Abstract: The invention concerns the fields of vehicle engineering and sporting goods. It relates to a sled, preferably with two parallel interspaced runners, with spring suspension. The seat frame (5) and the runner frame (2, 3, 11 to 14) can be collapsed in a vertical direction when the sled is not in use. The seat frame (5), together with the sitting surface (18), is mounted in a rotational and detachable manner, via both of its front ends (6, 7), on the front traverse (4) of the runner frame by means of two half-shells provided with quick-release latches (8). The runners (2, 3) are, approximately at mid-length, joined in a fixed manner to the seat frame and to the sitting surface by two upward sloping rods or tubes (10, 11) and (12, 13) and by a transverse member (14), to which the longitudinal bars are fastened in a fixed manner, said rods or tubes being fastened to the runners in a fixed manner The traverse (4) forms, together with the runners and with the rods or tubes, the whole of the runner frame.
