Vehicle roof having a modular, multishell structure
A vehicle roof for a passenger car, the vehicle roof having a modular, multishell structure, the vehicle roof including a variably configurable functional shell for providing stiffness to the vehicle roof and configured to be directly attached to a body shell of the vehicle and for variable accommodation of functional elements; an outside roof skin configured to be fixed to an outside surface of the functional shell with a fixing means; and at least one inside lining element configured to be fixed to an inside surface of the functional shell.
1. A vehicle roof for a passenger car, the vehicle roof having a modular, multishell structure, comprising:
a variably configurable functional shell for providing stiffness to the vehicle roof and configured to be directly attached to a body shell of the vehicle and for variable accommodation of functional elements;
an outside roof skin configured to be fixed to an outside surface of the functional shell; and
at least one inside lining element configured to be fixed to an inside surface of the functional shell;
wherein the functional shell has a cutout for a roof opening system and means for fixing mechanical and electrical components of the roof opening system, and
wherein the outside roof skin covers the cutout of the functional shell and is interchangeable with an outside roof skin having an opening matched to the cutout of the functional shell.
2. The vehicle roof of claim 1 , wherein the functional shell comprises at least one cross member, including at least one cowl of the vehicle roof.
3. The vehicle roof of claim 1 , wherein the functional shell comprises a plastic molding.
4. The vehicle roof of claim 1 , wherein the functional shell includes a recess with an area corresponding essentially to an area of an opening of the vehicle roof.
5. The vehicle roof of claim 1 , wherein the functional shell includes a water drainage system.
6. The vehicle roof of claim 1 , wherein the functional shell includes means for integration of electrical components.
7. The vehicle roof of claim 1 , wherein the functional shell includes recesses for attachment of the functional shell to the body shell of the vehicle.
8. A vehicle roof for a passenger car, the vehicle roof having a modular, multi-shell structure, comprising:
a variably configurable functional shell for providing stiffness to the vehicle roof and configured to be directly attached to a body shell of the vehicle and for variable accommodation of functional elements;
an outside roof skin configured to be fixed to an outside surface of the functional shell; and
at least one inside lining element configured to be fixed to an inside surface of the functional shell
wherein a front edge region of the functional shell a section which extends across the functional shell in a transverse direction of the vehicle and which forms a front cowl in a manner creating a front safety-relevant transverse member that provides stiffness and stability to the front area of the vehicle roof; and
wherein a rear edge region of the functional shell has a section which extends across the functional shell in the transverse direction of the vehicle and which forms a rear cowl in a manner creating a rear safety-relevant transverse member that provides stiffness and stability to the rear area of the vehicle roof.
9. The vehicle roof of claim 8 , wherein the front and rear cowls are channel shaped.
10. The vehicle roof of claim 9 , wherein the at least one inside lining element comprises a headliner that is directly attached to an underside area of the front and rear cowls.
