Patent number: 4928643Abstract: A rewind or recoil starter for an internal combustion engine which is adapted to be coupled to the engine element to be started, and which is returned to its resting position by a rewind or recoil device after manual operation of its actuating structure and after the engine has started. A safety device in the starter is provided which, in the event of an unsuccessful starting operation and upon kick-back of the engine element against the starting direction, uncouples the actuating structure of the starter from the back-kicking engine element. The starter is equipped with a driven member rigidly seated on the engine element to be started, and with a driving member which, during starting, is driven by way of the actuating structure to drive the engine element in the starting direction.Type: GrantFiled: May 10, 1989Date of Patent: May 29, 1990Assignee: Motorenfabrik Hatz GmbH & Co.
