Claims

[Scope of utility model registration request]

An upright position is connected to a rear position in the longitudinal direction of the seat cushion extending in the vehicle width direction so as to be able to be raised and lowered in the longitudinal direction of the vehicle by a hinge mechanism, and stands substantially perpendicular to the seat cushion. A first seat back that can be set in three positions: a forward-folded position in which the seats are laid down in a substantially overlapping state on the seat cushion, and a reclined position that is tilted further rearward than the above-mentioned upright position; A rear seat for a vehicle is provided with a second seat back that can be positioned in two positions and arranged in a row in close proximity to each other in the vehicle width direction, wherein the axis of the hinge mechanism of the first seat back and the second seat back are located close to each other in the vehicle width direction. The axis of each hinge mechanism is appropriately offset in the direction of its rotating surface, and the hinge mechanism is located between the first seat back and the second seat back in the vicinity of each of the hinge mechanisms, and the hinge mechanisms are offset from each other. When the first seat bag is set to the reclining position and the second seat bag is set to the forward folding position, the second seat bag is moved forward by utilizing the difference in the rotation locus of the first seat bag and the second seat bag based on It restricts rotation from the reclined position to the upright position, and also controls the rotation of the first seat back and second seat.
When both seat backs are set to the upright position, the rotation of the first seat back from the upright position to the reclined position is restricted, while when the second seat back is set from the upright position to the forward folded position, the rotation of the first seat back is restricted. A lower rotation restriction mechanism for canceling the rotation restriction function is provided, and further between the upper part of the first seat bag located on the inside in the vehicle width direction and the upper part of the second seat bag located on the inside in the vehicle width direction. By utilizing the difference in the rotation locus of the first seat bag and the second seat bag based on the offset between the hinge mechanisms, the first seat bag can be moved to the second seat bag when the first seat bag and the second seat bag are both in the upright position. When the first seat bag and the second seat bag are both in the forward folded position, these joints are released and the seats are moved from the forward folded position to the upright position. A rear seat structure for a vehicle, characterized by being provided with an upper rotation restriction mechanism that allows rotation of the vehicle.
