Abstract
A seat pan of an automobile vehicle seat includes an anti-sub-marining cross member to limit the movement of a pelvis of a user towards the front of the seat, the cross member extending crosswise to a seat pan framework and being able to move towards the front while exerting pelvis retention forces during the movement of the pelvis and cross member towards the front of the seat. The seat pan includes energy dissipation means to control, from a predetermined threshold, forces transmitted by the cross member to the occupant of the seat. The ends of the cross member are connected to links that pivot on the seat pan framework about an axis passing through lower ends of said links so that the movement of the cross member towards the front is in the form of an arc of a circle, defined by the pivoting of the links towards the front, opposing the retention force exerted by the energy dissipation means which are connected to upper ends of the links and near the cross member.
