Abstract

PURPOSE:To simplify mounting construction of a cover, by mounting the end part of a rail assembly unit to a car body through a bracket, integrally forming cut-up pawls in the upper and lower of a mounting bolt hole of said bracket, while coating a mounting bolt with a cover, and forming a fitted part to said pawl in said cover. CONSTITUTION:A rail assembly unit, consisting of an upper rail 1 and a lower rail 2, slidably supporting the upper rail, is mounted to a car body 8 through a bracket 12 mounted to one end of the rail assembly unit. In this captioned construction pawls 15, 16, formed by the cutting up method, are molded as an integral unit to the upper and lower of a bolt hole 14 in a bracket 12. While fitted parts 18, 19, engaged to the pawls 15, 16, are formed to upper and lower parts of a cover 17 consisting of elastic material of synthetic resin and the like. Further side parts 21, 22, adapted to both side edges of the pawls 15, 16, are formed in both sides of an engagement part 20 to the pawls 15, 16 in said fitted parts 18, 19. In this way, the bracket 12 is fixed to the car body 8 by tightening a bolt 13, and then a head part of the bolt 13 can be easily further surely coated by the cover 17.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for a vehicle seat adjuster.

A vehicle seat adjuster is a seat adjuster attached to a seat S, as shown in Fig. 1 and Fig. C2.
A rail assembly consisting of a rail 1 and a lower rail 2 that slidably supports the rail, a bracket 3 being fixed to the end of the lower rail 2,
This bracket is made by Gerd 4! It is attached to panel 8. In the case shown in FIG. 1, since the center of the rail assembly and the center of the vehicle body attachment gel 4 coincide with each other, the leg space for rear seat occupants to put their feet in when they extend their legs is narrow. For this reason, as shown in FIG. 2, the lower part of the bracket 3 is shaped to project outward, and the outward projecting portion is attached to the vehicle body 8 through the bolt 4 to increase the leg space. It is being done.

3 and 4 are detailed views of a conventional mounting structure using the bracket shown in FIG. 2. To attach the rail assembly to the vehicle body, as described above, attach the bracket 3 to the gel plate 4.
This is done by fixing it to a cloth or flannel, but if it is left as it is, the head of the gelt 4 will be exposed and the appearance will be unsightly. For this reason, conventionally, a piece 5, which is a separate member, is welded to the bracket 3, bent pieces 7, 7 are formed on the top and bottom of the piece 5, and the bent pieces 7, 7 are used to Cover 6 is installed.

However, the installation of the conventional vehicle seat adjuster as described above involves welding a piece to the bracket that attaches the rail assembly to the vehicle body, and attaching the cover to this piece, which requires a large number of parts and requires piece processing. A welding process to the bracket is required, and furthermore, when welding the piece to the bracket, the piece may be misaligned or the bent piece for attaching the cover may be deformed, making it difficult to attach the cover. This may cause the cover to fall off.

The present invention has been made to improve the problems of the prior art as described above, and eliminates the use of pieces, and integrates the claws into one piece by cutting and raising the top and bottom of the gel insertion hole for mounting the bracket on the vehicle body. JP-A-58-20527 (2), which is characterized in that the cover is attached by using the tab.Hereinafter, an example of the implementation of the present invention will be described with reference to FIGS. 885 to 8.

First, to explain the configuration, the rail assembly Hiro, Ara Mother.
A bracket 12 is fixed to the end of the lower rail 11, and a bracket 12 is fixed to the end of the lower rail 11. Cut and raise the upper and lower parts of the vehicle body mounting bolt insertion holes 14.
5 and 16 are integrally formed. The cover 17 is molded from an elastic material such as synthetic resin, and has fitting parts 18 and 19 that engage with the claws 15 and 16 at its upper and lower parts. In addition, in the case of this embodiment, the fitting parts 18 and 19
As shown in an enlarged view in FIG. 8, side portions 21 and 22 are formed on both sides of the engaging portions of the tabs 5 and 16 to abut against both side edges of the tabs 15 and 16.

The vehicle seat adjuster mounting structure of the present invention has the above-described configuration, so that the bracket 12 fixed to the lower rail 11 of the rail assembly can be attached to the floor with the bolt 13. After attaching to the panel 8, fit the fitting portions 18 and 19 of the cover 1705 into the tabs 15 and 16 formed by cutting out the bracket 12.
30 heads can be covered and 17 can be covered.

In this case, if the fitting portions 18 and 19 are provided with side portions 21 and 22 as in the illustrated embodiment, the side portions 21 and 22
It comes into contact with both side edges of 5°16 to prevent the cover from shifting laterally. However, this point is not an essential requirement of the present invention. For example, the side end surface of the bracket 12 and the side wall of the cover 17 can be used to prevent the cover from shifting laterally.

As described above, according to the present invention, the claws 15.degree. 16 are formed by cutting and raising one racket 12, and the claws 15,
16 to attach the cover 17,
This eliminates the need for previously required pieces, reduces the number of υ parts, reduces weight accordingly, and eliminates the process of piece processing and welding the piece to the bracket, making positioning possible by piece welding. There is no misalignment or deformation of the bent piece, and these K have the effect of reducing costs and improving accuracy.
