Abstract
A duplex harness assembly for a motor vehicle airbag occupant restraint system. The system design incorporates a connector housing for connection via a cable with a restraint system controller. The connector housing having an integrated circuit provides a duplex restraint system control. The duplex control is provided by incorporating one or more electronic elements such as diodes mounted to the circuit. One or more electronic device attachments are remotely mounted from the connector housing via pairs of conductive wires.
Claims21
An electrical harness assembly for use with a restraint system for activation of devices for vehicle restraint systems having an ECU connector connected with a restraint system controller by a connecting cable, the assembly comprising:
- a connector housing including a terminal connection configured to receive a first control signal in a first current direction and a second control signal in a second current direction opposite the first current direction from the ECU connector conductively connected to a circuit;
- the circuit defining a first and a second loop, each loop being defined as conductively connecting to the terminal connection, the first loop having a first electrical component limiting the flow of current only in the second current direction, and the second loop having a second electrical component only limiting the flow of current in the first current direction with respect to the terminal connection;
- and
- the first loop including a first electronic device attachment in series with the first electrical component and the second loop including a second electronic device attachment in series with the second electrical component.
