Passenger Air Bag Module

Driver And Passenger Air Bag Module Inflator:

The driver, passenger and side air bag modules consist of the following components which cannot be disassembled:
^ Inflator
^ Bag
^ Container
^ Cover

The inflator is screwed into a metal cup-shaped container. The bag is then folded on top of the inflator and the whole subassembly is enclosed by the cover.






The passenger air bag module is located above the glove compartment and is integrated into the instrument panel top to provide an unobtrusive appearance. The cover is a one piece moulding held by five clips and a short retaining strap. As the air bag deploys, the cover is forced free of the clips, but remains attached to the instrument pad panel by the short retaining strap.

The purpose of the inflator is to generate the gas needed to fill the air bag. It consists of a high strength steel casing filled with a solid propellant charge and an electrically activated igniter. The igniter is activated by a signal from the electronic control module which in turn ignites the propellant charge. The very rapid burning of the propellant produces sufficient gas to fill the air bag(s). As the gases expand they cool, preventing heat damage to the bag. The passenger air bag module has two inflators and bag having a filled volume of 60 liters.

The bag is a one piece woven item with a silicon coating to provide flame and heat protection in the vicinity of the inflator. The shape of the bag is tailored to the vehicle proportions.
