Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in support structures for seatbelt retractors in automobiles.

Conventionally, as shown in FIGS. 1 and 2, in a vehicle body 2 having a side sill 4 and a pillar 6 that define a part of the interior wall, the inside and outside of a space 8 defined by an inner panel 6a and an outer panel 6b of the pillar 6 are defined. A communicating opening 12 is provided in the inner panel 6a, and the case 16 of the retractor 10 for retracting the seat belt 14 is connected from the opening 12 to the space 8.
the inner panel 4 of the side sill 4 with the bolts 18.
If the case 16 is fixed at position a, when a large force is applied to the seat belt 8 due to a collision or the like, the mounting portion 16a will deform as shown by the two-dot chain line in FIG. Therefore, there was a problem in that the restraint of the occupant by the seat belt 14 deteriorated.

Note that 22 is a trim member disposed along the inner surface of the pillar 6.

Similarly, in a case where the case 16 of the retractor 10 is inserted into the space 8 through the opening 12 and the lower end attachment part 16a of the case 16 is fixed to the inner panel 6a of the pillar 6, the seat belt 8 may be damaged due to a collision or the like. When a large force is applied, the mounting portion 16a deforms and the case 16 protrudes into the vehicle interior 20, which also causes the seat belt 14
In some cases, the restraint of the occupants deteriorated.

Furthermore, since there is no means to force the positioning of the upper end of the retractor 10, the operator must use one hand near the lower end mounting portion 16a of the case 16 to tighten the bolt 18 when fixing the retractor 10 in a predetermined position. When holding the
There was a fear that the retractor 10 would wobble and the efficiency of tightening the bolts 18 would deteriorate.

The present invention was devised in view of the above, and involves inserting a seatbelt retractor into the space formed by the inner panel and outer panel that define the interior wall through an opening formed in the inch panel. is fixed to the opening portion of the inner panel, the retractor has a second groove on the upper part of the case of the retractor that protrudes above the upper edge of the opening of the inner panel and engages with the inner surface of the inch panel. A second locking piece is provided which protrudes above the first locking piece and the upper edge of the opening of the inner panel to lock with the outer surface of the inner panel. The gist of this paper is a support structure for a seatbelt retractor in an automobile, which is characterized by being fixed to a seatbelt retractor.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

In the drawings, parts that are substantially the same as those shown in FIGS. 1 and 2 are designated by the same reference numerals as used above, and detailed explanations thereof will be omitted.

In the present embodiment, the case 16 of the retractor 10 has an upper part that protrudes above the upper edge of the opening 12 of the inner panel 6a to engage with the inner surface of the same inch panel and to make the interior of the case 16. The first locking piece 24 that restricts movement in 20 directions and the opening 1 of the inner panel 6a
A second locking piece 26 is integrally formed that protrudes above the upper edge of the case 16 and locks with the outer surface of the inner panel to restrict movement of the case 16 in the eight directions of the space. .

According to the above configuration, even when a large force is applied to the seat belt 14 during a collision, the first locking piece 24 locks with the inner surface of the upper edge of the opening 12 of the inner panel 6a.
The protrusion of the case 16 into the vehicle interior 20 is restricted, and deformation of the mounting portion 16a is prevented, thereby eliminating the above-mentioned conventional problems.

Further, at the upper part of the case 16 of the retractor 10, not only the first locking piece 24 but also a second locking piece 26 that restricts movement of the case 16 into the space 8 is provided. If it is located in the correct position, the compartment 2 of the same case 16
Both the fall in the 0 direction and the fall in the 8 direction of the space are regulated, and the worker can easily hold the case 16 in the normal position with one hand during the work of fixing the retractor 10.

Therefore, the operator can easily hold the case 16 in the correct position with one hand and tighten the bolts 18 with the other hand, thereby making it extremely easy to fix the retractor 10. play.

In addition, in the above embodiment, the mounting portion 16 of the case 16
a is fixed to the inner panel 4a of the side sill 4, but even if the mounting portion 16a is fixed to the inner panel 6a, by providing a similar locking piece 24 on the case 16, it can be fixed to the inner panel 4a of the side sill 4. A similar effect can be obtained.
