Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power seat switch assembly in which various operation switches for driving and controlling a power seat motor are arranged.

[0002]

2. Description of the Related Art For example, a so-called power seat equipped with various seating posture control devices operable under the drive of a motor by corresponding switch operation is used as a driver seat for passenger cars, It is provided as an assistant seat.

Generally, a motor of a power seat is connected to a motor control device having a microcomputer and the like, and can be drive-controlled by switching operation of a corresponding operation switch provided in the motor control device. The operation switch is usually grouped as a switch assembly for each seat and is provided at a position where a seated person can operate, such as a side of a seat cushion of the seat.

In such a structure, the seat position corresponding to the body shape and taste of the seated person and the use of the seat is set by the operation of the sitting posture control device under the drive control of the motor in accordance with the corresponding switch operation. It can be easily adjusted and set, ensuring sufficient comfort and safety for the occupant.

[0005]

By the way, in recent power seats, it has been attempted to further improve the comfort of the seated person by diversifying the seating posture control device provided side by side with one seat and increasing the number of functions such as memory. Tend to do. However, when the seating posture control device is diversified and has multiple functions, a corresponding number of operation switches are required, so the number of operation switches for each seat increases, and the switch assembly for each seat tends to increase in size. .

Here, in the known structure, since the switch assembly is provided on the side of the seat cushion for each seat, the seat cushion is required to have a large space for the switch assembly. However, since the space that can be secured is limited on the side of the seat cushion, if the switch assembly becomes large, the cushion portion may be adversely affected and the cushioning property may be deteriorated.

Further, since the driver seat and the assistant seat are provided with respective operation switches, it is unavoidable that the structure is complicated and the cost is increased due to the increase in the number of parts.

Further, with the operation switch provided on the side of the seat cushion, it is easy to feel the operation. However, when the number of operation switches increases due to the multifunctionalization of seats and the like, it is difficult to distinguish the operation switches in a fumbling switch operation, and it is inevitable that the switch operation becomes complicated.

If the switch operation is complicated, not only the operability of the switch is deteriorated, but also erroneous operation may be caused.

Here, focusing on the center console between the driver seat and the assistant seat, it is possible to secure good operability by disposing the operation switch on the center console. However, if it is attempted to arrange all the operation switches for both the driver seat and the assistant seat on the center console, the number of operation switches will be large, so that it is easy to give a seated person a complicated appearance.

When the number of operation switches increases due to concentration on the center console, it is impossible to visually confirm and select the operation switches even in the center console, so that the operability is unavoidably deteriorated.

Particularly, in the center console, since the operation switches for the driver seat and the assistant seat are provided adjacent to each other, there is a risk that the operation switches may be erroneously operated, and the comfort and safety of the seated person are sufficiently ensured. Can not.

It is an object of the present invention to provide a power seat switch assembly which reduces the number of parts and improves operability.

[0014]

In order to achieve this object, in the present invention, operation switches having the same structure are
It focuses on being commonly used for driver seats and assistant seats.

Therefore, according to the present invention, at least
The operation switch of the seating posture control device, which is commonly mounted on the driver seat and the assistant seat, which are power seats, is shared, and is installed in the switch unit at a position where any seated person of each seat can operate. . And the adjustment and setting target with the shared operation switch is
It is possible to select either the driver's seat or the assistant's seat under the select switch operation.
