    • The invention relates to a tensioning system for a belt or chain drive. Tensioners are known in which there are plastic friction bushes to damp oscillations where the coefficient of friction is adversely affected by temperature effects. It is the purpose of the invention to provide a tensioning system in which the friction coating retains a virtually constant frictional torque throughout its useful life. To this end, according to the invention there is a basic component (2) in which against a base (5) in the shape of a circular disc bears a friction coating (18) on which is supported a friction disc (10) which is secured against rotation by means of a shaft (7), to the tensioner (9) producing the oscillating movement.

    • A brush head for an electric toothbrush is disclosed. The brush head includes a bristle support having mounting means for the movable mounting of the bristle support and a plurality of bristle tufts arranged on the bristle support in at least one outer ring and one middle ring, the middle ring being nested within the outer ring and having a central area. The outer ring includes outer bristle tufts having an elongated tuft cross-section, which outer bristle tufts are mounted on opposing sides of the outer ring. The middle ring includes at least two middle bristle tufts that each have a cross-section that is smaller than the cross-section of the outer bristle tufts and a central area including at least one bristled section that consists of two center bristle tufts having a cross-section larger than the cross-section of the middle bristle tufts. The center bristle tufts each having an elongated, substantially kidney-shaped form that complement each other so that the bristled section of the central area has an approximately circular, oval or elliptical structure.
    • 公开了一种用于电动牙刷的刷头。 刷头包括刷毛支撑件,其具有用于可移动安装刷毛支撑件的安装装置和布置在至少一个外环和一个中间环中的刷毛支撑件上的多个刷毛簇,中间环嵌套在外环内, 有一个中心区域。 外环包括具有细长的簇绒横截面的外刷毛簇,该外刷毛簇安装在外环的相对侧上。 中间环包括至少两个中间刷毛簇,每个中间刷毛簇的横截面小于外刷毛簇的横截面,并且包括至少一个刷毛部分的中心区域,该部分由具有十字形的两个中心刷毛簇组成 大于中间刷毛簇的横截面。 中心刷毛簇各自具有细长的,基本上呈肾形的形状,彼此互补,使得中心区域的刷毛部分具有近似圆形,椭圆形或椭圆形的结构。
