[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile seat belt anchor mounting structure in which a seat belt anchor is mounted near the front of a storage recess for storing a spare tire.

[0002]

2. Description of the Related Art The seat belt anchor mounting structure described above includes:
Conventionally, there is one disclosed in Japanese Utility Model Laid-Open Publication No. 61-131378. According to this, a circular storage recess for storing a spare tire is formed in a rear floor panel of an automobile, and an anchor for a seat belt is attached near a front portion of the storage recess. Further, a reinforcing panel is welded to the front portion of the storage recess at a plurality of locations, and both ends of the reinforcing member extend to the left and right side members and are fixed to the side members. The part is reinforced.

[0003]

In the above construction, when a reinforcing panel is welded to the front part of the storage recess, it is required that the two parts be joined to each other at each part to be welded. However, as described above, the storage recess is circular in a plan view, and the vertical wall at the front is arc-shaped. Therefore, it is not easy to perform surface joining of the reinforcing panel to a plurality of predetermined locations. Therefore, in the above-described conventional configuration, the welding work of the reinforcing panel may be complicated. In addition, the reinforcing panel is extended to the left and right side members, and the reinforcing panel is large. Therefore, there is a disadvantage that the mounting structure of the anchor becomes complicated.

[0004]

The purpose of the present invention is to pay attention to the above-mentioned circumstances, and to facilitate the welding operation of the reinforcing panel to the front portion of the storage recess and have sufficient anchor mounting strength. However, an object of the present invention is to provide a seat belt anchor mounting structure for a vehicle having a simple structure.

[0005]

A feature of the present invention for achieving the above object is that a vertical wall at the front of a storage recess formed in a rear floor panel is formed in a polygonal shape in a plan view, The combined structure of the front portion of the concave portion and the reinforcing panel welded to the front portion of the storage concave portion has a box-shaped closed cross section in a side view and a front view.

[0006]

[Operation] The operation of the above configuration is as follows. The front vertical wall (vertical wall) 9a at the front of the storage recess 7 is formed in a polygonal shape in plan view. For this reason, when the reinforcing panel 15 is to be welded to the front part of the storage recess 7, the surface joint of the welded portion is a surface joint between flat surfaces. Therefore, conventionally, in the above-mentioned welded portion, it was necessary to surface-bond a reinforcing panel to the front portion of the arc-shaped storage recess, and the welding operation was complicated, but according to the present invention, ,
Surface joining is facilitated, and as a result, the work of welding the reinforcing panel 15 to the front portion of the storage recess 7 can be easily performed.

A combined body 16 formed by a front portion of the storage recess 7 and a reinforcing panel 15 welded to the front of the storage recess 7 has a box-shaped closed cross section in a side view and a front view. . Therefore, the reinforcing panel 15 has sufficient rigidity. Therefore, the mounting strength of the anchor 11 attached near the front portion of the storage recess 7 is sufficiently improved by the rigidity of the coupling body 16.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 denotes an automobile body,
The vehicle body 1 is symmetrical with respect to the vehicle center line 2. The arrow Fr in the figure indicates the front of the automobile.
A rear portion of the vehicle body floor constituting the vehicle body 1 is formed by a sheet metal rear floor panel 3, and side members 4 are fixed to lower surfaces on both left and right sides of the rear floor panel 3, respectively.

A storage recess 7 for storing a spare tire 6 is formed at the rear of the rear floor panel 3 between the left and right side members 4. The storage recess 7 includes a flat bottom plate 8 on which the spare tire 6 is mounted, and a vertical wall 9 surrounding the spare tire 6 from above in the horizontal direction.
This vertical wall 9 is a front vertical wall 9a corresponding to the front portion of the bottom plate 8.
And side vertical walls 9b, 9b extending substantially linearly rearward from the left and right ends of the front vertical wall 9a, and these side vertical walls 9b,
A rear vertical wall 9c connects the rear ends 9b substantially linearly. Each part of the vertical wall 9 is inclined upward as it goes away from the bottom plate 8 in the horizontal direction.

A seat 10 is provided in front of the front vertical wall 9a, and the seat 10 is erected corresponding to a seat cushion 10a supported on the rear floor panel 3 and a rear end of the seat cushion 10a. Seat back 10
b. In the vicinity of the front of the front vertical wall 9a, four anchors 11 are attached by bolts 12 at substantially equal intervals on the left and right sides, and three anchors 13 are supported by these anchors 11. Each of these seat belts 13 is connected to the seat cushion 10 a and the seat back 10.
b and extends forward through the seat cushion 10
a.

The front vertical wall 9a and a sheet metal reinforcing panel 15 facing the general portion 3a of the rear floor panel 3 connected to the front vertical wall 9a from the lower surface side are provided, and the reinforcing panel 15 expands downward. A protruding portion 15a, a front flange 15b formed at a front edge of the protruding portion 15a,
It is composed of a rear flange 15c formed on the rear edge and side flanges 15d formed on the left and right side edges. The general portion 3a and the front flange 15b of the rear floor panel 3 are surface-welded and spot-welded (hereinafter simply referred to as "welding") at a plurality of places. In this case, the bolt 12 tightens the front flange 15b together with the general portion 3a of the rear floor panel 3 to reinforce the connection between the general portion 3a of the rear floor panel 3 and the front flange 15b.

The front vertical wall 9a is formed in a polygon having three sides in plan view. On the other hand, the rear flange 15c also has a polygonal shape that matches the front vertical wall 9a, and the flat surfaces of the front vertical wall 9a and the rear flange 15c are surface-welded and welded to each other at a plurality of locations. Further, the flat surface of the general portion 3a, the front vertical wall 9a, and the flat surface of the side flange 15d are surface-joined and welded to each other at a plurality of locations.

As a result, as shown in FIG. 2, the combined body 16 formed by the front portion of the storage recess 7 and the reinforcing panel 15 welded to the front portion of the storage recess 7 as described above is a box. It has a closed cross section. Further, as shown in FIG. 3, the box-shaped closed cross section is also seen from the front. For this reason, since the coupling body 16 has sufficient rigidity, the anchor 11
Has sufficient mounting strength. The left and right dimensions of the coupling body 16 are substantially the same as the left and right dimensions of the storage recess 7. Therefore, when an external force directed forward is applied to the anchor 11 via the seat belt 13, The external force is supported by the coupling body 16 and is also strongly supported by the side vertical wall 9b of the rigid storage recess 7.

FIG. 4 shows another embodiment. According to this, the front vertical wall 9a is a polygon having two sides. Other configurations and operations are the same as those of the above embodiment. In addition,
The front vertical wall 9a may be a polygon having four sides or five sides.

[0015]

According to the invention, since the vertical wall at the front of the storage recess is formed in a polygonal shape in a plan view, when the reinforcing panel is to be welded to the front of the storage recess, the same is applied. The surface joining of the welded portion is a surface joining of flat surfaces.
Since the flat surfaces are relatively easily joined to each other, the work of welding the reinforcing panel to the front portion of the storage recess can be easily performed.

[0016] Further, since the joined body formed by the front part of the storage recess and the reinforcing panel welded to the front part of the storage recess has a box-shaped closed cross section in a side view and a front view, respectively.
The reinforcing panel will have sufficient rigidity. Therefore, the mounting strength of the anchor attached near the front portion of the storage recess is sufficiently improved by the rigidity of the coupling body.
Moreover, the reinforcing panel has sufficient rigidity without extending to the side members as in the related art.
Since it is sufficient to have a small shape corresponding to the front part of the storage recess, there is an advantage that the mounting structure of the anchor is correspondingly simplified.
