The present invention relates to a stair step nosing (1) that comprises a functional member (2) made of a resilient material as well as a horizontal fixation member (4) and a vertical fixation member (3) which are connected to the rear (6) and lower (5) surfaces of said functional member (2), respectively. The thickness H of the working member and the elasticity module E of the resilient material are determined by the relations H > h + h1 and EH x k, where h represents the thickness of step nosing material in meters, h1 represents the thickness of the horizontal fixation member in meters, and k = 1011 in n/m3.
Cette invention concerne un nez-de-marche pour marches d'escalier (1), lequel comprend un élément de travail (2) fait d'un matériau élastique, ainsi qu'un élément de fixation horizontal (4) et un élément de fixation vertical (3) qui sont reliés, respectivement, aux surfaces arrière (6) et inférieure (5) dudit élément de travail (2). L'épaisseur H de l'élément de travail et le module d'élasticité E du matériau élastique sont fonction des relations H > h + h¿1? et E?H x k, où h représente l'épaisseur du matériau dont est fait le nez-de-marche pour escalier en mètres, h¿1? représente l'épaisseur de l'élément de fixation horizontal en mètres, et k = 10?11¿ en n/m?3¿.
