摘要

An improved seating system that includes a seat back assembly ( 10 ) that is fabricated to include a seat back ( 12 ) with first and second wall portions ( 14,16 ), and which may include an integrated reinforcement structure ( 18 ). The seating system is capable of either or both of withstanding without rupture at least about 11000 Newtons in the direction in which the seat back ( 12 ) faces in a plane, parallel to the longitudinal centerline of the vehicle or, upon rapid acceleration up to at least about 20 g, substantially no fragmentation of the seat back with at least a 30 kg mass placed behind the seat back.
