EXTERNAL CUTTING MEMBER OF A SHAVING DEVICE HAVING HAIR-GUIDING ELEMENTS WITH THICKNESS PROFILE
The invention relates to an external cutting member (19) for use in a hair-cutting unit (13a, 13b, 13c) of a shaving device (1). An annular hair-cutting track (41) of the external cutting member has a central axis (43), a plurality of hair-entry openings (49), and hair-guiding elements (51) arranged between each pair of adjacent hair-entry openings. The hair-guiding elements each comprise an outer surface segment (55), an inner surface segment (57), a first side surface (59) bounding a first hair-entry opening (49a), a second side surface (61) bounding an adjacent second hair-entry opening (49b), a first cutting edge (63) at a location where the first side surface connects to the inner surface segment, and a second cutting edge (65) at a location where the second side surface connects to the inner surface segment. In a cross-section extending perpendicularly to a radial direction with respect to the central axis, each hair-guiding element has an imaginary middle axis (79) extending perpendicularly to the inner surface segment. The imaginary middle axis intersects the inner surface segment in a point of intersection (81) half-way between the first and second cutting edges, and divides a total cross-sectional area (A.sub.T) of the hair-guiding element into a first cross-sectional area portion (A.sub.1) including the first cutting edge and a second cross-sectional area portion (A.sub.2) including the second cutting edge, the total cross-sectional area being the sum of the first and second cross-sectional area portions. According to the invention, the first cross-sectional area portion of each hair-guiding element is equal to or smaller than 48% of the total cross-sectional area of the hair-guiding element. The invention further relates to a hair-cutting unit (13a, 13b, 13c) for use in a shaving device (1), comprising an external cutting member according to the invention and an internal cutting member (21) which is rotatable relative to the external cutting member about an axis of rotation (29), wherein the internal cutting member comprises first cutting edges (69) for co-operation with the first cutting edges of the external cutting member during rotation of the internal cutting member in a first rotational direction (R1), and second cutting edges (73) for co-operation with the second cutting edges of the external cutting member during rotation of the internal cutting member in a second rotational direction (R
