ABSTRACT:
The invention relates to a shaving device which comprises a shaving head (1) having at least one cutting blade (5) and two skin-supporting members (11, 13), said cutting blade comprising a cutting edge (7) extending perpendicularly to a shaving direction (X) of the shaving head, and 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 (17) between the shaving head and a skin surface (53) to be treated. The cutting blade and the skin-supporting members are mounted to a sub-frame (9), which is coupled to a main frame (19) and can be displaced with respect to said main frame against a spring force (FS).According to the invention, the main frame comprises two further skin-supporting members (21, 23) 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 (FC) between the skin surface and the skin-supporting members of the sub-frame and hence a skin curvature (w2) 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 (FP) exerted by a user to press the shaving head against the skin surface.
