    Abstract: A hair cutting appliance, a blade set for a hair cutting appliance, and to a stationary blade for the blade set. The stationary blade includes a first wall portion arranged to serve as a skin facing wall when in operation, a second wall portion at least partially offset from the first wall portion, such that the first wall portion and the second wall portion define therebetween a guide slot arranged to receive a movable cutter blade in a defined mating manner, and at least one toothed leading edge having a plurality of teeth jointly formed by the first wall portion and the second wall portion. The stationary blade is an integrally formed metal-plastic composite stationary blade. Also discussed is a blade set including an integrated foil shaving region, along with a method for manufacturing a respective blade.

    Abstract: A cutting appliance, system, method and manufacturing process related to a blade set, a cutter and a stationary blade for the blade set. The cutter includes a main portion, such as a substantially flat main portion obtained from sheet metal material, at least one toothed leading edge protruding from the main portion. The at least one toothed leading edge includes at least two teeth and at least one scraping portion including a tapered scraper profile at least partially extending in a longitudinal direction that is perpendicular to a cutting motion direction of the cutter. The at least one scraping portion may be, in a mounted state, arranged to contact a stationary blade of the blade set at a first wall thereof to scrape off accumulated dirt and debris when the cutter and the stationary blade are moved with respect to each other when in operation.

    Abstract: The present invention relates to a hair cutting appliance (10) comprising a blade set (20), and to a blade set (20) of a hair cutting appliance (10). The blade set (20) is arranged to be moved through hair in an assumed moving direction (28) to cut hair. The blade set (20) comprises a stationary blade (22), a movable blade (24), and a lateral protecting element (56). The stationary blade (22) comprises at least one toothed cutting edge (32, 34), a lateral end (30), and a first surface (48) that is arranged, when in use for shaving purposes, as a skin-contacting surface. The movable blade (24) comprises a toothed cutting edge (32, 34). The stationary blade (22) and the movable blade (24) are arranged to be reciprocally moved with respect to each other in a cutting direction (Y) that is basically perpendicular to the assumed moving direction (28). The lateral protecting element (56) is associated with the lateral end (30), thereby defining a lateral end cap of the stationary blade (22), wherein the lateral protecting element (56) laterally shields a lateral edge (40) of the lateral end (30), such that, when in use, skin contact of the lateral edge (40) is prevented. The lateral protecting element (56) and the lateral end (30) cooperate so as to prevent hairs from being trapped therebetween. The stationary blade (22) and the movable blade (24) are at least partially made from steel, and the lateral protecting element (56) is made from plastic material. The blade set (20) configured to pivot or swivel with respect to a housing of the hair cutting appliance (10).

    Abstract: A shaving device comprises a head structure (2) and a base structure (4). The head structure (2) is configured to retain and support at least one shaving head (30A, 30B, 30C). The head structure (2) is releasably retainable on the base structure (4). The base structure (4) is free of support elements in an area of an outer circumference of the head structure (2) such that the head structure (2), when coupled to the base structure (4), is not supported in the area of its outer circumference. The head structure (2), when coupled to the base structure (4), is substantially only retained on the base structure (4) by a retaining force provided by a retaining structure of the base structure (4). When an overloading force is exerted on the head structure (2), the force is transferred to a coupling element (8) arranged in a central area (2A) of the head structure (2) such that the coupling element (8) is released from the retaining structure of the base structure (4) in order to prevent damage to the head structure (2).
