[0001]

[Industrial applications]

 The present invention relates to an anchor plate for attaching a seat belt anchor to a pillar.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 6, there is a vehicle body 4 provided with a center pillar 3 for forming the door openings 1 and 2 by dividing the front and rear.

Further, as shown in FIG. 5 (A), such a center pillar 3 is formed in a hollow shape by aligning the front and rear edges of the inner plate 5 and the outer plate 6 with each other, and is formed in the inside 3 a thereof. There is one having a reinforcement plate 7 and an anchor plate 8 for mounting a seat belt anchor (not shown) (for example, JP-A-58-185375).

The reinforcement plate 7 is bent and formed in a crank shape in cross section so as to have flanges 7 a and 7 b extending in the front-rear direction of the vehicle body. The flange 7 a is formed on each of the flanges 5 a and 6 a of the inner plate 5 and the outer plate 6. The flange 7b is joined by spot welding in the sandwiched state, and the flange 7b is joined by spot welding in the sandwiched state by the respective flanges 5b, 6b of the inner plate 5 and the outer plate 6.

As shown in FIGS. 5 (A) and 4, the anchor plate 8 is joined to the inner wall surface 5 c of the inner plate 5 by spot welding in a close contact state, and at the same time, as a supporting means (anchor) for attaching a seat belt anchor. A nut 8), a flange 8b formed by bending an edge portion of the support portion 8a located on the front side of the vehicle body toward the outside of the vehicle body, and an edge portion of the support portion 8a located on the rear side of the vehicle body outside the vehicle body. A wall portion 8c that is bent toward and a flange portion 8d that is bent toward the rear of the vehicle body and that is continuous with the wall portion 8c are integrally formed.

The flange 8b is joined by spot welding to a wall portion 7c of the reinforcement plate 7 extending in the lateral direction of the vehicle body, and the flange 8d is joined by spot welding to a wall portion 7d of the reinforcement plate 7 extending in the vehicle longitudinal direction. .

Therefore, the center pillar 3 has a double structure in which the inner plate 5 and the outer plate 6 form a closed surface, and the reinforcement plate 7 and the anchor plate 8 form a closed surface. For example, it has a structure that secures strength against a load input to the center pillar 3 from a seat belt (not shown) via a seat belt anchor when a front collision of the vehicle body occurs.

The center pillar 3 is tilted so that the bent end of the wall portion 8c is displaced toward the front side of the vehicle body in order to set the width in the vehicle front-rear direction to be narrow.

[0009]

[Problems to be solved by the device]

 By the way, in the anchor plate 8 configured as described above, there are two points on the surface (the inner wall surface 5c and the wall portion 7d) along the front and rear direction of the vehicle body and one on the surface (the wall portion 7c) along the vehicle body left-right direction. Since the center pillar 3 has a weak and biased strength with respect to the surface extending in the left-right direction of the vehicle body because it is supported at a certain position, when a load is input to the center pillar 3, as shown in FIG. As shown, the continuous portion of the wall portion 8c and the flange 8d may extend and the center pillar 3 may be largely deformed.

Moreover, if the support means 9 is to be provided at the center position of the anchor plate 8 in the vehicle front-rear direction, only a small one can be used. Therefore, the load is input from a position deviated from the center of the center pillar 3, and the above-described center The deformation of the pillar 3 is even greater.

Since the deformation of the center pillar 3 is influenced by the load along the direction of the resultant force f3 of the force f1 in the vehicle front-rear direction and the force f2 in the vehicle body left-right direction, the flange 8d extends in the direction of the resultant force f3. Will end up.

The present invention has been made in view of the above circumstances, and an anchor plate in which a large supporting means can be arranged in the center of the pillar and the strength of the pillar can be improved without increasing the size of the pillar. It is intended to provide.

【Example】

 Next, an embodiment of the anchor plate of the present invention will be described with reference to the drawings.

In FIG. 3, reference numeral 10 denotes a vehicle body having a center pillar 13 which is formed by dividing the front and rear door openings 11 and 12.

As shown in FIGS. 1 (A) and 1 (B), the center pillar 13 is formed in a hollow shape by aligning the inner plate 14 and the outer plate 15 with the front and rear edges of the vehicle body. Is equipped with a reinforcement plate 16 and an anchor plate 17 for mounting a seat belt anchor (not shown).

The reinforcement plate 16 has a cross-sectional hat shape including flanges 16 a and 16 b extending in the vehicle front-rear direction, and forms a closed cross-section with the inner plate 14. The flange 16a is joined by spot welding while being sandwiched between the flanges 14a and 15a of the inner plate 14 and the outer plate 15, and the flange 16b is sandwiched between the flanges 14b and 15b of the inner plate 14 and the outer plate 15. Are joined by spot welding.

The anchor plate 17 is joined to the inner wall surface 14 c of the inner plate 14 by spot welding in close contact with the inner plate 14 and a supporting portion 17 a to which a supporting means (anker nut) 18 for mounting a seat belt anchor is fixed. A flange (first flange) 17b formed by bending an edge portion of the portion 17a located in front of the vehicle body toward the outside of the vehicle body, and an edge portion of the support portion 17a located behind the vehicle body as shown in FIG. A flange (a second flange) 17c bent outward, and a flange (a third flange) 17d formed by bending a part of the flange 17c located in the vicinity of the supporting means 18 in the vehicle front-rear direction; A crank portion 17e formed at a continuous portion of the support portion 17a and the flange 17d, a reinforcement portion 17f formed by bending at the vehicle body upper and lower edges of the support portion 17a, 17f is integrally formed.

The crank portion 17e extends along a direction of a resultant force F3 of a force F1 in the vehicle front-rear direction and a force F2 in the vehicle left-right direction, that is, a load direction input from the seat belt to the center pillar 13. There is.

The flange 17b is joined by spot welding to the inner wall surface of the wall portion 16c of the reinforcement plate 16 extending in the vehicle body left-right direction, and the flange 17c faces the wall portion 16c of the reinforcement plate 16 in the vehicle body left-right direction. The inner wall surface of the extending wall portion 16d is joined by spot welding, and the flange 17d is joined by spot welding to the inner wall surface of the flange 16b.

In the above structure, the center pillar 13 has a double structure in which the inner plate 14 and the outer plate 15 form a closed cross section, and the reinforcement plate 16 and the anchor plate 17 form a closed cross section. As a result, for example, strength against a load input to the center pillar 13 from a seat belt (not shown) via the seat belt anchor at the time of a front collision of the vehicle body is secured.

At this time, the anchor plate 17 has a substantially uniform joint structure of two surfaces, each of which is a surface extending in the vehicle front-rear direction (the inner wall surface 14c and the flange 16b) and a surface extending in the vehicle left-right direction (the wall portions 16c and 16d). Since the support means 18 is positioned substantially in the center of the center pillar 13 in the front-rear direction of the vehicle body, the load to the center pillar 13 can be efficiently dispersed with respect to the input, and the strength can be increased. It can be a high center pillar 13. In addition, the strength of the center pillar 13 is improved because the crank portion 17e extends in a direction parallel to the resultant force F3, that is, in a direction effective for the load in the deformation direction of the center pillar 13. Not only can the load be efficiently distributed to the reinforcement plate 17, the inner plate 14, and the outer plate 15 via the flange 17d.

Further, the anchor plate 17 of the present invention can realize a thin center pillar 13 having a significantly improved strength, although the anchor plate 17 is joined by spot welding as in the conventional case. At this time, the flange 17d of the anchor plate 17 can be integrally joined to the respective flanges 14b, 15b, 16b, and in this case, a thinner center pillar can be obtained.

In the above embodiment, the example in which the anchor plate 17 of the present invention is provided on the center pillar 13 is disclosed, but the vehicle body portion on which the seat belt anchor is arranged, for example, the rear pillar is not particularly limited. is not.
