Abstract

A restraining system for a child's car seat having a pair of arms raised and lowered with respect to the seat and a shield movable relative to the arms. The restraining system includes means for retaining the selected positioning of the shield and means for releasing the retaining means to permit relative movement of the shield and arms. A plurality of recesses are formed on a lower surface of the shield. The retaining means comprises a plunger having a protrusion at one end engaging one of the recesses. The releasing means includes a lever movable in a direction substantially parallel to the lower surface of the shield. The lever includes a camming surface opposing a first biasing means biasing the plunger into its retained position. Actuation of the lever releases engagement of the plunger from the recesses. A second biasing means biases the releasing means out of engagement with the retaining means.
