Description

[Detailed description of the invention] The present invention relates to an improvement in the attachment structure of the interlocking wire of the locking mechanism in the seat slide device of a bench seat installed in an automobile, etc. It is an object of the present invention to provide a mounting structure in which the interlocking wire is not affected even if the position of the seat cushion frame is displaced forward or backward due to an impact such as a shift of body weight.

Generally, in the seat sliding device of bench seat,
By operating a single adjuster lever, the locking mechanisms of the seat slide devices at the bottom of both sides of the seat cushion are interlocked, changing from a locked state to an unlocked state.

As shown in Fig. 6, its standard structure includes seat tracks B at the bottom of both sides of the seat cushion frame A;
Upper rails D and E of C are fixed, and lower rail F
, G, and is configured to be locked at a selected position by locking mechanisms H and I, and the locking mechanism H
, I are configured such that when the locking mechanism H is unlocked by the adjuster lever J, the operation thereof is transmitted to the other locking mechanism I by the interlocking wire K, so that the locking of the mechanism I is released.

By the way, in automobiles, especially passenger cars, a tunnel is formed in the floor, and in order to cross this tunnel, it is necessary to hold the interlocking wire in a state in which its central portion is lifted upward.

For this reason, conventionally, a structure has been adopted in which a forward-facing hook-shaped hanging part M is provided on the central lower part of the seat cushion frame A, and the central part of the interlocking wire is hooked onto this.

However, with this structure, when the seat cushion frame A is displaced toward the front of the seat as shown by arrow The hook was fixed.
Since it is pushed in the direction of arrow X, it is in a pulled state and has the drawback that the lock mechanisms H and I are unlocked.

The present invention provides an interlocking wire attachment structure for a locking mechanism in a seat slide device that does not have the above-mentioned drawbacks by having the configuration described in the claims of the utility model registration.

The configuration of the illustrated example will be explained below.

1, 2, and 3 show a first embodiment, in which upper rails 4.5 of seat tracks 2 and 3 are fixed to the lower portions of both sides of a seat cushion frame 1, and lower rails 6. 7, due to the lock mechanisms 8 and 9,
It is configured to be inserted at a selected location.

When the locking mechanism 8 is unlocked by the adjuster lever 10, the operation of the locking mechanism 8, 9 is transmitted to the other locking mechanism 9 by the interlocking wire 11.
is configured to unlock the

A support 13 is vertically installed on the frame member 12 at the lower center of the seat cushion frame 1, and the interlocking wire 11 is inserted into a transparent window 14 formed in the support and long in the seat longitudinal direction. The support member 13 is supported by the lower side 15 of the floor 16 at a position above the tunnel portion 17 .

The illustrated support 13 has a metal rod bent into a substantially U-shape,
It is welded to the frame member 12 at both ends.

Now, when the seat cushion frame 1 is displaced toward the front of the seat as shown by arrow The tool 13 moves in the direction of the arrow X to the position indicated by the chain line 13', but the interlocking wire 1
1 is located within the transparent window 14, so it maintains its old position regardless of the displacement of the support 13 and is not subjected to any pressure from the support. No unlocking occurs.

FIG. 4 shows another embodiment of the support device 18.
is a narrow metal plate bent into a flat U-shape with both ends 19.2
0, and the interlocking wire 22 is inserted into the transparent window 23 in the same way as the support 13 of the embodiment shown in FIGS. 1 and 3.

FIG. 5 shows another embodiment of the support 24.
A part of the frame member 25 is cut out by drawing, and the interlocking wire 27 is inserted into the transparent window 26, as in the embodiment shown in FIG.

The interlocking wire mounting structure according to the present invention has the configuration and operation described above, and the interlocking wire is installed in a transparent window that is long in the front and back direction of the seat in a support that is hung vertically at the lower center of the seat cushion frame. Because it is inserted through the seat cushion frame, it is held in an upper position where it does not interfere with the tunnel part of the floor, and when the seat cushion frame is displaced due to an impact such as the weight of the occupant or the shift of the weight of the occupant during brake operation, the transparent Due to the action of the window, the old position can be maintained without coming into contact with the support, which has the effect of preventing unexpected unlocking, and the structure is extremely simple, so it does not increase weight or cost. It also has the effect of not having any.
