Title
(EN) RAZOR WITH CONVEX BLADE ASSEMBLY
(FR) RASOIR AVEC ENSEMBLE DE LAMES CONVEXES
Abstract
(EN)
A blade assembly (10) for use in a razor has at least one blade (12) providing a cutting edge (14), a leading skin guide (16) located ahead of the cutting edge, and a trailing skin guide (18) located behind the cutting edge (14). The leading and trailing skin guides are configured to provide one or more front contact surfaces (20) and one or more rear contact surfaces (22). These front and rear contact surfaces lie substantially on a virtual convexly-curved contact profile such that, when the blade assembly is pressed against the skin of a user, the skin becomes stretched to conform to the contact profile.
(FR)
L'invention concerne un ensemble de lames (10) prévu pour être utilisé dans un rasoir qui comporte au moins une lame (12) constituant un bord de coupe (14), un guide de peau de tête (16) placé en avant du bord de coupe, et un guide de peau arrière (18) placé derrière le bord de coupe (14). Ces guides sont configurés pour constituer une ou plusieurs surfaces de contact (20) et une ou plusieurs surfaces de contact arrière (22). Ces surfaces de contact avant et arrière se situent sensiblement sur un profil de contact incurvé dans le sens convexe de telle sorte que lorsque l'ensemble de lames est comprimé contre la peau d'un utilisateur, la peau s'étire pour s'adapter au profil de contact.
