568
Votre véhicule est équipé de SACS DE SÉCURITÉ GONFLABLES
INTELLIGENTS (ADVANCED AIRBAGS) conçus selon les normes de
sécurité américaines applicables aux véhicules à moteur (FMVSS208).
Le système de sacs de sécurité gonflables régule la puissance de
déploiement des sacs de sécurité gonflables conducteur et passager
avant. Le système de sac de sécurité gonflable conducteur comprend le
capteur de position du siège conducteur, etc. Le système de sac de
sécurité gonflable passager avant comprend le capteur de classification
des occupants du siège passager avant, etc.
Les principaux éléments du système de sacs de sécurité gonflables SRS
sont illustrés ci-dessus. Le système des sacs de sécurité gonflables SRS
est commandé par un boîtier électronique. Ce boîtier intègre un capteur
de sécurité et un capteur de sac de sécurité gonflable.
Lorsque la violence du choc frontal ou latéral l'exige, le système de sacs
de sécurité gonflables SRS déclenche les dispositifs pyrotechniques de
gonflage (générateurs de gaz). Le déploiement rapide des sacs de
sécurité gonflables est obtenu au moyen d'une réaction chimique dans
les dispositifs pyrotechniques, qui produit un gaz inoffensif permettant
d'amortir le mouvement des occupants.
