Technical description: Headlining
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The headlining is manufactured in cellular plastic and covered with fabric. In this way, the roof acts as protection as well as insulate against heat, cold and sound.
Between the headlining and the outer roof there is a number of energy absorbents fitted. The headlining and the absorbents work together to minimize personal injury in case of accidents. It is essential that these components are fitted correctly so that sufficient protection is attained.
