ZF unveils sensible seat belt know-how



The progressive method of this know-how lies not solely within the particular person management choices of the element itself, but additionally within the prolonged prospects for interplay with different security programs.

With its new seat belt system, ZF Passive Security Methods will allow considerably improved adaptation of the belt drive limitation to the scale and physique weight of the car occupants sooner or later.

The Multi-Stage Load Limiter (MSLL) is primarily liable for the person system adjustment. It helps to additional scale back the implications of accidents for all occupants and permits automobile producers to fulfill the elevated necessities of the NCAP Roadmap 2030, the corporate stated in a media launch.

The progressive method of this know-how lies not solely within the particular person management choices of the element itself, but additionally within the prolonged prospects for interplay with different security programs. This turns the seat belt with the MSLL switchable drive limiter into an clever, flexibly controllable security system.

Fashionable restraint programs already intervene in accidents at a really early stage. Within the occasion of an unavoidable crash, the belt tightens across the physique earlier than the crash (pre-tensioning) to scale back belt slack and decelerate it in a managed method after the impression and at last switch it forwards into the airbag. The programs are primarily based on consultant, standardized check topics (dummies). In future, the NCAP crash check will demand even higher safety for particular person car occupants.

“The calls for on the adaptivity of security programs are growing – each within the expectations of finish clients and within the NCAP check standards. Our new belt system makes it simpler for car producers to fulfill the elevated necessities and particularly reduces the implications of accidents by adapting even higher to the occupant,” Rudolf Stark, Head of ZF’s Passive Security Expertise Division, stated.

With the intention to scale back the forces performing on the physique within the occasion of an accident, many seat belt programs have already got a two-stage controllable load limiter (SLL). This was an vital step in the direction of adaptivity. To supply much more flexibility, ZF now provides its belt tensioner with a number of switchable load limiter (MSLL). It has a multi-stage design and may differ the restraining forces even higher over the whole course of the crash. The system makes it potential to reply individually to individuals of various stature and to regulate the belt forces appropriately.

Sooner or later, the trail to extra variability in belt forces will lead through the sensory recording of the inside to be able to acknowledge even higher which persons are sitting the place and which belt forces are to be utilized individually within the occasion of a critical or minor collision. Numerous sources will likely be used for this, the discharge stated.
