Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering an upper opening of a long rail which is suitable for largely adjusting the longitudinal movement of an automobile seat provided with a rotating mechanism. It relates to a mounting device. 2. Description of the Related Art In a long rail of this type, the rail opening is exposed to the floor of an automobile as the seat moves significantly back and forth, and not only does the appearance deteriorate, but also the rail opening increases. There is an inconvenience that dust and the like enter the rails, and a cover that does not hinder the operation is generally attached to the opening. In order to mount a cover for covering a long rail, which is generally used in the prior art, a plurality of longitudinal fitting grooves are provided on the upper surface and corners of the lower rail, and a projection from the cover body is slid into the fitting groove. Known are those fitted and fixed, and those covered by rubber vulcanization and baking on the outside of the lower rail. [0004] In the above-mentioned conventionally known cover mounting method, the former fixing method of slidingly fitting a projection into the fitting groove is to insert the projection from the cover body from one end of the fitting groove. The insertion is troublesome and inefficient, and the latter has a problem in terms of equipment and the like. [0005] In order to solve the above-mentioned conventional problems, the present invention provides a channel-shaped, lower rail having a long channel-like shape and a rectangular cross-section having a groove in the center longitudinal direction of the upper surface. Along the lower rail, a long rail consisting of a sub-guide having a longitudinal opening at the top is formed of a soft resin and a hard resin. The thin portion is covered in correspondence with the groove and the opening, and the hard resin of the cover body is locked with a plate spring provided at the lower part of the lower rail and wrapped, and then the center of the thin portion is cut out, It is provided for the purpose of simplifying the mounting of the cover body. The lower rail 1 having a groove 1a in the center on the upper surface side
And a long rail in which the sub-guides 2 integrally provided with the openings 2a along the lower rails 1 are arranged and fixed by appropriate means such as welding.
a and the soft resin a of the cover body 4 to cover the thin portion of the cover body 4 so as to be opposed to each other, and at the end, a leaf spring 3 that is surrounded by a hook receiving portion 4a provided on the side surface of the hard resin b through the bottom of the lower rail 1. It is molded, the locking part 3b is locked and wrapped and fixed,
A notch 4b is formed at the center of a thin portion of the cover body 4 which is fixedly attached and which faces the groove 1a and the opening 2a by using a cutting tool. FIG. 1 shows an embodiment of an apparatus for attaching a cover for a long rail according to the present invention, which will be specifically described below with reference to the drawings. Reference numeral 1 denotes a long channel-shaped lower rail having a rectangular cross section having a groove 1a in the center longitudinal direction of the upper surface, which is fixed to the floor. One side of the lower rail 1 has a sub-guide having a rotating seat structure. 2 are arranged side by side, fixed by appropriate means such as welding, and provided integrally. The upper part of the sub-guide 2 is provided with an opening 2a in the longitudinal direction, and the bottom surface 2b is provided with a plurality of holes 2c through which the branch spring 3a of the leaf spring 3 passes when the cover body 4 is locked. is there. The cover body 4 covers the upper surface of the lower rail 1 and the sub-guide 2 and is formed by simultaneously molding a soft synthetic resin a and a hard synthetic resin b. A locking receiving portion 4a for locking a locking portion 3b formed at an end of the leaf spring 3 is formed and provided, and the soft synthetic resin a is used to cover the lower rail 1 and the sub-guide 2 to the cover body 4.
When it is covered by the above, the portion corresponding to the groove 1a and the opening 2a is formed so as to be slightly thin, and this thin portion is covered with the cover body 4 and fixed to the lower rail 1 and the sub-guide 2 by the leaf spring 3. A notch 4b is formed by the rear blade. As described above, in the cover mounting apparatus of the present invention, since the cover body is formed simultaneously with the hard and soft synthetic resin, the formation can be simplified, and the cover body is wrapped by the rear leaf spring covering the lower rail and the sub guide. Since the structure is such that it is engaged and locked, the structure is simple and the cover can be easily attached. In addition, even if the cover is damaged by long-term use, the cover can be replaced and replaced, and there is no need to replace the rail body, which has an economic advantage.
