guard against accidental injury of a user of a vehicle seat and a mechanical system for detektierung fahrzeugaufpralls

摘要

A protection device that prevents accident-related injuries of a user of a vehicle seat, having a device which, in the event of a vehicle impact, in particular a rear impact, moves a component of the vehicle seat, in particular an upper backrest part of a backrest, from a normal operational position into a safety position, in particular pivots it through an angular region relative to a lower backrest part about an axis running transversely with respect to the longitudinal axis of the vehicle in a backrest of the vehicle seat under the effect of a torque, having locking means for fixing the component in the normal operational position, and having means for detecting the vehicle impact, which means are formed by a mechanical system which has parts which-accelerated by the effects of the vehicle impact-cancel the fixing of the component by bringing the locking means into an unblocked position.
