Description

The invention relates to a lining of a passenger compartment of a motor vehicle with an area that can be exposed to the passage of light, sound and / or air.

By “cladding” is meant by passengers of a motor vehicle visible and touchable, flat surfaces that delimit the passenger compartment or plate-shaped, flat or non-flat components that delimit the passenger compartment in a motor vehicle. However, the cladding can also be arranged in an invisible and / or non-touchable position of a passenger compartment in the motor vehicle.

The openable area, when it is open, is used, in particular, to allow air to pass in one or both directions, i.e. to ventilate and / or vent the passenger compartment, to pass sound in one or both directions, for example to emit acoustic signals Signals or speech from a loudspeaker or another sound source arranged behind or under the cladding as seen from the passenger compartment or for receiving speech from a driver, front passenger or other occupants of the passenger compartment with, for example, a microphone arranged behind or under the cladding as seen from the passenger compartment and / or to illuminate the passenger compartment or of instruments, displays, switches and the like in the passenger compartment or as an area of the trim of the passenger compartment illuminated for aesthetic or other reasons.

The object of the invention is to propose a lining for a passenger compartment of a motor vehicle with an area which is open to the passage of light, sound and / or air and which has an unusual appearance in the open state.

This object is achieved by the features of claim 1.

The panel according to the invention has an openable area in which the panel has slots. The slots are arranged on imaginary lines with basically any course, the distance between adjacent lines being constant or changing. The lines can, for example, be straight, angled, arc-shaped, annular or annular with a round shape other than circular or polygonal. Annular lines preferably enclose one another, the rings being concentric or eccentric.

Slots are arranged one behind the other in the longitudinal direction on the imaginary lines and next to one another on adjacent lines. The slots run, at least when they are closed, preferably in the direction of the lines on which they are arranged, but can also be at an acute angle, preferably at an angle of not more than 30 °, 20 ° or 10 ° to the lines be arranged.

Slots arranged one behind the other on a line are spaced apart. Slits on adjacent lines have an offset in their longitudinal direction or in the direction of the lines on which they are arranged. Seen transversely to the lines, a first slot, which is arranged on a first line, covers the distance between a second and a third slot, which are arranged directly, that is to say without a further slot between them, one behind the other on a second line, which is the first line is adjacent. In other words, the slots are arranged side by side behind and with an offset in their longitudinal direction in such a way that the slots expand into openings when the openable region of the cladding is stretched transversely to the imaginary lines or transversely to the slots.

To open and / or close the slots, the cladding has an actuator with which the cladding can be deformed perpendicularly or obliquely to its surface in the openable area. As a result, the openable area of the cladding is stretched or compressed and the slots and thus the openable area are opened or closed. If the slots are open, the openable area can also be interpreted as open. An actuator is to be understood as a device that generates a mechanical movement. The actuator can generate the movement, for example, electromechanically with, for example, an electric motor, an electromagnet, a piezo element, pneumatically, hydraulically or with a shape memory alloy. The actuator can also be driven manually, for example via an actuating element and a transmission.

The invention enables a passenger compartment of a motor vehicle to be clad with an area which is open to the passage of light, sound and / or air and which, when closed, can be made invisible or barely visible and / or has an unusual appearance when open , It is possible to close the slots tightly, but it is not fundamentally provided, even incomplete closing of the slots is possible.

In one embodiment of the invention, the slots, when open, form hexagonal openings or diamond-shaped openings.

An embodiment of the invention provides that the openable area, when open, is dome-shaped and its curvature when opened increased. "Dome" means a two-dimensional in one direction, that is, depending on the direction of view, concave or convex curved surface. When the openable area is closed, it can be flat or dome-shaped, but with a smaller curvature than when it is open.

In the openable area, the cladding is preferably thinner than in an area surrounding the openable area, so that when opening and closing only the openable area is deformed, or in any case the openable area is deformed several times more than the area surrounding the openable area.

One embodiment of the invention provides that the cladding in the openable area is not thicker than about 10% or 5% of a distance between two successive slots which are arranged directly behind one another on a line.

The cladding is preferably made of plastic and / or is elastically deformable in the openable area.

The features and combinations of features, configurations and configurations of the invention mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or drawn in a figure, are not only in the respectively specified or drawn combination, but also in any other Combinations or can be used individually. Embodiments of the invention are possible which do not have all the features of a dependent claim. Individual features of a claim can also be replaced by other disclosed features or combinations of features.

The invention is explained in more detail below with reference to an embodiment shown in the drawing. Show it:

• 1 a dashboard of a motor vehicle as a lining of a passenger compartment of the motor vehicle with an openable area according to the invention in a perspective view, the openable area being open;
• 2 a view of the openable area 1 in the closed state;
• 3 a cross section of the openable area and a region of the cladding surrounding the openable area 1 and 2 with closed openable area; and
• 4 the cross section 3 with open open area.

1 shows a dashboard of a motor vehicle, not shown, the top or a panel 1 a passenger compartment of the motor vehicle according to the invention. The cladding has in its top 1 an area that is circular in view and can be opened 2 on, the openable area 2 can have other shapes. Instead of the dashboard, another trim or interior trim part of the motor vehicle, such as, for example, a door interior trim, a center console or a trim on the rear of a front seat of the motor vehicle, can have the openable area and form the trim according to the invention (not shown).

In the openable area 2 is the disguise 1 with slits 3 provided that to hexagonal, diamond-shaped or similarly shaped openings 4 are widened when the slits 3 and thus the openable area 2 are open. 1 shows the openable area 2 open and with open slots 3 ,

If the slots 3 are closed, they are like in 2 can be seen arranged on imaginary, circular and concentrically enclosing lines, the slots 3 extend in the direction of the imaginary lines. The slots are on the lines 3 spaced one behind the other. The slots are on adjacent lines 3 arranged side by side, with slots arranged side by side on adjacent lines 3 in their longitudinal direction, which is also the longitudinal direction of the lines, are offset from one another. Across the imaginary lines and the slots 3 seen there is a first slot 3a on a first line in the range of the distance between a second slot 3b and a third slot 3c on a neighboring line. Here are the slots 3 longer than the distances between the slots 3 so the first slot 3a on the first line the distance between the second slot 3b and the third slot 3c covered on the adjacent second line and across the lines and slots 3 seen ends of the second slot facing each other 3b and the third slot 3c overlaps. This makes it possible to use the slots 3 to the openings 4 expand in which the openable area 2 the fairing 1 transversely to the imaginary, in the exemplary embodiment circular lines on which the slots 3 are arranged, and thus across the slots 3 to stretch.

The imaginary lines on which the slots 3 are arranged, and / or the openable area 2 may have other shapes and arrangements than described and drawn.

The cladding points to an underside or rear side facing away from the passenger compartment 1 an actuator 5 to open and close the slots 3 and thus the openable area 2 on. In 3 and 4 , the cross sections of the openable area 2 the fairing 1 in closed ( 3 ) and open condition ( 4 ) is the actuator 5 represented with the symbol of an electromagnet. The actuator 5 is a device that is operated, for example, with electricity, compressed air or hydraulically and generates a mechanical movement. In the exemplary embodiment, a lifting rod engages 6 of the actuator 5 in the middle of the openable area 2 and moves the openable area perpendicular to its surface.

The actuator moves to open 5 the middle of the openable area 2 from the surface of the cladding 1 out into the passenger compartment, which creates the openable area 2 , as in 1 and 4 seen dome-shaped from the surface of the panel 1 bulges out. The dome-shaped arching increases the surface area of the openable area 2 , making the openable area 2 across the imaginary lines on which the slots 3 are arranged, and across the slots 3 is stretched, causing the slots 3 to the hexagonal, diamond-shaped or similarly shaped openings 4 expand.

The slots are closed 3 as in 2 and 3 to see closed and the openable area 2 forms a continuous, flat or slightly curved surface that is flush with the surface of the cladding 1 flees.

On the lifting rod 6 of the actuator 5 are on the bottom or back of the panel 1 a light source 7 , for example an LED, a microphone 8th and a speaker 9 arranged. If the openable area 2 the fairing 1 can open with the speaker 9 Acoustic signals and speech are output in the passenger compartment and with the microphone 8th Speech can be recorded from the passenger compartment. With the light source 7 is an illumination of the openable area 2 from the bottom or back, so a backlighting to the openings 4 flared slits 3 possible. Backlighting with different colors is possible, which signals, for example, a signal or voice output or a readiness to record.

As in particular in the cross section of the 3 you can see the cladding 1 outside the openable area 2 or at least in an openable area 2 surrounding area thicker than in the openable area 2 , In the openable area 2 is the disguise 1 no thicker than about 10% or 5% of a distance between two slots arranged one behind the other on an imaginary line 3 from each other.

In the exemplary embodiment, there is the cladding 1 made of plastic and is in the visible area 2 elastic to dome them as described for opening and thereby the slots 3 to the openings 4 to expand. Outside the openable area 2 is the disguise 1 so thick that it can be considered rigid.
