    摘要: A communication system (10) for use in a vehicle occupant restraint system (12). A central controller (14) is connected to a plurality of restraint devices (16) by a power and communication conductor (20). A signal function (28), via a voltage modulator (30), of the central controller (14) sequentially outputs voltage modulation messages to the restraint devices (16) on the conductor (20). The application sequence of the voltage modulation messages corresponds to a predetermined sequence of the restraint devices (16). A signal function (40), via a current draw modulator (42), in each of the restraint devices (16) outputs current modulation messages to the central controller (14) on the conductor (20). The application of the current modulation message from each respective restraint device (16) coincides with the outputting of a voltage modulation message from the central controller (14) to another specified one of the restraint devices.

    摘要: An occupant restraint system (10) for a vehicle (22) has a plurality of controllable occupant restraint system devices (12). The plurality of devices (12) includes sensor devices (e.g., 12E) and/or occupant restraint devices (e.g., 12A). Each restraint system device (12) has programmable control circuitry (18) for permitting control of the respective restraint system device by a central controller (38). A control interconnection (44) connects the central controller (38) and the restraint system devices (12). Electronic switches (54) are connected in series along a line (46A) of the control interconnection (44). Each of the switches (54) is associated with one restraint system device (12). Each of the switches (54) regulates communication between the central controller (38) and any device(s) (12) (e.g., devices 2-N) downstream of the associated device (e.g., device 1). The control circuitry (18) causes the associated switch (54) to "close" and permit communication between the central controller (38) and the device(s) (e.g., device 12-N), if any, downstream of the one restraint system device. The permitted communication is in response to the central controller (38) programming the control circuitry (18) of the one restraint system device. Methods for providing and using the vehicle occupant restraint system (10) are also provided.
