Apparatus and method for braking ergonomic support actuator

摘要

A braking actuator for continuously positionable ergonomic support has a continuously positionable ergonomic support connected by a Bowden cable to the actuator. The actuator has a housing with pin slots, friction surfaces and an oval mount for a disk axle. A disk has frictional surfaces, holes with pin load edges, a Bowden cable wire seat that holds the Bowden cable end and an axle that mounts in the oval mount in the housing. The friction surfaces of the disk and housing engage to brake the actuator and the ergonomic support. A lever having pins is disposed on said housing such that said pins extend through the pin slots to operatively engage the holes in the disk such that the friction surfaces can be disengaged and said disk rotated. Turning the lever disengages the friction surfaces to actuate movement of said ergonomic support. Releasing said lever engages said frictional surfaces such that movement of said ergonomic support is braked at a selected position.
