The invention relates to an underframe for a passenger aircraft seat, the underframe including a triangular base defining a front anchor point and a rear anchor point, and a raised intermediate vertex; and a leg associated via its top end with the structure of the seat and via its bottom end with the triangular base. In accordance with the invention, the leg is associated rigidly with the base by rigid association means which, during normal use of the seat, hold the leg positively relative to the base, in particular so as to prevent any forward or backward pivoting of the leg.
