Abstract: In the case of hair brushes the arcuately shaped bristle members of which are studded with bristles, mounted in the side walls of a housing being U-shaped in cross section, are arranged in a plurality adjacently and with a distance from one another and are pivotable by means of a slide guided in the housing below these bristle members from a position of non-use into a position of use, this pivoting into the position of use and back into the position of non-use is complicated and time-consuming.This disadvantage is eliminated in that the slide has at its longitudinal edges edge cutouts facing one another, the bristle members resting between these edge cutouts on the slide in such a manner so as to be secured against unintended pivot movement. The slide can be approached with its edge cutouts to the ends of the bristle members by sliding movement in such a manner that the bristle members, by a sliding pressure by hand on the bristles, obliquely engage in the edge cutouts in the position of non-use.
