Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield member for protecting a mechanism of a vehicle electric seat apparatus.

[0002]

2. Related Background Art As shown in FIG. 9, an electric seat device 1 for a vehicle such as an automobile is provided with a seat adjuster 2 fixed to a floor panel (not shown) of a vehicle body and an upper portion of the adjuster 2. Seat cushion 3,
It is attached to the rear end of the adjuster 2 and comprises a tiltable seat back 4 and the like.

[0003] Generally, such an electric seat device 1 is used to adjust the attitude of the electric seat device in order to make it easier for the driver to drive.
That is, the position of the seat cushion 3 can be adjusted in the front-rear direction and the vertical direction of the vehicle, and the angle of the seat back 4 can be adjusted. Then, instead of manually adjusting these positions and angles, a plurality of motors attached to the seat adjuster 2 and the like are driven to perform the adjustment.

The seat adjuster 2 of the electric seat apparatus 1 includes a slide motor 2a for moving the seat cushion 3 in the vehicle front-rear direction, a front vertical motor 2b for moving the front portion of the seat cushion 3 up and down, and a rear portion of the seat cushion 3. And a reclining motor 2d for adjusting the inclination angle of the seat back 4 are attached.
A lumbar support motor 4b for rotating the lumbar support bar 4a is mounted inside the seat back 4 of the electric seat device 1. The torque of these motors is used to adjust the electric seat device 1 to a desired posture via a known power transmission mechanism.

As shown in FIG. 11, an electronic control unit (hereinafter, referred to as “ECU”) 5 may be further mounted on the seat adjuster 2. The ECU 5 is a unit mounted with a position memory for storing at least one driver's seat position and a CPU for adjusting and controlling the electric seat device to a desired posture using the memory value.

An operation switch 6 for sending a control signal to the ECU 5 is mounted on the side of the seat adjuster 2 via a mounting bracket (not shown). The operation switch 6, the ECU 5, and the motors 2a to 2d and 4b are shown in FIG. 11
As shown in FIG. 1, the seat is electrically connected by a seat wire harness 7 arranged in the electric seat apparatus 1. Further, an elongated plate-shaped resin shield member 8 as shown in FIG. 9 or an L-shaped resin shield member 9 as shown in FIG. 10 is attached to the lower side surface or the front surface of the seat adjuster 2. The shield members 8 and 9 cover the mechanism of the electric seat apparatus 1 and serve to protect the mechanism from external impact, dust and dirt.

[0007]

In assembling the above-described electric seat apparatus 1, as shown in FIG. 11, an operation switch 6 is attached to the seat adjuster 2, and a seat wire harness 7 is connected from the operation switch 6 to the ECU 5 and each motor. Requires work to route. In this wiring work, the seat wire harness 7 is crawled from the operation switch 6 along the side of the seat adjuster 2 to the front end of the adjuster 2, and from there, is wired to the ECU 5 or each motor arranged inside the adjuster 2. This is commonly done. Therefore, after that, the shielding member 8
When attaching the shield member 8, the user must work while paying attention so that the sheet wire harness 7 does not protrude from the shield member 8.

On the other hand, in the case of an electric seat device having a seat position memory function, the ECU 5 occupies a part of the space formed in the adjuster 2 because the ECU 5 is attached to the seat adjuster 2. Therefore, for example, a passenger in the rear seat of the electric seat device 1 can relax his / her legs by entering the space below the electric seat device, that is, the space formed in the seat adjuster 2, or use this space as a luggage space. I can't do that.

Japanese Patent Application Laid-Open No. 58-76335 is known as a conventional technique for forming a space below the electric seat apparatus 1. This is an electronic control unit (ECU described above) that controls the driving of the seat attitude setting mechanism (each of the above-described motors).
Is housed inside the seat back of the electric seat device. By arranging the electronic control device in such a place, so-called space saving can be achieved, and the lower portion of the electric seat device can be effectively used as a space.

However, in such a configuration, the operation switch 6
The distance between the ECU, the ECU 5 and each motor increases, and the overall length of the seat wire harness 7 for establishing electrical connection between them also becomes very long. In the case of an electric seat device with a position memory function, five electric wires (2
In addition to the three power supply lines, the connection of the three position sensors is required, so that the seat wire harness 7 is required.
Is also very thick throughout. As a result, when the ECU 5 is stored inside the seat back, a very thick seat wire harness 7 is routed between the seat cushion 3 and the seat back 4, and every time the seat back 4 tilts, the seat wire harness 7 Is bent, and if the electric seat device 1 is used for a long period of time, there is a possibility that the electric wire will be disconnected or short-circuited.

An object of the present invention is to provide a shield member of a vehicle electric seat device which reduces the number of assembling steps of the vehicle electric seat device. It is a further object of the present invention to provide a shield member for a vehicle electric seat device that can reduce the number of assembling steps of the vehicle electric seat device and can effectively use the space below the electric seat device.

[0012]

According to the present invention, there is provided a shield member for a vehicle electric seat device according to the present invention, wherein a shield member for protecting a mechanism including a motor device for adjusting the attitude of the electric seat device controls operation of the electric device. The control part is housed, and a conductive wire electrically connected to the control part is led out from a predetermined part toward the mechanism part.

[0013] Since the control component is housed in the shield member, the shield member and the control component can be attached to the electric seat device at the same time, thereby reducing the number of assembling steps of the electric seat device. Further, since the harness (conductive wire) is integrated with the shield member and is electrically connected to the control component, the wiring of the harness in this portion is completed by attaching the shield member to the electric seat device. In addition, the number of steps for assembling the electric seat device is reduced.

[0014] A shield member according to another embodiment of the present invention stores at least one position of an electric seat device,
A control unit for outputting a control signal for moving the electric seat device to a predetermined position in accordance with the selected stored value, and an operation for electrically connecting the control unit to one end face of the control unit and sending the control signal to the control unit A control component including a switch is housed in a recess formed in the shield member.

Since the control component including the control unit and the operation switch is housed in the shield member, the wiring work of the harness between the control unit and the operation switch becomes unnecessary.
Further, the space below the electric seat device, which has conventionally been occupied by the control unit, is vacant, and this space can be effectively used as a luggage space.
