Abstract
A rotary coupling to attach an infant seat to the passenger seat of a vehicle. This invention is a child-restraining device for mounting in the passenger seat of a vehicle that has at least one rigid member fixedly mounted in the bite between the passenger seat's seat portion and back portion. In particular, the child-restraining device of this invention has a child seat and at least one rotary coupling to attach the child seat to the rigid member. The rotary coupling is characterized by: a rigid hollow cylinder with two notches in one end, a piston that slides back and forth inside the cylinder, a spring to push the piston toward the notches; a means to prevent the piston from sliding out of the cylinder, and a means to attach the rotary coupling to the child seat. The coupling is operated by pushing the piston back within the cylinder and placing the rigid member in the cylinder's notches. Once in the notches, the piston is released and the spring exerts a force that holds the rigid member between the piston and the notches. The coupling can then be released by again pulling back the piston and removing the rigid member from the notches.
