By adopting the technical scheme, the invention has the following beneficial effects:
(1) The invention realizes the adjustment of sitting postures, semi-lying states and full-lying states of the seat, the seat translation motor drives the cushion framework to move forwards and backwards, the cushion framework moves forwards and backwards through the three-stage sliding rails and the racks, the three-stage sliding rails occupy small space, and meanwhile, the distance of the cushion framework moving forwards and backwards is long; the sliding groove is arranged, and the jerk value of the roller in the direction perpendicular to the three-stage sliding rail is constant in the rising section of the roller, so that the discomfort of passengers caused by obviously accelerating the speed of the backrest framework when the seat is adjusted from a half-reclined state to a fully reclined state is avoided; and the roller rises simultaneously when moving forward along the spout for the cushion skeleton rear end risees when the state of lying entirely, makes the cushion skeleton the angle under position of sitting, semi-lying and the state of lying entirely more comfortable, has improved the comfort level of seat and seat adjustment process.
(2) When the cushion framework moves back and forth through the connecting rod I and the connecting rod II, the backrest framework is driven to move downwards, and the backrest framework moves forwards when moving downwards, so that the backrest framework basically moves downwards vertically in the process of adjusting the state of the seat, the space at the rear side of the seat is not occupied, and the occupied space is small.
(3) The leg support framework is adjusted through the leg support motor, so that the structure is simple, and the operation is convenient.
(4) When the electric adjustment of the seat is problematic, the pins are pulled out through the steel wire ropes, so that the leg support motor and the seat translation motor stop running, the leg support framework, the seat cushion framework and the backrest framework are manually adjusted, the sitting posture, the semi-lying state and the full-lying state of the seat are adjusted, the operation is simple, and the use is convenient; and the steel wire rope is fixed and protected through the supporting pad or the rope sleeve, so that the operation of other structures of the seat is prevented from being influenced.
(5) The adjustment of the headrest framework is realized through the damping hinge, the damping guide rail, the linear sliding groove, the sliding block and the limiting block, and the comfort level of the headrest part of the seat is improved.
