Abstract:
A seat back structure includes a web extending about a central opening, and an inner flange extending about an inner perimeter of the web adjacent to the central opening. The seat back structure also includes an outer flange extending about an outer perimeter of the web. The inner flange, the outer flange and the web form a channel extending about the seat back structure, and the seat back structure is formed from a single piece of material.
Abstract:
A method of locally heat treating a structural member (346) for a vehicle component, comprising placing the structural member into a fixture including a first element (761) having a first layer that is electrically conductive and a second element (762) having a first layer that is electrically conductive; moving at least one of the first and second elements into contact with the structural member; imparting a pressure into the structural member by at least one of the first and second elements; passing a current through the electrically conductive first layers of the first and second elements to effect at least one heat treated area in the structural member; and stopping the current and releasing the pressure from the structural member.
