Abstract
A headrest device, intended for a chair, a seat or the like having a substantially vertical backrest, has an attachment part ( ), by means of which it is to be attached to the backrest, and a headrest ( ), which is mounted on the attachment part ( ). The headrest ( ) is mounted on the attachment part ( ) by means of two link arms ( ), which at one end are connected, pivotally about a substantially vertical pivot axis, to the attachment part ( ) and which at the other end are connected, hingedly about a substantially vertical axis, to a respective nut element ( ). The nut elements ( ) are threadingly engaged with a substantially horizontal screw ( ), which is turnably attached to the headrest ( ) and which is arranged, in turning, to synchronously displace the nut elements ( ) in opposite directions along the screw ( ) and thereby to pivot the link arms ( ) about their pivot axes to change the horizontal distance of the headrest ( ) from the attachment part ( ).
