The spacers are made of a sheet, which is made of substance, fleece material and/or a film, where the spacers are formed in a strip or ribbon-shape. The spacers run through the latter spring. The spacers are formed in a hood-shaped or sleeve-shaped manner and pulled over the latter spring, where the springs are integrally made of a wire. The spacers are made of resilient material.</p> |
