PCT No. PCT/EP92/00554 Sec. 371 Date Sep. 24, 1993 Sec. 102(e) Date Sep. 24, 1993 PCT Filed Mar. 13, 1992 PCT Pub. No. WO92/18369 PCT Pub. Date Oct. 29, 1992A rear support structure for the coachwork of a passenger vehicle having closed loop interconnected frame members including a longitudinally extending bottom sill connected at its rearward portion to the forward portion of a rear wheel housing carrier member. The rearward portion of the rear wheel housing carrier member is connected to at least one roof support post which in turn is connected to the roof structure. The connection of the sill to the rear wheel housing carrier member is at a low angle, providing resistance to mechanical fatigue due to flexing and vibration, while at the same time providing a rear passenger door cutout of sufficient size to permit easy entry and egress of rear passengers. The rear wheel housing carrier member has at least two, approximately linear regions, one arcuately flowing into the other for connection of the vehicle's floor structure and two roof support posts of the vehicle bodywork. In the preferred embodiment, the rear wheel carrier member has three approximately linear regions joined by two intermediate arcuate sections. The interconnection of the bottom sill, the rear wheel carrier member, the roof support post, and the roof structure provides a rigid rear bearing structure having a continuous force flux pathway, which dissipates the energy of a side collision thus protecting passengers in the event of such a collision with the rear passenger compartment. |
