Embodiment Construction

[0054] The object of compacting the energy absorbing member and efficiently absorbing side impact energy is achieved by the following configuration: a side body structure of a vehicle including a center pillar whose lower end side is positioned outside the upper end in the vehicle width direction. The center pillar has a bending inducing portion provided at the lower portion of the outer wall of the center pillar and causing bending during a side collision, and a step-down portion provided at the corner of the outer wall of the center pillar of the bending inducing portion, An energy absorbing member is disposed between the step-down portion and the inner panel.

[0055] 【Example】

[0056] An embodiment of the present invention will be described in detail based on the following drawings.

[0057] The accompanying drawings show the side body structure of the vehicle, figure 1 It is a side view showing the side body structure of the vehicle viewed from the outside in the vehic...

Abstract

The purpose of the present invention is to provide a side vehicle body structure for a vehicle. The side vehicle body structure is capable of efficiently absorbing side impact energy while reducing the size of an energy-absorbing member, and is characterized by being provided with a center pillar (35), the lower end side of which is positioned at the outside in the vehicle width direction with respect to the upper end, and the center pillar (35) is provided with a bending-inducing section (36) that is provided at the lower portion of the outer side wall (35c) of the center pillar (35) and induces bending during a side collision, and a stepped downward portion (35f) provided at a corner portion of the center pillar outer side wall (35c) of the bend-inducing portion (36). An energy-absorbingmember (50) is disposed between the stepped downward portion (35f) and an inner panel.

Description

technical field [0001] The present invention relates to a side body structure of a vehicle including a center pillar whose lower end side is located on the outer side in the vehicle width direction relative to the upper end. Background technique [0002] Generally speaking, when the vehicle is viewed from the front, the lower end of the center pillar is located outside the upper end of the center pillar in the vehicle width direction. If a load is input to the middle part of the center pillar in the vertical direction during a side collision, the middle part of the center pillar will enter the interior of the vehicle compartment. the behavior of. [0003] In order to prevent this, there is known a technique of temporarily bending the lower side of the center pillar at the time of a side collision to make the center pillar vertical. [0004] Patent Document 1 discloses that a center pillar portion composed of an outer member and an inner member is provided, and a bending ind...
