Abstract: A piece of furniture has a generally stationary main part, an actuator in the main part, and a movable part that is pivotal on the main part generally about an axis. An actuating assembly for the movable part has an elongated one-piece operating bar formed of a single piece of tubing having a central portion extending along the axis and a pair of U-shaped end portions each having an inner arm forming a continuation of a respective outer end of the central portion and an outer arm extending across the axis, projecting radially therefrom, and provided with mounting formations. The portions and arms all are generally coplanar. Pivot pins fixed on the main part engage through the outer arms at the axis for pivoting of the operating bar on the main frame about the axis. Respective fittings secured to the mounting formations of the outer arms are connected to the movable part and a crank arm fixed on the central portion and extending radially therefrom is operatively connected to the actuator in the main part.

Abstract: A cervical support to immobilize the cervical vertebral column is in the form of a padded collar enclosing the patient's neck and so designed that individualized immobilization is possible within a limited region of the head, as required in a number of indications, for instance in wear phenomena in the cervical vertebral column zone or in post-operation treatment.For that purpose the invention provides that the cervical support comprise a clearance in its front region with a flexible frame comprising spacers between its upper and lower bounds that can be shifted along the clearance.

Abstract: A cervical support to immobilize the cervical vertebral column and in the form of a padded collar enclosing the patient's neck is designed in such a way that in spite of the immobilization in the region required for that purpose, some head motion to actuate the muscles and to avoid a long-term unpleasant feeling of compression shall be possible.The invention provides that the cervical support shall be relatively rigid in a region supporting the head and relatively elastically deforming in another region.
