Abstract:
1. A method for producing a rear crossmember for a vehicle seat including the steps of: providing metal plate stock having a shape generally consistent with the rear crossmember to be produced, the plate stock further defined as having a first edge and a second edge; performing a simultaneous punching and clinching operation to locate and secure a plurality of threaded fasteners into the plate stock at predetermined points, said operation causing an opening to be punched through the plate stock and further causing the fasteners to be permanently retained in the plate stock at the openings such that the plurality of fasteners provides threaded connection points that are employed in the further construction of the vehicle seat; performing a rolling operation to cause the first edge of the plate stock to come into close proximity with the second edge of the plate stock in such a manner as to form the desired cross-sectional shape for the rear crossmember; performing a welding operation to secure the first edge to the second edge thereby forming the rolled plate stock into the desired rear crossmember; and performing a striking operation upon the metal plate stock to provide a plurality of notches and openings in the rear crossmember, which are employed in the further construction of the vehicle seat.
