Coated springs and mattress made thereof |
摘要 |
The invention describes a coated spring for mattresses that comprises a helical compression spring and a wrapping in the form of a bag containing the spring, wherein the bag containing the spring is injected with a polymeric reaction mixture, which after reacting or curing produces a polymeric foam, preferably of flexible polyurethane up to a desired volume in order to cause the spring to change its flexion or compression properties, as well as the method for its manufacturing and its use in the manufacturing of mattresses of different kinds. |

1. A coated spring for mattresses comprising:
a helical spring; and a bag containing the helical spring, the bag containing the helical spring further containing a flexible polymer that forms a combination with a portion of the helical spring such that the flexible polymer causes a change in the compression properties of the portion of the helical spring combined with the flexible polymer, the change in the compression properties depending on the height of the flexible polymer within the bag, the flexible polymer formed by a polymeric reaction mixture having a predetermined volume introduced into the bag. |
