1. A vehicular roof headlining, comprising a trough-shaped receiving body in a border region of the headlining and an integrated head protection restraining means, said integrated head protection restraining means comprising a plurality of inflatable gas bags, said headlining having long sides provided with a lip forming an elongated groove, said receiving body engaging said groove of said headlining, said gas bags being stowed in a folded condition in a volume substantially defined by said trough-shaped receiving body, and said gas bags forming, together with the headlining, a preassembled module.

2. A vehicular roof headlining, comprising a trough-shaped receiving body in a border region of the headlining and an integrated head protection restraining means, said integrated head protection restraining means comprising a plurality of inflatable gas bags, said gas bags being stowed in a folded condition in said trough-shaped receiving body, said gas bags forming, together with the headlining, a preassembled module, each of said gas bags being arranged in the region of a depression for receiving a grab handle, said depressions comprising through-holes provided for fastening bolts for securing said grab handles, said receiving body comprising fastener openings aligned with said through-holes for fixing both said headlining and said preassembled module by said fastening bolts.

3. A vehicular roof headlining, comprising trough-shaped receiving bodies in a border region of the headlining and an integrated head protection restraining means, said integrated head protection restraining means comprising a common source of compressed gas provided with a valve assembly, and at least two inflatable gas bags, said gas bags being connected to said common source of compressed gas and being stowed in a folded condition in said trough-shaped receiving bodies, said gas bags forming, together with the headlining, a preassembled module, a first gas bag being disposed on a first long side of said headlining and a second gas bag being disposed on a second long side of said headlining, said valve assembly being switchable for selecting which one of said two gas bags is to be inflated by said gas source.
