First Claim
Patent Images
1. An electric toothbrush comprising:
- a brush section and a rotatably carried shaft received in said brush section, said brush section including a bristle supporting structure coupled to the shaft for motion about an axis perpendicular to an axis of rotation of the shaft, andan interproximal brush coupled to the shaft for motion about the axis of rotation of the shaft, wherein the coupling of the interproximal brush to the shaft is configured such that the motion of the interproximal brush follows an arc of rotation.

Abstract
The invention is directed to an interproximal brush for an electric toothbrush which is coupled to the shaft driving the bristle supporting structure in an alternating motion in a manner independent of the coupling of the bristle supporting structure to the shaft. The interproximal brush performs a pivotal motion enabling additional cleaning in particular of interproximal spaces.
