Abstract

A structure for a motor vehicle, particularly a passenger car, includes a front wall delimiting a passenger cabin toward the front, which extends between lateral vehicle pillars of the structure, and a carrier element which extends in transverse direction of the vehicle. The carrier element is supported by a front side of the front wall and at least to some extent overlaps the lateral vehicle pillars.

First claim

What is claimed is:

1. A structure for a motor vehicle, comprising:
a front wall delimiting toward a front in a longitudinal direction a passenger cabin of the motor vehicle;
lateral vehicle pillars of the motor vehicle, the front wall extending between the lateral vehicle pillars;
a carrier element extending in a transverse direction of the motor vehicle, the carrier element being supported by a front side of the front wall and, at least to some extent, overlapping the lateral vehicle pillars; and
at least one support element configured for at least one of a spring and damping element of a chassis of the motor vehicle, wherein
the support element is supported by the carrier element in the longitudinal direction of the motor vehicle.

2. The structure according to claim 1 , wherein
at least one of the front wall, the support element and the lateral vehicle pillars are made at least substantially of a fiber-reinforced plastic.

3. A structure for a motor vehicle, comprising:
a front wall delimiting toward a front in a longitudinal direction a passenger cabin of the motor vehicle;
lateral vehicle pillars of the motor vehicle, the front wall extending between the lateral vehicle pillars; and
a carrier element extending in a transverse direction of the motor vehicle, the carrier element being supported by a front side of the front wall and, at least to some extent, overlapping the lateral vehicle pillars,
wherein the carrier element is supported at a first portion thereof by the front wall and at a second portion thereof by the lateral vehicle pillars,
wherein the front wall includes a front wall cross member, and
wherein the front wall cross member supports the carrier element.

4. The structure according to claim 3 , wherein
the carrier element overlaps, at least in sections, the front wall cross member towards a front in the longitudinal direction of the motor vehicle.

5. The structure according to claim 1 , wherein the carrier element is adhesively bonded with at least one of the front wall, the lateral vehicle pillars, and the front wall cross member.

6. The structure according to claim 3 , wherein
the carrier element is at least substantially made of a fiber-reinforced plastic.

7. The structure according to claim 6 , wherein
the carrier element at least substantially overlaps the front side of the front wall.

8. The structure according to claim 3 , further comprising:
a vehicle floor, wherein
the carrier element is supported by the vehicle floor.

9. The structure according to claim 8 , wherein
the vehicle floor includes a tunnel element extending in the longitudinal direction of the motor vehicle, and
the carrier element is supported by the tunnel element bypassing the front wall.

10. The structure according to claim 3 , further comprising:
at least one gap formed between the front wall and the carrier element; and
a bridging element arranged in the gap, the bridging element being supported by the front wall and the carrier element.

11. The structure according to claim 10 , wherein
the carrier element is provided with at least one reinforcement element that reinforces the carrier element.

12. The structure according to claim 11 , wherein
at least one of the bridging element and the reinforcement element is made at least substantially of a metallic material.

13. The structure according to claim 12 , wherein
at least one of the bridging element and the reinforcement element includes at least one fastener by which a front module of the motor vehicle is fastenable to the structure.

14. A method for producing a structure for a motor vehicle, the method comprising the acts of:
providing a front wall delimiting a passenger cabin toward a front in the longitudinal direction of the motor vehicle, the front wall extending between lateral vehicle pillars that are provided;
arranging a carrier element so as to overlap the lateral vehicle pillars at least in sections and to be supported by a front side of the front wall, the carrier element extending in a transverse direction of the motor vehicle;
supporting the carrier element at a first portion thereof by the front wall and at a second portion thereof by the lateral vehicle pillars, wherein the front wall includes a front wall cross member; and
supporting the carrier element with the front wall cross member.

15. The method according to claim 14 , further comprising the act of adhesively bonding the carrier element with at least one of the front wall, the lateral vehicle pillars and a front wall cross member configured to support the carrier element.

16. The method according to claim 14 , further comprising the act of:
forming the carrier element at least substantially of a fiber-reinforced plastic.

17. The method according to claim 16 , wherein the arranging of the carrier element is carried out so that the carrier element at least substantially overlaps the front side of the front wall.

18. The method according to claim 17 , further comprising the act of:
supporting the carrier element by a tunnel element of a vehicle floor, the tunnel element extending in a longitudinal direction of the motor vehicle.
