Brush section for an electric toothbrush
First Claim
1. A brush section for an electric toothbrush, comprising:
- a shaft;
a mounting tube in which the shaft is received and is mounted so as to be rotary about a longitudinal axis;
a bristle supporting structure which is arranged so as to be rotary about a transverse axis and is coupled to the shaft such that a rotational motion of the shaft about the longitudinal axis effects a rotational motion of the bristle supporting structure about the transverse axis (; and
a coupling mechanism which effects an additional pivotal motion of the bristle supporting structure about the longitudinal axis.

Abstract
The invention is directed to a brush section (1) for an electric toothbrush which includes a mounting tube (2) in which a shaft (7) is received which is mounted so as to be rotary about a longitudinal axis (3) and is adapted to be driven in an oscillatory fashion. Further, the brush section (1) includes a bristle supporting structure (11) which is arranged so as to be rotary about a transverse axis (14) by means of a bearing pin (18) and is adapted to be set in a rotational motion (29) about said transverse axis (14) by means of a drive pin (24). The fixed connection between the bearing pin (18) and the shaft (7) has the added effect of causing the bristle supporting structure (11) to perform a pivotal motion (28) about the longitudinal axis (3). The rotational motion (29) of the bristle supporting structure (11) produces a cleaning action on a user'"'"'s exposed tooth surfaces, whilst the pivotal motion (28) acts to accomplish an additional cleansing operation on the user'"'"'s inter-proximal surfaces.
