A delivery bed has a seat part supported on raisable and lowerable side-pieces. A leg-support has side tubes which are journalled for axial movement on forwardly and rearwardly located pairs of support rollers journalled on bolts attached to the side-pieces. Mounted on the side-pieces are guide bars which present along the bottom edge surfaces thereof a plurality of circle-segmental latching recesses intended to co-act with circular latching flanges on the rearwardly located support rollers in selected latching positions. The position of the leg-support is adjusted by lifting the support and axially moving the same to a desired latching position. |
