Air deflector in a vehicle rear area

Abstract

The invention relates to an air guiding device in a vehicle rear area, comprising a tailgate (5) having a rear window (7) on the opposite side edges of which in the vehicle transverse direction (y) a side spoiler (11) is arranged, which can be adjusted between a retracted position and an extended position when an actuating force is applied. According to the invention, the actuating force is accompanied by a material deformation, in particular material bending, of the side spoiler (11), during which the side spoiler (11) can be adjusted while changing its shape.

Claims

[1] Air guiding device in a vehicle rear area, with a tailgate (5) which has a rear window (7), on the side edges of which, in the vehicle transverse direction (y), are arranged a side spoiler (11) which is adjustable between a retracted position and an extended position when an actuating force is applied, characterized by that the actuating force is accompanied by a material deformation, in particular material bending, of the side spoiler (11), in which the side spoiler (11) is adjustable while changing its shape. [2] Air guiding device according to claim 1, characterized by that the side spoiler (11) has on its visible side a deformable cover layer (13) which covers an actuator (39) for applying the actuating force in a manner protected from view. [3] Air guiding device according to claim 1 or 2, characterized byin that the deformable cover layer (13) is a shell-shaped hollow profile element which is elongated along a side spoiler longitudinal axis (L), with a side flank (21) on the outside of the vehicle in the vehicle transverse direction (y) and a side flank (23) on the inside of the vehicle, which converge at a trailing edge (25) which projects from the rear of the vehicle and extends along the side spoiler longitudinal axis (L). [4] Air guiding device according to claim 3, characterized bythat an apex angle (α) is spanned between the two side flanks (21, 23), and that when actuating force is applied, the actuator (39) varies the apex angle (α) between the side flanks (21, 23) so that, in particular in the extended position, the cover layer (13) is shaped into an acute-angled side spoiler shape in which the apex angle (α) between the side flanks (21, 23) is reduced, or in the retracted position the cover layer (13) is shaped into an obtuse-angled side spoiler shape in which the apex angle (α) between the side flanks (21, 23) is increased. [5] Air guiding device according to one of the preceding claims, characterized bythat the side spoiler (11) has a supporting part (17) which is connected at the edge to the outer surface of the rear window (7), and / or that the cover layer (13) together with the rear window (7) delimits an assembly space (34) in which the actuator (39) and / or the supporting part (17) are arranged in a way that is protected from view. [6] Air guiding device according to one of the preceding claims, characterized by that the actuator (39) has a tension / compression strut (33), the ends of which are connected directly or indirectly to the side flanks (21, 23) of the cover layer (13) in a way that transmits the actuating force, and that in particular the actuator (39) has an actuating drive (37) with which the tension / compression strut (33) can be adjusted in length. [7] Air guiding device according to one of claims 3 to 6, characterized byin that, in order to provide a defined material bend at the trailing edge (25), each of the side flanks (21, 23) of the cover layer (13) has a material reinforcement, in particular a reinforcement element (27) on the inside which is component-stiff compared to the cover layer material, and in particular the material reinforcements of the two side flanks (21, 23) at the trailing edge (25) are spaced apart by a clearance (29), so that in order to provide a defined bending axis (B), the cover layer region at the trailing edge (25) remains free of reinforcement. [8] Air guiding device according to one of claims 2 to 7, characterized by that the cover layer (13) is made of a partially transparent material, and that in the mounting space (34) of the side spoiler (11) at least one lighting element (19) is arranged, which can be controlled depending on the operating conditions of the vehicle. [9] Air guiding device according to one of claims 2 to 8, characterized bythat the actuator (39) is in electrical signal connection with an electronic control unit of the vehicle, by means of which the lighting element (19) and / or the actuator (39) can be controlled depending on operating states of the vehicle, and / or that in particular the side spoiler (11) can be adjusted between the retracted and extended positions depending on the vehicle speed, and / or that in particular in a parking situation when the tailgate (5) is opened the side spoiler (11) can be adjusted to its retracted position. [10] Vehicle with an air guiding device according to one of the preceding claims.
