Brush having resiliently retractable bristles, in particular for brushing surfaces of complex shape, such as teeth

摘要: Tufts of bristles (3) in a brush are resiliently retractable by thrusting against membrane (5) which is capable resilient spot deformation, with each tuft being independently from the other tufts brush. retracted into order to continuously match envelope surface (18) defined free ends (15) said shape be brushed (17), and matching takes place without substantial difference force applied various zones bristles.
