First Claim
1. A seat having a reclinable back-rest, said seat comprising:
- a fixed supporting portion adapted for supporting the seat off a floor;
a seat portion comprising a reclinable back-rest and a seat connecting device adapted for connecting said seat portion to said supporting portion, said connecting device including a back-rest reclining mechanism adapted for allowing and controlling movement of said back-rest between a first upright position and a second fully reclined position;
wherein said back-rest comprises a first lower back-rest member having an upper end and a second upper back-rest member that is superposed to said first back-rest member and pivotably coupled to the upper end thereof so as to transmit translational movement therebetween, said back-rest reclining mechanism comprises first and second elongate guide tracks attached to the supporting portion or a part connected thereto, said first track having two opposing track-ends, a plurality of first spaced track-engaging follower members attached to said first back-rest member adapted to engage and slide in one of said tracks and a second track-engaging follower member coupled to said second back-rest member or a part connected thereto, said first track being curvilinear such that as the first track-engaging follower members slide along said first track from one end to the other, said first back-rest member is caused to rock progressively relative to said supporting portion between said first upright position and said second fully reclined position, and said second track having a profile such that as said second track-engaging follower member is caused to slide along said second track, said second back-rest member is caused to rock progressively with respect to said first back-rest member.

7. A seat having a back-rest reclinable between an upright position and a reclined position, said seat comprising:
-
a lower back-rest portion; an upper back-rest portion pivotably coupled with respect to the lower back-rest portion; a first follower coupled to said lower back-rest portion; a second follower coupled to said lower back-rest portion and to said upper back-rest portion; a support comprising a first guide configured to receive said first follower, said first guide being oriented such that as the first follower moves along said first guide from one end toward the other, said lower back-rest portion moves relative to said support between an upright position and a reclined position, said support also comprising a second guide configured to receive said second follower, said second guide being oriented such that as the second follower moves along said second guide, said upper back-rest portion pivots with respect to said lower back-rest portion; wherein said upper back-rest portion is configured to pivot forwardly with respect to said lower back-rest portion from the upright position to the reclined position, and said upper back-rest portion is configured to pivot rearwardly with respect to said lower back-rest portion from the reclined position to the upright position. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
