Abstract

PROBLEM TO BE SOLVED: To prevent leak of grease through a slit of a cover and to prevent the intrusion of solid material into a lower rail by forming a part of a cover facing to an opening part of a lower rail of outer sealing pieces and inner sealing pieces in the vertical direction so as to face to the slit. SOLUTION: Covers 3, 4 respectively having a slit at a central part thereof are made of a soft elastic synthetic resin, and a part of the covers over an opening part 11 of a lower rail 1 is integrally formed with two stages in the vertical direction. A lower stage is formed with inner sealing pieces 30, 40 and an upper stage is formed with outer sealing pieces 31, 41, and each piece is arranged so as to face to each other. The inner sealing pieces 30, 40 and the outer sealing pieces 31, 41 of the covers 3, 4 are formed along the longitudinal direction of the opening part 11 of the lower rail 1, and a part of the upper rail 2, which is not fitted in the lower rail 1, is fitted so that a tip edges of the left and right inner sealing pieces 30, 40 and the outer sealing pieces 31, 41 contact with each other. With this structure, leak of the, grease from inside of the lower rail 1 and intrusion of the solid material from outside can be regulated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail for adjusting the front / rear position of a vehicle seat such as an automobile seat (seat). The present invention relates to a cover made of a flexible elastic material for closing a portion.

[0002]

2. Description of the Related Art Conventional slide rails include an upper rail for mounting and fixing a seat, and a lower rail for slidably fitting the upper rail along an opening provided on an upper surface thereof and fixing the upper rail to a vehicle floor. There is a cover made of a flexible elastic material having a slit fixed to the outer surface of the upper surface of the lower rail to close the opening and insert the upper rail.

[0003] The above cover prevents the entry of dust and dirt into the lower rail from the opening and improves the appearance quality of the slide rail.

[0004]

By the way, a sliding material such as grease is mounted in the lower rail in order to improve the sliding property of the upper rail.

Therefore, there is a problem that grease leaks outside through the slit of the cover due to the sliding of the upper rail in the front-rear direction.

Further, since the cover has soft elasticity, there is a possibility that solid matter easily enters the lower rail through the slit of the cover.

Accordingly, an object of the present invention is to eliminate the problem of the cover made of a flexible elastic material that closes the opening of the lower rail.

[0008]

A slide rail according to the present invention for achieving the above object is characterized in that a portion of the cover located at the opening of the lower rail is formed by vertically closing an outer closing piece and an inner closing piece. Are arranged so as to face the slit, and the opening of the lower rail is completely closed by the cover.

[0009]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a slide rail according to the present invention, in which (1) is a lower rail embedded and fixed in a concave groove of a vehicle floor (6), and an opening (11) is formed on an upper surface (10) (1).
0) is formed in a substantially channel-shaped cross section.

The opening (11) of the lower rail (1)
Are closed by covers (3) and (4) fixed to the mounting members (12) and (12), as shown in FIG. The mounting members (12) (12) are provided on the upper surface (1) of the lower rail (1).
0) and (10).

In the drawing, reference numeral (2) denotes an upper rail slidably fitted to the lower rail (1). A sheet is placed or fixed on the upper rail (2), and a pair of left and right rollers (20) provided in the front and rear directions. (20) is fitted in the lower rail (1) as shown in FIG.

The covers (3) and (4) having the slit (5) at the center are made of a synthetic resin material having soft elasticity.
As shown in the figure, the portion located above the opening (11) of the lower rail (1) is integrally formed in a vertical and two-stage manner, and the lower side is an inner closing piece (30) (40), and the upper side is an outer part. Closing pieces (31) and (41), inner closing pieces (30) and (40) and outer closing pieces (31) and (4) of left and right covers (3) and (4).
1) is disposed to face each other.

The inner closing pieces (30) and (40) and the outer closing pieces (31) and (41) of the covers (3) and (4) extend in the longitudinal direction of the opening (11) of the lower rail (1). The upper rail (2) is formed integrally along the lower rail (1), as shown in FIG.
Left and right inner closing pieces (30) and (40), outer closing pieces (3
1) It is attached so that the leading edge with (41) is joined.

Then, as shown in FIG. 3, the portion where the upper rail (2) is fitted to the lower rail (1) comes into contact with the vertical wall surface of the upper rail (2) so that the inner closing piece ( 30) (40) and outer closure piece (31 (41)
Are formed.

As shown in FIG. 4, the inner closing piece (3
0 ') and (40') may be formed such that the amount of protrusion in the direction of the slit (5) is shorter than that of the outer closing piece (31) (41).

[0016]

According to the present invention, the grease does not leak out from the inside of the lower rail due to the double closing structure of the opening and the outer closing piece in the cover.
In addition, it is possible to restrict intrusion of solid matter from the outside into the lower rail.
