Abstract
Discloses a bristle head oscillation mechanism for an electrically driven toothbrush. A toothbrush bristle head is rotatably disposed at an end of an elongate housing. A drive shaft is rotatably disposed in the elongate housing and has an offset end coupled to one end of a pivot arm. The other end of the pivot arm is coupled to the toothbrush bristle head. Rotation of the drive shaft pivots the pivot arm to effect oscillation of the bristle head with respect to the elongate housing.
