Abstract
Abstract The backpack carrier permits a user to bend sideways, forward and backward without impediment. It includes a backpack frame and shoulder harness which is pivotally attached to a hip yoke through a two axis pivot member to permit pivotal movement therebetween about the vertical axis and about the horizontal axis generally perpendicular to the plane defined by the backpack frame. The ends of the hip yoke are secured to a harness locatable about the user's waist through a pivot member to permit pivotal movement of the hip yoke about the horizontal axis in the plane generally defined by the backpack frame.
