Abstract

A child restraining seat having a harness with an adjuster for controlling harness sizing. In the preferred embodiment, the harness includes a pair of belts fixedly secured to a pad having a downwardly extending tongue lockingly received by a belt buckle secured to the seat between the legs of the child. The opposite ends of the belts extend slidably through the seat back being attached to a moveable bar. A third belt attached to the moveable bar extends forwardly through a slot in the forward portion of the seat and is adjustably received by an adjuster mounted to the front of the seat. The adjuster includes a spring biased cam member for lockingly holding the third belt in place. Alternate embodiments include such a harness assembly having the buckle fixedly secured thereto with a tongue secured to the seat. A further embodiment includes a harness assembly with a pair of belts slidably received through a pair of tongues with the belt then extending slidably through the seat arms being fixedly attached to the seat frame. The tongues are lockingly received by a buckle secured to the seat. A further embodiment includes a manually operable remote pivot rod for manually pivoting the cam member.
