Coupling assembly with composite sheet and flat ribbon cable

The invention relates to a coupling assembly (1) comprising:-a composite sheet (2) consisting of a first sheet (3) and a second sheet (4), which are connected to one another in a planar manner via a thermoplastic intermediate layer (9); -an electrical functional element (10) between the two sheets (3, 4); a flat ribbon cable (11) having an electrical conductor track (12), the flat ribbon cable (11) having a first coupling region (6) at a first end (5) and a second coupling region (8) at a second end (7), the first coupling region (6) being arranged between the two sheets (3, 4), and the second coupling region (8) being arranged between the two sheets (3, 4). The electrical functional element (10) has a first connection region (6), and the second connection region (8) is drawn from the composite sheet (2) between the two sheets (3, 4), and wherein the electrical conductor track (12) electrically contacts the electrical functional element (10) in the first connection region (6); -one or more electrical connecto
