A carrier for the partial seat cushion of a car seat, in particular a motor vehicle seat is disclosed. The carrier includes two side members which extend in the longitudinal direction of the seat and to which is hinged a longitudinal member of a leg support bearing the front portion of the partial seat cushion so as to pivot around an axis, extending in the transverse direction of the seat, and to be fixed into selectable swivel positions. A spring-loaded swiveling device is assigned to the leg support wherein said swiveling device exerts on the leg support a swivel force, which is smallest in the lowest swivel position and increases until the highest swivel position has been reached.
