The defect
Corp. Micro Bird Inc. (Micro Bird) is recalling certain 2011-2018 Micro Bird G5, MB-II, and T-series school buses, equipped with CE White/HSM SB11-30" series, standard, unbelted, school bus seats, or SB11-30" series school bus seats with lap belts only. The foam in the knee impact area of the lower seat back may not absorb enough impact in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 222, "School Bus Passenger Seating and Crash Protection."
The risk
If the seat foam does not absorb enough impact energy, it can increase the risk of injury in the event of a crash.
