Abstract
Description
- The present inventions relate generally to hip protectors.
- Hip fractures are a well-known problem, especially within elderly populations, that are frequently the result of falls and the associated impacts to the greater trochanter of the femur. Some conventional hip protectors include a wearable garment on which compressible foam pads are mounted. The garment positions the foam pads in the hip regions, and each pad is sufficiently sized to cover an entire hip region. The level of impact protection provided by the foam pads is a function of foam density. The relatively dense foams that are necessary to provide adequate protection (i.e., foam that will not “bottom out”) tend to be stiff. Alternatively, hard shell covers (which are very stiff) may be laminated onto more compressible foam pads. Turning to the pad supporting garments, the garments tend to be tight, much like bicycle pants, in an effort to maintain the pads in the intended location over the greater trochanter.
- The present inventors have determined that conventional garment-based hip protectors are susceptible to improvement. For example, the present inventors have determined that conventional garment-based hip protectors are uncomfortable and, accordingly, are less likely to be worn. The combination of tight garments and stiff pads can make conventional hip protectors difficult to get on and off, especially for elderly persons. The relatively stiff foam pads also tend to buckle outwardly, as a whole and into a somewhat arcuate shape, when the wearer moves from a standing position to a sitting position, which makes sitting uncomfortable. Additionally, pads with hard shell covers do not breathe and can trap heat between the hard shell cover and the skin, which can cause the wearer to sweat. An improperly placed pad with a hard shell cover can also actually increase the likelihood of injury from a fall.
- A hip protector in accordance with at least one of the present inventions includes right and left pad assemblies, which each include a plurality of elongate pads that define respective anterior and posterior ends, extend in anterior-posterior directions, and are spaced from one another in a superior-inferior direction such that there is a gap between the anterior ends of adjacent elongate pads, and a garment on which the right and left pad assemblies are carried such that portions of the right and left pad assemblies respectively cover the right and left greater trochanters, the garment being configured to permit the size of the gap between the anterior ends of at least some of the adjacent elongate pads of the right and left pad assemblies to decrease as the wearer moves from a standing position to a sitting position.

This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the inventions.
- A hip protector in accordance with one embodiment of one of the present inventions is generally represented by
reference numeral 10 inFIGS. 1-3 . Thehip protector 10 includes awearable garment 100 and first andsecond pad assemblies 200. Thewearable garment 100 andpad assemblies 200 are respectively configured and positioned relative to one another such that thepad assemblies 200 will be located over, and centered relative to, the greater trochanters (whose locations are represented by the circled GT) in the manner illustrated inFIGS. 1-3 when the hip protector is worn. Thepad assemblies 200 are also formed from material (discussed below) that is flexible enough to comfortably wrap around the hip area when thehip protector 10 is worn. - The exemplary
wearable garment 100 includes apelvic portion 102, withhip regions crotch region 108, and a pair ofleg portions waist band 114 is connected to the top (or “superior”) end of thepelvic portion 102, andleg apertures leg portions leg portions wearable garment 100 also defines a front (or “anterior”)side 120 and a rear (or “posterior”)side 122, and thepelvic portion 102,leg portions waist band 114 have anterior and posterior sides. It should also be noted here that thewearable garment 100 is a loose fitting garment that is intended to be worn under clothing. - The
exemplary pad assemblies 200, which are identical in the illustrated implementation, each include a plurality ofelongate pads 202 that define respective anterior andposterior ends FIG. 4A ) in the illustrated implementation. Theelongate pads 202 extend generally in the anterior-posterior direction, i.e., the pads need not be parallel to one another and may be offset from the horizontal anterior-posterior direction by up to 12°. Theelongate pads 202 are also spaced apart from one another in the superior-inferior direction such that there is agap 208 between the anterior ends of adjacent elongate pads. There may also begaps 210 between theposterior ends 206. As used herein in the context of theelongate pads 202, two elongate pads are both “adjacent” to one another and separated by a gap when the two elongate pads face one another with no other elongate pad (or resiliently pad material other than the optionalthin border 218 that occupies a portion of the gap) between the two pads. In those instances where the magnitudes of thegaps 208 vary in the anterior-posterior direction, the distance between theanterior ends 204 ofadjacent pads 202 will be greater that the distance between theposterior ends 206. - The
exemplary pad assemblies 200 also each include aconnector pad 212 that extends in the inferior-superior direction. Theconnector pad 212 provides additional coverage for the greater trochanter and simplifies the manufacturing process (as compared to a pad assembly without the connector pad). Theconnector pads 212 include portions of the associatedelongate pads 202. In other implementations, theconnector pads 212 may be omitted, as is discussed below with reference toFIGS. 10 and 11 . - As noted above, the
exemplary pad assemblies 200 comfortably curve around the hip areas. To that end, and referring toFIGS. 4A and 5A , theelongate pads 202 may include regions of increased flexibility (relative to the remainder of the elongate pads) 214 that, in the illustrated implementation, are located in the middle regions of the pads. The regions of increasedflexibility 214 create hinge points where the elongate pads can more easily bend. When thehip protector 10 is worn in its intended manner, the regions of increasedflexibility 214 will be immediately anterior of the greater trochanter. The increased flexibility is created by reducing the thickness of the resilient material which forms theelongate pads 202. Alternatively, the increased flexibility may be accomplished by, for example, forming the pads from two or more pieces that are connected to one another with a thin piece of material. It should also be noted that the regions of increasedflexibility 214 extend in a direction that is transverse to, and not perpendicular to, the longitudinal axis LA of theelongate pads 202, which helps the elongate pads fold and wrap around the thigh when the wearer is in both the standing position and the sitting position. The regions of increasedflexibility 214 may also be omitted in other implementations. - Additionally, as discussed in greater detail below with references to
FIGS. 7 and 8 , theexemplary hip protector 10 is configured in such a manner that elongatepads 202 will move relative to one another (i.e., bend, twist, bunch up or otherwise articulate relative to one another) so that thepad assemblies 200 can compress, without substantial bulging, as the wearer moves from a standing position to a sitting position. The aforementioned regions of increasedflexibility 214 are one aspect of thepad assemblies 200 that augment this functionality. Referring toFIG. 4A , relative movement of theelongate pads 202 may be further augment by regions of increasedflexibility 216 located in portions of theconnector pad 212 that are between theelongate pads 202. Here too, the regions of increasedflexibility 216 may be created by reducing the thickness of the resilient material which forms theconnector pads 212 or by, for example, forming the pads from two or more pieces that are connected to one another with a thin piece of material. - Each
exemplary pad assembly 200 also includes athin border 218 that extends around the perimeter of the pad assembly, including inwardly and outwardly between adjacentelongate pads 202. Theborder 218 occupies portions of thegaps 208 and all of thegaps 210. The border facilitates attachment of thepad assemblies 200 to thegarment 100 by way of techniques such as heat sealing and sewing. - Referring to
FIGS. 4A-6 , the anterior and posterior ends 204 and 206 and thesides 220 and 222 of thepads 202 may be slanted (as shown), rounded or otherwise contoured in order to reduce the visibility of thepad assemblies 200 through an outer garment that is worn over thehip protector 10. The portions of theconnector pad 212 that are between theelongate pads 202 may be similarly contoured. - With respect to materials, the
garment 100 may be formed from materials that are commonly used in loose fitting garments such as, for example, cotton, polyester, and cotton and spandex blend (less than 10% spandex), polyester and spandex blend (less than 10% spandex) and cotton, polyester and spandex blends (less than 10% spandex). Thepad assemblies 200 may be formed from any material that provides the desired level of impact protection. Suitable materials include, but are not limited to, foams and elastomers, including smart foams that harden on impact such as those sold under the tradename D3O®. Bladders filled with air and viscoelastic fluids may also be employed. In the illustrated implementation, a thin layer of low friction material 224 (FIG. 5B ), such as polyester fabric with an outermost layer of thermoplastic polyurethane (TPU) that acts as a bonding agent, is secured to the top surfaces of thepads border 218. Thelow friction material 224 allows the wearer's pants or other outer garment to move freely relative to the pad assemblies. - The
pad assemblies 200 may be secured to, or otherwise carried by, thegarment 100 in a variety of ways. Thepad assemblies 200 may be permanently affixed to thegarment 100 through techniques such as gluing, bonding, heat sealing, and sewing. Alternatively the pads may be removable from thegarment 100 and, for example, carried within pockets on the garment. In those embodiments where theconnector pads 212 have been omitted (e.g.,FIGS. 10 and 11 ), the elongate pads may affixed to a substrate, such as a fabric sheet or plastic sheet, so that the pads may be placed into the garment (and removed from the garment) as a single unit. In either case, thepad assemblies 200 may be located on the exterior surface of the garment (as shown), which faces away from the wearer, or the interior surface. - Turning to the dimensions of the
exemplary pad assembly 200, and referring toFIG. 4B , the overall size of the pad assembly (less the border 218) is about 6.25 inches in the anterior-posterior (AP) direction and is about 8.5 inched in the superior-inferior (SI) direction. With respect to the elongate pads 202 (from theanterior end 204 to posterior end 206), the lengths L1 to L5 of the elongate pads 202-1 to 202-5 are respectively about 3.8 inches, about 5.3 inches, about 6.1 inches, about 6.1 inches and about 4.5 inches. The widths W1 to W5 of the elongate pads 202-1 to 202-5, measured perpendicularly to the longitudinal axis LA (FIG. 4A ) are respectively about 1.0 inch, 1.25 inches, 1.25 inches, 1.25 inches, and 1.0 inch. Thegaps 208 are large enough to permit relative movement of adjacentelongate pads 202, but small enough to ensure that impact forces are spread across the top of thepad assemblies 200 during a fall. To that end, the distances D1 to D4 between adjacentelongate pads 202 are about 1.1 inches, 1.25 inches, 1.25 inches and 1.25 inches, respectively. Turning toFIG. 4A , the angles Θ1 to Θ1 are between adjacentelongate pads 202 are about 10°, 10°, 9° and 10°, respectively. It should also be noted that, as used herein, the term “about” means±10%, and that the pad assemblies in accordance with the present inventions are not limited to the exemplary dimensions. - As illustrated for example in
FIGS. 7 and 8 , both thepad assemblies 200 of thehip protector 10 are compressed in a manner that is more comfortable for the wearer (as compared to conventional hip protectors) when the wearer moves to a sitting position with the hip protector worn under an outer garment (e.g., pants). For example, the distance between the anterior ends 204 of theelongate pads 202 decreases and the anterior ends of adjacent pads are pushed into thegaps 208 toward one another. The loose fitting garment material within thegaps 208 betweenadjacent pads 202 simply folds. Portions of theelongate pads 202 may also twist about, for example, their longitudinal axis LA (FIG. 4A ). Theconnector pads 212 also bend to accommodate movement into the sitting position. As a result, thepad assemblies 200 compress, i.e., the size of the outer perimeter decreases, instead of bulging when the wearer moves to the sitting position. Put other way, thepad assemblies 200 compress in a manner similar to a typical pair of pants when the wearer moves from the standing to sitting position. - It should be noted here that, due to the loose fitting properties of the
garment 100 and the relative stiffness of thepad assemblies 200, the pad assemblies will not compress in the manner illustrated inFIGS. 7 and 8 (or will only compress slightly) unless thehip protector 10 is worn under an outer garment that holds thepad assemblies 200 against the wearers body. To that end, and referring toFIG. 8A , the looseness of the garment pelvic andleg portions pad assemblies 200 to move slightly relative to the wearer and relative to thetight waistband 114. - Another advantage of the
present hip protector 10 is associated with the shape of thepad assemblies 200. To that end, and referring toFIG. 9 , thepresent pad assemblies 200 cover more area in the superior-inferior direction than a circularly-shaped pad (represented by dashed line CSP) that is the same size in the anterior-posterior direction. As a result, thepresent pad assemblies 200 can better accommodate movement of the pads during use and wearers with the same waist size and differences in other anatomical aspects, such as waist to crotch distance. - Another exemplary pad assembly, which is generally represented by
reference numeral 200 a inFIGS. 10 and 11 , is substantially similar topad assembly 200 and similar elements are represented by similar reference numerals. To that end,pad assembly 200 a includes a plurality ofelongate pads 202 a, having anterior and posterior ends 204 a and 206 a,gaps 208 a between the anterior ends, andgaps 210 a between the posterior ends. Athin border 218 a extends around the perimeter of the pad assembly and between adjacentelongate pads 202 a. A pair of thepad assembly 200 a may be incorporated into a garment, such as thegarment 100, to form a hip protector. In contrast to thepad assemblies 200, thepad assemblies 200 a do not include a connector pad that extends in the inferior-superior direction. Theelongate pads 202 a also have an oval shape, as opposed to the more rectangular shape of thepads 202, and there are four elongate pads in thepad assembly 200 a, as opposed to five in thepad assembly 200. - Although the present inventions have been described in terms of the preferred embodiments above, numerous modifications and/or additions to the above-described preferred embodiments would be readily apparent to one skilled in the art. By way of example, but not limitation, hip protectors may include pad assemblies that are not identical to one another. It is intended that the scope of the present inventions extends to all such modifications and/or additions.
