Problems solved by technology

[0006] When a load such as an impact is applied to the pillar from its side, it is difficult to deform the pillar in a desired deformation mode, and in some cases the impact energy cannot be effectively absorbed

Embodiment Construction

[0030] First, refer to Figure 1~3 The pillar structure of the first embodiment of the present invention will be explained.

[0031] In the drawings, an arrow FR indicates the forward direction of the vehicle, an arrow UP indicates the upward direction of the vehicle, and an arrow IN indicates the inward direction of the vehicle width.

[0032] Such as figure 1 As shown, the pillar structure of the present embodiment is applied to each of the left and right center pillars 12 of the vehicle 10 . The upper end 12A of each center pillar 12 is connected to the roof side rails 14 , while the lower end 12B of the center pillar 12 is connected to the rocker 16 . The middle pillar 12 is casted from light alloy (such as aluminum alloy and magnesium alloy).

[0033] Above the substantially middle part of the middle support 12 (in the figure 1 The upper portion 12D of the center pillar 12 whose position is indicated by a dotted line) is integrated with the rib 30 in its open section ...

Abstract

A lightweight pillar structure having high absorbing effect of impact energy is provided. A center pillar (12) made of a light alloy is formed of a pillar body (20) and a functional part mounting portion (22) integrally formed together. The functional part mounting portion (22) is a cylindrical hollow boss, and a slide rail (126) is mounted to a thread portion formed in an inner periphery of the cylindrical hollow boss. The slide rail (126) is formed so as not to project from an inner side face of a center pillar (12) of a passenger compartment inward of the passenger compartment. Ribs (30) as deformation control means are integrally formed on an upper portion (12D) of the center pillar (12). The ribs (30) control a deformation mode of the center pillar (12) against side impact.

Description

technical field [0001] The present invention relates to strut structures, and more particularly to strut structures applied to automobile bodies. Background technique [0002] Fig. 20 shows an example of a strut structure applied to an automobile body (WO92 / 11158). [0003] Center strut 70 is made of extruded or cast material. The center strut 70 is provided with parts 72, 74, 76, 78, 80 and 82 whose heights are cut to differ segment by segment from each other. [0004] In the above-mentioned structure, the number of parts constituting the pillar increases, and thus the weight of the pillar itself disadvantageously increases. When functional parts (such as shoulder strap anchors) are installed on the central post 70, it is necessary to secure the mounting means (such as brackets) to support the functional part on the central post 70 by welding or the like. The result is a further increase in the number of parts and an increase in their mass. [0005] EP0836983A2 disclose...
