When moving along the second step 184 ′, the third step 186 ′, and the fourth step 188 ′, it can respond actively, and at the same time, it can be moved freely left and right by the guide means 500. The direction of the pin 520 can be easily changed.

  Hereinafter, an operation process of the above-described embodiment of the present invention will be described.

  In the present invention, after the seat belt b is inserted and fixed between the detachable cover 200 and the main body 100, the hook 190 can be applied to an appropriate position inside the vehicle.

  When the seat belt b is pulled as much as necessary to loosen the seat belt b that presses the occupant, the seat belt b does not recover due to the pulling force of the embryo that is installed in the retractor of the car. The process of maintaining will be described.

  When the seat belt b is fixed by the upper unevenness 220 and the lower unevenness 360, when the seat belt b is pulled slightly, the pinion 340 rotates about the rack 164 and the stopper 300 advances, and the guide pin 520 moves along the first groove 182. move on.

  After the guide pin 520 travels to the maximum, it descends through the first step 182 ′ and reaches the second groove 184, and then moves backward a little and then descends at the second step 184 ′. Stopped at the point where the third groove 186 meets, stops moving further, and stops in the stopped state.

  In this state, the occupant can easily adjust the tightening length (relaxation degree) of the seat belt b.

  After adjusting the length appropriately, if the seat belt b is pulled again a little and then released, the guide pin 520 advances a little along the third groove 186 and descends to reach the third step 186 ′ to the fourth groove 188. Then, after moving backward along the fourth groove 188, it descends again at the fourth step 188 ′ and completely moves backward in the first groove 182.

  Then, the seat belt b is in the initial position of the upper unevenness 220 and the lower unevenness 360, that is, in a state of facing each other.

  Eventually, since the seat belt b is in a state of being restored by the retractor, when the seat belt b is restored a little while the tightening length is adjusted, the space between the upper unevenness 220 and the lower unevenness 360 is reduced. The seat belt b is hung on and stopped without being restored by the mutual friction force.

  For reference, the guide pin 520 advances only in one direction due to the first step, the second step, the third step, and the fourth step, and does not move in the opposite direction.

Through such a process, the occupant can maintain the loosened state by adjusting the tightening state of the seat belt b by performing the operation of pulling the seat belt b little by little twice.
