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.
