Abstract: An automobile bodyshell frame structure includes a generally elongated first panel member, and a generally elongated second panel member having opposite side edge portions connected to the first panel member to define a hollow between the first and second panel members. A filler is disposed within a portion of a cross-section of the hollow between the first and second panel members. This filler is provided on an inner surface of one of the first and second panel members and has an average compressive strength equal to or greater than 4 Pa and/or a maximum bending strength equal to or greater than 10 MPa.

Abstract: A structural module (hardware cassette) is provided suitable for use in the assembly of a vehicle door. The module includes a latch mounting member, a pair of door hinge assembly components (a lower door hinge component and an upper door hinge component) vertically spaced from one another when mounted in a vehicle, and tubes connecting the hinge components to the latch mounting member, one tube being connecting the upper hinge to the latch mounting member and extending substantially from the upper hinge component to the latch mounting member when mounted in the vehicle and a pair of laterally spaced tubes connecting the lower hinge component and the latch mounting member.
