Patent number: 11312110Abstract: A vehicle pane has a first and a second pane element that are joined to one another surface-to-surface such that the vehicle pane has a first pane face, a second pane face, a third pane face, and a fourth pane face. The second pane face has a first printed region and the third or fourth pane face has a second printed region for forming a viewing region along the vehicle pane. The first and second printed region are each designed with at least a first, second, and third zone. At least one of the first and/or second zones is at least partially printed and the third zones are not printed. The second zones are implemented as a transition region between the first zone and the third zone such that an optical effect of the first printed region is compensated by an optical effect of the second printed region.Type: GrantFiled: November 21, 2018Date of Patent: April 26, 2022Assignee: SAINT-GOBAIN GLASS FRANCEInventor: Dirk Wohlfeil

Patent number: 10850477Abstract: A vehicle composite pane having an outer pane made of glass and an inner pane made of glass that are bonded to one another via a polymeric intermediate layer is presented. According to one aspect, the intermediate layer includes a first wedge inlay and a second wedge inlay that are made of different materials, each of the inlays being wedge-shaped and having a wedge face. According to another aspect, the wedge faces are positioned one atop the other so that, in the direction from a lower edge to an upper edge of the composite pane, the thickness of the first wedge inlay increases and the thickness of the second wedge inlay decreases. According to a further aspect, at least one of the wedge inlays has a refractive index that differs from the refractive index of the outer pane and of the inner pane.Type: GrantFiled: June 19, 2017Date of Patent: December 1, 2020Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Klaus Schmalbuch, Dirk Wohlfeil, Malte Linn, Martin Arndt, Christian Effertz

Patent number: 10703073Abstract: A vehicle composite pane with an integrated light sensor is disclosed. The vehicle composite pane includes an outer pane and an inner pane that are bonded to one another via a thermoplastic intermediate layer. A plurality of photodiodes situated on a circuit board are arranged between the outer pane and the inner pane. The photodiodes are surface-mounted device (SMD) components. The photodiodes are arranged on the circuit board as groups of parallel connected photodiodes. All groups of the parallel connected photodiodes are connected to a common electrical input and each group is connected to a separate electrical output.Type: GrantFiled: November 14, 2016Date of Patent: July 7, 2020Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Christian Effertz, Klaus Schmalbuch, Dirk Wohlfeil, Detlev Duerkop, Guido Schwinges, Michael Zeiss
