• When the seat belt lock release function is not operated, the weight is under a no-load condition. When a sudden shock is applied to the vehicle, the weight moves to push the actuator upward. The actuator engages with a lock gear and stops its rotation (ELR condition). Due to this, the rotation direction of belt pull out is stopped.
• When a front seat belt is not in use, the lock release solenoid turns on, pulling the cancel lever upward, if a door is opened (during the seat belt lock release function operation). As a result, the actuator and weight are fixed in their positions. Due to this, the front seat belt pulls out smoothly.
