STRUCTURE FOR CONTROLLING DEFORMATION OF SIDE STRUCTURE OF CAR BODY

摘要

PROBLEM TO BE SOLVED: To provide a frame which can favorably absorb a side collision in a new car body without a conventional B pillar. SOLUTION: The frame and supporting assembly of a vehicle without a conventional separate B pillar are equipped with first and second frame members and a plurality of supporting assemblies. Each supporting assembly is equipped with a plurality of bulkheads, a pair of outriggers and a cross member. The bulkhead is internally provided in first and second side sill assemblies. The outrigger extends between the side sill assembly and the first and second frame members. The cross member extends between the first and second frame members. Strengths of the bulkhead, the outrigger and the cross member are selected in such a manner that the rigidity of the cross member may become higher than that of the outrigger. The rigidity of the outrigger is higher than that of the bulkhead so that the supporting assemblies may gradually be crushed at the time of a side collision. COPYRIGHT: (C)2005,JPO&NCIPI
