Embodiment Construction

[0027] In the drawings, the same reference numerals designate the same or similar elements. figure 1 and 2 Having been introduced in the background section, we will now refer to the image 3 , image 3 A sectional view of an arrangement formed by a sash lower beam and a bulkhead according to the invention is shown.

[0028] According to a preferred embodiment of the invention, the sash lower cross member 19 has at least one stamping 21 on a joint edge 23 which is welded to the front bulkhead 3 . At least one stamped portion 21 is aligned with the opening 15 in the upper part of the front bulkhead 3 . Preferably, the number and arrangement of the stampings 21 are selected such that each opening 15 in the upper part of the front bulkhead 3 is aligned with the stampings 21 . The number of the stamping parts is, for example, three. Each embossing 21 forms a relief extending in the direction of the engine compartment 5 , ie in the direction of the vehicle floor.

Abstract

The invention relates to a windshield opening lower cross member (19) intended to be fixed to a front bulkhead (3) which in its upper part has at least one aperture (15) for the passage of a fastener (13) for the attachment of an instrument panel, said windshield opening lower cross member (19) comprising at least one pressed feature (21) positioned so that it aligns with at least one aperture (15) situated in the upper part of the front bulkhead (3) and forming a relief extending towards the engine compartment (5). The windshield opening lower cross member (19) thus forms housings able to accept the fasteners (13) so as to isolate them from the engine compartment (5).

Description

technical field [0001] The present invention relates to a sash panel of a vehicle, a vehicle including the sill panel, and a method for manufacturing the sill panel. Background technique [0002] figure 1 Shown is a conventional assembly formed of a window opening lower beam 1 and a bulkhead 3 on which a vehicle instrument panel is fitted. The lower cross member 1 for the window opening is a body structure element formed from a stamped sheet part which extends transversely along the inner edge of the windshield opening. The front bulkhead 3 likewise extends transversely and lies substantially below the lower cross member 1 of the window opening, which is connected to the vehicle floor (not shown). The bulkhead 3 is fastened to the lower cross member 1 of the window opening in a final manner, for example by welding the joint edges. [0003] figure 2 A sectional view of the assembly along cutting line A-A is shown with the supplementary elements fitted. Once fixed to eac...
