The invention discloses a liftable energy-absorbing base for an aircraft pilot's seat, which comprises a lower connecting seat and an upper connecting seat, and a scissor-type lifting mechanism is arranged between the two; the scissor-type lifting mechanism includes a first arm, the second arm and the lifting adjustment rod, the middle part of the first arm and the second arm is hinged, and the upper end of the first arm is provided with a bending structure; the lower end of the first arm is hinged with the lower connecting seat, and the upper end is connected with the The upper connecting seat is slidingly connected; the lower end of the second arm is slidingly connected with the lower connecting seat, and the upper end is hinged with the upper connecting seat; the lifting adjustment lever is used to adjust the distance between the first arm and the upper or lower end of the second arm, and the lifting adjustment An energy absorber is also arranged in the middle of the rod. The invention can provide a vertical energy-absorbing and buffering effect for the seat, and the driver can steplessly adjust the height of the seat without leaving the seat. The device is small in size and weight, and easy to install.
Description
technical field [0001] The invention relates to a lift adjustment mechanism of a seat, in particular to a liftable energy-absorbing base of an aircraft pilot's seat. Background technique [0002] With the rapid development of the aviation field, the comfort and safety of the driver's seat have drawn more and more attention from people. The new driver's seat has a multi-directional adjustment function, and the seat can be adjusted in various ways. Some seats even use an electric adjustment mechanism to realize the seat's lift. However, some general-purpose small aircraft have a small space, requiring the seat height of the driver's seat to be relatively low, and require the seat height to be adjusted without the driver's buttocks leaving the seat surface, and the requirements for dynamic impact performance are also relatively strict. [0003] The existing base equipped with an energy absorber has a relatively high seat surface height, and the energy absorber can be installed...
