Embodiment Construction

[0018] First refer to figure 1 . The body component according to the invention, which is shown in a very simplified schematic form in longitudinal section in the drawing, relates to a door of a motor vehicle. The automobile door comprises a door shell cladding plate 13 and a support beam 10, and the support beam 10 is a side anti-collision beam deviated in the transverse direction of the automobile door. Between the strut 10 and the door shell cladding is provided a material 11 which is initially installed in an expandable form and can expand in the space between the strut 10 and the door shell 13 when heated. The material 11 in this embodiment is a foam material which preferably has good sound-insulating properties. These expandable materials 11 expand when heated, preferably at a temperature above about 200° C., and form a connection between the door shell cladding 13 and the stay beam.

[0019] according to figure 2 Shown is an enlarged detail view that reproduces the ...

Abstract

Bodywork component comprising at least one outer sheet metal, at least one reinforcement support and one foamed material disposed in-between the outer sheet metal and the reinforcement support, wherein the foamed material is a blown material (11) that is initially placed in blowable form and then blown by feeding heat into the space (12) between the reinforcement support (10) and the outer sheet metal (13). The bodywork component can be produced by initially placing an expandable material (11) in the form of a foamed material and expanding said expandable material (11) by feeding heat into the space (12) in-between the reinforcement support (10) and the outer sheet metal (13), thereby producing a connection between the reinforcement support (10) and the outer sheet metal (13).

Description

technical field [0001] The invention relates to a body component comprising at least one skin cladding, at least one strut and a foam material arranged between the skin cladding and the strut, and to a method for producing such a body component. Background technique [0002] Body components of the type described above are known in the prior art. For example, DE 24 14 114 A1 describes a body component, for example as a motor vehicle door, which has a skin cladding to which braces are fastened. This document relates to a cross member with an opening towards the skin cladding, which is used for lateral reinforcement of the vehicle door. This cross member, which is open relative to the door skin cladding, forms the interior space of the door skin cladding, which is filled with plastic. As such plastic, a foam such as polyurethane foam can be used. However, the volume of this foam material cannot be changed in a short time and is not changed during the production process of th...
