ABSTRACT:
A device for adjusting and locking the inclination of the backrest of a seat, for example an aircraft seat, comprises a gas compression spring which acts between the back rest and the frame of the seat and which is of the type which has a locking and release member, which, when pressed frees the spring to expand or to be compressed and when released locks the spring in any position in which it is set to lock the back rest. The locking and release member is operated by a button fitted in an arm rest of the seat. To enable the button to operate the locking and release member entirely mechanically, the button is connected to one end of a Bowden cable through a first lever and the other end of the Bowden cable is connected to the locking and release member through a second lever. The two levers together provide a mechanical advantage of 8:1 between the force applied to the button and that acting on the locking and release member.
