ABSTRACT:
An apparatus (10) includes a crash sensor (49) which senses a crash event and provides a signal (50) indicative of the crash event. A transmitter (54) transmits a signal (58) in response to the crash sensor signal (50). A receiver (60), which is separated from the transmitter (54), receives the transmitter signal (58) and provides a control signal (80) upon receiving the transmitter signal (58). A buckle switch (34) is operable to detect a belted or an unbelted condition of a seat belt system (18). The apparatus (10) also includes an actuatable pretensioner device (49) which actuates to help to protect a vehicle occupant during a crash event. A power switch (82) receives the control signal (80) to connect the pretensioner device (49) electrically with a power source (35, 84) in response to the power switch (82) receiving the control signal (80) while the buckle switch 34 is detecting a belted condition.
