A pyrotechnical actuator unit () for a vehicle safety system includes an outer housing () made of a plastic material accommodating a pyrotechnical igniter () that when activated breaks the outer housing. The outer housing () includes first and second plastic parts () permanently connected with each other. A gas bag module may have such an actuator unit (). A method of manufacturing a pyrotechnical actuator unit () including an outer housing () accommodating a pyrotechnical igniter () and made up of first and second housing parts () includes: producing the first housing part () having a recess for the pyrotechnical igniter (), inserting the pyrotechnical igniter () into the recess, and injection molding the second housing part () onto the pyrotechnical igniter () and onto a first end () of the first housing part () to essentially close a receiving space () for the pyrotechnical igniter ().

A gas generator includes a housing having an inner wall delimiting an igniter chamber peripherally, and at least one igniter opening into the igniter chamber. The gas generator further includes a cap arranged for displacement along the inner wall and delimiting the igniter chambe, said cap having a cylindrical peripheral wall and a radially extending cover wall. The peripheral wall has a first section extending from the cover wall in displacement direction (R) and a second section extending in a direction opposite thereto. The first and second sections lie against the inner wall and guide the cap during a displacement thereof. The cover wall is turned axially into the interior of the cap.
