[0002] After the seat belt of a private car is fastened, because the seat belt passes through the waist and the hole of the buckle is movable and not locked, when the vehicle collides, the occupant will instantly dive forward under the action of huge inertia, and lag behind slightly. The seat belt only works, because the locking device of the seat belt has a certain lag time, so under the action of inertia, the occupant's buttocks will lift up and leave the seat for a certain distance before being pulled by the seat belt. However, due to the lag time of this small meeting, the human body has already left the seat for a certain distance, which reduces the collision distance. In this way, the body and the head often have Hit the steering wheel and the front windshield, ranging from injury to life-threatening
