A disadvantageous effect of the solar protection devices mounted today is that they can affect the ventilation or air conditioning of the vehicle interior, depending on the installation location not insignificant.

The invention is accordingly an object of the invention to provide a Fahr ^¬ convincing, in which a sun protection device mounted therein for the air conditioning of the vehicle is not or at least less disturbing than in previously known vehicles.

This object is achieved by a vehicle with the features according to claim 1. Advantageous Substituted ^¬ staltungen of the vehicle according to the invention are specified in subclaims.

Thereafter, the invention provides that the sun protection device is mounted on the vehicle ceiling to form an air-permeable gap and the sun protection device has an adjustable air guide element, which influences the air flow through the gap position-dependent. A significant advantage of the vehicle according to the invention is the fact that a disturbing influence of the sun protection device on the air flow within the vehicle can be minimized by adjusting or optimally adjusting the inventive adjustable air guide element of the sun protection device according to the air technical requirements of the vehicle , The invention is based on the Gedan ^¬ ke, initially provide a gap between the vehicle roof and sunshade device during installation of the sunshade to allow air flow in the ceiling area, and - to optimize the air flow - vehicle-specific perform a subsequent adjustment of the Luftleit ^¬ elements. So it is possible, in other words, to mount the solar protection device in the vehicle first and only thereafter the vehicle individually to improve by adjusting the air guide element ^¬ airflow.

The sun protection device is preferably attached to the vehicle ceiling horizontally to form a horizontal gap; the longitudinal axis of the air guide is ^{vorzugswei ¬} se horizontally.

The air guiding element is preferably adjustable in such a way that, depending on the position, it more or less closes the gap and / or can deflect the air flow more or less.

With a view to an optimal influencing of the air flow in ^¬ within the vehicle, it is considered advantageous if the adjustable air guide element is pivotally supported on two - preferably in the horizontal direction - spaced retaining elements of the sun protection device and can take different swivel angle to the vehicle roof, depending on Angular position of the gap more or less closed and / or the air flow is deflected more or less.

The sun protection device 40 can be adjusted by the band 50 being unwound more or less from the shaft 60 along the direction of the arrow P.

In addition, FIG. 1 shows a ventilation ^opening 70, through which an air flow L is blown into the vehicle interior 11 of the rail vehicle 10. The air flow L extends along the windshield 25 upwards in the direction of the vehicle ceiling 12 of the rail vehicle 10, where it is deflected Lum in a substantially horizontal air flow.

In order to allow the airflow L to pass through the sunshade device 40 even when the belt 50 is unwound along the arrow direction P, the sunshade device 40 is mounted to the vehicle ceiling 12 to form a gap SP. For attachment of the sun protection device 40 on the vehicle ceiling 12 serve fasteners, one of which is shown in the figure 1 and there marked with the Bezugszei ^¬ chen 30. FIG. 2 shows the sun protection device 40 according to FIG. 1 again in greater detail. It can be seen Befestigungsele ^¬ ment 30, with which the sun protection device 40 is mounted on the vehicle ceiling 12. It can be seen that the fastening element 30 enables the formation of the gap SP, so that the air flow L between the housing 100 of the sunshade device 40 and the vehicle ceiling 12 can pass the sunshade device 40. As can be seen with reference to Figures 1 and 2, the air flow L is not negligible influenced by the sun protection device 40, so that with a view to optimal Kli ^¬ matization of the vehicle interior 11 of the rail vehicle 10 an optimal air flow between the housing 100 of the sun protection device 40 and the vehicle ceiling 12 is desirable.

3 shows an embodiment of a sun ^¬ protection device 40, wherein the housing top side 110 of the housing 100 is provided with an opening slot 120, an air guide element extends through the located 130 from the housing 100 out to the outside. The position of the Luftleitele ^¬ ment 130 is in the embodiment according to Figure 3 ver ^¬ be changed, so that this voltage slit more or less far from the Öff- protrude 120 and thus the gap SP between the vehicle ceiling 12 and the housing 100 (see FIGS. 1 and 2) can reduce more or less. By adjusting the air guiding element 130, it is thus possible to more or less influence the air flow L which passes through the region between the vehicle ceiling 12 and the housing 100 (see FIGS. 1 and 2) or with a view to an optimal one Climatization ^¬ tion of the vehicle interior 11 to adjust.

In order to allow an adjustment of the air guide 130 from the outside even after assembly of the sun protection device 40, the air guide 130 is mounted in the area of stirnseiti ^¬ gen housing walls 140 and 150 of the housing 100th The type of attachment of the air guide element 130 to the frontal The housing walls 140 and 150 will be explained in more detail below in connection with FIGS. 4 and 5.

In the sun protection device 40 according to Figure 3 is, for example, a roller blind, with a

wound up band 50 is provided, as it is in the embodiment without air guide element according to Figures 1 and

2 is present. The embodiment of the sun protection device 40 with a coilable belt 50 is indeed advantageous JE but it may alternatively be in the sun protection device 40 may also be a Roman blind, in which a band folded in particular ^¬ sondere zig-zag folded, is or a blind han ^¬ spindles. FIG. 4 shows the sun protection device 40 according to FIG

3 from the side. One recognizes the end-side housing wall 140, on which the air-guiding element 130 is displaceable and

is pivotally mounted. For attachment of the Luftleitele ^¬ ment 130 this is preferably equipped with a screw or a nem bolt, or form a pivot axis 200 about which the air guide 130 along the arrow direction of the double arrow SA can be pivoted.

In addition to a pivoting of the air guide element 130 about the pivot axis 200, it is possible to protrude the air guide 130 more or less far out of the housing 100 by the pivot axis 200 (or the mentioned screw or said bolt) along the direction of arrow P and moved the air guide element 130 is pushed out of the opening slot 120. In order to allow the displacement of the pivot axis 200 along the direction of the arrow P is in the

Housing wall 140 a slot 141 is provided which extends in the direction of the fastener 30 and in the direction of the vehicle ceiling 12. In the opposite housing wall 150, a corresponding slot is provided, which is hidden in the figure 4, however. The located in the housing, ie inner portion of the air guide element 130 is indicated in Figure 4 by reference numeral 131; the outside of the housing located, so outer portion of the air guide element 130 is marked in the figure 4 with the reference numeral 132.
