The present invention concerns a displacement system (1) for a seat, in particular an airplane seat, said seat comprising a sitting portion, a backrest and a legrest, said displacement system (1) comprising a support structure (2) for the support of said seat, a sitting portion structure (3) for the support of said sitting portion, said a sitting portion structure (3) being connected to said support structure (2) and comprising a sitting portion surface lying at least on a first plane (±), and displacement means (4) acting at least on said sitting portion structure (3) in such a way that said displacement system (1) passes between a first configuration or sitting configuration and at least a second configuration or cradle configuration and vice versa, said displacement system (1) being characterised in that said sitting portion surface is subdivided into at least two sitting portions (5, 6), a first portion or back portion (5), lying on said first plane (±), and a second portion or front portion (6), lying on a second plane (²), said portions (5, 6) being constrained in rotation with each other in the passage between said first configuration to said at least a second configuration, and vice versa, said displacement means (4) being configured in such a way to act on said second portion (6) so that in said first configuration said second plane (²) is inclined with respect to said first plane (±) by a first angle (x 1 ) substantially of 180°, and in said at least a second configuration is inclined by a second angle (x 2 ) positive and smaller than 180°. |
