ABSTRACT:
Methods and apparatus for inflating airbags in vehicles. Systems for inflating airbags comprise electrical storage devices interfaced with switching devices that switch the electrical energy into an actuating subsystem to inflate the airbags. The actuating systems can be coils, which are interfaced with plates that open the airbag. The airbags are inflated with ambient or above ambient pressures. Airbag inflation systems described herein eliminate the need to use external gases which are potentially harmful to inflate the airbags. Furthermore, the use of air from the automobile's passenger compartment eliminates overpressure problems which may exist as a result of multiple airbags being inflated at one time.
