Claims

[Scope of utility model registration request]

(1) A rail-type slide mechanism that supports a seat so that it can move freely in the longitudinal direction of the vehicle and a rotation mechanism that supports one seat so that it can rotate within a certain range around the approximate center of the seat cushion are combined, The seatback can be moved and rotated in the longitudinal direction, and the folding position of the seatback is defined by the slidable engagement between the member provided on the seat side and the retaining member provided on the floor side. The present invention is characterized by comprising a locking mechanism that restricts the movement of the seat back and allows the seat back to be tilted forward only when the seat is in a prescribed position of the rail-type slide mechanism, thereby allowing the seat to rotate. Walk-in mechanism for vehicle front seats.

(2) The seat-side member is a seatback folding lever, and the floor-side retaining member 1 is attached to the floor side in the longitudinal direction of the vehicle at a position where it can come into contact with the tip of the seatback folding lever. The seatback lever is long and restrains the seatback retractable lever in its operating direction and the seat rotation direction when in an inoperative state, and when the seat is in the forwardmost position along the single slide mechanism, the seatback A walk-in mechanism for a front seat for a vehicle according to claim 1, characterized in that the anti-rotation baffle forms a locking mechanism for releasing a retractable lever.

(3) The locking mechanism is configured so that the tip of the seatback collapsible lever in a non-operating state is slidably fitted in the seat back and forth direction, and when the seat is not in the frontmost position, the tip of the seatback collapsible lever is fitted. A front seat for a vehicle according to claim 2, characterized in that a groove is formed on a side surface of the rotation stopper baffle so as to restrict the movement direction and the rotation direction of the seat. Walk-in mechanism.

(4) The seatback collapsible lever is interlocked with the seatback reclining angle adjustment mechanism, and the seatback reclining angle adjustment mechanism is rotated upward and downward within the range in which the seatback reclining angle adjustment mechanism can be driven. A walk-in mechanism for a front seat of a vehicle according to claim 3, characterized in that the vehicle front seat walk-in mechanism is adapted to allow the following.
