[Prior Art 1] A front seat of a passenger car is provided with a mechanism for adjusting the position forward and backward. For example, Utsukai 58-1292
There is a 4T structure as shown in Publication No. 35, but generally a slide rail is laid on the floor and a support member for the seat is placed on this to perform longitudinal adjustment. However, with slide rails, the seat simply moves back and forth (), so it is not possible to change the forward inclination angle of the seat, and the space under the seat is blocked, making it difficult for rear seat occupants to move the seat back and forth. The problem was that I couldn't stretch my legs and lie down.

Therefore, in order to adjust the seat back and forth, if the occupant grasps the operating handle 27 and pulls it in the [ ] direction (shown in Figure 2), the lever 20 will move against the bias of the spring 23. It rotates in the Q direction (-> as shown in Fig. 2) about the pin 19,
The lock bin 22 is removed from the lock groove 25 and becomes free to handle. In this state, if the three-point supported seat cushion 2 is moved to the desired front-rear position and the operating handle 27 is released, the lever 20 will be rotated in the opposite direction under the bias of the spring 23, and the lock pin will rotate in the opposite direction. 22 is locked in the nearest lock groove 25. The seat cushion 2 is then fixed at a desired position.

[Effects of the Invention] As described above, the seat cushion is supported by the links and stays and is supported at three points. The states of the cushion frame, links, and stays that occur when the front and rear positions of the seat change are as shown in FIG. 5, and the forward inclination angle of the seat cushion changes.

That is, when adjusting the position of the seat rearward, the front part of the cushion is lowered, and the contact between the crotch of the rider and the cushion during pedal operation is alleviated. The front and rear adjustment range or forward tilt angle depends on the link and stay installation positions.
;By selecting the length, there is an advantage that it can be freely matched to the vehicle's appearance.

Also, since there is no slide rail and it is supported by links and stays, the structure is extremely simple.
A large space is formed below the seat cushion. Therefore, the occupants in the rear seats can stretch out their legs 28 (shown in FIG. 1) in this space and relax, which has the advantage of greatly improving the comfort of the occupants.
