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.

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).
