LOAD CARRIER FOR A MOTOR VEHICLE WITH CLAMP CONTOURS

The invention relates to a load carrier (10) for a motor vehicle (13), in particular a passenger car, with a slide guide base (11), in particular for mounting on a load carrier receptacle (22) of the motor vehicle (13), and with a slide (12) guided on the slide guide base (11), adjustable between a rest position (R) and a use position (G) along a longitudinal axis (26), wherein the slide (12) in the use position (G) protrudes beyond the slide guide base (11) further than in the rest position (R), in particular for carrying a load, wherein the slide (12) is guided on the slide guide base (11) by means of guide rails (24) on which runner rails (39) or rollers are guided. In the load carrier (10), it is provided that it has at least one clamping contour (71) associated with the rest position (R) or the use position (G) on a clamping body (61) and at least one counter-clamping contour (91, 53) cooperating with the clamping contour (71) on a counter-clamping body (90), which are arranged on the slide guide base (11) and the slide (12) and which come into engagement with one another through a movement of the slide (12) in the direction of a longitudinal position with respect to the longitudinal axis (26), in particular the rest position (R) or the use position (G), in order to clamp the slide (12) with respect to the slide guide base (11) in a clamping fit.
