1. An aircraft seat comprising:
a guiding rail,
a rack,
an actuator equipped with a pinion carried by a shaft, said pinion meshing with the rack,
at least one connecting portion providing a mechanical connection between the guiding rail and the rack,
characterized in that the connecting portion comprises a zone of low mechanical resistance and in that a first support element and a second support element are arranged on either side of the rack so that, in case of a deformation of the seat causing a displacement of the pinion, said pinion or the corresponding shaft bears against one of the support elements so as to deform the connecting portion along the zone of low mechanical resistance, and
characterized in that the second support element is a plate provided with a guiding groove suitable for guiding one end of the shaft carrying the pinion.
