- the improvement wherein said hinge device includes;
i) at least at one free end (9) of the seat squab frame (2) a removable journal member (10) rigidly coupled with and fastened to the seat squab frame (2), projecting out of the seat squab frame (2) and aligned with the tilt axis;
ii) at the rear free end (8) of the seat cushion frame (3) facing the journal member (10) a journal support (11) adapted to support the journal member (10) rigidly coupled with and fastened to the rear part (7) of the seat cushion frame (3), projecting into the seat cushion frame (3) and aligned with the tilt axis;
iii) coupling means (12,
13) on the journal member (10) and the journal support (11) respectively adapted to couple the journal member (10) and the seat back (2) with the journal support (11) and the seat bottom (3), and providing a coupling position enabling rotation of the journal member (10) about the tilt axis (4), the journal member (10) extending axially over a part of the tilt axis segment between the free end (9) of the seat squab frame (2) and the rear free end (8) of the seat cushion frame (3).

Abstract
A hinge device for seats of public transport vehicles--especially airliners--adapted to allow the seat squab frame (2) to tilt relative to the seat cushion frame (3) about a tilt axis (4). The seat squab frame (2) is generally U-shaped with the web forming the top of the seat squab frame (2) and the sides forming the lateral edges (6) of the seat squab frame (2). The seat cushion frame (3) has a rear part (7) including two rear free ends (8). The tilt axis is horizontal and passes through the rear free ends (8) of the seat cushion frame (3) and the free ends (9) of the lateral edges (6) of the seat squab frame (2). The hinge device includes at least one free end (9) of the seat squab frame (2) a journal member (10) rigidly coupled with and fastened to the seat squab frame (2), projecting out of the seat squab frame (2) and aligned with the tilt axis; at the rear free end (8) facing the journal member (10) a journal support (11) rigidly coupled with and fastened to the rear part (7) of the seat cushion frame (3), projecting into the seat cushion frame (3) and aligned with the tilt axis; the journal member (10) and the journal support (11) having respective coupling structure (12, 13) providing a removable and secure coupling and enabling rotation of the journal member (10) about the tilt axis, the journal member (10) extending axially over a substantial part of the tilt axis segment between the free end (9) of the seat squab frame (2) and the rear free end (8) of the seat cushion frame (3).
