Definitions
- This invention relates generally to a backpack with side bolsters and, more specifically, to side bolsters for stabilizing the backpack and providing ventilation between the backpack and a wearer of the backpack.
- Conventional backpacks are generally configured with either an internal or external frame coupled to a compartment for carrying gear, such as, but not limited to clothing, food, water bottles and sleeping gear.
- Internal frame backpacks are generally more stable, but the weight or load of the gear in the load compartment should be selectively distributed to help improve the vertical and rotational stability of the backpack relative to a wearer.
- one type of conventional internal frame backpack includes flexible stays arranged within frame material. The flexible stays may be arranged vertically, horizontally, or in some other direction in an attempt to transfer the load in the load compartment to the shoulder straps and the waist belt of the backpack.
- backside armor is generally curved or contoured to at least somewhat conform to the general shape of a soldier's back.
- Conventional backpacks tend to ride on and slide relative to the backside armor.
- the backpack may become unstable relative to the backside armor.
- soldier's often have to highly tighten the waist belt, which in turn presses the backside armor into the soldier's back and entraps body heat.
- U.S. Patent Publication No. 2005/02025634 to Han describes cushion pads for backpacks.
- Each cushion pad includes a porous filter which is placed inside the net fabric to dissipate heat to the atmosphere, and a sheet which is made of a material such as polyurethane and layered on a surface of the porous filter. The sheet is inserted along with the porous filter into a space defined between the net fabric and the cloth of the backpack.
- the cushion pads provide improved ventilation and elasticity to the backpack and the shoulder straps of the backpack.
- U.S. Patent Publication No. 2004/0134955 to Williams describes a ventilation system that may be attached to a conventional backpack.
- the ventilation system elevates the backpack, hydration pack, fanny pack, or the like off the wearer's skin.
- the ventilation system includes pliable supports that provide for pressure relief and good ventilation between a wearer's back and the conventional backpack.
- Williams suggests that the purpose of the invention is to support and elevate the backpack off of the wearer's skin or other bodily part in order to reduce the pack's surface area in contact with the wearer, thusly increasing ventilation and exposed wearer's body surface area to maximize cooling, therefore reducing perspiration and water consumption, while increasing performance, comfort, and physical and mental endurance.
- Japanese Patent No. JP09252840 by Shigeharu describes a back panel and cushioning system that includes a back panel that couples to the backpack.
- the back panel substantially over a width of the wearer's back and includes left and right edges that are curved in a direction away from the back.
- Cushioning devices are coupled to the left and right edges and generally extend from an upper edge to a lower edge of the back panel. Shigeharu suggests that the space created between the back panel and the wearer's back because the cushioning devices offset the backpack from the wearer's back provides improved ventilation.
- the present invention generally relates to a backpack having stabilizing and ventilating side bolsters, and a method for securing and releasing the side bolsters.
- a backpack includes a frame; a load compartment coupled to the frame; shoulder straps coupled to the frame; and a pair of side bolsters coupled to the frame by fastening devices.
- the side bolsters are comprised of a semi-rigid material, such as high- density polyurethane or polystyrene foam.
- the side bolsters include a plurality of channels to allow air flow through the side bolsters and away from the wearer.
- the side bolsters may be firmly coupled to the frame by fastening devices including a combination of straps and clips disposed either through slots in the side bolster or around the perimeter of the side bolster.
- the density of the side bolsters is in the range of 0.5 lbs/ft 3 to 10.0 lbs/ft 3 , in a more preferred embodiment the range of density is 2.0 to 4.0 lbs/ft 3 .
- the side bolsters function to cooperate with the frame and stabilize the backpack under load while providing improved ventilation between the backpack and a back side of a wearer of the backpack.
- the side bolsters have a center axis oriented substantially vertically to structurally cooperate with the frame in providing stability for the load compartment.
- the center axes of the side bolsters are spatially separated in a forward direction from the forward surface of the frame. The side bolsters thereby contour around the backside of the wearer to provide stability for the load compartment and to allow ventilation.
- the channels may be formed in a circular or oval cross-section to provide stabilizing support for the backpack while allowing air flow in a direction away from the forward surface of the backpack.
- the channels are formed laterally from one side of the side bolster to the other side to permit air flow away from the backside of the wearer.
- the side bolsters may be formed for a particular environment, for a particular body type, or for particular loads to be carried in the backpack.
- the side bolsters may be manufactured with a variable stiffness, size, material, density, and other aspects of the side bolsters.
- a stabilizing system for a backpack includes the pair of side bolsters made from a semi-rigid material, and a pair of sleeves coupled to the backpack and sized to receive the side bolsters.
- the sleeves are made from a breathable material, wherein a side bolster is arranged in a sleeve to provide an amount of vertical stabilization to the backpack.
- the sleeves are horizontally spaced apart from each other by approximately the width of the back pad and the sleeves are oriented approximately vertically.
- the sleeves are made from a breathable material and the side bolsters cooperate with the sleeves to move air from the back pad area and away from the spaced apart region formed by the sleeves in a direction away from the back pad.
- the sleeves may include a zipper for opening the sleeve to access the side bolsters for removal.
- the sleeve may include other means of securing the side bolster to the backpack, such as a hook and loop fastener or snap buttons.

- backpack generally refers to a soft-covered carrier designed for carrying belongings or items on a person's back within the carrier.
- backpack includes, but is not limited to, carriers that may be referred to by other names such as a rucksack, knapsack, pack, carrier, bag, and daypack.
- At least one embodiment of the invention includes a backpack having stabilizing and ventilating side bolsters coupled to a frame.
- the backpack may be configured to operate in a variety of environments such as a in the military, on a climbing, hiking, or camping trip, or for general traveling.
- the side bolsters function to cooperate with the frame and stabilize the backpack under load while providing improved ventilation between the backpack and a back side of a wearer of the backpack.
- Stabilizing the backpack includes reducing or even preventing bulging when the backpack is under load.
- the side bolsters may be formed for a particular environment, for a particular body type, or for particular loads to be carried in the backpack. Stabilization also includes retaining the position of the pack relative to the body (and any body armor) of the wearer.
- the bolsters aid the side-to-side position retention (both lateral shifting and rocking) of the pack relative to the wearer.
- FIGURE 1 shows a backpack 100 having a load compartment 102 coupled to a shoulder harness 104 and a waist belt 106.
- the backpack includes a back pad 108 coupled to vertically oriented side bolsters 1 10, which are retained in vertically oriented breathable sleeves 1 1 1.
- the load compartment 102 structurally couples to a frame 1 12 (FIGURE 2).
- the backpack may further include a carrying handle 1 14, compression straps 116, and other accessory items that may take the form of webbing, straps, clips, zippers, pads, etc.
- FIGURE 2 shows the frame 112 that may be used to support the load compartment 102 according to an illustrated embodiment of the invention.
- the frame 1 12 includes flexible, yet sufficiently rigid vertically oriented stays 1 18 received in stitched pockets 120 of a soft covering 122.

- the frame may include horizontally oriented stays 128, which may be structurally coupled or integrally formed with the vertically oriented stays 1 18.
- the frame 1 12 is connected to the waist belt 106 and further includes connection devices 130 for coupling to the load compartment 102.
- the illustrated frame 1 12 is commonly referred to as a "soft- frame” because the stays are flexible enough to form and generally move with the wearer, yet structurally strong and stiff enough to support the load compartment 102, shoulder harness 104, and waist belt 106 even when the load compartment 102 contains a substantial amount of weight, for example more than thirty pounds (30 lbs.).
- the length, width, thickness, and material of the stays 1 18, 128 may be selected depending on a desired purpose of the backpack 100.
- FIGURES 3-5 show the side bolster 1 10 in both a rolled configuration (FIGURES 1 and 3) and in an unrolled configuration (FIGURE 2) according to an illustrated embodiment of the present invention.
- the side bolster 1 10 When placed in the breathable sleeves 1 1 1 (FIGURE 1) of the backpack 100 (FIGURE 1), the side bolster 1 10 would be in the rolled configuration.
- the rolled configuration permits the side bolster 1 10 to have a desired amount of bending stiffness, buckling strength, and structural stability for the purpose of cooperating with the frame 1 12 (FIGURE 2) and helping to stabilize the load compartment 102 (FIGURE 1) of the backpack 100 (FIGURE 1).
- Another purpose of the side bolster 1 10 is to offset or space the backpack 100 away from the back of the wearer.
- the side bolsters 100 have been found to be advantageous on military- style backpacks to stabilize the backpack 100 while maintaining the backpack 100 away from or nested and contoured with an armored plate (not shown) worn on the backside of a soldier (not shown).
- the side bolster 1 10 may be radially compressible, yet remain breathable to provide ventilation and have a cross-sectional stiffness that helps stabilize the backpack 100 with respect to the wearer.
- a first side portion 132 is coupled to a mid portion 134 of the side bolster 1 10.

- the side bolster 110 does not have to be coupled together with the fastening system 136 to hold its rolled configuration because the side bolster 1 10 may be rolled and then placed into the breathable sleeve 1 1 1 (FIGURE 1).
- the sleeve 11 1 is sized to maintain the side bolster 1 10 substantially in the rolled configuration.
- the side bolster 1 10 may be made from a woven, synthetic material 138 that when rolled and/or radially compressed still allows for airflow through the material 138.
- the side bolster 1 10 is made from a woven, polypropylene or polyethylene fabric or an open-celled foam having a first surface 140 spaced apart from a second surface 142 by a plurality of woven channels 144. Each channel 144 extends from a bottom end portion 146 to a top end portion 148 of the material 138.
- the material 138 may be a woven geotextile polypropylene fabric commercially available under the trademark PROPEX®.
- the side bolster 1 10 includes a generally circular cross-section, but it is appreciated that the cross- sectional profile of the side bolster 1 10 may take a variety of forms or shapes.
- FIGURE 4B the structural details of the side bolster 1 10 are shown in FIGURE 4B.
- FIGURE 4A is shown with the side bolster 110 in an un-rolled configuration for purposes of clarity, it is appreciated that the side bolster 110 may be completed by rolling a second side portion 149 towards the first side portion 132 and then either inserting directly into the breathable sleeve 11 1 (FIGURE 1) or using the fastening system 136 to maintain the side bolster 1 10 in the rolled configuration.
- FIGURE 4B shows a close-up view of a portion 1 10a of the side bolster 110 of FIGURE 4A.
- the side bolster 1 10 is a porous, mesh or breathable material 138 having a plurality of holes or openings 150.

- the frame 1 12 is connected to the waist belt 106 and further includes connection devices 130 for coupling to the load compartment 102.
- the illustrated frame 1 12 is commonly referred to as a "soft- frame” because the stays are flexible enough to form and generally move with the wearer, yet structurally strong and stiff enough to support the load compartment 102, shoulder harness 104, and waist belt 106 even when the load compartment 102 contains a substantial amount of weight, for example more than thirty pounds (30 lbs.).
- the length, width, thickness, and material of the stays 1 18, 128 may be selected depending on a desired purpose of the backpack 100.
- FIGURES 9A-9C show side bolster 110 according to an illustrated embodiment of the present invention.
- clips 1 17 When clips 1 17 are engaged through slots 121 to couple side bolsters 110 to frame 1 12, it provides structural stability for the purpose of cooperating with the frame 1 12 (FIGURE 8) and helping to stabilize the load compartment 102 (FIGURE 7) of the backpack 100.
- three channels 1 19 are formed laterally through side bolster 1 10 to allow air flow in a direction away from or toward the backpack and the backside of the wearer.
- the channels 1 19 may have circular, oval, or rectangular cross-sections with varying dimensions.
- the area formed by channels 1 19 is sufficient large enough to allow air flow and sufficiently small enough to allow side bolsters 1 10 to structurally cooperate with the frame.
- channels 1 19 may be a plurality of smaller channels.
- Slots 121 are formed laterally through side bolster 1 10 to receive the fastening devices 123 when coupling the side bolsters to the backpack (FIGURE 9C).
- the straps 1 15 and clips 1 17 (fastening devices 123) are releasable by squeezing clips 1 17 on either side of slot 121, which allows quick removal of the side bolsters from the backpack.
- one end of clip 1 17 includes a releasing mechanism that is positioned within slot 121 and slightly exposed beyond the perimeter of the side bolster. When squeezed inwardly and against the other end of the clip, the releasing mechanism releases clip 117 from the side bolster, thereby allowing removal of the side bolster from the backpack.
- Clip 1 17 is therefore releasable on the ends of the clip, as opposed to the side of the clips as with conventional clip systems. This configuration further provides structural support when the fastening devices secured the side bolster to the frame. Slots 121 are formed above and below channels 1 19 in a manner to provide structural stability backpack. It will be appreciated that other fasteners and means may be used for securing and releasing side bolsters 1 10 from the backpack through slots 121 or around the perimeter of the side bolsters.
- the side bolsters 1 10 have a center axis 125 oriented substantially vertically to structurally cooperate with frame 1 12 in providing stability for the load compartment 102.

- the side bolsters 1 10 thereby contour around the backside of the wearer to provide stability for the load compartment and to provide ventilation.
- FIGURE 9C illustrates the configuration of straps 1 15 and clips 1 17 as coupling side bolster 1 10 to the backpack.
- the upper slot 121 shows straps 1 15 and clips 1 17 in the disengaged state near the slot.
- the lower slot 121 shows straps 1 15 and clips 1 17 in the engaged state disposed through slot 121, whereby clips 1 17 extend through the length of slot 121.
- the side bolsters 1 10 may be comprised of various semi-rigid materials having various densities to help stabilize the backpack 100 with respect to the wearer.
- side bolsters 1 10 are comprised of high- density foam having a range of density of approximately 0.5 lbs/ft 3 to 10.0 lbs/ft 3 , in a more preferred embodiment the range of density is 2.0 to 4.0 lbs/ft 3 .
- Side bolsters 1 10 may alternatively be constructed of other materials. Closed or open cell materials may be used, including rubber or polymers. The density can be selected based on the load to be carried. The stiffness may vary based on the selection of the bolster material as well. The material may be progressively more dense or stiff as it extends away from the back of the user or may vary vertically in compressibility. Various materials and material arrangements may be employed to meet the needs of the load and the user.
- FIGURE 10 shows backpack 100 coupled to side bolsters 1 10 by fastening devices 123 according to an illustrated embodiment of the present invention.
- the center axes 125 or at least the forward-most portions of the side bolsters are spatially separated in a forward direction from the forward surface of the frame medially adjacent the bolsters, whereby the side bolsters 110 are provided to contour around the backside of the wearer to provide stability for the load compartment and ventilation.
- each side bolster assembly includes at least four straps 1 15 that are secured to frame 1 12 by stitching the ends of straps 1 15 to the fabric of frame 112. As described above, one pair of straps is secured to the frame near the upper portion of the side bolster, and another pair of straps is secured near the lower portion of the side bolster. Straps 1 15 are therefore secured to frame 1 12 behind side bolster 1 10 when it is secured to the frame by virtue of engaging clips 1 17 to one another (FIGURE 9C). This arrangement of the straps and clips strongly secures the side bolsters to the frame and prevents rotation and shifting of the side bolsters while wearing the backpack, which further adds to the stabilization of the backpack.
- Fastening devices 123 may include a plurality of straps and clips extending vertically over a substantial portion of the backpack 1 10 to provide additional structural support.
- two or more side bolsters 1 10 may be stacked vertically on one side of the back pad 108.

- Another purpose of side bolsters 1 10 is to offset or space the backpack 100 away from the back of the wearer.
- the side bolsters 1 10 have been found to be advantageous on military-style backpacks to stabilize the backpack 100 while maintaining the backpack 100 away from or nested and contoured with an armored plate (not shown) worn on the backside of a soldier (not shown).
- FIGURE 1 1 shows an alternate preferred embodiment wherein the side bolsters 1 10 are received in elongated, breathable sleeves 1 1 1 (the sleeves as shown in FIGURE 1).
- the bolstered ventilation and stabilization system 202 includes side bolsters 1 10 received in breathable sleeves 204.
- the breathable sleeve 204 includes an access system 206 for gaining access to inside the sleeve 204, and specifically for gaining access to side bolsters 1 10 for insertion or removal.
- the access system 206 takes the form of a side zipper 208 extending along at least a substantial length of the sleeve 204.
- the access system 206 may take other forms such as a top flap, top or bottom zipper, an internal zipper accessible from within the backpack 200, or other equivalent embodiments.
- the sleeves 204 may extend vertically over a substantial portion of the backpack 100 or may be truncated to have a shorter height, for example a height approximately equivalent to a height of the waist belt 106. Further, the sleeves 1 1 1 may take the form of a plurality of sleeves vertically aligned with one another and extending over the substantial portion of the backpack 100 or may be arranged in other configurations on the backpack 100. In one embodiment, the sleeves 204 are made from a woven fabric in which the selected weave pattern permits a substantial amount of airflow through the sleeves 204. Slots 121 of the side bolster 1 10 may not be necessary in this embodiment, but they may improve ventilation in cooperation with channels 1 19.
- the backpack with side bolsters may advantageously improve or enhance ventilation to the wearer's backside and may advantageously cooperate with the frame to increase the stability of the load compartment of the backpack.
- the side bolsters may be arranged to replace rigid plastic extension members located near the hip belts on some backpacks.
- Embodiments of the present invention also include a method of stabilizing the backpack by engaging the clips to secure the side bolsters to the frame of the backpack, including the step of releasing the clips to remove the side bolsters, as previously described in connection with FIGURES 7-1 1.
