Description

The invention relates to a passenger cell for a motor vehicle, as well as to a motor vehicle.

Passenger compartments of motor vehicles are often divided into a front area and a rear area. At least one front seat, usually a row of two front seats, separates the front area from the rear area. These front seats are designed to accommodate front passengers, for example a driver of the motor vehicle and a front passenger, in the front area. In the rear area, at least one further seat is arranged as a rear seat, preferably a row of at least two rear seats, preferably parallel to the first row of front seats. These rear seats are designed to accommodate at least one rear passenger in the rear area.

The comfort requirements of vehicle occupants are also increasing in the rear area. Accordingly, individual air conditioning settings are possible in modern vehicles. For example, foot air flow openings and high air flow openings are provided for this purpose, through which at least one rear occupant can be supplied with air flow. The foot air flow opening is arranged below the at least one front seat in the vehicle floor or adjacent to the vehicle floor.

This arrangement of the foot air intake openings, which is known from industrial practice, means that dirt, which is brought into the passenger compartment via the shoes of the rear passengers, for example, can get into or through the foot air intake opening. In addition, floor mats or other floor coverings are often used in the foot area of the rear passenger compartment, which cover the foot air intake opening if it slips, for example. The foot air intake opening can also be covered by the feet or shoes of the rear passenger, so that an air flow for ventilating and air conditioning the rear area is at least partially blocked.

Based on this, the present invention is based on the object of at least partially overcoming the disadvantages known from the prior art. The features according to the invention arise from the independent claims, for which advantageous embodiments are shown in the dependent claims. The features of the claims can be combined in any technically reasonable manner, whereby the explanations from the following description and features from the figures can also be used, which include additional embodiments of the invention.

wobei die Luftführungseinrichtung zumindest eine Fußanströmöffnung für einen Fußbereich des Fondbereichs der Fahrgastzelle umfasst.The invention relates to a passenger cell for a motor vehicle with a longitudinal axis, comprising at least the following components:

• - a front area;
• - a rear area arranged along the longitudinal axis behind the front area; and
• - an air duct system for air conditioning the rear area of the passenger compartment,

wherein the air guiding device comprises at least one foot air flow opening for a foot area of the rear area of the passenger compartment.

The passenger cell is characterized primarily by the fact that the foot air flow opening is arranged to the side of the foot area with respect to the longitudinal axis.

Unless explicitly stated otherwise, ordinal numbers used in the preceding and following descriptions are used only to clearly distinguish them and do not reflect any order or ranking of the designated components. An ordinal number greater than one does not necessarily mean that another such component must be present.

A passenger cell for a motor vehicle is proposed here, which has a front area and a rear area. The passenger cell extends along a longitudinal axis, which also corresponds to the longitudinal axis of a motor vehicle with such a passenger cell and is arranged parallel to the direction of travel of the motor vehicle when driving straight ahead. The passenger cell also preferably comprises two opposing side walls and a vehicle floor.

The rear area is arranged along the longitudinal axis behind the front area, i.e. in the motor vehicle with respect to the direction of travel when driving straight ahead, behind the front area.

Preferably, the front area and the rear area are separated from one another by at least one front seat, particularly preferably a row of two or more front seats. The at least one front seat is designed to accommodate front passengers in the front area. For example, the at least one front seat is a driver's seat for accommodating a driver of the motor vehicle. Alternatively or additionally, at least one front seat is a passenger seat for accommodating a passenger. Preferably, there is at least one front air flow opening in the front area, preferably several front air flow openings. Openings are arranged through which an air flow for ventilation and air conditioning can be introduced into the front area.

At least one rear seat is arranged in the rear area, which is designed to accommodate a rear passenger in the rear area. Preferably, a plurality of rear seats, for example two or three rear seats, particularly preferably in a rear seat row, are arranged in the rear area.

The rear area can be air-conditioned by means of at least one foot air flow opening. For this purpose, an air flow can be provided by means of an air guide device, which can be introduced into a foot area through the foot air flow opening. The foot area is an area which is arranged in a lower part of the rear area, preferably in the vertical direction below a seat surface of the at least one rear seat and in front of a seat surface of the at least one rear seat in relation to the longitudinal axis. The foot area is particularly preferably an area in which a rear passenger positions his feet in a sitting position on the at least one rear seat.

It is now proposed here that the foot flow opening is arranged to the side of the foot region with respect to the longitudinal axis, i.e. at a horizontal angle of between 45° [forty-five degrees] and 135° [one hundred and thirty-five degrees], preferably between 60° [sixty degrees] and 120° [one hundred and twenty degrees], particularly preferably essentially 90° [ninety degrees] to the longitudinal axis. The horizontal angle is spanned in a horizontal plane.

Alternatively or additionally, the base flow opening is arranged at a vertical angle between 45° [forty-five degrees] and 135° [one hundred and thirty-five degrees], preferably between 60° [sixty degrees] and 120° [one hundred and twenty degrees], particularly preferably substantially 90° [ninety degrees] to the longitudinal axis. The vertical angle is spanned in a vertical plane.

The horizontal angle and/or the vertical angle are defined between the longitudinal axis and a surface normal to an opening area spanned by the foot flow opening.

The foot inflow opening preferably comprises a guide element by means of which the flow direction of the air flow flowing through the foot inflow opening can be influenced. For example, the guide element comprises pivotable slats. A mass flow of the air flow can preferably be influenced by means of the guide element. For example, the flow cross section of the foot inflow opening can be influenced by pivoting the slats.

By means of the passenger cell proposed here, blockage, covering and soiling of the foot air intake opening can be prevented or reduced.

It is further proposed in an advantageous embodiment of the passenger cell that at least one foot air flow opening is arranged in a side wall of the passenger cell and/or at least one foot air flow opening is arranged in a center console in the rear area.

According to an exemplary embodiment of this embodiment, it is now proposed that the (side wall-side) foot air flow opening is arranged in a side wall, preferably in both side walls, of the passenger compartment. For example, the side wall-side foot air flow opening is arranged in a lower support structure of the side wall, for example in a side wall section in the vertical direction between a door and the vehicle floor. The foot area is thus limited, for example, to the front by at least one front seat, to the rear by at least one rear seat and at least on one side by a side wall.

In one embodiment, the passenger compartment includes a center console in the rear area. For example, the center console extends continuously from the front area into the rear area between two front seats. In this embodiment, the foot area is laterally delimited by the opposite side wall and center console. In such an embodiment, a foot air flow opening (on the center console side) is preferably arranged in the center console.

This design of the passenger cell enables a low-loss guidance of the air flow, which can be guided through the foot air flow opening.

It is further proposed in an advantageous embodiment of the passenger cell that the foot air inlet opening and a high air inlet opening can be supplied with an air flow by means of at least a common section of a supply flow channel.

According to this embodiment, the passenger compartment further comprises at least one high-flow opening, preferably a plurality of high-flow openings. Particularly preferably, one high-flow opening is provided for each foot-flow opening. For example, one high-flow opening is provided on one side wall, preferably on both side walls, of the rear area and/or one, preferably two, high air flow opening arranged on the center console.

Preferably, the at least one high flow opening and the at least one foot flow opening can be supplied with air by means of a common section of the supplying flow channel. Preferably, at least those high flow openings and foot flow openings which are arranged in a common component of the passenger compartment, for example a common side wall or the center console, can be supplied with such a common section.

Such a passenger cell enables the air flow to be guided with low losses.

• - einer Seitenwand der Fahrgastzelle, bevorzugt unterhalb der Türen;
• - einer Mittelkonsole; und
• - einem Fahrzeugboden.

It is further proposed in an advantageous embodiment of the passenger compartment that a supply flow channel, preferably a section common to the foot flow opening and the high flow opening according to an embodiment according to the above description, is arranged in at least one of the following regions, preferably along the longitudinal axis at the level of the front region of the passenger compartment:

• - a side wall of the passenger compartment, preferably below the doors;
• - a center console; and
• - a vehicle floor.

According to this embodiment of the passenger compartment, the supply flow channel for the foot flow opening and/or the high flow opening is arranged at least in sections in the side wall of the passenger compartment, the center console and/or the vehicle floor. For example, the supply flow channel is arranged below the doors, i.e. vehicle doors for the rear area and/or the front area.

Preferably, at least the common section according to the above description is arranged at least in sections in the side wall of the passenger compartment, the center console and/or the vehicle floor.

Preferably, such a common section extends substantially along the longitudinal axis. For example, a common section of the supply flow channel is arranged in each of the two side walls, by means of which a (side wall-side) high flow opening and a side wall-side foot flow opening can be supplied, which are arranged on the side wall. Furthermore, such a common section is preferably arranged in the center console, by means of which a center console-side foot flow opening and a center console-side high flow opening can be supplied, which are arranged on the center console. Alternatively, such a common section is arranged below or adjacent to the center console or side wall. Preferably, the common section in each of the aforementioned embodiments runs through the front area of the passenger compartment along the longitudinal axis.

Such a passenger cell enables low-loss guidance of the air flow.

It is further proposed in an advantageous embodiment of the passenger cell that a supplying flow channel has a vertical section for supplying a high-flow opening, which is arranged in the B-pillar of the motor vehicle.

According to this embodiment, the supply flow channel has a vertical section which is arranged in the B-pillar of the motor vehicle or the passenger compartment. Such a vertical section is designed to supply the high-flow opening on the side wall with the air flow.

The supply flow channel preferably comprises a horizontal section for supplying the foot inflow opening on the side wall with the air flow. The vertical section and/or the horizontal section preferably border on the common section on the inflow opening side. The vertical section of the flow channel and the horizontal section are therefore connected to the common section. The horizontal section is preferably arranged to coaxially continue the common section. Such an arrangement of vertical, horizontal and common sections of the supply flow channel can also be implemented in the center console for the foot inflow opening or high inflow opening on the center console side.

An air guiding device of this design is particularly space-saving and enables low-loss guidance of the air flow.

• - eine Steuereinrichtung zum Steuern des Klimatisierens des Fondbereichs mittels der Fußanströmöffnung; und bevorzugt
• - eine in dem Fondbereich angeordnete Bedieneinheit, welche mit der Steuereinrichtung zum Steuern der Fußanströmöffnung verbunden ist.

It is further proposed in an advantageous embodiment of the passenger cell that the passenger cell further comprises the following components:

• - a control device for controlling the air conditioning of the rear area by means of the foot air inlet; and preferably
• - a control unit arranged in the rear area, which is connected to the control device for controlling the foot air flow opening.

According to this embodiment, the passenger compartment now has a control device for controlling the air conditioning of the rear area by means of the foot air flow opening. For example, the control device is designed to control an air conditioning device which provides and tempers the air flow. For example, the air conditioning device comprises fans, control flaps and/or tempering elements which can be controlled by means of the control device.

The control device comprises a computing device for carrying out computing steps, which is arranged inside or outside the passenger compartment. The control device also comprises a data memory, which has a data connection with the computing device and is arranged internally or externally with respect to the passenger compartment.

Preferably, a control flap arranged in the supply flow channel and/or the foot flow opening, which is formed for example by the guide elements, can be controlled by means of the control device.

The passenger compartment preferably comprises an operating unit arranged in the rear area, particularly preferably on the center console. The operating unit is designed to receive user inputs from a rear passenger. For example, the operating unit comprises a screen, preferably a touchscreen, push buttons, rotary knobs, voice control and/or other input means. The operating unit has a data connection with the control device in order to influence control of the air conditioning of the rear area using user inputs.

This embodiment provides a particularly simple and convenient setting and control of the air conditioning of the hairdryer area.

It is further proposed in an advantageous embodiment of the passenger cell that the passenger cell has a control flap for dividing the air flow between the respective foot air flow opening and the same-side high air flow opening.

According to this embodiment, it is now proposed that a control flap is designed to divide the air flow between the respective foot inflow opening and the high inflow opening on the same side. Accordingly, the control flap for controlling the air flow in the flow direction is arranged in front of or at a branch of the supply flow channel in the direction of a foot inflow opening and in the direction of an upper high inflow opening and/or between the branch and the lower foot inflow opening.

For example, such a branch is divided at the common section of the flow channel into the vertical section and the horizontal section.

With the design proposed here, the passenger cell can be implemented particularly cost-effectively and is less prone to errors.

It is further proposed in an advantageous embodiment of the passenger cell that the foot air flow opening is arranged in a vertically extending region of a center console and/or a side wall.

According to this embodiment, the foot air flow opening is arranged in a vertically extending region of the center console and/or the side wall. The vertically extending region is, for example, a wall of the center console or the side wall that extends vertically. A vertical extension here is understood to mean an extension in a plane that has an angle between 60° [sixty degrees] and 120° [one hundred and twenty degrees], or between 85° [eighty-five degrees] and 95° [ninety-five degrees], preferably 90° [ninety degrees]. The wall in which the foot air flow opening is arranged is arranged to the side of the footwell. This means that the wall extends in a vertical plane that is arranged essentially parallel to the longitudinal axis.

The foot air inlet is not arranged in a horizontal area of the foot area, for example the vehicle floor. According to this embodiment, the entry of dirt into the foot air inlet can therefore be avoided or reduced.

It is further proposed in an advantageous embodiment of the passenger cell that the foot air flow opening is arranged at a distance of at least 1 cm, preferably at least 2 cm, from a vehicle floor of the passenger cell.

According to this embodiment, the foot air flow opening is arranged at a minimum distance from the vehicle floor of the passenger compartment. The distance/minimum distance is at least 1 cm [one centimeter], preferably at least 2 cm [two centimeters].

The distance to the vehicle floor prevents or reduces the ingress of dirt into the foot air intake opening and prevents the foot air intake opening from being covered.

• - eine Antriebsmaschine zum Bereitstellen eines Antriebsmoments;
• - zumindest ein Vortriebsrad zum Umsetzen des Antriebsmoments in einen Vortrieb;
• - eine Fahrgastzelle nach einer Ausführungsform gemäß der obigen Beschreibung; und
• - eine Klimatisierungseinrichtung zum Klimatisieren der Fahrgastzelle.

According to a further aspect, a motor vehicle is proposed, comprising at least the following components:

• - a drive machine for providing a drive torque;
• - at least one drive wheel for converting the drive torque into propulsion;
• - a passenger compartment according to an embodiment as described above; and
• - an air conditioning system for air-conditioning the passenger compartment.

A motor vehicle is proposed here which comprises a drive machine, at least one drive wheel, a passenger compartment and an air conditioning device. The passenger compartment is designed as described above. The air conditioning device is set up to air-condition the passenger compartment. For this purpose, the air conditioning device is designed to provide an air flow which can be guided to the inflow openings (for example the foot inflow openings, the high inflow openings and front inflow openings) by means of the air guiding device. Accordingly, the flow channel of the fluid guiding device fluidically connects the inflow openings to the air conditioning device.

For example, the air conditioning system comprises fans, control flaps and/or temperature control elements that can be controlled by means of the control device.

Such a motor vehicle enables particularly low-loss air conditioning and ventilation of the rear area.

• 2: die Fahrgastzelle gemäß 1 in einer Detailansicht; und
• 3: eine Luftführungseinrichtung in einer perspektivischen Detailansicht.

The invention described above is explained in detail below against the relevant technical background with reference to the accompanying drawings, which show preferred embodiments. The invention is in no way limited by the purely schematic drawings, whereby it should be noted that the drawings are not dimensionally accurate and are not suitable for defining size ratios. It is shown in

• 1 : a motor vehicle with a passenger cell in a plan view;
• 2 : the passenger compartment according to 1 in a detailed view; and
• 3 : an air duct device in a perspective detailed view.

In 1 a motor vehicle 2 with a passenger cell 1 is shown in a top view. The passenger cell 1 comprises two side walls 10 and a vehicle floor 19 (not shown here), as well as two rows of seats, one row of front seats and one row of rear seats.

A front area 4 is defined in front of the front seats in the direction of travel. The front area 4 has several front air flow openings 25, two of which are shown here. The front area 4 of the passenger compartment 1 can be air-conditioned and ventilated using the front air flow openings 25. Preferably, each occupant or the front seats or body regions or sub-spaces of the front area 4 can be individually ventilated and air-conditioned. For this purpose, the motor vehicle 2 has an air conditioning device 24, which is arranged in the direction of travel in front of the front area 4 of the passenger compartment 1 as shown.

By means of an air guiding device 6 with a supply flow channel 17, an air flow can be guided from the air conditioning device 24 to the front air flow openings 25.

In the direction of travel behind the row of front seats, a rear area 5 is defined. The rear area 5 extends to the row of rear seats (rear seat row). The rear area 5 is laterally delimited by the side walls 10. In the rear area 5, a side wall-side foot air flow opening 7 is arranged on each of the two side walls 10 in order to flow to the foot areas 9 of the rear area 5. Two center console-side foot air flow openings 8 are arranged on the center console 11 opposite the side wall-side foot air flow openings 7. The foot air flow openings 7, 8 are thus arranged on both sides, to the side of the foot areas 9. The foot air flow openings 7, 8 and (not shown here) high air flow openings in the rear area 5 are also connected to the air conditioning device 24 by means of the supply flow channel 17 in order to be supplied with the air flow.

The supply flow channel 17 is divided into three channels in the present case. One channel runs through each of the side walls 10 and in the middle of the motor vehicle 2, for example in a center console 11 or in the vehicle floor 19. The flow channel 17 is preferably arranged in the respective side wall 10 in the vertical direction at a height between a door 18 and the vehicle floor 19.

The air conditioning device 24 draws, for example, an outside air flow, for example driven by the airstream, in order to provide the air flow for air conditioning the passenger compartment 1. Alternatively or additionally, the air conditioning device 24 is designed to draw the air flow from the passenger compartment 1 in a recirculation function. For example, the air conditioning device 24 comprises heating elements elements and/or cooling elements to control the temperature of the air flow.

The motor vehicle 2 further comprises at least one, preferably two or four, drive wheels 23 and a drive machine. A drive torque can be provided by means of the drive machine, which can be converted into propulsion by means of the drive wheels 23.

In 2 a detailed view of the passenger compartment 1 is shown. The air guiding device 6, which fluidically connects the air conditioning device 24 with the inflow openings (foot inflow openings 7,8, high inflow openings 12,13 and front inflow openings 25), is shown schematically. This is, for example, a passenger compartment 1 as in 1 shown, in this respect reference is made to the relevant description.

With an outside air supply as shown, an outside air flow is fed to the air conditioning device 24. In the air conditioning device 24, the air is tempered, for example. The air is distributed as an air flow to the inflow openings by means of the air guiding device 6. At least one or more flow channels 17 are formed in an area in front of the front area 4.

As shown, a flow channel 17 runs through the middle of the passenger compartment 1 and a flow channel 17 through the side wall 10. Several front channel sections branch off from the middle flow channel 17 in order to guide the air flow to front air inlet openings 25. The remaining middle flow channel 17 leads to the rear area 5. In the rear area, rear channel sections branch off in order to supply the foot air inlet openings 8 on the center console side and the high air inlet openings 13 on the center console side with the air flow.

As shown, a separate flow channel 17 is arranged in the side wall 10, which leads into the rear area 5. There, rear channel sections branch off to a foot flow opening 7 on the side wall side and a high flow opening 12 on the side wall side.

The flow channels 17 are thus guided in a straight line through the entire front area 4 and parts of the rear area 5 up to the foot air flow openings 7,8, so that flow losses are avoided.

In the rear area 5, a control unit 21 is provided on the center console 11, which enables a rear passenger to independently make control inputs for the air conditioning of the rear area 5 or his seating area.

In 3 a perspective detailed view of an air guiding device 6 is shown schematically. This is, for example, an air guiding device 6 according to 1 and or 2 .

The air guiding device 6 comprises the supply flow channel 17, which runs in the side wall 10 of the passenger compartment 1. The high-flow opening 12 on the side wall is designed to air-condition or ventilate the upper body regions of a rear passenger (for example a head and/or an upper body) or an upper section of the rear area 5. The high-flow openings 12, 13 are accordingly designed to direct the air flow to such areas, for example by means of guide elements (preferably slats). The foot-flow openings 7, 8 are designed and arranged accordingly to direct the air flow to the feet of the rear passenger or the foot area 9, for example by means of guide elements.

Accordingly, the high flow opening 12 is preferably arranged higher than the foot flow opening 7, as shown. For this purpose, a common section 14 of the supply flow channel 17 ends at a branch 26 under the B-pillar 20 of the motor vehicle 2. A control flap 22 is arranged in the branch 26, by means of which it can be controlled via a control device which mass flow of the air flow is to be guided through the high flow opening 12 or the foot flow opening 7.

At the branch 26, the channel is divided into a vertical section 15 and a horizontal section 16. The vertical section 16 runs through the B-pillar 20 to the high-flow opening 12 and the horizontal section 16 runs coaxially to the common section 14 and further parallel to the longitudinal axis 3 of the motor vehicle 2.

Such a routing of the flow channels 17, which avoids unnecessary curves, enables a low-loss air flow guidance.

The passenger cell proposed here makes it possible to achieve low-loss air conditioning of the rear compartment of a motor vehicle.
