Abstract: A child's seat for a motor vehicle comprises a back portion and a harness including two shoulder straps each of which projects through a respective opening in the back portion. Each opening is formed by the interaction of an elongate slot formed in the back portion and extending over the range of desired positions for the opening, with a horizontal slot in a carriage mounted on the rear side of the back portion for vertical sliding movement relative thereto. Manually operable control means is arranged to vary the position of the carriage relative to the back portion.

Abstract: A toddler seat has a base adapted to sit on the seat part in rearward engagement with the back part, having an upwardly directed seat surface on which a toddler can sit, and provided below the surface with a pair of opposite sides laterally flanking the surface and extending vertically and in the travel direction. Respective guides on the sides extend obliquely upward and forward thereon. Respective arms have lower ends at the guides upper ends above and flanking the seat surface, the belt normally passing around the upper ends of the arms. Respective complementary and interengaging formations at the lower ends and guides allow the arms to slide along the guides without pivoting so that the relative angular positions of the upper and lower arm ends do not change as the arms slide along the guides.

Abstract: The child-passenger safety restraint for a seat of a vehicle comprises a safety seat positioned on the vehicle seat and a restraining body securable by a safety belt of the vehicle seat, the restraining body being held on the safety seat with its relative height and horizontal position adjustable according to the size of the child seated. The restraining body and the safety seat are attached to each other by a coupling mechanism that includes at least one member adjustable in itself and/or relative to the safety seat and/or relative to the restraining body and securable in a particular position, with whose help the optimum position of the restraining body for safe restraint is adjustable and securable relative to the safety seat and the child.
