Abstract
Data bus for constraint devices, which connects a control unit to the constraint devices, which are connected to the data bus via transformers. The data is then transmitted over the data bus using frequency shift keying signals. The constraint devices are each provided in removable seats. Upon activation of the constraint devices, a deployment signal is sent to the constraint devices over a power supply line.
Claims7
A data bus for constraint devices in a vehicle, comprising:
- inductive transformers for connecting each of the constraint devices as a bus station to the data bus,
- wherein a control unit for the constraint devices is connected as another bus station to the data bus,
- wherein data is transmitted over the data bus using frequency shift keying signals, and
- wherein the data includes a start bit, a bus station identifier and an information field for evaluating a respective bus station.
