- the operating plate 50 is provided with a presser pin 50b for pressing the regulating lever 53 at the lower end side, and the presser pin 50b is formed on the side frame 2 with a second upwardly sloped frontward slope.
- the operating plate 50 is attached to the side frame 2 so as to be swingable about the support shaft 50a by slidably fitting the arcuate guide hole 21 in the first embodiment.
- the tension applied to the rear side of the side frame 2 so that the presser pin 50b for pressing the control lever 53 is always located at the lower end of the second arcuate guide hole 21.
- the working plate 50 is pulled by the spring 50c.
- the link rod 51 is arranged so as to bridge between the operation plate 50 and the cam plate 52.
- the linking rod 51 has a traction pin 51b on the upper end side, and the lower end side is pivotally connected to the middle abdomen of the operating plate 50 by a support shaft 51a.
- the traction pin 5 1b provided on the upper end side of the link rod 51 is provided with a third guide hole 22 formed in the side frame 2 to extend obliquely upward and forward to control a cam plate 52, which will be described later. It penetrates through the hole 52b and is slidably fitted along the third guide hole 22 and the control hole 52b, so that the link rod 51 is attached to the operating plate 50. And can swing freely.
- the support shaft 5 la of the linkage rod 51 penetrates the operation plate 50 and extends forward to the side frame 2 and is a fourth guide having an upwardly inclined arc shape.
- the cam plate 52 which is slidably fitted in the hole 23, is rotatably supported on the side frame 2 at a substantially middle portion of the plate surface by a support shaft 52a. Near the upper edge of the cam plate 52, a substantially U-shaped notch hole 52c capable of receiving the guide pin 43b of the jumping arm 43 is provided. Further, a control hole 52 b is provided on the plate surface near the lower end of the cam plate 52.
- This control hole 5 2 b It has an arc-shaped hole portion 5 2 b ′ extending in the front-rear direction of the plate surface, and a linear hole portion 5 2 b ′′ extending continuously upward from the front end of the arc-shaped hole portion 5 2 b ′
- the pin end of the traction pin 51 b protruding from the third guide hole 22 of the side frame 2 is slidably fitted in the control hole 52b.
- the regulating lever 53 is directed toward the rear side of the side frame 2, toward the first arm portion 53 a that comes into contact with the holding pin 5 Ob of the operating plate 50, and toward the bottom surface of the lower rail 1 a.
- a substantially inverted L-shape is formed from the second arm portion 53b.
- the control lever 53 is pivotally supported on the upper rail 1b by pivotally connecting a substantially middle portion of the plate surface to a side surface of the upper rail 1b with a support shaft 53c.
- a tension spring 53d is stretched between the second arm 53b of the regulating lever 53 and the rear of the upper rail 1b.
- the stopper plate 54 is attached and arranged in a front area of the lower rail 1a which is deviated from a normal seating position.
- the stopper plate 54 holds the second arm portion 53b of the regulating lever 53 at the lower end, so that the regulating lever 53 cannot swing. This prevents the entire seat from moving from the seated position in a predetermined forward direction.
- the seat cushion C is maintained in the sitting position unless the panel locking mechanism that locks the spiral panel 42 so that the panel can be biased is unlocked by operating the knob. .
- the holding pin 50b of the operating plate 50 comes into contact with the first arm portion 53a of the regulating lever 53, the regulating lever 53 cannot swing, and the The lower arm portion 53b is in a state where it can contact the stopper plate 54 at the lower end side. Therefore, in this state, even if the operation lever for operating the lock piece 3 of the slide lock mechanism is operated to release the locking projection 3a of the lock piece 3 from the locking hole of the lower rail 1a, Since the second arm 5 3 b of 5 3 contacts the stopper plate 54 at the lower end, the stopper plate 54 is attached to the sheet. It is kept immovable forward of the lower rail 1a.
- the holding pin 50b of the operating plate 50 moves forward and upward along the second arcuate guide hole 21 of the side frame 2. . Accordingly, the regulating lever 53 swings clockwise about the support shaft 53c by the action of the tension spring 53d. At the same time, the traction pin 51b of the linkage rod 51 reaches the base position of the linear hole 52b of the control hole 52b, and the traction pin 51b is linearly connected to the control hole 52b. It is possible to move to the hole 52b ".
- the operation plate 50 is in a state capable of swinging counterclockwise. Therefore, even if the second arm portion 5 3b of the control lever 53 contacts the stop plate 54 at the distal end, the control lever 53 can rotate clockwise. In other words, the lock mechanism 5 is unlocked, which allows the seat to move forward from the predetermined seating position.
- the second arm 53b of the regulating lever 53 is positioned at the distal end as shown in FIG.
- the regulating lever 53 is rotated clockwise while hitting the stopper plate 54, whereby the pressing pin 50 of the operating plate 50 abutting on the first arm 53a of the regulating lever 53 is held.
- b is pushed above the second guide hole 21 of the side frame 2, and the traction pin 51b of the linking rod 51 is connected to the linear hole 52b of the control hole 52b.
- the restricting lever 53 comes up on the plate of the stopper plate 54. This allows the occupant to position the entire seat forward while holding the hand on the operating lever of the slide lock mechanism. You will be able to move it.
- the entire seat is moved rearward while the seat cushion C is in the upright posture, and the regulating lever is moved as described with reference to FIG.
- the guide pin 50b becomes movable along the second guide hole 21 and the cam plate 52 becomes rotatable.
- the user can return the seat cushion C to the seating posture by turning the seat cushion C downward by hand after unlocking the tip-attack mechanism 4 by operating the operation knob. .
- the regulating lever cannot swing due to the pressing of the operating plate by the holding pin.
- the guide pin of the jumping arm rotates the cam plate, and the cam plate pulls the link rod to hold the seat cushion. Since the rod swings the operating plate, the operating plate releases the pressing of the control lever by the presser pin, and the control lever can ride on the stop plate. In this state, the entire seat can be moved to a predetermined position, so that it can be configured with a simple structure as an interlock mechanism that interlocks with the lifting of the seat cushion by the tip-up mechanism.
