    Abstract: A chair includes a support assembly comprised of a first leg set having two space first bars and a second leg set having two space second bars located between and pivoted to the first bars. A backrest has is rotatable with respect to the support assembly to selectively change a tilting angle thereof. A tubular slide is movably fit over a free end of each first bar and is pivoted to the backrest. The slide has a fastening device to selectively secure the slide with respect to the first bar thereby releasably securing the backrest at a desired tilting angle. A wire and a spring are selectively connected between the slide and the first bar to prevent the slide from undesired separation from the first bar and to induce a returning force to move the backrest from a tilted position back to a regular position.

  • Patent number: 4244619
    Abstract: The folding chair has uniquely hinged components so that it may be folded into a small, compact unit. Side supports are mounted so as to lie substantially parallel to the back support when folded, and to extend substantially perpendicularly from the back support when unfolded. The back of the chair is pivotally mounted on the back portion so that it rests against the outer surface of the back support when the chain is folded and it rests at a slight angle to the vertical plane between the side supports when the chair is unfolded. Pivotally mounted on the back of the chair is a seat which rests substantially parallel to the back when the chair is folded and rests in a substantially horizontal plane between the side supports when the chair is unfolded.
