The seat belt anchor 13 can be slid up and down together with the slide plate 9 and the slide unit 12 by pressing a release button 17 after removing a part of the cover 15. The height position can be adjusted to an optimum height position according to the height (seat height) of the occupant.

<Problems to be solved by the invention> However, in such a conventional seat belt vertical position adjusting device, the vertical sliding amount of the seat belt anchor 13 is further increased in order to widen the height position adjusting range of the seat belt S. Even if you try to expand, seat belt anchor 13
Are interlocked with the slide plate 9, and as a result, the vertical sliding amount of the seat belt anchor 13 is regulated by the upper protrusion 10 and the lower recess 7 with which the slide plate 9 contacts.

Further, if the positions of the upper protrusion 10 and the lower recess 7 are to be moved further upward or downward, the garnish 5
It is practically difficult due to its own layout restrictions.

The present invention has been made by paying attention to such a conventional technique, and it is an object of the present invention to provide a seat belt vertical position adjusting device capable of increasing the vertical sliding amount of a seat belt anchor which is an upper support point of the seat belt. Is what you do.

<Means for Solving the Problems> In order to achieve the above object, a seat belt vertical position adjusting device according to the present invention comprises: In addition to the structure in which the slide amount adjustment part is sandwiched between the parts, the slide amount adjustment part is adjusted from the end part and the center part by both end faces of the slide amount adjustment part and the corresponding end faces of the end part and the center part. When a vertical compressive load is applied to the part, an inclined rubbing part that pushes the slide amount adjustment part toward the back side of the garnish is formed, and the end part and the center part are respectively moved by the slide amount adjustment part. And an elastically deformable member connected to the sliding member is provided so as to apply an elastic restoring force to the front side to the slide amount adjusting portion pushed to the rear side by the elastically deformable member.

<Operation> When the upper or lower end of the slide plate is strongly pressed by the stopper portion and a vertical compression load is applied to the slide amount adjustment portion from the end portion and the center portion, the slide amount is increased by the inclined rubbing portion. The adjustment part is pushed out to the back of the garnish.

Therefore, the seat belt anchor is further moved upward or downward by the amount of the slide amount adjustment unit, and the vertical slide amount of the seat belt anchor is increased.

Further, since the slide amount adjusting portion is connected to the end side portion and the center side portion by an elastic deformation member, when the slide plate is returned to the original position, the slide amount adjustment portion becomes the elastic deformation member. Is pushed back to the original position in the slide plate by the elastic restoring force of the slide plate, and is integrated with the slide plate.

<Embodiment> 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 slide plate 20 according to this embodiment is provided with a slide amount adjuster 21 on the upper side and the lower side, respectively.
The slide amount adjustment unit 21 is provided at an intermediate portion on the upper side and the lower side of the slide plate 20. The garnish 5 is disposed between the end portions 20a and 20c of the slide plate 20 and the center portion 20b. It is in a continuous state via a tapered rubbing portion 22 opened toward the back side B. That is, the rubbing portion 22 is located at the end side portion.
When a vertical compressive load is applied to the slide amount adjusting unit 21 from the center side portion 20b, the slide amount adjusting unit
21 is pushed out to the back side B of the garnish 5 so as to be inclined.

The rubbing portions 22 of the end portions 20a, 20c and the central portion 20b are each formed with a projection 23 facing the back side B, and the rubbing portion 22 of one of the slide amount adjusting portions 21 has the projection 23. A hook portion 24 which can be engaged with 23 is formed.
The projection 23 and the hook portion 24 are normally engaged with each other, and the slide amount adjusting portion 21 and the end portions 20a and 20c or the slide amount adjusting portion 21 and the central portion 20b are separated in the longitudinal direction. Not to be. And this slide amount adjustment unit
On the back side B of the end 21, the end portions 20a and 20c and the center portion 20
A leaf spring (elastically deformable member) 25 bridged between b and b is connected.

Next, the operation of the seat belt vertical position adjusting device according to this embodiment will be described. In addition, the upper and lower slide amount adjustment units
Since 21 has the same structure, the upper slide amount adjustment unit 21 will be described as a representative for convenience of explanation. First, the seat belt anchor 13 is slid upward together with the slide plate 20, and the upper end of the slide plate 20 is brought into contact with the upper protrusion 10. The height position of the seat belt 13 at this time is the conventional maximum height h. After the slide plate 20 is further lifted upward after the contact, and a compressive load is applied to the slide amount adjustment unit 21 from the end side portion 20a and the center side portion 20b, the rubbing unit 22 causes Due to the bending deformation of the spring 25, the slide amount adjusting portion 21 is pushed out to the back side B of the garnish 5, and the center side portion 20 b of the slide plate 20.
And the end portions 20a and 20c are in direct contact with each other.
Therefore, the central portion 20b to which the seat belt anchor 13 is attached moves upward by an amount corresponding to the slide amount adjusting portion 21 having slipped to the back side B, so that the uppermost position H of the seat belt anchor 13 is further increased.

In this embodiment, the portion of the slide plate 20 from which the slide amount adjusting portion 21 has come off is hidden by the garnish upper 3, but even if that portion is exposed from the vertically long opening 8 of the garnish upper 3, Since the side portion 20b and the end side portions 20a and 20c are continuous without any step or the like in contact with each other, there is no possibility of causing a problem in appearance.

When the slide plate 20 is lowered, the slide amount adjustment unit 21 is connected to the leaf spring 25 bridged between the center part 20b and the end parts 20a and 20c. Central part due to elastic restoring force of leaf spring 25
It automatically returns to between the end portion 20b and the end portions 20a and 20c, and the slide amount adjusting portion 21 is integrated with the slide plate 20.

Since this slide plate 20 is provided with a similar slide amount adjuster 21 on the lower side, the slide plate
When the slider 20 is slid downward, the lowermost position of the seatbelt anchor 13 becomes lower than before by the same mechanism as in the previous case. Therefore, as a result, the vertical sliding amount of the seat belt anchor 13 is increased.

<Effect of the Invention> The seat belt vertical position adjusting device according to the present invention has the contents described above, and the slide amount adjusting portion is pushed out to the back side of the garnish by strongly pressing the slide plate against the stopper portion. As a result, the seat belt anchor moves further upward or downward by an amount corresponding to the slide amount adjusting unit being removed, and the vertical sliding amount of the seat belt anchor is increased. Therefore, the adjustment range of the optimum height position of the seat belt is expanded, so that the occupant can be more reliably restrained by the seat belt.

Conversely, even if the length of the slide plate is small, it is possible to secure a sufficient amount of vertical sliding of the seat belt anchor, so shortening the slide plate will increase the layout flexibility in garnishes and roof trims. Is also possible.
