Abstract
A seat pan is provided for an automobile vehicle seat and includes an anti-sub-marining cross-member that limits the movement of a user's pelvis toward the front of the seat. The cross-member extends crosswise to a seat pan framework and moves under the action of a cable, from a rest position to an extended position. In the extended position, the cross-member limits the movement of the user's pelvis toward the front of the seat. The ends of the cross-member are guided along a first trajectory and the seat pan includes energy dissipation means for controlling, from a predetermined threshold and from the extended position of the cross-member, forces transmitted by the seat to a user.

A seat pan for an automobile vehicle seat, the seat pan comprising:
- an anti-sub-marining cross-member to limit movement of a user's pelvis towards the front of the seat, the cross-member extending crosswise to a seat pan framework and which can move, under action of a drive means, from a rest position to an extended position where the cross-member limits the movement of the pelvis towards the front of the seat, ends of the cross-member being guided by guide means along a first trajectory, and the seat pan including energy dissipation means to control, from a predetermined threshold and from the extended position of the cross-member, the forces transmitted by the seat to the user, the first trajectory being oriented upwards and towards a rear of the seat.
