The actuation device has nail-shaped contact pins (1), the heads (3) of which project into an ignition chamber (8), with the ends of a resistor wire (6) being attached to the heads (3) of the contact pins (1). The detonator (9) which fills the ignition chamber (8) is a detonator which is free-flowin

The actuation device has nail-shaped contact pins (1), the heads (3) of which project into an ignition chamber (8), with the ends of a resistor wire (6) being attached to the heads (3) of the contact pins (1). The detonator (9) which fills the ignition chamber (8) is a detonator which is free-flowing during the manufacture of the device, which envelopes the heads (3) of the contact pins (1) and the resistor wire (6) and which subsequently solidifies. The contact pins are surrounded by an electrically conductive extension (23) of the housing of the actuation device, so that a spark gap (F) is formed here; to discharge overvoltage, several sparks can flash over this gap simultaneously.

1. In an actuation device for a passenger protection device in a motor vehicle, comprising two nail-shaped contact pins, each having a head and a neck extending away from the head, which are fitted into an adapter ring filled with electrically insulating material, a cap-shaped housing placed on top of the adapter ring, forming an ignition chamber between the adapter ring and the housing and a resistor wire electronically connected between the heads of the contact pins located in the ignition chamber, the ignition chamber being filled with a detonator, the improvement wherein a portion of the necks of the contact pins are sealed in a glass material surrounded by the adapter ring, and wherein the heads of the contact pins project into the ignition chamber and together with the resistor wire are completely surrounded by a detonator which is free-flowing during the manufacture of the actuation device and which subsequently solidifies, causing the detonator to be anchored on the heads of the contact pins.
