Abstract
A seat back of a vehicular seat is movably supportable in the fore and aft direction relative to a seat cushion and lockable in its forward and rearward positions. The back side of the seat back serves as a part of a seat for a child in the forward position in which the child is restrained relative to the seat back by a seat belt assembly, while the front side of the seat back serves as a part of a usual passenger seat in the rearward position, thereby providing a sufficient comfortableness to the seated child without deteriorating the function of the usual passenger seat.
