Dear.. why we should admit a wrong thing. We are here to educate eachother on different topics.
As far as question.. this is not an airbag. If I go by your statement then Toyota did a good job by introducing parachute. .
Air bag has horizontal or vertical creases stiched.
Toyota introduced side/curtain airbags in lexus GX and Landcruiser in model year 2003 onwards.
Also I have a difficult to understand why that green shade on Driver Side windscreen on the outsde?
Curtain airbag comes in one piece all the way from A pillar to C.. so it will remain hanging inside the vehicle not outside common sense is the bag will not fly outside. The B pillar will keep it inside. For your understanding I am placing a typical /generic curtain airbag below. They have air or no air the curtsin will remain inside..



Landcruiser airbags.
