Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a shoulder anchor attachment structure for an automobile seat belt.

In a conventional automobile, for example, as shown in Fig. 81, a shoulder anchor 2t- is attached to the vehicle body roof site rail 1, and a through ring 4 through which a seat belt 3 is inserted is connected to the shoulder anchor 2, so that the seat belt 3t- The connecting portion of the tongue 5 and the buckle 6 and the shoulder anchor 2 allow the passenger to be restrained to the seat 7 by hanging diagonally on the chest of the passenger in the vertical direction. In Fig. 1, 8 indicates the beam tractor, and 9 indicates the floor side reed force.

By the way, the above-mentioned shoulder anchor 2 is attached. Roof sight rail 1 consists of inner rail ll and outer rail 1
The outer rail 1 is completely connected to the outer rail 1 to form a closed cross section.
Roof panel 1 to drip channel 13 joined to 2
The roof sight rail 1 extends in the longitudinal direction of the vehicle body on the side of the roof panel 14, and functions as a longitudinal strength member for the upper portion of the vehicle body. Inner rail 1
1 has a stiffener with a weld nut 16 on the inner surface.
15 was polymerized and bonded. This stiffener 15 has side walls 15 bent on both sides & 7279 pieces 1
The flange pieces 15b each extend laterally, and the flange pieces 15b are adapted to abut against an outer rail stiffener 17 joined to the inner surface of the outer rail 12. Stiffener 15 and inner rail 11 weld tension)
There are bolt insertion holes 18 in the parts corresponding to 16, respectively.
, 19 t- are formed, and the shoulder anchor 2 is inserted into these bolt insertion holes 18 and 19 and screwed into the weld nut 16 and fastened.

By the way, the shoulder anchor 2 of the inner rail 11 mentioned above
The inclination angle θ of the mounting surface 11JL of 0 is determined so that the free end of the shoulder anchor 2 does not interfere with the door glass (not shown) and the load from the seat belt 3 does not act on the bolt 20 in the direction of removal. ing. As a means of ensuring the mounting surface 114Lk with a constant inclination angle θ, the bottom wall flb of the inner rail 11' is expanded in the vehicle width direction dimension Ls'r and stretched toward the single compartment side, as shown by the chain line in FIG. It is conceivable that the mounting surface 11at- be formed at the position indicated by the solid line in the same figure by allowing the mounting surface 11at to come out and then partially embossed. When such a means is adopted, there is an advantage that the area of the closed cross section formed by the inner rail 11 and the actuator rail 12 shown by the chain line can be expanded. Not only does it narrow the living space of a single room to create a shape, but the addition of shoulder anchors 2 to the roof trim 21, which is stretched from the back side of the roof panel 14 along the inner rail 11, makes the embossed part Wrinkles occur and seriously impair the interior appearance of the vehicle. For this reason, the inner rail 1 is generally used as shown by the solid line in the same figure.
1 is formed as a whole at the above-mentioned inclination angle θ, the dimension t2 of the bottom wall 11b in the vehicle width direction is made as small as possible, and the roof trim 21 is prevented from being wrinkled at the shoulder anchor 2 attachment part. As a result, there is no degree of freedom in shaping the inner rail 11, and the closed area of the roof sight rail 1 is reduced, resulting in a large sacrifice in strength of the roof sight rail 10.

4. In view of the conventional situation, the present invention provides a seat belt shoulder anchor mounting structure that allows the shoulder anchor to be mounted at a regular mounting angle without sacrificing the strength of the roof sight rail and the appearance of the vehicle interior. The purpose is to

Structure of the Invention In order to achieve the above object, the eighth invention includes a seat belt anchor installed at a predetermined inclination angle, spaced from the inner rail, within the roof site rail where an inner rail and an outer rail form a closed cross section. An anchor plate is provided, and a spacer insertion hole is formed in the shoulder anchor attachment portion of the inner rail, a spacer is inserted into the spacer insertion hole, and the shoulder anchor is connected to the anchor grate with bolts and nuts through the spacer. It is.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals as those of the conventional method described above being attached.

In Fig. 4.5, an anchor plate 22 is provided within the roof site rail 1 consisting of an inner rail IIA and an outer rail 12, and is spaced apart from the inner rail IIA.
The actuator rail 12 is integrally joined at the joint flange portion. A stiffener 1 having a weld nut 16 similar to that shown in FIG.
5 is joined. This anchor plate 22 has the free ends of the shoulder anchor 2 interfering with the door glass (not shown),
The anchor plate 22 and the stiffener 1 are arranged at a preset inclination angle θ so that the load from the seat belt 3 does not act on the bolt 20 in the direction of removal.
Bolt insertion holes 23 and 18 Th are formed in the portions corresponding to 16 (Queldnut No. 5). On the other hand, the inner rail IIA has a free shape that can expand the upper space of the vehicle interior as much as possible without being limited by the inclination angle θ of the anchor plate 22, and can also expand the closed area of the roof site rail 1. In this way, the cross-sectional road is formed into a hat-like shape, with a sloped wall 11A3 having a small inclination angle α spanning the bottom wall 11A, which has a relatively small dimension t3 in the vehicle width direction, and the vertical wall 11A2. Further, an anchor plate 22. is attached to the inclined wall 11A8. Bolt insertion hole 23 of stiffener 15,
A spacer insertion hole 24't is formed concentrically with 18. Then, insert the shoulder anchor 2 into the spacer insertion hole 2.
4, insert the spacer 25 into the spacer 2, and screw the bolt 20 into the spacer 2.
5. The bolts are passed through the bolt insertion holes 23 and 18 and screwed into the weld nut 16 for fastening.

According to the structure of the above embodiment, the shoulder anchor 2 is connected to the anchor plate 22 disposed at a predetermined inclination angle θ via the spacer 25 with the bolts and nuts 20, 16, so that it can be mounted at the normal mounting angle. On the other hand, the inner rail IIA can be formed in a free shape that can expand the vehicle interior space and the enclosed area of the roof site rail 1 without being restricted by the inclination angle θ of the anchor plate 22. The enclosed area of the roof site rail 1 can be expanded, the strength of the roof site rail 10 can be increased as well as the single room space will not be narrowed. Also,
The roof trim 21 is the inclined wall 11A3 of the inner rail IIA.
Since it can be stretched uniformly along the surface, there is no problem of wrinkles, and the appearance of the interior of the vehicle is not spoiled.

Effects of the Invention As described above, according to the present invention, the shoulder anchor can be mounted at a normal mounting angle to avoid interference with the door glass, and no load is applied to the mounting bolt, and the inner rail of the roof sight rail can be mounted at a normal mounting angle. can be shaped freely without being restricted by the installation angle of the shoulder anchor, so it is possible to expand the closed area of the roof site rail and the single room space. This has a great practical effect in that the roof trim can be installed in an orderly manner and the interior appearance of the vehicle can be improved.
