Abstract
Two diametrically opposed orifices (4, 6) are provided in the framework tube of the backrest of the seat structure and receive the headrest support bar (1) which extends therethrough. A locking lug (10) projecting inside the tube extends into a notch in this bar and immobilizes it. The lug (10) is carried internally by a collar (12) which partly covers the tube (2) and extends round the upper orifice receiving the bar (1). A guide socket (24) is fitted into an opening (18) of the collar coaxially with the upper orifice (4).
