What is a limited-force seat belt?

In case of a head-on collision, it is not only possible to fasten the seat belt in advance to improve the physical binding force on the occupant, but also possible to limit the strength of the seat belt and cushion the impact on the occupant’s chest.

Pretensioner device:

In the case of a head-on collision, the pretensioner will quickly tighten the seat belt, anticipating a strong impact in front, thus increasing the restraint on the occupant’s body.

Load limiting device:

The force limiting device can limit the force acting on the seat belt to a certain extent and reduce the impact on the passenger’s chest.

what is a seat belt pretensioner?

In the process of driving, there is a gap between the safety belt and the human body. The gap is controlled by the winding force of the safety belt, but the excessive winding force will not cause discomfort to the human body. This gap needs to be eliminated in the collision to reduce the forward displacement of the human chest. With the collision signal from the airbag ECU, the high pressure gas from the gunpowder combustion is used as the driving force to tighten the belt, thus producing the pretensioner force.

At present, the structure of pretensioner is mainly divided into steel ball type, steel wire type, rack type and pinion type, its principle is to convert chemical energy into kinetic energy, but there are great differences between the actuators. With compact structure, small size and light weight, the steel ball precompressor can be used with any type of vehicle. Because output is large, the price is relatively cheap, consistency control is good.
