Air bag apparatus for a passenger seat

摘要

An air bag apparatus (18) for a front or rear passenger seat includes a child restraining system (50) detecting device for detecting whether a child restraining system (56) is mounted on the passenger seat (14) by detecting whether a webbing retractor (48) is in an automatic locking retractor mode or an emergency locking retractor mode, and an inflator controller (40) which prevents an inflator (34) for expanding an air bag body (26) from operating when it is detected by the child restraining system detecting device that the child restraining system (56) is mounted on the passenger seat (14). Accordingly, the operation of the air bag apparatus is prevented when the child restraining system (56) is used.
