Problems solved by technology

[0010] (3) Some taxi drivers pull out the seat belt, fix the seat belt webbing with a clip at the upper fixing point, and at the same time cross the webbing virtually from the front of the body to cope with the inspection of the traffic police on wearing seat belts, but it is safe The belt is not in the originally designed pre-tensioned initial state;
[0011] (4) A switch signal is arranged in the cushion of the co-pilot's seat, but if a heavy object is placed on the cushion of the co-pilot's position, the warning light will also light up. Even if there is no one in the position, the airbag explodes
[0012] However, in the above-mentioned first three cases, the seat belts did not provide due passive safety protection in the event of a car collision, resulting in the death or serious injury of the driver, and in the case of the above-mentioned fourth case, the safety airbag would be unnecessary in the event of a car collision. the explosion
