Abstract

Hair brush with an array of bristles which are fastened on a flexible pad of bristles which yields during combing so that the position and/or location of the bristles is changed as a result, the bristles being composed of plastic, wherein the pad of bristle and the bristles are composed of a single piece and wherein the pad of bristles has the configuration of a flexible membrane.

First claim

The invention claimed is:

1. A hair brush, comprising:
a brush handle;
a bristle carrier attached to the brush handle; and
an array of bristles fastened on a flexible pad which yields during combing such that a position and/or location of the bristles change(s) as a result, wherein the bristles are composed of plastic, the pad and the bristles are composed from a single piece, and the pad is a flexible membrane that is macroscopically corrugated in itself, wherein the bristle carrier has a circumferential frame with a membrane receiving window.

2. The hair brush according to claim 1 , wherein the membrane generally has two main surfaces, the bristles protrude from at least one of these main surfaces and a sum of a surface area of the main surfaces is substantially larger than a sum of a surface area of auxiliary surfaces which connect the two main surfaces of the membrane.

3. The hair brush according to claim 2 , wherein a thickness of the membrane perpendicular to the surface of its main surfaces is between 0.25 mm and 1.25 mm.

4. The hair brush according to claim 1 , wherein the membrane has at least one slit.

5. The hair brush according to claim 4 , wherein edges of the membrane, which form edges of a slit, do not contact, even in the case of a membrane not under tension.

6. The hair brush according to claim 4 , wherein edges of the at least one slit are corrugated in a direction perpendicular to a main surface of the membrane.

7. The hair brush according to claim 1 , wherein the membrane has a continuous circumferential edge.

8. The hair brush according to claim 1 , wherein the membrane is macroscopically corrugated in itself and the corrugation forms a regular wave pattern.

9. The hair brush according to claim 1 , wherein the bristles protrude from the membrane in such a manner that their tips converge when the membrane is not under tension.

10. The hair brush according to claim 1 , wherein the bristle carrier forms a transition into the brush handle and the membrane receiving window is configured such that the membrane can be fixed in the membrane receiving window in such a manner that the membrane has a convex or spherical curvature on a side from which its bristles exit.

11. The hair brush according to claim 10 , wherein the bristle carrier has a body, and the membrane receiving window fully penetrates through the body of the bristle carrier.

12. A pad of bristles, comprising a plurality of the bristles composed of plastic, wherein the pad of bristles is a flexible membrane that is macroscopically corrugated in itself and is not glued or welded to a bristle carrier, and the pad of bristles is designed for insertion into a bristle carrier, wherein the pad of bristles and the bristles are composed from a single piece, and the bristle carrier has a circumferential frame with a membrane receiving window.
