Abstract

The working chair has a seat bearer (11), a seat (15) articulated on the seat bearer (11) and a squab bearer (25) with a squab (29). The squab bearer (25) has a spindle (23) on the seat bearer (11). One arm (27) is articulated on the squab (29) and the other (31) on the seat (15). The simple mechanical arrangement (20, 22, 23, 25, 35) thus formed causes the seat to be moved in one direction of rotation (47) when the squab bearer (25) is moved in the other (43). As in lying down and relaxing, the knee and hip joints thus undergo an extension. This produces a sound lordosis. The spindle (23) and the articulation axis (35) lie in a plane (36) inclined at about 70 DEG to the horizontal. Regardless whether a person is heavy or light, relatively little force on the squab (29) is needed to raise the seat (15). As the seat (15) and the squab (29) remain close together during any movement, the tendency for the shirt to be pulled out is prevented. The movement of the seat backwards and downwards when the squab is tipped backwards prevents blood congestion at the back of the knees.
