Abstract

A child-restraint seat includes a seat shell, a child-restraint harness coupled to the seat shell, and a harness-control panel including a belt-receiving opening receiving a shoulder belt portion of the child-restraint harness. The harness-control panel is mounted on the seat shell for up and down movement relative to the seat shell to raise and lower the shoulder belt portion of the child-restraint harness with respect to the seat shell. The child-restraint seat further includes a panel-height adjustment mechanism coupled to the harness-control panel and movable between a locked position to prevent the harness-control panel from moving up and down relative to the seat shell and an unlocked position to allow the harness-control panel to move up and down relative to the seat shell. The panel-height adjustment mechanism is accessible to a user from both a front side and a rear side of the child-restraint seat.
