The invention discloses a floor deformation isolation device and an aero seat. The device comprises a transverse supporting rod and an isolation mechanism. The transverse supporting rod is located on the lower portion of the aero seat, and the two ends are connected with seat components. The isolation mechanisms are distributed at the two ends of the transverse supporting rod and comprise sliding blocks in sliding fit with the sliding rails, pitching stabilizing blocks and rolling stabilizing blocks, the transverse supporting rod is sleeved with the pitching stabilizing blocks and the rolling stabilizing blocks in a matched and empty mode, the pitching stabilizing blocks are fixedly connected with the seat component at the end where the pitching stabilizing blocks are located through shearing pieces, and the shearing pieces can be disconnected when bearing certain shearing force. The lower portion of the pitching stabilizing block is hinged to the sliding block through a rotating shaft, the lower portion of the rolling stabilizing block is connected with the sliding rail in a tensioning mode through a tension piece, and the tension piece is disconnected when bearing certain tensile force. The device can ensure that the aero seat is stable and does not shake in a normal state, can be adjusted front and back, can prevent the deformation effect from being upwards transmitted to the upper structure of the aero seat when an aircraft floor deforms, and ensures that the aero seat still has a falling collision protection function.
本发明公开一种地板变形隔离装置及航空座椅,该装置包括横撑杆和隔离机构;横撑杆位于航空座椅下部且两端分别与座椅构件连接;隔离机构分布在横撑杆两端,包括滑动配合在滑轨上的滑块以及配合空套在横撑杆上的俯仰稳定块和滚转稳定块,俯仰稳定块通过剪切件与所在端座椅构件固定连接,剪切件能在受到一定剪切力时断开连接,俯仰稳定块下部通过转轴与滑块铰接,滚转稳定块下部通过拉力件与滑轨拉紧连接,拉力件在受到一定拉伸力时断开连接。该装置能够在正常状态下确保航空座椅稳定无晃动、能前后调节,在飞机地板变形时能避免变形作用向上传递给航空座椅的上部结构,确保了其仍具备坠撞防护功能。
