Abstract

(57) [Summary] [Purpose] Prevents deformation of the bracket when the seat belt retractor is locked. [Structure] A seat belt 31, a seat belt retractor 2 having a seat belt winding shaft 33 that winds up the seat belt 31, and a seat belt retractor 2 is positioned on a straight line with a pulling direction of the seat belt 31 when the retractor is locked. A seatbelt mounting device comprising a bracket for mounting the seatbelt retractor 2 on a vehicle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt device. More specifically, it relates to a seat belt retractor mounting structure.

[0002]

2. Description of the Related Art As a conventional seat belt mounting structure, there are actual open sho 61-131354 "seat belt retracting structure (conventional example 1)" and actual open flat 2-105060 "vehicle seat belt device" (conventional example 2) It has been known. In these conventional examples, a technique of attaching a seat belt retractor to a body panel of a vehicle such as an automobile through a bracket is disclosed.

[0003]

However, in the conventional seat belt mounting structure, the pulling load direction of the belt when the retractor is locked and the bracket mounting bracket position are offset. Therefore, when the retractor is locked, a tensile load and a rotational load act on the bracket, which causes a problem that the bracket or the anchor member is deformed.

[0004]

Means for Solving the Problems

A seat belt, a seat belt retractor having a seat belt retracting shaft for winding the seat belt, and a seat belt retractor mounted on a vehicle so that the seat belt retractor is positioned on a straight line with a seat belt pulling direction when the retractor is locked. A seat belt attachment device, characterized in that it comprises a mounting bracket,

[0006] to provide.

[0007]

The bracket is attached to the vehicle so that the seat belt retractor is mounted on the vehicle so that the seat belt retractor is aligned with the seat belt pulling direction when the retractor is locked. Therefore, deformation of the bracket is prevented when the retractor is locked.

[0008]

Embodiment An explanation will be given according to FIG. 1 showing a perspective view and FIG. 2 showing a plan view of an embodiment of the present invention.

Reference numeral 21 is a quarter inner panel of an automobile body. The attachment surface 23 is provided on an extension of the seat belt 31 in the pulling-out direction.

1 is a caulking pin, 2 is a seat belt retractor, and the caulking pin 1 is a seat belt retractor 2
It can be installed by caulking. 3 is a first bracket, 4 is a ring, 5 is a weld bolt, 6 is a second bracket, 7
Is a third bracket, 8 is a self-lock nut, 9 is a bolt, and 10 is a weld pin. Reference numeral 33 is a seat belt retracting shaft attached to the seat belt retractor 2 and is always biased in the retracting direction. L1 is a rotation shaft of the seat belt winding shaft 33.

The ring 4 is roll-crimped to the first bracket 3 and the flange portion is spot-welded and attached. Then, the weld bolt 5 is welded and attached to the opposite side of the flange of the first bracket. Further, the caulking pin 1 is used to integrate the seat belt retractor 2. Then, the second bracket 6 and the third bracket 7 having symmetrical shapes are attached by welding, and the bolt holes 11 and 12 are attached.
Through the weld bolt 5. Furthermore, each self-locking nut 8 is attached to the weld bolt 5,
Attach the second bracket and the third bracket to the weld bolt 5.

Then, the second bracket and the third bracket are bent at right angles to the bolt mounting surfaces to form a flat surface,
The body mounting surface 12 that is formed at a right angle to the first bracket is overlaid on the mounting surface 23 on the vehicle body side, and is mounted on the vehicle body with the bolt 9. L2 is the pulling direction of the seat belt 31. θ is the seat belt 3
The angle between the pulling direction of No. 1, that is, the pulling load direction of the seat belt 31 when the retractor is locked and the quarter inner panel 21 of the automobile body is shown. That is, the bracket 3 is attached in a direction orthogonal to the seat belt winding shaft 33.

A shock is applied by using the seat belt 31,
With the retractor lock, since the bracket 3 is attached in a direction orthogonal to the seat belt retracting shaft 33, the action point of the tension load of the seat belt and the bracket 2 are not offset regardless of the winding amount. Since the pulling direction of the seat belt 31, the bracket 6, the body mounting surface 12 of the bracket 7, and the vehicle side mounting surface 23 are substantially linear, the deformation of the bracket is prevented.

[0014]

EFFECT OF THE INVENTION The deformation of the bracket when the seat belt retractor is locked is prevented.
