Arrangement in a recline chair
First Claim
1. Arrangement in a recline chair, including a chair back (2) adjustable in relationship to a chair seat (5), and a neck support (3), said chair back (2) being mounted to pivot around a horizontal, stationary axis (9) in relation to a chair frame (4) and at a lower end of said chair back (2) being hinged to the chair seat (5) through a connection link (9A) so that various inclined positions of the chair back (2) about the axis (9) will shift the chair seat (5) back and forth in relation to the chair frame (4) via a chair seat sliding mechanism (8), said chair back (2) also comprising appropriately resilient elements (15) mounted behind cushioning of the chair back (2) and constituting a lumbar region support (6), characterized in that the arrangement comprises influencing means (12) arranged stationary in the area of said axis (9) and inside the cushioning of said chair back (2), said influencing means comprising an end portion (16) extending downwardly and inwardly from the axis (9) of the chair back (2) so as to be in contact with said resilient elements (15) constituting the lumbar region support (6) of the chair back (2) in dependence of the inclination of the chair back (2), said resilient elements (15) thus being pressed forwardly by said downwardly extending end portion (16) to constitute a pronounced support for the user'"'"'s lower back when the chair back (2) is in erected position and said chair seat (5) retracted closer to said axis (9), whereas said resilient elements (15) will be removed from said end portion of said influencing means (12) and thereby constitute a less pronounced lumbar support when the chair back (2) is in a more rearwardly inclined position and said chair seat (5) is displaced further away from said axis (9).

Abstract
An arrangement in a chair (1), having an adjustable chair back (2) and a neck support (3), characterized in that the arrangement comprises a device (12, 15) which influences the shape of the chair back (2) in dependence of the inclination of the chair back (2). The chair provides a pronounced support for the user'"'"'s lower back when the chair back (2) is in an erected sitting position, whereas the device (12, 15) renders a gradually decreasing support of the user'"'"'s lower back when said chair back (2) is lowered rearwardly towards a lying position. The lumbar region support (6) co-operates with a system for regulating the neck support (3) and the return thereof to a normal position each time the chair back (2) arrives at an extreme upper or lower position.
