摘要： The invention relates to a pyrotechnical actuator unit (10) for actuating a vehicle safety system, including a pyrotechnical igniter (12) and an outer housing (14) made of a plastic material accommodating the pyrotechnical igniter (12), the outer housing (14) breaking by activation of the igniter (12). The outer housing (14) is made up of a first plastic part (18) and a second plastic part (20), the two plastic parts (18, 20) being permanently connected with each other.The invention further concerns a gas bag module having such an actuator unit (10), and a method of manufacturing a pyrotechnical actuator unit (10), including a pyrotechnical igniter (12) and an outer housing (14) accommodating the pyrotechnical igniter (12), the outer housing (14) being made up of a first housing part (48) and a second housing part (50), the method including the following method steps: The first housing part (48) is first produced to have a recess for the pyrotechnical igniter (12), followed by insertion of the pyrotechnical igniter (12) into the recess. Finally, the second housing part (50) is injection-molded onto the pyrotechnical igniter (12) and onto a first end (34) of the first housing part (48), so that a receiving space (24) for the pyrotechnical igniter (12) is essentially closed.
