ABSTRACT:
An improved pan cushioning frame for a vehicle seat is disclosed. The frame comprises separately-formed two side frames and a center panel. The side frames are made of steel plate which is thicker than that for the center panel. The three parts are connected together to form the pan cushioning frame. According to the invention, the frame thickness and form can be selected depending on load to be applied thereto, and it requires no additional reinforcing members. Further, the frame will not be over-strong since too thick plate is not used.
