PCT No. PCT/SE91/00361 Sec. 371 Date Jun. 2, 1993 Sec. 102(e) Date Jun. 2, 1993 PCT Filed Sep. 19, 1991 PCT Pub. No. WO92/01461 PCT Pub. Date Jun. 11, 1992.A test circuit for detection of malfunctions in an electric triggering device (10, 11) for protection of vehicle occupants. The triggering devices (10, 11) are arranged with a first connector (12) connected to earth (13) and a second connector (14) connected to a control unit for supply of a triggering current to the triggering devices when detecting a triggering condition. The test circuit comprises a voltage regulator (17), a current generator (18,19) connected in series between the voltage regulator and the connection of the triggering devices (10,11) to the control unit for generating a test current to the triggering devices, and two voltage comparators (24,25) connected between the earth connection (13), the connection (14) to the control unit and the voltage regulator for detecting the voltage across the triggering devices (10,11).

JP2002509828	INDUSTRIAL APPLICABILITY A occupant protection system having a plurality of control modules for triggering an occupant protection device connected so as to be able to communicate by a central device, a sensor, and a bus system.
