Abstract: 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.

Abstract: A vehicle radio mount having a first member adapted to be mounted to the underside of a vehicle dashboard and having two opposed elongate transversely spaced parallel slide elements. A plurality of exposed conductive contacts are mounted in downwardly facing position in the first member and are connectible to respective vehicle power supply, amplifier, speaker, antenna and other circuits. A locking ridge is formed in downwardly facing position in the first member. A second member, adapted to be connected to a vehicle radio, has a pair of parallel elongate transversely spaced slide receiving grooves which correspond to and are registrable with the slide elements in the first member. A stop is formed at the end of each groove. A tab carrying a locking boss is resiliently cantilevered to the second member and extends adjacent to and is manually accessible to a manual gripping portion on the second member.
