against the face wall 30 of the distribution section 14 so that the openings 52 are likewise closed outside of the gas generator 10 the hook shaped holder 48 engages with the pyrotechnical device 40 thereby affixing a traction element 50 the traction element 50 is preferably a cable or a fabric strip so that it can easily be affixed to the holder 48 by means of a loop or a recess fig2 shows the section according to fig1 but now after an activation of the actuator unit 36 as a result of this activation such a high pressure builds up in the pressure chamber 47 that the piston 38 is moved in the direction of the base section 12 due to this movement the openings 52 in the base plate 44 move away from the face wall 30 furthermore the piston wall 42 slides along the circumferential wall 26 of the distribution section 14 and releases the second outflow openings 20 in this activation position generator gas can flow through the first outflow openings 18 into the airbag chamber 28 as well as through the openings 52 and through the second outflow openings 20 to outside of the airbag chamber 28 as a rule the actuator unit 36 is activated after the activation of the gas generator 10 so that a certain pressure already prevails in the distribution section 14 the actuator unit 36 has to.
