Abstract
A device for wireless transmission of a trigger signal, in particular for a restraint system, which has a redundancy path to ensure reliable triggering of a restraint system, is proposed. On a primary side of a transmitter a redundancy unit is arranged; this generates a redundancy signal from a trigger command, the redundancy signal being detected by an enable unit on the secondary side in order to enable a trigger circuit for the restraint system, the trigger circuit then being triggered by an evaluation unit on the secondary side via a trigger signal. The trigger circuit triggers a restraint system.
Claims13
A device for wireless transmission of a trigger signal for a restraint system, comprising:
- a transmitter (1), a first evaluation unit (8) and a trigger signal generator (9) being provided on a primary side (13) of the transmitter (1), the trigger signal generator (9) sending a trigger command to the first evaluation unit (8), which converts the trigger command into a trigger signal and sends it via said transmitter (1), and a second evaluation unit (2), which receives the trigger signal and triggers a trigger circuit (4) for the restraint system (5), being arranged on a secondary side (7) of the transmitter (1), wherein on the primary side (13) a redundancy unit (11) is connected to the trigger signal generator (9), the trigger signal generator (9) transmitting the trigger command to the redundancy unit (11), the redundancy unit (11) converting the trigger command into a redundancy signal, and an enable unit (3) which enables the trigger circuit (4) in dependence on the redundancy signal is arranged on the secondary side (7).
