Abstract: A process for laminating a material layer to a support including: providing the support, applying the material layer to the support, a heat-activatable adhesive being applied to s side of the material layer facing the dimensionally stable support and/or to the side of the dimensionally stable support facing the material layer, pressing the flexible material layer and the dimensionally stable support together by means of a lower dimensionally stable mold half and an upper dimensionally stable mold half, irradiating the mold halves, the support and the material layer with electromagnetic radiation, in particular with microwave radiation, high-frequency radiation or induction radiation, whereby the adhesive is activated directly or indirectly.

Abstract: Embodiments disclose a trim part comprising an airbag system for the interior of a motor vehicle. The trim part comprises a carrier, on which an airbag module is disposed. A joint is formed at least in sections between the carrier and the airbag module. A primary connecting element, which includes an adhesive, is disposed within the joint so that the primary connecting element is non-detachably connected both to the carrier and the airbag module. The trim part further comprises at least one secondary connecting element for temporarily fixing the airbag module to the carrier before the non-detachable connection between the carrier and the airbag module is created by the primary connecting element. Embodiments further disclose a method for the production of the trim part.

Abstract: A vehicle interior component fabricated using a hot melt adhesive having two base polymers with different melting points, a higher melting point and a lower melting point, for bonding the surfaces of at least two layers of the vehicle interior component. The hot melt adhesive is applied to one of the layers in an activated state at a temperature equal to or greater than the higher melting point and closely bonds with the layer when the adhesive cools to a temperature below the higher melting point. The bond between the two layers is effected at a lower temperature corresponding to the lower melting point to enable removal of the component layers from a mold while still in a warm state.
