Arrangement of devices for the protection of vehicle occupants

Claim 1

Arrangement of devices (A, B, G) for the protection of occupants in a vehicle (F) whose occupants are to be protected in the event of a crash by a plurality of protective devices - for example airbags, overroll bars and/or seat-belt pretensioning devices - which can be actuated by means of an electrically detonated explosive charge, - having at least one crash sensor (S), - having an evaluation unit (A) which receives the sensor signals and evaluates with reference to the type of crash and/or severity of the crash, and - having at least two, mutually separate detonator units (B, G) which are distributed over the vehicle (F) the circuit of which (B, G) in each case contains, for the purpose of precautionary storage of the energy required to detonate the explosive charge assigned to them (B, G), one or more dedicated detonating capacitors (E) which (E) for their part at the prompting of the evaluation unit (A) trigger the protective devices depending on need, characterized in that - the arrangement contains an evaluation device (A), containing the evaluation unit (A), and a plurality of detonating devices (B, G) which are spatially distributed over the vehicle (F) and contain the detonator units (B, G) including the detonating capacitors (E), - the crash sensor (S) / the crash sensors (S) is/are mounted near or in the evaluation device (A), and - the line (D) between the evaluation device (A) and the detonating devices (B, G) is a data line (D) having time windows for serial transmission of output signals of the evaluation unit (A) as digital data.
