  • Patent number: 9096279
    Abstract: A rear region of a vehicle has an air-guiding device (10) with a mounting element (11) for the air-guiding device on the vehicle, and with at least one air-guiding element (13) that is shiftable between a retracted inoperative position and an extended operating position. A gap (14) is formed between the air-guiding element (13) and the mounting element (11) when the air guiding device (10) is in the extended operating position. However, the gap (14) can be closed via a closure device (15). The closure device (15) has a multi-layered, flexible sheetlike structure (16) with at least one front outer, flexible layer (17) and a rear outer, flexible layer (18). In the extended operating position, the front outer layer (17) can be stretched with the aid of a stiff clamping element (19) and the rear outer layer (19) can be stretched with the aid of a flexible clamping element (20).
