In a spring assembly, more especially for the cushioning of seats, beds or chairs or all types, including spring legs arranged in pairs, a bridge member extending between each spring leg of a pair of the spring legs, and a connecting member disposed between adjacent spring legs pairs to connect adjacent pairs. The spring leg pairs, bridge member and connecting member may be formed from a one-piece, continuous material, said material having a plurality of bends formed therein. The bends allow the spring leg pairs to fold independently of each other when the bridge member is subjected to a force.

The invention claimed is: 1. A spring assembly for a suspension mat, the spring assembly comprising: a plurality of spring assembly units, each of said spring assembly units including a pair of spring legs and a bridge member extending between each spring leg of said pair of said spring legs; and a connecting member disposed between adjacent spring assembly units of said plurality of spring assembly units so as to connect said adjacent spring assembly units; wherein said spring leg pairs, said bridge members and said connecting members are non-releasably connected with each other and formed of a one-piece, continuous material, and wherein each of said spring assembly units includes at least three substantially angular bends formed therein; wherein said bends allow the spring leg pairs to fold independently of each other when said bridge member is subject to a force. 2. A spring assembly of claim 1, wherein said spring leg pairs, said bridge member and said connecting member form a one-piece strip of said continuous material. 3. The spring assembly of claim 1, wherein said spring assembly units include four bends. 4. The spring assembly of claim 1, wherein at least one of said bends comprise an acute angle less than 45 degrees. 5. The spring assembly of claim 1, wherein connecting members are disposed substantially parallel to each other. 6. The spring assembly of claim 1, wherein connecting members include spring-steel cross bands. 7. The spring assembly of claim 1, further comprising a joining member disposed between a plurality of connecting members. 8. The spring assembly of claim 1, further comprising a joining member disposed between a plurality of bridge members. 9. The spring assembly of claim 7, wherein said joining member is transverse to a direction of said spring leg pairs, said bridge member and said connecting member. 10. The spring assembly of claim 7, wherein said joining member is a flat member, said flat member including at least one of a mesh, a mat, and a film. 11. The spring assembly of claim 7, wherein said joining member is resilient. 12. The spring assembly of claim 1, wherein at least one of said spring legs, said bridge member, and said connecting members includes plastic. 13. The spring assembly of claim 1, wherein the suspension mat is disposed on a fixed support corresponding to a desired outline of a seat, bed or chair. 14. The spring assembly of claim 7, wherein said connecting member and said joining member forms a composite material for use in seats or vehicle seats. 15. The spring assembly of claim 14, wherein the composite material includes further parts of a vehicle seat and/or is an integral component part of the vehicle seat or parts thereof. 16. The spring assembly of claim 1, wherein connecting members and said spring legs are situated so closely adjacent each other that a flat impression is produced through the number of support points. 17. The spring assembly of claim 1, wherein overall height of the spring suspension mat is between 8 and 20 mm. 18. The spring assembly of claim 1, wherein overall height of the spring suspension mat is 10 mm. 19. Vehicle seat with a spring assembly according to claim 1. 20. A spring assembly for a suspension mat, the spring assembly comprising: a plurality of spring assembly units, each of said spring assembly units including a pair of spring legs and a bridge member extending between each spring leg of said pair of said spring legs; and a connecting member disposed between adjacent spring assembly units of said plurality of spring assembly units so as to connect said adjacent spring assembly units; wherein said spring leg pairs, said bridge members and said connecting members are non-releasably connected with each other and formed of a one-piece, continuous material, and wherein each of said spring assembly units includes at least five substantially angular bends formed therein; wherein said bends allow the spring leg pairs to fold independently of each other when said bridge member is subject to a force.
