Motor vehicle blind with ball-joint mounted sliding elements

The blind has a pulling rod (13) with a sliding unit (21) that slides with respect to a central unit to compensate variation of spacing between rails. The sliding unit has an end connected to the central unit to provide a surface section that is greater than the sliding unit, in order to authorize a compensation for clearance of parallelism between the sliding and central unit. An independent claim is also included for a motor vehicle.
