Problems solved by technology

In particular, if it does not completely compress the front bulkhead, if it is in contact with and / or is stressed by surrounding parts, and if it is in relation to, e.g. and air-conditioning ducts with off-centre holes, there may be difficulties in fitting components that pass through or not through the baffle, which of course leads to poor acoustic sealing

Embodiment Construction

[0028] Referring to the drawings, the present invention discloses a rigid structure 10 comprising means 12 for attaching an acoustical panel 14 to the rigid structure prior to fastening the acoustical panel 14, for example with staples. positioned on this rigid structure.

[0029] According to our embodiment, the rigid structure 10 of the invention is a motor vehicle body structure for separating the engine compartment 18 from the passenger compartment 20 . A number of cables or pipes run through the structure, for example to power the various electrical or electronic components of the instrument panel or to condition the air in the passenger compartment.

[0030] The structure generally comprises in its upper part a beam 22 extending transversely, as its name implies, and a heated baffle 16 placed below the beam in a position encompassing the transverse direction and in the vertical plane. A front partition wall 17 is also placed below the baffle plate 16, and the front par...

Abstract

The invention relates to a rigid structure (10) designed to separate the engine compartment (18) from the passenger compartment (20) of a motor vehicle, said structure comprising, in its upper part, a crossmember (22) below which there extends a substantially vertical partition (16), a junction region (30) being present between these two elements (22) and (16), characterized in that the crossmember comprises extensions (12) formed in one piece with said crossmember such that, after folding, these extensions constitute positioning tabs (12A, 12B) for a soundproofing panel (14).The invention also relates to a corresponding soundproofing panel.

Description

technical field [0001] The invention relates to a rigid structure comprising means for positioning an acoustic panel, as well as to a corresponding acoustic panel. Background technique [0002] Such baffles are used in particular in motor vehicles, in which they are used to seal off the passenger compartment from the external environment. In particular, they can be fastened to the front bulkhead of a motor vehicle in order to attenuate engine-induced noise in the passenger compartment. In this case, the instrument panel generally covers at least the upper part of the sound insulation panel. [0003] In the above application, the sound baffle is placed between the bulkhead and the instrument panel, its presence dampens the vibration of the bulkhead and thus the noise generated by the engine. [0004] These acoustic panels are currently produced in the form of high-density solid panels called weights, associated with spring-acting supports such as foam layers. The assembly ...
