Patent ID: 7040704

Claim:
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 substantially coplanar with the first backrest, a second buckle support supporting a second belt 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 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.
