Between every two adjacent seating a retaining strap (7) is looped around the seat part (2) and the back rest part (3). Each strap (7) is fitted with a tightening buckle securing the strap on the seat or back rest and preventing it from shifting. In similar manner also the back rest straps (10) are positioned as a continuation of the seat straps (7). Seat straps and back rest strap are kept together by a connecting strap at the rear of the seat. Each seat strap (7) has two plug-in locks (15, 16) in the vicinity of the back rest for connection with the abdominal straps (17, 18). The seat straps (7) are provided with two or three press fasteners (19) by which the ends of leg loops (20, 21) are fixed to the straps. The other ends of the loops are connected to locks (31). The locks carry also the connecting elements of suspender-type straps (24, 25) terminating in plug-in locks (22, 23).</p> |
