The present invention relates to an operation switch for a power seat in a vehicle, which is used for moving forward/backward, tilting the seat and adjusting the level of the front/back portion of the seat.
Reference document, JP H09-240340 (hereinafter referred to as document 1) discloses an operation switch of a power seat in a vehicle, which is formed as an operation switch box provided with a seat reclining switch, seat switches for sliding the seat forward and backward and switches for adjusting the height of the front and rear portion of the seat. This operation switch box is easy to mount but requires the occupant to separately operate each of the switches arranged on the case. Namely, the occupant has to felt for a necessary one of the respective function switches on the switch box and operates it by his or her finger. This operation switch box is not easy to operate and cause incorrect selection of switches.
Reference document, JP Utility Model H06-29111 (hereinafter referred to as document 2) discloses another power seat operation switch which is featured by improved operability and which comprises a round control grip 71 attached to the side of the power seat as shown in
The above-described power seat switch attached to the side of the power seat in the vehicle allows the occupant to adjust the power seat by moving the control grip in accordance with the movement of the power seat in such a manner that the seat is moved forward and backward by moving the grip forward and backward and the back of the seat is tilted forward and backward by turning the grip to forward and backward. However, the occupant being in the state holding the grip cannot operate the seesaw type switches for adjusting the level of the seat.
Accordingly, an object of the present invention is to provide a power seat operation switch whose body is attached to a side of the seat and provided with an operating grip portion which can be operated by the occupant in forward/backward and upward and downward directions relative to the switch body and turned frontward/backward about the axis of the switch body. The power seat switch incorporates in its body a slide switch for sliding the seat forward or backward while the grip is moved forward or backward, a tilt switch for moving up or down the rear portion of the seat while the grip is moved up or down and a reclining switch for reclining the back of the seat frontward or backward while the grip is turned frontward or backward. The grip also incorporate its front part a switch for moving the front portion of the seat upward or downward while a operation knob of the switch is operated in the up-and-down direction.
The power seat operation switch according to the present invention allows a user to adjust the power seat forward/backward and up/down and reclined to suit the occupant by naturally operating by hand only a grip portion of the operation switch, feeling the high operability of the switch in conformity with movements of the power seat.
A power seat operation switch according to the present invention has a main body mounted on one side of the power seat and a control grip portion attached to the main body. The control grip portion of the power seat operation switch can be operated in directions forward/backward and upward/downward relative and also turned forward/backward relative to the main body attached to the seat.
Referring to
The up-and-down movement of the control grip portion causes the lever 21 to move and switch on and off paired seesaw type switches 25 through contactor 24, changing the direction of rotation of a driving motor for moving the rear portion of the seat.
Similarly, the forward-and-backward rotational movement of the control grip portion causes a lever (not shown) attached thereto to move and switch on and off paired seesaw type switches, changing the direction of rotation of a driving motor for reclining the seat. This conventional switch structure is also incorporated in the main body of the power seat operating switch.
Referring back to
The switches for reclining movement A, the switch for back-portion tilting movement B and the switch 3 for front-portion tilting movement C are designed each to automatically return to its normal neutral position where no operation is made.
In the central part of the grip portion 1, a pair of seesaw type push-button switches 4 is mounted, which has two push buttons 41 and 42 for pushing forward and drawing back a lumber support of the seat respectively.
In
In the power seat operation switch for vehicle according to the present invention, the control grip portion 1 may not necessarily be provided at its center part with a pair of push-button switches 4 for adjusting the lumber support.
As is apparent from the foregoing, the power seat operation switch according to the present invention is devised to allow a user to adjust the power seat forward/backward and up/down and reclined to suit the user by naturally operating by hand only a grip portion of the operation switch, feeling the high operability of the switch in conformity with movements of the power seat.
