DESCRIPTION
Ventilation system for a vehicle
The present invention relates to a ventilation system for a vehicle, comprising at least one blade installed on a ventilation hole of the vehicle.
Background of the invention
The ventilation system of the vehicles comprises a plurality of ventilation holes, which allow the entry of air from the outside into the interior of the vehicle or the recirculation of air from inside the interior. These are normally ventilation holes located in the dashboard so that both driver and passenger of the front seats adjust the ventilation and / or air conditioning to your needs. In addition, there are also ventilation holes in the rear seats, normally located in the rear area of the front central glove compartment, in the imperial or roof of the vehicle, in the door panel ...
To this end, these ventilation holes are provided with a plurality of adjustable slats, which allow to regulate the degree of opening of said holes and to orient the direction of air exit. These slats are usually linked to each other, said slats being provided with a control, so that the user can manually regulate the opening of the holes and the orientation of the air outlet.
Such a system is described in EP 2 520 449 A2. In this document, each blade comprises two opposite ends that define a rotation axis, on which each blade rotates in a horizontal direction. Said opposite ends of each blade are housed in a plurality of holes in a separator. A friction element, in this case a damping sleeve, is connected to one end of a slat in order to establish a constant actuation force. Said sleeve is placed on the separator, in the outer area of the ventilation hole.
In this document, the sleeve is rectangular and is fixed by additional elements, such as protrusions. The reason for this geometry is so that it does not rotate with the rotation movement of the slats, thus preventing the sleeve from rotating with the slat and does not perform its function. Such positioning and geometry give it a behavior

referring to friction with the rotation projection not quite suitable for the present application.
Therefore, the objective of the present invention is to provide a ventilation system that allows controlling and homogenizing the force applied to the slats without the need for any additional element for the fastening of the friction element.
Description of the invention
With the ventilation system of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
The ventilation system for a vehicle according to the present invention comprises at least one blade installed on a ventilation hole of the vehicle, the at least one rotating blade being around its longitudinal axis, which can be horizontal, vertical or diagonal, where the at least one lama comprises a projection of rotation at each of its ends; a housing comprising at least two housings to accommodate the rotation projection of each of the ends of the at least one slat; and at least one friction element of the at least one slat; wherein the at least one friction element is associated with at least one rotation projection of the at least one slat, and because the at least one friction element is installed inside the at least one housing, so that the at At least one friction element is comprised between the at least one rotation projection and the at least one housing.
It is thus observed that, in an alternative way to the known state of the art, the at least one friction element is located in a space between a rotation projection and a housing housing. The drawback of the solution of the state of the art is that, the projection of the slat rubs against the silicone block only, being difficult to control the amount of effort applied on the slat. On the contrary, in the present invention, the movement of rotation of the projection is still linked and bounded indirectly in the hole of the housing, interposing the friction element. In this way it is achieved that the efforts applied by the user are homogeneous and smooth, resulting in a haptic or proper handling for the present application.
Preferably, the ventilation system comprises a plurality of slats linked to each other and a control attached to one of said slats, so that when the control is

operated, the plurality of slats are rotated together.
Thus, it can be seen that the stress control system applied to a blade by means of the friction element is usable both for ventilation systems that have a single blade, as well as a plurality of slats. In the case of having a plurality of slats, these are governed by the user by a command located, in a preferred embodiment, in the central slat of the louver assembly of the ventilation system. This command is normally a protuberance arranged longitudinally in the direction of the axis of rotation of the blade, with dimensions sufficient for the user to comfortably handle the position of the slats.
In addition, said slats can be arranged in any orientation within the vehicle, both horizontally, vertically and diagonally, its direction of rotation being indifferent to a correct control of the effort applied on the at least one slat.
Furthermore, advantageously, a friction element is associated with a single projection of rotation of the blade comprising the control. This minimizes the number of friction elements used in the ventilation system of the present invention, optimizing costs and assembly processes. In this way, the reactive effort of the rotations of the slats is controlled only in the blade operated by the user, that is the blade comprising the control.
It should be noted that, as described, the ventilation system according to the present invention may comprise at least the following combinations:
- a single slat with a single friction element;
- a single blade with two friction elements in each rotation projection located at each end of the blade;
- a plurality of slats with a single friction element at a single end of the blade provided with the control;
- a plurality of slats with two friction elements at each end of the slat provided with the control; or
- a plurality of slats with a plurality of friction elements.
According to a preferred embodiment, the at least one friction element comprises an outer flange placed on the outside of the at least one housing of the
5
10
fifteen

25

35
Case. It should be noted that the outer part means the part furthest from the center of the slat in the longitudinal direction, in an outer area, delimited by the housing, to the channel through which the ventilation system air circulates. Thus, the outer flange makes it possible to ensure that the friction element does not move in a longitudinal direction, or direction of the longitudinal axis of the blade. The flange allows the friction element to be correctly positioned during its assembly process and, together with a suitable pretension, ensures that the friction element remains in its working position.
It is important to note that this claim is the compression force suffered by the friction element due to the position it occupies between the housing and the projection of the blade. The higher this claim, the greater the effort to be made by the user to rotate the louvers of the ventilation system, due to a greater frictional force. On the contrary, the lower this claim is, the less effort will be made by the user to rotate the slats of the ventilation system. The objective is to establish an optimal claim between the components for the correct handling of the user, this constant force remaining throughout the useful life of the vehicle.
Advantageously, the at least one friction element is made of an elastic material, for example, of silicone. Said material allows an optimal control of the force applied by the user on the blade, increasing the sensitivity of softness in the haptic in the rotation of said slats. Furthermore, said at least one friction element preferably comprises a cross-section in the form of a circular crown, adapting to the geometry of the blade projection and the geometry of the housing of the housing.
The ventilation system according to the present invention provides the main advantage of controlling the blade effort without additional elements, since the friction element is already secured in the housing itself for the rotation projection.
The ventilation system according to the present invention also provides at least the following additional technical advantages:
- Material savings. The material required for the friction element of the system of the present invention to fulfill the same functionality as conventional friction elements is much smaller. The same functions and the same level of effort are achieved with much less material and consequent cost savings.

- There is one less level in the chain of tolerances to control. Specifically, the level we save is the positioning of the friction element in the housing. In addition, it should be noted that this level is especially important, since it is what allows the level of effort applied to be controlled. In addition, it is also very relevant because it is preferably a component of elastic and non-rigid material, being especially sensitive to variations in boundary conditions, such as temperatures, humidity ...
- It also allows the optimization of the useful space (or package) required by the whole ventilation system. The lateral area of ventilation systems of this type, that is, in the direction of the slats, has a very limited space. In this way, the addition of a few millimeters in a new piece (in this case of the friction element) is very scarce, since this space is not normally available. In the ventilation system of the present invention, the housing in the housing for the rotation projection is used to incorporate the friction element, not assuming a notable increase in occupied space.

Description of a preferred realization
The ventilation system for a vehicle according to the present invention is placed in a ventilation hole of the vehicle so as to be able to regulate the amount and direction of the air leaving through said ventilation hole.
The ventilation system comprises at least one blade 1, preferably a plurality of slats 1, which are rotatable with respect to its longitudinal axis A. Said longitudinal axis A

It can be vertical, horizontal or diagonal, depending on its mounting position.
Each blade 1 comprises at least one rotation projection 11 at each of its ends, each rotation projection being housed in a housing 21 of a housing 2, as can be seen in Figure 2.
The ventilation system also comprises at least one friction element 3, associated with at least one rotation projection 11. In addition, said at least one friction element 3 is installed inside the housing 21, so that the friction element 3 is placed between a rotation projection 11 and the housing 21.
According to the embodiment shown in Figure 2, the friction element 3 comprises an outer flange 31 placed on the outer part of the housing 21 of the housing 2, so that no additional element is necessary to control the effort of the blade , since the friction element 3 is already held in the housing 21 for the rotation projection 11.
Said outer flange 31 allows the friction element 3 to be positioned in its mounting position and ensures that the elastic element does not move in the longitudinal direction of the blade 1, without the use of additional elements.
Alternatively, a notch (not shown in the figures) may be provided at the lower end of the friction element 3 to ensure that this longitudinal displacement does not occur. However, said outer flange 31 shown in Figure 2 and the appropriate pretension are sufficient to ensure that the friction element 3 does not move.
Said friction element 3 is advantageously made of an elastic material, such as, for example, silicone, and comprises a cross-section in the form of a circular crown.
When the ventilation system according to the present invention comprises a plurality of slats 1, these are linked to each other and one of them comprises a knob 4, so that the user moves all the slats 1 at the same time using said knob 4 .
It should be noted that it is possible to use only the friction element 3 in one of the
5

25
two ends of the blade 1. Therefore, there are two alternatives, placing the friction element 3 only at one end of the blade 1 or at both ends.
In the case of placing it only at one end, the end without friction element 3 will be mounted with sufficient clearance directly against the housing 2.
It should be noted that for reasons of simplicity in the figures only one end of a blade mounted in its housing 21 has been represented with the friction element 3. However, the ventilation system according to the present invention may comprise at least The following combinations:
- a single slat 1 with a single friction element 3;
- a single slat 1 with two friction elements 4 on each projection of rotation 11;
- a plurality of slats 1 with a single friction element 3 in the blade 1 provided with the control 4;
- a plurality of slats 1 with two friction elements 3, but only in the blade 1 provided with the control 4; or
- a plurality of slats 1 with a plurality of friction elements 3.
Although reference has been made to a specific embodiment of the invention, it is evident to one skilled in the art that the described ventilation system is susceptible to numerous variations and modifications, and that all the mentioned details can be substituted by others technically equivalent, without departing from the scope of protection defined by the appended claims.
