    • 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.
    • 本发明涉及一种剃须头(5),其包括至少两个叶片形切割构件(7,7',7“),每个切割构件具有平行于纵向方向(Y)延伸的直的切割边缘(9,9',9”), 的剃须头。 每个切割构件通过支撑构件(17)支撑在剃削头的盒(11)中,支撑构件支撑相应切割构件在相应切割构件上的支撑区域(23)中。 所述支撑区域在与纵向方向垂直的预定距离(D)上延伸。 每个支撑构件具有在远离相应切割构件的切割边缘的位置处与被支撑区域接触的第一部分(25)和在靠近切割边缘的切割边缘附近的位置与支撑区域接触的第二部分(27) 相应的切割构件。 第一部分具有垂直于纵向方向观察的基本横截面积,并且第二部分具有减小的横截面面积。 根据本发明,至少一个切割构件(7,7',7“)的支撑构件(17)的第二部分(27)延伸超过所述预定距离(D)的至少一半,在此 两个相邻的切割构件之间的自由空间大大增加,因此改善了剃须头的冲洗性,从而减少了两个相邻的切割构件之间的碎屑堆积的危险。
