The present disclosure relates to a method of manufacturing a stationary blade (102) and to a stationary blade (102), the method comprising providing a metal component (106), involving applying a first bending procedure, thereby forming a top wall (112) and two legs (114, 116) at opposite ends of the top wall (112) that are spaced away from one another in a longitudinal direction, wherein, subsequent to the bending procedure, each of the two legs (114, 116) is arranged at a first angle (α) with respect to the top wall (112), and wherein two bending edges (152, 154) are formed between the top wall (112) and the two legs (114, 116), providing a support insert (108) having a longitudinal extension (l.sub.s) that is at least slightly greater than a receiving space (l.sub.b) between the two bending edges (152, 154), joining the metal component (106) and the support insert (108), wherein the metal component (106) is at least slightly pretensioned due to the longitudinal extension (l.sub.s) of the support insert (108), and applying a second bending procedure to the metal component (106), comprising further bending the two legs (114, 116), thereby arranging each of the two legs (114, 116) at a second angle (*) with respect to the top wall (112) that is smaller than the first angle (α).

A hair grooming appliance includes a hair grooming device, a drive assembly, and a handle. The drive assembly is coupled to the hair grooming device and configured to drive the hair grooming device. The hair grooming device and the handle are pivotably connected at a hinge and rotate relative to each other about a pivot axis extending through the hinge between an opened position and a closed position.

A blade set for a hair cutting appliance includes a stationary blade and a cutter blade. The stationary blade has a blade base and a plurality of teeth extending from the blade base in a longitudinal direction. The teeth are arranged in a series alternating with tooth gaps therebetween, where the tooth gaps define hair entry slots. The teeth have a first side arranged to cooperate with the cutter blade to cut hair and a second side arranged as a skin-facing side. The teeth have processing edges at the first side at their longitudinal extension, where the smoothened processing edges have smoothened edge transitions.

A motion transmission unit for a drive train of a hair cutting appliance includes an input shaft, an eccentric portion, a motion converter, and a tilting lever that engages a driving portion of a blade set. The motion converter is arranged between the input shaft and the tilting lever. The eccentric portion engages a motion converter input interface. A motion converter output interface engages the tilting lever input interface and includes a cylindrical portion defining a cylinder axis parallel to a swivel axis of the tilting lever. A tilting lever output interface includes a head portion defining a cylinder axis parallel to a swivel axis of the tilting lever. The cylinder axis of the head portion and the cylinder axis of the cylindrical portion are parallel to the swivel axis.

A hair clipper is provided, including a chassis having upper and lower chassis portions defining an enclosed interior chamber, said upper and lower chassis portions configured for being secured together; and an outer housing including upper and lower housing portions constructed and arranged for enclosing the chassis as the housing portions are secured together such that the interior chamber is isolated from the housing.

An electric-powered trimmer includes a cutting assembly having a stationary blade. A moveable blade is positioned on the stationary blade such that a cutting gap is defined between the moveable blade and the stationary blade. The moveable blade is configured to move along a first axis and a second axis extending orthogonal to the first axis. An adjustment mechanism is operable to move the moveable blade along the second axis relative to the stationary blade to selectively change the size of the cutting gap.

A back and body hair cutting device has: a hair cutting part; and an elongate handle part. The handle part may be sized to permit a user to remotely manipulate the hair cutting part into contact with all areas of a back of the user. The hair cutting part may be a multidirectional cutting device, for example if the hair cutting part has a multi-directional motorized blade that is structured to define a plurality of directions of skin travel and configured to cut hair when advanced over a skin surface in each of the plurality of directions of skin travel.

The present disclosure relates to processing head (124) for a hair cutting appliance (10), the processing head (124) comprising a powered blade set (26) comprising a stationary blade (42) and a movable blade (62), wherein the movable blade (62) is arranged to be moved with respect to the stationary blade (42) to cut hair between teeth (64) of the movable blade (62) and teeth (44) of the stationary blade (42), a linkage unit (92) supporting the powered blade set (26), wherein the linkage unit (92) enables a contour following pivoting movement of the powered blade set (26) when the appliance (10) is operated to cut hair, and a razor blade (130) that is arranged to be attached to the powered blade set (26) in such a way that the powered blade set (26) and the razor blade (130) are pivotably supported by the linkage unit (92). The present disclosure further relates to a combined blade unit (126) and to a hair cutting appliance (10) that is equipped with a combined blade unit (126).

The present invention provides for a hair trimming apparatus having a pivotally attached blade cartridge with a blade that is insert-molded to a jacket and has a rear surface that is etched.
