The technology described herein relates generally to backpacks and, more specifically, to hip belt assemblies for backpacks.
Backpacks have long been used to carry heavy, bulky loads. Various configurations of backpacks exist, including packs having external frames, internal frames, and those without frames. Regardless of the type of backpack, backpacks often include a hip belt attached to a lower portion of the sack to facilitate in distributing the weight of the load onto a wearer in a desirable manner. A hip belt transfers some of the load onto the hips and lumbar area of a wearer, and can reduce the load applied to the user's shoulders, thus allowing the wearer to carry a heavy load in relative comfort.
Typically, a hip belt is attached to a lower portion of the backpack, extending about the hips of the wearer. Many hip belts include padding to add comfort on the wearer's hip and back, and buckles in the front to secure the hip belt around the wearer's waist. Many hip belts are rigidly attached to the backpack causing the weight of the backpack to shift as a wearer moves. A shifting load may cause overloading to concentrated areas on the wearer, and cause discomfort.
More recently, certain hip belts have been configured with mechanical adjustments to facilitate the relative movement between the sack and the hip belt. However, many of these mechanical adjustments do not allow the hip belt to move sufficiently relative to the sack of the backpack given the wearer's movements. Thus, as the wearer moves, the load still tends to shift an undesirable amount relative to the wearer's hips. Further, such mechanical attachments of the hip belt may be bulky, complex, and difficult to manufacture.
It is therefore desirable to provide an improved hip belt assembly, and, more specifically, to provide a simple and resilient hip belt assembly that can conform to a wearer's movements while providing effective load distribution.

Additional embodiments and features are set forth in part in the description that follows, and will become apparent to those skilled in the art upon examination of the specification or may be learned by the practice of the disclosed subject matter. A further understanding of the nature and advantages of the present disclosure may be realized by reference to the remaining portions of the specification and the drawings, which forms a part of this disclosure. One of skill in the art will understand that each of the various aspects and features of the disclosure may advantageously be used separately in some instances, or in combination with other aspects and features of the disclosure in other instances.
The description will be more fully understood with reference to the following figures in which components are not drawn to scale, which are presented as various examples of the present disclosure and should not be construed as a complete recitation of the scope of the disclosure, characterized in that:
This disclosure is related to a backpack with a flexible hip belt assembly. Depending on the embodiment, the backpack may include a cargo bag or sack, a frame assembly, a resilient panel, and a hip belt. The frame assembly may include a frame member, a back panel assembly, and a support panel. The back panel assembly may include several panels or layers, including a back panel and a suspension panel. In one embodiment, the hip belt is resiliently coupled to the frame assembly by the resilient panel. The resilient panel expands and contracts as the hip belt and frame assembly move relative to one another to reduce the forces applied to the hip belt by the non-vertical movement of the frame assembly.
In operation, the resilient panel at least in part couples the hip belt to the frame assembly to generally isolate the movement of the hip belt from the movement of the frame assembly. Since the hip belt engages a wearer's hip region, the hip belt moves with the wearer's hips. The frame assembly supports the cargo bag, which may include a cargo load of up to 50 or more pounds. The frame assembly then includes a load that creates a moment force generally about the attachment between the hip belt and the frame assembly. This cargo load moves, such as swaying, and has an associated momentum that can be transmitted through a traditional connection structure between a frame assembly and a hip belt, and then to the wearer, which can create undesirable effects. The connection structure between the hip belt and the frame assembly disclosed here, and, in particular, the resilient panels as used in this structure, allows the hip belt and frame assembly to move relative to each other to at least partially de-link the movement of the cargo load from the motion of the hip belt. This result is referred to herein as “hip belt flexibility.” This de-linking reduces the undesirable forces applied by the moving cargo load to a wearer through the hip belt. This provides advantages over traditional systems, such as, in one example, reduced energy consumption and increased comfort for a wearer. In addition, the resilient panel provides a simplified approach to improving hip belt flexibility that has functional and commercial advantages over the more complex existing systems.
Turning now to the figures, a backpack 100 with a flexible hip belt assembly of the present disclosure is shown in
The sack 160 is supported on the frame assembly 102, which may include a back panel assembly 104, a frame member 106, and a support panel 116. The back panel assembly 104 is positioned on the back side of the backpack 100, i.e. the side that faces a wearer's back. The back panel assembly 104 may be made up of one or more panels or layers. For example, the back panel assembly 104 may include one or more of a back panel 108, a foam layer 115, and a suspension panel 110. The back panel 108 is the panel closest to the front side of the backpack 100 in the back panel assembly 104. The back panel 108 may be of any shape that is compatible to engage with a wearer's back and support a sack for carrying cargo. For example, the back panel 108 may be an oval shape, a rectangular shape, or the like, and may be curved or flat. In this example, and as shown in
As shown in
The frame member 106 may be included in the frame assembly 102 to provide structural strength and rigidity to the back panel assembly 104. The frame member 106 may have a generally rectangular shape, and be positioned, as in this example, generally around the periphery of the back panel 108. The frame member 106, in this instance, provides the structural support for tensioning the suspension panel 110 so that it is taught, and spaced away from the back panel 108. The frame member may include one or more of a top support (not shown), a bottom support (not shown), a first side support 112 and a second side support 114. The frame member 106 may be any one of numerous frame structures, such as, for example, an external or internal frame. The frame member 106 may be made of plastic, metal wire, metal rods, or any other similar materials. It is also contemplated that the backpack 100 may be frameless. As shown in
The support panel 116, shown in
As shown in
The hip belt 122 is attached to the frame assembly 102 at a variety of locations to provide both vertical support for the cargo load, as well as the relatively independent rotational movement discussed above. The vertical support for the cargo load is provided by a fixed connection between the lower edge portion 156 of the hip belt 122 and the bottom portion of the frame assembly 102. A resilient attachment is provided by connecting a right and left resilient panel 118, 120 along portions of the right and left lateral portions 185, 184 of the central portion 124 and to the frame assembly 102, which is described in more detail below. As referred to herein, “vertical direction” means generally along a direction of the long length of the frame assembly (for example along a side edge portion 140, 142), “horizontally” or “lateral direction” means generally orthogonal to the direction of the long length of the frame assembly, and “non-vertical” means generally along a direction that includes a lateral component.
The hip belt 122 may be made of several layers. For example, the hip belt 122 may include at least one of a nylon layer for support, a foam layer for comfort, and a mesh layer for ventilation. In other embodiments, various other materials having sufficient structural strength and flexibility can be used, e.g., composites, e.g., glass-fiber composites; and plastics, e.g., thermoplastics and/or thermosets singly or in combination. It is also contemplated that the hip belt 122 is any existing belt used to support a load for one's back. For example, the hip belt 122 may be two straps that fasten together or it may be a padded structure with pockets.
The resilient attachment may include a plurality of resilient panels 118, 120, straps, or members at least partially coupling the hip belt 122 to the frame assembly 102. As shown in the embodiment in
As shown in
The resilient panels 118, 120 may be made of many types of stretchable, flexible, and/or elastic material that allows for rotation and flex, and is durable to withstand the forces applied between the frame assembly and the hip belt. For example, the resilient panels 118, 120 may be made of a fabric, mesh or webbing, an open mesh, or similar material having elastic properties. As one example, the resilient panels may be made of DS16-S54 Spiral Embo by Duck San Co., Ltd. The resilient panels 118, 120 may be stretch woven or knit or a fabric with mechanical stretch. The resilient panels 118, 120 have a rebound or memory characteristic that is configured to return entirely or substantially to an initial or pre-stretched position original position after being displaced by a force. The resilient panels may have a flat shape when in initial or pre-stretched position, or when under tension; or they may have other single or compound shapes, such as having a twist, buckle, crease, or the like. In one example, the resilient panel may include a lamina of more than one layer. For instance, the panel may include a top and bottom layer with an intermediate layer formed of monofilament elements. There may be more or fewer layers. Each layer of the lamina may be made of the same or different material, such as polyester, nylon, or similar.
The bottom panel 130, or load bearing panel, as shown in

With reference to
As shown in
The suspension panel 110 may be attached to at least an upper portion of the backpack 100. As shown, the first upper extended portion 111 of the suspension panel 110 is coupled to the first side edge portion 140 and the top edge portion 144 of the back panel 108 and may also be attached to the frame member 106. The second upper extended portion 113 of the suspension panel 110 is coupled to the second side edge portion 142 and the top edge portion 144 of the back panel 108 and may also be attached to the frame member 106. Alternatively, the suspension panel 110 may only attach to the frame member 106. In another embodiment, the suspension panel 110 or the upper extended portions 111, 113 may only attach to one edge portion of the back panel 108. The attachment of the suspension panel 110 to the backpack 100 places the suspension panel 110 in a suspended position, such that it is spaced away from back panel 108. In this position, the suspension panel 110 is taught and inextensible, such that when the suspension panel 110 is attached to the upper edge portion 154 of the hip belt 122, as discussed in more detail below, the tension runs from the top of the frame assembly 102, through the suspension panel 110, the hip belt 122, and the bottom panel 130, terminating at the engagement between the bottom panel 130 and the frame assembly 102.
As shown in
The resilient panels 118, 120 may be attached to a lower portion of the frame assembly 102. As shown in
The resilient panels 118, 120 further attach to the hip belt 122, such that the hip belt 122 is resiliently coupled to the backpack 100. Each of the resilient panels 118, 120 may attach to an adjacent lateral portion 185, 184 of the hip belt 122.
A cover panel 170, 171 may overlap and attach to a lower portion of each of the resilient panels 118, 120, as shown in
A portion of the hip belt 122 may also attach directly to a portion of the frame assembly 102. As shown in
The hip belt 122 is further attached to a lower portion of the frame assembly 102. The hip belt 122 may attach along a lower load bearing seam of the backpack 100 to support the load in the sack 160, primarily in a vertical direction. As shown in
As shown in
The bottom panel 130 may also attach to the frame assembly 102. For example, the bottom panel 130 may attach to a lower portion of the back panel 108. As shown in
The attachment of the hip belt 122 to the frame assembly 102 using the resilient panels 118, 120 as described herein allows the hip belt 122 to move relative to the frame assembly 102. The resilient panels 118, 120 expand and contract as the hip belt 122 and frame assembly 102 move relative to one another to reduce the forces applied to hip belt 122, and thus to the wearer, by the non-vertical movement of the frame assembly 102. The resilient panels may transition between a first, or initial, position or state and a second position or state. In the first position, the resilient panels may be under some or no tension. In the second position, the resilient panels are under tension, such as, for example, being stretched or rotated or twisted along a length, a width, or somewhere in between, such as, for example, in a diagonal direction.
The suspension panel 110 may provide additional freedom of motion to the resilient panels 118, 120 and hip belt 122. The attachment between the resilient panels 118, 120 and the suspension panel 110, and between the hip belt 122 and the suspension panel 110, allows the resilient panels 118, 120 and hip belt 122 to be spaced apart from the support panel 116 and the back panel 108. These attachments may allow for greater rotational movement. In addition, the suspension panel 110 provides added comfort and ventilation.
The fixed attachment of the hip belt 122 to the lower portion of the backpack 100 provides vertical load support in order to apply the weight carried in the sack 160 to the wearer's hips. For example, the attachment to the bottom panel 130 along the entire lower edge portion 156 of the central portion 124 of the hip belt 122 reduces or minimizes forces applied to the resilient panels 118, 120. Instead, some of the generally vertical load bearing force is transferred to the hip belt 122 through the attached bottom panel 130, or load-bearing panel. The combination of the resilient attachment of the upper portion of the hip belt 122 to the frame assembly 102 and the more rigid attachment of the lower portion of the hip belt 122 to the bottom panel 130 allows the hip belt 122 to rotate and/or twist with a wearer's body movements relative to the backpack 100 while the vertical load of the pack is largely supported vertically through the hip belt 122. This configuration of the hip belt 122 with the backpack 100 provides vertical stability while allowing for horizontal, and more generally non-vertical, flex capability. The motion of rotating may include at least a motion of translating and or pivoting in a curving manner about at least one point, and, for instance, may include at least partially moving in a vertical plane (for example, the plane of the frame assembly 102 shown in
Other embodiments for a backpack with a flexible hip belt are envisioned. As shown in the embodiment depicted in
In an alternate embodiment pertinent to both of the above examples, the resilient panels 118, 120, 314, 316 may be integrated with the frame assembly 102, 350, allowing for a resilient attachment point for hip belts of various shapes and sizes.
In other embodiments, the resilient panels 118, 120 may be in various configurations. For example, the resilient panels 118, 120 may be positioned along at least a portion of the upper edge portion 154 of the hip belt 122. There may be more than two resilient panels 118, 120 or one resilient panel, and the shapes and sizes may vary. For example, a single resilient panel may extend behind the hip belt 122 to both side edge portions 140, 142 of the frame assembly 102.
In additional embodiments, the back panel assembly 104 may include only the back panel 108. In this configuration, the resilient panels 118, 120 may attach directly to the back panel 108 instead of to the suspension panel 110 as depicted in the
The backpack 100, 300 may be formed from a variety of materials and means. For example, the frame assembly 102, 350, among others, may be formed from a thermoplastic material (self-reinforced or fiber reinforced), ABS, polycarbonate, polypropylene, polystyrene, PVC, polyamide, and/or PTFE, among others. In some examples, portions of the backpack 100, 300 may be extruded from aluminum or other similar metal. In addition, the frame assembly 102, 350 may be formed from fiber reinforced epoxy, resin, or other similar material. The backpack 100, 300 may be formed or molded in any suitable manner, such as by plug molding, blow molding, injection molding, extrusion, casting, or the like. The various components detailed above may be attached by various means, such as, for example, by stitching or sewing, or other mechanical fastening means; or by adhesive, bonding, sonic welding, heat taping, and other non-mechanical mechanisms to secure items together. The backpack 100, 300 may be formed from soft side material and/or hard side material. Exemplary materials are noted above.
All relative and directional references (including: upper, lower, upward, downward, left, right, leftward, rightward, top, bottom, side, above, below, front, middle, back, vertical, horizontal, and so forth) are given by way of example to aid the reader's understanding of the particular examples described herein. They should not be read to be requirements or limitations, particularly as to the position, orientation, or use unless specifically set forth in the claims. Connection references (e.g., attached, coupled, connected, joined, and the like) are to be construed broadly and may include intermediate members between a connection of elements and relative movement between elements.
