SEDILE PER VEICOLI, PARTICOLARMENTE AUTOVETTURE

Each side of the seat squab (C) is supported by the upper ends of two arms (1, 2) whose lower ends are hinged to a rigid support member (3). The upper ends (1a, 2a) of the arms are interconnected by the rod (8) of a Porter-type locking device (9) whose body (10) is mounted on the support member (3) so that it is substantially fixed against movement in a forward-rearward direction but can move a certain distance vertically. When the Porter device (9) is disengaged, the position of the squab (C) can be varied selectively by the pivoting of the arms (1, 2). The position of adjustment thus reached may then be retained firmly by the return of the Porter device (9) to its engaged condition.
