Abstract

Dans un dispositif de sécurité pour le pare-brise d'une voiture, un protecteur (1) stratifié formé d'un élément de cadre (1a), des matériaux d'amortissement (2a, 2b) et d'un matériau de gainage (2c) qui absorbe l'impact lors d'un accident, est normalement agencé sur une partie du plafond, d'où il tombe ou glisse au moment d'un accident afin de protéger le corps d'un être humain. Un commutateur agencé sur le devant de l'automobile est actionné lorsqu'il survient un accident et un solénoïde (5) agencé sur le plafond déclenche le protecteur (1), qui tombe ou glisse en avant et qui est bloqué par un mécanisme de verrouillage (4). Le protecteur (1) peut contenir un coussin d'air (8), de sorte qu'il actionne et gonfle le coussin d'air (8) en même temps que le protecteur (1) est actionné. L'impact subi par le corps d'un être humain lors d'un accident peut être absorbé par le protecteur (1), qui se met alors en fonctionnement afin d'absorber l'impact.
