A passenger protection device of an automobile is triggered when a testable acceleration switch supplies a switch signal and an electrically controlled switching device is actuated by a control circuit depending on a collision. Actuation of the switching device is prevented on a triggering circuit side by a blocking device so that the passenger protection device is not triggered as a result of faulty control switching during testing of the acceleration switch.

Device for triggering and method for operating an occupant protection device of a motor vehicle using a testable acceleration switch

An airbag control device comprises a housing with a cover that enclose a printed circuit board with an acceleration sensor and electronic components. The housing and the cover have a substantially central passage, from which the housing interior is closed off. The substantially central passage has, at least in one region thereof, an asymmetrical shape that enables the control device to be installed with a single bolt having a shape complementary to that of the substantially central passage.
