Abstract

La présente invention concerne un dispositif pour détecter une collision frontale d'une automobile. Selon cette invention, plusieurs capteurs de collision reliés à l'appareil de commande sont intégrés dans le pare-chocs (13) de l'automobile et comprennent respectivement des premiers éléments de capteur de contact (15) qui font face à l'avant du véhicule et sont situés à distance les uns des autres sensiblement dans la direction longitudinale du véhicule et des seconds éléments de capteur de contact (16) qui sont opposés à l'avant du véhicule. Ces éléments de capteur de contact permettent de produire un signal d'accélération ou un signal de vitesse en cas de collision du véhicule et représentent des unités respectivement séparées l'une de l'autre entre lesquelles se trouve une cavité libre (1, 8) formant une section de mesure.
