Shaving device with improved contour following

摘要

A shaving head includes at least one cutting unit in which an external cutting member is subjected to a shaving action. The external cutting member is suspended relative to a holder of the shaving head through suspension means. The suspension means includes at least two pivot constructions, wherein one pivot construction enables a member of the suspension means to be pivotable relative to the holder. The other pivot construction enables the external cutting member to be pivotable relative to the suspension member. Furthermore, a pivoting stiffness of a connection of the latter pivot construction is lower than a pivoting stiffness of the first pivot construction. In this manner, good contour following performance is obtained at two levels, in both relatively small and relatively large curvature changing areas.

主权项

1. A shaving head for use in a shaving device for removing hairs from skin by cutting through the hairs, said shaving head comprising at least one cutting unit and a holder for holding the at least one cutting unit, said holder being adapted to be mounted on a body portion of the shaving device, said body portion being configured for holding by a user of the shaving device and being adapted for accommodating various members of the shaving device;
wherein the at least one cutting unit comprises an external cutting member having a surface configured for contacting skin during a shaving action and having openings for allowing hairs to pass; wherein the at least one cutting unit further comprises an internal cutting member, said internal cutting member being drivable for movement along the openings in the surface of the external cutting member and being adapted to cut through hairs during such movement; wherein the holder is adapted to allow for rotational movements with respect to said body portion about a tilting axis; and wherein the external cutting member is suspended relative to the holder through a suspension assembly comprising: a first suspension member being tiltable with respect to the holder about a tilting axis (c), the tilting axis (c) extending into a central area of the at least one cutting unit at a side of the at least one cutting unit, said side being proximal to a central axis of the shaving head; and a second suspension member being tiltable with respect to the first suspension member about a tilting axis (d), wherein said tilting axis (d) extends in a direction relative to said tilting axis (c) for tilting cooperatively with said first suspension member and into said central area of the at least one cutting unit.
