Abstract

A seat system includes two backrests installed so as to pivot around a backrest axis in relation to a floor between a raised position and a folded down position, and a first belt locking buckle installed so as to pivot in order to retract, first connecting system between a first backrest and the first buckle so that the pivoting of the first backrest causes the first buckle to pivot between a high position and a retracted position, a second belt locking buckle aligned with the first buckle in a plane perpendicular to the backrest axis, the second buckle being connected to the second backrest by a second connecting system in such a manner that the first buckle pivots in a first direction when the first backrest is pivoted from the raised position to the retracted position, and the second buckle pivots in a second direction opposite to the first direction when the second backrest is pivoted from the raised position to the folded down position.

Claims

1. A seat system comprising:

a first backrest installed so as to pivot around a backrest axis in relation to a floor between a raised position and a folded down position;

a first buckle support supporting a first belt buckle and installed so as to pivot to retract the first belt buckle;

first connecting means between the first backrest and the first buckle support so that the pivoting of the first backrest causes the first belt buckle to pivot between a high position and a retracted position;

a second backrest installed so as to pivot around the backrest axis and with a raised position in which the second backrest is more or less coplanar with the first backrest, a second buckle support supporting a second belt locking buckle aligned with the first belt buckle in a plane perpendicular to the backrest axis, the second buckle support being connected to the second backrest by second connecting means in such a manner that the first belt buckle pivots in a first direction when the first backrest pivots from the raised position to the folded down position, and the second belt locking buckle pivots in a second direction, opposite to the first direction, when the second backrest pivots from the raised position to the folded down position.

2. The system according to claim 1, in which the first connecting means comprises a backrest lever, attached to the first backrest, a buckle lever attached to the first belt buckle and a buckle link connecting the backrest lever and the first belt buckle together.

3. The system according to claim 2, in which the first belt buckle is located further forward than the second belt locking buckle, said second connecting means includes a second backrest lever, the backrest levers being positioned downwards, the first buckle lever, the first buckle link and the first backrest lever of the first connecting means forming a U, and a second buckle lever, a second buckle link and the second backrest lever of the second connecting means forming a Z.

4. The system according to claim 1, in which a seat pan is installed so as to pivot, on the one hand, on the first backrest and, on the other hand, on at least one seat pan link, the at least one seat pan link being intended to be installed so as to pivot on the floor so that the seat pan moves towards the floor when the first backrest is placed in folded down position.
