  • Patent number: 9770835
    Abstract: A shaving unit for a dry shaver includes at least one outer cutter and one under cutter. Driven by a motor, the outer cutter and the under cutter are movable relative to each other in an oscillatory motion. The under cutter and the outer cutter, which are biased into relative engagement by at least one spring, slide along a common contact surface. The spring is arranged in such a way that its biasing force always acts at an angle to the direction of oscillation.

  • Patent number: 9044868
    Abstract: A cutting head for an electric razor is provided. The cutting head has at least one upper blade and a lower blade associated with the upper blade, which upper and lower blades are movably supported relative to one another and can be driven accordingly by a drive device. The upper blade has a contact surface for the skin to be shaved, which contact surface is formed by a plurality of webs that are each bounded by slots. The longitudinal extent of the webs runs substantially perpendicular to a threading edge bounding the contact surface. The contact surface is designed to be concave and rises towards the threading edge, where the threading edge has an outer radius and this outer radius encloses an angle of less than 90°.

  • Patent number: 8732961
    Abstract: The invention relates to a lower cutter (4) which, together with an associated upper cutter (6), forms the shaving head of a dry shaver. The upper cutter is designed in the form of a perforated foil (6) which at least partially encloses the lower cutter (4) and is prestressed against the same. The lower cutter (4) has a plurality of spaced-apart blades having cutting edges (12, 13) in the form of strips between two peripheral regions (9, 10). The lower cutter (4) is essentially U-shaped in cross section. The width of the strip tapers monotonously from the two peripheral regions (9, 10) in the direction of the center (Z).
