Abstract
The system consists of a ring gear setup which lies below the seat. The seat belt is mounted on the ring gear which is meshed with a pinion driven by a motor. Provisions are made to adjust the ring gear setup based on the position of the buckle which can be altered according to the convenience of the passenger. The ring gear is designed to follow maximum possible projectile to accommodate passengers of different size. Once the passenger occupies the seat, the motor is switched on in the forward direction. The belt is carried by the curved ring gear and locked with the buckle. Once the seat belt is locked with the buckle, the motor runs in the backward direction till the ring gear is brought back to its initial position. In the existing scenario of automatic seat belts, belts are attached to doors. A crash that causes the doors to open leaves the passenger unprotected. The foremost advantage of this type of automatic seat belt is that it is attached to a sturdier portion i.e. frame of the car instead of doors.
