Abstract

Abstract A seat has an armrest pivotable between an operating position approximately parallel to the seat cushion and a position parallel to the seat back, and translatable in the operating position between two heights with respect to the seat cushion. A first member (6) fixed to the seat back (1) includes an arcuate cutout (21) and a pin-receiving portion (23). A second member (5) is pivotably connected to the first member (6) opposite a first end of the cut-out (21), and is pivotably connected to the armrest (2), the distance between the pivotal points approximating the radius of curvature of the cut-out (21). The armrest (2) has a projecting pin (20) engagable in the cut-out (21 which serves to guide the pin (20), and thus the armrest (2), during rotation of the armrest (2). A recess at the first end of the cut-out (21) allows the pin (20) to disengage therefrom and the pin (20) can then be raised to the level of the pin-receiving member (23) and supported thereby.
