Patent

CA 2145051

An occupant restraint device (10) for a vehicle includes an air bag (16) mounted in the vehicle door (14) and an accelerometer (30) for measuring sideways acceleration of the door (14). A controller (20) monitors the accelerometer output (34, 36) and determines if the door (14) is in a door opening event or if the vehicle is in a sideways crash condition. The controller (20) actuates the air bag (16) if a vehicle crash condition is detected and disables actuation of the air bag (16) if the vehicle door (14) is determined to be opening.

Dispositif de retenue pour passager (10) comprenant un coussin de sécurité (16) monté dans la porte du véhicule (14) et un accéléromètre (30) pour mesurer l'accélération latérale de la porte (14). Un contrôleur (20) surveille les sorties de l'accéléromètre (34, 36) et détermine si la porte est dans un événement d'ouverture de porte ou si le véhicule est dans une condition d'écrasement latéral. Le contrôleur (20) actionne le coussin de sécurité (16) si une condition d'écrasement de véhicule est détectée et invalide l'activation du coussin (16) s'il est déterminé que la porte du véhicule s'ouvre.
