Description

[0001] The present invention relates to a motor vehicle with a front seat having a backrest and a rear seat, as well as with a ceiling system having a ceiling adjustable between a state of use and a state of non-use, according to the preamble of claim 1.

[0002] From DE 10 2015 008 584 A1, a motor vehicle of this type is known, comprising a front seat with a backrest and a rear seat, as well as a ceiling system with a ceiling adjustable between a functional and a non-functional state. The ceiling system includes a housing and a removable ceiling stored within the housing for covering a user of the motor vehicle, wherein the ceiling is equipped with at least one comfort function and a control device controls at least one such comfort function. This is intended to create a motor vehicle with increased comfort.

[0003] From DE 10 2023 103 917 A1, an assembly is known comprising a vehicle seat and an anchor that is fixed relative to the vehicle seat. The assembly also includes a blanket that can be engaged with the anchor and inflated. Furthermore, the assembly includes a computer comprising a processor and memory that stores instructions for inflating the blanket in response to the detection of engagement between the blanket and the anchor, and for deflating the blanket in response to the detection of disengagement from the anchor.

[0004] From DE 38 04 060 A1 a vehicle equipment component is known which consists of a winding shaft which can be attached inside the vehicle in front of a seat and of a blanket which can be rolled up and down on it and serves as cold protection.

[0005] From DE 10 2017 217 368 A1, a vehicle seat is known with a lower seat part having a seat surface and a seat back having a backrest surface, wherein the lower seat part and / or the seat back is provided with an integrated cover device for a person sitting on the vehicle seat.

[0006] Generally, passengers sitting in the back of a vehicle, especially on a rear bench seat, can enjoy significantly greater comfort, as they don't have to concentrate on the road. Numerous entertainment systems are already available to enhance the comfort of these rear passengers. However, a disadvantage of existing vehicles is that, for example, a person sleeping in the back often finds the cabin too cold, leading to discomfort. To prevent this, the temperature in the passenger compartment can be increased, but this might then be perceived as unpleasant by the driver. A compromise can be achieved, for example, by providing a blanket for the person sitting in the back seat to cover themselves if they wish to sleep.However, such a blanket must be readily accessible and also stowable, and in the often cramped space conditions in the fund area, this leads to difficulties in covering up.

[0007] The present invention therefore deals with the problem of providing an improved or at least an alternative embodiment for a motor vehicle of the generic type, by means of which, in particular, covering a person sitting on a rear seat of a motor vehicle can be made easier and thereby their driving comfort can be increased.

[0008] This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0009] The present invention is based on the general concept of creating an automatic ceiling system in a motor vehicle that can fully automatically cover or uncover a person sitting in the rear seat, thereby significantly increasing driving comfort. The motor vehicle according to the invention has a front seat with a backrest, a rear seat, and a ceiling system with a ceiling that can be adjusted between an in use and a non-in use state. The ceiling system has a housing arranged in the backrest of the front seat for receiving the ceiling when it is not in use. Furthermore, the ceiling system has two driven, pivotable, and telescopic gripping arms arranged on the backrest of the front seat, by means of which the ceiling can be at least partially placed on a person sitting in the rear seat.Specifically, this means that the blanket can be automatically adjusted from its unused state, stored in the housing in the back of the front seat, to a used state, in which it at least partially covers the person sitting in the back seat, using the two gripping arms located on the backrest. The gripping arms can also be used to return the blanket to its unused state, thus significantly increasing comfort for the front passenger. This rear passenger therefore always has a blanket to cover themselves in the vehicle if they get cold, and the blanket system can be controlled fully automatically, so the rear passenger neither has to cover themselves nor worry about putting the blanket away.At the same time, this can elevate the driving experience to another level by drawing parallels to, for example, business class long-haul flights or rest areas, where blankets are also used.

[0010] In an advantageous embodiment of the motor vehicle according to the invention, the two gripping arms are rotationally fixed to a shaft that runs transversely to one direction of travel of the motor vehicle. By rotating the shaft, a simultaneous and uniform pivoting of the two gripping arms can thus be achieved, thereby eliminating the need for individual control of each of the two gripping arms and thus reducing both the control effort and the associated costs.

[0011] In a particularly preferred embodiment of the motor vehicle according to the invention, at least one telescopic gripper arm has a threaded rod. Such a threaded rod allows for relatively simple extension and retraction of the telescopic gripper arms, and also offers the advantage of a self-locking effect. Alternatively, it is of course also conceivable that the gripper arm is extended and retracted by means of a hydraulic or pneumatic piston-cylinder assembly.

[0012] Advantageously, an actuated gripper for grasping the blanket is arranged at one free end of each gripping arm. Such a gripper could, for example, be a simple spring-loaded clamp into which the blanket is held. Alternatively, a gripper that opens and closes independently is also conceivable, by means of which the blanket is only grasped when needed, i.e., for example, when covering or uncovering. Once the blanket system has covered the person sitting in the rear seat of the vehicle according to the invention, it is conceivable that the grippers on the gripping arms open and the gripping arms return to their rest position. In such a rest position, they lie, for example, snugly against or within the backrest of the front seat of the vehicle.

[0013] In a particularly preferred embodiment of the motor vehicle according to the invention, the housing can be closed with a pivoting flap. Such a pivoting flap thus prevents direct visual contact with the blanket arranged in the housing when not in use, resulting in a visually very appealing appearance of the rear of the front seat backrest. The pivoting flap can have a surface that is identical to the surrounding surface of the back of the seat backrest, allowing the housing of the blanket system, in which the blanket is housed when not in use, to be closed in a visually unobtrusive manner.

[0014] In a further advantageous embodiment of the motor vehicle according to the invention, the blanket is rolled up on a shaft within the housing when not in use. Rolling the blanket up on a shaft allows for particularly space-saving storage of the blanket in its unused state within the housing and also facilitates switching the blanket from its used state to its unused state with a simple rolling motion.

[0015] A spring mechanism connected to the shaft is advantageously provided, which is tensioned when the blanket is extended. Thus, when covering a person sitting in the back seat, the blanket is pulled out of the housing by the gripping arms and unwound from the shaft. Simultaneously, a spring mechanism connected to the shaft is tensioned. This spring mechanism can function similarly to a roller blind, where any desired position can be held, and when pulled, a locking mechanism is released, causing the spring mechanism to retract automatically. Alternatively, it is also conceivable that the shaft could be driven by an electric motor when retracting the blanket from its working state to its unused state.

[0016] In a further advantageous embodiment of the motor vehicle, a control device is provided that communicates with the ceiling system. In the simplest case, such a control device can be an operating button by means of which the extension or retraction of the ceiling is controlled.

[0017] In a further particularly preferred embodiment of the motor vehicle according to the invention, a detection device, communicating with the control unit, is provided for detecting the outline of a person sitting in the rear seat who is to be covered with a blanket. The control unit is designed such that it controls a covering movement of the gripping arms corresponding to the outline. This makes it possible to detect the size or build of the person sitting in the rear seat using the detection device and then to cover them optimally accordingly. For example, the blanket may be rolled out less for a smaller person sitting in the rear seat than for a larger person, so that the detection device and the control unit communicating with it always enable an individualized and optimal covering.

[0018] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0019] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the present invention. The components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawings.

[0020] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0021] Each of these shows, schematically: Fig. 1 a longitudinal section view through a motor vehicle according to the invention with a ceiling system having a ceiling in its non-use state, Fig. 2 a representation as in Fig. 1, however, with the ceiling partially extended, Fig. 3 a representation as in Fig. 2 with a person sitting in a rear seat of the motor vehicle who is at least partially covered by a blanket of the ceiling system, Fig. 4 a rear view of a front seat of the motor vehicle according to the invention, Fig. 5a an open gripper on a gripper arm of the ceiling system, Fig. 5b a representation as in Fig. 5a, however, with the gripper closed, Fig. 6 a cross-sectional view through the ceiling system.

[0022] According to the Fig. 1 - 3 A motor vehicle 1 according to the invention comprises a front seat 3 having a backrest 2, a rear seat 4 arranged behind it in the direction of travel, and a ceiling system 5. The ceiling system 5 has a function that can be adjusted between a use state (compare Fig. 3) and a non-used state (compare Fig. 1) Adjustable blanket 6. The blanket 6, when in use, serves to cover and thus keep warm a person 7 sitting in the back seat 4, who, for the sake of clarity, is only shown in Fig. 3 is marked.

[0023] The ceiling system 5 has a housing 8 arranged in the backrest 2 of the front seat 3 for receiving the ceiling 6 when not in use, and two driven, swiveling and telescopic gripping arms 9 arranged on the backrest 2 of the front seat 3 (see also the Fig. 4 - 6), with which the blanket 6 can be extended from the housing 8 and placed at least partially on the person 7 sitting in the rear seat 4.

[0024] If one considers the Fig. 1, it can be seen that the cover 6 is rolled up inside the housing 8 on a shaft 10 (compare also Fig. 6). The housing 8 or a pull-out slot for the blanket 6 is closed by a swiveling flap 11, so that the blanket 6 is stored in a visually unobtrusive manner in the backrest 2 of the front seat 3 when not in use.

[0025] The two gripping arms 9 are rotationally fixed to a drive shaft 12 (see also the Fig. 4) coupled, which can be driven, for example, by a drive unit 13, in particular an electric motor. A rotation of the drive shaft 12 causes the two gripping arms 9 to pivot, as is the case, for example, according to the Fig. 1 - 3 is shown. In the Fig. In steps 1-3, the drive shaft 12 is rotated approximately 100° counterclockwise. Simultaneously, the gripping arms 9 extend telescopically, allowing them to place the blanket 6 on the person 7. The drive shaft 12 typically runs transversely to the direction of travel of the vehicle 1.

[0026] The telescopic gripping arms 9 can be extended and retracted using a threaded rod or a hydraulic or pneumatic piston-cylinder unit. The advantage of a threaded rod is, for example, its self-locking effect. A piston-cylinder unit allows for faster extension and retraction of the gripping arms 9.

[0027] At one free end of each of the gripping arms 9 is an actuated gripper 14 (see in particular the Fig. 5a and Fig. 5b) arranged, by means of which the ceiling 6 can be fixed or released. The gripper 14 can be designed analogously to a pair of pliers, with two jaw ends 19 which, when gripped (compare Fig. 5b) Fix the ceiling 6.

[0028] Looking again at the Fig. 1, Fig. 4 and Fig. Figure 6 shows that in this state, the blanket 6 is rolled up onto the shaft 10. For this purpose, the shaft 10 can, for example, have a spring mechanism 15 which is tensioned when the blanket 6 is extended. Such a spring mechanism 15 can function, for example, like a window blind and be fixed in any desired position, only to be released when pulled. The blanket 6 is then rolled up onto the shaft 10 by means of the spring mechanism 15. Alternatively, it is of course also conceivable that the shaft 10 is rotated by another drive mechanism, not shown, such as an electric motor.

[0029] To activate the ceiling system 5, a control device 16 can be used (compare Fig. 1), in particular in the simplest case a button 18, is provided which, when pressed via the control device 16, activates the ceiling system 5, i.e., extends the ceiling 6, or deactivates it, i.e., retracts the ceiling 6.

[0030] In a particularly preferred embodiment of the motor vehicle 1 according to the invention, it is also conceivable that a detection device 17 (compare) is connected to the control device 16 in a communicative manner. Fig.3) is provided for detecting the outline of the person 7 sitting on the rear seat 4 and to be covered with the blanket 6, wherein the control device 16 is designed such that it controls a covering movement of the gripping arms 9 according to the outline transmitted by the detection device 17. Such a detection device 17 can, for example, be designed as a camera that detects the size and build of the person 7 sitting on the rear seat 4 and controls the covering with the blanket 6 accordingly. This allows the covering movement to be optimally adapted to the individual build of the person 7, thereby significantly increasing the travel comfort for the person 7.

[0031] Everything in the vehicle 1 can be significantly enhanced by the automated covering system 5, which allows for a greater sense of well-being and driving comfort. A person 7 sitting in the back seat 4 can be covered easily and quickly, for example, if they are cold. The blanket system 5 is fully automated, so the person 7 does not have to cover themselves or worry about putting away or storing the blanket 6. The detection device 17 allows the covering motion to be adjusted to different sizes or builds of the person 7. Ideally, the control device 16 or a simple button 18 allows the covering to be done at the touch of a button, requiring no further action, thus significantly increasing user-friendliness.
