Description

[Detailed Description of the Invention] This invention relates to an improvement in the structure for attaching a seat belt to a vehicle body in order to secure occupants safely in their seats in the event of an automobile accident.

The above seat belts depend on how you fasten them.
There are two-point seat belts and three-point seat belts, and the general configuration of a three-point seat belt is as shown in Figure 1.
For example, there is a retractor 2 at the bottom of center pillar 1.
Attach the through link 3 to the upper part of the center pillar 1, insert the middle of the webbing 4 pulled out from the retractor 2 into the through link 3,
An anchor plate 5 at the end of the webbing 4 is rotatably attached to the lower side of the vehicle body, and an anchor plate 9 of a short inner belt 8 having a buckle 7 is rotatably attached to the inner lower part of the seat 6. When not in use, the webbing 4 is automatically wound up in tension between the anchor plate 5 and the through link 3 to prevent it from slackening due to the winding action of the retractor 2, and when in use, the webbing 4 is Holding the inserted tongue plate 10, pull out the webbing 4 from the retractor 2, and attach the tongue plate 10 to the buckle 7 of the inner belt 8.
By engaging the webbing 4, the webbing 4 is attached to the passenger's waist and diagonally below the shoulders.

Conventional three-point seat belt retractor 2 above
The specific structure of attaching the webbing 4 to the vehicle body and the anchor plate 5 at the end of the webbing 4 to the vehicle body are separately attached as shown in FIG. 2 or 3.

To explain FIG. 2, a retractor housing hole 11 is formed in the lower part of the center pillar inner plate 1a, and most of the retractor 2 is attached to the center pillar 1.
the retractor 2.
The mounting bracket 12 is fixed to the inner plate 13a of the side sill 13 with an anchor bolt 14, and the anchor plate 5 at the end of the webbing 4 is attached to the inner plate 13a of the side sill 13 at a different mounting position from the retractor 2. It was attached rotatably with bolt 15.

A center pillar garnish 16 for covering the mounting portion of the retractor 2 is attached to the center pillar inner plate 1a, and a floor mat 18 is laid on the floor panel 17 to improve the aesthetics of the room. It is being done.

In particular, in a floor mat installation method called the wall-to-wall method, both sides of the floor mat 18 are extended to the upper part of the side sill inner plate 13a, and the floor mat 18 is clamped and fixed to the scuff plate 19 attached to the side sill 13. ing.

In the wall-to-wall system, the anchor plate 5 is attached to a part of the floor mat 18.
It is necessary to provide a slit 20 through which the webbing 4 is taken out. Therefore, in the configuration shown in FIG. 2, it is very troublesome to attach the retractor 2 and the anchor plate 5 at the end of the webbing 4.

That is, first, the retractor 2 is attached to the vehicle body, then the floor mat 18 is laid down, and then the anchor plate 5 at the end of the webbing 4 is attached to the vehicle body through the slit 20 with the anchor bolt 15. In this case, the floor mat 18 is It gets in the way and has very poor workability. After the installation of the anchor plate 5 is completed, the center pillar garnish 16 is installed, and this garnish 16
A scuff plate 19 is attached to the side sill 13 so as to cover the lower part of the floor mat 18 and the edge of the floor mat 18.

With the above configuration, there is the above-mentioned difficulty in attaching the anchor plate 5, and when the seat belt is used, especially when the webbing 4 is pulled out, the floor mat 18 may be pulled up by the slit 20 and rolled up. Another drawback was that the floor mat 18 could shift.

The one in FIG. 3 has been adopted to avoid the above-mentioned drawbacks, and the floor mat 18 is provided with a large notch 18a at a location corresponding to the attachment portion of the retractor and anchor plate 5 to the vehicle body. This part is separately covered using a resin garnish 21, and this garnish 21 is formed with a pull-out opening 21a for the webbing 4.

However, in the case shown in FIG. 3 above, which is similar to that shown in FIG. , the workability is poor, and the anchor plate 5
Since it is necessary to provide a drawer part for pulling out the webbing 4 from the webbing, a means for improving the appearance of these webbing drawer parts is required, which inevitably increases the number of parts and is not favorable in terms of assembly workability. .

Therefore, this invention provides a position regulating and temporary fixing means for the retractor, and attaches the retractor and the anchor plate at the end of the webbing to the lower side of the vehicle body.
The retractor is fixed with one common stepped anchor bolt with the floor mat in between, and the anchor plates are tightened together so that they can rotate, thereby solving the above-mentioned conventional drawbacks at once.
A specific example of this invention will be explained below with reference to FIG.

In FIG. 4, 30 is webbing,
One end thereof is wound around a retractor 31, an anchor plate 32 is attached to the other end, and the middle part is inserted through a through link 33 attached to the upper part of the inside of the passenger compartment. It is slidably inserted into the.

A mounting bracket 35 is attached to the lower part of the retractor 31, and protrusions 36 and 37 are formed on a part of the mounting bracket 35 and the upper part of the retractor 31 as position regulating and temporary fixing means.

A retractor accommodating hole 39 is formed in the lower side of the vehicle body where the retractor 31 is attached, that is, in the lower part of the inner plate 38a of the center pillar 38, and
Engagement holes 40 and 41 are formed above and below in correspondence with the projections 36 and 37, respectively.

There are mounting holes 42 in the mounting bracket 35 of the retractor 31.
Correspondingly, a mounting hole 44 is also formed in the inner plate 43a of the side sill 43, and a nut 45 is fixed to the back side of the mounting hole 44.

Correspondingly, the floor mat 46 is also formed with an insertion hole 47, and these are attached by inserting a stepped anchor bolt 49 into the insertion hole 48 formed in the anchor plate 32 at the end of the webbing 30. Ru.

That is, first, the retractor 31 is accommodated and mounted in the retractor accommodation hole 39 of the center pillar inner plate 38a by aligning the upper and lower projections 36, 37 with the engagement holes 40, 41. In this case, the upper projection 36 is hook-shaped, and therefore both projections 36, 37
Although the engagement of the retractor 31 with the engagement holes 40 and 41 alone can serve as a means for regulating the position and temporarily fixing the retractor 31, the fourth
In the illustrated embodiment, in order to further secure the temporary fixation of the retractor 31, a tatu pin screw 50 is used, and 51 and 52 are tatu pin screw insertion holes provided in a part of the projection 36 and a part of the center pillar inner plate 38a. be.

After temporarily fixing the retractor 31 as described above, the floor mat 46 is laid on the floor panel 53, and the anchor plate 32 is placed on it with the washer 5.
4. Overlap via spring washer 55,
As shown in the cross-sectional view of the figure, when a stepped anchor bolt 49 is fitted and screwed onto the nut 45, a washer 54 is inserted between the end surface of the large diameter stepped portion of the stepped anchor bolt 49 and the nut 45. , the mounting bracket 3 of the retractor 31 via the spring washer 55.
5 is tightened and fixed, and the anchor plate 32
The large diameter portion of the stepped anchor bolt 49 is loosely fitted and rotatably tightened together.

In this case, since the retractor 31 is temporarily fixed under the positional restrictions of the protrusions 36, 37, etc., it will not move or fall off when the floor mat 46 is installed, and therefore the retractor 31 and the anchor plate 32 can be tightened together. is extremely easy. Moreover, there is no need to provide the floor mat 46 with a draw-out opening for the webbing 30 or the like.

After this, although not shown in the drawings, the center pillar garnish and scuff plate may be attached in the same manner as before.

As explained above, this invention consists of a retractor attached to the lower side of the vehicle body, a through link attached to the upper inner side of the vehicle, one end of which is wound around the retractor, and the other end of which is wound through the through link. In a seat belt system that has a webbing that is secured to the vehicle body, the seat belt system is equipped with a retractor and a retractor, which is provided with projections on the upper and lower parts for position regulation and temporary fixing that fit into engagement holes provided at the lower side of the vehicle body. The retractor was tightened and fixed with a common stepped anchor bolt by sandwiching the floor mat between the anchor plate attached to the end of the webbing that had been pulled out, and the anchor plate was rotatably tightened together. The plate can be rotated smoothly following the movement of the waving without being compressed by the floor mat and rattling, making it easy to install the retractor, and allowing the retractor and anchor plate to be installed by tightening at one point. Since the webbing is stopped outside the floor mat, there is no need for a webbing opening in the floor mat, and the number of parts can be reduced and assembly work efficiency can be improved.

It is clear that the present invention can be applied not only to a three-point seat belt system but also to a two-point seat belt system.
