ABSTRACT:
This invention relates to a multi-position, foldable armchair whose backrest inclination and seat height are adjustable, comprising, on each side, a crossed support of which the rear leg is articulated about a pivot pin under the front part of a seat and of which the front leg is connected to the rear part of the latter by a finger-rack arrangement. It also comprises a backrest articulated about a pivot pin on the front leg. Finally, it comprises an armrest articulated about a pin on the backrest and connected by a pin-rack arrangement to a compass element of which the front arm is articulated about a pin on the seat and of which the rear arm is articulated about the pin on the front leg. According to the invention, the rack of the seat is disengageable from the finger of the front leg and the rack of the armrest is releasable from the finger of the compass element, so that the armchair can be folded down flat.
