Claims

1. An inflatable side impact airbag for a vehicle occupant protection device, said side impact airbag comprising an upper edge to attach it in the area of an A-column and of a roof frame of a motor vehicle, said upper edge of said airbag being straight.

2. The side impact airbag according to claim 1, wherein said airbag is rolled up towards said upper edge, to form a roll that has an axis which is parallel to said upper edge.

3. The side impact airbag according to claim 2, wherein said airbag is rolled up in such a way that a side of said airbag facing a vehicle interior when said airbag is in an installed and inflated state forms an outside of said roll.

4. A method of installing a side impact airbag in the area of an A-column and of a roof frame of a motor vehicle, said side impact airbag comprising an upper edge to attach it in said area of said A-column and of said roof frame of said motor vehicle, said upper edge of said airbag being straight, and said side impact airbag being rolled up towards said upper edge to form a roll that has an axis which is parallel to said upper edge, said roll being adapted to a curvature of said A-column and of said roof frame and said upper edge of said roll being attached to said A-column and to said roof frame.
