CA 2241399

An apparatus and method for controlling the deployment of airbags facing seats in a vehicle is provided. A seat is provided having a plurality of sensors and a computer output from said plurality of sensors, and an airbag is positioned opposite the seat. The airbag is deployed when the plurality of sensors exceed a threshold. The computer stores data concerning weight, center of gravity, and load distribution of an occupant, as determined from readings from the sensors, and the threshold is adjusted based upon that data. Where multiple airbags are provided, the computer controls the deployment only the airbags facing occupied seats when the threshold is exceeded.

Dispositif et méthode servant à régir le déploiement des coussins gonflables situés face aux sièges dans un véhicule. Le siège est doté de plusieurs capteurs reliés à un ordinateur et un coussin d'air est situé face au siège. Le coussin d'air est déployé lorsque les capteurs enregistrent des données excédant le seuil limite déterminé. L'ordinateur enregistre des données recueillies par les capteurs relativement au poids, au centre de gravité et à la répartition du poids de l'occupant du siège, et le seuil limite est ensuite réglé en fonction de ces données. Lorsque plusieurs coussins gonflables sont déployés, l'ordinateur commande le déploiement uniquement des sièges occupés lorsque le seuil limite ainsi établi est dépassé.
