Body structure for motor vehicle

摘要

A motor vehicle having a continuous closed cross sectional structure therearound. The vehicle includes a center pillar and a side sill, both of which are connected with a doubler extended transversely. A center roof brace is connected with the upper end of the center pillar through a joint member. The outside end of the doubler is connected with the center pillar in such a manner that it laps the lower end of the center pillar. Further, the doubler is connected with a center tunnel which is reinforced from underneath. The center pillar, the doubler and the center roof brace have a closed cross section respectively. The center pillar includes a strength discontinuity portion at the lower portion thereof. In the event of a side impact, the center pillar yields toward the inside direction of the vehicle at the strength discontinuity portion without bending the upper portion thereof and the amount of deformation of the center pillar is controlled.
