Abstract

It is provided a carrier device for a motor vehicle having a base carrier which is substantially formed by an organo sheet and which extends along a main plane. The base carrier has at least one separation on which a material region is molded out from the main plane while forming at least one free space, such that said material region is spaced apart from an adjacent region of the base carrier by at least one portion, wherein the at least one free space is at least partially filled with an injection of thermoplastic material and/or with a separate insert element, such that the portion of the molded-out material region and the adjacent region are connected to one another thereby.

First claim

The invention claimed is:

1. A carrier device for a motor vehicle having a base carrier which is substantially formed by an organo sheet and which extends along a main plane,
wherein the base carrier has at least one separation on which a material region is molded out from the main plane while forming at least one free space, such that said material region is spaced apart from an adjacent region of the base carrier by at least one portion, wherein the at least one free space is at least partially filled with an injection of thermoplastic material, such that the portion of the molded-out material region and the adjacent region are connected to one another thereby.

2. The carrier device as claimed in claim 1 , wherein the at least one free space is defined by at least two edges spaced apart from one another.

3. The carrier device as claimed in claim 2 , wherein at least one of the at least two edges of the at least one free space is formed by an adjacent edge of the separation and wherein the at least two edges are spaced apart from one another at least transversely to the main plane, and
wherein at least one of the at least two edges of the at least one free space is formed by a folded edge which is formed by molding-out the material region.

4. The carrier device as claimed in claim 2 , wherein the at least two edges of the at least one free space in each case are spaced apart therefrom transversely to the main plane.

5. The carrier device as claimed in claim 2 , wherein the at least two edges of the at least one free space are at least partially connected together by the injection.

6. The carrier device as claimed in claim 1 , wherein the at least one separation is configured by rolling, pressing, cutting, punching, deep-drawing and/or stamping in the base carrier.

7. The carrier device as claimed in claim 1 , wherein at least one of the at least one separation is provided on an outer edge of the base carrier.

8. The carrier device as claimed in claim 1 , wherein the injection forms an interface for attaching and/or supporting at least one functional element to be secured to the carrier device.

9. The carrier device as claimed in claim 1 , wherein the injection forms a deformation element of the carrier device which is configured at least partially to dissipate mechanical energy acting on the carrier device by deformation and/or forms a reinforcement between the material region and the adjacent region of the base carrier.

10. The carrier device as claimed in claim 1 , wherein the injection completely covers at least one surface of the molded-out material region so that the thermoplastic material extends over a wall formed by the molded-out material region and at least partially bordered by the at least one free space and in this case partially or entirely fills the free space.

11. The carrier device as claimed in claim 1 , wherein the base carrier comprises a plurality of separations.

12. The carrier device as claimed in claim 1 , wherein the base carrier comprises at least two separations and in addition to the material region molded out from the main plane comprises at least one further material region molded out from the main plane.

13. The carrier device as claimed in claim 11 , wherein the material region adjoins a plurality of separations and is molded out from the main plane, forming at least one free space.

14. The carrier device as claimed in claim 1 , wherein the material region is molded out from the main plane such that a tab-like structure is formed.

15. The carrier device as claimed in claim 1 , wherein a channel is formed in the base carrier and the material region is molded out from the main plane in a region of the channel.

16. The carrier device as claimed in claim 1 , wherein the material region and/or a region of the base carrier adjacent to the material region is molded out from the main plane such that a structural element of the carrier device is formed.

17. The carrier device as claimed in claim 16 , wherein the carrier device comprises a region in which a plurality of structural elements are arranged in order to influence in a specific manner the stiffness of the carrier device and/or in order to dissipate mechanical energy acting on the carrier device and thus to counteract a malfunction of the carrier device.

18. The carrier device as claimed in claim 17 , wherein the at least one free space is defined by at least two edges spaced apart from one another and the at least two edges of the at least one free space are formed by adjacent edges of the separation and are spaced apart from one another at least transversely to the main plane;
wherein a structural element adjoins one respective edge of the separation;
wherein the two structural elements together define a direction of extension, along which the two structural elements are arranged in succession, and an injection of thermoplastic material connects together the two structural elements such that the injection in each of the two structural elements extends in the direction of extension away from the free space and in this case in each case comprises an extent which corresponds to at least 25% of the extent of the respective structural element in the direction of extension.

19. The carrier device as claimed in claim 1 , wherein the at least one free space is at least also partially filled with a separate insert element.

20. The carrier device as claimed in claim 1 , the at least one separation is spaced apart from the outer edge of the base carrier.

21. The carrier device as claimed in claim 19 , wherein the separate insert element is produced from a metal material and is connected to the base carrier by at least one of adhesive bonding, ultrasonic welding, riveting, screwing and/or encapsulation by thermoplastic injection-molding.

22. A method for producing a carrier device for functional elements of a motor vehicle, the method comprising:
forming a base carrier from an organo sheet, wherein the base carrier extends along a main plane and wherein at least one separation is formed in the base carrier,
molding a material region out from the main plane on the separation, forming at least one free space, such that the molded-out material region is spaced apart from an adjacent region of the base carrier by at least one portion, and
at least partially filling the at least one free space with an injection of thermoplastic material, such that the at least one portion of the molded-out material region and the adjacent region are connected to one another thereby.
