Embodiment Construction

[0018] exist Figure 1a and 1b In the schematic sectional view, a body component in the form of a door pillar 10 , for example a B-pillar, is shown. Figure 1a The doorpost 10 is shown in an undeformed state, as will also be explained in detail, in Figure 1b The door pillar 10 is shown after a force application caused by an accident, for example due to a side impact of a car.

[0019] The door pillar 10 here comprises a first outer individual component 12 and an inner second individual component 14 . In other words, the individual component 12 faces mainly towards the outside of the motor vehicle, and the individual component 14 faces towards the passenger compartment of the motor vehicle, not otherwise shown.

[0020] Depend on Figure 1a It can be seen that the first individual component 12 is substantially U-shaped and comprises two free arms 16 , 18 which are integrally connected to each other by a connecting arm 20 . The outer individual component 12 can here be produc...

Abstract

The invention relates to a chassis component for a motor vehicle comprising at least one first and a second individual component (12, 14) to form a composite component (10) having a plurality of hollow chambers, wherein the first individual component (12) has increased ductility for absorbing impact energy caused by an accident and the second individual component (142) has increased rigidity relative thereto.

Description

technical field [0001] The invention relates to a body component for a motor vehicle of the type specified in the preamble of claim 1 . Background technique [0002] Such a body component is known from GB 1 246 995, which consists of a plurality of individual components. Furthermore, the body component here comprises two metal shells which are joined to form an inner load-bearing area of ​​the body component. Furthermore, the body component formed as a side sill includes an outer sill trim made of plastic. Overall, this results in a composite component with a plurality of cavities, however, the rocker trim made of plastic does not contribute to the stiffening of the bodywork or to the absorption capacity in the event of a crash. Contents of the invention [0003] It is therefore the object of the present invention to provide a body component of the above-mentioned type which has, inter alia, improved crash and stiffness properties. [0004] This object is solved accordi...
