The invention relates to a steerable carriage comprising two runners (1, 1') from which an upwardly oriented strut (2, 2') respectively rises and between which a transversal cross member (17) extends in order to hold the runners (1, 1'). A seat part (10) is fixed to the transversal cross member and is supported on both sides of the runners (1, 1') by the rear end (13) thereof, the front ends (7, 7') of the runners being bent upwards. The transversal cross member (17) is connected to the struts (2, 2') in an articulated manner just as the front end (37) of the seat part is held on the cross member in an articulated manner in such a way that it can be rotated about the central longitudinal axis (36) thereof in the centre of the cross member (17), the seat part (10) thus being able to be tilted along the central longitudinal axis thereof (36). In order to support the rear end (13) of the seat part (10) on the runners (1, 1'), the rear end regions of the runners respectively comprise a holding element (6) inside which or on which is respectively held a counter-holding element (14, 14') arranged on its end on the rear end (13) of the seat part (10). The counter-holding elements (14, 14') are arranged on the holding elements (6) fixed to the runners (1, 1') in such a way that they can be rotated in relation to the holding elements or at least twisted thereon, whereby the end of the seat part (10) is rotatably suspended on the runners (1, 1'), at two suspension points, and the seat part is further suspended on the transversal cross member (17) in an articulated manner, at a front suspension point. |
