Abstract

PURPOSE:To provide a seat belt device for vehicle, with which a side trim is never removed even in the case where a large tension is generated in a webbing. CONSTITUTION:A lead-in port 18 formed in the lower end of a side trim 17 is formed into a semi-circular shape around of the tip of an anchor 10 and has a radius size R large enough for preventing a contact of a webbing W under the used condition with the side trim 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat belt device.

[0002]

2. Description of the Related Art As a conventional vehicle seat belt device, for example, ones shown in FIGS. 3 and 4 are known (for a similar technique, see Japanese Utility Model Laid-Open No. 56-109758).

Reference numeral 1 denotes a side panel (vehicle body) on the right rear portion of the automobile. Inside the side panel 1, a side trim 2 is provided by a clip means (not shown). A retractor (ELR) 3 that can wind and pull out the webbing W is fixed to a side panel 1 inside the side trim 2.

An opening 4 is formed on the upper surface of the side trim 2.
Further, an escutcheon 6 having an insertion opening 5 for the webbing W is attached to the opening 4.

The webbing W in the retractor 3
Is drawn out of the side trim 2 through the opening 4 and the insertion opening 5, and then passed through the through ring 7 provided at the upper portion of the side panel 1, and then the slit-shaped introduction opening 8 at the lower end of the side trim 2. After that, it is fixed to the tip of an anchor 10 set on the floor panel (vehicle body) 9. The tongue 11 is inserted through the webbing W.

On the other hand, a rear seat 12 is installed at a position adjacent to the side trim 2. An outlet 13 is formed near the center of the seat cushion 12a of the rear seat 12, and a fixed belt 15 having a lower end connected to an anchor 14 below the rear seat 12 is pulled out from the outlet 13. A buckle 16 is attached to the tip of the fixing belt 15. The tongue 11 of the pulled-out webbing W is inserted into and engaged with the buckle 16 so that the occupant on the rear seat 12 can be restrained by three-point support.

[0007]

However, in such a conventional technique, since the inlet 8 formed at the lower end of the side trim 1 has a slit shape, the webbing W is mounted by sudden braking or the like. When the occupant suddenly bends forward and a large tension is applied to the webbing W, the tension may be applied to the lower end of the introduction port 8 and the side trim 2 may come off the side panel 1.

The present invention has been made in view of such a conventional technique, and provides a vehicle seat belt device in which the side trim is not likely to come off even if a large tension is applied to the webbing.

[0009]

In order to achieve the above object, a vehicle seat belt device according to the present invention has a semicircular introduction port formed at the lower end of the side trim with the tip of the anchor as the center. And has a radius size such that the used webbing does not come into contact.

[0010]

According to the vehicle seat belt device of the present invention,
Since the introduction port has a semicircular shape centered on the tip of the anchor and has a radius size such that the webbing in use is not in contact, even if a large amount of tension is generated in the webbing due to sudden braking, etc. Do not add to the bottom of the inlet.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

The inlet 18 formed at the lower end of the side trim 17 of this embodiment has a semicircular shape. The semicircular shape of the introduction port 18 is centered on the tip of the anchor 10 to which the webbing W is connected. The radius size R of the introduction port 18 centered on the tip of the anchor 10 is set so that the webbing W in use cannot come into contact therewith. That is, the webbing W draws an arc locus about the tip of the anchor 10 according to the physique of the occupant and the posture of the occupant. Is set to. In addition, a narrow-width flange 18a directed inward is formed at the edge of the introduction port 18.

According to this embodiment, the introduction port 18 has a semicircular shape with a radius size R, and the webbing W and the edge of the introduction port 18 are not in contact with each other. Suddenly bends forward due to sudden braking, etc., and retractor (ELR) 3 locks and webbing W
Even if a large amount of tension is generated in, the tension does not act on the edge portion of the introduction port 18. Therefore, the side trim 17 does not come off from the side panel 1.

Further, a flange 18a is provided at the edge of the inlet port 18.
As a result, the rigidity of the portion of the inlet 18 is increased, and the generation of low-grade sound when the vehicle is traveling is prevented. Further, since the edge portion of the introduction port 18 is in a non-edge state due to the flange 18a, the webbing W is attached to the side trim 17
Even if the corresponding portion of the webbing W comes into contact with the edge portion of the introduction port 18 in a non-use state (state shown in phantom line in FIG. 2) for storing along with, the contact portion does not rub unnecessarily.
Further, it is safe even when an occupant puts his / her hand in the inlet 18.

In addition, since the introduction port 18 is larger than the conventional one, it is advantageous in terms of workability of attaching the side trim 17. That is, since the webbing W has a structure that penetrates the opening 4 of the side trim 17, the webbing W is passed through the opening 4 of the side trim 17 in advance, and then the retractor 3 on the side of the webbing W and the through Although it is necessary to attach the ring 7 and the anchor 10, as described above, the side inlet 17 is large, so the side trim 17
1 on the floor panel 9 and then the inlet 1
It is possible to insert the anchor 10 by putting a hand inside from the position 8. That is, since it was a slit-shaped introduction port in the past, it was necessary to lift the side trim by some method while the anchor 10 was attached.
There is no such trouble in this embodiment.

[0016]

The seat belt device for a vehicle according to the present invention has the contents as described above, and the introduction port has a semicircular shape centered on the tip of the anchor and the webbing in use is not Even if a large amount of tension is applied to the webbing due to sudden braking, the tension is not applied to the lower end of the inlet because it has a radius size that makes contact.
