Abstract
A backpack with a self stabilizing shoulder strap system is disclosed. The backpack includes two shoulder straps, an intermediate member, and a bag. The bag is configured to pivot about a first connector associated with the intermediate member. The shoulder straps are configured to pivot about connectors associated with the intermediate member. The configuration of the shoulder strap system allows for the bag to remain substantially vertical during motions as the shoulders are raised and lowered.
