Lumbar support screw actuator

摘要

An actuator for manipulating a bowden cable assembly of a lumbar support structure includes a housing having a longitudinal passage and a screw coupled to a cable and operable for moving in the housing passage. A threaded nut is operable for rotating and moving the screw through the housing passage. A barrel is configured for receiving the bowden cable assembly and is operable for providing movement of the cable of a bowden cable assembly completely therethrough and further operable for engaging a sleeve of the bowden cable assembly for preventing movement of the sleeve completely therethrough. The barrel is fixedly coupled to the housing to fix the movement of the bowden cable sleeve with respect to the housing passage such that movement of the screw in the housing is operable for drawing the cable through the fixed sleeve of the bowden cable structure for manipulating a lumbar support structure.
