Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoulder anchor support mechanism for slidably supporting a shoulder anchor by a center pillar in a vehicle such as a passenger car.

[0002]

2. Description of the Related Art As shown in FIG. 4, a shoulder anchor of a seat belt is slidably supported vertically (UP direction) along a center pillar 1 of a passenger car or the like, for example, on the indoor side (IN) of the center pillar 1. A shoulder anchor support mechanism is provided. According to the shoulder anchor support mechanism, the shoulder anchor can be adjusted at an arbitrary position so that the occupant sitting on the seat can fasten the seat belt in an optimal state.

FIG. 5 shows an example of a conventional shoulder anchor support mechanism or a configuration around a garnish in which this mechanism is installed. The shoulder anchor support mechanism includes a slider 3 that slides along a guide groove 2 a of a slide joint 2 fixed to the center pillar 1, a garnish 4 attached to the indoor side of the center pillar 1, and an opening 4 a of the garnish 4. A shoulder anchor 5 coupled to the exposed slider 3; a slide plate 6 which engages with the slider 3 and is slidable along an opening 4a of the garnish 4; and an energy absorbing member fixed to the center pillar 1 inside the garnish 4. (Hereinafter, referred to as EA ribs). The EA rib is used to buffer the impact of a collision between the occupant and the vehicle when the vehicle receives any impact. In the case of the EA rib 7 set on the center pillar, the EA rib is particularly designed to protect the occupant's head. For the purpose, inside the upper garnish of the center pillar,
The slide plate 6 can be attached to a position where it does not interfere with the slide.

[0006] As shown in FIGS. 6 and 7, the slide plate 6 has an opening 4 a at the inner surface of the garnish 4.
Are slidably supported by a plurality of guide pieces 4b formed so as to protrude from the peripheral edge of. The slide plate 6 slides up and down a predetermined stroke above and below the opening 4a of the garnish 4 (FIG. 6B, the shaded area), whereby the position of the shoulder anchor 5 can be adjusted.

[0005]

By the way, in the conventional shoulder anchor support mechanism, in the sliding area of the slide plate 6 as shown in FIG. In this case, reinforcement such as the EA rib cannot be provided, and a gap must be provided between the slide plate 6 and the garnish 4 in order to make the slide plate 6 easily slide. However, this gap may cause rattling of the slide plate 6 as it is. Further, as described above, in the sliding area of the slide plate 6, it is substantially impossible to provide reinforcement such as an EA rib, so that when an impact is applied due to, for example, a collision with a vehicle, energy is absorbed by the impact. Could not.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a shoulder anchor support mechanism which can perform a smooth operation, has an increased rigidity, and is excellent in energy absorption performance.

[0007]

A shoulder anchor supporting mechanism according to the present invention is a mechanism for slidably supporting a shoulder anchor in a center pillar, and slides along a guide groove of a slide joint fixed to the center pillar. A slider, a shoulder anchor coupled to the slider exposed from the garnish opening attached to the center pillar, a slide plate that engages with the slider and can slide along the garnish opening, and is fixed to the inside of the garnish via the slide plate. EA ribs. In the shoulder anchor support mechanism of the present invention, a slope-shaped rib is preferably formed on the inner surface of the garnish along the sliding direction of the slide plate from the garnish opening, and is positioned by engaging the EA rib with a proper position of the slope-shaped rib. It is configured to be. Further, the shoulder anchor support mechanism of the present invention is preferably guided by the EA rib so that the slide plate slides while elastically deforming near the garnish opening.

According to the present invention, the garnish and the EA rib are sub-assembled by using the slide plate, and the sub-assembly is then attached to the body. In particular, the slide of the slide plate from the garnish opening on the inner surface of the garnish Slope-shaped ribs were formed extending along the direction. By newly providing a rib near the garnish opening in this manner, garnish rigidity and energy absorption performance can be effectively increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a shoulder anchor support mechanism according to the present invention will be described below with reference to FIGS. I do.

FIG. 1 shows a configuration example of a shoulder anchor support mechanism according to an embodiment of the present invention or a garnish around which the mechanism is installed. The shoulder anchor support mechanism includes a slider 3 sliding along a guide groove 2 a of a slide joint 2 fixed to the center pillar 1, a garnish 4 attached to the indoor side of the center pillar 1, and an opening 4 a of the garnish 4. A shoulder anchor 5 coupled to the exposed slider 3; a slide plate 6 that engages with the slider 3 and is slidable along an opening 4a of the garnish 4; and an EA fixed inside the garnish 4 via the slide plate 6.
Ribs (ribs for energy absorption) 7.

A webbing (seat belt) 8 is inserted into the hole 5a of the shoulder anchor 5. In this manner, by sliding the slider 3 along the guide groove 2a, the position of the shoulder anchor 5 can be adjusted up and down, so that the seat belt wearing property or wearing feeling can be appropriately adjusted.

As shown in FIG. 2, slope-shaped ribs 9a and 9b are formed on the inner surface of the garnish 4 so as to extend from the opening 4a thereof along the sliding direction of the slide plate 6. These sloped ribs 9a, 9b
Are provided above and below the opening 4a as shown in FIG. In this example, the EA rib 7 is, as shown in FIG.
It has four lateral ribs 7a, 7b, 7c, 7d. Slope-shaped ribs 9a and 9b have these horizontal ribs 7a to 7a.
Concave portions 10a and 10b (only the rib 9a side is shown in FIG. 3) with which d is engaged are formed. As shown in FIG. 3, the horizontal ribs 7a to 7d of the EA rib 7 are
The EA rib 7 is positioned by engaging with the recesses 10a, 10b of the a, 9b.

The shoulder anchor support mechanism of the present invention is configured as described above. First, when assembling the members, the garnish 4 and the EA rib 7 are sub-assembled using the slide plate 6. Thereafter, the subassembly is mounted on a body (center pillar). As a result, parts such as grips conventionally used for fixing the EA rib 7 to the body can be eliminated, and the EA rib 7 can be eliminated.
The rib 7 can be securely fixed.

According to the shoulder anchor support mechanism of the present invention, the slope-shaped ribs 9a and 9b are provided on the inner surface of the garnish 4 above and below the opening 4a. 9
By newly providing b, the rigidity of the garnish 4 can be effectively increased. Also, the horizontal ribs 7a to 7a of the EA rib 7
The EA rib 7 can be accurately positioned by engaging d with the concave portions 10a and 10b of the slope-shaped ribs 9a and 9b.

The slide plate 6 is slidably supported on the inner surface of the garnish 4 by a guide piece 4b. In this case, as shown in FIG. 2 or FIG.
Above and below, the slide plate 6 rises up to the horizontal ribs 7a to 7d of the EA rib 7, and is appropriately curved. In this manner, when the slide plate 6 slides, the EA rib 7 is pressed against the garnish 4 by sliding while being elastically deformed, and at the same time, the slide plate 6 itself receives the reaction force.

As described above, the slide plate 6 has its own fixing function while exhibiting the function of fixing the EA rib 7. Thereby, when the slide plate 6 slides,
A smooth and proper operation can be realized without rattling.

[0017]

As described above, according to the present invention, by providing a new rib near the garnish opening in this type of shoulder anchor support mechanism, the rigidity of the garnish and the energy absorption performance at the time of a side collision can be effectively improved. Can be enhanced. Further, since the garnish, the EA rib, and the slide plate can be sub-assembled without using a clip, the number of parts can be effectively reduced. Further, there is an advantage that a smooth operation can be performed without rattling between the garnish and the slide plate, and the rigidity of the garnish can be effectively increased.
