Controlling activation of restraint devices in a vehicle

An apparatus for activating a selected one or more restraint devices located in a vehicle, comprising:

• a plurality of restraint devices located in a vehicle including at least a first restraint device and a second restraint device;
• a plurality of explosive transfer lines connected to said plurality of restraint devices, said plurality of explosive transfer lines including at least a first explosive transfer line connected to said first restraint device and a second explosive transfer line connected to said second restraint device;
• a control unit for use in controlling activation of at least said first and second restraint devices, said control unit being a single control unit that controls said activation of said first and second restraint devices, said control unit having a housing and including a processor and a circuit board;
• and
• a plurality of circuit elements including at least a first circuit element and a second circuit element mounted to said circuit board, each of said plurality of explosive transfer lines being connected between said plurality of circuit elements and said plurality of restraint devices including said first explosive transfer line being connected between said first circuit element and said first restraint device and said second explosive transfer line being connected between said second circuit element and said second restraint device;
• wherein said control unit receives a sensor input and said processor thereof, after said first control unit receives said sensor input, controls activation of at least said first and second circuit elements and said activation of said first circuit element ignites said first explosive transfer line and said activation of said second circuit element ignites said second explosive transfer line.
