<p>PROBLEM TO BE SOLVED: To provide a seat device for a vehicle capable of simplifying configuration of a walk-in mechanism and a fall down mechanism.SOLUTION: A first piece part 22 of a rotational member 20 abuts with a stopper 31 at an abutment edge 22a, to maintain a forward bending posture of a seat back. Under this condition, a pin 24 of the rotational member 20 presses down a link 35 to a slide regulation releasing position. Thus, the slide regulation by a lock member 53 is released, causing shift to a walk-in state. The stopper 31 is moved according to pulling operation of a strap 42 so that an abutment state between the stopper 31 and the abutment edge 22a of the first piece part 22 is released. The rotational regulation of the rotational member 20 is released. Under this condition, the rotational member 20 is further rotated toward forward bending direction, to release pressing state of the link 35 by the pin 24. The lock member 53 comes into a regulation state, causing shift to a fall down state.</p> |
