<p>A cross car support structure (16) of an instrument panel assembly (14) is provided for attachment to the vehicle side structure (10). The cross car support structure (16) includes a one-piece, integrally molded beam (40) preferably made entirely of plastic. The beam (40) preferably includes a plurality of laterally extending, upwardly opening, U-shaped duct channels (20) having upwardly facing edges (21). The cross car support structure (16) also preferably includes an instrument panel cover (60) including a substrate layer (67) having a bottom surface (77). The bottom surface (77) of the substrate layer (67) of the instrument panel cover (60) is continuously secured to the upwardly facing edges (21) of the beam (40) so that the continuously secured instrument panel cover (60) interconnects the upwardly facing edges (21) and stiffens the beam (40) such that the beam (40) and the continuously secured instrument panel cover (60) cooperatively provide the entire cross car support structure (16) for the instrument panel assembly (14).</p> |
