GF91.60-P-4041RT Windowbag Component Description

Component Identification:

The attendant air hose - when folded - is located at the side of the roof frame of the A-pillar up to the C-pillar.

The windowbag unit consists of a hybrid gas generator with the left windowbag squib or right windowbag squib and an air hose. The air hose is divided into several air chambers.

The gas generator with the left windowbag squib and the gas generator with the right windowbag squib are both located on the left or right A-pillar.

The windowbag supplements the effect of the sidebag in the event of a side-impact collision. It protects the head area of front and rear passengers in the event of a side-impact collision or an angled collision.

When in inflated condition the windowbag on the driver or passenger side fills the space between the side windows and the occupants.

It prevents the head from swinging outwards immediately after a collision and thus reduces the acceleration forces acting on the body.

In addition, the air cushion holds back glass splinters and other objects that could penetrate into the passenger compartment in the event of a side impact or subsequent rollover.

Function
The restraint systems control unit (N2/7) sends an ignition pulse to the squib in the hybrid gas generator. The burnt off squib causes solid fuel to be ignited in the fuel chamber.

A pressure builds up in the fuel chamber. This pressure then causes a bursting disk to be destroyed.

The compressed inert gas mixture can escape from the pressure reservoir through the outlet openings. The gas flowing out is guided at a high pressure in the air hose folded and stored in the roof frame.

The air hose which is now inflating tears open the inner trim on the side roof frame and enters the interior.

The air hose reaches its full volume within approximately 25 milliseconds This volume is retained for approx. three to five seconds. This serves to ensure that the protective effect is maintained for a sufficient period even during any subsequent rollovers.

The pressure now begins to drop. The gas escapes from the airbag through a filter. This then collapses.
