Abstract

PROBLEM TO BE SOLVED: To reduce the number of part items and fitting man-hours by providing a seat fixing pedestal bend-extended from a front and a rear vertex of a runner, of which lower part is fitted in a lower rail, and notching a lower part of a supporting part, extending form a vertex of the runner with a through hole for insertion of a lock piece, so that the lock piece can be fitted therein freely slidable in the vertical direction. SOLUTION: Multiple lock holes 21, with which lock teeth 31 of a lock piece 3 are to be engaged, are opened in a bottom surface of a lower rail 2 in the longitudinal direction thereof. An upper rail 1 has a runner 10 formed of a vertical plate, and a lower part thereof is fitted in the lower rail 2. A front and a rear vertex parts of the runner 10 are respectively provided with a seat fixing pedestal 11, which is bent at a right angle for extension, and a nearly central part of the runner 10 in the longitudinal direction is provided with a supporting piece 12, which is similarly extended with the runner, and a through hole 12A for a vertex of the lock piece 3 is opened. A notch part 13 having the nearly same fore and aft directional width with the lock piece 3 is vertically notched in the runner 10 under the supporting piece 12, and the lock piece 3 is housed in the notch part 13 freely slidable in the vertical direction. The number of part items is reduced by integral forming, and the structure is simplified, and productivity is improved.

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.

Conventional slide rails include a lower rail fixed to the vehicle floor side and an upper rail having a lock piece slidably fitted to the fixed rail and engaged with the lower rail.

A mounting bracket is welded to the upper rail, and a seat is fixed to the mounting bracket. A lock piece provided on the upper rail side for locking the upper rail to the lower rail is supported by a support member fastened to the upper rail.

[0004]

Therefore, in the conventional product, the fixing member for the seat and the supporting member for the lock piece are separately formed on the upper rail, and are attached to the upper rail. For this reason, the number of parts is increased, and there is a problem that the man-hour for mounting to the upper rail is required.

Accordingly, an object of the present invention is to eliminate such a disadvantage of the conventional slide rail.

[0006]

According to the present invention, there is provided a slide rail comprising: a vertical runner having a lower part fitted in a lower rail; and a front and rear top part of the runner. A seat fixing pedestal that is bent and extended more perpendicularly, and a support piece that has a through hole that is bent and extended perpendicularly from the top of the runner and penetrates the lock piece vertically. And a notch portion in which the runner below the support piece portion is cut out in the vertical direction and the lock piece is slidably fitted in the vertical direction, and the seat is fixed to the seat fixing base. The lock piece is vertically slidable in the notch, and the upper part is guided by the through hole of the support piece.

Further, a substantially V-shaped locking piece is integrally provided at the lower end of the runner, and a guide hole for inserting the locking piece is provided in the locking piece, so that the upper and lower portions of the locking piece are guided. , Slides up and down, back and forth, left and right without rattling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In the drawing, (1) shows an upper rail having a lock piece (3), (2) shows a lower rail fixed to the vehicle floor side, and a lock of the lock piece (3) is provided at the bottom of the lower rail (2) in the longitudinal direction. A large number of lock holes (21) are engaged with the teeth (31).

The upper rail (1) has a runner (10) composed of a vertical plate.
The lower part of (0) is inserted into the lower rail (2), and a pair of left and right rollers (14) (14) that roll in the lower rail (2) is mounted on the front and rear of the inserted part.

In front of and behind the runner (10), seat fixing pedestals (11) and (11) are provided which are bent at right angles to the runner (10) and extended. (11) Bolts (11A) (11)
A) protrudes. This bolt (11A) (11
By fastening the seat (seat cushion) placed on the pedestals (11) and (11) in A), the seat is fixed to the upper rail (1).

The runner (1) is located substantially at the center of the runner (10) in the longitudinal direction, similarly to the pedestals (11) and (11).
0) is provided with a support piece (12) which is bent at right angles and extended, and this support piece (12) slides vertically on the top (30) of the lock piece (3). A through hole (12A) is freely inserted.

The runner (10) located below the support piece (12) has a notch (13) cut out substantially the same as the front-rear width of the lock piece (3). The front and rear edges of the lock piece (3) are supported in the notch (13). Therefore, the lock piece (3) is slidably housed in the notch (13) in the up-down direction and the top (3).
0) is supported by the support piece (12).

The lower end of the runner (10) has a runner (1).
A substantially V-shaped locking piece (4) for preventing peeling of the lower rail (2) from the lower rail (2) is welded upward as shown in FIG.

The notch (1) in the locking piece (4)
Insert the lock piece (3) into the part corresponding to 3),
An opening (41) for supporting the lower part of the lock piece (3) is opened.

Therefore, the lower part of the lock piece (3) has a through hole (41) for the locking piece (4), and the top part (30) has a support piece (1).
2), each slides smoothly in the vertical direction, and the lock teeth (31) provided at the lower end of the lock piece (3) are locked by the lock holes (2) of the lower rail (2).
Disengage securely in 1).

In the drawings, (14) and (14) denote a pair of left and right rollers axially mounted on the front and rear of the runner (10).
2) indicates unlock levers, respectively.

[0017]

According to the present invention, since the upper rail is integrally formed with the support piece and the notch for mounting the seat fixing pedestal and the lock piece, the mounting bracket and the lock for seat fixing are formed as in the prior art. There is no need to separately manufacture a support member or the like for one-sided attachment and attach it to the upper rail.

[0018] Therefore, the structure can be simplified by reducing the number of parts of the slide rail, and a slide rail which does not easily break down can be provided. Further, productivity can be improved and manufacturing can be performed at low cost.
