Vehicle seat and method for using the seat

A vehicle seat (1) comprising:

• a squab with a front edge and a rear edge,
• a slideway comprising a first element and a second element, the first element being intended to be fixed to a vehicle floor and the second element being configured to slide relative to the first element in a longitudinal direction between a forward end position and a rearward end position, in a forward direction or in a rearward direction, opposite to the forward direction,
• a front connecting rod having a lower front end and an upper front end,
• a rear connecting rod with a lower rear end and an upper rear end,
• a connecting rod with an intermediate front end and an intermediate rear end,
• a latch having an active state and an inactive state, in a usage configuration of the seat, the latch is in the active state and holds the squab relative to the second element of the slideway at least along the longitudinal direction, in the inactive state the latch does not hold the squab relative to the second element of the slideway,
• an elastic element,
• wherein:
• in the vicinity of the lower front end, the front connecting rod is rotatably mounted on the second element of the slideway about a lower front hinge axis, in the vicinity of the upper front end, the squab is rotatably mounted on a front connecting rod about an upper front hinge axis,
• in the vicinity of the lower rear end, the rear connecting rod is rotatably mounted on the first element about a lower rear hinge axis, and the lower rear hinge axis is movable in the longitudinal direction,
• in the vicinity of the upper rear end, the squab is rotatably mounted on the rear connecting rod about an upper rear hinge axis,
• in the vicinity of the intermediate front end, the linking rod is rotatably mounted on the front connecting rod about an intermediate front hinge axis,
• in the vicinity of the intermediate rear end, the linking rod is rotatably mounted on the rear connecting rod about an intermediate rear hinge axis,
• the lower front hinge axis, the upper front hinge axis, the lower rear hinge axis, the upper rear hinge axis, the intermediate front hinge axis and the intermediate rear hinge axis extend in a transverse direction, perpendicular to the longitudinal direction,
• the elastic element urges the lower rear hinge axis to move forward in the longitudinal direction,
• the seat is configured to switch from the usage configuration to a retracted configuration after switching from the active state to the inactive state of the latch, by a retracting movement of the rear edge of the squab, moving the lower front hinge axis closer to the lower rear hinge axis over a retracting distance, the retracting movement comprising a forward component in the longitudinal direction.
