Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat harness for a harness, such as a seat heater or an air bag, in a seat back which can be drawn out from the side of the seat back so as to be attractive and to prevent disconnection. Stop structure.

[0002]

2. Description of the Related Art Generally, an automobile seat is shown in FIG.
As shown in FIG. 1, the seat cushion 1 and the seat back 2 are provided, and the seat back 2 is supported on the seat cushion 1 so as to be reclined by a hinge bracket.

When a seat heater, an air bag, a lumbar support, and the like are incorporated in the seat back 2, these harnesses, air tubes, wires, etc. (hereinafter, referred to as harnesses) 3 are drawn out to the outside. Must be connected to control components.

For this reason, conventionally, the harnesses 3 of the seat back 2 are pulled out from the back of the seat back 2 to the outside, the notches 4 of the seat cushion 1 are passed, and the cover 5 covering the harnesses 3 is attached to the seat. There is one attached to the rear of the back 2 (see Japanese Utility Model Publication No. 1-8428).

[0005]

However, FIG.
As shown in (B), when it is necessary to pull out the harnesses 3 from the side, not from the back of the seat back 2, the harnesses 3 look good so that the slackness of the harnesses 3 does not vary, and the bending fatigue occurs. Therefore, it is necessary to renew the device for drawing out to the outside so as to prevent disconnection.

SUMMARY OF THE INVENTION The present invention has been made in order to meet the above-mentioned demands, and harnesses such as a seat heater and an air bag in a seat back can be drawn out from the side of the seat back so as to be attractive and to prevent disconnection. It is an object of the present invention to provide a seat harness locking structure as described above.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a seat cushion in which a seat back is supported by a hinge bracket so as to be reclined by a hinge bracket. The harnesses such as the back are pulled out to the outside. The harnesses are pulled out along the synthetic resin cover of the hinge bracket, and are integrally formed at a position near the hinge center of the cover. A harness locking structure for a seat, characterized in that the harness is provided with a slack at the front and rear positions of the tying member so as to be able to absorb the tension generated by reclining or sliding. .

According to the present invention, the harnesses of the seat back are pulled out along the cover of the hinge bracket on the side surface of the seat back, and the locking portion near the hinge center of the cover has slack. And binding with the binding device, the movement of the harness due to reclining and sliding of the seat is small, and the bending fatigue is reduced, so that disconnection is less likely to occur and the looseness of the harness is hard to vary, so the appearance is also good .

Preferably, the cover is a hinge cover outside the hinge bracket or a reverse cover inside the hinge bracket.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. The parts having the same configuration and operation as those of the prior art in FIG. 3 are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 shows a first embodiment in which the harness 3 is locked to a hinge cover 7A that covers the outside of the hinge bracket 8 on the seat back 2 side.

The hinge cover 7A is formed of a synthetic resin and covers the outside of a hinge bracket 8 that supports the seat back 2 so that the seat back 2 can be reclined with respect to the seat cushion 1.

At the position near the center hinge 9 on the outer surface of the hinge cover 7A, an engaging portion 7a projecting outward in a substantially U-shape is integrally formed.

On the other hand, the tying member 10 of the harnesses 3 engages with one of the saw-tooth grooves when the belt portion 10a is inserted into the rear portion of the belt portion 10a in which the width-direction saw-tooth grooves are formed. A locking block 10b having a pawl is provided,
By changing the locking position of the belt portion 10a by the locking block 10b, a known device that can freely adjust the binding diameter of the belt portion 10a can be used. Note that a binding device such as a soft wire or a binding device such as a string may be used.

Then, the harnesses 3 from the seat back 2 are pulled out to the outside along the hinge cover 7A, and are locked to the locking portions 7a of the hinge cover 7A using the binding device 10. At the time of this locking, the harnesses 3
At the front and rear positions of 0, care is taken to provide slacks A and B that can absorb the tension generated by reclining or sliding.

In the first embodiment, the binding device 1 is attached to the locking portion 7a of the hinge cover 7A near the center hinge 9.
Since the harnesses 3 are locked by 0, the movement of the harness due to the reclining and sliding of the seat back 2 and the seat cushion 1 is reduced, and the bending fatigue of the locking portion is reduced, so that disconnection is less likely to occur. Further, since the slacks A and B at the front and rear positions of the locking portions of the harnesses 3 are hard to vary, the appearance is also improved.

FIG. 2 shows a second embodiment in which the harness 3 is locked to a reverse cover 7B which covers the inside of the hinge bracket 8 on the seat cushion 1 side.

The reverse cover 7B is formed of a synthetic resin, and the reverse cover 7B is
To cover the inside of the hinge bracket 8 that supports so as to be able to recline.

At a position near the center hinge 9 on the inner surface of the reverse cover 7B, an engaging portion 7a projecting outward in a substantially U-shape is integrally formed.

Then, the harnesses 3 from the seat back 2 are pulled out to the outside along the reverse cover 7B,
As in the first embodiment, the locking portion 7 of the reverse cover 7B
a using the tying tool 10 to lock it.
The harnesses 3 are designed to have slacks A and B at the front and rear positions of the tying member 10 that can absorb the tension generated by reclining and sliding.

In the second embodiment, the harnesses 3 are locked by the binding device 10 to the locking portions 7a of the reverse cover 7B near the center hinge 9, so that the seat back 2 and the seat cushion 1 The movement of the harness due to reclining and sliding is reduced, and the bending fatigue of the locking portion is reduced, so that disconnection is less likely to occur. Further, since the slacks A and B at the front and rear positions of the locking portions of the harnesses 3 are hard to vary, the appearance is also improved.

[0022]

As is apparent from the above description, in the harness locking structure of the present invention, the harnesses of the seat back are pulled out to the outside along the cover of the hinge bracket on the side surface of the seat back, and the hinge center. The cover's locking part close to the slack is loosened and locked with a tying tool, so less movement of the harness due to reclining and sliding of the seat reduces bending fatigue, so disconnection is less likely to occur At the same time, since the slack of the harness is hard to vary, the appearance also becomes good.
