Patent number: 9015886Abstract: An oral care implement is disclosed. The oral care implement includes a head section including a carrier element that is mounted for driven movement; a base section including a transmission element; and an at least partly elastically deformable neck section arranged between the head section and the base section. The transmission element is coupled to the carrier element for driving the carrier element into an oscillatory movement with an oscillation amplitude peak value. Further, the neck section is arranged as a parallel spring arrangement that deforms when a load above a first threshold load value is applied at the head section along a use direction such that the angular relationship between the head section and the base section is preserved and the head section and the base section move relatively to each other resulting in a reduction of the oscillation amplitude peak value.Type: GrantFiled: June 18, 2013Date of Patent: April 28, 2015Assignee: Braun GmbHInventor: Thomas Fritsch
