A debris barrier snap fits to a tubular groove of one of the tubulars that define the annular gap in which the barrier is to be mounted. It is loosely mounted so that it can center itself in the annulus as the relatively moving members go out of a concentric arrangement. The continuous carbon fiber material used for the debris barrier has lubricious qualities to act as a bushing when the annulus shape changes due to movement of the tubulars out of a concentric relationship. An outer or inner groove on the barrier acts to trap and retain small particles that manage to advance between the barrier and the outer tubular. The snap fit is accomplished with flexible spaced apart fingers with grip surfaces to engage a groove on one of the tubulars.

A threaded leadscrew moves axially within the housing of a linear actuator. The leadscrew's movement rotates a threaded gear nut that surrounds the leadscrew. Stopping the gear nut rotation prevents leadscrew translation. The locking mechanism for selectively blocking rotation of the gear nut includes a cam mounted on the housing, which connects remotely to a user actuated handle. A lever, which mounts on the cam, has a tooth movable between adjacent teeth on the gear nut. The cam also has a blocker that engages the lever. When the cam is in the closed position, the blocker prevents the lever from moving to its released position away from the gear nut's teeth. When the cam is moved to the released position, the blocker releases the lever and allows it to move away from the gear nut. The lever has an opening that is somewhat bigger than a pin on the cam that extends into the opening. When the pin reaches one surface of the opening, it pulls the lever out of its engaged position.

A system for adjusting and dumping the position of a seat, such as a vehicle passenger or driver's seat, utilizes simultaneously translating master and slave adjustment rods to pivot the seat back frame about a pivot point. Each adjustment rod is locked in a passenger pre-set position by a corresponding locking mechanism. This preset position is "remembered" by way of a marker selectively engaged to the master adjustment rod, and is restored when the marker resides within a marker dock affixed to the locking mechanism. A user adjustment input is operable to release the two locking mechanisms and the marker from the corresponding rods so that the rods can freely translate as the passenger adjusts the angle of inclination of the seat back. When the adjustment input is released, the locking mechanisms and marker re-engage to provide the memory function for the system. A passenger operated dump input is operable to release only the locking mechanisms, but not the marker so that the pre-set angle is remembered.
