Beschreibung
Zusammenfassung:	A backrest device that normally supports the occupant and moves forward with said occupant during a forward impact/crash event. The device is equipped with a spring activated biased ratcheting mechanism that provides only forward movement, thus reducing the amount of dangerous rear excursion during the rebound phase, as measured by the occupant's head and torso. Un dispositif de dossier qui supporte normalement l'occupant et se déplace vers l'avant avec ledit occupant pendant un événement d'impact/impact vers l'avant. Le dispositif est équipé d'un mécanisme d'encliquetage sollicité par ressort qui assure uniquement un mouvement vers l'avant, réduisant ainsi la quantité d'excursion arrière dangereuse pendant la phase de rebond, telle que mesurée par la tête et le torse de l'occupant.
