Description

The present invention relates to an arrangement for directing an air flow. The present invention also relates to a corresponding motor vehicle.

State of the art

In vehicle and air conditioning technology it is well known that a steadily increasing traffic density puts a strain on the driver. Such loads can be reduced by a favorable design of the cockpit, which thus plays a central role in the comfort and safety perception of the vehicle occupants.

In order to relieve the driver in particular, the ventilation should create a pleasant interior climate as quickly as possible and maintain it over the long term. The state of the art therefore includes so-called personal air streams with a large field of action, which ensure direct or indirect, draft-free ventilation.

Criteria for the design of the vehicle ventilation include the amount of air brought into the passenger compartment and the achievable fanning field. The latter is achieved by means of suitable directional elements in the air outlet, which deflect the air horizontally and vertically. When designing these, the air flow to the vehicle occupants must be taken into account, paying particular attention to areas of the human body that are sensitive to pressure.

DE 10 2014 005 050 A1 relates to an air outlet nozzle for a motor vehicle, from which air at a temperature in an air conditioning system emerges, comprising a cover element. In the case of an air outlet nozzle for a motor vehicle, in which the amount of air flowing out of the air outlet nozzle corresponds to the operating state of the air conditioning system, the cover element partially covers the air outlet nozzle when the air conditioning system is regulated.

An air blowing device according to DE 11 2015 001 481 T5 has a wall section, a channel and a guide wall. The wall portion is provided with a blow outlet having an opening perimeter that extends in one direction. The duct has a first wall and a second wall opposite to the first wall, and an air passage is provided in the duct communicating with the blow outlet. The guide wall curves away from the first wall away from the second wall and is connected to an edge which provides the opening perimeter. The guide wall guides the air flowing in the air passage so that it is blown from the blow outlet in a direction from the second wall toward the first wall. The edge extends to have a shape that protrudes in a direction from the first wall toward the second wall.

US3752223A discloses an air conditioning device for a motor vehicle having an air distribution duct assembly that includes a pair of relatively slidably movable elongated ducts for distributing air to selected locations in the vehicle and using a single lever to selectively open and close air outlet openings in the duct assembly.

Disclosure of the invention

The invention provides an arrangement for directing an air flow and a motor vehicle with such an arrangement according to the independent claims.

One advantage of this solution is the possibility of saving installation space. An embodiment of the invention also ensures the same pressure conditions in all positions.

Further advantageous refinements of the invention are specified in the dependent claims.

Embodiments of the invention

The 1 and 2 illustrate by way of example the functional principle of the pedestrian flow in a luxury off-road sedan. Adjusting the air flow of the vent ( 10 ) works via two successively mounted flaps ( 11 , 12 ), which the air flow ( 20th - 1 ) split. One of the two flaps ( 11 ) divides the airflow ( 20th ) from one to two sub-channels ( 21st , 22nd - 1 ) on and the second flap ( 12 ) divides the airflow ( 20th ) into two further sub-channels.

The one from this arrangement ( 10 ) required installation space is in 2 clarified.

The 3 to 5 provide this conventional device with a new type of control arrangement ( 30th ) to direct the air flow opposite. The airflow ( 40 ) is here through a large channel directly from two linearly movable walls ( 31 , 32 ) on four individual channels ( 41 , 42 , 43 , 44 ) divided up. A synopsis of the 2 and 5 illustrates the noticeably reduced requirements for installation space in this way.
