The leg rest driving mechanism 7 is installed between the leg rest 4 and the seat frame 2, and is one for driving the leg rest 4 to turn over relative to the seat frame 2. The two armrests 8 are respectively pivoted on two sides of the seat frame 2, and the armrests 8 can be provided with control switches for controlling the multi-posture seat to be switched between different states. The transmission mechanism 9 is installed between the backrest frame 3 and the armrests 8, and is divided into two groups, which correspond to the two armrests 8, and the transmission mechanism 9 includes: a first transmission lever 9A and a second transmission lever 9B. The first end of the first transmission rod 9A is hinged on the backrest frame 3, the second end of the first transmission rod 9A is hinged on the first end of the second transmission rod 9B, and the second end of the second transmission rod 9B is connected on the handrail 8.
Referring to fig. 5 and 6, a user can control a control switch (not shown) on the armrest 8 to switch the multi-position seat between the sitting position, the prone position, and the standing position. Referring to fig. 5, the armrest 8 is rotatable relative to the seat frame 2 to a seating position for facilitating a user's grip in a seating position (where the grip portion of the armrest extends forward and rearward) and a prone position for facilitating a user's grip in a prone position (where the grip portion of the armrest extends upward and downward). Specifically, referring to fig. 5, the multi-posture seat is in a sitting posture by the backrest frame 3 being turned upward and the leg rest 4 being turned downward, and is in a lying posture by the backrest frame 3 being turned downward and the leg rest 4 being turned upward. When the backrest frame 3 is switched between the upward turning state and the downward turning state, the transmission mechanism 9 drives the handrail 8 to be correspondingly switched between the sitting posture holding position and the lying posture holding position.
