Embodiment Construction

[0019] A motor vehicle 1 , exemplified by a sedan, has a body 2 , which is formed in the region shown by a roof 3 , a rear side panel 4 and a rear window 5 . In the exemplary embodiment, the rear window 5 is assigned to the luggage compartment lid 6 , the upper edge of which is hinged to the adjoining body 2 via hinges not shown. figure 1 The motor vehicle shown has a hatchback 7 , ie the rear is inclined at an angle of more than 30° relative to the horizontal.

[0020] In the region of the roof rear edge 8 , in the region of the upper edge of the luggage compartment lid 6 , a rear-side air guide 9 , commonly referred to as a roof air deflector, is arranged, wherein the upper inflow surface 10 of the air guide 9 Extending in the imaginary extension of the upper side 11 of the front roof ( figure 1 ). Due to the rear-side air guiding device 9 in the area of ​​the rear edge of the roof, the rear-side separation edge of the airflow passing through the roof 3 is displaced furthe...

Abstract

A rear air guiding device is disposed in a region of a roof rear edge on a tailgate provided with a rear window. An upper approach flow surface of the air guiding device forms an extension of the roofupper side mounted in front thereof, and the air guiding device protrudes over an upper border region of the rear window. In order to reduce the outlay on components and installation and also the weight of the air guiding device, it is provided that the latter is composed of a front part which is integrated in the tailgate and of a rear part which adjoins the front part such that their outer skins are flush and is connected to the front part.

Description

technical field [0001] The invention relates to a rear-side air guide for a motor vehicle, which is arranged in the region of the rear edge of the roof on a luggage compartment lid with a rear window, wherein the upper inflow surface of the air guide is on the upper side of the front roof Extending in the extension of the rear window, the deflector protrudes beyond the upper edge region of the rear window. Background technique [0002] For hatchback vehicles (such as the BMW X5), it is known to arrange a rear-side air deflector, commonly called a roof air deflector, in the region of the rear edge of the roof above the rear window, whereby the rear-side air deflector The airflow separation edge is displaced rearwards and thus reduces the dead water area behind the vehicle. [0003] A spoiler of this type consists of a plastic part having a large area and a considerable weight, which is attached to the outer side of the outer panel of the tailgate after the vehicle has been p...
