Patent number: 11534282Abstract: A multi-component housing having a length and comprising at least a first component comprising a first plastic material, a second component comprising a second plastic material, and a third component comprising a third plastic material. The housing includes at least one tolerance-elimination element made of the second plastic material and longitudinally attached to the first component along the housing's longitudinal axis. The tolerance-elimination element has an average length extending parallel to the housing's longitudinal axis, which average length is at least ten times less than the length of the housing. The third component at least partially forms an outer surface of the housing, so that the tolerance-elimination element is at least partially overmolded by the third plastic material.Type: GrantFiled: February 12, 2019Date of Patent: December 27, 2022Assignee: Braun GmbHInventors: Marc Kunz, Werner Huebscher, Kris Lueckel, Sven Schäfer, Stefan Gehard Triebig
