Vehicle seat headrest, can be moved in event of vehicle collision via force transmitted to headrest supports via backrest

摘要

An external system maintains the headrest in an optimum position in relation to the force exerted on the body of the person on the seat in the event of a collision. This is achieved by transmitting movement via the backrest and rotary joints to the headrest support rods. The system is incorporated into the backrest upholstery.
