[0030] Deployment process:

[0031] Pulling the backrest adjustment handle 14 unlocks the backrest angle adjuster 9, allowing the backrest side panel 10 to be adjusted backward. Pulling the lift adjustment handle 15 unlocks the lift angle adjuster 5 via the zipper assembly, and simultaneously the lift gas spring 12 lifts the front cross tube 18 of the seat cushion, allowing the seat side panel 2 to rotate around the rear cross tube 19 of the seat cushion, thus raising the seat cushion. Pulling the leg rest unlock handle 16 unlocks the leg rest restriction lock 21 via the zipper assembly, allowing the restriction wire 20 to disengage, and simultaneously the leg rest gas spring 11 pushes out one side of the movement mechanism of the leg rest assembly 1, extending the leg rest. Pulling the slide rail unlock handle 17 unlocks the slide rail assembly 13 via the zipper assembly, allowing the seat cushion and backrest to slide backward via the slide rail assembly 13. Through these four actions, the seat achieves a zero-gravity state.

[0032] Reset procedure:

[0033] Pull the backrest adjustment handle 14 to unlock the backrest angle adjuster 9, allowing the backrest side panel 10 to be adjusted forward. Pull the lift adjustment handle 15 to unlock the lift angle adjuster 5 via the zipper assembly, while simultaneously pressing down the seat cushion side panel 2, allowing it to rotate around the rear cross tube 19 of the seat cushion, compressing the lift gas spring 12 and restoring it to its lowest position. Press down the leg support assembly 1, causing one side of its motion mechanism to move back, while simultaneously compressing the leg support gas spring 11 until the limiting wire 20 enters the leg support limiting lock 21, locking the leg support assembly 1 and restoring it to its retracted state. Pull the slide rail unlock handle 17 to unlock the slide rail assembly 13 via the zipper assembly, allowing the seat cushion and backrest to slide forward via the slide rail assembly 13. Through these four actions, the seat is restored to its normal use state.
