Abstract
The stroke length in a positioner of the type having a piston rod movable through a cylinder can be preset through a continuous range of adjustment. A first detent element provided at the end of the cylinder engages another detent element positionable along the rod to limit stroke length. Spacing between the two detents is continuously adjustable by rotation of a threaded sleeve coaxial with the rod. Once installed in a recliner seat or the like, the device is secure against accidental changes in the stroke setting.
