Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation switch for a power seat for a vehicle in which the position and orientation of an occupant can be adjusted.

[0002]

2. Description of the Related Art Conventionally, a vehicle seat is provided with an adjusting mechanism which can adjust a front-rear position, a height, and a body pressure distribution of a seat so that an occupant can easily drive and the like. There is a configuration in which this adjustment mechanism is operated by using a drive source such as a motor (Japanese Patent Laid-Open No. 61-2).
No. 38541). In this structure, an operation switch as an operation member for controlling the drive source is provided on an outer surface of a seat or the like, and an occupant operates the operation member of the operation switch to perform adjustment. Further, in this structure, the state adjusted to the optimum state is registered in a storage unit provided in the operation switch, and can be reproduced by calling up the stored information.

[0003]

However, in the above-described conventional power seat for a vehicle, when the operating member of the operating switch is continuously pressed, the adjusting operation is performed in a stepless manner, and when the operating member is released, the operating member is operated. Since the member returns to the original neutral position, looking at the surrounding structure of the operation switch,
It was not possible to visually confirm how much adjustment was being made at present, and had to judge the current state by experience. Also, although the user can register in the storage unit and reproduce it later, how much should the user press the operating member in the neutral position when changing the current state or making fine adjustments? Some have pointed out that it is difficult to judge. Note that the method of registration in the storage unit is complicated in structure and operation, and the number of operation members is increased, resulting in poor usability. Furthermore, conventional operation members are simply arranged on the switch panel, and are given names such as reclining and slide, and the user can visually check the operation member names and select the operation members. When it is desired to perform an adjustment operation during driving, the target operation member must be searched by groping, and such consideration has been lacking.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object the purpose of visually confirming the adjusted current state, making fine adjustments from that position, and moving the operating member when adjusting. It is an object of the present invention to provide an operation switch for a power seat for a vehicle, which makes it possible to predict the power consumption of the vehicle and to improve the usability. Another object of the present invention is to achieve a simpler configuration and to easily determine a target operation member even in a non-visual state. Still other objects will be sequentially clarified in the contents described below.

Here, the first switch section 4A is configured as follows. The operating member 13 has a substantially Japanese character shape, is located in the concave portion 6, and is disposed so as to be movable in the front-rear direction. On the lower side of the operation member 13, a rack bar 14 penetrating through a slit 61 formed on the lower surface of the recess 6 is provided.
The rack teeth formed on the rack bar 14 are meshed with a gear 15 driven by the motor 12. When the operating member 13 horizontally moves the operating member 13 in a direction in which the seat cushion 2 is to be moved, a pressure-sensitive switch (not shown) detects the moving direction, and the motor 12 operates in the detected moving direction and Driven in proportion to the amount of movement, the seat slide mechanism 10 moves the seat cushion 2 (or the entire power seat 1) forward or backward by a predetermined amount. The operation panel 5 is provided with a plurality of scales 16 at equal intervals along a portion where the operation member 13 moves. This scale 16
Corresponds to the adjustment of the seat cushion portion 2 (or the entire power seat 1) or the front and rear position to be adjusted. After the adjustment, the scale 16 corresponding to the pointer 17 of the operation member 13 is visually checked, and thereby the seat cushion portion is adjusted. 2 can be recognized through the scale 16 in the front-rear direction. Therefore, for example, if the user remembers this position after the adjustment and moves the operation member 13 at that position at a later date, the position of the seat cushion 2 is reproduced.

The operating member 23 and the operating member 33 are divided into left and right openings 18a and 18b formed in the operating member 13 and are disposed so as to be movable up and down.
Operation members 23, 33 are provided on the periphery of the openings 18a, 18b.

On the other hand, the second switch section 4B is configured as follows. The operation member 43 is formed in a substantially cap-like or annular shape, and is rotatably disposed in the recess 7. A plurality of graduations 49 are formed at equal intervals on the periphery of the concave portion 7 at a portion where the operation member 43 rotates. When the operation member 43 is rotated or moved forward or backward to adjust the angle of the seat back portion 3, a pressure-sensitive switch (not shown) detects the rotation direction and the motor 42 detects the rotation direction. The reclining mechanism 40 tilts the seatback unit 3 forward or backward by an amount corresponding to the amount of rotational movement of the operation member 43. Also in this case, the scale 49 corresponds to the angle adjustment of the seat cushion 2 or the angle position to be adjusted. After the adjustment, the scale 49 corresponding to the pointer 43a of the operation member 43 is visually checked. The angle or the inclined position of the seat cushion portion 2 can be recognized through its scale 49. Therefore, for example, after the adjustment, the position is memorized, and the rotational movement is performed so that the operating member 43 is arranged at the position at a later date. Then, the angle or the inclined position of the seat cushion 2 is reproduced.

The operating member 53 has an arc-shaped slit 54 provided in a part of the recess 48 (the slit 54 corresponds to the moving range of the operating member 43).
It is arranged movably along. In the recess 48, a plurality of scales 59 are formed along the slit 54 at equal intervals. When the operation member 53 is moved along the slit 54 in accordance with the direction in which the protrusion of the lumbar portion of the seat back portion 3 is increased or decreased, a pressure-sensitive switch (not shown) is moved. When the direction is detected, the motor 52 is driven in the detected direction and in proportion to the amount of movement, and the lumbar support mechanism 50 projects or projects the lumbar portion of the seat back 3 by an amount corresponding to the amount of movement of the operation member 53. Adjust. Also in this case, the scale 59 corresponds to the lumbar adjustment or the amount of protrusion to be adjusted in the seat back portion 3. After the adjustment, the scale 59 corresponding to the pointer 61 of the operation member 53 is visually checked. The adjustment state of the lumbar portion can be recognized through the scale 59. Therefore, for example, if the user remembers this position after adjustment and moves the operation member 53 to the position at a later date, the lumbar portion is moved. The state of the part will be reproduced.

In the present invention, the operation switch 4 described above is used.
