An automobile airbag deactivation system is provided to enable emergency services personnel to prevent uninflated airbags from inflating when crash victims are being extricated from crashed automobiles. The system would enable emergency services personnel to deactivate all airbag inflation systems. The airbag deactivation system includes an interrupt switch and a switch control. The interrupt switch is located so as to prevent airbag inflation, such as between the airbag control circuitry and the airbag actuator or between the airbag actuator and the airbag. The switch control includes a device to open the interrupt switch and an access control device. The access control device prevents deactivation of the airbag inflating system by non-emergency personnel. Embodiments of the access control device include restricted electromagnetic band communication between a signal source and a signal transducer. The transducer opens the interrupt switch to deactivate the airbag inflation system. In other embodiments, a mechanical lock is used. Keys to these locks may be made available to emergency services personnel.
L'invention porte sur un système de désactivation d'airbags d'automobiles permettant aux personnels de secours d'empêcher le gonflement inopiné des airbags non déclenchés pendant que les victimes d'un accident sont extraites d'un véhicule accidenté, la désactivation de tous les dispositifs de gonflage étant assurée par ledit personnel. Le système de désactivation comporte un interrupteur, et une commande d'interrupteur, l'interrupteur étant placé de manière à empêcher le gonflage soit entre le circuit de commande de gonflage, et l'activateur de l'airbag, soit entre l'activateur de l'airbag et l'airbag. Un dispositif de restriction limite l'accès au système au personnel de secours; dans certaines réalisations, il consiste en un transducteur électromagnétique qui ouvre l'interrupteur et désactive le système de gonflage, dans d'autres réalisations, il consiste en une serrure mécanique. Les clefs correspondantes peuvent être mise à la disposition du personnel de secours.
