Boarding aid or access facility has drive means which has a drive element (10) and which is designed as chain or belt. The drive element is guided by a deflection pulley (35) which is arranged below movement path and a drive roller (9) which is coupled with drive motor (11) and arranged in area of end profile (5) and in a rear area of frame (3). The drive roller has a larger diameter than the deflection pulley and thus is arranged in the interior defined from the frame. The drive mean projects partially in a covered backward extension of the movement path and a pressure roller (39) acting from outside on an upper branch (10a) of the drive element is attached to the drive roller in such a way that the upper branch is arranged in an area lying between drive mean and the deflection pulley parallel to the movement path below the movement path and below its covered backward extension. |
