Pre-tensioner Mechanism:
  • In collision events, the pre-tensioner ignites gas in a chamber, driving a piston to retract the belt within milliseconds, forcing occupants into optimal crash positions to reduce injury risks
  • Functions alongside conventional locking mechanisms to prevent belt extension during sudden deceleration
Durability & Comfort:
  • Polyester webbing withstands tensile strengths exceeding 23 kN, ensuring resilience under stress
  • Smooth retraction and adjustable fit enhance comfort for daily use

We often encounter such problems in our daily life:

What should I do if the seat belt gets stuck and can't be pulled out?

  1. Adjust the height of the regulator to allow the seat belt to retract further, thereby restoring its elasticity;
  2. Avoid the seat belt and slowly stretch it back and forth at the entrance, stretch it smoothly before slowly pulling out the seat belt;
  3. It is very likely that there is a mechanical failure between the seat belt and the bridge inside the vehicle, and it needs to be disassembled, inspected and repaired at a 4S store;
  4. Seat belts are often not pullable because they are pulled too quickly when using them.

What is the principle of the seat belt locking mechanism?

Seat belt locking is a common car malfunction. Its principle is that the retractor is connected to the seat belt through an internal reel and provides reverse rotation torque to the reel through an internal spring. There are many reasons for seat belt locking, such as damaged seat belt buckle, malfunction of the seat belt retractor, and malfunction of the seat belt tensioner, etc.

Seat belt locking will prevent the seat belt from retracting normally, seriously affecting driving safety. If this situation occurs, please replace the seat belt in time.
