Abstract

An arrangement of spring elements for a cushion support is provided, having a plurality of spring elements, at which between a base and a support disc spring arms are arranged in each case, wherein the spring elements are arranged lying next to one another in such a manner that the support discs of the plurality of spring elements jointly define a support area and connecting elements are interconnected via the spring elements in such a manner that the spring elements are fixed in their position relative to one another, wherein the connecting elements are formed in one piece and are integrally molded onto the spring elements. The application furthermore includes a stack of spring element arrangements.

Claims (20)

1. An arrangement of spring elements for a cushion support, comprising:

a plurality of spring elements, at which between a base and a support disc, a plurality of spring arms are arranged in each case, wherein the plurality of spring elements are arranged lying next to one another in such a manner that the support discs of the plurality of spring elements jointly define a support area; and

a plurality of connecting elements, via which the plurality of spring elements are interconnected in such a manner that the plurality of spring elements are fixed in a position relative to one another;

wherein the plurality of connecting elements are formed in one piece and are integrally moulded onto the plurality of spring elements;

wherein the plurality of connecting elements form a grid structure comprising first connecting elements extending in a first direction and second connecting elements different from the first connecting elements and extending in a second direction transverse to the first direction;

wherein the support disc of the plurality of spring elements are formed in each case with a plurality of separate part support discs, which are separated from one another via intermediate spaces;

wherein, when looking down on the support discs from above, the first connecting elements run in first intermediate spaces extending in the first direction and the second connecting elements run in second intermediate spaces extending in the second direction transverse to the first directions;

wherein, when the arrangement is stacked, lower sides of the plurality of connecting elements of an upper arrangement rest on top sides of the plurality of connecting elements of a lower arrangement, and lower sides of the plurality of spring elements of the upper arrangement rest on top sides of the plurality of spring elements of the lower arrangement.

2. The arrangement according to claim 1 , wherein the plurality of connecting elements are moulded onto the plurality of spring elements at the base and/or in a section of the plurality of spring arms that is adjacent to the base.

3. The arrangement according to claim 1 , wherein the plurality of connecting elements, looking down on the support disc from above, run in the intermediate spaces.

4. The arrangement according to claim 1 , wherein the plurality of separate part support discs are arranged on one or multiple spring arms which are individually assigned exclusively to the respective part support disc.

5. The arrangement according to claim 1 , wherein looking down on the support discs from above the plurality of separate part support discs extend laterally along the spring arm or the spring arms supporting the part support disc.

6. The arrangement according to claim 1 , wherein the plurality of separate part support discs looking down on the support disc from above have a U-shape at least at an inner edge.

7. The arrangement according to claim 1 , wherein looking down on the spring elements arranged lying next to one another from above, the plurality of connecting elements and the spring elements are formed free of overlap.

8. The arrangement according to claim 7 , wherein looking down from above, gaps are formed between opposite edges in a region of a spring element with substantially the same gap width.

9. The arrangement according to claim 1 , wherein the plurality of connecting elements run according to a rectangular grid.

10. The arrangement according to claim 1 , wherein at the spring elements distal ends, which are arranged at ends which are proximal relative to the base and are located radially outside, couple to the support disc.

11. The arrangement according to claim 1 , wherein the spring arms open into the support disc via a constriction.

12. The arrangement according to claim 1 , wherein in longitudinal direction and/or in transverse direction at least two spring elements are arranged lying next to one another and connected via the plurality of connecting elements.

13. A stack of spring elements formed into an arrangement according to claim 1 , wherein lower sides and top sides of the spring elements and the plurality of connecting elements, respectively, are lying on top of one another.
