As a result, a draft-free ventilation of the head of the person P is effected in an advantageous manner.

The personal air vents I in the instrument panel are not switched on or it is provided that the passenger vents I can not be activated in this driving mode.

In the first row of seats SR1 becomes the passenger compartment 10 in the second segment S2, the "directed vertical air supply with a large amount of air - climate zone c)" of at least one below the roof 110 arranged Dachausströmers D supplied. As a result, a directed ventilation of the face of the head of the person P is effected with a large amount of air in an advantageous manner.

In the first row of seats SR1 becomes the passenger compartment 10 in the third segment S3, the "non-directional vertical air supply with low air volume (draft-free) - climate zone d)" over at least one below the roof 110 arranged Dachausströmer D supplied. As a result, a draft-free ventilation of the legs of the person P is effected in an advantageous manner.

In the second row of seats SR2 becomes the passenger compartment 10 in the first segment S1, the "directed vertical air supply with a large amount of air - climate zone c)" of at least one below the roof 110 arranged Dachausströmers D supplied. As a result, a directed ventilation on the face of the head of the person P is effected in an advantageous manner.

In the second row of seats SR2 becomes the passenger compartment 10 in the second segment S2 a "non-directional vertical air supply with a small amount of air (draft-free) - climate zone d)" on the at least one below the roof 110 arranged Dachausströmer D provided to effect advantageously a draft-free ventilation of the head and the legs of a person P in the second row of seats SR2.

Finally, in the second row of seats SR2 in the third segment S3, for example, the "inactive ventilation - climate zone b)" of at least one below the roof 110 arranged Dachausströmers D set, whereby the back region of the person P on the second row of seats SR2 is free of draft.

The 3C shows a possible ventilation of the passenger compartment 10 , for example, intended for "fully automatic driving in night mode". The persons P are in the first and second rows of seats SR1, SR2 each facing forward in the -x direction.

The following setting is suggested or can be selected: row Seat segments climate zone SR1 11 . 12 S1 Climate zone d) SR1 11 . 12 S2 Climate zone d) SR1 11 . 12 S3 Climate zone d) SR2 21 . 22 S1 Climate zone d) SR2 21 . 22 S2 Climate zone d) SR2 21 . 22 S3 Climate zone d)

The 3D shows a freely programmable ventilation of the passenger compartment 110 , designed for all conceivable driving modes. In the embodiment according to the 3D the persons P take the positions according to 3B and associated description.

The following setting is suggested or can be selected: row Seat segment climate zone SR1 11 S1 Climate zone d) SR1 11 S2 Climate zone c) SR1 11 S3 Climate zone d) SR2 21 S1 Climate zone c) SR2 21 S2 Climate zone d) SR2 21 S3 Climate zone b)

It becomes clear that the left vehicle seats seen in the direction of travel -x-direction 11 . 21 the seat row SR1 and the seat row SR2 essentially the setting according to 3B and associated description, with the difference that the segments S1 to S3 are each freely programmable with respect to the selection climate zone a) to d) and / or with respect to the selection area of the segments S1 to S3.

For example, in the first row of seats SR1 is the segment S2 of the left seat 11 across from 3B formed enlarged, whereby the segment S3 of the seat 11 the first row of seats SR1 opposite the 3 is smaller.

The solution thus makes possible an individual adjustment of the air distribution and / or the air quantity, in particular via the change in the outflow area of the user-selected climatic zones a), b), c), d).

In the embodiment is over the seat 11 the first row of seats SR1 in the first segment S1, the "non-directional vertical air supply with low air flow (draft-free) - climate zone d)" of at least one below the roof 110 arranged Dachausströmers D compared to 3B increased. The "directed vertical air supply with large amount of air - climate zone c)" of at least one below the roof 110 arranged Dachausströmers D of the seat 11 of the second segment S2 of the first row of seats SR1 is displaced in the + x direction (counter to the direction of travel -x) and at the same time increased, so that the second segment S2 of the seat 11 the first row of seats S1 has an individually adapted outflow surface. The third segment S3 of the seat 11 the first row of seats SR1 with the climate zone d) is thereby reduced.

In the embodiment is also above the seat 21 the second row of seats SR2 in segment S1, the "directed vertical air supply with a large amount of air - climate zone c)" of at least one below the roof 110 arranged Dachausströmers D compared to 3B and description downsized.

At the same time, the "undirected vertical air supply into the passenger compartment 10 with low air flow (draft-free) - climatic zone d) "of at least one below the roof 110 arranged Dachausströmers D second segment S2 of the seat 21 the second row of seats SR2 compared to 3B shifted in the -x direction and enlarged, so that the second segment S2 of the seat 21 the second row of seats SR2 has a customized enlarged outflow area.

The third segment S3 of the seat 21 the second row of seats SR2 with the climatic zone b) is compared with in terms of the size of the outflow surface 3B essentially not changed.

The following setting is suggested or can be selected: row Seat segment climate zone SR1 12 S1 Climate zone b) SR1 12 S2 Climate zone c) SR1 12 S3 Climate zone b) SR2 22 S1 Climate zone b) SR2 22 S2 Climate zone d) SR2 22 S3 Climate zone b)

Also based on the seats 12 and 22 on the right side of the rows of seats SR1, SR2, the solution according to the invention is illustrated by the individual adjustment of the air distribution and / or the amount of air, in particular on the change in the outflow of each selected by the user climate zones a), b), c), d ) is feasible.

In the embodiment, above the seat 12 the first rows of seats SR1 in the right first segment S1, the climate zone b) set. In the second segment S2 of the first seat row SR1 of the seat 12 becomes the "directed vertical air supply into the passenger compartment 10 with large amount of air - climate zone c) "of at least one below the roof 110 arranged Dachausströmers D provided so that the face and legs of the person in the climate zone c) are ventilated over an enlarged outflow area. The outflow surface of the climate zone b) in the third segment S3 of the seat 12 the first row of seats SR1 decreases accordingly.

In the embodiment is also above the seat 22 the second row of seats SR2 in the first segment S1, the air supply to the passenger compartment 10 to the "inactive ventilation - climate zone b)" of at least one below the roof 110 arranged Dachausströmers D set, while the two segments S2 and S3 of the seat 22 the second row of seats SR2 on the "non-directional vertical air supply into the passenger compartment 10 with low air flow (draft-free) - climatic zone d) "of at least one below the roof 110 arranged Dachausströmers D are set so that in the illustrated seating position of the person P, the head and the back of the person P are ventilated draft-free with a small amount of air.

The detailed explanations make it clear that a roof vent system in the roof 110 of the motor vehicle 100 is created in which a freely selectable with respect to the discharge surface directed or non-directional (draft-free) flow of the person / s with low air flow (vertical climates a), d)) and a directed flow of the person / s with large amount of air (vertical climate zone c) can be combined.

The 4A to 4D (upper figures) illustrate once more in a plan view from above on the roof vents D in the direction of the passenger compartment 10 in that the outflow surface is variably adjustable. Preferred is over each seat 11 . 12 the first row of seats and above each seat 21 . 22 the second row of seats SR2 below the roof 110 a large Dachausströmer D attached.

It is clear that an adaptation of the outflow depending on the driving function or seat positions by means of the adjustable Dachausströmer D is possible.

The upper picture of the 4A illustrates as driving function the "manual driving". The persons P sit in the first and second rows of seats SR1, SR2 in the normal sitting position looking forward in the -x direction, as in 4A , bottom illustration based on the position of the backrests of the vehicle seat 11 . 12 . 21 . 22 is clarified. The Dachausströmer D of the first row of seats SR1 are open only to 1/3 of the total outflow of the respective Dachausströmers D. The Dachausströmer D the second row of seats SR2 are open to 2/3 of the total outflow of the respective Dachausströmers D.

The upper picture of the 4B illustrates as a driving function, the "fully automatic driving in day mode". The persons P sit in the first and second rows of seats SR1, SR2 analogous to the 2 opposite, as in the lower picture of the 4B based on the position of the backrests of the vehicle seats 11 . 12 . 21 . 22 of the 4B becomes clear. The Dachausströmer D of the first row of seats SR1 and the second row of seats SR2 are each open to 2/3 of the total outflow of the respective Dachausströmers D.

The upper picture of the 4C illustrates as a driving function, the "fully automatic driving in night mode" with the so-called individually adjustable sleep mode. The persons P are also sitting here in the first and second rows of seats SR1, SR2 analogous to the 2 opposite, as in the lower picture of the 4C based on the position of the backrests of the vehicle seats 11 . 12 . 21 . 22 of the 4C becomes clear. The Dachausströmer D the first row of seats SR1 and the second row of seats SR2 are each open to 3/3 of the total outflow of the respective Dachausströmers D, with the possibility that over each of the seats 11 . 12 . 21 . 22 individually at least one of the "vertical climate zone" a), b), c), d) is adjustable.

The upper picture of the 4D illustrates as a driving function, the "fully automatic driving in night mode" with the so-called automatic sleep mode. The persons P are also sitting here in the first and second rows of seats SR1, SR2 analogous to the 2 opposite, as in the lower picture of the 4D based on the position of the backrests of the vehicle seats 11 . 12 . 21 . 22 of the 4D becomes clear. The Dachausströmer D of the first row of seats SR1 and the second row of seats SR2 are each open to 3/3 of the total outflow of the respective Dachausströmers D, wherein one of the "vertical climates" a), b), c), d) is set automatically. How to the 3C is explained, for example, in all segments S1, S2, S3 of the seat rows SR1 and SR2 a "non-directional vertical air supply into the passenger compartment with low air flow (draft-free) - climate zone d)" on the below the roof 110 arranged roof outlets D set, creating a quieter and draft-free night operation on all seats 11 . 12 . 21 . 22 is effected uniformly.

The interactions of the seats 11 . 12 . 21 . 22 seated persons P with the Dachausströmersystem done for example via a gesture and / or touch function.

A ride-on activates, for example, by a gesture or a touch near or on the surface of the roof outlet D a certain outflow area of the Dachausströmers D, which is activated by a gesture or a touch accordingly.

To realize the gesture function, for example, at least one sensor detects a signal deviation in an electrode field close to a control surface in the actual surface of the roof outlet D.

To realize the touch function, for example, capacitive touch sensors are provided in an operating surface of the roof outlet D.

In another embodiment, the activation via a touch screen, so that the Dachausströmer D each seat 11 . 12 . 21 . 22 via an illustration of their associated active surface of the roof vents D in the roof 110 and additional mapping of the seating position of the driver on the seats 11 . 12 . 21 . 22 via adjusting elements in the roof vents D with respect to outflow surface and / or with regard to the desired climatic zones a), b), c), d) can be adjusted.

In another embodiment, it is proposed to provide an automatic body position detection, which always sets the Roof outlet system according to predetermined preferences of the seated person.

A preference could be, for example, that no directed vertical air supply with a large amount of air - climate zone c) "for ventilation of the rear / top head is desired. By the body position detection occurs, for example, in a repositioning of the driver inside the passenger compartment 10 to an automatic preference-dependent conversion of Dachausströmer D Dachausströmersystems on the example mentioned climate zone c).

Furthermore, the possible and / or successful interactions or the set state of the roof vents D can be highlighted via graphical elements and / or via lighting, wherein the following characteristics are proposed.

Illuminated linear enclosure of the active discharge area of roof outlets D.

Flat illumination of the active outflow area of the roof outlets D. For example, a backlighting of the active outflow area by means of LED technology is proposed. In other words, the cladding elements from which air actively flows out, so that the acting person P perceives on the basis of the lighting, whether the desired setting has been made.

In addition, it is proposed that the set outflow temperature of the air flowing out of the roof vents D be clarified via an associated color of the backlighting of the active area by means of LED technology.

In addition, an indication of the ventilation intensity over the brightness is proposed. In other words, the set amount of air or the outflowing amount of air flowing out of the Dachausströmern D air is illustrated by an associated brightness of the backlighting of the active Ausströmbereichs by LED technology.

It is envisaged that the interactive marking for energy saving Dachausströmersystems is activated for example by the touch or gesture and is then activated only during and only for a short time after the operation.

In a combination of the ventilation system comprising the roof-side Ausströmersystem (Dachausströmersystem) on the Dachausströmer D with the bottom-side Ausströmersystem on Bodenausströmer B (Bodenausströmersystem) is provided that on the Dachausströmer D primarily cold air into the passenger compartment 10 is blown.

The 4A to 4D (bottom pictures) clarify that the outflow surfaces of the roof vents D above each seat 11 . 12 the first row of seats and above each seat 21 . 22 the second row SR2 with floor vents B in the floor 120 of the motor vehicle 100 can be combined.

It is understood that on the roof vents D not only cold air, but also tempered air in the passenger compartment 10 can be blown.

If, for example, the roof vents D primarily cold air in the passenger compartment 10 blown, so the Ausströmersystem in the roof 110 with bottom vents B in the ground 120 of the motor vehicle 100 combined. The floor vents B are in the lower figures of the 4A to 4D each below the seats 11 . 12 . 21 . 22 arranged in the rows of seats SR1 and SR2 and marked for clarity with circles.

The floor vents B are under the seats 11 . 12 . 21 . 22 installed, which preferably evenly to all sides or in and against the direction of air can flow.

To clarify the seating positions of the persons are in the 4A to 4D , as already explained in the lower figures, respectively, the backrests of the seats 11 . 12 . 21 . 22 shown.

In 8th is shown below the top in 9 not shown lid D22 a lighting system D28 is installed, as illustrated by the arrows.

The fact that the roller blinds D23, 24 are essentially opaque to light causes the remaining air-permeable outflow surface D27 to be illuminated in the lower cover D22 of the housing provided with a passage opening, so that the active discharge surface D27 is illuminated from below in a recognizable manner.

As already explained in the first embodiment, the color and / or the brightness of the light system D28 can change accordingly depending on the temperature and / or the volume flow amount.

The 10 shows the bottom with the air-permeable lid D22, wherein the air-permeable lid D22 is formed for example of a perforated plastic.

According to the invention, the air-permeable cover D22 with a likewise air-permeable facing element D22-A ( 11 ) to give the second Dachausströmer D2 an appealing design.

Finally, from the simplified layered structure of the second Dachausströmers D2 in 11 becomes clear, the second Dachausströmer D2 thus comprises the upper airtight lid D21, under which preferably the light system D28 with LED's or OLED's is arranged.

Below this light system D28 are located in the housing, the two blinds D23, D24, which are movably disposed between the side surfaces of the housing. The underside of the housing is closed by the air-permeable cover D22, wherein it is provided, for example, to arrange capacitive sensors D29 between the air-permeable veneer element D22-A and the air-permeable cover D22, so that by approaching or touching an operator's hand on the air-permeable veneer Control of the two actuators of the blinds D23, D24 together or independently in the desired / n direction / s is possible. The capacitive approach or contact in the longitudinal direction +/- x-direction of the second Dachausströmers D2, the opening and closing and / or the displacement of the active Ausströmfläche D27 can be influenced segment-like.

The 12 shows in addition the two blinds D23, D24 in the housing of the second Dachausströmers D2 with the indicated light cone in the region of the actively connected (open) Ausströmfläche D27.

A third embodiment of a third Dachausströmers D3 show the 13 and 14 , which are also explained in a synopsis.

The 13 and 14 each show a section through the third Dachausströmer D3 in the longitudinal direction of Dachausströmers D3.

For example, the air flows according to the 13 and 14 from back to front in the -x direction, as illustrated by the arrows, in the third Dachausströmer D3 a.

The third Dachausströmer D3 also includes a housing with an airtight lid D31 on the top and an air-permeable perforated lid D32 on the bottom. An air-impermeable element, in particular a plate D35, which divides the roof vent D3 into an upper inflow area D33-1 and into a lower inflow area D33-2 is provided in the side parts of the housing in the flow direction -x.

In the side parts are also each arranged with their axes of rotation, which are arranged transversely (in the y direction) to the incoming air, an interchangeable valve D33 and a butterfly valve D34.

Below the plate D35, which subdivides the housing into the upper and lower inflow regions D33-1, D33-2, a light system D38 is arranged in analogy to the previous embodiment, which is in color and brightness depending on which active outflow surface D37 is connected generates different colors or brightnesses analogously to a certain temperature or to a certain volume, whereby the already described signal effect is effected in the user.

13 shows the position of the changeover damper D33 and the shut-off damper D34 for activating the front entrance-side air-permeable discharge face D37 of the lower lid D32. The change-over flap D33 closes the upper inflow region D33-1, wherein the shut-off flap D34 closes the rear region of the air-permeable lower cover in its illustrated closed position.

The butterfly valve D34 is mounted relative to the housing in airtightly arranged guide rails D39 in the likewise airtight side parts of the housing and is guided in the flow direction -x displaceable in +/- x-direction and rotatable about their axes of rotation transversely to the +/- x-direction, so the opening and closing and / or the displacement of the active discharge surface D37 can take place segment-like.

The 14 shows the case in which the rear portion of the through the air-permeable lower cover D32 is connected in an active Ausströmfläche D37. The flap D33 closes the lower inlet area D33-2 and the butterfly valve D34 remains facing 13 in the same position, so the Air now flows over the upper inflow D33-1 and an open at the rear of the housing overflow D33-3 in the rear region of the lower air-permeable lid D32.

In the two figures is still indicated that the butterfly valve D34 can take by turning about its axis of rotation and a horizontal position which is transverse to the middle plate D35. In this case, the entire air-permeable outflow surface D37 of the air-permeable lid D32 is actively switched, since the inflowing air regardless of the position of the flap D33 over the lower area ( 13 ) or the upper area ( 14 ) can flow out over the entire outflow surface of the air-permeable lower lid D32. In this case, the entire D38 lighting system is switched on because the entire discharge area D37 is active.

The 15 to 17 show in a further summary of a fourth embodiment of a fourth Dachausströmers D4. The 15 shows a bottom of the Dachausströmers D4 with an air-permeable perforated lower cover D42. The 16 shows a top of the roof vent D4 and the 17 shows a perspective section through the Dachausströmer D4.

According to the 15 to 17 For example, if the air flows from the back to the front in the -x direction, as illustrated by the arrows, it enters the roof vent D4.

The 15 shows in particular the bottom with the perforated structure of the air-permeable lower cover D42 of the housing of the Dachausströmers D4.

Arranged behind the illustrated fan flange are air guide elements D43 which segment the fourth roof vent D4 in the flow direction -x direction.

Basically, it is conceivable that a segmentation via air guide D43 is also possible transversely to the flow direction in the y-direction, as it is in connection with the 3A to 3D has been described.

By manual or actuator adjustment of the air guide elements D43, the sections or the segments of the fourth Dachausströmers D4 formed thereby can be supplied with different amounts of air.

It is also planned how 16 illustrates that by at least one adjustment D48, the inclination of the upper air-impermeable lid D41 with respect to the lower air-permeable lid D42 is adjustable.

As a result, the cross-section of the housing in the flow direction can be tapered, so that viewed in the flow direction at the end of the fourth Dachausströmers D4 is a smaller cross-section than in the inlet region of the fourth Dachausströmers D4, thereby ensuring a uniform air outlet in the actively connected Ausströmfläche D47 of the fourth Dachausströmers D4 is.

It is preferably provided in the longitudinal direction +/- x-direction of the fourth Dachausströmers D4 a displaceably mounted with a rotational axis transverse to the flow direction rotatable control valve D44 ( 17 ).

The rotatable control valve D44 is mounted relative to the housing in airtightly arranged guide rails D49 in the side parts D45, D46 of the housing and is slidably guided in the +/- x direction and rotatable about their axes of rotation transversely to the +/- x direction, so that the Opening and closing and / or moving the active Ausströmfläche D47 can be made segment-like.

In 17 is illustrated by the arrows shown that the control valve D44 is slidable in the +/- x-direction and rotatable about the y-axis axis of rotation, so that by positioning the control valve D44, the active air outlet or the air outlet amount in the respective active area is adjustable in front of and behind the control flap D44.

In 17 the air-permeable region of the lower lid D41 is shown at the top, so that the active air outlet surface with the control flap D44 closed is in this representation in a front active Ausströmfläche D47 on the top, as illustrated by the arrows shown.
