Abstract
A shaving device which comprises a shaving head ( ) having at least one cutting blade ( ) and two skin-supporting members ( ), said skin-supporting members, viewed in the shaving direction, being arranged, respectively, in front of and behind said cutting blade, and defining a contact surface ( ) between the shaving head and a skin surface ( ) to be treated. The cutting blade and the skin-supporting members are mounted to a sub-frame ( ), which is coupled to a main frame ( ) and can be displaced with respect to said main frame against a spring force (F ). The main frame comprises two further skin-supporting members ( ) which, viewed in the shaving direction, are arranged, respectively, in front of and behind the sub-frame and extend substantially in said contact surface. As a result, a contact force (F ) between the skin surface and the skin-supporting members of the sub-frame and hence a skin curvature (&ohgr; ) between the skin-supporting members of the sub-frame, i.e. at the location of the cutting member, is mainly determined by the value of said spring force and, accordingly, substantially independent of a pressure force (F ) exerted by a user to press the shaving head against the skin surface.
