Seat with an adjustable and tiltable backrest.

摘要

This seat comprises a backrest armature (1) and a seat cushion armature (4) which are connected together by an inclination shaft (2) housed in a recess in the seat cushion armature. The backrest armature also carries a curved stalk (28) terminated by fingers (22 and 24) which are fitted into notches (20) in the slot (18) in the seat cushion armature. One of the fingers (22) forms an axis of tilting while the other (24) constitutes a limiting end stop for the tilting. A locking lever (30) is hooked onto a pin (34) on the seat and pivots with respect to the inclination shaft (2) in order to drive the stalk (28) and unlock the fingers (22 and 24).
