ABSTRACT:
A brush section for an electric toothbrush includes a driver, a mounting tube which receives the driver, where the driver is arranged in the direction of a longitudinal axis defined by the mounting tube, a first bristle carrier mounted for rotation about a first brush axis, a second bristle carrier mounted for rotation about a second brush axis, and a mechanism to effect coupling engagement of the driver with the first and second bristle carriers. A motion of the driver effects a rotary motion of the first bristle carrier about the first brush axis and the second bristle carrier about the second brush axis. The first and second brush axes define an approximately right angle therebetween.
