Abstract
An air bag control system for passenger seat has a seated-state detection sensor provided in a seat, a proximity sensor that detects an object near an air bag apparatus, and an impact sensor that detects a deceleration at the time of an impact. If there is no detection made by the proximity sensor for a predetermined length of time after the seated-state detection sensor detects the seating of an occupant, a control device keeps the air bag apparatus in an operable state after elapse of the predetermined length of time. If there is no detection made by the proximity sensor for the predetermined length of time after the seated-state detection sensor makes detection, the control device ignores an on-state of the proximity sensor or a signal from the proximity sensor, and keeps the air bag apparatus in the operable state. With this control, even if a sitting adult extends his/her arm to an instrument panel after elapse of the predetermined length of time, the air bag apparatus is operated when the impact sensor detects a deceleration equal to or greater than a predetermined value.
