发明名称 Shaving head having a blade supporting member with reduced cross-sectional area
摘要 The invention relates to a shaving head ( 5 ) comprising at least two bladeshaped cutting members ( 7, 7', 7 '') each having a straight cutting edge ( 9, 9', 9 '') extending parallel to a longitudinal direction (Y) of the shaving head. Each cutting member is supported in a cartridge ( 11 ) of the shaving head by means of a supporting member ( 17 ) which supports the respective cutting member in a supported area ( 23 ) on the respective cutting member. Said supported area extends over a predetermined distance (D) perpendicular to the longitudinal direction. Each supporting member has a first portion ( 25 ) in contact with the supported area at a location remote from the cutting edge of the respective cutting member and a second portion ( 27 ) in contact with the supported area at a location near the cutting edge of the respective cutting member. The first portion has a basic cross-sectional area, seen perpendicularly to the longitudinal direction, and the second portion has a reduced cross-sectional area. According to the invention, the second portion ( 27 ) of the supporting member ( 17 ) of at least one of the cutting members ( 7, 7', 7 '') extends over at least half of said predetermined distance (D). In this manner, the free space between two adjacent cutting members is considerably increased. As a result, the rinsability of the shaving head is improved, so that the risk of shaving debris accumulation between two adjacent cutting members is reduced.
