Abstract (en)
[origin: WO2009047144A1] The step (1) comprises cheeks (5) which are manufactured from deep drawing sheet metal, and a tread element (22) and a deep drawn seating element (24). The arc (BO1) of the seating element (24) follows a first radius (R1) in the upper region and a second radius (R2) in the lower region, wherein the second radius (R2) is somewhat smaller than the first radius (R1). The sheet (BO1) of the seating element (24) merges smoothly at the line (ÜR) from one radius into the other radius. By way of the two radii (R1, R2), the size of the step gap between the tread element (22) and the seating element (24) of the adjacent step is independent of the position of the step gap; the step gap always remains very small, for example smaller than 2.8 mm. As a result, the risk of clothing items, sharp objects, shoes, children's fingers and so on getting jammed is reduced considerably.
