Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the mounting structure of a seat adjuster for adjusting the longitudinal position of a seat.

In the case of so-called walk-in seats in which the front and rear positions of the seat can be adjusted, fasteners such as bolts for fixing the lower rail that constitutes the seat adjuster to the mounting bracket and fasteners for fixing the mounting bracket to the floor are used. There was a problem that the aesthetic appearance was spoiled because the fasteners were exposed.

Therefore, it has been proposed to cover the above-mentioned fasteners with a cover, but since the conventional methods cover only the part where the mounting bracket is attached to the floor, it has not been possible to completely eliminate the above-mentioned problems.

The present invention was developed in view of the above circumstances, and its purpose is to provide a seat adjuster mounting part that can cover the mounting part on the rail side with a cover, contributing to further improving the aesthetic appearance. It is there to provide structure. In order to achieve such an object, the configuration of the present invention has a substantially U-shaped cross section, and at least the rear end portion is U-shaped.
A lower rail is fixed to the floor via a mounting bracket fixed to the bottom of the U-shaped groove, and a lower rail is fixed to the underside of the seat and is slidably attached to the lower rail so as to cover the upper opening of the U-shaped groove. The mounting structure of the seat adjuster is composed of an upper rail having a substantially C-shaped cross section; The present invention is characterized in that a cover consisting of a bent upright piece that covers the attachment portion of the attachment bracket to the lower rail is detachably provided.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. Figure 1 is a perspective view of the seat, Figure 2 is a plan view of the cover, Figure 3 is a side view of the cover,
FIG. 4 is a plan view of the seat adjuster mounting portion with the cover attached, and FIG. 5 is a side view of the seat adjuster mounting portion.

The seat 1 shown in FIG. 1 is a so-called walk-in seat equipped with a seat adjuster 2 for adjusting the front and back position of the seat, and each adjuster 2 is installed on the floor (not shown) below the seat 1. Two lower rails 3 arranged in parallel in the front and rear direction,
The lower rail 3 is fixedly installed on the lower surface of the seat 1.
It is composed of an upper rail 4 that is slidable against the upper rail 4. Although not shown, the front end of the lower rail 3 is directly fixed to the floor with bolts, and the rear end is fixed to the floor via a mounting bracket 5 as shown.

The mounting bracket 5 is fixed to the floor using bolts 6, and the lower rail 3 is fixed to the mounting bracket 5 using two bolts 7 and each bolt 7, as shown in FIGS. 4 and 5. It is made up of a nut 8 that screws together. In addition, in Figures 4 and 5,
Reference numeral 9 designates a bracket for preventing rotation of the bolt 7, and both ends 9a and 9b thereof are bent and stand up as shown in the figure, and one upright part 9a is provided with a notch 9c. The mounting portion of the lower rail 3 to the mounting bracket 5 and the mounting portion of the mounting bracket 5 to the floor are covered with a cover 1 as shown in FIGS. 2 and 3.
0 as shown in FIGS. 4 and 5. That is, the cover 10 is integrally molded from an elastic material such as resin. More specifically, as shown in FIG. 2, the cover 10 has a planar shape substantially identical to that of the mounting bracket 5, and has a main body portion 1a and a bent upright piece 1b. Of these, the main body portion 1a is designed to cover the attachment portion of the mounting bracket 5 to the floor. Further, the bent upright piece 10b extends from the main body 10a to the lower rail 3.
The mounting bracket 5 is extended into the U-shaped groove to cover the mounting portion of the mounting bracket 5 to the lower rail 3.
That is, the width b of the bent upright piece 10b is approximately the same as the U-shaped groove width B of the lower rail 3 shown in FIG.
>b), and a hook 10c is formed at the end thereof as shown in the figure. As shown in FIGS. 4 and 5, the cover 10 is constructed by first fitting the main body 0a into the mounting bracket 5 and the outer wall of the lower rail 3, and then inserting the bent upright piece 10b into the U-shaped groove of the lower rail 3. Finally, as shown in FIG.
It can be attached by fitting it into the

The cover 10 can be easily removed by disengaging the hook portion 10c from the cutout portion 9c.

In the above, the mounting part of the lower rail 3 to the mounting bracket 5 and the mounting part of the mounting bracket 5 to the floor are covered with the cover 10, and the bolts 6, 7, etc., which are fasteners, are not exposed to the outside, so that the aesthetic appearance of these mounting parts is improved. will not be damaged.

As is clear from the above description, according to the present invention, since the seat adjuster mounting portion is covered including the rail side, the aesthetic appearance of the seat adjuster mounting portion can be further enhanced. Further, since the bent upright piece is fitted and stored in the U-shaped groove of the lower rail, the cover does not get in the way when the upper rail slides.
