Abstract

L'invention concerne une unité à lames (2) de rasoir de sûreté, comportant un ensemble de lames (5) constitué par une pluralité de lames (16) parallèles montées sur un manche (1) de rasoir au moyen d'une structure de support (4) flexible. Chaque lame (16) est de forme allongée et comporte une partie de bord avant (50), pourvue d'un bord coupant (17) acéré, et une partie de lame plane (54), s'étendant vers l'arrière à partir de la partie de bord avant (50). La partie de bord avant est inclinée vers le haut par courbure d'une ébauche de lame entre des outils de presse de sorte que, dans la zone de transition entre la partie de bord avant, qui s'étend vers l'arrière à partir de l'extrémité du bord coupant (17) sur 1 mm maximum, et la partie de lame plane (54), la surface inférieure soit convexe et la surface supérieure soit concave, le plan (Pt), qui constitue la bissectrice passant par l'extrémité du bord, formant un angle compris entre 10 et 35· avec le plan central (Pm) de la partie plane (54). La lame (16) est placée dans l'unité à lames (2) de sorte que le plan central (Pm) de la partie plane soit parallèle à un plan tangent, tangentiel aux surfaces de l'élément de protection (26) et du capuchon (24) de l'unité à lames. L'extrémité du bord coupant est à une hauteur comprise entre 0,05 et 0,15 mm au-dessus du plan (Pn) de la surface supérieure de la partie plane. Enfin, pour assurer une bonne flexibilité, la section transversale de la lame présente un second moment d'inertie minimum qui ne dépasse pas 1,0 x 10?-4¿ mm?4¿.
