Abstract: A frame assembly for a vehicle seat includes a seat-supporting section and a back-supporting section which are joined in a manner which accommodates the attachment thereto of a seat belt assembly so that the seat belt assembly need not be attached to the body of the vehicle within which the seat is used in order to pass load test requirements. The seat-supporting section includes two elongated side members which are fixedly secured to one another in a substantially parallel relationship, and the back-supporting section includes a generally vertically-oriented beam disposed on one side of the seat and a brace for stabilizing the beam in its vertical orientation. The frame also includes gusset members for joining the back-supporting section to the seat-supporting section at the corners of the frame.
