Description

Mounting structure of seat belt webbing guide for automobile}

The present invention relates to a seat belt webbing guide mounting structure for an automobile, and more particularly, in a mounting structure for mounting a webbing guide for hanging and supporting a seat belt webbing in a center pillar interior side, wherein the webbing guide is in the front-rear direction of the vehicle body. In addition, it is possible to rotate about the longitudinal axis of the mounting bracket installed in parallel with the center pillar to be rotated in the optimum direction according to the take-out / retracting direction of the webbing, thereby preventing twisting of the seat belt and easy withdrawal The present invention relates to a seat belt webbing guide for an automobile which can be pulled in and can lower the strength of the retractor spring to improve the feeling of pressure and the feeling of pressure caused by the resistance of the webbing guide.

Generally, seat belts installed in a vehicle are installed to prevent passengers from jumping out of the vehicle body in order to prevent secondary collisions or to alleviate the impact during a vehicle collision. A three-point seat belt is used in which a shoulder belt for shoulder restraint is combined.

3 is a front view illustrating a conventional seat belt webbing guide for automobiles.

As shown in the drawing, the webbing 10 drawn out when the passenger restrains the seat belt is drawn out of the retractor 20 fixed to the lower side of the vehicle body and supported by the webbing guide 40 installed above the indoor center pillar 30. It is becoming.

As the webbing guide 40, a D-ring having a ring-shaped shape having a 'D' shape is mounted to a bolt 44 so as to be rotatable in the front-rear direction of the vehicle body at an upper neck portion 40a, and a webbing through hole formed at a lower side thereof. At 42, webbing 10 is supported by hanging.

However, in the conventional webbing guide mounting structure, since the webbing guide 40 is mounted to be rotatable only in the front and rear direction of the vehicle body, twisting occurs when drawing out and drawing in. In particular, when the webbing 10 is pulled out, the webbing 10 has a webbing passing hole ( There was a problem that requires a large force to be driven to one side of 42).

In addition, the webbing 10 is wound only by the force of the retractor 20 at the time of inlet, but is not easily wound due to the twisting and the retracted direction of the webbing 10, and when the strength of the retractor spring is raised to solve this problem. There was a problem that the pressure increases when worn.

The present invention has been made in view of the above-described problems, and in the mounting structure for mounting the webbing guide which hangs and supports the seat belt webbing to the center pillar interior side, the webbing guide is not only the front and rear direction of the vehicle body, but also the center pillar. It can be rotated about the longitudinal axis of the mounting bracket installed in parallel with it so that it can be rotated in the optimum direction according to the drawing / drawing direction of the webbing, thereby preventing the twisting of the seat belt and making it easy to take out / retracting. In addition, the purpose of the present invention is to provide a seat belt webbing guide for an automobile that can lower the strength of the retractor spring, thereby improving the feeling of pressure and the feeling of pressure caused by the resistance of the webbing guide.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

In the seat belt webbing guide mounting structure for automobiles according to the present invention, the mounting bracket 50 for mounting the webbing guide 40 is installed at the upper side of the indoor center pillar 30 by the main bolt 54 and the long washer 56. Fastening so as to be rotated in the front-rear direction of the vehicle body at a predetermined interval;

The lower portion of the mounting bracket 50 is inserted into the webbing guide to form a bolt-shaped portion 52 formed at the lower end of the mounting bracket 50 at the inside of the webbing guide 40. To be fastened to (59), characterized in that the webbing guide 40 can be rotated about the longitudinal axis of the mounting bracket (50).

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a cross-sectional view illustrating main parts of a seat belt webbing guide mounting structure for automobiles according to the present invention, and FIG. 2 is a cross-sectional view taken along line 'A-A' of FIG.

As shown in the drawing, in the webbing guide mounting structure according to the present invention, when the webbing guide 40 is mounted, the webbing guide 40 may center the webbing guide 40 as well as the front and rear directions of the vehicle body. ) Is a mounting structure that can be rotated about the longitudinal axis of the mounting bracket 50 is mounted in parallel with.

The mounting bracket 50 which fastens the upper end of the webbing guide 40 is fastened to the upper side of the center pillar 30 by the main bolt 54 and the long washer 56 so as to be rotated in the front and rear direction of the vehicle body. It is becoming.

The webbing guide 40 is mounted at a predetermined interval away from the indoor side of the center pillar 30, and a webbing guide fastened thereto around the longitudinal axis of the mounting bracket 50 arranged in parallel with the center pillar 30. This is to allow the 40 to be rotated.

The main bolt 54 has a length longer than that for the above gap, and the long washer 56 mounted thereon supports the mounting bracket 50 while maintaining the predetermined distance from the center pillar 30. .

1 and 2, the lower side of the mounting bracket 50 is inserted into the inside through the upper end of the webbing guide 40, the lower end of the mounting bracket 50 is formed with a bolt-shaped portion 52 It is fastened to the nut 58 in the inner side of the webbing guide 40, whereby the webbing guide 40 is fastened to the mounting bracket (50).

A washer 59 is inserted between the nut 58 and the webbing guide 40, and a jaw is formed above the bolt portion 52 so that the webbing guide 40 is not compressed when the nut 58 is fastened. Let's do it.

The webbing guide even after the mounting bracket 50 is slightly lengthened by the upper portion of the bolt-shaped portion 52 inserted into the webbing guide 40 by the nut 58 in the bolt-shaped portion 52. 40 can be rotated smoothly.

In this way, the mounting bracket 50 can be rotated in the front and rear direction of the vehicle body about the main bolt 54 fastening it in parallel with the center pillar 30, and the mounting bracket 50 The webbing guide 40 fastened to the lower side may be rotated about the longitudinal axis of the mounting bracket 50.

As a result, in the mounting structure of the webbing guide 40 according to the present invention, the webbing guide 40 may be rotated about the longitudinal axis of the mounting bracket 50 as well as the front and rear direction of the vehicle body. By being able to rotate in an optimal direction according to the drawing / drawing direction, it is possible to solve the problems caused in the conventional webbing guide mounting structure.

As described above, according to the vehicle seat belt webbing guide mounting structure according to the present invention, in the mounting structure for mounting the webbing guide for hanging the seat belt webbing on the center pillar interior side, the webbing guide is a In addition to the front and rear direction, the seat belt can be rotated about the longitudinal axis of the mounting bracket installed in parallel with the center pillar, so that it can be rotated in the optimal direction according to the drawing / retracting direction of the webbing, thereby preventing the twisting of the seat belt. Withdrawal / retraction can be performed, and the strength of the retractor spring can be lowered, thereby improving the feeling of pressure and the feeling of pressure caused by the resistance of the webbing guide.
