Abstract: The present invention relates to a seat for airplanes, buses and like vehicles. The seat comprises a frame, an upholstery support, and a three-piece device for locking both sides of the upholstery support in a selectable pivot position. The locking device includes a stepless adjustable-length bar in the nature of a hydraulic piston, a body for connecting the front end of the hydraulic piston to a front cross member of the seat frame, and a pivot lever for attaching the rear end of the hydraulic piston to a rear cross member of the upholstery support.

Abstract: A vehicle seat, particularly for airplanes or omnibuses and the like, wherein the seat is equipped with a retractable leg support which can be extended to provide a support for the legs of the user of the vehicle. In contrast to known seats of this type, the leg rest can be securely stopped and held in any intermediate position of the leg support between the two end positions. This is accomplished by means of a cog and chain or belt strand connected with drive means and a self-arresting gearing arrangement.
