Abstract

A front bulkhead for a motor vehicle includes a bodyshell floor fitted with a tunnel including a lower edge, an upper edge, and two lateral sides. The lower edge and the upper edge are continuous and substantially parallel. The lower edge has no cutout at a junction with the tunnel of the bodyshell floor of the vehicle. The lateral sides have solid portions incorporating a shape of wheel arches.

First claim

The invention claimed is:

1. A front bulkhead for a motor vehicle, comprising
a bodyshell floor fitted with a tunnel comprising a lower edge, an upper edge, and two lateral sides, including a left lateral side and a right lateral side,
wherein the lower edge and the upper edge are substantially parallel continuously from the left lateral side to the right lateral side, the lower edge having no cutout at a junction with the tunnel of the bodyshell floor of the vehicle, the lateral sides having solid portions incorporating a shape of wheel arches.

2. The bulkhead as claimed in claim 1 , further comprising a first substantially vertical surface arranged at a front of the bulkhead, and a second adjacent surface inclined towards a rear of the bulkhead when the bulkhead is mounted in the vehicle.

3. The bulkhead as claimed in claim 1 , wherein the solid portions incorporating the shape of the wheel arches comprise a junction surface of substantially conical and curved form.

4. The bulkhead as claimed in claim 2 , wherein the first surface is to receive pedals and a steering column mounted thereon.

5. The bulkhead as claimed in claim 2 , further comprising an opening made in the first surface and configured to receive a separate reinforcement mounted thereon.

6. The bulkhead as claimed in claim 2 , wherein the first surface includes a blind cavity in which four threaded holes are made.

7. The bulkhead as claimed in claim 2 , wherein the second surface has a recess forming a hollow body, configured to house an end of the tunnel of the bodyshell floor of the vehicle.

8. A motor vehicle comprising:
a bodyshell floor fitted with a tunnel extending in the longitudinal direction of the vehicle; and
the bulkhead as claimed in claim 1 .

9. The vehicle as claimed in claim 8 , wherein a mastic seal is arranged along the lower edge, the upper edge, and the lateral sides of the front bulkhead.

10. The bulkhead as claimed in claim 1 , wherein the bulkhead consists of a single piece of shaped sheet metal.

11. The bulkhead as claimed in claim 7 , wherein the recess includes a surface portion that is more inclined than the second surface.

12. The vehicle as claimed in claim 8 , wherein the tunnel does not pass through the bulkhead.
