ABSTRACT:
A reclinable seat for use in vehicles provides two systems enabling an occupant to adopt reclining postures. The seat comprises a bottom part and a back support part which are rotatable together about an axis in a support frame to be fixed in the vehicle. The axis is transverse to the seat and is adjacent to the bottom part, enabling the seat to be rotated bodily about the axis into reclining positions. The back support part is pivoted to the bottom part so that it can be tilted separately into reclining positions. Separate piston/cylinder control assemblies are provided for respectively locating the seat in positions angularly spaced about the axis and for locating the back support part in angularly spaced positions relative to the bottom part. A limiting mechanism is provided for limiting the permitted angle between the back support part and the bottom part, the limiting mechanism being influenced by rotation of the bottom part about the axis so as to reduce the permitted angle porgressively as the bottom part is rotated rearwardly from its normal substantially horizontal position.
