Inflatable restraint system including an optical image sensor

摘要

An inflatable restraint system for a vehicle includes an airbag housing (7) and an airbag (9) located therein. An inflator assembly (5) is provided for inflating the airbag. A crash sensor (20) provides a first signal upon detection of at least one predetermined condition indicative of a crash. The restraint system also includes at least one optical image sensor (28) for detecting at least one occupant condition and, in response thereto, for providing a second signal. The second signal determines at least one parameter concerning inflation of the airbag. A controller is responsive to the first and second signals and provides a third signal to the inflator assembly. The inflator assembly inflates the airbag in accordance with the first and second signals.
