In the first region (3a) the members are engaged in a folded position and the second region (3b) is engaged in an extended position. A section of the members has a first and/or a second guide section (21, 22). The guide sections are guided in a guide track (31) in the second region of the guidance system. The guidance system has a sorting section (33) through which the first or second guide sections can be removed from the guide track. The sorting section may have a sorting opening (33) through which the first or the second guide sections may pass. The guide sections may have different profiles.
