Abstract: A vehicle interior lining having very good sound absorbing properties and is air-permeable to air comprises an outside decorative layer, a barrier layer arranged on the rear side of the decorative layer, and a foamed layer which directly adjoins the barrier layer and is produced by back foaming. The barrier layer is formed from cellulose fleece and prevents the material used to form the foamed layer from seeping through to the decorative layer. The vehicle interior lining is air-permeable after the foamed layer is cured and can be used as, for example, a roof lining.

Abstract: The invention relates to a vehicle body panel part, particularly a vehicle roof panel, which has a very good surface quality. The vehicle body panel part includes an outer part forming at least a portion of an outer skin, a plastic inner layer formed by back foaming on a rear side of the outer part, and at least an elongated, tubular hollow body that is embedded in the plastic inner layer. The hollow body is completely enclosed and surrounded by the inner layer.

Abstract: A vehicle roof module includes an outer skin and a foamed backing on a rear side of the outer skin. At least one elongated hollow element is embedded in the foamed backing. The elongated hollow element acts as a support for add-on components and may also house signal transmission components, such as cables.

Abstract: A deformation element, in particular for use in motor vehicles, comprises a first base part and a second base part. The first base part includes at least one protrusion which tapers starting from the first base part The second base part includes at least one recess which tapers from a front side to a rear side thereof and is associated to the protrusion.

Abstract: A seal for the guide of an openable vehicle roof has an elastic sealing profile and a harder sealing strip that is mounted thereon and that is configured as a separate part. When the seal must be compressed, in order to make space for a connecting member between the longitudinal guide and the raised cover panel, only the sliding strip is contacted so that the sealing element is not subjected to any wear and tear.

Abstract: A vehicle interior lining having good sound absorbing properties and that is permeable to air is formed from an intermediate product comprising an inside decorative layer and a barrier layer made of open-cell foam. The barrier layer adjoins the rear side of the decorative layer. A foam backing is disposed on the rear side of the intermediate product is provided with a foam backing. The barrier layer prevents the foam backing material from penetrating through toward the decorative layer, eliminating the need for a barrier film and improving sound absorption. The interior lining can be used as a roof lining.

Abstract: A foaming die comprises a lower part and an upper part. A foaming cavity is formed between the lower part and the upper part, and a membrane is mounted on the inside of the foaming die at the inside of at least one of the lower part and the upper part. The membrane delimits the foaming cavity and transports gas to gas outlet openings during the foaming process. The invention is particularly suitable for forming vehicle body panel parts with a foamed backing.

Abstract: A vehicle roof having a roof frame and a roof module permanently and fixedly attached to the roof frame has a rigid safety element on the lower side of the roof module. The safety element engages the roof frame and holds the roof module on the roof frame in the event of a plastic deformation of the roof frame.

Abstract: A modular vehicle roof, in particular motor vehicle roof, is proposed which has a strong outer roof skin as its outer shell and an inner shell of foamed plastics connected firmly thereto, preferably foamed thereon, in the manner of the sandwich. A preferably transparent panel of glass or plastics, which allows light to reach the vehicle interior, is inserted into the vehicle roof and attached and sealed thereto in a particular way, approximately flush with the outer surface. The modular vehicle roof is simple and economic to produce, is light and has only a small structural height.

Abstract: A method of manufacturing a vehicle body part embeds an insert piece into a foamed layer of the body part by holding the insert piece in a foaming tool using a magnetic force. The magnetic force holds the insert piece into position, eliminating the need for any additional holding structures in the foaming tool. A body part made by this method has improved visual quality, particularly at a transition area between the insert piece and a decorative part.

Abstract: The roof module is formed from outer and inner polyurethane layers. The inner polyurethane layer has a first thickness, which is larger than a second thickness of the outer polyurethane layer. The inner layer is injection molded, and the outer layer is then molded to the inner layer. The inner polyurethane layer is molded with an embedded reinforcement material.
