The present invention relates to a transverse-member motor-vehicle module for receiving the instrument panel and reinforcing the bodywork for the direct connection of the two A-pillars of a motor vehicle, composed of a transverse member with a steering-column retainer, where the transverse-member module, i.e. not only the transverse member but also the steering-column retainer, are manufactured using a metal-plastic-composite design (hybrid technology), and these are composed of at least one main body and of at least one first thermoplastic part and one second thermoplastic part, where these have been securely bonded via injection molding firstly to the main body and simultaneously the various plastics parts have been bonded to one another, where the two plastics parts are composed of different plastics materials and these are injected in the bi-injection molding process, where they fuse with one another when they encounter one another.
A transverse-member motor-vehicle module for receiving an instrument panel of a motor vehicle comprising
A process for influencing the intrinsic vibration behavior of an instrument-panel support of a motor vehicle in installed condition to give a first-mode natural frequency >36 Hz, comprising the steps of
A method of using a transverse-member module for attachment under an instrument panel of a motor vehicle, comprising an at least partially plastic component A and plastic component B-surrounded tubular main body (1), composed of metal or high-strength plastics material, and a moulded sheet-metal profile functioning as steering-column retainer (2) and designed and placed in such a way that it, in the composite with moulded-on plastic, firstly gives a stiff connection between steering column and front wall and secondly has firm connection to the main body (1) by way of a structure consisting entirely of plastic, where, by way of the use of at least two different plastic component A and plastic component B moreover link elements (6, 7) for functional elements are moulded on, and the various plastics materials (A or B) permit secure bonding of the various plastics parts to one another, in that the at least partially plastic component A and plastic component B fuse with one another when they encounter one another in the bi-injection moulding process, for influencing the intrinsic vibration behavior of the instrument-panel support in the installed condition to give a first-mode natural frequency >36 Hz.
