  • Patent number: 11014497
    Abstract: A component (1) for a vehicle having a visible side (11) comprises a first light guide (2), which comprises a light coupling-in surface (25) and a plurality of first light deflection elements (211, 212, 213, 214, 215), wherein light can be coupled into the first light guide (2) through the light coupling-in surface (25), and a plurality of diffuser elements (311, 312, 313, 314, 315) which are designed to scatter light diffusely. The first light deflection elements (211, 212, 213, 214, 215) are each designed to deflect the light coupled into the first light guide (2) by a deflection angle directed in the direction of the diffuser elements (311, 312, 313, 314, 315) so that the diffuser elements (311, 312, 313, 314, 315) scatter said directed light diffusely in the direction of the visible side (11).

  • Patent number: 10894879
    Abstract: A thermoplastic mixture is described that includes at least one impact-resistant polypropylene copolymer and at least one ethylene-1-octene copolymer. The weight ratio of impact-resistant polypropylene copolymer to ethylene-1-octene copolymer can be in the range of 35:65 to 65:35. The thermoplastic mixture has a high melting point and excellent flexibility. The mixture is suitable in particular for roof membranes and waterproofing membranes.

  • Patent number: 10759332
    Abstract: A component (1) is disclosed. The component (1) comprises at least one flat decorative element (2) having a visible side (3) and a back side (4), at least one layer (5, 5) having a front side (6) and a back side (7), which layer is arranged on the back side (4) of the flat decorative element (2), wherein the front side (6) faces the back side (4) of the flat decorative element (2), at least one housing (8) having an inner side (9) and an outer side (10), wherein the inner side (9) faces the back side (7) of the layer (5), wherein the housing (8) is made of a material which has a hardness that is different from the hardness of a material of which the layer (5, 5?) is made, and wherein the housing (8) engages in at least one recess (26) arranged in the layer (5, 5?) and/or the layer (5, 5?) engages in at least one recess arranged in the housing (8).
