Description

The invention relates to a cover device for a seat substructure of a vehicle seat, the cover device laterally surrounding the lower seat part. The invention also relates to a vehicle seat, comprising a seat part, a backrest, and a seat substructure, which extends along a height axis Z is arranged under the seat part, the seat substructure being completely enclosed laterally by a cover device.

Vehicle seats are designed in particular in commercial vehicles in such a way that they are arranged so that they can swing both in the vertical direction and, if necessary, in the horizontal direction. This is necessary to dampen the person using the vehicle seat on uneven ground. For this purpose, commercial vehicle seats of this type often have a seat substructure underneath the seat part which comprises a support frame in the form of a scissor frame. If necessary, (air) spring and / or damping elements are provided in order to dampen or cushion the scissor arms in their upward and downward movement. Accordingly, the seat part will constantly change in its height direction in relation to a body floor of, for example, a commercial vehicle cabin. This happens not only while driving, but also when the driver or front passenger is at a standstill when the seat height is initially adjusted.

The seat substructure is usually covered by means of a covering device. This is done on the one hand for optical reasons, on the other hand the elements of the seat substructure are to be protected from soiling or damage. In addition, it should be prevented that the user could possibly injure himself on the elements of the seat substructure.

So far, bellows have been used as cover devices, which are made of elastic, preferably rubber-like material, which fold up and down together and again to accommodate the height movement when the vehicle seat is vibrating and thus a permanent cover to the outside of the scissor arms and to enable air spring and damper elements if necessary. However, such bellows often do not have a corresponding durability or stability.

The object of the present invention is to provide a cover device which solves the problems mentioned. A further object of the invention is to provide a vehicle seat which solves the problems mentioned.

The object is achieved by the subjects of independent claims 1 and 9. Advantageous refinements can be found in the subclaims.

An essential point of the invention is to provide a cover device for a seat substructure of a vehicle seat, the cover device laterally surrounding the seat substructure, the cover device comprising at least two inherently rigid frame-like elements, which along a height axis Z are telescopically displaceable into one another, with at least one guide device being provided, by means of which the frame-like elements are displaced along a height axis Z are performed, wherein at least one elastic element is provided, by means of which the cover device can be reset to a predetermined initial state, wherein the elastic element is connected to at least one frame-like element.

Due to the inherently rigid frame-like elements, the covering device is significantly more stable than the previously used bellows. Mechanical influences from the outside can be effectively prevented by such inherently rigid, ie non-elastic, frame-like elements. Furthermore, such stable elements effectively prevent the user from being injured by the seat substructure. Finally, the frame-like elements can be better provided with optical elements such as paintwork, which improves the visual appearance of the entire vehicle seat.

The cover device and the vehicle seat extend along a height axis Z a latitude axis Y and a depth axis X .

The guide device only allows the frame-like elements to be displaced relative to one another along the height axis Z . A shift relative to each other along the latitude axis Y and the depth axis X is prevented by the guide in the guide device. This prevents the frame-like elements from tilting, which means that they can be shifted easily along the height axis Z is made possible.

According to the invention, the covering device comprises at least two inherently rigid frame-like elements. These frame-like elements preferably have a rectangular or square base. However, it would also be conceivable for the frame-like elements to have a base area in the form of any desired polygon, an ellipse or a circle. The expression “telescopically displaceable into one another” is to be understood to mean that the frame-like elements have different dimensions, for example side lengths, diameters, etc., so that a second frame-like element can be arranged within a first frame-like element. An advantageous third frame-like element could then be arranged within the second frame-like element.

The heights are advantageously along the height axis Z of the frame-like elements are the same for each of the frame-like elements. Alternatively, the heights can be along the height axis Z of the frame-like elements may be different for each of the frame-like elements.

The seat substructure is preferably arranged on a seat part of the vehicle seat. It is also preferred that the seat substructure is arranged directly on the vehicle body or on a foot element. The foot element is advantageously arranged on the vehicle body. This can be a fixed connection or a rail system that allows the vehicle seat to be moved along the rail system.

The cover device advantageously extends from an underside of the seat part to the surface of the vehicle body or to the foot part. If a foot part is provided, this can advantageously be arranged within the covering device. Alternatively, the cover device can be on the foot part or along the height axis Z be arranged over the foot part. The height of the covering device accordingly advantageously corresponds to the distance between the seat part and the surface of the vehicle body. Alternatively, the height of the covering device corresponds to the distance between the seat part and the foot part.

Due to the design of the cover device according to the invention in the form of the telescopic design, the height of the cover device is variable.

The return according to the invention to the initial state can mean a return to an initial height of the covering device. Alternatively or cumulatively, the initial state can include the arrangement of the frame-like elements with respect to one another.

The starting height of the covering device is preferably determined from the distance between the seat part and the vehicle body or between the seat part and the foot part. It is advantageous if this distance can preferably be adjusted by a seat height adjustment device. The starting height of the cover device is preferably determined by the distance between the seat part and the vehicle body or between the seat part and the foot part in a state in which a person is in the seat.

If vertical forces now act on the seat, which are generated, for example, by vertical vibrations while driving, the distance between the seat part and the vehicle body or the foot part varies. The spring and / or damping device is used to transfer the seat part back into a corresponding vertical starting position. In this vertical starting position of the seat part, which is predetermined for the spring and / or damping device, the cover device advantageously assumes its starting height.

The cover device according to the invention can advantageously be varied in its height and accordingly adapts to the distance between the seat part and the surface of the vehicle body or the foot part. The height of the covering device is preferably changed by shifting the frame-like elements along the height axis Z . The height of the covering device is preferably reduced by pushing the frame-like elements together or one inside the other. The height of the covering device is preferably increased by pulling the frame-like elements apart.

Due to the force of the elastic element, due to its compression or expansion, the covering device can advantageously be returned to its initial state or its initial height. Furthermore, the force action of the elastic element can reset an original arrangement of the frame-like elements relative to one another.

According to a preferred embodiment, the covering device comprises at least three inherently rigid frame-like elements. According to a further preferred embodiment, the covering device comprises three inherently rigid frame-like elements.

The covering device preferably comprises one along the height axis Z uppermost and one along the height axis Z lowest frame-like element.

The uppermost frame-like element would therefore follow the movements of the seat part. The lowermost frame-like element is advantageously in contact with the foot part or against the surface of the vehicle body. It would also be conceivable if the lowermost frame-like element is in contact with or can be arranged on a foot part of the vehicle seat or on a surface of the vehicle body. It would also be conceivable for the lowermost frame-like element to be fixed on the foot part of the vehicle seat or on a surface of the vehicle body. The lowermost frame-like element would therefore follow the movements of the foot part of the vehicle seat or the surface of the vehicle body. By changing the distance between the seat part and the foot part or the surface of the vehicle body, the distance between the top and bottom frame-like elements is changed accordingly.

An upper edge of the middle frame-like element is advantageously arranged within the uppermost frame-like element in such a way that it is arranged in a middle region, advantageously essentially in the middle, along the height of the uppermost element. This has the advantage that the middle element is along the height axis Z can still be shifted in both directions relative to the top element. In other words, there is still a residual displacement path in both directions. It is also advantageous if a lower edge of the middle frame-like element is arranged within the lowermost frame-like element in such a way that it is arranged in a middle area, advantageously essentially in the middle, along the height of the lowermost element. This also has the advantage that the middle element is along the height axis Z can still be shifted in both directions relative to the lowest element. The middle area is advantageously defined by the height adjustment of the vehicle seat.

Of course, the functionality described can also be applied analogously to cover devices with more than three frame-like elements. Here again a top and a bottom frame-like element would be provided. Furthermore, several middle elements would be provided here. which are connected to at least one elastic element. It would be conceivable that an elastic element is provided for each middle frame-like element. However, it would also be possible for several middle frame-like elements to be connected to one elastic element. Even in the embodiments described below, the functionality is not limited to three frame-like elements. The embodiments can also be applied analogously to cover devices with more than three frame-like elements.

According to a preferred embodiment, the at least one elastic element is arranged on the middle frame-like element by means of at least one form-fitting and / or force-fitting connection.

The peg-shaped element can advantageously have a circumferential groove into which a corresponding projection of the receptacle engages. This ensures a stable / firm connection between the connecting element and the receptacle. The connecting element and the elastic element are advantageously made of the same material. However, it would also be conceivable that the two elements consist of different materials.

Due to the advantageous connection of the at least one elastic element with the middle frame-like element, the arrangement of the middle element can be set back relative to the top and bottom frame-like element in such a way that its top and bottom edge are in the corresponding middle areas of the top and bottom frame-like element is located.

According to a further preferred embodiment, the at least one elastic element is designed at least in sections in the manner of a plate.

In an advantageous embodiment of the cover device with an elliptical or circular base area, it is preferred if two elastic elements are arranged diametrically opposite one another.

According to a further preferred embodiment, the at least one elastic element extends along the height axis Z so that a lower edge of the elastic element can contact a foot part or a surface of the body and / or an upper edge of the elastic element can contact the seat part. A deformation force is advantageously along the height axis Z can be introduced into the elastic element through the seat part and / or the foot part of the vehicle seat or the surface of the vehicle body. Such a deformation force can advantageously be introduced directly through a force fit or form fit between the elastic element and the seat part or the foot part or the surface of the vehicle body. A form fit can be, for example, a plug connection, a screw connection, a snap connection, a clamp connection or the like. Such a deformation force leads to compression or expansion of the elastic element.

When the initial height is reduced by an application of force caused by vibrations in the vehicle seat, the frame-like elements are shifted into one another or pulled apart accordingly. Furthermore, due to the force fit and / or form fit of the elastic element with the foot part / the surface of the body and / or the seat part, the latter is compressed or stretched. As a result of this compression or expansion, the middle element, which is connected to it, is advantageously displaced upwards or downwards, so that the relative position of the middle element to the top and bottom is adapted. The preferred provision of two elastic elements each on an opposite / diametrical inner side of the frame-like element prevents the middle frame-like element from becoming tilted in the event of a corresponding displacement.

According to a further preferred embodiment, the at least one elastic element is with the one along the height axis Z uppermost frame-like element connected. According to a further advantageous embodiment, the elastic element is with the along the height axis Z lowest frame-like element connected.

The connection between the at least one elastic element and the lowest and / or uppermost element is preferably a form-fitting connection, for example a screw connection, a rivet connection, a clamp connection, a plug connection or a clip connection. Furthermore, the connection can be formed by means of connecting pins which are introduced into corresponding bores in the elements. These connecting pins can be introduced or clamped into the bores in such a way that they can be detached again.

According to a further preferred embodiment, the at least one elastic element has a first section which is designed like a plate. The elastic element preferably has a second section which has a Z-shaped cross section and along the height axis Z is arranged above the first section.

The third section advantageously merges into the first section. The at least one elastic element is preferably connected to the uppermost frame-like element by means of the second section. The elastic element is preferably connected to the lowermost frame-like element by means of the third section. The preferred form-fitting connection between the elastic element and the lowest or uppermost frame-like element is accordingly provided for the upper or lower section of the elastic element.

In this embodiment, too, when the initial height is reduced by an application of force which is caused by vibrations in the seat of the vehicle, the frame-like elements are correspondingly shifted into one another or pulled apart. By connecting the elastic element to the frame-like elements, it is compressed or stretched accordingly. As a result, a corresponding initial position in the form of an initial height of the covering device and / or an arrangement of the frame-like elements relative to one another can be restored. By the preferred provision of two elastic elements on an opposite / diametrical inner side of the frame-like elements, the middle frame-like element is prevented from being misaligned during a corresponding displacement.

Furthermore, the uppermost frame-like element ( 4th , 4a ) a larger dimension, i.e. larger side lengths, than the middle frame-like element ( 4th , 4c ), whereby the middle frame-like element ( 4th , 4c ) within the uppermost frame-like element ( 4th , 4a ) can be arranged. The middle frame-like element ( 4th , 4c ) has a larger dimension, i.e. larger side lengths, than the lowest frame-like element ( 4th , 4b ), whereby the lowest frame-like element ( 4th , 4b ) within the middle frame-like element ( 4th , 4b ) can be arranged. This results in a telescopic change in height of the covering device.

In the embodiments according to 1 to 15th the cover device extends ( 2 ) from an underside of the seat part ( 7th ) to the foot part ( 8th ). So the height is ( 25th ) the cover device ( 2 ) the distance between the seat part ( 7th ) and the foot part ( 8th ). A minimum height of the cover device ( 2 ) thus corresponds to a minimum height of the seat substructure ( 3 ), which corresponds to a complete deflection. Such a complete deflection includes a so-called stop, at which a further displacement of the scissors frame is no longer possible. Analogously, a maximum height corresponds to that of the covering device ( 2 ) a maximum height of the seat substructure ( 3 ).

The middle frame-like element ( 4th , 4c ) has a top border ( 26th ) on. The lowest frame-like element ( 4th , 4b ) an upper margin ( 27 ) on.

Likewise, in a possible starting position, the upper edge ( 27 ) of the lowest frame-like element ( 4th , 4b ) in a middle area or essentially in the middle within the middle frame-like element ( 4th , 4c ) arranged. This is for example in 7th or in 14th shown. This has the advantage that the middle frame-like element ( 4th , 4c ) along the height axis Z in both directions (up and down) still relative to the uppermost frame-like element ( 4th , 4a ) or the lowest frame-like element ( 4th , 4b ) along the height axis Z in both directions (up and down) still relative to the middle frame-like element ( 4th , 4c ) can be relocated. In other words, there is still a residual displacement path in both directions (up and down) for the respective frame-like element ( 4th , 4b , 4c ) available. This middle range can of course be varied accordingly by adjusting the height.

The guide device ( 5 ) includes a slide mount ( 17th ) in the form of a groove or a rail and a guide element ( 18th ), which is in or on the slide mount ( 17th ) is guided in the form of a groove or a rail.
