Abstract

The invention relates to a decorative part ( 11 ) for a motor vehicle and a method for the production thereof, having a carrier part ( 18 ) and having a covering part ( 12 ) made of a single-pane safety glass, which are connected to each other, wherein a bonding agent layer ( 17 ) is applied over the entire surface on a fixing side ( 16 ) of the covering part ( 12 ) opposite the visible side ( 14 ) of the decorative part ( 12 ), and a layer made of a thermoplastic elastomer ( 26 ) is provided over the entire surface on the bonding agent layer ( 17 ), by means of which the carrier part ( 18 ) is fixedly connected to the covering part ( 12 ), wherein at least one sealing lip ( 34, 51 ) is moulded on the TPE layer ( 26 ).
