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 seat belt device for a vehicle, for example, the one shown in FIGS. 3 and 4 is known (see Japanese Utility Model Laid-Open No. 56-109758 as a similar technology).

[0003] Reference numeral 1 denotes a right side rear panel (vehicle body) of an automobile. A side trim 2 is provided inside the side panel 1 by clip means (not shown). A retractor (ELR) 3 that can take up 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 a webbing W insertion hole 5 formed therein is attached to the opening 4.

Then, the webbing W in the retractor 3
Is drawn out of the side trim 2 through the opening 4 and the insertion opening 5, then through a through ring 7 provided at the upper part of the side panel 1, and then into a slit-like inlet 8 at the lower end of the side trim 2. And is fixed to the tip of an anchor 10 set on a floor panel (vehicle body) 9. Note that a tongue 11 is passed through the webbing W in the middle.

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 12 a 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 drawn out from the outlet 13. A buckle 16 is attached to the tip of the fixed belt 15. The tongue 11 of the webbing W pulled out 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 is slit-shaped, 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 is applied to the lower end of the inlet 8 and the side trim 2 may come off the side panel 1.

The present invention has been made by paying attention to such a conventional technique, and an object thereof is to provide a vehicle seat belt device which does not have a risk of side trim coming off even if a large tension is applied to the webbing.

[0009]

According to the present invention, in order to achieve the above object, an inlet formed at a lower end of a side trim has a semicircular shape centered on a tip of an anchor. And according to the occupant's physique and posture
Circle the webbing of use state is centered on the tip of the anchor Te
It has a radius size that is non-contact even if an arc trajectory is drawn .

[0010]

According to the vehicle seat belt device of the present invention,
The inlet has a semicircular shape centered on the tip of the anchor, and
The physical structure of the occupant, Ann webbing of use state according to the posture
Even if a circular locus centered on the tip of the mosquito is drawn, it has a radius size that does not make contact, so even if a large tension is applied to the webbing due to sudden braking or the like, the tension is not applied to the lower end of the inlet.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. In addition, the same reference numerals are given to portions common to the related art, and overlapping 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 inlet 18 is centered on the tip of the anchor 10 to which the webbing W is connected. The radius R of the inlet 18 centered on the tip of the anchor 10 is such that the webbing W in use cannot come into contact. That is, the webbing W draws an arc trajectory centered on the tip of the anchor 10 according to the occupant's physique and the occupant's posture, but the radius size R such that the webbing W does not touch even if the webbing W draws such an arc trajectory. Is set to A narrow flange 18a is formed at the edge of the inlet 18 so as to face inward.

According to this embodiment, since the inlet 18 has a semicircular shape with a radius R and the edge of the inlet 18 does not contact the webbing W, for example, an occupant wearing the webbing W Suddenly bends forward due to sudden braking, etc., the retractor (ELR) 3 locks and the webbing W
Does not act on the edge of the inlet 18 even if a large tension is generated. Therefore, the side trim 17 does not come off the side panel 1.

Further, a flange 18a is provided at an edge of the inlet 18.
Is formed, the rigidity of the inlet 18 is increased, and the generation of low-pitched sound during running of the vehicle is prevented. Further, since the edge of the introduction port 18 is in a non-edge state by the flange 18a, the webbing W is
When the corresponding portion of the webbing W comes into contact with the edge of the introduction port 18, the contact portion does not rub undesirably.
It is also safe when the occupant places his hand in the inlet 18.

In addition, since the inlet 18 is larger than in the prior art, it is advantageous in terms of workability in mounting the side trim 17. That is, since the webbing W has a structure penetrating 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 webbing W side and the through It is necessary to mount the ring 7 and the anchor 10, but as described above, since the inlet 18 is large, the side trim 17
Is placed on the floor panel 9 and then the inlet 1
The work of attaching the anchor 10 can be performed by putting a hand into the inside from the position 8. That is, conventionally, since the slit-shaped inlet was used, it was necessary to lift the side trim by some method during the installation work of the anchor 10.
In this embodiment, there is no such trouble.

[0016]

The seatbelt 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 used. Since the webbing has a radius size to be in contact, even if a large tension is applied to the webbing due to sudden braking or the like, the tension is not applied to the lower end of the inlet.
