International Classification:

A45F 304

US Classification:

224637, 224631, 224632, 224634, 224635, 224641

Abstract:

A back-mounted load-carrying device, such as a backpack or a child carrier, having an adjustable waist belt assembly is described. The waist belt assembly is freely slidable between a variety of vertical positions along a rigid frame. A locking mechanism, actuatable while the device is being worn, permits a user to adjust the waist belt assembly to rest comfortably on his hip and around his waist on the fly and subsequently secure the waist belt in the desired position. A pair of hip-load transfer members that are rigid to loads applied in the vertical direction comprise the waist belt assembly and rest against the hip of a user when the waist belt is secured. These members help to transfer load from the device to the users hips and act to lessen the amount of load carried by the users shoulder and back, the result being greater comfort and less fatigue.
