Introduction To Seat Belts

Introduction To Seat Belts

High quality Safety Belt is used in equipment safety parts, flying aircraft, or in the aerial work and technical performance, to ensure the safety of the belt. The main raw materials are polyester, polypropylene and nylon. Seat belt not only refers to the webbing, in addition to the webbing, seat belt and other parts are assembled.

"Seat belt" has become the primary concern for drivers and occupants, and one of the most important properties such as a car. Traditional components to ensure safe driving, such as rearview mirror and left and right door mirror (traditional rearview system), good seat belt, AIRBAG (airbag) and ABS (brake anti-lock system), have been familiar to the majority of drivers and passengers, and are widely used in imported luxury cars.

Type of automobile
1, seat belt prelocking device when the accident occurs, the person forward, the seat back, at this time if the high quality seat belt is too loose, the consequence is likely to be: the passenger slides out from under the seat belt; Or the person has touched the airbag, and the good seatbelt has not been tightened in time because of the excessive tension margin, that is, it has not eaten part of the momentum as hoped, but has given the full burden to the airbag. Both have the potential to cause serious injury to the occupants. But the problem is, properly installed seat belts. Where does the room for loosening come from? First, because the occupant's clothing itself has a certain thickness, in addition, in the SAFETY BELT device also hidden part of the loose room, this room can not be eliminated, but really encounter an accident, should also be eliminated as far as possible. What to do? So there's this belt pretensioning device which is responsible for providing an instant tensioning of the belt.

2. After the accident, the high quality seat belt has been tightened under the action of the pretightening device. However, we want to reduce the tension of the seat belt immediately after the peak force has passed, so as to reduce the force on the occupant. This special task is accomplished by the seat belt tension limber: on the seat belt device, there is a pretightening device as described before, and the seat belt is wound underneath. Inside the core is a steel torsion bar. When the load reaches the predetermined condition, the torsion bar begins to twist, thus relaxing the belt to a certain extent and realizing the tension limit function of the belt.
Under the joint action of the seatbelt pretightening device and the seatbelt tension limitor, the protective ability of the seatbelt almost reaches the ideal state. The so-called subtle spirit, advanced seat belts can indeed provide dependable safety protection for passengers.
3. When the car encounters emergency braking in an accident, it can bind the driver and passengers to the seat, so as not to rush forward, so as to protect the driver and passengers from secondary impact caused by injury.
