Claims

[Scope of utility model registration request]

A lock bracket is attached to the rear of the seat cushion so as to be rotatable in the vertical direction and protrudes downward, and a striker is attached to the lock bracket so as to be rotatable in the vertical direction and protrudes from the vehicle floor. a ratchet that is attached to the lock bracket so as to be rotatable in the vertical direction and elastically engages with the hook to restrict the rotation of the hook; an operating wire that rotates the ratchet in a direction to release the engagement with the hook when operated; a support bracket that is fixed to the vehicle body floor and is assembled to enable the front portion of the seat cushion to rotate in the vertical direction; The seat cushion is rotatably assembled to the lock bracket, and when the seat cushion is rotated upward about the support point of the support bracket, the lock bracket is rotated and the seat cushion is rotated relative to the seat cushion. In a locking mechanism for a vehicle seat comprising a link that rotates in a non-protruding direction, the tip of the outer tube constituting the operating wire is fixed to the seat cushion side at a predetermined distance from the lock bracket. . A locking mechanism for a vehicle seat, characterized in that a distal end portion of an inner cable forming the operation wire and passing through the outer tube is connected to the ratchet.
