<p>A support unit for a module (10) on a height-varying surface contour (16) comprises a basic housing (22), in which several support elements (24) are movably driven in their longitudinal direction between a retracted position and an extracted position. Displacement units (54) can be acted on by their support elements in the direction of the extracted position, and fixing units with which the support elements can be fixed in their respective positions relative to the base housing (22). The fixing units on the support elements (24) comprise an effective clamping body which is acted on by an actuating device.</p> |
