15. A stack of spring element arrangement, which in each case are formed into an arrangement according to claim 1, wherein in the case of spring element arrangement lying on top of one another for the connecting elements as well as the spring elements, lower sides and top sides are arranged lying on top of one another at least in sections.

Description

BRIEF DESCRIPTION

[0024] Some of the embodiments will be described in detail, with references to the following figures, wherein like designations denote like members, wherein:

[0025] FIG. 1 a schematic representation of an arrangement of spring elements for a cushion support from above and from the front;

[0026] FIG. 2 a perspective representation of the arrangement from FIG. 1 obliquely from above;

[0027] FIG. 3 a perspective representation of the arrangement from FIG. 1 obliquely from below; and

[0028] FIG. 4 a perspective representation of a stack of three arrangements with multiple spring elements stacked on top of one another.

DETAILED DESCRIPTION

[0029] FIG. 1 shows a schematic representation of an arrangement with a plurality of spring elements 1, which are connected to one another via connecting elements 2, wherein the connecting elements between the spring elements 1 are embodied in one piece and are integrally moulded to the same. The shown arrangement with the multiple spring elements 1 can for example be produced by means of injection moulding, wherein as material an elastomer, in particular a thermoplastic elastomer can be used.

[0030] FIGS. 2 and 3 show perspective representations of the arrangement of the plurality of spring elements 1 from FIG. 1 obliquely from above and obliquely from below.

[0031] The spring elements 1 each have a base 3 and a support disc 4 and spring arms 5 arranged between them. In the case of the shown embodiment, four spring arms 5 are each equidistantly arranged about the base 3. Starting out from the base 3, the spring arms 4 extend to the support disc 4, which in the case of the shown spring elements 1 is formed with four part support discs 6a, 6b, 6c, 6d. The part support discs 6a, 6b, 6c, 6d are assigned a respective spring arm 5, which individually supports the part support disc 6a, 6b, 6c, 6d.

[0032] Between the support discs 6a, 6b, 6c, 6d, separating or intermediate spaces 7a, 7b, 7c, 7d are provided, in which, when looking down on the spring elements 1 from above (see FIG. 1) the connecting elements 2 run.

[0033] In the shown embodiment, the connecting elements 2 are integrally moulded onto the respective base 3.

[0034] Looking at the spring elements 1 from above according to FIG. 1, gaps 8 run between opposite edges of the part support discs 6a, 6b, 6c, 6d on the one hand and the associated spring arm 5 on the other hand. The part support disc 6a, 6b, 6c, 6d itself is moulded onto the associated spring arms 5 via a material constriction 9, likewise integrally. The spring arm 5 leads into the part support disc 6a, 6b, 6c, 6d in a region 10, which is formed in a floor region of a U-shape.

[0035] In the shown embodiment of the arrangement with the spring elements 1, the width of the spring arms 5 tapers towards the support disc 6a, 6b, 6c, 6d.

[0036] The respective base 3 of the spring elements 1 comprises an aperture 11, which can be utilised in order to fasten the arrangement of the spring elements 1 on a support using screw and/or nail. Alternatively or complementarily, such apertures can be provided in the region of the connecting elements 2 between the spring elements 1 (not shown).

[0037] FIG. 4 shows a perspective representation of a stack 20, in the case of which three arrangements with multiple spring elements 1, which are configured corresponding to the arrangement from FIGS. 1 to 3, are stacked on top of one another. It materialises that for arrangements of spring elements 1 lying on top of one another, top and bottom side lie on top of one another in each case, both in the region of the part support disc 6a, 6b, 6c, 6d in the region of the spring arms 5 and also in the region of the connecting elements 2. The arrangement of spring elements 1 described here is thus stackable which can facilitate for example the transport. It can also be provided when forming a cushion support to utilise such a stack of arrangements of spring elements 1 for example for adjusting a certain degree of hardness of the cushion support.

[0038] Although the invention has been illustrated and described in greater detail with reference to the preferred exemplary embodiment, the invention is not limited to the examples disclosed, and further variations can be inferred by a person skilled in the art, without departing from the scope of protection of the invention.

[0039] For the sake of clarity, it is to be understood that the use of “a” or “an” throughout this application does not exclude a plurality, and “comprising” does not exclude other steps or elements.
