Why Can't the Seat Belt in My New Car Be Pulled Out?
1 Answers
If the seat belt in a new car cannot be pulled out or the length is insufficient, it is likely because the pulling speed is too fast. You should pull the belt slowly. The Function of Car Seat Belts: Car seat belts, also known as safety belts, are a type of occupant restraint system. They are designed to restrain occupants during a collision, preventing secondary impacts with the steering wheel, dashboard, or other parts of the vehicle, and to avoid injuries or fatalities caused by being ejected from the vehicle. Working Principle: The seat belt system connects the belt to a retractor, which stores the webbing and locks it when pulled. The retractor is the most complex mechanical component in the seat belt system. Inside the retractor is a ratchet mechanism. Under normal conditions, occupants can pull the webbing freely and at a steady speed. However, if the webbing is abruptly stopped during extraction or if the vehicle encounters an emergency, the ratchet mechanism will engage, automatically locking the webbing to prevent further extraction. The mounting hardware, such as brackets, clips, and bolts, connects the seat belt to the vehicle body or seat structure. The installation position and stability of these components directly affect the protective effectiveness of the seat belt and the comfort of the occupants.
