of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey right hand side shoulder anchor. As illustrated, shown is skin side 201’ of the material portion of airfoil jersey sleeves 201. As illustrated, shown is skin side 302’ of the garment component 302 of torso assembly 300. Fig. 21C, in one example, is an underneath view of the garment in the shoulder area of anchor 210, as seen from interior side of the garment, the side touching the skin. As illustrated, the cusp apex shapes the outer surface of the garment into the desired trailing edge shape.

In one example, Fig. 20F illustrates the skin view of the garment in the area of the shoulder anchor 210, as seen from the interior side of the garment as exposed to the skin. In one example, elastic band 211 which terminates into the airfoil cusp shaped trailing edge is covered by a stretchable garment material 2111 and is attached to the garment material portion 202 at the seams 2112.

Fig. 20G is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey left hand side shoulder anchor 210. In one example, this is a front view of the garment in the area of the shoulder anchor 210, as seen from exterior side of the garment 201 as exposed to the air. In one example, elastic band 211 terminates into the airfoil cusp shaped trailing edge and is attached to the garment material, for example, garment portion 202. In this example, the tensional pull load from elastic band 211 is distributed away from a point force to a surface force, relieving excess stress on the garment material and reducing tendency to tear from the repeated pulling force. In one example, garment material 202 is the upper back portion or ante- arm of the airfoil jersey sleeves. In one example, shoulder anchor 210 integrates with an elastic band 211. Elastic band 211 is a longitudinally stretched within a ‘triangular’ volume defined by the garment material 202 on two sides and a portion of the stretchable material 2111 disposed on the inner side of the cusp airfoil trailing edge and connected to the garment material 202 at seams 2112. The outward apex edge of elastic band 211 pushes on garment portion 202 from underneath, forming an apex shape to an outer surface portion 2114 of the garment 202. Within the anchor 210 there is a cross-piece pinion and elastic band 211 assembly 2106. The cross- piece-pinion is perpendicular to the longitudinal direction of elastic band 211, at the terminal end of elastic band 211, serving to anchor and distribute the pulling forces of elastic band 211 to the rest of anchor 210 and, therefore, spreading the forces spatially to the garment portion 202. In one example, the cross-piece pinion in assembly 2106 is a cylinder.

Fig. 20H is an orthogonal shoulder anchor cross sectional view (of cut 20H in Fig. 20G) of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey left hand side shoulder anchor and connection to the armsyce flat elastic band 304. In one example, cross-piece pinion of assembly 2106 is orthogonal to the terminal end of elastic band or line 211. In one example, cross-piece pinion of assembly 2106 is a cylinder. In one example, elastic band or line 211 terminates in an eyelet, enabling elastic band or line 211 to be removed and reattached by sliding band or line 211 unto cylindrical cross-piece pinion of assembly 2106. In one example, the cross-piece pinion of assembly 2106, locks into the type I locking shoulder anchor 210. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken.

Fig. 201 is a longitudinal cross sectional view (of cut 201 in Fig. 20G) of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey left hand side shoulder anchor 210.

In one example, illustrated is a shoulder anchor axial cross sectional of the cusp trailing edge and shoulder anchor as attached to garment. In one example, garment material 202 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, cross-piece pinion of assembly 2106 is orthogonal to elastic band or line 211. In one example, cross-piece pinion of assembly 2106 is a cylinder.

Thus, a user can replace a line or band that has lost its tension and/or has broken.

In one example, this view illustrates the front portion if the jersey sleeves 201 disposed on wrist anchor 210. In this example, the view illustrates minor-axis cross sections of bluff leading edge concave flexible ribs 111, as illustrated further in Fig. 19M and Fig. 19 N, laid on the underside of the front portion if the jersey sleeves 20 G. In one example, stretchable material surface 2111 lies parallel to the jersey sleeves 201 on the skin side of the wearer. Fig. 20J is the skin view of attachment of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as a long sleeve jersey left hand side shoulder anchor. Fig. 21C is one example is an underneath view of the garment in the shoulder area of anchor 210, as seen from interior side of the garment, the side touching the skin. As illustrated, the cusp apex shapes the outer surface of the garment into the desired trailing edge shape.

In one example, Fig. 2 IF illustrates the skin view of the garment in the area of the shoulder anchor 210, as seen from the interior side of the garment as exposed to the skin. In one example, elastic band 211 which terminates into the airfoil cusp shaped trailing edge is covered by a stretchable garment material 2111 and is attached to the garment material portion 202 at the seams 2112.

Thus, in one example, disclosed is an airfoil element adapted to be attached to a garment of a wearable airfoil for reducing a sportsman’s air drag having an airfoil element attachable to the garment at least via one anchor element, where the airfoil element comprising at least one elastic suspension line is adapted to be stretched between anchor locations, and where the free ends of the suspension line are adapted to be engaged to and disengaged from the anchor locations by hand without the need of additional tools.

In further example, the means for tool-less engagement and disengagement of the free ends are at least one out of the group including: clips, snap fasteners, loops for engagement with a hooklike anchor or a pin-like anchor, Velcro fasteners.

Adjustable Anchors.

Fig. 20K is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type II adjustable anchor for use as a long sleeve jersey shoulder anchor (or wrist) anchor. Fig. 20K illustrates an example of an air view of example of a shoulder adjustable anchor 209. In one example, the airfoil bluff shaped leading edge and elastic band 211 is disposed from a shoulder anchor 209 to a fixed wrist anchor 210. A cap or knob 2095 is disposed on the axis 2096 of anchor 209. Cap or knob 2095 serves as a knob for adjustment of the tension of elastic line 211. Elastic line 211 serves to taunt or loosen the suspension of the transient airfoil that is disposed between the two anchors. A pin 2118 acts as a guide to assist guiding the elastic band 211 to and from about a spool 2097 (as shown in Fig, 20L). By turning cap or knob 2095, elastic line 211 is wound or unwound about axis 2096 and thus wound or unwound about spool 2097. In one example, detents (not illustrated) or protrusions hold cap or knob 2095 in place by manually rotating knob 2095 to a user preferred setting. In one example, knob 2095 houses a small motor (not illustrated) electronically controlled through a WIFI interface, to a user preferred user setting. In one example, a clicking sound from the detents or protrusions assist the user in knowing the amount of the cap or knob 2095 has been rotated.

In one example, two longitudinally stretchable elastic material seams 2112 connect the stretchable garment portion 201 to stretchable material surface 2111 (not shown in this view), as illustrated and further described in Fig. 20M, Fig. 19F and Fig. 19G.

Fig. 20L is a longitudinal cross sectional view (of cut 20L in Fig. 20K) of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type II adjustable anchor for use as a long sleeve jersey shoulder anchor (or wrist) anchor. Fig. 20L illustrates 2QE a centerline cross sectional view of an example of a shoulder adjustable anchor. In this side view, spool 2097 is shown with elastic band 211 winding about axis 2096. In one example, detents (not illustrated) or protrusions hold cap or knob 2095 in place by manually rotating knob 2095 to a user preferred setting. In one example, knob 2095 houses a small motor (not illustrated) electronically controlled through a WIFI interface, or equivalent, to a user preferred user setting. In one example, a clicking sound from the detents or protrusions assist the user in knowing the amount of the cap or knob 2095 has been rotated. In one example, this view illustrates the front portion if the jersey sleeves 201 are disposed on wrist anchor 210. In this example, the view illustrates minor-axis cross sections of bluff leading edge concave flexible ribs 111, as illustrated further in Fig. 19F and Fig. 19G, laid on the underside of the front portion of the jersey sleeves 20 G. In one example, stretchable material surface 2111 lies parallel to the jersey sleeves 201 on the skin side of the wearer.

Fig. 20M is a skin view of attachment of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type II adjustable anchor for use as a long sleeve jersey shoulder anchor or wrist anchor. Fig. 20M illustrates, in one example, a skin view of example of the shoulder (or wrist) type II adjustable anchor 209. Spool 2097 is on the underside 20G surface of jersey arm garment portion 201. In one example, elastic band 211 integrates with anchor 209 to distribute the stresses in the attachment to garment portion 201. In one example, the elastic line of different longitudinal elastic characteristics is integrated through a hole on the bluff airfoil leading edge elastic foam material.

Thus, in one example, disclosed is a wearable airfoil having: a garment, the garment including at least an anchor unit adapted to receive a fastening means of an airfoil element, and characterized in that the anchor unit includes adjusting means capable to adjust a tension of an edge of the airfoil element by at least controlling an effective length of the edge.

In further example, the adjusting means include at least one of the group including: a wrap body capable to wind and unwind an elastic line thereby stretching and releasing the edge of the airfoil element, a clamping means adapted to clamp the elastic line at certain positions, a slide element adapted to connected to the elastic line and movable with respect to the garment in order to stretch or release the elastic line. In further example of either of the two foregoing examples, the adjusting means is drivable manually or by an actuator means.

In further example of the three foregoing examples, the adjusting means is drivable in a linear or circular manner or in a combined manner.

In further example of the four foregoing examples, the adjusting means are remotely controlled, particularly by Wi-Fi, Bluetooth or near field communication technology.

In further example of the five foregoing examples, the anchor unit is located in a shoulder region, a wrist region, a hip region, an ankle region, a torso region, a leg region or an arm region of the wearable airfoil.

In further example of the six foregoing examples, the adjusting means is adapted to be capable of: controlling an aerodynamic efficiency of the airfoil element, changing a chord to thickness ratio of the airfoil element, adjusting the effective length of the chord of the airfoil element.

In further example of the seven foregoing examples, the edge of the airfoil element is a leading edge, particularly an arm bluff leading edge. In further example of those seven foregoing examples, the edge of the airfoil element is a trailing edge, particularly a leg or torso trailing edge.

Fig. 21 A is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type I locking anchor for use as an elbow anchor. In one example, this is a front view of the garment in the area of the elbow anchor 205, as seen from exterior side of the garment as exposed to the air. In one example, elastic band 204 terminates into the airfoil cusp shaped trailing edge and is attached to the garment material, for example, garment portion 202. In this example, the tensional pull load from elastic band 204 is distributed away from a point force to a surface force, relieving excess stress on the garment material and reducing tendency to tear from the repeated pulling force. In one example, garment material 202 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, elbow anchor 205 integrates with an elastic band 204. Elastic band 204 is longitudinally stretched within a ‘triangular’ volume defined by the garment material 202 on two sides and a portion of the stretchable material 2041 disposed on the inner side of the cusp airfoil trailing edge and connected to the garment material 202 at seams 2042. The outward apex edge of elastic band 204 pushes on garment portion 202 from underneath, forming an apex shape, the cusp shaped airfoil trailing edge of the garment 202. Within the anchor 205 there is a cross-piece pinion and elastic band 204 assembly 2056. The cross-piece-pinion is perpendicular to the longitudinal direction of elastic band 204, at the terminal end of elastic band 204, serving to anchor and distribute the pulling forces of elastic band 204 to the rest of anchor 205 and, therefore, spreading the forces spatially to the garment portion 202. In one example, the cross piece pinion in assembly 2056 is a cylinder.

Fig. 21B is a longitudinal cross sectional view (of cut 21B in Fig. 21A) of attachment of a terminal end of the elastic band or line 204 to the surface of the airfoil garment material 202, forming a type I locking anchor for use as an elbow anchor 205. In one example, illustrated in an elbow anchor axial cross sectional of the cusp trailing edge and elbow anchor as attached to garment. As illustrated, pinion 2056 resides underneath garment portion 202 and, in one example, is not accessible from the outside garment side. In one example, pinion 2056 is accessible from the skin side 202’. In one example, garment material 202 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, cross-piece pinion of assembly 2056 is orthogonal to elastic band or line 204. In one example, the cross-piece pinion of assembly 2056 is a cylinder. In one example, elastic band or line 204 terminates in an eyelet, enabling elastic band or line 204 to be removed and reattached by sliding band or line 204 unto cylindrical cross-piece pinion of assembly 2056. In one example, the cross-piece pinion of assembly 2056, locks into the type I locking elbow anchor 205. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken. In one example, stretchable material surface 2041 lies parallel to garment material portion 202 on the skin side of the wearer.

Fig. 21C is the skin view of the attachment of a terminal end of the cusped elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as an elbow anchor. Fig. 21C in one example is an underneath view of the garment in the elbow area of the anchor 205, as seen from interior side of the garment, the side touching the skin. As illustrated, the cusp apex shapes the outer surface of the garment into the desired trailing edge shape.

In one example, Fig. 21C illustrates the skin view of the garment in the area of the elbow anchor 205, as seen from the interior side of the garment as exposed to the skin. In one example, elastic band 204, which generates the cusp shape of the leg airfoil trailing edge, 2044 is covered on the skin side by a stretchable garment material 2041 and is attached to the garment material portion 202 at the seams 2042 as illustrated in Fig. 2 ID.

Fig. 2 ID is a cross-section view of an example of a cusped shaped trailing edge airfoil elastic line disposed on the inner side of the garment material. Fig. 2 ID in one example is a cross sectional view of an example of a cusped shaped trailing edge airfoil elastic line and housing disposed on the inner side of the garment material for connecting the elbow and torso anchors. In one example, Fig. 2 ID illustrates a cross-section view of a cusped shaped trailing edge of the torso airfoil as well as elastic line or band 204 disposed on the inner side of the garment material. In examples, the cusped shaped trailing edge elastic line or band is used for either or both the torso airfoil and/or the leg airfoil. As illustrated, an upper back portion (ante-arm) of garment portion 202 of the airfoil jersey sleeves drape over the longitudinally stretchable elastic band 204. This forms the cusp-shape of the trailing edge of the torso airfoil at the elbow. In one example, the garment material 202 and the elastic band 204 form two sides of a safety housing for elastic band 204. The third side of the safety housing for elastic band 204 is defined by the stretchable material 2041 at seams 2042 to garment material 202. The two longitudinally stretchable elastic material seams 2042 connect the stretchable material surface 2041 of the garment portion 202 around and to envelop the elastic line or band 204. This housing of elastic line 204 within the ‘triangular’ volume define by the garment material 202 and the stretchable material 2041 imparts protection to the wearer if elastic line 204 breaks.

Type Anchors.

Fig. 22A is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type II locking anchor 308 for use as a left hand side torso anchor 308. This anchor joins the end of one elastic band 204 a triple juncture to torso flat elastic band 303 and shoulder flat elastic band 304. The juncture to the shoulder elastic band 304, which goes around the armsyce, occurs at two points on torso anchor 308.

In one example jersey sleeves back garment portion 202, which drapes over elastic line 204 to form a cusp shape trailing edge, connects at shoulder elastic band 304. In one example the shoulder elastic band 304 connects to the jersey front garment portion 302 on one side and the jersey back garment portion 301 on the other side.

In one example, the type II locking anchor 308 is placed on the intersection seam elastic band 303 and the two ends of the shoulder seam elastic band 304 that runs around the armcyse. In one example shoulder elastic band 304 connects the back torso garment portion 301 and the front torso garment portion 302 to garment portion 202 of ante-arm (long or short) jersey sleeves.

In one example the shoulder seam elastic band 304 and torso anchor 308 are zippered and detachable from the jersey. In one example the zippered edge 3045 connects the jersey torso garment portions 301 and 302 to the arm jersey sleeves (long or short).

In one example, zippered line 3045 forms the edge that joins elastic seam line 304 joins the jersey torso front garment portion 302 and the jersey torso back garment portion 301. In one example, within the anchor 308 there is a cross-piece pinion and elastic band 204 assembly 3086. The cross-piece-pinion is perpendicular to the longitudinal direction of elastic band 204, at the terminal end of elastic band 204, serving to anchor and distribute the pulling forces of elastic band 204 to the rest of anchor 308 and, therefore, spreading the forces spatially between the ant-arm jersey sleeves garment portion 202 and the torso garment portions, front 302 and back 301. In one example, the cross-piece pinion in assembly 3086 is a cylinder.

Fig. 22B is a longitudinal cross-sectional view (of cut 22B in Fig. 22A) of attachment of a terminal end of the elastic line or band to the outer surface of the airfoil garment material, forming a type II locking anchor for use as a left (or right) hand side torso anchor. In one example, elastic band 204, which defines the cusp shaped trailing edge of the ante-arm airfoil, intersects at an oblique angle the garment near the seam 304 to torso garment portions, front 302 and back 301 (as shown in Fig. 22A).

In one example, cross-piece pinion of assembly 3086 is disposed within the material of anchor 308 and serves as means for anchoring elastic line or band 204 to anchor 308, which, in turn, distributes the tension forces into a spatial area of the garment material.

In one example, elastic band or line 204 terminates in an eyelet, enabling elastic band or line 204 to be removed and reattached by sliding band or line 204 unto cylindrical cross-piece pinion of assembly 3086.

In one example, the cross-piece pinion of assembly 3086, locks into the type II locking torso anchor 308. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken.

In one example, stretchable material surface 2041 lies parallel to garment material portion 202 on the skin side of the wearer and at some angle to the skin. Fig. 22C is a skin view of attachment of a terminal end of the cusped elastic line to the skin surface of the airfoil garment material, forming a type II locking anchor for use as a left-side torso anchor. In one example, Fig. 22C is the reverse, skin side of torso anchor 308 where garment portions are shown as 30G, 302’, 202’. In one example, Fig. 22C illustrates one example of the layout of the flat elastic lines 303 and 304 as disposed on the skin side of jersey torso garment portions 30G and 302’.

In one example, elastic band 204, which terminates into the airfoil cusp shaped trailing edge, 2044 is covered on the skin side by a stretchable garment material 2041 and is attached to the garment material portion 202 at the seams 2042, as illustrated also in Fig. 2 ID.

In one example, zippered line 3045 forms the edge that joins elastic seam line 304 joins the jersey torso front garment portion 302 and the jersey torso back garment portion 301.

Fig. 22D is an orthogonal cross sectional view (of cut 22D in Fig. 22A) of the left torso flat elastic band 303. As illustrated, elastic seam 303 is disposed under (in the skin side of) garment portions 301 (30G) and 302 (302’) at their seam.

Fig. 22E is an orthogonal cross sectional view (of cut 22E in Fig. 22A) of the jersey back side of a zipper detachable flat elastic band 304, forming the attachment between ante-arm of the left (long or short) jersey sleeves and the back side of the torso component of the jersey 301.

In one example, the flat elastic band 304 is zippered at the edge (zippered line) 3045.

In one example, Fig. 22E is a cross sectional view of attachment of a terminal end of the flat elastic line 304 to the outer surface of the airfoil garment material, forming a type II locking anchor for use as a torso anchor 308. As illustrated, garment portion 304 is disposed over garment portions 301 and 202 at their seam. Fig. 22F is an orthogonal cross sectional view (of cut 22F in Fig. 22A) of the jersey back side of a zipper detachable flat elastic band 304, forming the attachment between ante-arm of the left (long or short) jersey sleeves and the front side of the torso component of the jersey 302.

In one example, Fig. 22F is a cross sectional view of attachment of a terminal end of the flat elastic line 304 to the outer surface of the airfoil garment material, forming a type II locking anchor for use as a torso anchor 308. As illustrated, garment portion 304 is disposed over garment portions 302 and 202 at their seam.

Fig. 22G is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type II locking anchor 308 for use as a right hand side torso anchor 308. This anchor joins the end of one cusped shaped elastic band 204 a triple juncture to torso flat elastic band 303 and shoulder flat elastic band 304. The juncture to the shoulder elastic band 304, which goes around the armsyce, occurs at two points on torso anchor 308. In one example, the type II locking anchor 308 is placed on the intersection seam elastic band 303 of the back torso garment portion 301 and the front torso garment portion 302 to garment portion 202 of ante-arm (long or short) jersey sleeves.

In one example, withhin the anchor 308 there is a cross-piece pinion and elastic band 204 assembly 3086. The cross-piece-pinion is perpendicular to the longitudinal direction of elastic band 204, at the terminal end of elastic band 204, serving to anchor and distribute the pulling forces of elastic band 204 to the rest of anchor 308 and, therefore, spreading the forces spatially between the ant-arm jersey sleeves garment portion 202 and the torso garment portions, front 302 and back 301. In one example, the cross-piece pinion in assembly 3086 is a cylinder. Fig. 22H is a skin view of attachment of a terminal end of the cusped elastic line to the skin surface of the airfoil garment material, forming a type II locking anchor for use as a right-side torso anchor. In one example, Fig. 22H is the reverse, skin side of torso anchor 308 where garment portions are shown as 30G, 302’, 202’. In one example, Fig. 22H illustrates one example of the layout of the flat elastic lines 303 and 304 as disposed on the skin side of jersey torso garment portions 30G and 302’.

In one example, elastic band 204 which terminates into the airfoil cusp shaped trailing edge 2044 is covered on the skin side by a stretchable garment material 2041 and is attached to the garment material portion 202 at the seams 2042, as illustrated also in Fig. 2 ID.

Waistband.

In examples, disclosed is a velcro elastic waist band on the bottom of jersey and the ridding pants to preserve aerodynamic shape continuity.

Fig. 23 is a left side plan view of the jersey 300 over pants 100 to illustrate attachment of the two garments by a waist lock assembly 400 (location indicated by an arrow, assembly 400 not illustrated in this Fig.), the left side plan view as seen from exterior side of the garment as exposed to the air. In one example, a detachable flat elastic band seam 305 wraps around the waist portion of jersey 300. In one example, a flat elastic band seam 303 joins the bodice portions 301 and 302. In one example, a downward pointing rounded triangular area 306 illustrates the position for waist lock assembly. In one example, rounded triangular area 306, the location for the waist anchor, is located at the two intersections of flat elastic band seam 303 with the flat elastic band 305 of the waist, one intersection on each side of the jersey 300. In one example, a flat elastic band 112 wraps around the top waist edge of the upper portion of airfoil- leggings or shorts 101. Flat elastic band 112 serves to hold upper portion of airfoil-leggings or shorts 101 i-n position on the user’s body. Flat elastic band seam 305 of jersey 300 serves to hold the airfoil-enhanced jersey 300 in position around the user’s body / torso at the waist. In one example, the separation of the upper portion of airfoil-leggings or shorts 101 from the jersey 300 allows selection of either one or both airfoil enhanced jersey and pants to be deployed, or the interchanging of different types of styles of the airfoil enhanced jersey with airfoil-enhanced pants. The rounded triangular area 306, the location for the waist anchor, serves as a location to place a means for attachment of the upper portion of airfoil-leggings or shorts 101 to the jersey. The location, at the sides of the waist, provides a convenient location for ease in attachment and detachment of the two garments from each other. Further, the location, at the intersection of the elastic band seams 303 and 305, enables anchoring of the pants and jersey relative to each other. This provides a pre-engineered, stable tension discharge of loads generated during the deployment and operation of the torso and leg transient airfoils, maintaining also a smooth shape continuity of the body conforming garment. The smooth shape continuity of the body conforming garment is an important and desirable feature for aerodynamic drag reduction.

Fig. 23A is a left side plan view of the jersey 300 to illustrate the fixed attachment component 430 of waist lock assembly 400 to the under side (skin side or reverse side) of jersey 300. In one example, component 430 is affixed to detachable flat elastic band seam 305’. In one example, female receiving snap fastener 412 (also, Fig. 23D) of a waist lock assembly 400 is placed in the rounded triangular area 306 on the backside 305’ of flat elastic band seam 305. Female receiving snap fastener 412, in one example, mates with a component 422 (Figs. 23B and 23E) that is placed on flat elastic band 112 area of the top waist edge of upper portion of airfoil-leggings or shorts 101. In one example, female receiving snap fastener 412 is shaped in the downward pointing rounded triangle shape. In one example, female receiving snap fastener 412 forms a wall that encloses the downward pointing rounded triangle shape. In one example, female receiving snap fastener 412 forms a wall of downward pointing rounded triangle shape. The interior area of the downward pointing triangular shape inside the wall formed by female receiving snap fastener 412 is open, for receiving a counterpart male snap fastener 422 (Figs. 23B and 23E) to be inserted into female receiving snap fastener 412. This shape enables one- handed attachment and release, quick attachment and release, and sufficient attachment strength to anchor the tensions of the jersey to the pants or shorts. In one example the female receiving snap fastener 412 has, attached to it, a downward pointing rigid lip extension 413 (not illustrated) to ease the dis-engagement of the fastener.

Fig. 23B is a left side plan frontal view of the upper portion of airfoil-leggings or shorts 101 showing the fixed attachment of component 410 of waist lock assembly 400 to the outer (air) side of upper portion of airfoil-leggings or shorts 101. In one example, male snap fastener 422 (also, Fig. 23E) of a waist lock assembly 400 is placed on flat elastic band seam 112 of upper portion of airfoil-leggings or shorts 101. Male snap fastener 422, in one example, mates with a female receiving snap fastener 412 (Figs. 23A and 23D) that is placed in the rounded triangular area 306 on the backside 305’ of flat elastic band seam 305. In one example, male snap fastener 422 is shaped in the downward pointing rounded triangle shape. In one example, male snap fastener 422 forms a wall that encloses the downward pointing rounded triangle shape. In one example, male snap fastener 422 forms a wall of downward pointing rounded triangle shape. This shape enables one-handed attachment and release, quick attachment and release, and sufficient attachment strength to anchor the tensions of the jersey to the pants.

Fig. 23C is a cross sectional exploded or separated view of flat elastic band 305 of jersey 300 over flat elastic 112 of upper portion of airfoil-leggings or shorts lOlpants 100. Dashed arrows 307 show the arrangement of jersey 300 over the upper portion of airfoil-leggings pants 100 or shorts 101 when wrapped around the waist, held by elastic bands 305 and 112. Waist lock assembly 400 (not illustrated in this Fig.) is disposed between these two garment pieces, at the sides of the wearer, waist lock assembly component 430 attached to jersey 300 and waist lock assembly component 410 attached to upper portion of airfoil-leggings or shorts 101. Fig. 23D is a cross sectional view of waist lock assembly component 430 as affixed to jersey band seam 305. In one example, female receiving snap fastener 412 is shaped in the downward pointing rounded triangle shape. In one example, snap fastener is made of a resilient, flexible plastic material that is able to slightly bend outward of the rounded triangle shape when a counterpart male snap fastener is inserted into the interior triangle region. In one example, perpendicular to the surface of rounded triangular area 306, snap fastener 412 has straight outer walls and a French Curve inner wall that narrows towards the top opening of female snap fastener. In one example, a counterpart male fastener 422 with bulging outer wall pushes into the top opening of female receiving snap fastener 412, pushing the walls of female receiving snap fastener 412 slightly outward, while the bulging outer wall of counterpart male fastener 422 is pushed slightly inward. As counterpart male fastener 422 penetrates by force into female receiving snap fastener 412, the french curve walls of the female receiving snap fastener 412 and counterpart male fastener 422 become congruent, enabling the walls of female receiving snap fastener 412 and counterpart male fastener 422 to return to their original, relaxed positions. In a preferred example, the mating of female receiving snap fastener 412 and penetrating counterpart male fastener 422 causes a snapping sound, alerting the user of success in mating waist lock assembly components 410 and 430 of waist lock assembly 400. In one example, the bulging inner wall at the top of the female receiving snap fastener 412 snugly holds the inwardly placed bulging outer wall of the counterpart male fastener 422, providing, perpendicular to the garments, pull resistance to impede unwanted withdrawal of the male fastener.

Fig. 23E is a cross sectional view of waist lock assembly component 410 as affixed to pants band 112. In one example, a penetrating male fastener 422 is shaped in the downward pointing rounded triangle shape. In one example, the male snap fastener is made of a resilient, flexible plastic material that is able to slightly bend inward of the rounded triangle shape when penetrating into a counterpart female receiving snap fastener 412. In one example, perpendicular to the surface of waist lock assembly component 410, penetrating male fastener 422 has straight inner walls and a French Curve outer wall that enlarges or bulges towards the top opening of the snap fastener. In one example, male fastener 422 with bulging outer wall pushes into the top opening of counterpart female receiving snap fastener 412, pushing the walls of female receiving snap fastener 412 slightly outward, while the bulging outer wall of male fastener 422 is pushed slightly inward. As counterpart female receiving snap fastener 412 is penetrated by force by male fastener 422, the french curve walls of the male fastener 422 and the counterpart female receiving snap fastener 412 become congruent, enabling the walls of male fastener 422 and counterpart female receiving snap fastener 412 to return to the original, relaxed positions. In a preferred example, the mating of female receiving snap fastener 412 and penetrating counterpart male fastener 422 causes a snapping sound, alerting the user of success in mating waist lock assembly components 410 and 430 of waist lock assembly 400.

Thus, in one example, disclosed is an air foil garment having: at least a bodice portion adapted to at least partly cover a torso portion of a person wearing the bodice portion; at least one pant portion adapted to at least partly cover a hip and/or leg portion of a person wearing the pant portion; with the bodice portion having a lower hem section and the pant portion having a waistband section; and the hem section and the waistband section comprising corresponding fastening means adapted to detachably join the bodice portion and the pant portion.

In a further example of the bodice portion, the fastening means are at least one out of the group including: a zipper; a Velcro fastener; a cord thread-ably attachable to corresponding eyelets arranged within the hem section and the waistband section; a plurality of snap fasteners.

In further example of either of the two foregoing examples, when joined, the hem section and the waistband section are arranged in an overlapping manner. In further example, when joined, the hem section and the waistband section are joined on butt to form a flash transition along the distal sides of the hem section and the waistband section.

In one example, the hem section overlaps the waistband section on a distal side of the waistband section. In further example of either of the five foregoing examples, the fastening means are adapted to transfer tensile forces between the bodice portion and the pant portion occurring during wearing operation of the garment particularly generated by a suspension line of an airfoil portion anchored to the garment in a waist region thereby introducing tensile forces into a cloth material of the bodice portion or the pant portion.

Anchoring to hands and feet.

In examples, disclosed is a bodice portion and pant portion of an airfoil garment having glove/ sock portions locked to hands/feet in a positive locking manner.

Fig. 24A is a 3-D perspective inner front upper view of a representation of a human right foot, a knuckle and big toe view, showing arrangement and placement of an example of ankle anchoring components for a leg airfoil.

At the ankle of the human leg can be viewed as essentially cylindrical, symmetrical airfoil with to thickness ratio equal to 1. For aerodynamic drag reduction reasons, it is desirable to have the terminal leg airfoil around the ankle at elastic band 109 with a chord to thickness ratio larger than 1. Evidently, this feature is desirable since it also improves the aerodynamic drag reduction of the whole airfoil Leggings.

In some examples of present invention, it is desirable to position the terminal airfoil ankle anchor 106 at various distances away from the ankle, or to provide greater anchoring for the terminal airfoil than provided by the leggings or the leggings and ankle elastic band 109.

In one example of present invention, illustrated in Fig. 24B, at elastic band 109, the leggings terminal airfoil cusp trailing edge 104 and ankle anchor 106 are disposed on the ankle. In this configuration the terminal leg airfoil has a chord to thickness ratio close to 1. In one examples, at elastic band 109, the leggings terminal airfoil cusp trailing edge 104 and ankle anchor 106 (shown in Fig. 24B) are disposed at various positions away from the ankle. In further example, the terminal leg airfoil has a chord to thickness ratio larger than 1. In these examples, ankle anchor 106 is further supported by a foam material ankle conforming support base 110, as illustrated in Fig. 24C. In one example, the foam material ankle conforming support base 110 is disposed over the base of the calcaneal (Achilles) tendon.

In one example, the foam material ankle conforming support base 110 is attached on two sides to flat elastic ankle band member 109, as illustrated in Fig. 24C.

In one example, a wearable ankle anchor assembly 106 is disclosed. The ends of the leggings front garment portion 103 and back garment portion 102 of the airfoil leggings are attached to a flat elastic ankle band member 109 that wraps around the ankle and attaches (in one example) at a seam 116 to other members 115 by wrapping around the foot bridge and the valley between the toes and the heel. An edge seam 113 enables the toes and knuckles to protrude, providing them freedom of movement. An edge seam 114 wraps around the heel below the ankle and the talus bone.

In one example, ankle anchor 106 is disposed on ankle band member 109 on the ankle, above the talus bone over the base of the calcaneal (Achilles) tendon and holds one end of elastic band 104 that forms the cusp trailing edge of the leg airfoil.

In some examples, ankle anchor 106 is disposed at various distances away from the ankle on ankle band member 109 over and around the foam material ankle conforming support base 110, as illustrated in Fig. 24C, above the talus bone, and holds one end of elastic band 104 that forms the cusp trailing edge of the leg airfoil.

In one example, a foot sock member 115 extends from ankle band member 109 to use the valley around the foot behind the toe knuckles to further secure the anchoring position of ankle anchor 106, ankle elastic band member 109 and the foam material ankle conforming support base 110 (Fig. 24C). Opening edge 113 of foot sock extension member 115 provides an opening for the five toes of the foot. Opening edge 214 of foot sock extension member 115 provides an opening for the heel of the foot.

In one example, ankle anchor 106 is a type I locking anchor for the airfoil elastic band 104.

In one example, ankle anchor 106 is a type II adjustable anchor that enables the adjustment of tension placed on the airfoil elastic band 104.

From this perspective view, the positioning and area of ankle anchor 106 is more fully visible, positioned above the talus bone, near the area of the ankle. In some examples, as illustrated in this perspective, the ankle anchor 106 disposed on ankle elastic band member 109 rests over the calcaneal (Achilles) tendon.

In on example, ankle anchor 106 is disposed on ankle band member 109 on the ankle, above the talus bone and over the base of the calcaneal (Achilles) tendon and holds one end of elastic band 104 that forms the cusp trailing edge of the leg airfoil.

In some examples, ankle anchor 106 is disposed at various distances away from the ankle on ankle band member 109 over and around the foam material ankle conforming support base 110, above the talus bone, and holds one end of elastic band 104 that forms the cusp trailing edge of the leg airfoil.

In one example, ankle anchor 106 is a type I locking anchor for the airfoil elastic band 104. In one example, ankle anchor 106 is a type II adjustable anchor that enables the adjustment of tension placed on the airfoil elastic band 104.

Fig. 24C is a plant bottom view of a representation of a human foot, showing arrangement and placement of components of an example of ankle anchoring components for a leg airfoil.

In one example, foam material ankle conforming support base 110 sits above the talus bone and over the base of the calcaneal (Achilles) tendon. In some examples, foam material ankle conforming support base 110 has various lengths behind the base of the calcaneal (Achilles) tendon.

In one example, flat elastic ankle band member 109 continuously wraps around the ankle (Fig. 24A and Fig. 24B) and foam material ankle conforming support base 110 and attaches to leg ankle anchor 106 at the points farthest from the base of the calcaneal (Achilles) tendon.

In one example, and foam material ankle conforming support base 110 is flush with flat elastic ankle band member 109 at a seam 116.

From this perspective view, the lower part of foot sock member 115 is visible as it wraps around the foot bridge (arch) from behind the toe knuckles at edge 113 to edge 114 just ahead of the heal.

In one example, foam material ankle conforming support base 110 sits above the talus bone and over the base of the calcaneal (Achilles) tendon. In some examples, foam material ankle conforming support base 110 has various lengths behind the base of the calcaneal (Achilles) tendon. In some examples, ankle anchor 106 is disposed at various distances away from the ankle on ankle band member 109 over and around the foam material ankle conforming support base 110, above the talus bone, and holds one end of elastic band 104 that forms the cusp trailing edge of the leg airfoil.

In one example Fig. 24C illustrates the placement of ankle anchor 106 disposed on the foam material ankle conforming support base 110 at the end opposite to the calcaneal (Achilles) tendon.

Fig. 24G is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type II adjustable anchor for use as a legging ankle anchor. Fig. 24G illustrates an example of an air view of example of an ankle type II adjustable anchor 106. In one example, the airfoil cusp shaped trailing edge and elastic band 104 is disposed from an ankle type II adjustable anchor 106. A cap 1065 is disposed on the axis 1066 of anchor 106. Cap 1065 serves as a knob for adjustment of the tension of elastic band 104. In one example a pin 1048 acts as a guide to assist guiding the elastic or band 104 to and from about a spool 1067 (as shown in Fig. 24H). By turning cap or knob 1065, elastic line 104 is wound or unwound about axis 1066 and thus wound or unwound about spool 1067. In one example, detents (not illustrated) or protrusions hold cap or knob 1065 in place by manually rotating knob 1065 to a user preferred setting. In one example, knob 1065 houses a small motor or similar actuating mechanism (not illustrated) electronically controlled through a WIFI or radio interface, to a user preferred user setting. In one example, a clicking sound from the detents or protrusions assist the user in knowing the amount of the cap or knob 1065 has been rotated. Fig. 24H is a longitudinal cross sectional view (of cut 24H in Fig. 24G) of a terminal end of the elastic line to the surface of the airfoil garment material, forming a type II adjustable anchor for use as a legging ankle anchor 106.

In one example, the foam material ankle conforming support base 110 is disposed over the base of the calcaneal (Achilles) tendon. In one example, the interface 1106 between the foam material ankle conforming support base 110 and the calcaneal (Achilles) tendon is motion self-adjustable. In one example, interface 1106 and support base 110 are not present. In one example, adjustable anchor 106 includes a fastener (not illustrated) for attaching a support base 110 and interface 1106. In one example, the type II adjustable ankle anchor 106 and the foam material ankle conforming support base 110 are disposed over the calcaneal (Achilles) tendon above the talus bone by flat elastic ankle band 109 (Fig. 241), which wraps around the ankle.

In one example, elastic band 104 integrates with ankle anchor 106 to distribute the stresses in the attachment to garment portion 102. In one example, a pin 1048 acts as a guide to assist guiding the elastic or band 104 to and from about a spool 1067. By turning cap or knob 1065, elastic line 104 is wound or unwound about axis 1066 and thus wound or unwound about spool 1067. In one example, detents (not illustrated) or protrusions hold cap or knob 1065 in place by manually rotating knob 1065 to a user preferred setting. In one example, knob 1065 houses a small motor (not illustrated) electronically controlled through a WIFI interface, to a user preferred user setting.

Fig. 24D is a terminal cross sectional view (of cut 24D in Fig. 241) of the flat elastic band that secures the type II adjustable anchor to the legging around the ankle. In one example, at the terminal end by the ankle flat elastic band 109 is disposed under the legging front garment potion 101 and the legging back garment potion 102. In one example, the flat elastic band 109 is disposed around the ankle and type II adjustable anchor 106 on one side and the a foam material ankle conforming support base 110 on two other sides as illustrated in Fig. 25 A and Fig. 25C.

Fig. 24F is a cross sectional view of an example of a cusped shaped trailing edge airfoil, elastic line and housing disposed on the inner side of the garment material for connecting the type I locking leg anchor and the type II adjustable ankle anchor.

Fig. 24F illustrates one example of a cross sectional view of a cusped shaped trailing edge airfoil, elastic line and housing disposed on the inner side of the garment material for connecting the leg and ankle anchors. In one example, Fig. 24F illustrates a cross-section view of a cusped shaped trailing edge of the leg airfoil as well as elastic line or band 104 disposed on the inner side of the garment material. In examples, the cusped shaped trailing edge elastic line or band is used for either or both the torso airfoil and/or the leg airfoil. As illustrated, a back portion of garment portion 102 of the airfoil leggings garment portion 102 drape over the longitudinally stretchable elastic band 104. This forms the cusp-shape of the trailing edge of the leg airfoil from the leg type I locking anchor to the type II adjustable ankle anchor. In one example, the garment material 102 and the elastic band 104 form two sides of a safety housing for elastic band 104. The third side of the safety housing for elastic band 104 is defined by the stretchable material 1041 at seams 1042 to garment material 102. The two longitudinally stretchable elastic material seams 1042 connect the stretchable material surface 1041 to garment portion 102 around and to envelop the elastic line or band 104. This housing of elastic line 104 within the ‘triangular’ volume define by the garment material 102 and the stretchable material 1041 imparts protection to the wearer if elastic line 104 breaks.

Thus, in one example, disclosed is a bodice portion of an airfoil garment having sleeves, the sleeves adapted to get at least one airfoil portion attached thereto, thereby causing tensile forces tending to move the sleeves in a proximal direction towards a torso of a person wearing the bodies portion whereas at distal ends of the sleeves glove portions are provided adapted to engage with fingers and/or interspaces between fingers of the person wearing the bodice portion in a positive locking manner with respect to a proximal direction of the forces. In a further example of the bodice portion, the glove portion is tethered or detachably mounted to the distal ends of the sleeves.

In further example of either of the two foregoing examples, the glove portion comprises at least one loop portion adapted to be arranged within an interspace between two fingers of the person wearing the bodice portion.

In further example of the previous example, the loop portion is formed of an elastic material, particularly an elastic fabric material or at least comprises an elastic section being stretchable by tensile forces above certain predetermined threshold values.

In one example, disclosed is a pant portion of an airfoil garment having pants legs, the pant legs adapted to get at least one airfoil portion attached thereto thereby causing tensile forces tending to move the pants legs in a proximal direction towards a torso of a person wearing the pants portion whereas at distal ends of the pants legs sock portions are provided adapted to engage with the sole of a foot of the person wearing the pant portion in a positive locking manner with respect to a proximal direction of the forces.

In further example of the previous example, the sock portion is tethered or detachably mounted to the distal ends of the pants legs.

In further example of the previous two examples, the sock portion comprises at least one loop portion adapted to be arranged around the sole of a foot of the person wearing the pant portion.

In further example of the previous example, the loop portion is formed of an elastic material, particularly an elastic fabric material or at least comprises an elastic section being stretchable by tensile forces above certain predetermined threshold values. In further example of the previous four examples, the sock portions of the pant portion are adapted not to cover the heel of the foot of the person wearing the pant portion.

Fig. 25 A is a top plan view of attachment of a terminal end of the elastic line to the outer surface of the airfoil garment material, forming a type I locking anchor for use as an elbow anchor. In one example, this is a front view of the garment in the area of the elbow anchor 105, as seen from exterior side of the garment as exposed to the air. In one example, elastic band 104 terminates into the airfoil cusp shaped trailing edge and is attached to the garment material, for example, garment portion 102. In this example, the tensional pull load from elastic band 104 is distributed away from a point force to a surface force, relieving excess stress on the garment material and reducing tendency to tear from the repeated pulling force. In one example, garment material 102 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, elbow anchor 105 integrates with an elastic band 104. Elastic band 104 is longitudinally stretched within a ‘triangular’ volume defined by the garment material 102 on two sides and a portion of the stretchable material 1041 disposed on the inner side of the cusp airfoil trailing edge and connected to the garment material 102 at seams 1042. The outward apex edge of elastic band 104 pushes on garment portion 102 from underneath, forming an apex shape to an outer surface portion 1044 of the garment 102. Within the anchor 105 there is a cross-piece pinion and elastic band 104 assembly 1056. The cross-piece-pinion is perpendicular to the longitudinal direction of elastic band 104, at the terminal end of elastic band 104, serving to anchor and distribute the pulling forces of elastic band 104 to the rest of anchor 105 and, therefore, spreading the forces spatially to the garment portion 102. In one example, the cross piece pinion in assembly 1056 is a cylinder.

Fig. 25B is a longitudinal cross sectional view (of cut 25B in Fig. 25A) of attachment of a terminal end of the elastic band or line 104 to the surface of the airfoil garment material 102, forming a type I locking anchor for use as an elbow anchor 105. In one example, illustrated is in an elbow anchor axial cross sectional of the cusp trailing edge and elbow anchor as attached to garment. In one example, garment material 102 is the upper back portion or ante-arm of the airfoil jersey sleeves. In one example, cross-piece pinion of assembly 1056 is orthogonal to elastic band or line 104. In one example, the cross-piece pinion of assembly 1056 is a cylinder. In one example, elastic band or line 104 terminates in an eyelet, enabling elastic band or line 104 to be removed and reattached by sliding band or line 104 unto cylindrical cross-piece pinion of assembly 1056. In one example, the cross-piece pinion of assembly 1056, locks into the type I locking elbow anchor 105. Thus, a user can select different bands or lines of different tensions strengths. Thus, a user can replace a line or band that has lost its tension and/or has broken.

Fig. 25C is the skin view of the attachment of a terminal end of the cusped elastic line to the surface of the airfoil garment material, forming a type I locking anchor for use as an elbow anchor. Fig. 25C in one example is an underneath view of the garment in the elbow area of anchor 105, as seen from interior side of the garment, the side touching the skin. As illustrated, the cusp apex shapes the outer surface of the garment into the desired trailing edge shape.

In one example, Fig. 25C illustrates the skin view of the garment in the area of the elbow anchor 105, as seen from the interior side of the garment as exposed to the skin. In one example, elastic band 104 which terminates into the airfoil cusp shaped trailing edge 1044 is covered on the skin side by a stretchable garment material 1041 and is attached to the garment material portion 102 at the seams 1042 as illustrated in Fig. 25D.

Fig. 25D is a cross-section view of an example of a cusped shaped trailing edge airfoil elastic line disposed on the inner side of the garment material. Fig. 25D in one example is a cross sectional view of an example of a cusped shaped trailing edge airfoil elastic line and housing disposed on the inner side of the garment material for connecting the elbow and torso anchors. In one example, Fig. 25D illustrates a cross-section view of a cusped shaped trailing edge of the torso airfoil as well as elastic line or band 104 disposed on the inner side of the garment material. In examples, the cusped shaped trailing edge elastic line or band is used for either or both the torso airfoil and/or the leg airfoil. As illustrated, an upper back portion (ante-arm) of garment portion 102 of the airfoil jersey sleeves drape over the longitudinally stretchable elastic band 104. This forms the cusp-shape of the trailing edge of the torso airfoil at the elbow. In one example, the garment material 102 and the elastic band 104 form two sides of a safety housing for elastic band 104. The third side of the safety housing for elastic band 104 is defined by the stretchable material 1041 at seams 1042 to garment material 102. The two longitudinally stretchable elastic material seams 1042 connect the stretchable material surface 1041 of the garment portion 102 around and to envelop the elastic line or band 104. This housing of elastic line 104 within the ‘triangular’ volume define by the garment material 102 and the stretchable material 1041 imparts protection to the wearer if elastic line 104 breaks.
