Patent number: 6863338Abstract: So that intake water cannot flow from a frame side member of the body structure by way of a seat cross member into an exterior side member of the vehicle, a so-called partition part is arranged between the frame side member and the seat cross member, which partition part comprises a basic part and an expansion foam arranged thereon. As a result of the effect of heat, the expansion foam can expand to such an extent that the passage surface in the seat cross member is closed off in a watertight fashion and water can no longer enter the cross member.Type: GrantFiled: August 20, 2003Date of Patent: March 8, 2005Assignee: Dr. Ing. h.c.F.

Patent number: 6851740Abstract: An automotive vehicle having a passenger cabin includes a floorpan with seats mounted to the floorpan. Side closure structures adjoin the outboard ends of the seats. Seat displacement members located within the side closure structures load the outboard ends of the seats so as to deform the seat frames and floorpan. This moves the affected seat laterally inward with respect to a longitudinal center plane of the vehicle in the event of a laterally directed impact load against the closure structure. As a result, the pelvic region of the occupant will be the first region of the occupant to be dynamically loaded by the side closure structure.Type: GrantFiled: October 24, 2003Date of Patent: February 8, 2005Assignee: Ford Global Technologies, LLCInventor: James Zheng Peng

Publication number: 20040256889Abstract: A method of manufacturing a vehicle body part embeds an insert piece into a foamed layer of the body part by holding the insert piece in a foaming tool using a magnetic force. The magnetic force holds the insert piece into position, eliminating the need for any additional holding structures in the foaming tool. A body part made by this method has improved visual quality, particularly at a transition area between the insert piece and a decorative part.Type: ApplicationFiled: June 23, 2004Publication date: December 23, 2004Inventors: Horst Schonebeck, Matthias Ludwig, Marcus Lutz, Frank Niebuhr
