Abstract
An adaptively controlled safety restraint system (20) is disclosed which includes a safety restraint device (22, 24) operative in response to a flow of pressurized gas, and fluid means (28) having a stored energy device (30) which can be activated to produce pressurized gas which is discharged through a conduit network (34, 36) for driving the safety restraint device (22, 24). The system further includes a throttling valve assembly (32, 58) disposed between the fluid means (28) and the safety restraint device (22, 24) for controllably varying the output of the fluid means (28). The throttling valve assembly (32, 58) is controlled by an electrical signal received from a crash management controller (38).
