[ description of the drawings ]

The invention and its advantages will be better understood by reading the following description, given purely by way of non-limiting example and made with reference to the accompanying drawings, in which:

figure 1 is a perspective schematic view of a ventilator comprising an assembly for a ventilator formed by a control button slidably mounted on an air guiding blade; and

figure 2 is a perspective exploded schematic view of the control button.

[ detailed description ] embodiments

The ventilator 2 of fig. 1 is configured to be mounted in a cabin of a vehicle, in particular of a motor vehicle, at an outlet of a ventilation system (not shown) such that the ventilation system leads into the cabin via the ventilator 2.

The ventilator 2 has an outlet opening 4, through which outlet opening 4 air passing through the ventilator 2 flows out.

In the following description, the words "front" and "rear" are understood with respect to the direction of flow of the air flowing out of the ventilator 2 towards the cockpit (indicated by the arrows S in fig. 1 and 2).

The ventilator has at least one blade 6 for guiding the air flow exiting the ventilator 2. The vanes 6 extend through the outlet opening 4.

The blade 6 is elongated along the extension direction E. The blade 6 has a rear edge, a front edge and two opposite faces.

Optionally, the blades 6 are orientable so as to allow the airflow exiting the ventilator 2 to be directed in a desired direction. The blades 6 are rotatably mounted in the outlet opening 4 about an axis of rotation substantially parallel to the direction of extension E.

The ventilator 2 comprises a control button 8 mounted on the blade 6.

The control buttons 8 are arranged to be gripped by a user, for example for orienting the blade 6.

The control button 8 is mounted on the blade 6 by being passed through and around the blade 6.

The control button 8 has a channel 10 running through the control button 8 from side to side and extending in the extension direction E, the channel 10 being provided for receiving the blade 6.

The channel 10 opens through two openings 12. Two openings 12 are located on two sides 14 of the control button 8. Each opening 12 is located on a respective side 14.

Each side 14 is one of the faces of the control button 8 that is visible by viewing the control button 8 along the extension direction E.

The opening 12 has a profile which substantially corresponds to the profile of the blade 6. Thus, when the vane 6 is received in the channel 10, each opening 12 is blocked by the vane 6. The interior of the control button 8 is not visible through the opening 12.

The control button 8 is formed by a first portion 16 and a second portion 18, which are distinct, the first portion 16 and the second portion 18 being configured to be assembled together along an assembly direction a (fig. 2) perpendicular to the extension direction E, by defining the passage 10 therebetween.

The first portion 16 and the second portion 18 are thus arranged to receive the blade 6 therebetween. They sandwich the blades between them. The first portion 16 and the second portion 18 are complementary so as to form the control button 8.

The assembly direction a extends from the rear edge of the blade 6 to the front edge of the blade 6.

The first part 16 is here the front part of the control button 8 for application against the front edge side of the blade 6, and the second part 18 is the rear part for application against the rear edge of the blade 6.

The first portion 16 defines a gripping portion of the control button 8, which is arranged for gripping by a user. The second portion 18 makes it possible to complete the first portion 16 so as to enclose the blade 6.

The control button 8 comprises at least one snap assembly 20 configured to mutually fix the first portion 16 and the second portion 18 by means of a snap.

Each snap assembly 20 is configured to enable the first portion 16 to merge with the second portion 18 along the assembly direction a and resist their separation along the assembly direction a once it is engaged.

Each catch assembly 20 includes a catch pawl 20 and a catch projection 24.

A snap detent 22 is protrudingly formed on one of the first and

second portions

16, 18, the snap detent 22 being configured to snap over a snap projection 24, the snap projection 24 being formed on an inner surface 26 of the other of the first and

second portions

16, 18, a cavity 28 partially defining the channel 10.

The portion of the first and

second portions

16, 24 with the snap projections have a cavity 28 partially defining the channel 10, the inner surface 26 being an inner surface of the cavity 28.

The snap claws 22 and the snap protrusions 24 are located on the first part 16 and the second part 18 such that the snap claws 22 and the snap protrusions 24 are located at a distance from the opening 12 when the

parts

16, 18 are assembled together around the blade 6 such that they are not visible in a viewing direction perpendicular to the assembly direction a.

The snap claws 22 and the snap projections 24 are not visible in a viewing direction perpendicular to the assembly direction a, except possibly through the opening 12 when the first part 16 is assembled with the second part 18 without the blade 6.

When the vanes 6 are present, the openings 12 are filled by the vanes 6 and the interior of the channel 10 is no longer visible through these openings 12.

When the

portions

16, 18 are grouped together around the blade 6, each snap combination 20 is located inside the control button 8, by being completely enclosed by the control button 8, so that the snap assembly is not visible along a viewing direction perpendicular to the assembly direction a, in particular along a transverse direction T perpendicular to the extension direction E and to the assembly direction a, and is not visible along the extension direction E, and preferably is not visible along any direction perpendicular to the assembly direction a.

The faces of the control button 8 that are visible in the viewing direction perpendicular to the assembly direction a are full (except for the openings 12 provided on the side faces 14) so that the interior of the control button 8 is not visible in the direction perpendicular to the assembly direction a.

The control button 8 herein comprises opposite first 30 and second 31 faces visible by viewing the control button 8 along the transverse direction T.

Each of the first face 30 and the second face 31 is full and has no opening into the channel 10.

The control button 8 comprises here four catch assemblies 20, the catch pawls 22 of two catch assemblies 20 being visible in fig. 2, their catch projections 24 not being visible, and the catch projections of the other two catch assemblies 20 being visible in fig. 2, their catch pawls 22 not being visible.

The snap fingers 22 of each snap assembly 20 are located on the first portion 16, while the snap protrusions 24 are formed on an inner surface 26 of a cavity 28 of the second portion 18.

In a variation, the catch pawl 22 of each catch assembly 20 is located on the second portion 18, and the catch projection 24 of each catch assembly 20 is located on the inner surface 26 of the cavity 28 of the first portion 16.

In another variation, the snap fingers 22 of at least one snap assembly 20 are located on the first portion 16 and the snap protrusions 24 are formed on an inner surface 26 of a cavity 28 provided on the second portion 18, and the snap fingers 22 of at least one snap assembly 20 are located on the second portion 18 and the snap protrusions 24 are formed on an inner surface of a cavity provided on the first portion 16.

The first and

second portions

16, 18 each have a

respective assembly edge

32, 34, the assembly edges 32, 34 abutting when the first and

second portions

16, 18 are assembled together.

Each snap jaw 22 is formed on an

assembly edge

32, 34 of the part of the first and

second parts

16, 18 carrying the snap jaw 22, for insertion in a cavity 28 oppositely arranged in the other of the first and

second parts

16, 18, in which cavity 28 a corresponding snap projection 24 is formed.

The assembly edge 32 of the first portion 16 is the rear edge of the first portion 16, and the assembly edge 34 of the second portion 18 is the front edge of the second portion 18.

In the illustrated example, the first portion 16 has two

wall portions

36, 38 arranged to receive the blade 6 therebetween, each of the catch claws 22 being protrudingly formed on one of the two

wall portions

36, 38.

The first portion 16 is configured to be applied over the leading edge of the blade 6, with each

wall portion

36, 38 passing over a respective side of the blade 6.

The second portion 18 also has spaced

walls

40, 42 arranged to receive the blade 6 therebetween, and each catch projection 24 is formed on the opposite one of the two

walls

40, 42 to the other of the two

walls

40, 42.

The second portion 18 is configured to be applied riding on the trailing edge of the blade 6, with each

wall portion

40, 42 passing through a respective side of the blade 6.

In the illustrated example, each snap projection 24 is tooth-shaped, formed on an inner surface 26 with the snap projections 24.

Each catch projection 24 has, for example, a sliding surface 44 inclined with respect to the assembly direction a, the sliding surface 44 serving to allow the catch pawl 22 to slide over the catch projection 24 when assembled, and a stop surface 46 inclined with respect to the assembly direction a, the stop surface 46 serving to prevent the first part 16 and the second part 18 from separating from each other once the catch pawl 22 is engaged with the stop surface 46.

The snap claw 22 comprises, for example, an aperture 48 for receiving the toothed snap projection 24. Due to the presence of the aperture 48, the snap claw 22 has substantially the shape of a ring.

Such a snap-on assembly 20 makes it possible to ensure a stable and reliable fixing of the first portion 16 to the second portion 18, which is advantageous for the perceived quality of the user.

As illustrated, optionally, the control button 8 comprises at least one guide assembly 50 and a guide groove 54, the guide assembly 50 comprising a protruding guide member 52 provided on one of the two

portions

16, 18, the guide groove 54 being provided on the other of the two

portions

16, 18, the protruding guide member 52 being configured to be inserted into the guide groove 54 along the assembly direction when assembled, the protruding guide member 52 cooperating with the guide groove 54 so as to guide the assembly between the

portions

16, 18 along the extension direction E.

The control button 8 comprises, for example, two guide assemblies 50. In fig. 2, only the protruding guide member 52 with the first part 16 and the corresponding guide groove 54 provided in the second part 18, and the further protruding guide member 52 with the second part 18 are visible.

When the blade 6 is orientable, the control button 8 is advantageously rotatably connected to the blade 6 about the rotation axis of the blade 6. For example, the blade 6 has a non-circular profile and the channel 10 has a corresponding cross-section that is non-circular, such that the control button 8 is rotatably connected to the blade 6 extending in the channel 10. Manipulation of the control button 8 allows the blade 6 to be oriented about the axis of rotation of the blade 6.

A single blade 6 is shown in figures 1 and 2.

Optionally, the blades 6 belong to a group of blades comprising a plurality of blades arranged parallel to each other.

In this case, optionally, the blades of the set of blades are orientable and interconnected by a synchronisation mechanism, such that a change in orientation of one blade of the set of blades can cause a corresponding change in orientation of each other blade of the set of blades.

Optionally, the control button 8 is slidably mounted along the blade 6 along the extension direction E.

This slidable mounting may allow the use of a control button 8 for controlling the orientation of one or more transverse air guide vanes extending along a transverse direction T, each transverse vane being rotatably mounted about an axis of rotation parallel to the transverse direction T.

When a set of blades extending along the transverse direction T is provided, it is located behind the set of blades extending along the extension direction E.

Optionally, the second portion 18 of the control button 8 is equipped with a connecting member 56 which makes it possible to connect the control button 8 to the transverse blades, so that the sliding of the control button 8 along the blades 6 changes the orientation of each transverse blade. The connecting member 56 connects the control button 8 to the transverse blade via a transmission mechanism (e.g. a cam mechanism, a linkage mechanism, a lever and/or a gear mechanism).

Thanks to the present invention, each snap assembly makes it possible to connect the first portion 16 with the second portion 18 in a reliable manner, while being invisible to the user along any viewing direction perpendicular to the assembly direction a.

This makes it possible to improve the appearance of the control button 8 and, consequently, the perceived quality of the user.
