Abstract:
1. A cutting device ( 1 ) for cutting hair, having at least an upper comb blade ( 2 ), a movable lower cutter blade ( 3 ), and a coupling element ( 14 ) coupled to the lower cutter blade ( 2 ) and connectable to a driving blade element of a motor for moving the lower cutter blade ( 3 ) back and forth relative to the upper comb blade ( 3 ), said blades being provided with teeth ( 8 , 9 ) which extend transversally to the direction of movement (P) of the lower cutter blade ( 3 ), and tooth gaps ( 25 , 26 ) arranged therein, wherein the teeth ( 8 ) of the upper comb blade and the teeth ( 9 ) of the lower cutter blade ( 3 ) have contact surfaces ( 4 , 5 ) on their facing sections which are in gliding contact with each other and which, in turn, form cutting edges ( 34 , 35 ) toward lateral surfaces ( 33 , 20 ) bounding the tooth gaps ( 25 , 26 ), such that the back and forth movement (P) of the lower cutter blade ( 3 ) causes the tooth gaps ( 25 , 26 ), cooperating with each other, to form constantly changing cutting gaps ( 32 ) in which hair becomes clamped and is subsequently cut, characterized in that projections ( 17 ) of the teeth ( 9 ) of the lower cutter blade ( 3 ) project from the contact surface ( 5 ) of the lower cutter blade ( 3 ) away from said coupling element ( 14 ) beyond the tooth tips ( 10 ) of the teeth ( 8 ) of the upper comb blade ( 2 ), wherein the projections ( 17 ) project in an upward direction away from the coupling element ( 14 ).
