Abstract
Description
[0001] The invention relates to a seat cushion for a seating device of a motor vehicle, comprising at least one central seat cushion region, a first lateral seat cushion region, and a second lateral seat cushion region, wherein the central seat cushion region is at least partially surrounded by the first lateral seat cushion region and the second lateral seat cushion region, and comprising a ventilation device formed on the central seat cushion region. Furthermore, the invention relates to a seating device comprising at least one seat cushion according to the preceding aspect and to a motor vehicle having a seating device.
[0002] Seating devices, for example for a driver's seat in a motor vehicle or a front passenger seat in a motor vehicle, are already known in the prior art. These are often designed in two parts, consisting of a seat element and a backrest. Massage functions and ventilation functions, in particular active ventilation functions via ventilation devices, are already known to increase the comfort of a person in the seating device. Furthermore, it is already known that such a seating device often has corresponding side areas, for example to support a person when cornering. There is a need, in particular, to mechanically separate the side areas from the main parts of the seat. In particular, there is therefore a need for separate side parts, for example, to be able to be arranged on the seating element.
[0003] The object of the present invention is to provide a seat cushion for a seating device of a motor vehicle, a seating device and a motor vehicle, by means of which an increase in comfort for an occupant or a person can be realized.
[0004] This object is achieved by a seat cushion, a seating device, and a motor vehicle according to the independent patent claims. Advantageous embodiments are specified in the subclaims.
[0005] One aspect of the invention relates to a seat cushion for a seating device of a motor vehicle, having at least one central seat cushion region, a first lateral seat cushion region and a second lateral seat cushion region, wherein the central seat cushion region is at least partially surrounded by the first lateral seat cushion region and the second lateral seat cushion region, and having a ventilation device formed on the central seat cushion region.
[0006] It is provided that the central seat cushion region, the first lateral seat cushion region and the second lateral seat cushion region are each separate elements, wherein the first lateral seat cushion region has at least one first ventilation channel, the second lateral seat cushion region has at least one second ventilation channel and the central seat cushion region has at least one third ventilation channel, wherein the at least three ventilation channels are supplied with air by means of the ventilation device.
[0007] In particular, it is thus provided that only one ventilation device is provided in the central seat cushion area, which, however, can supply both the central seat cushion area and the two side seat cushion areas with appropriate air. Thus, separate seat cushion elements can be provided, which, however, can be ventilated via only one ventilation device. In particular, this can increase the comfort of a person using the seat cushion, since ventilation can be provided by all three seat cushion elements. In particular, lateral ventilation can also be provided.
[0008] According to an advantageous embodiment, the three seat cushion areas are formed, at least in part, from foam. In particular, the seat cushion areas can be formed from foam produced by extrusion. This allows a person to use the seating device comfortably.
[0009] A further advantageous embodiment provides for an air supply from the ventilation device to be formed on an underside of the seat cushion to the air channels. In particular, a ventilation layer can thus be provided on the underside of the seat cushion. The air supply thus originates from the underside of the seat cushion, whereby the underside can be considered the underside, particularly when the seat device is in the installed state in the motor vehicle. This allows for convenient air supply to the seat cushion.
[0010] It is also advantageous if the lateral seat cushion regions at least partially overlap with the central seat cushion region on an underside of the seat cushion. In this case, it can further be provided that respective air supply elements are formed in an overlapping region of the seat cushions, so that the air supply is formed from the central seat cushion region to the lateral seat cushion regions. In particular, the seat cushions thus have an overlapping region at the corresponding air channels, whereby air can be supplied from the central seat cushion to the two lateral seat cushion regions in the overlapping region. In this way, a strong mechanical connection can be realized between the seat cushion elements at the overlapping region, and at the same time the air supply can be carried out via the overlapping region.
[0011] A further advantageous embodiment provides that the ventilation device has at least one fan. In particular, the ventilation device can also have at least two or more fans. For example, air can be fed from an outer side of the seat cushion into the seat cushion, particularly into the seat cushion areas, via the fans. Thus, a supply of fresh air from outside can increase comfort for the occupant.
[0012] Furthermore, it has proven advantageous if the seat cushion is designed as a backrest and / or as a seat element. In particular, a seat device has at least one backrest, which is arranged, in particular, pivotably on the seat element. Seat ventilation can be provided, in particular, for both the backrest and the seat element. This allows for increased comfort for a person in the motor vehicle.
[0013] According to a further advantageous embodiment, the seat cushion has a pressed nonwoven fabric on the underside of the seat cushion. The pressed nonwoven fabric serves, in particular, as a barrier layer, so that the supplied air cannot escape from the underside of the seat cushion. This allows for a reliable air supply, particularly on the upper side of the seat cushion.
[0014] A further aspect of the invention relates to a seat device for a motor vehicle with at least one seat cushion according to the preceding aspect.
[0015] Furthermore, the invention also relates to a motor vehicle with a seating device according to the preceding aspect.
[0016] Advantageous designs of the seat cushion are to be regarded as advantageous designs of the seating device and of the motor vehicle.
[0017] Further advantages, features, and details of the invention will become apparent from the following description of preferred embodiments 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.
