摘要

Improvements introduced in retractable seats with synchronized automatism in the maneuver of evolution from the service position to the folding position and vice versa, characterized in that the seat is linked to an external support that involves rotating enclosing elements joined to the support arm carrying the mechanism, with a helical groove in one of them through which a driving pin passes in an up and down maneuver, which is linked to the support in a vertical direction by passing through a straight slot of the latter, producing a push during its ascent or descent maneuvers lateral against the helical groove that gives rise to a turning movement of the wrapping elements together with the support arm and the seat to one side or the other, to cause its evolution from the service position to the retracted position and vice versa in movement of circular displacement, but the attachment of the seat is made not to the arm of the but to a telescopic tubular element, which has a joined groove of helical groove with the support arm, and with the existence of transmission means that as a consequence of the rotation of the support arm with respect to the support produce an axial displacement in one or the other direction to the tubular element, causing with this displacement the rotation of said tubular element due to the helical groove bonding thereof with respect to the supporting arm, so that the ascent or descent maneuver of the python housed in the helical groove of the the envelope of the external support causes the circular movement of the seat and gives rise synchronously to the turning and radial displacement of the latter, in the automatic achievement of the evolution maneuvers from the folding position to the service position and vice versa.
