Claims

[Scope of utility model registration request]

Side parts protruding forward or upward are provided on both sides of the seat back or seat cushion, and the side part on the vehicle door side of both side parts is configured to be able to expand outward and return to the return position using a lock mechanism. In a vehicle seat in which a door is locked and an unlocking operation of the locking mechanism is linked to an opening operation of the door, a switch that detects the opening operation of the vehicle door is connected to the locking mechanism via a push-pull cable. and an electromagnetic actuator whose operation is controlled by the switch to unlock the lock mechanism.
