    • A seat system has separate air bladders in the seat bottom and seat back. The seat bottom bladder is in fluid communication with the seat back bladder through a plurality of rigid interconnecting tubes, and valves in the tubes or orifice size can control flow rate of air exchange between the seat bottom bladder and the seat back bladder. A panel of resilient, compressible open cell foam extends in each of the seat bottom bladder and the seat back bladder. Through-holes in the foam panel permit accelerated air evacuation to the other bladder when the seat withstands a significant shock event. The vibration and shock attenuation characteristics of the seat are jointly provided by the panel spring force and the bladder air pressure.
    • 座椅系统在座椅底部和座椅靠背中具有单独的气囊。 座椅底膀胱通过多个刚性互连管与座椅靠背囊流体连通,管中的阀或孔尺寸可以控制座椅底膀胱和座椅靠背囊之间的空气交换流速。 弹性可压缩开孔泡沫的面板在每个座椅底膀胱和座椅靠背囊中延伸。 泡沫板中的通孔允许当座椅经受重大冲击事件时,可以将另一个膀胱的空气排出加速。 座椅的振动和冲击衰减特性由面板弹簧力和气囊气压共同提供。
