Abstract

The invention relates to a device for attaching an end of a cross-member of a driver's compartment of a motor vehicle to the assembled shell, which includes an attachment element provided with a first surface, for receiving the cross-member of a driver's compartment, and with a second surface opposite the first surface. Said device comprises first and second reinforcements extending from the second surface and each including: a base connected to the attachment element and to be attached to a portion of the vehicle, two side walls extending from the base and connected to the attachment element.

First claim

The invention claimed is:

1. A device for attaching an extremity of a driver's compartment cross member of a motor vehicle to an assembled body, said device comprising:
an attachment element including a first face designed to receive the driver's compartment cross member, and a second face opposite the first face, and two fins; and
a first reinforcement and a second reinforcement both extending from the second face, the first and second reinforcements each including a base connected to the attachment element and designed to be attached to a portion of the vehicle, and two side walls extending from the base and connected to the attachment element,
wherein the two fins extend from the second face and one of the two side walls of each of the first and second reinforcements is attached to the corresponding one of said fins by a spot weld.

2. The device as claimed in claim 1 , wherein the base is formed as a single piece with the attachment element by bending, and the two side walls are formed as a single piece with the base by bending.

3. The device as claimed in claim 1 , wherein the first and second reinforcements are arranged at the longitudinal extremities of the attachment element.

4. The device as claimed in claim 1 , wherein at least one of the two side walls of each of the first and second reinforcements is attached to the second face of the attachment element by a weld seam.

5. The device as claimed in claim 1 , further comprising a first member for attaching the driver's compartment cross member to the attachment element formed at the first reinforcement and a second member for attaching the driver's compartment cross member formed at the second reinforcement.

6. The device as claimed in claim 1 , wherein a section of each of the first and second reinforcements is defined, in a plane perpendicular to a direction said first and second reinforcements extend by an open line having a “U” shape.

7. The device as claimed in claim 1 further comprising a plane of symmetry perpendicular to the attachment element that passes between the first and second reinforcements.

8. An arrangement for the motor vehicle including the attachment device as claimed in claim 1 , wherein the first and second reinforcements extend from the attachment element towards the front of the motor vehicle, the attachment device is mounted on a portion of the motor vehicle, and the driver's compartment cross member is attached to the attachment device.

9. The arrangement as claimed in claim 8 , wherein the portion of the motor vehicle is a right-side or left-side A-pillar inner panel, and at least one of the first and second reinforcements is welded to an internal face of said A-pillar inner panel oriented towards an inside of the motor vehicle.

10. The arrangement as claimed in claim 9 , further comprising an external element welded to an external face of said A-pillar inner panel oriented towards an outside of the motor vehicle.

11. The arrangement as claimed in claim 10 , wherein the external element has two partitions extending from the external face of the A-pillar inner panel and arranged such as to enable transmission of a transverse force applied to the motor vehicle between the driver's compartment cross member and said external element if the vehicle suffers a frontal impact.

12. The arrangement as claimed in claim 11 , wherein the two partitions are aligned respectively with one of the two side walls of said first reinforcement and one of the two side walls of said second reinforcement.

13. The arrangement as claimed in claim 9 , wherein the A-pillar inner panel includes a slot enabling a passage of a wing of the external element welded to the first face of the attachment device.

14. A motor vehicle comprising:
the arrangement as claimed in claim 8 .

15. The device as claimed in claim 1 , wherein the attachment device is a metal part.

16. An arrangement for the motor vehicle comprising:
an attachment device, the attachment device including an attachment element, a first reinforcement, and a second reinforcement; and
an external element,
wherein the attachment element including a first face, a second face opposite the first face, and two fins,
wherein the first and second reinforcements extending from the attachment element towards a front of the motor vehicle, the attachment device is mounted on a portion of the motor vehicle, and a driver's compartment cross member is attached to the attachment device,
wherein the portion of the motor vehicle being a right-side or left-side A-pillar inner panel, and at least one of the first and second reinforcements being welded to an internal face of said A-pillar inner panel oriented towards an inside of the motor vehicle, and
wherein the external element being welded to an external face of said A-pillar inner panel oriented towards an outside of the motor vehicle, and the external element having two partitions extending from the external face of the A-pillar inner panel and being arranged to enable transmission of a transverse force applied to the motor vehicle between the driver's compartment cross member and said external element if the vehicle suffers a frontal impact.

17. An arrangement for the motor vehicle comprising:
an attachment device, the attachment device including an attachment element, a first reinforcement, and a second reinforcement; and
an external element,
wherein the attachment element including a first face, a second face opposite the first face, and two fins,
wherein the first and second reinforcements extending from the attachment element towards a front of the motor vehicle, the attachment device is mounted on a portion of the motor vehicle, and a driver's compartment cross member is attached to the attachment device,
wherein the portion of the motor vehicle being a right-side or left-side A-pillar inner panel, and at least one of the first and second reinforcements being welded to an internal face of said A-pillar inner panel oriented towards an inside of the motor vehicle, and
wherein said A-pillar inner panel including a slot enabling a passage of a wing of the external element welded to the first face of the attachment device.
