Abstract: A machine includes a steering column assembly and a mechanical strut pivotably attached to the steering column assembly. The mechanical strut, free of pressurized gas, is positioned to tilt at least a portion of the steering column assembly about an axis. A tilt adjustment mechanism is movable to release a friction lock mechanism within the mechanical strut. The mechanical strut is telescopically movable through a continuous range of positions when the friction lock mechanism is released.

Abstract: A machine includes a seat assembly and a mechanical strut attached to the seat assembly. The mechanical strut, free of pneumatic seals, is positioned to move at least a portion of an armrest of the seat assembly along a horizontal axis. A length adjustment mechanism is movable to release a friction lock mechanism within the mechanical strut. The mechanical strut is telescopically movable through a continuous range of armrest lengths when the friction lock mechanism is released.

Abstract: A mechanical strut includes an inner tube and an outer tube configured to telescopically receive at least a portion of the inner tube. The mechanical strut also includes a friction lock mechanism having a released configuration that allows movement of a first locking member and a second locking member of the friction lock mechanism within the mechanical strut. An engaged configuration of the friction lock mechanism prevents movement of the first and second locking members within the mechanical strut. An adjustment mechanism is operably coupled to the friction lock mechanism for placing the friction lock mechanism into the released configuration, thereby releasing the first locking member from frictional engagement with an inner surface of the mechanical strut and allowing telescopic movement of the mechanical strut through a continuous range of positions.
