Back-supported load-carrying mechanism with suspension-mounted pivoting lumbar support

Abstract

A back-supported load-carrying mechanism that includes a rigid frame having a lower portion that includes an opening between a first vertical side and a second vertical side. A horizontal shaft is mounted to the sides and extends through the opening. A lumbar support element is pivotally mounted on the horizontal shaft. The horizontal shaft is mounted to the vertical sides of the frame with a suspension mechanism that enables each end of the horizontal shaft (and each side of the lumbar support element) to move fore and aft in relation to the frame. Tensioners mounted on the frame apply forward pressure to the shaft. Two rear leg extensions on each side of the frame enable the load-carrying mechanism to stand upright when placed on the ground. The lumbar support can pivot approximately 95 degrees to a position enabling the load-carrying mechanism to be utilized as a chair.
