Abstract (en)
Coil spring assemblies are disclosed comprising a plurality of coil springs (12) enclosed in a fabric (11). The coil springs (12) at a first end have a greater diameter than at a second end. In an embodiment, all the coil springs (12) are orientated substantially in the same direction, and connections (13) along slanted connection lines with respect to the longitudinal axes (17) of the coil springs are provided to enclose the coil springs (12) in individual pockets. In another embodiment, adjacent coil springs are orientated in an anitparallel manner to form an "up and down effect".
