• Zum voll automatischen Einrichten der Liegestätte wird zuerst eine Unterschenkelstütze 5;I aus ihrer Stand-By-Position 5;I (vergleiche 1-1 zu 1-2) in einen über ein gedachten horizontalen Ebene liegenden Winkelgrad (Drehachse liegt quer zur Fahrtrichtung x) gemäß der Position 5;II* in eine sogenannte Vor-Liegeposition 5;II* gebracht. Infolge dessen liegen die Füße der Person P in vertikaler Richtung gesehen zunächst oberhalb des Niveaus der eine horizontale Ebene bildenden Ottomane 6 (vergleiche 1-2 und 1-3) in der Vor-Liegeposition 5;II*.

It is preferred (compare 1-1 to 1-5 ) proceeded as follows:

• To fully automatically set up the bed, a lower leg support is used first 5; I from their stand-by position 5; I (compare 1-1 to 1-2 ) in an angular degree above an imaginary horizontal plane (axis of rotation is transverse to the direction of travel x) according to the position 5; II * in a so-called pre-lying position 5; II * brought. As a result, the person's feet lie P seen in the vertical direction, first above the level of the ottoman forming a horizontal plane 6 (compare 1-2 and 1-3 ) in the pre-lying position 5; II *.

After that, the entire vehicle seat automatically F without a collision of the person's feet P with the ottoman 6 and without further changing the position of the other vehicle seat components (cf. 1-2 to 1-3 ) forward in the -x direction (cf. 3rd and 4th ) according to the arrow X moved so that the front edge of the lower leg support 5 seen in x direction in Essentially with the back edge of an ottoman 6 completes. Alternatively, the ottoman 6 also from a starting position (not shown) towards the occupant P be moved or the ottoman 6 folds up from a vertical y-side position (on the side of a center console or a vehicle door or an outer wall of the vehicle) into a horizontal user position so that it changes the position according to the 1 to 5 occupies. Then the person's feet are P (in each of the alternative solutions discussed) in a position above the ottoman 6 (compare 1-3 ) in which the person's feet P but are not yet filed.

In the next step, the seat of the seat part 1 including the calf pad on the lower leg support 5 in a horizontal position in the so-called final lying position 5; II brought. This will automatically put your feet on the ottoman 6 filed (compare positions in the 1-3 to 1-4).

Finally forms the seat part 1 who have favourited Leg Support 5 and the ottoman 6 (compare 1-4 and 1-5 ) a horizontal plane.

Finally or simultaneously with the lowering of the lower leg support 5 about the pivot axis SWA5 will also be the backrest 5 from the sitting position 5; I. or the relax position 5; I / II in the lying position 5; II (compare 3rd to 5 ) brought, and in particular about a pivot axis SWA12 in the lying position 5; 11 pivoted.

The armrests 4th are from the sitting position 4th ; I in the lying position 4; II brought in the armrests 4th parallel to the backrest 2nd , II are arranged. To do this, the armrests 4th (compare 2nd and 3rd ) around the swivel axis SWA4 panned. The armrests 4th remain around the swivel axis SWA during the swiveling process 4th throughout in a horizontal position, with the armrests 4th a corresponding actuator system.

Simultaneously with the backrest 2nd or then the headrest 3rd (compare 4th and 5 ) around the swivel axis SWA12 and in the lying position 2; 11 brought, the headrest 3rd in a so-called pre-lying position 3; II * is arranged. The headrest 3rd is finally based on the pre-lying position 3; II * the headrest 3rd also around a swivel axis SWA3 (compare 5 ) lowered, so that, according to the exemplary embodiment shown, a flat horizontal lying surface (lounger) is formed overall, which by the surfaces (from left to right, compare 5 ) the ottoman 6; II , the lower leg support 5; II , the seat part 1; II , the backrest I; II , the armrests 4; 11 (Underside of the armrest 4th in sitting position I. now forms the top of the lying surface in the lying position II ), the headrest 3; 11 is formed.

It is not shown that before or when reaching the lying position P; II a front of the headrest to further increase comfort 3rd is designed as an air cushion and is inflated or otherwise mechanically actuated.

• Wenn der Passagier nach Starten (= Programmstart S des Systems 100 der „Einschlafautomatik“) des Fahrzeuges die „Einschlafautomatik“ noch nicht aktiviert hat, kann der Passagier P durch eine Hinweis im HMI-Display aktiv motiviert werden das System 100 der „Einschlafautomatik“ zu aktivieren, wobei folgenden Prämissen verwendet werden.

Further design variants are proposed:

• If the passenger after starting (= program start S of the system 100 the "automatic sleep" of the vehicle has not yet activated the "automatic sleep", the passenger can P The system is actively motivated by a message on the HMI display 100 the "automatic sleep" to activate using the following premises.

The notice is given when the passenger P the position of the backrest 2nd from the sitting position I. in a relax position P; I / II changes at which the vehicle seat F from the upright sitting position I. in a comfortable, reclined, relaxed position F; I / II changes and / or the notification is given if the remaining driving time, the day / night time and / or the fatigue detection (system module 50 ) it seems likely that the sleep function would be comfortable. The passenger decides P on the criterion 10.2 in the system block 10th , which will be explained later, deliberately against it, after a program has already been started S of the system 100 the "automatic sleep" function is no longer automatically offered on this trip.

In addition, it is envisaged that in reverse to the "automatic sleep" function, the customer could be gently woken up by automatically resetting all the described ranges in good time, within a predeterminable period of time (for example 10 minutes) before reaching the destination.

It is also provided, for example, that shortly before reaching the lying position P; II could be used to further increase comfort, for example in the front of the headrest 3rd inflate a pillow.

The described "automatic sleep" is combined with a manual "semi-automatic" triggering of all the above-mentioned ranges, by means of which the vehicle seat F at the push of a button from the sitting position F; I to the sleeping position F; II brought.

In an alternative embodiment variant, the described "automatic sleep" is combined with a voice-based "semi-automatic" triggering of all of the above-mentioned ranges, by means of which the Vehicle seat F by a voice command from the sitting position F; I to the sleeping position F; II brought.

The following is an example of a program sequence between program start S (compare 6 ) and the end of the program E (compare 8th ) based on 6 to 8th explained in a flow chart.

The system components 10th , 20th , 30th , 40 , 50 , 60 , 70 , 80 are in the 6 to 8th displayed in rectangle boxes, while criteria or queries are shown in diamond boxes.

The program begins (compare 6 ) with the start of the program S .

After the program start S the seat angle is monitored continuously 10th , the status of the angle of the backrest 2nd opposite the seat part 1 is monitored. For this purpose, an angle sensor is arranged, which senses the status angle, between the upright sitting position F; I with the status angle 90 ° to 55 ° and the lying position F; II with the status angle 15 ° to 0 °. The intermediate position is referred to as the relax position, as has already been explained.

Then there is a query 10.1 , on which the status angle is <55 ° or> 15 °. This can determine whether the vehicle seat F in the relax position I / II or in the sitting position F; I or in the lying position F; II located.

The vehicle seat is located F not in the relax position I / II there is a jump back to the system module 10th before the criterion 10.1 back to the starting point of the system module 10th .

If the vehicle seat is already in the relax position according to the query 10.1 , it is assumed that the passenger P if necessary, would like to activate the automatic sleep.

The query to the passenger takes place in 10.2 P whether he wants to activate the automatic sleep timer?

This query 10.2 answered with "no", the program run is ended. If the question is answered with "yes", the program flow comes to the system module 20th , which continuously evaluates the driving situation.

The query takes place within the system block 20.1 whether a predeterminable remaining time to the travel destination is greater than a certain period of time, for example> 45 minutes? The user can adapt this time period to his needs in advance.

If the remaining travel time is less than the specified time, the program jumps to the criterion 20.1 back to the starting point of the system module 20th , especially because a sudden traffic jam could still lead to a significant increase in travel time afterwards.

If the remaining time is longer than the specified period of time, for example 45 minutes, the program jumps to the query 20.2 , in which by means of the system module 20th , the continuous evaluation of the driving situation determines whether the route ahead is suitable for sleeping? For example, if there is city traffic with a start / stop function or a particularly curvy route, the route is not suitable for sleeping, and from the criterion 20.2 there is a return to the system module 20th before the criterion 20.1 back to the starting point of the system module 20th .

If the route ahead is suitable for sleeping, the program sequence reaches (compare 6 and 7 ) the system module 30th in which there is continuous camera monitoring of the interior.

Using the system module 30th is in the criterion below 30.1 checked whether loose, unsecured objects can be detected in the interior.

If such loose, unsecured objects are found, this is done in the criterion 30.3 a note to the passenger P and a return to the system module 30th before the criterion 30.1 back to the starting point of the system module 30th , so that the program flow is not continued at first.

Are these loose items in the criterion 30.1 no longer detected, the program flow jumps to the criterion 30.2 in which it is still detected whether a table is folded out in the area of the interior or luggage is stowed away.

If a folded-out table or an unpacked baggage is found, the criterion is used again 30.3 a note to the passenger P and a return to the system module 30th so that the program only goes to the system block 40 jumps when the criteria 30.1 and 30.2 without notice to the passenger P are fulfilled. The program thus reaches the system module 40 , in which continuous camera surveillance of the passenger P is made.

Within the passenger's continuous camera surveillance P in system block 40 is used as a criterion 40.1 determined whether the passenger P wearing glasses. This detection takes place because it has been determined that the glasses could be damaged by turning the head when sleeping in the horizontal position of the passenger. Carries the passenger P glasses are in the criterion 40.4 a note to the passenger P discontinued and the system module returns 40 before the criterion 40.1 back to the starting point of the system module 40 . The program will not continue until it has been determined that the passenger P in the criterion 40.1 not wearing glasses, so the reference in the criterion 40.4 not happened.

In the subsequent criterion 40.2 it is determined whether the continuous camera surveillance is a sensory full body detection of the person P guaranteed.

If this is not the case, the system module is returned to 40 before the criterion 40.1 back to the starting point of the system module 40 . If this is the case, the program jumps to the criterion 40.3 , in which an unsuitable body position is determined, in which an automatic adjustment to the lying position P : II the person is not recommended. An unsuitable body position is thus detected and the query 40.3 answered with "yes", the program jumps to the system block 40 before the criterion 40.1 back to the starting point of the system module 40 back.

If there is a suitable body position, the system module 50 reached in the continuous sleep monitoring of the passenger P he follows.

Starting from the system module 50 in 7 is according to 8th a query 50.1 started, in which it is queried whether the passenger P fell asleep for longer than a predefinable period of time, especially longer than 5 minutes? If this is not the case, you will be returned to the system block 40 before the criterion 40.1 back to the starting point of the system module 40 so that procedure of continuous camera surveillance of the passenger P runs from the front.

Is the passenger P fell asleep longer than the specifiable period of time, for example> 5 minutes, the program sequence comes to the system module 60 in which the passenger P from the relax position P; I / II (compare criterion 10.1 ) to the lying position P; II is moved automatically.

It is provided that any media that are in operation, such as a radio or a monitor, for example, are switched off or hidden. In addition, the light in the interior of the vehicle is dimmed or switched off and the windows of the vehicle are darkened if possible. Thus, everyone is the person's sleep P disruptive influences minimized or no longer exist, so one for the passenger P comfortable sleeping situation is reached.

The program sequence then reaches the system module 70 , in which a continuous monitoring of the sleeping state of the passenger P and the time until the destination is reached is monitored.

The next step is in the criterion 70.1 queried whether the goal is reached within a predefinable time period, for example <40 minutes. If the goal is not reached within this specified time, the program jumps back to the system block 70 before the criterion 70.1 back to the starting point of the system module 70 , and if the goal is reached within the specified period of time, for example <40 minutes, the program jumps to the criterion 70.2 , in which it is queried whether the passenger is P is in deep sleep.

Within the criterion 70.2 is decided when the passenger P is in deep sleep, whether according to a criterion 70.3 the goal is reached in a predeterminable period of time of, for example, <20 minutes, the period in the criterion 70.3 is less than the time span 70.1 . These exemplary times are based on the average length of human deep sleep phases of 20 minutes, but can be adjusted to suit the user.

Is the criterion 70.3 If the program is not reached, the program jumps back to the system block 70 before the criterion 70.1 back to the starting point of the system module 70 , and is the goal within the criteria 70.3 the specified time span of <20 minutes, for example, the program jumps to the system block 80 , in which a wake-up scenario is carried out in which the vehicle seat F from the lying position F; II back to the (last) relax position P; I / II moves.

The system component 80 is also reached directly when queried 70.2 it is found that the passenger P is not in deep sleep. In this case, the query in the criterion is omitted 70.3 so that the system building block 80 is reached directly.

After the person is back in the relax position P; I / II is the original position according to the criterion 10.1 with the analogue sitting position originally available P; I / II of the passenger P restored.
