Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a position display device for an automobile seat.

(Prior art) Currently, as women's social status has improved and their leisure time has increased, opportunities for women to drive cars have increased. , there are more and more opportunities for couples to take turns driving the car.

Therefore, when the driver changes from a man to a woman or from a woman to a man, the seat position of the men and women is different due to the difference in the physique of men and women.
They moved the driver's seat back and forth to find their best position.

However, this type of seat operation requires very careful adjustment, and the seat position often needs to be adjusted again after the car has been driven.
It was troublesome and dangerous.

In order to perform the above-mentioned seat operations smoothly, we devised the lock position display device for automobile seat slide rails described in Japanese Patent Application No. 184338/1982 and the Nissan Service Bulletin No.
This is the drive position memory system described on pages 339 to 344 of No. 484 (published June 1984).

First of all, the lock position display device for automobile seat slide rails is a scale with a target mark indicating plate attached to the cushion finisher attached to the side of the seat cushion and a scale displayed on the lower rail fixed to the vehicle body. A scale plate was provided, and a memory indicating plate was provided on the scale plate so as to be slidable back and forth, and facing the target mark indicating plate.

Therefore, if the memory indication board is placed at the position of the target mark indication board in each person's best position, even after the driver takes over and changes the seat position, the memory indicating each person's best position will be retained. By moving the seat so that the target mark indicator board faces the indicator board, the seat can be returned to the best position for each person.

Next, the drive position memory system was an electric seat equipped with a power lifter and power slide operated by computer control.

Therefore, each person's best position can be stored in the computer, and even after another person changes to a different seat position, the seat can be automatically returned to each person's best position with the touch of a button. .

(Problems to be Solved by the Invention) However, such conventional automobile seat position display devices have the following problems.

First, in the case of the lock position display device for a car seat slide rail disclosed in Japanese Patent Application No. 58-184338, since the device was designed to display an indicator located below between the door and the seat, it was difficult to close the door. In this case, when I tried to look at the instruction board, my head hit the door, making it difficult to see.Moreover, in a car with an armrest on the door, it was impossible to see at all.

Further, even if the display device is provided on the inside of the vehicle seat, it is still hardly visible and difficult to use in cars with a center console.

Next, drive position memory systems require computer control and drive equipment, making them very expensive products.

(Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the present invention provides a lower rail provided on the vehicle body side and an upper rail provided at the bottom of the seat that slides with respect to the lower rail. a parallel bracket provided on one of the lower rail and the upper rail in parallel with the other rail at a predetermined interval; a sounding claw provided on either the parallel bracket and the other rail; and a sounding spring provided with a overlap distance with the sounding claw, and the sounding claw or the sounding spring provided on the parallel bracket is provided so that the mounting position can be changed.

(Function) Therefore, in the car seat position display device of the present invention, when you first decide on your best position, if you set it so that the sounding claw and the sounding spring are in opposing positions, the seat When you sit down again after the seat has been changed, slide the seat and when the seat is slid to your best position, the sound claw will flick the sound spring and make a sound, allowing you to know your best position. I can do it.
