There is disclosed an adjustable tilt mechanism for a keyboard support platform. The keyboard support platform is of the type that includes a linkage for connecting the platform to a work surface. The linkage further includes connecting arms which pivotally connect the keyboard support platform to the work surface. The adjustable tilt mechanism of the present invention includes a tilt adjustment member that is movable transversely relative to the pivot axis of the platform. Engaging the tilt adjustment member is an angled shaft which is fixed to the platform between the sides of the platform. The tilt adjustment member is also pivotal about a second fixed shaft that is parallel to the pivot axis of the platform. A releasable latching member is mounted on the connecting arms for engaging and releasing the tilt adjustment member. In operation, upon the release of the latching member, slidable movement of the tilt adjustment member alters the pitch of the keyboard support platform, thereby permitting selective adjustment of the work angle of the keyboard.
