  • Patent number: 11485060
    Abstract: A method for producing a three-dimensionally shaped trim part of a motor vehicle, which has a visible side and a mounting side. A flowable material is injected with pressure into a chamber of an injection molding tool, which has at least two mold shells, which, when assembled, form the chamber with a negative mold of the trim part, wherein at least one first of the mold shells forms the visible side and at least one second of the mold shells forms the mounting side of the trim part. The material is hardened in the chamber. A gas pressure is generated that acts in a planar manner between the second mold shell and the material during the hardening. The hardened material is removed as a trim part from the chamber of the injection molding tool.

  • Publication number: 20220063370
    Abstract: An air duct device for a vehicle, in particular a motor vehicle, with a tubular air duct having an outer wall that is closed in cross-section, and with at least one elastically deformable latch associated with the air duct. Provision is made that the air duct is designed in at least two parts in cross-section and for this purpose has a first duct element and a second duct element, which are held against one another in a sealing manner by the at least one latch such that together they form the closed outer wall of the air duct.

  • Patent number: 10596738
    Abstract: A method for producing a component assembly for a motor vehicle, wherein the component assembly has a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the at least one functional component is injection-molded to the base body during the production of the component assembly and the component assembly is produced using a gas external pressure process. A component assembly for a motor vehicle is also provided, having a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the base body is produced as an integral injection-molded part together with the at least one functional component using an external gas pressure process. Also, a motor vehicle having a component assembly is provided.
