    • The step support (17) or plate support comprises a rear crossmember (22) and a front crossmember (24) which together form a plane (E3) for receiving the tread element (9). There are two outer step cheeks (20.1, 20.2), wherein one of the step cheeks (20.1) is arranged on the right and one of the step cheeks (20.2) is arranged on the left, substantially perpendicular with respect to the crossmembers (22, 24). The two crossmembers (22, 24) are manufactured from deep-drawing sheet metal and are welded or joined or riveted or screwed or adhesively bonded or clinched to the step cheeks (20.1, 20.2) or plate cheeks to form a load-hearing frame. The height (H2) of the crossmembers (22, 24) at its ends is smaller than the height (H3) of the crossmembers (22, 24) in the center, with the result that the crossmembers (22, 24) have a curved shape.
