Patent ID: 7992940

Claim:
An actuating device for use in rotating a fixing rod for a headrest of a motor vehicle to allow displacement of the fixing rod in a longitudinal direction, the fixing rod rotatable between a locked position in which the fixing rod is prevented from displacement in the longitudinal direction and an unlocked position in which the fixing rod is displaceable in the longitudinal direction, said actuating device comprising: a bearing sleeve; a coupling slide mounted in said bearing sleeve, said coupling slide displaceable in an actuating direction; and a mechanism in engagement with said coupling slide and adapted to rotate the fixing rod, said mechanism comprising: a coupling arm, said coupling arm pivotably fitted to said bearing sleeve, said coupling arm pivotable with said coupling slide over an angle range; and a coupling head rotationally fixedly connected to the fixing rod, said coupling head coupled to said coupling arm whereby pivoting movement initiated by the actuation of said coupling slide is transmitted as rotary movement to said coupling head to in turn rotate the fixing rod between the locked position and the unlocked position.
