Abstract

A load support system for carrying a load on a user'"'"'s back includes a load support, first and second user engaging surfaces, and first and second arms extending between the load support and the first and second user-engaging surfaces, respectively. The load support includes a back panel configured to extend substantially parallel to the user'"'"'s mid-coronal plane when worn. The first and second user-engaging surfaces are configured to engage the user on opposite sides of the user'"'"'s mid-sagital plane when worn. The first and second arms are coupled to the back panel at first and second spaced locations along a first axis on opposite sides of the user'"'"'s mid-sagital plane. The first arm has a first end pivotably coupled to the back panel about a second axis oblique to the first axis and oblique to a transverse plane of the user. The first arm further includes a second end coupled to the first user-engaging surface. The second arm has a third end pivotably coupled to the back panel about a third axis oblique to the first axis and oblique to the transverse plane of the user. The second arm further includes a fourth end coupled to the second user-engaging surface. In one exemplary embodiment, the load support system includes a body coupled to the back panel, wherein the first and third ends of the first and third arms are pivotably coupled to the body.
