Automobile airbag deactivation system
First Claim
1. A system for deactivating an automotive airbag inflating system comprising airbag control circuitry, an airbag actuator, and an airbag, the deactivating system comprising:
- an interrupt switch operably proximate the airbag inflating system and configured to prevent the airbag from being inflated when opened; and
a switch control configured to open the interrupt switch, the switch control including an access control device for preventing the switch from being opened by non-emergency personnel.

Abstract
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.

9. A method of preventing automotive airbag inflation in a system present in an automobile, the system including airbag control circuitry, an airbag actuator, and an airbag, the airbag control circuitry activating the airbag actuator in response to sensing an automotive impact, the airbag actuator inflating the airbag after being activated by the airbag control circuitry, the method comprising:
-
providing an interrupt switch and a switch control, the interrupt switch configured to prevent the airbag from being inflated when opened, the switch control configured to open the interrupt switch and including an access control device for preventing the interrupt switch from being opened by non-emergency personnel; and
operating the switch control, thereby opening the interrupt switch and preventing the airbag from being inflated. - View Dependent Claims (10, 11, 12, 13, 14, 15)
