Abstract:
1. A seat apparatus for a vehicle, comprising: a first lock mechanism switching between a first locked state, in which a seatback being pivotable between a first position and a second position of the seatback relative to a vehicle floor is retained at a predetermined reclined position relative to the vehicle floor, and a first lock-released state, in which the seatback is allowed to pivotally move between the first position and the second position thereof relative to the vehicle floor; a second lock mechanism switching between a second locked state, in which a seat cushion being movable between a first position and a second position of the seat cushion relative to the vehicle floor is retained at a predetermined position relative to the vehicle floor, and a second lock-released state, in which the seat cushion is allowed to move between the first position and the second position thereof relative to the vehicle floor; and a guide wall member adapted to be secured to a vehicle floor side and including a guide hole fitted with a guiding protrusion protruding from the seat cushion, the guide wall member defining a path for the guiding protrusion moving between a first position and a second position of the guiding protrusion, wherein the first lock mechanism includes a restraining member restraining a pivotal movement of the seatback at a predetermined angle position, at which the seatback does not interfere with the seat cushion moving between the first position and the second position thereof, when the second lock mechanism is in the second lock-released state, the first lock mechanism further includes a releasing member linked to the restraining member and releasing a restriction to the pivotal movement of the seatback by being moved in association with a movement of the seat cushion when the second lock mechanism is in the second lock-released state, the releasing member includes an elongated shape extending in parallel with the guide hole of the guide wall member, a connecting portion provided at a first end thereof and pivotably connecting the restraining member relative to the releasing member, a contacting portion provided at a second end thereof so as to be movable along a path for the guiding protrusion of the seat cushion and positioned between the guiding protrusion of the seat cushion and the second position of the guiding protrusion so as to be pressed to move by the guiding protrusion, and a support shaft provided between the connecting portion and the contacting portion and supported by an elongated hole member, and wherein the elongated hole member is secured to the guide wall member and includes an elongated hole extending in a guiding direction of the guide hole of the guide wall member and fitted with the support shaft of the releasing member so as to allow the support shaft to slide in a longitudinal direction of the elongated hole.
