The wheelchair (1) has a pair of connection adapters (6) which are operably connected with lateral struts (5) and rear axle (9). The connection adapters has the circular arc shaped recess that corresponds to the plate thickness. A pair of seat supports (8) are received and rotatably supported in connection adapters above the lateral struts. The seat supports have the circular arc-shaped contour in the lower area. The seat supports rotate in the connection adapters so that the radial surface of circular arc-shaped contours slides on the radial surface of circular arc-shaped recesses. |
