Abstract
There is disclosed a tilt control mechanism for a keyboard support platform. The keyboard support platform is of the type that includes linkage for connecting the platform to a work surface. The linkage further includes linkage arms that pivotally connect the keyboard support platform to the work surface. The tilt control mechanism comprises a tilt adjustment actuator arm and a pawl and ratchet connection between the actuator arm and the support platform. The pawl and ratchet provide a series of separate detent positions which define distinct length actuator arm connections between a fulcrum point and the support platform to thereby control the tilt of the platform.
