Between the seat (7) and the fixture (9) for the support brace (2) is an assembly of springs (10) permitting a limited tilting of the seat. The link mechanism comprising the two cross-laid guide braces (3) is so formed that the skis partly move outwards and partly are edge-positioned in relation to the ground when the seat is tilted. This occurs via joints (4,5). In order that the inactivated cross-laid braces do not affect the guiding process, they are movable in their upper fixture (6), sliding beneath the seat when the latter is tilted. |
