Description

The invention relates to a ventilation device for a vehicle.

Ventilation devices for vehicles are known in numerous variations. Today's vehicles are divided into three or four air conditioning zones, which are supplied with tempered air by the ventilation device. As a rule, such ventilation devices comprise at least one air duct arranged in an instrument panel, with which at least one air vent is fluidly connected. In vehicles with autonomous or semi-autonomous driving functions, the vehicle seats in the front area in particular can be adjusted very far back. As a result, it is difficult for the occupants in these vehicle seats to have an efficient flow against and temperature control by air currents which flow out of air vents arranged on the instrument panel. Especially when the occupants have adjusted the vehicle seats to a comfort position.

From the DE 10 2015 216 131 A1 A motor vehicle ventilation device with at least one elongated air line and at least one air register is known, which is in flow connection with the at least one air line. Here, the at least one air register is displaceable in the direction of the air line while maintaining the flow connection with the at least one air line.

From the DE 197 47 646 A1 is known an air distribution device for a vehicle, which has a plurality of heated or cooled air or fresh air leading into a vehicle interior. Here, at least one of the outlets can be changed with respect to its spatial position while maintaining its connection to an air duct.

The invention is based on the object of providing a ventilation device for a vehicle which enables an inflow and temperature control of an occupant to be carried out efficiently, regardless of a position of a corresponding vehicle seat.

This object is achieved by a ventilation device for a vehicle with the features of patent claim 1. Advantageous refinements with expedient developments of the invention are specified in the dependent claims.

In order to provide a ventilation device for a vehicle, which allows an inflow and temperature control of an occupant to flow efficiently and independently of a position of a corresponding vehicle seat, at least one length-adjustable air duct and at least one air vent fluidically connected to the air duct are provided, which are movable in a body element or an interior component is and is coupled with a seat adjustment.

As a result, the position of the at least one air vent is coupled to the current position of the vehicle seat, so that the occupant advantageously experiences an efficient flow and temperature control regardless of the position of the vehicle seat.

In an advantageous embodiment of the ventilation device, the at least one air vent can be moved through the at least one length-adjustable air duct between a starting position and an end position. Here, the starting position of the air vent can correspond to a starting position of the vehicle seat and the end position of the air vent can correspond to the end position of the vehicle seat. The at least one air vent can preferably be positively coupled at least with a longitudinal adjustment of the seat adjustment. In addition, the at least one air vent can output the air flow in the direction of a corresponding vehicle seat.

In a further advantageous embodiment of the ventilation device, the at least one length-adjustable air duct can be designed as a bellows or as a telescopic hollow body. Here, the telescopic hollow body can comprise at least two telescopic elements which can be nested inside one another. This enables an inexpensive and simple, yet stable implementation of a length-adjustable air duct, which can be easily used in different installation positions.

In a further advantageous embodiment of the ventilation device, the at least one length-adjustable air duct can be arranged in a central tunnel. Here, the center tunnel can have a longitudinal slot in which the at least one air vent can be guided in a linearly movable manner. This enables a simple and inexpensive implementation of the guidance of the air vent. Alternatively, the at least one length-adjustable air duct can be arranged in the sill area or in the vehicle floor.

In a further advantageous embodiment of the ventilation device, the at least one length-adjustable air duct can connect the at least one air vent to an air conditioner which generates a temperature-controlled air flow. For this purpose, the air conditioner can, for example, a radiator for heating and drying the air flow and Evaporators for cooling the air flow and a fan for generating the air flow.

The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or on their own, without the scope of Leaving invention. Embodiments are therefore also to be regarded and encompassed by the invention, which are not explicitly shown or explained in the figures, but which emerge from the explanations explained and can be generated by separate combinations of features.

An embodiment of the invention is shown in the drawing and is explained in more detail in the following description. In the drawing, the same reference numerals designate components or elements that perform the same or analog functions. Here show:

• 1 a schematic representation of a vehicle with an embodiment of a ventilation device according to the invention for a vehicle, wherein an outflow of the ventilation device is in a starting position;
• 2 a schematic representation of a vehicle with an embodiment of a ventilation device according to the invention for a vehicle, wherein an outflow of the ventilation device is in an end position;
• 3 a schematic representation of a length-adjustable air duct of the ventilation device according to the invention 1 or 2 when retracted; and

How from 1 to 4 can be seen, the ventilation device according to the invention 10 for a vehicle 1 in the illustrated embodiment, at least one length-adjustable air duct 12 and at least one fluidly with the air duct 12 connected air vents 14 on which is movable in a body element 8th or an interior component is held and with a seat adjustment 9.1 a vehicle seat 9 is coupled.

In 1 and 2 is in the interior 3 of the vehicle, for example, a right front vehicle seat 9 shown which is from an air vent 14 is tempered and flowed to. The air vent 14 can be adjusted through the corresponding adjustable air duct 12 between one in 1 shown starting position and one in 2 move shown end position. In the illustrated embodiment, the air vent is 14 with a longitudinal adjustment of the seat adjustment 9.1 positively coupled. That means the air vent 14 when the vehicle seat moves in the longitudinal direction of the vehicle x is moved automatically.

In the illustrated embodiment, the length-adjustable air duct connects 12 the air vent 14 with an air conditioner 7 which is in an instrument panel 5 is arranged and generates a temperature-controlled air flow. For this purpose, the air conditioner comprises a radiator for heating and drying the air flow and an evaporator for cooling the air flow, and a blower for generating the air flow. The air vent 14 gives the temperature-controlled air flow in the direction of a corresponding vehicle seat 9 out. As a result, the occupant experiences on the vehicle seat 9 Efficient flow and temperature control regardless of the position of the vehicle seat.

How from 1 and 2 further visible is the length-adjustable air duct 12 in the illustrated embodiment of the ventilation device 10 in a central tunnel 8A arranged. Here the middle tunnel 8A a longitudinal slot in which the air vent 14 is guided linearly. Additionally or alternatively, a length-adjustable air duct can be used 12 be arranged in a sill area or in a vehicle floor.

How from 3 and 4 the length-adjustable air duct is visible 12 in the illustrated embodiment as a telescopic hollow body 12A executed. The telescopic hollow body 12A comprises three telescopic elements that can be nested 12.1 , Of course, the telescopic hollow body 12A depending on an adjustment path of the air vent to be bridged 14 also more or less than three telescopic elements 12.1 include. In an alternative embodiment of the ventilation device, not shown 10 is the at least one length-adjustable air duct 12 designed as a bellows.
