Abstract:
A safety razor blade unit having at least one blade including a blade edge for shaving, said blade being mounted for independent movement relative to other skin contacting parts of the blade unit under forces exerted at the blade edge during shaving, said blade unit defining a tangent plane which is a plane tangent to the blade edge and the surface of the skin contacting part next in front of the blade, said blade defining a tangent angle which is the angle at which the central plane of the blade intersects the tangent plane, wherein said blade is mounted to move to increase the blade tangent angle in response to load forces exerted on the blade during shaving,wherein the blade unit includes a frame, and said blade is fixedly carried on a blade support, and the blade support is connected to the frame by means defining a fulcrum, the movement of the blade comprising angular displacement about said fulcrum, and the fulcrum being located closer to the blade edge than is the point where the tangent plane meets the skin contacting surface next in front of the blade, andwherein the blade support has a suspension arm engaged with a support bar fixed to the frame and having opposite edges about which the suspension arm pivots sequentially as the angular displacement of the blade increases.
