The present invention relates to a seat storage and a chair, in particular a multi-legged restaurant or multi-function chair.

It is known from the prior art, in particular in the field of office chairs, to store the seat surface of a chair and in particular to allow pivoting and tilting movements in order to stimulate the hip of the seated person to move and in this way reduce the risk of back tension ( so-called "dynamic sitting"). However, the known from the prior art techniques for storage of the seat unit or the seating area are still in need of improvement, especially in terms of their manufacturability and on the safe support of the seating area in horizontal directions. At the same time, no solutions are yet known from the state of the art as to how these pivotable mounting of the seat known in the field of office chairs can also be used in other chairs, in particular in the gastronomy sector, in the school sector or in other fields of use of chairs, which do not have a central function Support post as an office swivel chair but have several chair legs.

Object of the present invention is therefore on the one hand to improve the seat support of a chair and on the other to provide a chair which is particularly stable and thereby a variety of applications is accessible.

These objects are achieved with a seat bearing according to claim 1 and a chair according to claim 8.

According to the invention, a seat bearing according to the present invention comprises a support shell, a bearing unit and a seat unit, wherein the support shell has a base area and an edge area, wherein the base area extends predominantly parallel to a horizontal plane, wherein the edge area projects transversely from the base area, wherein the bearing unit rests on the base portion and the seat unit relative to the support shell pivotally and elastically resiliently supported about a main bearing point, wherein the seat unit is supported in a non-deflected state predominantly or exclusively in a central storage area of the storage unit and wherein the seat unit in a deflected state additionally by at least one outer Storage area of the storage unit is supported, wherein the edge region has a greater extent parallel to the horizontal plane than the seat unit, wherein the seat unit at least in the undeflected state para llel to the horizontal plane is at least partially encompassed by the edge region.

The support shell of the seat bearing is preferably formed like a trough and has a base region which extends substantially flat and parallel to a horizontal plane, and an edge region which is substantially transverse to the base region and surrounds the base region at its edge. In this case, the transition region between the base region and the edge region is preferably rounded, which improves the transmission of force between the edge region and the base region.

The bearing unit ensures the pivotable mounting of the seat unit on the base region of the support shell. In this case, the storage unit has a central storage area, which is particularly preferably designed as an elastically resilient block or cylinder. Particularly preferably, the central storage area is provided with a rubber block on which rests the seat unit and is set so that you can perform a tumbling movement about a main bearing point by elastic deformation of the rubber block. The seat unit advantageously has a support plate and a seat cushion attached thereto. The support plate ensures sufficient stability and sufficiently strong attachment to the bearing unit or on the support shell.

The seat pad in particular increases the comfort of the user of the seat storage and includes, for example, foam and / or viscose foam and / or a textile coating. When the seat unit is deflected about the main bearing point, it comes into contact with an outer bearing area of the bearing unit.

The outer storage area of the storage unit is arranged at a distance from the central storage area of the storage unit and has, for example, a multiplicity of individual rubber elements, which are distributed around the circumference about the main storage point on the storage unit and fixed directly or indirectly to the support tray. Due to the size of the support elements of the outer bearing area and their arrangement relative to the central storage area can be particularly the amplitude of the pivoting movement and the spring characteristic, with which the seat unit springs in their maximum deflected state.

An essential feature of the present invention is that the support shell has an extension measured parallel to the horizontal plane which is greater than the extent of the seat unit measured parallel to the horizontal plane. In this case, the seat unit is inserted into the support shell such that the edge region of the support shell completely surrounds the seat unit, at least in its lower region, and thus encompasses it. It goes without saying that the Seat unit, in particular the preferred seat cushion of the seat unit, transversely to the horizontal plane, based on gravity upwardly protrudes from the support shell and the edge region of the support shell to allow a comfortable sitting of the user. At the same time, however, the seat unit is surrounded in its lower region by the edge region of the support shell such that sliding out of the seat unit in a direction parallel to the horizontal plane from the support shell is prevented. It can be significantly increased in this way, the stability of the seat storage.

In a preferred embodiment, the seat unit is fitted with a tight fit in the edge region of the support shell, so that there is always a support in the horizontal direction and yet a pivoting movement of the seat unit is possible to the main bearing point.

In a preferred embodiment, the base region and the edge region are integrally formed with each other. It is particularly preferred that the base region and the edge region are in the form of a one-piece casting, ie. H. For example, aluminum casting or plastic casting, are made together. It can be reduced in this way, on the one hand, the manufacturing cost of the support shell and on the other hand, the strength of the connection between the base area and edge area can be optimized.

Preferably, the seat unit is in the deflected state parallel to the horizontal plane from the edge region comprises. Preferably, the edge region of the support shell, the seat unit thus also includes a state in which the seat unit is deflected maximum. This means that a displacement of the seat unit in the horizontal direction, d. H. parallel to the horizontal plane, relative to the support shell is also prevented when the seat unit is deflected maximum. In the event that a user of the seat support is seated obliquely on the seat unit in such a way that it is pivoted maximally about the main bearing point, a lateral displacement or slipping out of the seat unit can be prevented. With this feature, the stability of the seat support can be significantly improved, since the seat unit in each of the intended operating conditions, ie. H. deflected state and not deflected state, is covered by the edge region of the support shell.

Preferably, the edge region is designed to support the seat unit against displacement substantially parallel to the horizontal plane. Advantageously, therefore, a close fit is provided between the seat unit and the edge area, by means of which the edge area is enabled to support the seat unit against displacement parallel to the horizontal plane. In this case, the edge region comprises at least the lower, d. H. vertically downwards facing part of the seat unit, complete, so that a support of the seat unit is ensured in each direction parallel to the horizontal plane. The stability of the seat bearing can be significantly increased with this feature. This gives the user of the seat storage a secure seating feeling, since no unexpected displacements can occur on the seat unit.

Preferably, the edge region is concavely curved in a section perpendicular to the horizontal plane in the direction of the seat unit. Particularly preferably, the concave curvature of the edge region is designed such that it is parallel to a circular path, in particular the circular path which is described by the outer edge of the seat unit in a pivoting movement about the main bearing point. In this way, the edge region always includes the seat unit with approximately the same distance, while the seat unit can perform pivotal movements between the undeflected and the deflected state. In the event that a tight fit between the edge region and the seat unit is provided as described above, thus the edge region supports the seat unit in each pivoted state against displacement parallel to the horizontal plane. In addition, by a relatively close fit between the seat unit and the edge region, the ingress of dirt particles in the region between the seat unit and the support shell can be prevented.

Advantageously, the support shell has an intermediate element, which is arranged between the seat unit and the base area, wherein at least one rib is integrally formed on the base area and / or on the intermediate element, which causes a support of the intermediate element relative to the base area. The intermediate element may preferably be formed as a plate-shaped metal part, which serves in particular to increase the strength of the support shell. Furthermore, the intermediate element can serve as an adapter element in order to be able to easily integrate into one of the same support shell and with one and the same seat unit different configurations, in particular the bearing unit, into the seat mounting. Thus, the intermediate element can in particular define the possible pivot angle of the seat unit and be set by the use of various intermediate elements at different seat supports respectively preferred maximum pivot angle. Further preferably, the intermediate element or the base region has at least one rib, which supports the intermediate element relative to the base region and thereby a Truss-like construction between the base area and the intermediate element arises. By this truss-like construction, the strength of the support shell of base area and intermediate element and edge area is significantly increased. Preferably, a multiplicity of ribs are formed on the base region and / or on the intermediate element, which can preferably engage in each case in a form-fitting manner on the opposing component on which they are not formed in one piece. In this case, in a preferred embodiment, the ribs extend essentially in a circular or elliptical or circular manner about an axis running perpendicular to the horizontal plane. This axis advantageously extends through the main bearing point, resulting in an advantageous, uniform force distribution on the inner and the outer bearing area.

Advantageously, the central storage area is set directly on the base area, wherein the outer storage area can be fixed or fixed to the intermediate element. With this embodiment, by using an intermediate element with an outer bearing area fixed thereto, as described above, a specific spring and pivoting characteristic of the seat unit can be set for a specific seat bearing. It can in this way the production costs, in particular for the production of the support shell, d. H. of the composite of basic area and edge area, be significantly reduced. The intermediate element is designed as a separate component, which can be used in a simple manner in the composite of the base region and the edge region of the support shell and preferably comes into positive engagement with the base region, the edge region and / or the intended ribs. The central storage area is preferably fixed directly to the base area, in particular by means of a screw connection, which protrudes through both the base area and the central storage area and can be fixed to an engagement area on the seat unit.

According to the invention a chair is provided, comprising a support shell, a bearing unit and a seat unit, wherein the support shell has a base region which extends predominantly parallel to a horizontal plane, wherein the bearing unit rests on the base region and the seat unit relative to the support shell pivotable about a main bearing point and elastically resiliently supported, wherein at least two chair legs are fixed to the support shell or formed integrally with the support shell, wherein the chair legs are spaced from each other and spaced from the main bearing point in a direction parallel to the horizontal plane extending direction. The chair, with its two chair legs formed or fixed thereto, is characterized by its particularly high stability and stability. In particular, the connection of chair legs directly to the support shell and an arrangement of the chair legs spaced apart such that an immediate and large-scale support of the support shell relative to the ground is ensured by the chair legs proves to be advantageous. It can thereby reduce the required wall thicknesses, both on the support shell and on the chair legs, and it can be minimized in this way the weight of the chair. Advantageously, no rotating elements or rolling elements are present between the support shell and the floor on which the chair stands, so that a particularly stable sitting on the chair with the swivel seat unit is possible. The arrangement of at least two chair legs, which are spaced from each other and at the same time from the main storage point, provides compared to chairs with a central support, as known from office chairs, a much higher stability and reduces the required strength of the individual components used. In this way, an inventive chair provides a combination of the tiltable seat unit with the high stability of a multi-legged chair with at least two, preferably three or four, to provide chair legs. Advantageously, in this case, the support shell on the features of the edge region described above, which surrounds the seat unit parallel to the horizontal plane such that a support of the seat unit against displacement is ensured parallel to the horizontal plane.

Advantageously, four chair legs are fixed to the support shell or integrally formed. This increases the stability of the chair compared to two or three chair legs, which in particular significantly increases the seating comfort of a user who exploits the pivoting movement of the seat unit. Integrally formed in the context of the present invention means that the chair legs preferably in one piece as a casting together with the support shell, d. H. the base region and the edge region, and preferably also the integrally provided on a support shell ribs is made. In this way, by means of a simple die casting process, the essential part of the chair can already be produced in a particularly short time and with particularly high strength and with little expenditure of time. Alternatively, for example, to be able to vary the length or thickness or the material of the chair legs relative to the support shell, the chair legs are preferably screwed to the support shell or set with positively engaging elements.

Further preferably, a backrest is fixed to the support shell or integrally formed. A backrest allows a further increase in seating comfort for a user of the inventive chair. The backrest, like the chair legs described above, either integrally formed in a single process step with the support shell or fixed by means of positive and / or non-positive engagement on the support shell.
