Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control switch for an automobile power seat having a memory function and a limit switch and operation switch function.

[Prior Art and Problems to be Solved by the Invention] Conventionally, when getting on and off of light passenger cars, the seat is moved rearward or the backrest is rotated to make getting on and off easier. This is done electrically, but manually there are two operations (moving the seat,
(the backrest tilts), and electric models have the inconvenience of having to keep pressing a switch, so in many cases they are not actually used.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was invented to eliminate this problem, namely, by attaching a case to the seat side where the guide slot is provided and moving the toggle switch. attached to the member side, so that the operating knob from the toggle switch protrudes to the outside of the case through the guide elongated hole,
When getting in or out of a car, the system automatically stops when the seat is moved to the rear end, and then automatically stops when the toggle switch operating knob is moved to a preset position with a single touch. To provide a control switch that can be quickly returned to a set position and eliminates the trouble of frequently moving the ingress/egress switch or the seat side.

[Embodiment] Next, an embodiment of a control switch for an automobile power seat according to the present invention will be described with reference to the drawings.

1 is the switch case body, which is attached to the seat 2 side. The top surface of this case body 1 is the seat 2
An operating knob 7 of a toggle switch 6, which will be described later, is located inside the case body 1 on an arcuate surface 5 having a radius centered on a rotary shaft 4 which is horizontally supported and connected to the seat bases 3 disposed on the left and right sides. A guide slot 8 is provided in the longitudinal direction for guiding the operation knob 7, and the operation knob 7 is projected upward through the guide slot 8.

Further, inside the case body 1, the toggle switch 6 attached to the distal end side of the detection bar 9 whose base end is attached to the rotating shaft 4 is located, and the guide elongated hole 8
A position memory plate 10 that moves along the inner wall and is fixed at an adjusted position is provided on the inner wall.
The position memory plate 10 is fixed by moving it along an arcuate guide hole 12 on a radius around the rotating shaft 4 provided on the front plate 11 of the case body 1 and fixing it by appropriate means. Control switch A is configured in this way.

Next, an example of the use of this control switch A will be explained with reference to FIGS. 2 and 3.

The seat base 3 is provided with a bracket 17 on one end (rear end) side, and this bracket 17 is connected to one end (rear end) of a movable rail 16 fitted to a fixed rail 15 fixed to the floor side of the automobile so as to be slidable back and forth. The rotating shaft 4 is connected to the bracket 16a provided in the seat base 3 by a pin 18, and the rotating shaft 4 is connected to the other end (front end) side of the seat base 3 by a horizontal bearing between the seat bases 3. The seat base 3 is supported by fixing the end portions of the support member 20, which is bent so as to be pivotally supported by a bearing member 19 whose center portion is attached to the floor side, by welding or the like. Accordingly, the seat base 3 swings around the pin 18 of the bracket portion by the rotation of the support member 20, and at the same time moves the movable rail 16 along the fixed rail 15. The support member 20 includes
A sector gear 21 is attached, and the reduction mechanism 22 meshes with a pinion 23 from a reduction mechanism 22 attached to a connection plate 13 which is installed between the seat bases 3 and 3 and connected. The rotation of the motor 14 connected to the motor 6 is decelerated, and this is transmitted to the pinion 23. Further, the shaft of the pinion 23 is supported at one end by the support arm 24, which is supported at one end by the rotating shaft 4, and the shaft of the pinion 23 is always
is arranged to mesh with the sector gear 21.

[Function] As is clear from the above configuration, the present invention allows the operating knob 7 to be moved from the toggle switch 6 that protrudes through the guide slot 8 of the case body 1 when getting on or off the vehicle.
When it is tilted in the No. 1 direction, the motor 14 is driven and the support member 20 is rotated about the bearing member 19 via the deceleration mechanism 22, and the rotating shaft 4 with the end of the support member 20 fixed to one end rotates. Cooperation and detection bar 9
moves with the toggle switch 6. In this case, the rotation of the support member 20 causes the seat base 3 to swing around the pin 18 of the bracket provided on the movable rail 16, and the seat base 3 further uses the support member 20 to move the movable rail 16 along the fixed rail 15. Move forward. Further, the operation knob from the toggle switch 6 at the tip of the detection bar 9, which is interlocked with the rotation of the support member 20, moves and hits the position memory plate 10 set in advance on the case body 1, so that the operation knob 7 is switched.
It turns OFF and stops driving the motor. Furthermore, when the operation knob 7 is tilted in the No. 2 direction, the opposite operation of the above operation is performed, the operation knob 7 moves, and the case body 1
The operating knob 7 hits the inner edge of the end of the long guide hole 8, and the switching operation stops and returns to the initial position.

Therefore, by arbitrarily setting the position of the position memory plate 10, the movement range can be freely adjusted.

[Effects] As described above, the present invention includes a case that is provided with a guide slot and is mounted on the seat side, and a case that is located inside the case and protrudes outward from the guide slot. A control switch for a power seat for an automobile, characterized in that a toggle switch equipped with a guided operation knob is attached to the tip of a position detection bar, and the toggle switch 1
It is economical to have the functions of a limit switch and an operation switch by itself, and also to have a memory function by using a position memory plate. In addition, since the case and toggle switch move relative to each other as the seat moves, it is possible to monitor the position of the seat throughout its entire stroke, and it is also possible to move from the set position to the rear end with a single touch operation. No hassle. Furthermore, the seat position can be confirmed at a glance.
