Seat Belt: Description and Operation
Three-Point ELR Front Seat Belt With Pretensioner
The three-point emergency locking retractor (ELR) front seat belt pretensioner is always unlocked, allowing the passenger freedom of movement, except
in emergencies such as rapid deceleration, rapid acceleration, or hard cornering maneuvers.
The front seat belt pretensioner contains an ignitor charge and a gas generator to inflate the pretensioner. The pretensioner also includes wiring and a
connector. The connector of the pretensioner contains a shorting bar which short-circuits the pretensioner high circuit to the pretensioner low circuit
when the connector is disconnected. The shorting bar prevents current from traveling through the pretensioner during servicing. The shorting bar
disengaged when the connector is connected.
The pretensioner is an electronically controlled pyrotechnical reactor which reduce seat belt slack when it is activated with air bags.
The front seat belt pretensioner must be replaced after an accident that cause its activation.
