[0002] Seat cover device, seat device and motor vehicle

[0003] The present invention relates to a seat cover device for a seat device for a motor vehicle. Furthermore, the invention relates to a seat device for a motor vehicle. The invention also relates to a motor vehicle with a seat device.

[0004] Currently publicly available seat covers for motor vehicle seating systems generally feature connection concepts that involve connecting the seat covers to a foam device of the seat system using staples, wires, hook-and-loop fasteners, and / or clips. The known and / or previously mentioned connection concepts have the disadvantage that a large number of elements, such as wires, hook-and-loop fasteners, and / or clips, are usually foamed into the foam device of the seat system. This is detrimental to the circular economy and recyclability, as the individual components and / or the different materials can only be separated from one another with considerable time, expense, and / or effort. For example, the staple connection method involves foaming a wire into the foam device.In one corresponding cover device, for example, a fleece strip is sewn to a wire so that the staples can be hacked through the fleece strip and the wire into the foam. Consequently, this known seat device comprises several different materials that could not be used together, which would be disadvantageous. Separate them would be time-consuming, expensive, and / or labor-intensive. Alternative clips usually also involve a plastic strip sewn into the cover device, with the clips usually foamed into the foam device, which makes advantageous separation of the materials difficult or even impossible. Known hook-and-loop fastening concepts also have the problem of disadvantageous material separation.

[0005] It is therefore an object of the present invention to remedy, or at least partially remedy, the above-described disadvantages of the prior art. In particular, it is an object of the invention to provide a seat cover device for a seat device for a motor vehicle, which allows for particularly simple separation of the materials, in particular the cover device from the foam device. In particular, it is also an object of the invention to provide a seat device for a motor vehicle and a motor vehicle.

[0006] The above object is achieved by the patent claims. In particular, the object is achieved by a seat cover device having the features of independent claim 1. Furthermore, the object is achieved by a seat device having the features of independent claim 9 and by a motor vehicle having the features of independent claim 10. Further advantages and details of the invention emerge from the subclaims, the description and the drawings. Features described in connection with the seat cover device according to the invention naturally also apply in connection with the seat device according to the invention, the motor vehicle according to the invention and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is and can always be made reciprocal.

[0007] According to a first aspect of the invention, the object is achieved by a seat cover device for a seat device for a motor vehicle, the seat cover device comprising a foam device and a cover device, wherein the foam device has a plurality of connecting tunnels through the foam device, wherein the cover device has a plurality of connecting bands, each with at least one holding element, wherein the plurality of connecting bands is each connected at a first end to the cover device and is each connected at an opposite second end to the respective at least one holding element, wherein the plurality of connecting bands and the plurality of holding elements are each pluggable through one of the plurality of connecting tunnels in such a way thatthat the cover device is arranged on a first side of the foam device, and the plurality of retaining elements are arranged on an opposite second side of the foam device, wherein the cover device is releasably attachable to the foam device by the plurality of retaining elements with the plurality of connecting straps. Within the scope of the invention, the seat cover device is preferably described in use with a seat device for a motor vehicle. However, the seat cover device is of course also suitable for seat devices for alternative devices, such as trains, aircraft, boats, and / or static applications and / or devices.

[0008] The foam device is preferably to be understood as a flat foam device, in particular as a seat cushion and / or a back cushion. The foam device is designed in one piece or in multiple parts. The foam device is preferably compressed at least in sections and / or preferably has regions with different densities and / or damping properties and / or is designed in layers. The foam device preferably has a flat design in a main extension plane, such that the foam device is significantly larger in two main extension directions than in the third extension direction, orthogonal to the main extension plane. The thickness of the foam device is preferably to be understood in the third main extension direction. The foam device has a plurality of connecting tunnels through the foam device.The connecting tunnels are preferably formed along the thickness of the foam device through the foam device. The connecting tunnels are preferably understood as through holes through the foam device. The foam device preferably comprises a front side facing the cover device and / or a seat surface of the seat device, and a rear side facing away from the cover device and / or a seat surface of the seat device and / or facing a base structure of the seat device.

[0009] The cover device is preferably designed as a cover for the foam device, for the seat cover device and / or for the entire seat device. The cover device is therefore preferably to be understood as an outer shell for the foam device, for the seat cover device and / or for the entire seat device. The cover device is preferably designed three-dimensionally. The cover device preferably has a rear side which, in the assembled state, faces the foam device, and a front side which, in the assembled state, faces away from the foam device. In other words, the front side is preferably to be understood as the outer side of the cover device, wherein the outer side, in the assembled state, faces, for example, an interior of the motor vehicle.

[0010] The seat cover device is particularly advantageous because the cover device has a plurality of connecting straps, each with at least one holding element. The connecting straps are preferably attached to the back of the cover device. The connecting straps are preferably sewn, glued and / or otherwise attached to the cover device. The connecting straps are further each connected to at least one holding element, wherein the connecting straps are connected to the cover device at a first end and each connected to the respective at least one holding element at an opposite second end. In other words, the holding elements are connected to the cover device via the respective connecting strap. Within the scope of the invention, the holding elements serve to releasably attach the cover device to the foam device.For the releasable fastening, the holding elements and the connecting straps are inserted and / or pulled through the connecting tunnels. The plurality of connecting straps and the plurality of holding elements are each inserted through one of the plurality of connecting tunnels such that the cover device is arranged on a first side, preferably a front side, of the foam device and the plurality of holding elements are arranged on an opposite second side, preferably a back side, of the foam device. In an assembled state, the connecting straps therefore extend within the connecting tunnels through the foam device, wherein the cover device is preferably arranged on the front side of the foam device and the holding elements are arranged on the back side. Preferably, at least one connecting strap, in particular exactly one connecting strap, extends through each connecting tunnel.The retaining elements are particularly advantageous because they are designed for releasably securing the cover device to the foam device via the connecting straps. For illustrative purposes, the retaining devices are preferably understood as holding elements that are at least partially flat and for releasably securing the cover device to the foam device via the connecting straps. For example, the holding elements are understood as buttons that, in conjunction with the connecting straps, exert a flat holding force on the back of the foam device in order to releasably secure the cover device to the foam device.A seat cover device designed in this way is particularly advantageous since a separation of the materials, in particular the cover device from the foam device, is made particularly easy by the holding elements and the connecting straps, whereby an advantageous positioning securing and / or tensioning of the cover device on the foam device is made particularly easy until the fastening is released.

[0011] According to a preferred further development of the invention, it can be provided in a seat cover device that the plurality of connecting straps is designed to be elastic and / or is each connected to a rear side of the cover device, a piping of the cover device and / or a stitched fold of the cover device, in particular in a force-fitting and / or material-fitting manner. The connecting straps are designed to be elastic at least in sections. The cover device has a rear side which, in the assembled state, preferably faces the foam device, and a front side which, in the assembled state, preferably faces away from the foam device. In other words, the front side is preferably to be understood as the outer side of the cover device, wherein the outer side, in the assembled state, faces, for example, an interior of the motor vehicle.From the back of the cover device, the connecting straps can advantageously be inserted and / or pulled directly through the connecting tunnels, thus ensuring a favorable fit of the cover device on the foam device. Attaching the connecting straps to a piping and / or a stitched fold of the cover device enables an advantageously stable attachment and, at the same time, an advantageous design of the cover device, in particular with no or reduced perception of the connection between the cover device and the connecting straps from the front of the cover device.A seat cover device designed in this way is particularly advantageous due to the attachment of the plurality of connecting straps, since the materials, in particular the cover device, can be separated particularly easily by the holding elements and the connecting straps, wherein advantageous positioning and / or tensioning of the cover device on the foam device is particularly easily enabled until the attachment is released. According to a preferred further development of the invention, it can be provided in a seat cover device that the plurality of holding elements are each designed to be compressible at least in sections and / or to be inserted by twisting through one of the plurality of connecting tunnels of the foam device. To attach the cover device to the foam device, the holding elements are inserted or pulled through the connecting tunnels.For this purpose, it is advantageous if the retaining elements are designed to be compressible at least in sections and / or to be inserted by twisting through one of the numerous connecting tunnels of the foam device. Alternatively or additionally, the connecting tunnels in the foam device are expandable at least in sections. In the assembled, uncompressed state, the retaining elements enable a secure, detachable attachment of the cover device to the foam device through the numerous connecting straps.A seat cover device designed in this way is particularly advantageous due to the design of the holding elements, since a separation of the materials, in particular the cover device from the foam device, is made particularly easy by the holding elements and the connecting straps, whereby an advantageous positioning securing and / or tensioning of the cover device on the foam device is made particularly easy until the fastening is released.

[0012] According to a preferred further development of the invention, a seat cover device can be provided with a plurality of retaining elements each configured in a plate-shaped and / or button-shaped manner. A releasable fastening of the cover device to the foam device by means of the retaining elements and the plurality of connecting straps is particularly advantageously enabled if the retaining elements are each configured in a plate-shaped and / or button-shaped manner. Essentially, the retaining elements enable a preferably planar holding force to be exerted on the cover device by means of the plurality of connecting straps. Illustratively, the connecting straps clamp the foam device between the cover device and the retaining elements.The plate-shaped and / or button-shaped retaining elements can be advantageously inserted or pulled through the connecting tunnels, thus enabling quick and uncomplicated assembly of the cover device to the foam device. A seat cover device configured in this way is particularly advantageous due to the design of the retaining elements, since the retaining elements and the connecting straps make it particularly easy to separate the materials, in particular the cover device from the foam device, while advantageously securing the positioning and / or tensioning of the cover device to the foam device until the fastening is released.

[0013] According to a preferred further development of the invention, a seat cover device can be provided in which the cover device, the plurality of connecting straps, and the plurality of retaining elements are made from the same material group and / or the same material. Particularly advantageous recycling of the materials is enabled if the cover device, the plurality of connecting straps, and the plurality of retaining elements are made from the same material group and / or the same material. The same material group is to be understood, for example, as a plastic material group, so that, for example, the cover device, the plurality of connecting straps, and the plurality of retaining elements are made from different plastics.Alternatively or additionally, the cover device, the plurality of connecting straps, and the plurality of holding elements are made of the same material, for example, the same plastic. Further separation of the materials of the cover device, the plurality of connecting straps, and the plurality of holding elements is thus advantageously no longer necessary, and they can be recycled together, thus saving labor, time, and / or costs.A seat cover device designed in this way is particularly advantageous due to the design of the cover device, the plurality of connecting straps and the plurality of holding elements made of the same material group and / or of the same material, since a separation of the materials, in particular of the cover device from the foam device, is made particularly easy by the holding elements and the connecting straps, wherein an advantageous positioning securing and / or tensioning of the cover device on the foam device is made particularly easy until the fastening is released.

[0014] According to a preferred further development of the invention, a seat cover device can be provided with a length of the plurality of connecting straps each shorter than the length of the respective connecting tunnel, so that the cover device is releasably fastened to the foam device by the plurality of retaining elements with the plurality of connecting straps, with a tensioning force exerted by the plurality of connecting straps. A shorter length of the connecting straps in relation to the connecting tunnels enables an advantageous tensioning force of the connecting straps, in particular the elastic connecting straps, on the cover device and the respective retaining elements.A seat cover device designed in this way is particularly advantageous due to the design of the connecting straps and the foam device, since a separation of the materials, in particular of the cover device from the foam device, is made particularly easy by the holding elements and the connecting straps, whereby an advantageous positioning securing and / or tensioning of the cover device on the foam device is made particularly easy until the fastening is released.

[0015] According to a preferred further development of the invention, it can be provided in a seat cover device that the foam device comprises at least one recess for receiving at least one holding element of the plurality of holding elements and / or at least one recess channel for receiving a plurality of holding elements of the plurality of holding elements. Preferably, the at least one recess for receiving at least one holding element of the plurality of holding elements and / or the at least one recess channel for receiving a plurality of holding elements of the plurality of holding elements is configured on the rear side of the foam device. The at least one recess and / or the at least one recess channel advantageously enable the holding elements to be countersunk at least partially, in particular completely, into the foam device, thus advantageously enabling the mounting of the foam device on, for example, the seat device.By at least partially burying the retaining elements in the foam device, noise caused by contact between the retaining elements and other devices of the seat device is advantageously reduced or completely eliminated. A seat cover device configured in this way is particularly advantageous due to the design of the foam device, since the retaining elements and the connecting straps make it particularly easy to separate the materials, in particular the cover device from the foam device, while advantageously securing the positioning and / or tensioning of the cover device on the foam device until the attachment is released is particularly easy.

[0016] According to a preferred further development of the invention, it can be provided in a seat cover device that the plurality of connecting tunnels are evenly spaced from one another and / or arranged on at least one straight line, in particular on at least two parallel straight lines. A uniform and / or regular spacing of the connecting tunnels enables an advantageously flexible design of the cover device and a correspondingly flexible arrangement and fastening of the connecting straps to the cover device. The foam device and / or seat device configured in this way thus advantageously enables an at least partially modular system. For example, the same foam device with the plurality of connecting tunnels can be used for different cover devices, with different cover devices at least partially using different connecting tunnels of the foam device.A seat cover device designed in this way is particularly advantageous due to the design of the foam device, since a separation of the materials, in particular of the cover device from the foam device, is made particularly easy by the holding elements and the connecting straps, whereby an advantageous positioning securing and / or tensioning of the cover device on the foam device is made particularly easy until the fastening is released.
