SAFETY BELT RETRACTING AND LOCKING APPARATUS AND AUTOMOBILE SEAT

A seat belt retracting and locking apparatus and an automotive seat including a seat belt retractor, a sensor having a sensing seat and a sensing ball, and a locking mechanism. When the locking mechanism is in a locking state, the sensing seat is fixed in an initial position. When the locking mechanism is in an unlocking state, the sensing seat is rotatable. When the seat belt retracting and locking apparatus and the automotive seat are in a normal state, the sensing seat is locked in the initial position by the locking mechanism, and the angle and the position of the sensing seat are not affected by a change in the speed of a vehicle, so that relative positions between the sensing ball, a pawl, and a ratchet do not change, thereby improving the stability of the performance of the apparatus and seat.
