The invention relates to an ignition unit ( ) suitable for triggering an active system, such as an airbag or safety belt. The ignition unit comprises an ignition charge ( ) located in a housing ( ), which can be fired by means of an ignition bridge ( ) positioned on a support element ( ), as well as at least one contact pin ( ) which protrudes from the housing ( ) and via an electronic ignition system ( ) is electrically connected to the ignition bridge ( ). The electronic ignition system ( ) is surrounded by an envelope ( ) made of a shock-absorbing material. The ignition bridge ( ) is not covered by the envelope ( ) so that during ignition the pressure exerted on the electronic ignition system ( ) is cushioned. This prevents damage to the sensitive electronic components of the electronic ignition system ( ) situated on the support element ( ).
