ABSTRACT:
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. The safety device includes a fixedly mounted, spring-loaded decoupler pawl which does not affect the driving engagement between the driven member and the manually operated driving member when the elements of the starter are in their resting positions and during their starting movement, whereas, upon kick-back of the engine element to be started, the decoupler pawl is brought into a decoupling position by an element which then kicks back, and thereby releases the driving engagement.
