Claims

[Scope of utility model registration request]

This locking mechanism is disposed at the lower rear side of the cushion in a foldable seat that can stand up on a floor panel by pivoting forward using the front end of the seat cushion as a fulcrum, and is used to maintain the seat in a seated position. A lock base for supporting a lock plate that can be engaged with and detached from a lock pin provided on the floor panel is placed in a state protruding from the lower part of the seat cushion, and the upper side of the lock base is placed against the cushion frame. a front end of a link extending in the front-rear direction on the lower surface of the seat cushion is rotatably attached to the floor panel at a lower portion slightly rearward from the center of rotation of the seat cushion;
A locking mechanism for a folding seat for a vehicle, wherein the rear end of the link is rotatably connected to the lock base, and the lock base is rotatably displaced inside the seat cushion when the seat is raised.
