 The present invention relates to a power seat switch suitable for use in a seat of an automobile, for example.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in vehicle seats, so-called power seat devices have been widely used in which, for example, a seat cushion slide operation in the front-rear direction and a seat cushion lifter operation in the up-down direction are performed electrically.

In this type of power seat device, a predetermined adjustment operation is made possible by operating an operation switch provided on a side portion of the seat to operate an electric motor built in the seat.

As a mounting position of the above-mentioned operation switch, generally, the operation switch is installed at a predetermined position of the finisher arranged on the side portion of the seat cushion or directly on the side portion of the seat back. There is something I did.

On the other hand, in addition to the operation switches of the power seat device described above, there is a so-called reclining device in which the seat back is rotatable in the front-rear direction with respect to the seat cushion. Some of the reclining devices can be electrically operated as in the case of the power seat device, but in the case of the reclining device, generally, a reclining device in which the adjusting dial is manually rotated to perform the reclining operation is widely used. The position where the adjustment dial of this reclining device is attached is provided in the vicinity of the pivotal support shaft portion of the seat back, which is behind the side portion of the seat cushion, in addition to the operation switch of the power seat device described above.

[0006]

As described above, since the operation switch of the conventional power seat device and the adjustment dial of the reclining device are separately arranged, the driver operates the power seat device while seated on the seat. The position of the switch had to be searched for each time, so it took a long time to operate and it was uncomfortable.

The present invention has been made to solve the above-mentioned problems, and facilitates the operation of a power switch for sliding the seat cushion in the front-rear direction and lifting the seat cushion in the up-down direction. The purpose is to obtain the power seat switch for the seat.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the power seat switch for a seat according to the present invention is provided with a reclining adjustment dial on the seat cushion side for reclining the seat back with respect to the seat cushion, and the seat cushion is provided on the reclining dial. It is equipped with a lifter switch and a seat cushion front-back slide switch.

[0009]

[Action]

 The power seat switch for a seat according to the present invention configured as described above includes the seat cushion lifter switch and the seat cushion forward / backward slide switch in the reclining adjustment dial, so that the seat back reclining operation is performed at the operation dial position. The power switch for sliding and lifting the seat cushion can be operated, improving operability.

[0010]

【Example】

 Hereinafter, embodiments of a power seat switch for a seat according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an overall perspective view of a seat for a seat. In the figure, reference numeral 1 indicates a seat cushion, and 2 indicates a seat back. Reference numeral 3 is a reclining adjustment dial of the seat back 2 provided on the rear side of the seat cushion 1. By rotating the reclining adjustment dial 3, the seat back 2 can be reclined in the front-rear direction via a reclining mechanism (not shown) built into the seat cushion 1.

FIG. 2 shows a front view of the reclining adjustment dial 3 described above, and FIG. 3 shows a sectional view taken along the line AA of FIG. 2 and 3, the side surface of the reclining adjustment dial 3 is formed in a recess 4, and the recess 4 accommodates the power switch body 7 of the seat cushion lifter switch 5 and the seat cushion front-back slide switch 6.

The power switch main body 7 has its shaft portion 7 a inserted and supported in the rotary shaft 3 a of the reclining adjustment dial 3 described above. Therefore, the reclining adjustment dial 3 is rotated, but the power switch body 7 is not rotated.

The seat cushion lifter switch 5 includes a seat cushion upper movement lifter switch 5 a on the upper surface of the power switch body 7 and a seat cushion lower movement lifter switch 5 b on the lower surface of the power switch body 7.

Further, the seat cushion forward / backward slide switch 6 is provided with a seat cushion advance switch 6a on the front surface of the power switch body 7 and a seat cushion retreat switch 6b on the rear surface of the power switch body 7.

Each of the above-mentioned switches 5a, 5b and 6a, 6b is a push-type switch, and hereinafter, referring to FIG. 4 with reference to the switch 5a, a movable contact 8 is provided on the back surface of the switch 5a. The movable contact 8 faces a fixed contact 9 provided on the switch body 7 side, and is spring-supported by a coil spring 10. Therefore, when the switch 5a is pressed against the coil spring 10, the movable contact 8 electrically contacts the fixed contact 9 on the switch body 7 side to perform the switch operation.

In the switch 5a, the movement of the seat cushion 1 is continuously performed during the switch operation, and when the finger is released from the switch 5a, the switch operation is interrupted by the spring restoring force of the coil spring 10 and the seat cushion 1 The movement operation of stops.

The electrical wiring 11 of each of the switches 5a, 5b and 6a, 6b described above is connected to an electric motor (not shown) arranged in the seat cushion 1 through the shaft portion 7a of the switch body 7.

The power seat switch according to the present invention thus configured is integrated with the reclining adjustment dial 3 of the seat back 2, so that the reclining operation of the seat back 2 by rotating the reclining adjustment dial 3 is performed. By operating the seat cushion lifter switch 5 and the seat cushion front and rear slide switch 6 provided in the reclining adjustment dial 3, the lifter operation and the slide operation of the seat cushion 1 can be performed.

Further, the seat cushion lifter switch 5 and the seat cushion front / rear slide switch 6 are arranged such that the switches in the respective moving directions correspond to the positions of the side surfaces of the reclining adjustment dial 3, so that the driver It is possible to operate the switch without checking the switch in the direction in which it is operated.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

For example, although the seat cushion lifter switch 5 and the seat cushion front / rear slide switch 6 are configured as four independent switches in the embodiments, the seat cushion lifter switch 5 and the seat cushion lifter switch 5 have been described. The cushion front-back slide switch 6 and the cushion front-back slide switch 6 may be configured as seesaw-shaped switches.
