The NHTSA recall affects 14,220 of the Chaperone seat models E9L692J, E9L692K, E9L692L and E9L692M that were manufactured from Sept. 1, 2010, through April 30, 2011. The recall is intended to address a defective rivet that attaches the harness adjuster to the car seat.

Britax said the harness adjuster can detach from the seat shell. This could result in a child not being properly restrained in the event of a crash, increasing the risk of injury or death.

Britax is expected to notify owners of these Chaperone seat models and provide them with repair kits free of charge. The safety recall and mailing of the kits is expected to begin in or about Feb. 6. Until then, any seats on which the harness adjuster has detached will be replaced.
