Description

[0001] The invention relates to a fastening arrangement of a fan on a holding device of a seat system for a vehicle according to the preamble of patent claim 1.

[0002] Such a fastening arrangement for a fan to a holding device of a seat system for a vehicle is already known, for example, from DE 11 2006 002 186 T5. In this fastening arrangement, the fan is attached to the holding device by means of at least one fastening element. Furthermore, DE 100 10 986 A1 discloses a cushion for a vehicle seat. US 2002 / 0 067 058 A1 also discloses a cushion for a vehicle seat. Furthermore, a fan device is known from US 6 048 024 A.

[0003] The object of the present invention is to provide a fastening arrangement of the type mentioned at the outset so that a particularly stable fastening of the fan and a particularly advantageous noise behavior can be realized.

[0004] This object is achieved according to the invention by a fastening arrangement having the features of patent claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the remaining claims.

[0005] In order to further develop a fastening arrangement of the type specified in the preamble of patent claim 1 such that a particularly stable fastening of the fan and particularly advantageous noise behavior can be realized, the invention provides that the fastening element penetrates a first through-opening of a rigid plate of the holding device and a second through-opening of a support foam of the holding device, arranged in at least partial overlap with the first through-opening. The support foam is, for example, elastically deformable and significantly softer than the rigid and inherently stiff plate, which, for example, is not elastically deformable. In particular, the plate is designed, for example, as a plastic plate.The fastening element encompasses or engages behind a wall region of the support foam that at least partially delimits the second through-opening and is thus supported and fastened directly to the support foam on a rear side of the support foam facing away from the plate. This allows for particularly advantageous oscillation or vibration decoupling of the fan from the plate, so that excessive transmission of vibrations or oscillations and noise from the fan to the plate can be avoided. The support foam is, for example, part of the upholstery of the seating system, whereby the upholstery is used, for example, to ensure sufficient seating comfort. The support foam therefore has a dual function. On the one hand, the support foam is used for the upholstery in order to ensure sufficiently high seating comfort.On the other hand, the support foam is used to mount the fan in a way that is vibration-decoupled.

[0006] The plate is, for example, a spring mat, in particular a plastic spring mat, whereby the plate is, for example, a structural part of a seat structure of the seating system. If, for example, the fan were attached directly to the plate so that the fan were in direct contact with the plate, vibrations and noise would be transmitted from the fan to the plate and possibly amplified. Likewise, frequencies from any neighboring loudspeakers could be transmitted to the fan and thus lead to undesirable effects. The excessive transmission of vibrations or oscillations and noise from the fan to the plate could lead to the creation of undesirable noise, which would result in undesirable noise behavior and impair the actual comfort.However, the use of such additional coupling elements leads to increased costs, since the decoupling elements themselves require costs and additional assembly effort.

[0007] The aforementioned problems and disadvantages can now be avoided with the fastening arrangement according to the invention, since the already provided support foam is used to hold or fasten the fan. The support foam is, for example, at least indirectly, in particular directly, connected to the plate. In particular, it is conceivable for the support foam to be supported at least indirectly, in particular directly, on the plate. In this way, it is possible, for example, to connect the fan to the plate via the support foam and, at the same time, to decouple it from the plate in terms of vibration, so that at the same time a sufficiently stable fastening or mounting of the fan can be achieved.Overall, the fastening arrangement according to the invention allows for a simple and cost-effective fastening of the fan that is decoupled from structure-borne and airborne sound, and this with only a small number of parts, so that the costs, weight and installation space requirements can be kept to a particularly low level.

[0008] Furthermore, it is provided that the plate has at least one third through-opening, wherein the fan penetrates the third through-opening and is thereby directly supported on the support foam.

[0009] Further advantages, features, and details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and combinations of features mentioned above in the description, as well as 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 respective specified combinations, but also in other combinations or on their own, without departing from the scope of the invention.

[0010] The drawing shows: Fig. 1 shows a partial schematic and sectional side view of a fastening arrangement according to the invention; Fig. 2 shows a partial schematic exploded view of the fastening arrangement; and Fig. 3 a partial schematic and perspective rear view of the fastening arrangement.

[0011] In the figures, identical or functionally identical elements are provided with the same reference numerals.

[0012] Fig. 1 shows a detail in a schematic and sectional side view of a fastening arrangement 10 of a fan 12 on a holding device 14 of a seating system for a vehicle, in particular for a motor vehicle such as a passenger car. In the fully manufactured state of the vehicle, the seating system is arranged in its interior. The seating system is designed, for example, as an individual seat or vehicle seat and thus provides exactly one seat for one seat occupant. Furthermore, it is conceivable for the seating system to be designed as a bench seat, in particular as a rear bench seat, and thus provides a plurality of seats for respective seat occupants. The seating system has, for example, a seat structure, in particular with a seat frame, and upholstery, which is, for example, held on the seat frame or supported by the seat frame.The seat frame is used, for example, to attach the seating system to a vehicle body, e.g., a self-supporting body, particularly to the floor of the body. The upholstery, also known as seat padding, is used, for example, to ensure sufficient seating comfort, as the seat occupant can sit on the upholstery.

[0013] The fan 12 is designed, for example, as a radial fan and is part of a seat ventilation system, which can achieve particularly high seating comfort. For example, the fan 12 can be used to convey air, which can remove heat and / or perspiration from the respective seat occupant. Fig. 1 it can be seen that in the fastening arrangement 10 the fan 12 is held and thus fastened to the holding device 14 by means of respective fastening elements 16.

[0014] In order to be able to easily achieve a sufficiently stable attachment of the fan 12 and a particularly advantageous noise behavior, it is provided in the fastening arrangement 10 that the respective fastening element 16 penetrates a respective corresponding first through-opening 18 of a rigid and inherently stiff plate 20 of the fastening element 16 as well as a second through-opening 22 of a support foam 24 of the holding device 14, said second through-opening being arranged in at least partial overlap with the respective first through-opening 18. The support foam 24 is formed, for example, from a foam and / or is elastically deformable and, in particular, is softer than the plate 20. The respective fastening element 16 penetrates the respective through-openings 18 and 22 such that at least a respective part 26 of the respective fastening element 16 is arranged on a rear side 28 of the support foam 24 facing away from the plate 20.Furthermore, the respective fastening element 16 penetrates the through-openings 18 and 22 in such a way that the respective fastening element 16 engages behind or surrounds a respective wall region 30 of the support foam 24 which at least partially delimits the respective second through-opening 22, so that the respective fastening element 16 is supported and fastened directly to the support foam 24 via its respective part 26 on the rear side 28 of the support foam 24 facing away from the plate 20.

[0015] The respective fastening element 16 does not directly touch the plate 20, but rather the respective fastening element 16 directly touches the support foam 24 via the respective part 26. Thus, for example, the fan 12 is connected to the plate 20 via the fastening elements 16 and the support foam 24, allowing a sufficiently stable attachment of the fan 12. The support foam 24 ensures that the fan 12 is mounted in a way that is vibration- and oscillation-free, thus preventing, for example, excessive transmission of noise and vibration from the fan 12 to the plate 20.

[0016] The rigid and inherently stiff plate 20 is formed, for example, from a plastic, so that the plate 20 is designed, for example, as a plastic plate. In particular, the plate 20 can be designed as a spring mat, in particular as a plastic spring mat. The plate 20 is, for example, part of the seat structure, so that the plate 20 is, for example, a structural part of the seat structure or the seat system. Vibrations and noise emanating from the fan 12 should be prevented from being transmitted to the seat structure, since otherwise excessive vibration and noise would occur. This is prevented with the fastening arrangement 10 in such a way that the fan 12 is vibrationally decoupled from the plate 20 and thus from the seat structure by means of the support foam 24.The fastening arrangement 10 is based on the realization that a sufficiently vibration- and noise-isolated fastening of the fan 12 can be achieved particularly advantageously by fastening the fan 12 not directly to the plate 20, but directly to the support foam 24. To avoid direct contact between the fan 12 and the plate 20, the through-openings 18 are provided, in particular, as recesses or cutouts, so that the fastening elements 16 can penetrate the plate 20 without touching it.

[0017] The respective fastening element 16 is, for example, a hook and / or a locking element or a clip, which can, for example, be locked or clipped to the support foam 24. The fan 12 is arranged on a front side 32 facing away from the rear side 28 and the support foam 24. Furthermore, the fastening elements 16 are fastened to the fan 12 such that, for example, the fastening elements 16 extend from the front side 32 through the through-openings 18 and 22 to the rear side 28, in particular such that at least the parts 26 are arranged on the rear side 28. In this way, the fastening elements 16, in particular with their parts 26, can engage behind the support foam 24, such that the fan 12 is fastened directly to the support foam 24 via the fastening elements 16, and not directly to the plate 20.

[0018] Especially good in conjunction with Fig.2 shows that the plate 20 has third through-openings 34. The fan 12, in particular its housing 37, penetrates the through-openings 34 and is supported, in particular bypassing the plate 20, directly on respective wall regions 36 of the support foam 24, wherein the wall regions 36 cover the through-openings 34, in particular completely. Thus, the fan 12, in particular in the housing 37, directly touches the respective wall regions 36 at respective contact points and thus the support foam 24, in order to be able to represent a particularly stable attachment of the fan 12. The through-openings 34 are also recesses or cutouts to prevent direct contact between the fan 12 and the plate 20.

[0019] In particular, sufficient acoustic decoupling between fan 12 and plate 20 can be achieved with the fastening arrangement 10. For example, it is conceivable to close the respective through-opening 18 or 34 in the plate 20 by means of a fastening in order to ensure sufficient rigidity of the plate 20, while simultaneously maintaining the described decoupling of the fan 12 from the plate 20. Furthermore, it is conceivable to mount the fan 12 from the rear, which allows for particularly simple installation. Furthermore, fan contact surfaces can be eliminated, thus enabling a particularly cost-effective fastening of the fan 12.
