Abstract

A molded booster seat has an upper back portion and a lower seat portion connected to an integral hinge. The upper and lower portions are pivoted about the integral hinge toward each other to form a rigid body, and cooperate to form a plurality of mortise and tenon joints. The upper and lower portions are locked in the rigid body configuration by a pair of side plates and a pair of locking rods extending through the seat between the side plates. The booster seat also includes an adjustable belt positioner that is configured to move between a plurality of different adjustments. The upper and lower positions are located to accommodate the fall range of sizes of children of a child sitting in the booster seat. The booster seat further includes indicia for indicating height limitations of a child sitting in the seat. The indicia can be labels attached to a seat cover disposed on the seat. Appropriately, the positions of the adjustable belt positioner can be located to accommodate children whose size falls within the indicated size limitations.

4. The child'"'"'s car seat of claim 3, wherein said shoulder strap retaining means includes an elongate flexible member having a first end fixed to said moveable portion and an opposite, second end releaseably coupleable to said moveable portion, the shoulder strap being retainable between said flexible member and said moveable portion when said second end is coupled to said moveable portion.

5. A shoulder belt positioner for use on the back portion of a child'"'"'s car seat to position a shoulder belt at an appropriate height for a child occupant of the seat, said shoulder belt positioner comprising:

a fixed portion mountable to the seat'"'"'s back portion, said fixed portion including a rack;

a moveable portion slidably mounted to said fixed portion for movement between an upper limit and a lower limit to accommodate different sized children, said moveable portion including a cover plate having means for locking the cover plate in position relative to the rack; and

means mounted to said moveable portion for releaseably retaining the vehicle'"'"'s shoulder strap.

6. The seat of claim 5 wherein the locking means includes a plurality of locking detents formed on the rack and a shoulder formed on the cover plate for engaging the detents to lock the cover plate to the rack at one of a plurality of predetermined positions.

7. A shoulder belt positioner for use on the back portion of a child'"'"'s car seat to position a should belt at an appropriate height for a child occupant of the seat, said shoulder belt positioner comprising:

a fixed portion mountable to the seat'"'"'s back portion;

a moveable portion slidably mounted to said fixed portion for movement between an upper limit and a lower limit to accommodate different sized children; and

means mounted to said moveable portion for releaseably retaining the vehicle'"'"'s shoulder strap, said shoulder strap retaining means including an elongate flexible member fixed at a first end to said moveable portion and releaseably coupled at an opposite, second end to said moveable portion.

8. A method for manufacturing a child'"'"'s seat comprising the steps of:

molding a unitary shell having an upper back portion and a lower seat portion hingedly connected by an integral hinge, one of the upper and lower portions having a mortise and the other of the upper and lower portions having a tenon configured to engage the mortise;

pivoting the upper and lower portions toward each other about the integral hinge to join the mortise and tenon.

9. The method of claim 8 further including the step of locking the mortise and tenon joint to prevent further movement about the integral hinge.

10. The method of claim 9 wherein the seat further includes a hole extending through the mortise and tenon joint and the locking step includes the step of inserting a locking rod into the hole.

11. The method of claim 10 wherein passage of the locking rod through the mortise and tenon joint forms the hole.

12. The method of claim 9 wherein the locking step includes the step at inserting locking rods into the joint.

13. The method of claim 8 wherein one of the upper and lower portions further includes pair of mortises in spaced-apart relation and the other of the upper and lower portions further includes a pair of tenons in spaced-apart relation the pair of tenons being aligned to engage the pair of mortises.

14. A seat comprising:
