CA 2404803

A simple, inexpensive and reliable chair adjustment mechanism is disclosed. The mechanism includes a base which is fastened to a chair support, a slide attached to an assembly to be adjusted, such as a back or a seat or arms, and a spring device cradled by the base for engaging one of a series of spaced ramps integral with the slide. The slide also includes ramps for pushing the spring device into an out-of-the-way position secured to two hooks on the base so that at the end of the slide's extension it may be returned to a retracted position in one easy movement. When reaching the retracted position, other ramps push the spring device out of the engagement with the hooks so that the spring device extends through a space between the base and the slide to again selectively engage the series of spaced ramps.
