Bus Seats With Two Positions

Why we should manufacture two position bus seats for childrens school bus seats

? The reason is that can protent children from injury.

Children's school bus seats are adjustable to either of two positions: (1) a forwardly projecting position to provide a longer depth seat for larger children with longer leg thighs; and (2) a backward position to provide a shorter depth seat for smaller children with short thighs; so all can sit back comfortably against the back rest cushion with their knees bent and legs dangling.

In adults the thigh dimension is relatively long, and bus seats are generally deep enough to accommodate the long thigh of the adult, with the leg still able to bend at the knee and dangle. In children, however, their thighs are still relativelyshort, and the usual bus seat is of such long depth, from front to rear, that it is not possible for a small child to sit comfortably against the back of the seat and have his knees able to bend enough so that his legs can dangle comfortably over thefront edge of the seat. If the children sit back in order to have the comfort of the back rest, their legs are too short to bend at the knees, and consequently the calves of their legs rest on the front edge of the seat which they are occupying, andtheir legs soon tire.

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.
