Abstract
A load-distribution insert configured to connect two shoulder straps of a backpack, weighted vest, or similar device. The insert includes a flexible body that expands laterally to distribute load across a user's shoulders and accommodate variations in shoulder width. In some embodiments, the lower layer includes folded ventilation channels. In others, a rigid control piece limits maximum expansion. A retrofit kit embodiment includes attachment mechanisms allowing installation onto existing straps without sewing.
Claims19
An apparatus for distributing load between dual carrying straps, the apparatus comprising:
- a flexible body configured to connect a first carrying strap and a second carrying strap, the flexible body being laterally expandable to dynamically adjust a separation distance between the straps during use;
- and a rigid control piece coupled to the flexible body, the rigid control piece being substantially inelastic and having a fixed length that defines a maximum lateral expansion of the flexible body, wherein the rigid control piece limits over-elongation of the flexible body when the first and second carrying straps are simultaneously lifted for use as a handle.
An apparatus for distributing load between dual carrying straps comprising a flexible body configured to connect a first carrying strap and a second carrying strap, the flexible body being laterally expandable to dynamically adjust a separation distance between the straps and distribute load across a broader area of a user's shoulders,
- wherein the apparatus does not include a rigid control piece.
A retrofit kit for external attachment to two independent shoulder straps of a pre-existing load-carrying device, the kit comprising:
- a flexible connector body configured to span a user's upper back;
- and
- a first attachment mechanism and a second attachment mechanism disposed on opposing lateral sides of the flexible connector body;
- wherein the first and second attachment mechanisms are configured to detachably receive and retain the two independent shoulder straps, respectively, thereby externally coupling the retrofit kit to the pre-existing load-carrying device without permanent modification.
