Abstract:
1. A seat device for a vehicle comprising: a reclining mechanism housed in an inner space formed between a fixed member and a movable member, the fixed member being adapted to be mounted on a seat cushion and the movable member being adapted to be mounted on a seat back, the reclining mechanism supporting the movable member rotatably relative to the fixed member and having a locked state in which the movable member is held at an angle position relative to the fixed member by limiting a rotation of the movable member relative to the fixed member within a predetermined regular angle range and an unlocked state in which the movable member is allowed to be rotated relative to the fixed member; an operation lever connected to the reclining mechanism to be moved from an initial position thereof to an operating position thereof for changing a state of the reclining mechanism from the locked state to the unlocked state; a base member attached at either one of the fixed member or the movable member; a latch member attached at the other one of the fixed member or the movable member; a memory member being engageable with the latch member and rotatably supported by the base member so as to be rotated relative to the base member integrally with the latch member when the memory member is engaged with the latch member; an actuating member coupled to the movable member so as to be rotated in conjunction with the rotation of the movable member relative to the fixed member at the outside of the regular angle range, an engaging member coupled to the actuating member, held at a disengaged position relative to the operation lever when the movable member is within the regular angle range and moved to an engaging position relative to the operation lever when the movable member is outside of the regular angle range so as to prevent the operation lever from returning from the initial position to the operating position; the reclining mechanism including: a swing lever supported by the base member, connected to the operation lever, and connected to the memory member for transmitting the movement of the operation lever from the initial position to the operating position so as to engage the memory member with the latch member; and the operation lever including a shaft at which the cam is fixed and a first pin engaged with the swing lever, the operation lever being moved from the initial position to the operating position so as to rotate the cam for disengaging the outer peripheral gear of the pawl from the inner peripheral gear and rotate the swing lever for engaging the memory member with the latch member.
