Thereby enabling the person to be in a zero-gravity fully supine position for resting a nap.
When the stretching device is switched between the sitting posture and the leisure posture, the piston rod of the force application part 13 is extended, the force application part 13 gives an outward driving force to the second force transmission rod 15 along the length direction of the seat frame 3, the first leg rod 16 and the second leg rod 17 rotate, so that the third leg rod 18 and the fourth leg rod 19 are driven to rotate, the knee supporting block 20 and the foot supporting rod 22 are unfolded outwards to be positioned in a straight line with the seat frame 3, and at the moment, the whole leg supporting component 4 is extended outwards to be opened, so that the foot is supported. When the piston rod of the force application member 13 is shortened, the motion tracks are opposite, and the whole leg support assembly 4 is contracted and folded back to the lower part of the seat frame 3, so that the state conversion is completed.
When the stretching device is switched between a zero gravity state and a leisure state, the piston rod of the driving part 12 extends to provide an outward driving force for the first transmission rod 14 along the length direction of the seat frame 3, the seat frame 3 rotates relative to the base frame 1 and moves towards one side far away from the backrest component relative to the base frame 1, and the backrest component rotates relative to the seat frame 3 under the driving of the linkage mechanism 5, so that the forward tilting of the seat frame 3 and the backward tilting of the backrest component are completed, and the complete state is converted. When the piston rod of the force application part 13 is shortened, the motion tracks are opposite, the seat frame 3 is reset, the backrest assembly tilts forwards, and the leisure state is recovered.
