Abstract

The vehicle structure comprises a body defining an engine compartment and a passenger compartment communicating with each other through an opening which the body defines between them, and a panel independent of the body and arranged to close said opening between the engine compartment and passenger compartment. The panel is composed of a rigid element having a mechanical support function and a soundproofing element of cellular structure, an instrument dashboard defining internally the ducts for an aeration system, and other accessories, all directly fixed to and supported by the panel to define with it a self-supporting sub-unit. The sub-unit is preassembled off the assembly line and is then fixed to the vehicle body by inserting it from the passenger compartment side so as to position the panel in the opening, and then fixing the panel to the body.

A vehicle structure, comprising:

(a) a body defining an engine compartment and a passenger compartment communicating with each other through an opening between them;
(b) a dividing element between the passenger compartment and engine compartment;
(c) said dividing element comprising a panel independent of said body and arranged to close said opening between the engine compartment and passenger compartment;
(d) said panel comprising a rigid element having a mechanical support function and a soundproofing element formed of expanded material of cellular structure;
(e) said soundproofing element forming a single body with said rigid element;
(f) said panel including an upper portion of cross-member form and a lower portion of bulkhead form;
(g) said rigid element defining a load-bearing framework of said panel and being embedded in said soundproofing element;
and
(h) said soundproofing element covering said upper portion of said panel on a side facing the engine compartment and said lower portion on a side facing the passenger compartment.

A vehicle structure, comprising:

(a) a body defining an engine compartment and a passenger compartment communicating with each other through an opening between them;
(b) a dividing element between the passenger compartment and the engine compartment, said dividing element including an instrument dashboard;
(c) said dividing element including a panel independent of said body and arranged to close said opening between the engine compartment and passenger compartment;
(d) said panel being composed of a rigid element having a mechanical support function and a soundproofing element formed of expanded material of cellular structure;
(e) said soundproofing element forming a single body with said rigid element;
(f) said instrument dashboard being fixed to and supported by said panel to define therewith a self-supporting sub-unit which is fixed perimetrally to said vehicle body;
(g) said panel comprising an upper portion substantially in the form of a cross-member and including bracket means for connecting to said vehicle body and at least one support bracket means for securing said instrument dashboard thereto, and a lower portion of bulkhead form having passage holes and connection means for vehicle controls and accessories;
(h) said panel including a through aperture substantially between said upper cross-member portion and said lower bulkhead portion;
(i) said rigid element defining a load-bearing framework of said panel which is embedded in said soundproofing element;
and
(j) said soundproofing element being shaped in such a manner as to cover said rigid element on a side facing said engine compartment over the entire upper portion of said panel and as far as the extent of said aperture, and on a side facing said passenger compartment over the entire portion of said rigid element below said aperture.
