Abstract
A blade unit (2) of a safety razor has a flexible blade assembly (5) comprising plurality of blades (16) with parallel cutting edges (17), mounted on a resiliently compliant support structure (4) that includes several spring elements (12) disposed along the blade unit (2) to oppose local deformation of the blade unit (2) under shaving forces imposed in the regions where the spring elements (12) act. In an embodiment the support structure (4) is a one piece moulding of resiliently flexible material and includes an upper frame (6) on which the blade assembly (5) is carried, a sub-frame (7) and a base (8), the upper frame (6) and the sub-frame (7) being connected together by a living hinge (9) and the sub-frame (7) and base (8) being connected by another living hinge (10) so that the support structure is Z-shaped in cross-section.
The support structure (4) includes two series of parallel webs (12, 14) uniformly spaced along the blade unit.
The support structure (4) includes two series of parallel webs (12, 14) uniformly spaced along the blade unit.
