Patent ID: 8104829

Claim:
A juvenile motion-inhibitor system comprising: a juvenile vehicle seat; an air-conveyance cushion associated with the juvenile vehicle seat, wherein the air-conveyance cushion includes a deflatable bladder filled with air, an inflatable bladder, and an air-transfer bridge coupled in fluid communication to a first chamber formed in the deflatable bladder and to a second chamber formed in the inflatable bladder to provide channel means for conveying air from the first chamber in the deflatable bladder into the second chamber in the inflatable bladder to inflate the inflatable bladder in response to application of a bladder-deflating force to the deflatable bladder during exposure of the juvenile vehicle seat to an external impact; wherein the air-conveyance cushion further includes a one-way valve located in the channel means and associated with both of the first and second chambers and the one-way valve is configured to provide means for preventing reverse flow of air from the second chamber formed in the inflatable bladder into the first chamber formed in the deflatable bladder after the inflatable bladder has been inflated using air conveyed from the first chamber in the deflatable bladder; and wherein the deflatable bladder is arranged to lie in a position on an inner face of the seat back and to lie between the seat bottom and a lower extremity of the inflatable bladder.
