Abstract

Disclosed is a component (1), particularly a crossbeam that is to be disposed between the A-shaped columns of a motor vehicle. Said component (1) comprises an essentially tubular or other elongate metallic basic member (1) to which a plastic (7) channel (2), especially a ventilation channel, is connected at least in part within the profile of said basic member (1), and a joining part (4) that is mechanically connected to the basic member (1) or a part rigidly connected thereto and is used for fixing another component. Said joining part (4) forms a material bond with the basic member (1) or a part rigidly connected thereto at a joining point (5), thus creating an intermediate area (12) so as to reduce heat transfer between the joining part (4) and the plastic (7) of the channel (2) and / or drain away a gas produced during the joining process.

Description

technical field

[0001] The present invention relates to a component, in particular a crossbeam arranged between the A-pillars of a motor vehicle, comprising a metal body substantially in the shape of a tube or consisting of an elongated shell open in outline, and at least one A plastic pipe, such as a ventilation pipe, partly surrounded by the contour of the body and mechanically connected to the body. Such a component is disclosed, for example, in DE 10064522 A1. Background technique

[0002] In a car, the cross member that connects the A-pillars doubles as an air duct, which saves weight and / or space. Covering the beam with plastic both increases its stability and reduces the chance of condensation of moisture contained in the air that is conditioned to be sent to the interior of the car. The connection points for other components such as the steering column or the airbags are arranged on the cross member. Such connection points are usually realized by connectors welded...

Embodiment Construction

[0033] FIG. 1 shows, in cross-section, a metal beam 1 with a known operating principle, which forms the body of a component according to the invention, which will be described in more detail below. The crossbeam 1 , also referred to as the dashboard support, is arranged as a support part of the body structure between the A-pillars of the vehicle and forms a mechanical connection with other components, such as the airbag housing.

[0034] The same principle of operation is known, for example, in DE 10064522 A1, according to the arrangement of FIG. 2 , with a cross member 1 having a circular cross-section duct or vent pipe 2 which is produced from plastic by injection moulding. Ventilation ducts 2 , which at least slightly increase the stability of the cross member 1 , extend along the cross member 1 , so that the supply air is distributed in the transverse direction of the vehicle.
