ABSTRACT:
A device for varying the distance between the seats in commercial aircraft, comprising longitudinal rails provided in their upper horizontal flanges with dovetail grooves and holes pierced in the two inner lips of the rail defining this groove, comprises a driving seat and mobile seats disposed in front of and/or behind the driving seat. A transmission mechanism is provided between the driving seat and the mobile seat. The driving seat bears a drive mechanism moved by a motor, this drive mechanism being coupled with elongated connecting members movable in translation, located on each rail and being able to be displaced forwardly or rearwardly by a predetermined distance as a function of the desired change in distance. The transmission mechanism comprises a set of metal slats connecting the feet of the mobile seats together, at rail level, the slats closest to the driving seat being coupled to the elongated connecting members. Means are associated with the feet of the mobile seats for automatically controlling the unlocking of the seat as soon as the slats are displaced.
