Abstract
In a chair with elevated seat surface and footrest, a seat (30, 114), a footrest (38, 162)and a backrest (24) are connected with each other in such a manner that they are swingable jointly from a position suitable for sitting with seat substantially horizontal into a position with strongly forward inclined seat in which the chair can be used as standing rest. The joint swinging is effected by means of a yoke (22; 88, 94; 130, 132, 136, 138) which extends from the footrest to the backrest and consists of a single piece or else can be divided into at least two yoke sections. The seat, the footrest and/or the backrest can be adjustable by separate adjustment devices (46, 50, 60) with respect to the yoke, and in the event of the use of a plurality of divided yoke sections, adjustment devices (98, 140) can be provided in the connection regions of the sections.
