Description

The present invention relates to a headliner system for motor vehicles and a motor vehicle with a headliner system.

For air conditioning of a passenger compartment, motor vehicles often have an air conditioning unit (also referred to as an air conditioning system) which is usually fluidly connected to air outflow devices arranged, for example, in the area of the dashboard and/or in the area of a central tunnel (for front passengers). In correspondingly designed motor vehicles, a conditioned air flow (heated and/or cooled and/or air humidity-adjusted air flow) is consequently output to passengers in the passenger compartment frontally.

A corresponding frontal discharge of conditioned air onto passengers can be perceived as unpleasant by the passengers, since the discharged conditioned air streams can, for example, hit the passengers' eyes directly, which can lead to irritation of the eyes. Furthermore, such air currents can be perceived as unpleasant, since body areas directly exposed to the air current can cool down, which can lead to local cooling and associated muscle tension.

To counter this problem, from the DE 198 32 738 A1 a motor vehicle is known, in which the roof of a passenger compartment has an air distribution chamber, which adjoins the passenger compartment with an air outlet wall that extends over a flat area in the direction of the surface area of the roof. The air outlet wall is provided with a large number of finely distributed openings, through which the air supplied to the air distribution chamber enters the passenger compartment with extensive air fronts.

That from the DE 198 32 738 A1 well-known headliner system enables a more even flow of passengers in the passenger compartment. However, that is from the DE 198 32 738 A1 known headliner system is not suitable for a motor vehicle with a sunroof or with a panoramic roof, the roof of which has glass surfaces at least in sections.

The present invention is based on the object of providing a roof lining system by means of which air, for example conditioned air, can be introduced into a passenger compartment of a motor vehicle and which is suitable for motor vehicles with a sliding roof and/or with a panorama roof.

The object on which the present invention is based is achieved by a roof liner system for motor vehicles having the features of claim 1 . Advantageous refinements of the roof lining system are described in the claims dependent on claim 1 .

More precisely, the object on which the present invention is based is achieved by a roof liner system for motor vehicles, which has at least one air supply connection for connecting the roof liner system to an air conditioning unit of the motor vehicle and at least one outflow device which is fluidly connected to the at least one air supply connection by means of at least one air supply channel. The roof lining system is characterized in that it is designed so that the at least one air supply duct can be fastened to a roof rail of a motor vehicle.

The correspondingly designed roof liner system has the advantage that air (for example conditioned air) can be introduced via the roof liner system into a headspace of a passenger compartment of a motor vehicle equipped with the roof liner system according to the invention, the roof liner system also being suitable for motor vehicles with a sliding roof and/or with a panoramic roof is. Because a sliding roof or a panoramic roof is still accessible in a motor vehicle with the roof lining system according to the invention.

The at least one outflow device is designed to emit an air flow which, when the roof liner system is installed in a motor vehicle, extends downwards from a roof liner area into the passenger compartment. Consequently, the air flow has a predominantly vertical orientation in the passenger compartment.

The outflow device can also be referred to as an air outflow device. The at least one outflow device is preferably designed as a vertical outflow device, so that the airflows emerging from the central outflow area and from the edge outflow area are discharged essentially vertically from the roof lining into the passenger compartment.

The headliner system preferably has more than one outflow device. The roof liner system preferably has at least two, more preferably at least three and even more preferably at least four outflow devices. More preferably, the headliner system has a number of outflow devices corresponding to the number of passengers on. The outflow devices are also preferably designed to be structurally identical to one another. More preferably, the headliner system has further additional outflow devices for the windshield and/or for the rear window and/or for the side windows of the motor vehicle.

The headliner system preferably has at least two air supply connections. More preferably, a first outflow device is fluidly connected to a first air supply connection. More preferably, a first and a second outflow device are fluidly connected to a first air supply port. More preferably, a first and a second outflow device are fluidly connected to a first air supply port and a third and a fourth outflow device are fluidly connected to a second air supply port.

The roof lining system can be designed in such a way that the at least one air supply duct can be arranged at least in sections in a receiving space of the roof rail.

The headliner system can also be designed in such a way that the entire at least one air supply duct can be arranged in a receiving space of the roof rail.

The roof liner system can be designed such that the at least one air supply duct has an outer contour that corresponds to an inner contour of the receiving space of the roof pillar, so that the air supply duct nestles into the roof pillar at least in sections.

A central area of the headliner system is free, so that a sunroof and/or a panorama roof is/are still freely accessible. Consequently, the roof liner system has a through opening or a recess in the central area.

The roof lining system can have a number of heating devices corresponding to the number of outflow devices for heating an air flow to be emitted by the respective outflow device, each heating device being arranged between the at least one air supply connection and an outflow device assigned to the heating device.

The correspondingly designed roof lining system has the advantage that the on-board air conditioning unit only has to provide an air flow at one temperature, the air flows emitted by the respective outflow devices being heated by means of the respective heating devices in such a way that preset temperatures in the passenger compartment in the different below the respective Outflow devices located vehicle areas can be set and achieved.

An air flow discharged from the headliner system goes through the following path: air conditioner -> air supply port -> heater -> outflow area.

The heating device or heating devices are preferably designed as a flow-through heating device or flow-through heating devices. For this purpose, each heating device has a through-channel through which the air flow to be acquired is passed.

The roof lining system can be designed in such a way that at least one airbag can be accommodated in the air supply duct.

The appropriately designed roof liner system has the advantage that a receiving space of a roof pillar of the motor vehicle is used efficiently for the air supply duct and at the same time the safety of a motor vehicle equipped with the appropriately designed roof liner system is increased. This is because, due to the integration of the airbag in the air supply duct, an enlarged cross-sectional area of the roof rail or of the air supply duct can be used for an air flow. In a motor vehicle in which the airbag would be arranged inside the roof rail but outside the air supply duct, the air supply duct would have to be made smaller.

A corresponding configuration of the roof lining system is not obvious since the air supply duct usually prevents the airbag from expanding when an airbag is deployed.

The airbag can also be referred to as an impact bag, air cushion, air bag or protective cushion.

The airbag is preferably a curtain airbag, which can also be referred to as a side airbag or head airbag.

Furthermore, the roof lining system can be designed so that the at least one airbag can be fastened to a roof pillar of the motor vehicle through a wall of the air supply duct.

The correspondingly designed roof liner system is particularly easy to install in a motor vehicle.

For example, the airbag can be fastened to the roof rail by means of at least one fastening means (eg a screw) protruding through the wall of the air supply duct.

Furthermore, the roof lining system can be designed so that the at least one air supply duct can be fastened to the roof rail of the motor vehicle by means of the at least one airbag.

The correspondingly designed roof liner system is particularly easy to install in a motor vehicle.

Furthermore, the roof lining system can be designed so that the at least one air supply duct has a predetermined breaking point at which the air supply duct splits when the at least one airbag is deployed.

Due to the provision of the predetermined breaking point in the air supply duct, the air supply duct is even less in the way of an expansion of the airbag when the airbag is deployed, so that the safety of a motor vehicle equipped with the appropriately designed roof lining system is further increased.

The predetermined breaking point can be designed to be airtight or essentially airtight, so that the air conducted from the air conditioning unit via the air supply duct cannot or essentially cannot escape via the predetermined breaking point into the passenger compartment of the motor vehicle.

Furthermore, the headliner system can be designed such that the predetermined breaking point is formed by a thinning of a wall of the air supply duct.

The appropriately designed headliner system has the advantage that the air supply duct is also absolutely airtight in the area of the predetermined breaking point.

A wall thickness of the air supply duct in the area of the predetermined breaking point is smaller than a wall thickness in an area adjacent to the predetermined breaking point.

The roof lining system can be designed such that the at least one air supply duct has a first part and a second part that can be connected to one another.

The correspondingly designed headliner system has the advantage that it can be installed even more easily in a passenger compartment and in particular on a roof pillar of a motor vehicle. Furthermore, an airbag can be positioned particularly easily within the air supply duct in the case of the correspondingly designed headliner system. In a further simplified manner, the airbag can be fastened to the roof rail of the motor vehicle by a wall of the first part. After the airbag and thus the first part has been attached to the roof rail, the second part can be connected to the first part. The connection of the second part to the first part is airtight or substantially airtight.

The first part can also be referred to as the upper part and the second part can also be referred to as the lower part of the air supply duct.

Furthermore, the roof lining system can be designed such that the first part and the second part can be connected to one another by means of a tongue and groove connection.

The correspondingly designed headliner system has a simple structure and is easy to assemble.

The first part preferably has a groove into which the second part can be inserted. However, it is also possible for the second part to have a groove into which the first part can be inserted.

Furthermore, the first part and the second part can be connected to one another by means of a latching connection. For example, the first part has latching tongues and/or latching projections and the second part has corresponding latching openings and/or latching depressions. It is of course also possible for the first part to have latching openings and/or latching depressions and for the second part to have corresponding latching tongues and/or latching projections.

The roof lining system can be designed so that the first part of the air supply duct can be fastened to the roof rail of the motor vehicle by means of the at least one airbag.

The correspondingly designed roof liner system is particularly easy to install in a motor vehicle.

The roof liner system can be designed in such a way that the roof liner system has expanded polypropylene (EPP) and/or expanded polyethylene (EPE) and/or expanded polystyrene (EPS) and/or expanded polyamide (EPA).

The correspondingly designed headliner system has the advantage that it is light in weight. Another advantage of the appropriately trained headliner system is its compared to from the prior tech nik known headliner systems and air conditioning systems much improved suitability for recycling (recycling). This is because roof liner systems known from the prior art have a multi-layer sandwich structure, which makes it considerably more difficult to recycle the materials used. Furthermore, the correspondingly designed headliner system has the advantage that the headliner system has low thermal conductivity and thus increased thermal insulation. In addition, the correspondingly designed headliner system has both improved acoustic and improved mechanical damping properties. In addition, the correspondingly designed headliner system has an advantageous elastic deformability, so that in the event of an accident, passengers are better protected when they come into contact with the headliner system. A further advantage of the correspondingly designed roof liner system is that the mold for producing the roof liner system can be made of aluminum, for example, which leads to reduced tool costs for the mold and thus to reduced manufacturing costs of the roof liner system.

The headliner system can be designed such that the first part is formed from expanded polypropylene.

The correspondingly designed headliner system has particularly advantageous thermal properties. When installing the appropriately designed headliner system in a motor vehicle with a sunroof and/or panoramic roof, the headliner system and in particular the at least one air supply duct is exposed to a large amount of heat from solar radiation. Due to the formation of the first part at least partially from expanded polypropylene, the headliner system and in particular the air supply duct and thus the air to be transported into the passenger compartment heat up less.

Of course, the first part can also be made entirely of expanded polypropylene.

The headliner system can be designed in such a way that the second part is designed as an injection molded part.

The correspondingly designed roof lining system has a low overall height, so that a headroom in a passenger compartment of a motor vehicle equipped with the correspondingly designed roof lining system has an enlarged headroom or more headroom.

The second part has, for example, polypropylene (PP) and/or polyamide (PA6) and/or polyamide (PA6.6) and/or polycarbonate (PC) and/or acrylonitrile butadiene styrene copolymer (ABS) and/or polybutylene terephthalate ( PBT) and/or polystyrene (PS) and/or polyacrylonitrile (PAN).

The roof lining system can be designed in such a way that the at least one outflow device can be fastened to a roof, in particular to a panorama roof of a motor vehicle.

For example, the at least one outflow device can be bonded to a roof, in particular to a panorama roof.

The roof lining system can be designed so that the air supply duct is U-shaped in plan view.

The correspondingly designed roof lining system has the advantage that air provided by the air conditioning unit can be supplied to outflow devices that are positioned on different sides of the passenger compartment (e.g. driver's side and passenger side) in an improved manner. Thus, the appropriately designed headliner system enables a passenger compartment to be supplied with air provided by the air conditioning unit.

The headliner system may be configured such that the air supply duct has a first leg and a second leg, at least one first outflow device being fluidly connected to the first leg and at least one second outflow device being fluidly connected to the second leg.

This correspondingly designed roof lining system also has the advantage that air provided by the air conditioning unit can be supplied to outflow devices that are positioned on different sides of the passenger compartment (e.g. driver's side and passenger side) in an improved manner. Thus, the appropriately designed headliner system enables a passenger compartment to be supplied with air provided by the air conditioning unit.

The roof lining system can be designed in such a way that at least two outflow devices are fluidly connected to the first leg and at least two further outflow devices are fluidly connected to the second leg.

The present invention is also based on the object of providing a motor vehicle which air-conditioning the passenger or passengers with conditioned air from the roof liner made possible, while at the same time a sunroof and / or a panoramic roof of the motor vehicle remains essentially freely accessible and usable.

This object on which the present invention is based is achieved by a motor vehicle having the features of claim 16 .

More precisely, the object on which the invention is based is achieved by a motor vehicle with an air conditioning unit for air conditioning a passenger compartment of the motor vehicle and with a roof pillar, the motor vehicle being characterized in that the motor vehicle has a roof liner system as described above, the at least one air supply connection of the roof liner system is connected to the air conditioning unit, so that air provided by the air conditioning unit can be introduced into the passenger compartment of the motor vehicle via the at least one outflow device of the roof lining system, and wherein the at least one air supply duct is attached to the at least one roof rail.

The motor vehicle can have a sunroof and/or a panoramic roof. The correspondingly designed motor vehicle allows the passenger or passengers to flow from the roof liner in an essentially draught-free manner, while at the same time the sunroof and/or the panoramic roof of the motor vehicle remain essentially or even completely freely accessible and therefore usable.

As already described above with reference to the roof lining system, the motor vehicle can have at least one airbag which is arranged in the air supply duct of the roof lining system and is fastened in the manner described above.

Further advantages, details and features of the invention result from the exemplary embodiments explained below. Show in detail:

• 1 1: a schematic cross-sectional illustration of a passenger compartment of a motor vehicle according to the invention, in which a roof lining system according to the invention is installed;
• 2A Fig. 1: shows a schematic cross-sectional representation of a roof rail of a motor vehicle not belonging to the present invention;
• 2 B 1: shows a schematic cross-sectional representation of a roof pillar of a motor vehicle according to the invention; and
• 3 : a perspective representation of a roof liner system according to the invention from diagonally above.

In the description that now follows, the same reference symbols denote the same components or the same features, so that a description of a component carried out with reference to one figure also applies to the other figures, so that a repeated description is avoided. Furthermore, individual features that have been described in connection with one embodiment can also be used separately in other embodiments.

1 shows a schematic cross-sectional illustration of a passenger compartment 70 of a motor vehicle according to the invention, in which a roof lining system 1 according to the invention is installed. The roof lining system 1 according to the invention is shown in a perspective representation obliquely from above in 3 shown, where a roof 60 of the motor vehicle, in which the roof liner system 1 is installed, is partially not shown, so that the structure of the roof liner system 1 can be seen more clearly.

The roof liner system 1 has at least one air supply connection 10 for connecting the roof liner system 1 to an air conditioning unit of the motor vehicle, not shown in the figures. The air supply connection 10 is in fluid communication with outflow devices 30 - 34 via an air supply duct 20 , the outflow devices 30 - 34 being designed to discharge an air flow L1 into the passenger compartment 70 . For this purpose, the outflow devices 30 - 34 each have at least one opening on their respective walls facing the passenger compartment 70 . Out of 1 It can be seen that the air flow L1 is oriented essentially vertically and is directed from the headliner or from the roof 60 of the motor vehicle in the direction of the passenger P located under the outflow device 30-34.

How out 3 As can be seen, the air supply duct 20 has a first leg 25 and a second leg 26, so that the air supply duct 20 is U-shaped in plan view. A first outflow device 31 and a third outflow device 33 are supplied via the first leg 25 with air which is supplied to the roof lining system 1 from the air conditioning unit via the air supply connection 10, and a second outflow device 32 and a fourth outflow device 34 are supplied via the second leg 26 supplied with air supplied to the headliner system 1 from the air conditioner via the air supply port 10 . The air supplied from the air conditioner through the air supply port 10 is transported via air flows L2 within the roof lining system 1 from the air supply connection 10 via the first leg 25 of the air supply channel 20 to the first outflow device 31 and to the third outflow device 33 . Furthermore, the air supplied by the air conditioner via the air supply connection 10 is transported via air flows L2 within the roof lining system 1 from the air supply connection 10 via the second leg 26 of the air supply duct 20 to the second outflow device 32 and to the fourth outflow device 34. The air is discharged from the four outflow devices 30-34 into the passenger compartment 70 in each case via air streams L1.

The respective outflow devices 30-34 are attached to the roof 60 of the motor vehicle. In the exemplary embodiment shown, the respective outflow devices 30 - 34 are connected to the roof 60 by means of an adhesive bond 61 . However, the present invention is not limited to the outflow devices 30 - 34 being connected to the roof by means of an adhesive bond 61 . Non-positive and/or positive connections of the respective outflow devices 30 - 34 to the roof 60 are also possible according to the invention.

Out of 1 It can also be seen that the roof lining system 1 has a recess 2 or an opening 2 in its central area, which is bordered by the air supply duct 20 and the outflow devices 30-34. A roof 60 or a panorama roof 60 is thus essentially freely accessible and light can enter the passenger compartment 70 via the panorama roof 60 .

Out of 1 and from 2 B It can be seen that the at least one air supply duct 20 is attached to a roof rail 50 of the motor vehicle. For this purpose, the at least one air supply duct 20 has an outer contour that corresponds to an inner contour of the roof rail 50 or the roof rails 50 . The air supply duct 20 thus fits snugly into a receiving space defined by the roof rail 50 . Consequently, the accommodation space defined by the roof rail 50 is used efficiently for the air supply duct 20 and thus for guiding the air to be discharged into the passenger compartment 70 .

From the 1 and 2 B It can also be seen that an airbag 40 is accommodated in the air supply duct 20 . For this purpose, the airbag 40 is attached to the roof rail 50 by a wall 23 of the air supply duct 20 . Consequently, the air supply duct 20 is fixed to the roof rail 50 of the motor vehicle by means of the airbag 40 .

The advantage of positioning the airbag 40 in the air supply duct 20 is that a receiving space of the roof rail 50 is used efficiently for the air supply duct 20 and at the same time the safety of a motor vehicle equipped with the appropriately designed roof lining system 1 is increased. This is because, due to the integration of the airbag 40 in the air supply duct 20, an enlarged cross-sectional area of the roof rail 50 or of the air supply duct 20 can be used for an air flow. In a motor vehicle in which the airbag 40 would be arranged inside the roof rail 50 but outside the air supply duct 20, the air supply duct 20 would have to be made smaller, as is shown in 2A can be seen.

As further from the 1 and 2 B As can be seen, the air supply duct 20 has a first part 21 which is designed as an upper part 21 and a second part 22 which is designed as a lower part 22 . The lower part 22 is attached to the upper part 21 . For example, the upper part 21 and the lower part 22 can be connected to one another by means of a tongue and groove connection, not shown in the figures.

Due to the two-part configuration of the air supply duct 20, the upper part 21 of the air supply duct 20 is fastened to the roof rail 50 of the motor vehicle by means of the airbag 40. The lower part 22 is in turn attached to the upper part 21 . Due to the two-part configuration of the air supply duct 20, the airbag 40 can be inserted more easily into the air supply duct 20 and, in addition, the air supply duct 20 can also be fastened to the roof rail 50 more easily.

At the in the 1 and 2 B illustrated embodiment of the roof lining system 1, the air supply duct 20 has a predetermined breaking point 24. Due to the provision of the predetermined breaking point 24 in the air supply duct 20, the air supply duct 20 is less opposed to an expansion of the airbag 40 when the airbag 40 is deployed, so that the safety of the motor vehicle equipped with the roof lining system 1 is increased.

The predetermined breaking point 24 is designed to be airtight or essentially airtight, so that the air routed from the air conditioning unit via the air supply duct 20 cannot or essentially cannot escape via the predetermined breaking point 24 into the passenger compartment 70 of the motor vehicle.

In the exemplary embodiment shown, the predetermined breaking point 24 is formed in a boundary area between the upper part 21 and the lower part 22 . However, the present invention is not limited to the fact that the predetermined breaking point 24 in the border area between the upper part 21 and the Lower part 22 is formed. It is of course also possible for the predetermined breaking point 24 to be formed in the lower part 22 . Furthermore, it is of course also possible for the predetermined breaking point 24 to be formed in the upper part 21 .
