ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to infant car seats, and more specifically, to an infant car seat that provides for the selective linear and rotational movement of the infant seat to allow a user to remove or place a child therein without awkward twisting and turning. The present invention has a stationary platform comprising a lower horizontal plate and a vertical plate extending from one edge thereof. Said stationary platform is secured by the seatbelts against the rear seat of the automobile adjacent the door. The child seat is pivotably attached to a vertical portion of the stationary platform by means of a hinge assembly that allows the user to stand outside of the vehicle and swing the seat into a position to enable them to place the child directly therein in a face-to-face manner and then swing the seat back into place and lock it into a secure position. The child seat is secured to a seat support mechanism comprising a support bar pivotably connected to a hinge assembly that slides along a track assembly so as to maintain the car seat in a protected area within the vehicle when in the pivoted position. It becomes more difficult to place children into car seats as they get older and heavier and the present invention will increase the ease in which the child can be placed therein while relieving the stress on the guardian's back.
