Patent number: 6601514Abstract: 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).Type: GrantFiled: July 5, 2001Date of Patent: August 5, 2003Assignees: Dynamit Nobel GmbH Explosivstoff-und Systemtechnik, Temic Telefunken Microelectric GmbH, TRW Airbag Systems GmbH & Co., KG, Unax AGInventors: Anton Bretfeld, Gerhard Kordel, Horst Laucht, Erwin Caflisch, Richard Baur, Michael Bischoff, Gunter Fendt, Stefan Schwehr

Patent number: 6499404Abstract: In ignition elements where the energy required to ignite the charge is produced using a laser source, the laser light is injected by means of an optical fiber or a laser optics system enabling the laser light to be focused onto the charge at the required intensity for ignition. Transmission losses and injection losses occur while the laser light is transmitted by means of optical devices or optical fibers. Known ignition devices are also complicated in terms of construction. According to the invention, the laser light source is a laser diode (3) and the explosive (4) that is to be ignited is arranged directly on the part (12) of the housing (8) of the laser diode (3) that allows the laser light (13) to pass through it.Type: GrantFiled: April 13, 2001Date of Patent: December 31, 2002Assignee: Dynamit Nobel GmbH Explosivstoff-und SystemtechnikInventors: Heinz Kern, Gerhard Kordel

Patent number: 5291014Abstract: A passive safety device comprises a sensor unit for determining vehicle accelerations and decelerations, an evaluating unit for evaluating the output signal of the sensor unit, and a triggering unit for the activation of an occupant protection system upon the reception of a trigger signal, to protect the occupants from injuries. The individual units of the safety device are connected by way of optical lightguides, i.e. the communication among the individual units takes place through optical light signals. The sensor unit has an optical-mechanical acceleration sensor with at least one input lightguide, light being transmitted to the acceleration sensor by way of this lightguide. This light is transmitted within the acceleration sensor to at least one output lightguide. The optical system of the acceleration sensor arranged between the two lightguides is exposed to the accelerations to be detected and changes its optical properties in dependence on the magnitude of the acceleration forces.Type: GrantFiled: July 31, 1992Date of Patent: March 1, 1994Assignee: Dynamit Nobel AktiengesselschaftInventors: Uwe Brede, Gerhard Kordel, Wolfram Seebeck, Horst Wellner
