  • Externally controlled ignition unit with integrated electronic system for triggering a restraint system
    Patent number: 6601514
    Abstract: The invention relates to an ignition unit (1) suitable for triggering an active system, such as an airbag or safety belt. The ignition unit comprises an ignition charge (7) located in a housing (2), which can be fired by means of an ignition bridge (6) positioned on a support element (5), as well as at least one contact pin (13a, 13b, 13c) which protrudes from the housing (2) and via an electronic ignition system (9) is electrically connected to the ignition bridge (6). The electronic ignition system (9) is surrounded by an envelope (10) made of a shock-absorbing material. The ignition bridge (6) is not covered by the envelope (10) so that during ignition the pressure exerted on the electronic ignition system (9) is cushioned. This prevents damage to the sensitive electronic components of the electronic ignition system (9) situated on the support element (5).
