Abstract

A child seat including a tensioning mechanism for applying tension to a seat belt to more fully secure the child seat to a car seat is provided herein. The child seat includes a seat base defining a seat portion and a backrest portion and designed to receive an untensioned belt to secure the child seat to a car seat in an untensioned configuration. The child seat further includes a tensioning mechanism attached to the backrest portion and rotatable between a first position substantially adjacent to the backrest portion and a second position disposed therefrom. In the second position, the tensioning mechanism can receive a portion of the belt. In the first position, the tensioning mechanism is configured to apply tension to the portion of the received belt to secure the child seat to the car seat in a tensioned configuration. Methods of manufacturing child seats are also provided herein.

9. The child seat according to claim 7, wherein the locking mechanism comprises a latch configured to enable a user to translate the locking members from the extended position to the retracted position.

10. The child seat according to claim 9, wherein the latch defines two pockets that are configured to each receive a finger of a user, wherein the two pockets are configured to translate toward each other to cause the locking members to move from the extended position to the retracted position.

11. The child seat according to claim 7, wherein the seat base defines a ramp proximate each lock receiving portion, wherein the ramp is configured to engage and at least partially retract the locking members from the extended position to enable the tensioning mechanism to rotate from the second position to the first position.

13. The child seat according to claim 1, wherein the seat base defines padding positioned on and attached to the backrest portion and the seat portion so as to receive an occupant therein, wherein the tensioning mechanism is accessible and rotatable between the first position and the second position with the padding attached to the backrest portion.

14. The child seat according to claim 1, wherein the seat base is configured to receive the belt of the seat of the car such that the belt can be positioned around the backrest portion and seat portion and engaged with the buckle of the seat of the car without feeding the belt through a hole in the seat base.
