Patent number: 8439006Abstract: The invention relates to a starter device which is used to start internal combustion engines, which comprises an electromagnetic toe-in mechanism (10) and a start-stop-mechanism, which in a stop-phase of the internal combustion engine, even during and/or after stopping the internal combustion engine, a positioned state of the toe-in mechanism (10) is provoked, such that when the internal combustion engine is subsequently started, it is already in the positioned state. According to the invention, a locking device (20), which is used to lock the toe-in mechanism (10) in the positioned state, is embodied in such a manner that it can be controlled such that the electromagnetic toe-in mechanism (10) is maintained in the advanced position during the stop-phase.Type: GrantFiled: October 6, 2006Date of Patent: May 14, 2013Assignee: Robert Bosch GmbHInventor: Jochen Laubender
