What do you mean by automatic seat belt tightening system?
The pretensioner mechanism uses an explosive charge to drive a concealed piston when sensors detect the signature abrupt deceleration of an accident. The piston, in turn, rapidly drives the spool around which the fabric strap of a seatbelt is wrapped.
How to Stop Your Seatbelt from being too tight?
Move your seat back to free up some extra room. Lower the seat if you are tall or raise it if you are short: seatbelts are designed for individuals of average height. Get comfortable before you buckle your seatbelt. If you sit back while buckling, but want to inch forward during the ride, it’s going to seem too tight.
Can a seatbelt be repaired after it has been activated?
Regardless of whether it’s the seatbelt retractor, or the buckle pre-tensioner, once activated, they will not work again. All seatbelt parts must be inspected before the repair is started.
What happens when you release the webbing on a seatbelt?
If you release the webbing, the spring will tighten up, rotating the spool clockwise until there is no more slack in the belt. The retractor has a locking mechanism that stops the spool from rotating when the car is involved in a collision. There are two sorts of locking systems in common use today:
How does the front seat seat belt work?
The front seats are a bit different, as they come with pretensioners. Working with the SRS airbag system, the pretensioners will wind up any slack in the seat belt webbing during a collision. This will hold the occupant away from hitting the dashboard and prevent injury.

How are seatbelts used in a car accident?
In the unfortunate event of a collision, seatbelts help protect the occupants from injury. During a collision, the airbag computer initiates the seatbelt igniter to ignite, activating the seatbelts and locking them into position around each occupant wearing the seatbelt.
Where does the webbing in a seatbelt come from?
A seatbelt consists of a belt made of flexible webbing and a retractor device. The retractor, usually located inside a plastic housing above the passenger’s outer shoulder, consists of a spool around which the belt winds, and a spring attached to the spool to keep the webbing taut.
