の間に一体に溶接結合されている。 Inside the rear quarter pillar 10 and inside the inner panel 11, a first reinforcing member 14 having a substantially U-shaped cross section and flanges on both sides is arranged vertically with its opening facing the inner panel 11 side. The reinforcing member 14 and the inner panel 11 are welded at appropriate locations. The lower end 14a of the first reinforcing member 14 is welded to the wheel arch portion 13, and the upper end 14b is connected to the rear flanges 11b, 12b of the rear quarter pillar 10.

As shown in Figure 4, the front and rear flanges 11a, 12a and 11b, 12b of the rear quarter pillar 10, respectively.
are welded together in between. The intermediate portion of the second reinforcing member 15 is welded to the back surface of the intermediate portion of the first reinforcing member 14, and both reinforcing members 14 and 15 are integrally connected.

１４への補強効果が大きいからである。 In the above structure, the seat belt 16
When excessive tension is applied in the direction of the arrow in FIG.
A large bending stress acts on 4. However, the first
The reinforcing member 14 intersects with the second reinforcing member 15
Since the belt is reinforced by the belt, bending at the waist is restricted, and there is no risk of buckling as shown in Figure 1.
That is, since the second reinforcing member 15 is coupled to the middle part of the first reinforcing member 14 that is most likely to buckle, and this second reinforcing member 15 is provided to span the rear quarter pillar 10 in the front-rear direction,
This is because it has a structure in which both ends are supported, so to speak, and the effect of reinforcing the first reinforcing member 14 is large.
また、第２補強部材１５はリヤクオータピラー
１０に対し前後方向に設けられる関係上、そのス

格段に向上し、座屈するおそれがない。 Furthermore, because the second reinforcing member 15 is provided in the front-rear direction with respect to the rear quarter pillar 10, its span is short and its bending strength and compressive strength are large.
Therefore, due to the sum of the strength of the second reinforcing member 15 and the strength of the first reinforcing member 14 having a U-shaped cross section, the rigidity of the rear quarter pillar 10 is significantly improved compared to the conventional one, and there is no risk of buckling.
なお、第２補強部材１５を設けることによつ
て、第１補強部材１４にかかる負坦が軽減される
ため、この第１補強部材１４の肉厚を従来より薄
くし、軽量化することも可能である。 In addition, by providing the second reinforcing member 15, the load applied to the first reinforcing member 14 is reduced, so it is also possible to make the wall thickness of this first reinforcing member 14 thinner than before and to reduce the weight. It is.

て固定してもよい。 Although the above embodiment shows the case where the seat belt anchor 17 is attached to the first reinforcing member 14, the seat belt anchor 17 may be attached to the second reinforcing member 15. In this case, it is necessary to arrange the second reinforcing member 15 inside the inner panel 11. Further, the first reinforcing member 14 is not limited to being fixed with its opening side facing the inner panel 11, but may be fixed with its back side facing the inner panel 11, conversely.

である。Effects of the invention As is clear from the above explanation, according to the invention, reinforcing members are arranged inside the rear quarter pillar in a manner that intersects vertically and horizontally, so that the load acting on the seat belt anchor is received by both reinforcing members. So,
Even if an excessive force is applied to the seat belt anchor as in the case of a collision, the reinforcing member does not buckle, so there is no risk of the rear quarter pillar buckling, making it safe.
