Abstract

A door assembly for a motor vehicle includes a window frame, a function carrier assembly including a function carrier fixedly connected to the window frame and a plurality of operational components accommodated in the function carrier, and an outer skin disposed on an exterior facing side of the function carrier assembly, where the plurality of operational components remain in the function carrier and the function carrier assembly remains fixedly connected to the window frame when the outer skin is removed from the exterior facing side of the function carrier, and the function carrier is connected to the window frame by at least one connection element mounted on the window frame for the reinforcement of at least one of a hinge region and a locking region of the function carrier.

Claims

1. A door assembly for a motor vehicle comprising:

a window frame,

a function carrier assembly comprising a function carrier fixedly connected to the window frame and a plurality of operational components accommodated in the function carrier, and

an outer skin disposed on an exterior facing side of the function carrier assembly,

wherein the plurality of operational components remain in the function carrier and the function carrier assembly remains fixedly connected to the window frame when the outer skin is removed from the exterior facing side of the function carrier, and

wherein the function carrier is connected to the window frame by at least one connection element mounted on the window frame for the reinforcement of at least one of a hinge region and a locking region of the function carrier.

2. A door assembly according to claim 1, wherein the function carrier is comprised of reinforced synthetic material.

3. A door assembly according to claim 2, wherein the reinforced synthetic material is comprised of a thermoplastic fiber reinforced matrix.

4. The door assembly according to claim 3, wherein the function carrier is further comprised of aluminum.

5. The door assembly according to claim 1, wherein an inwardly facing surface of the function carrier is partially covered with at least one inner panel connected to the function carrier.

6. The door assembly according to claim 1, wherein the operational components are comprised of window lifting devices, loud speaker systems, opening and closing systems and structure-reinforcing elements.

7. The door assembly according to claim 1, wherein the function carrier divides the door assembly into a wet region and a dry region.

8. The door assembly according to claim 1, wherein the outer skin is comprised of a glass fiber-reinforced synthetic material.

9. The door assembly of claim 1, wherein the outer skin disposed on the exterior facing side of the function carrier assembly is secured to the function carrier assembly by a snap connection on edge portions of the function carrier and the outer skin.

10. The door assembly of claim 9, wherein the snap connection comprises a groove-tongue joint.

11. The door assembly of claim 1, wherein the plurality of operational components are accommodated in the function carrier by being inserted in the function carrier.

12. The door assembly of claim 7, wherein the wet region is located on the exterior facing side of the function carrier and houses at least a window lifter mechanism as one of the operational components.

13. The door assembly of claim 7, wherein the dry region is located on an interior facing side of the function carrier and houses at least a loudspeaker as one of the operational components.

14. The door assembly of claim 12, wherein the dry region is located on an interior facing side of the function carrier and houses at least a loudspeaker as one of the operational components.

15. The door assembly of claim 1, wherein the connection between the function carrier and the window frame comprises a welding connection.
