Abstract (en)
The core has springs (3, 4) wound in a helical-shape and arranged adjacent to each other in an axially parallel manner, where the springs (3) comprise large spring stiffness opposite to the springs (4). The springs form spring strands (1, 2) that are arranged one behind the other in a row, and an edge reinforcement is formed at two opposite edges of the spring core through the springs (3) that are connected with the springs (4) of the adjacent spring strand. The springs are arranged in bags from a flexible material e.g. textile material, where the bags are connected with one another.
