摘要: A hair-cutting unit comprises an external cutting member (10) having a shaving surface (11) provided with hair-entry openings and a skin supporting member (30) having a skin supporting surface (31) surrounding the external cutting member (10). The hair-cutting unit is further equipped with an adjustment mechanism (50) configured to adjust an exposure distance over which the shaving surface (11) protrudes relative to the skin supporting surface (31) in an exposure direction (E). The external cutting member (10) and the skin supporting member (30) are jointly pivotal about a stationary pivot axis. The adjustment mechanism (50) is designed such that the stationary character of the pivot axis can be maintained for every possible relative position of the external cutting member (10) and the skin supporting member (30), so that a well-functioning combination of the adjustment mechanism (50) and the pivoting arrangement of the respective members (10, 30) is realized.

摘要: A transmission system (100) for use in an electric shaver comprises a first base portion (41), a second base portion (42), and a coupling arrangement (50) coupled to the respective base portions (41, 42) such as to convert a rotation of the first base portion (41) about a first rotation axis (Ar1) into a rotation of the second base portion (42) about a second rotation axis (Ar2). The coupling arrangement (50) comprises N coupling portions (51) which are each coupled to the respective base portions (41, 42), at least in a tangential direction relative to the respective rotation axis (Ar1, Ar2), wherein N is at least two. The coupling portions (51) are mutually coupled such that the coupling portions (51) are displaceable relative to each other only in an axial direction of a central axis (Ac) which extends through center points (Bc1, Bc2) of the respective base portions (41, 42).
