Abstract

PROBLEM TO BE SOLVED: To keep sliding performance of an upper rail from being damaged by integrally connecting a pair of right and left lower rails at the front and the rear thereof to each other by connecting rods to be formed like a curb and providing a rising mechanism for fitting a seat cushion to one of the connecting rods in such a manner as to rise. SOLUTION: The front and rear parts of a pair of right and left lower rails are integrally connected to each other by a front connecting rod 12 and a rear connecting rod 13 to be formed like a curb. The front and rear connecting rods 11, 12 are formed to have a U-shaped section, and a rising mechanism 22 of a structure formed by a hinge, a return spring or the like is provided on the right and left of the front connecting rod 12. On the other hand, the rear connecting rod 13 is provided with a lock member 23 such as a latch or the like locked on a striker mounted on the car floor side and with a damper 24 resiliently pressed to the car floor. Thus, when the seat is used, it is kept from being deformed by a shock, so that the sliding performance of an upper rail 10 can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide device for adjusting the front / rear position of an automobile seat (seat), and more particularly, to a slide of a flip-up seat which can lift up a seat cushion in which a slide device is integrally incorporated. Related to the device.

[0002]

2. Description of the Related Art A seat in which a slide device is mounted so as to be able to jump up together with a seat cushion has an upper rail fixed to the left and right sides of the seat cushion as disclosed in, for example, Japanese Utility Model Laid-Open Publication No. 4-99138. The lower rail is slidably fitted to the upper rail, and a jumping-up mechanism is attached to the tip of each lower rail, and the lower rail is mounted on the vehicle floor.

[0003]

As described above, the above-mentioned conventional products are provided with a jumping-up mechanism at the tip of the lower rail and a locking mechanism at the rear end of the lower rail for locking toward the vehicle floor. Each of the lower rails is a long object having a narrow left-right width and a long length in the front-rear direction.

[0004] Therefore, a lifting mechanism for the lower rail,
Since the mountability of the lock mechanism is poor and the strength of the lower rail itself is insufficient, various reinforcing members are provided for reinforcement.

[0005] Therefore, the structure is complicated and the weight is increased, so that there is a problem that the sheet jumping operation cannot be performed smoothly.

Accordingly, an object of the present invention is to provide a slide device having a simple structure and a sufficient strength.

[0007]

According to the present invention, there is provided a slide device for a jumping seat, comprising: a pair of right and left upper rails fixed to a seat cushion;
It consists of a lower rail slidably fitted to each upper rail, and the pair of left and right lower rails are integrally connected in the front and rear with a connecting rod to form a cross-girder shape, and a seat cushion can be jumped up on one of the connecting rods. It is characterized by providing a jumping-up mechanism for attachment.

Accordingly, the left and right lower rails are reinforced by the connecting rods connected to the front and rear of the left and right lower rails, and the jumping-up mechanism can be mounted at any position of the connecting rods arranged in the left and right direction.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described.
This will be described with reference to the drawings. FIGS. 1, 2, and 3 show a slide device according to the present invention. In the drawings, (10) and (11) denote a pair of left and right lower rails, and front and rear of the lower rails (10) and (11) are connected to a front connecting rod (12). It is integrally connected by a rear connecting rod (13), and is formed in a grid shape as shown in FIG.

The front and rear connecting rods (12) and (13) are formed to have a substantially U-shaped cross section.
A jumping mechanism (22) (22) having a conventionally known structure including a hinge, a return spring, and the like is provided.

On the other hand, a locking member (2) such as a latch for locking to a striker provided on the vehicle floor side is provided on the rear connecting rod (13).
3), and a damper (24) which is in elastic contact with the vehicle floor is attached.

The upper rails (20) and (21) into which the lower rails (10) and (11) are slidably fitted.
Is fixed to a frame or the like of the seat cushion (SC), and a lock member (not shown) for locking to the lower rails (10) and (11) is provided on the left and right upper rails (20) and (21). The locked state by the lock member is determined by the operation handle (2) provided on the upper rail (21) side.
It is configured to be released by the operation force of 7). In the drawing, (28) indicates an interlocking wire that is connected to the operation handle (27) and releases the lock state provided by the lock member provided on the other upper rail (10).

The upper rails (20) and (21), the lower rails (10) and (11) which constitute the above-mentioned slide device,
As shown in FIG. 4, the front and rear connecting rods (12) and (13) are covered with a protective cover (30) made of resin so that the front and rear connecting rods (13) are not exposed to the outside when the seat cushion (SC) jumps up. .

In FIG. 4, (SB) in FIG. 4 indicates a seat cushion (S) by a reclining mechanism (4).
(C) the seat back superimposed on (C), (F) the vehicle floor on which the seat cushion (SC) is mounted so as to be able to jump up, (3)
1) shows a foam pad of the seat cushion (SC).

[0015]

As described above, the left and right lower rails slidably mounted on the upper rail are formed in a cross-girder shape by connecting the front and rear connecting rods. Therefore, since the seat is not deformed by the impact in the use state, the slidability of the upper rail is not impaired.

Further, the overall range of the lower rail can be lengthened to extend the sliding range of the upper rail, and the range of adjustment of the front and rear position of the seat can be increased as compared with the conventional product, thereby improving the usability of the seat. Can be.

In addition, since the jumping-up mechanism is mounted on the connecting rod, the mounting area of the jumping-up mechanism can be widened, and the mountability and mounting strength of the jumping-up mechanism can be improved.
