By shifting the control element on the carrier slat, the slats of the second slat arrangement can be adjusted and the control element can be adjusted to at least one adjustment position in which the slats of the first or second slat arrangement as a closing slat arrangement are adjusted in such a way that the outflow passes through the slats of the closing slat Lamella arrangement is completely closed.

From the DE 10 2017 118 450 A1 An air vent for a vehicle is known which comprises a housing, an air duct delimited by the housing with an air inlet end and an air outlet end, wherein an air flow flowing through the air duct can flow from the air inlet end to the air outlet end along a main flow direction. An outlet grille arranged at the air outlet end comprises an opening grid with grid openings spaced from one another by webs, with several air guide elements arranged in the air duct in the flow direction in front of the outlet grille forming an opening grid with grid openings which are larger than the grid openings of the outlet grille.

The invention is based on the object of providing an air outlet device for a vehicle which makes transitions between an open position that maximizes an effective cross section of an air outlet opening and a closed position that minimizes the effective cross section of the air outlet opening visually interesting for an occupant.

This object is achieved by an air discharge device for a vehicle having the features of claim 1. Advantageous configurations with expedient developments of the invention are specified in the dependent claims.

In order to provide an air discharge device for a vehicle, which transitions between an open position that maximizes an effective cross section of an air outlet opening and a closed position that minimizes the effective cross section of the air outlet opening are visually interesting for an occupant, closure elements are wave-shaped and form a lattice structure. In the open position, wave crests of a first closure element and oppositely arranged wave troughs of an adjacent second closure element enclose common grid openings, and the wave troughs of the first closure element are pivotably coupled to the wave crests of the second closure element. In the closed position, the closure elements are arranged in pairs in alignment with one another. Here, the pairs of closure elements each form a common closure surface, with common closure surfaces of adjacent pairs of closure elements running obliquely to one another.

In the following, an air discharge device for a vehicle is understood to mean an assembly which is suitable for being arranged at an end region of an air duct. The air flow here flows from a first end region of the air duct to a second end region of the air duct, the air outflow device being arranged at the second end region of the air duct can be. The air discharge device comprises a housing which forms an air outlet opening through which the air flow exits from the air duct into a vehicle interior. In addition, the housing forms an air inlet opening through which the air flow from the air duct is let into the housing. The air outlet opening can be exposed by closure elements which are movably mounted between an open position and a closed position and coupled to one another. The closure elements maximize an effective cross section of the air outlet opening in the open position and minimize the effective cross section of the air outlet opening in the closed position. The closure elements are wave-shaped. This means that the closure elements each comprise a wave-shaped closure surface, the cross section of which has a periodic sequence of wave crests and wave troughs. Here the wave crests are open downwards and the wave troughs upwards. The wave crests and troughs can be curved. Alternatively, the wave crests and wave troughs can be generated by kinks, with rectilinear partial areas running at an angle to one another. The wave crests and wave troughs can have a shape which corresponds to a triangle, rectangle, trapezoid or another suitable shape that is open on one side.

Advantageously, the grille structure of the air outlet device according to the invention looks interesting in the open position and in the closed position and, in addition to the function of an air outlet grille, can also be used as a design element in the vehicle interior, which contributes to the design of the vehicle interior. The transitions between the positions act like the unfolding or folding of an origami model. This can give the occupant the impression that the interior is of high quality and modern. In addition, the wave-shaped and movably mounted closure elements and the transitions between the positions stand out clearly from the known flat movably mounted slats or from the known rigid lattice structures, which can create a distinctive recognition feature for a vehicle model or a vehicle brand.

In an advantageous embodiment of the air discharge device according to the invention, in the closed position, design openings can be formed between the common closure surfaces of adjacent pairs of closure elements. The designed design openings are closed or sealed with respect to the air duct, so that in the closed position no air flow can flow through the design openings. In addition, in addition to the wave shape of the closure surfaces, the design openings can advantageously contribute to an attractive appearance of the at least partially closed air outlet opening.

In a further advantageous embodiment of the air discharge device according to the invention, the at least one stop element can have two legs, with the common closure surfaces of adjacent pairs of closure elements in the closed position each sealing with one edge on a corresponding leg. The design openings can be reliably sealed against the air duct by means of the legs. The angle between the legs and the length of the legs can be adapted to the dimensions and shapes of the corresponding design openings.

In a further advantageous embodiment of the air discharge device according to the invention, at least one lighting element can be arranged on the at least one stop element. The at least one lighting element can be arranged on one of the two legs or in the bend between the legs. Alternatively, at least one luminous element can be arranged on each leg. The at least one luminous element can change an effect of the lattice structure in an activated state.

In a further advantageous embodiment of the air discharge device according to the invention, the at least one light element can be activated in the closed position and deactivated in the open position. The activation of the at least one luminous element can take place automatically when the closed position is reached. The deactivation of the at least one luminous element can take place automatically when the open position is reached. Alternatively, the activation of the at least one luminous element can take place automatically when a transition into the closed position is initiated. The deactivation of at least one Luminous element can take place automatically when a transition to the open position is initiated. In the closed position, the design openings can advantageously be illuminated by the at least one light element.

In a further advantageous embodiment of the air discharge device according to the invention, two adjacent closure elements arranged centrally in the housing and forming a common closure surface can have a common central pivot axis which is movably supported in translation in the direction of the air duct and in the direction of the vehicle interior. The corresponding central closure elements are pivoted about this pivot axis during the translational movement of the central pivot axis. As a result, the central closure elements execute a superimposed movement which is composed of the translational movement of the pivot axis and the pivot movement about this pivot axis.

In a further advantageous embodiment of the air discharge device according to the invention, closure elements arranged on the edge can each be mounted pivotably about a fixed outer pivot axis. As a result, the outer closure elements only perform a pivoting movement about the corresponding outer pivot axis.

In a further advantageous embodiment of the air discharge device according to the invention, pivot axes arranged between the central pivot axis and the corresponding outer pivot axis can execute a superimposed movement. The superimposed movement of the pivot axes can correspond to an arc, for example. As a result, the corresponding locking elements between the middle locking elements and the outer locking elements execute a superimposed movement, which is composed of the superimposed movement of the corresponding pivot axes and the pivot movement about these pivot axes.

In a further advantageous embodiment of the air discharge device according to the invention, a drive can move the central pivot axis when moving into the open position in the direction of the vehicle interior. Here, the closure elements arranged in the center of the housing are forcibly moved and pivoted away from one another by the movement of the edges coupled to the central pivot axis.

In a further advantageous embodiment of the air discharge device according to the invention, the drive can move the central pivot axis in the direction of the air duct when it moves into the closed position. Here, the closure elements arranged in the center of the housing are forcibly moved by the movement of the edges coupled to the central pivot axis and pivoted towards one another.

In a further advantageous embodiment of the air discharge device according to the invention, the closure elements can be forcibly moved by the movement of the central pivot axis. Here, the closure elements coupled to the two closure elements arranged in the middle of the housing react to their pivoting movement and to their translational movement. As a result, the transitions between the open position and the closed position can only be carried out by actively moving the central pivot axis.

In a further advantageous embodiment of the air discharge device according to the invention, the housing can be mounted rotatably about an axis of rotation extending in the vertical direction of the vehicle. As a result, in the open position, an air flow emerging from the grille openings can be directed in the direction of the driver or in the direction of the passenger by rotating the housing about the axis of rotation running in the vertical direction of the vehicle.

In a further advantageous embodiment of the air discharge device according to the invention, the housing can be mounted rotatably about an axis of rotation running in a first housing direction. The first housing direction can correspond to a vehicle transverse direction when the housing is in a rest position. As a result, in the open position, an air flow emerging from the grille openings can be directed in the direction of the vehicle floor or in the direction of the vehicle headliner by rotating the housing about the axis of rotation running in the first housing direction.

In a further advantageous embodiment of the air discharge device according to the invention, an elastic material can be arranged between at least one housing wall and an opposing duct wall or an opposing receiving edge which delimits the air outlet opening. The elastic material can compensate for a distance between the housing wall and the opposite channel wall or the opposite receiving edge changed by the rotational movements of the housing and cover a corresponding gap between the housing wall and the opposite channel wall or the opposite receiving edge.
