Apparatus for inflating an inflatable vehicle occupant restraint
First Claim
1. An apparatus for inflating an air bag comprising:
- a first source of inflation fluid actuatable to produce a first volume of inflation fluid;
a second source of inflation fluid actuatable to produce a second volume of inflation fluid which differs from said first volume;
a temperature sensor for providing a temperature signal indicative of the temperature of the apparatus;
a control system operatively connected to the temperature sensor, said control system actuating said first and second sources of inflation fluid; and
a delay circuit coupled to said temperature sensor and said control system, said delay circuit being responsive to the temperature signal for delaying the actuation of one of said first and second sources for a predetermined period of time after actuation of said other one of said first and second sources.

Abstract
An apparatus (10) for inflating an air bag (12) includes a first source (22) of inflation fluid actuatable to produce a volume of inflation fluid and a second source (24) of inflation fluid actuatable to produce a volume of inflation fluid. The apparatus (10) also includes a temperature sensor (72) for providing a temperature signal indicative of the temperature of the apparatus (10) and a control system (50) operatively connected to the temperature sensor (50). The control system (50) actuates the first and second sources (22, 24) of inflation fluid. The apparatus (10) further includes a delay circuit coupled (51) to the temperature sensor (72) and the control system (50). The delay circuit (51) is responsive to the temperature signal for delaying the actuation of one of the first and second sources (22, 24) for a predetermined period of time after actuation of the other one of the first and second sources (22, 24).
