Patent attributes
A suspended load backpack includes a moving frame including a bag for receiving a load to be carried by the backpack, a fixed frame including shoulder straps for holding the fixed frame in place on a wearer's back, and a rail assembly that connects the moving frame to the fixed frame but allows the moving frame to move relative to the fixed frame. A mounting wheel is connected to the fixed frame, and a compliant mechanism such as a bungee cord is connected between the fixed frame and the moving frame and wrapped around the mounting wheel to permit movement of the moving frame relative to the fixed frame during a gait of the wearer of the backpack in accordance with tension on the compliant mechanism. A ratchet assembly includes a lever that rotates the mounting wheel to easily apply tension to the compliant mechanism.
