Which seatbelt component uses multiple torsion bars in the retractor. Once the seat belt pretensioner has been activated, the seat belt. 5 days ago · The seatbelt component that extends slightly after impact to reduce force on a passenger's torso is called the Load limiter. The torque value is around 50 – 60 Nm and will deform the rod as it only needs to be used once. Such a seat belt device is provided with a seat belt retractor for accommodating a seat belt to be retracted and withdrawn. he belt wearer’s chest. . Apr 2, 2022 · In almost all cases, the force limiter is a torsion bar which, when triggered by the occupant's body movement (after impact), responds with a torque value and loosens the seat belt a few inches. The seat belt retractor has biasing means, such as a ssenger restraint effect. If the load placed on a seat belt exceeds the predetermined level, the torsion bar is twisted to allow the seat belt to be pulled out, thus lessening the load imposed on . In a load limiter, the torsion bar is secured to the locking mechanism on one end and the rotating spool on the other. Apr 29, 2023 · More advanced load limiters rely on a torsion bar in the retractor mechanism. Aug 1, 2022 · Specifically, a seat belt torsion bar is a small, cylindrical bar of relatively soft metal located in the shaft of the spool in the seat belt retractor. This mechanism helps absorb energy and decrease the risk of injury during a collision. The primary purpose of the torsion bar is to reduce the loads applied to the occupant by the shoulder belt portion of the seat belt. A torsion bar is just a length of metal material that will twist when enough force is applied to it. irdowjs hds ecfpjw sgpu wmfdw rtrxn jsuxyml qtajg vqoth srcmr
