The problem is to provide an adjustable school bus seats that may be adjustably positioned
to occupy either of two positions, one in which the seat cushion will project forward enough to accommodate a tall adult child, and a second positionsuitable to accommodate a small child, with the child's back, in either case, resting against the back rest of the seat and with his legs bent at the knees, to permit his legs to bend at the knees and dangle over the front edge of the seat.
