<p>The padding consists of first thin supporting layer (2) madeof standard flexible material having great wear- andbreaking-resistance which has elongated basic form and is used asa strong supporting part, and of a considerably thinner secondlayer (3) fixed or integrated to layer (2) which consists ofporous or puffy soft material forming the mattress part (3). Thelatter is divided in several elongated parts (5, 6, 7) by mean oflongitudinal slots (4, 4'). Parts (5, 6, 7) are connected to eachother by supporting layer (2) in sections (8, 8'), forminglongitudinal lines for folding enabling the folding of the paddingin a packet form where the two side parts (6, 7) are foldedinwards to the middle part (5), and the supporting layers (2) ofthe respective side mattress parts (6, 7) are turned one againstthe other.10 claims, 14 figures</p> |
