Claims34
A child restraint comprising
- a juvenile seat including a hollow seat shell having a seat bottom and a seat back extending upwardly from the seat bottom and cooperating with the seat bottom to define an enclosed interior region of the hollow seat shell and a rigidifying truss located in the enclosed interior region of the hollow seat shell and coupled to the hollow seat shell to lie in a stationary position in the interior region,
- a headrest mounted for up-and-down movement on the rigidifying truss relative to the seat back,
- a headrest-height controller arranged to adjust the height of the headrest on the rigidifying truss relative to the seat bottom, wherein the headrest-height controller includes a headrest lock and a headrest-lock release, the headrest lock includes a rod receiver coupled to the rigidifying truss and located in the interior region of the hollow seat shell and a headrest-retainer rod arranged to lie and move in the interior region relative to the rod receiver between a locked position engaging the rod receiver to retain the headrest in a selected position on the rigidifying truss to establish the elevation of the headrest above the seat bottom and an unlocked position disengaging the rod receiver to free the headrest for up-and-down movement relative to the rigidifying truss and the seat back to establish a new elevation of the headrest above the seat bottom, the headrest-lock release is coupled to the headrest to move therewith relative to the rigidifying truss and seat back and mounted for movement on the headrest by a caregiver, the headrest-retainer rod is coupled to the headrest-lock release to move therewith between the locked and unlocked positions in response to movement of the headrest-lock release relative to the headrest by a caregiver, and wherein the rigidifying truss includes a first load-receiver rail, the headrest includes a first load-transfer flange maintained in mating engagement with the first load-receiver rail of the rigidifying truss during up-and-down movement of the headrest on the rigidifying truss.
A child restraint comprising
- a juvenile seat including a hollow seat shell having a seat bottom and a seat back extending upwardly from the seat bottom and cooperating with the seat bottom to define an enclosed interior region of the hollow seat shell and a rigidifying truss located in the enclosed interior region of the hollow seat shell and coupled to the hollow seat shell to lie in a stationary position in the interior region,
- a child-restraint harness coupled to the juvenile seat and configured to restrain a child seated on the seat bottom, and
- a headrest coupled to the child-restraint harness and mounted for up-and-down movement on the rigidifying truss relative to the seat back, and wherein a first load-transfer flange included in the headrest is arranged to engage and slide on a first load-receiver rail included in the rigidifying truss during up-and-down movement of the headrest on the rigidifying truss and the headrest is configured to provide means for engaging the child-restraint harness to receive a load applied to the child-restraint harness by a seated child seated and restrained on the seat bottom of the juvenile seat during movement of the seated child relative to the juvenile seat in response to a sudden stop of a moving vehicle carrying the juvenile seat and for transferring the load from the headrest to the rigidifying truss located in the interior region of the hollow seat shell via a load-transfer path established by mating engagement of the first load-transfer flange included in the headrest and the first load-receiver rail included in the rigidifying truss.
A child restraint comprising
- a juvenile seat including a hollow seat shell having a seat bottom and a seat back extending upwardly from the seat bottom and cooperating with the seat bottom to define an enclosed interior region of the hollow seat shell and a rigidifying truss located in the enclosed interior region of the hollow seat shell and coupled to the hollow seat shell to lie in a stationary position in the interior region,
- a headrest mounted for up-and-down movement on the rigidifying truss relative to the seat back,
- a headrest lock including a rod receiver and a headrest-retainer rod, wherein the rod receiver is coupled to the rigidifying truss and formed to include a series of rod-receiving notches, each rod-receiving notch is located at a different elevation above the seat bottom, the headrest-retainer rod is arranged to lie and move in the interior region of the hollow seat shell relative to the rod receiver between a locked position extending into one of the rod-receiving notches formed in the rod receiver to retain the headrest in a selected position of the rigidifying truss to establish the elevation of the headrest above the seat bottom and an unlocked position disengaging the rod-receiving notches formed in the rod receiver to free the headrest for up-and-down movement on the headrest by a caregiver, and
- wherein the rigidifying truss includes a first load-receiver rail, the headrest includes a first load-transfer flange maintained in mating engagement with the first load-receiver rail of the rigidifying truss during up-and-down movement of the headrest on the rigidifying truss.
