Abstract

The invention relates to a medical rehabilitation nursing wheel chair, comprising a support frame, front wheels, rear wheels, a seat part and a backrest part, wherein the support frame comprises front wheel supports, rear wheel supports, side connecting rods, and a middle supporting frame. The lower ends of the front wheel supports are connected with the front wheels, the lower ends of the rear wheel supports are connected with the rear wheels, the side connecting rods are connected with the front wheel supports and the rear wheel supports, and the two side connecting rods are connected by the middle supporting frame. The seat part comprises cushion frames, and the upper ends of the front wheel supports are connected with the front ends of the cushion frames at the corresponding side in a rotatable way; the backrest part comprises a backrest frame, wherein the lower side of the backrest frame is rotatably connected with the rear end of the cushion frame at the corresponding side through a connecting piece; and an air spring is also connected between the cushion frames and the middle supporting frame of the support frame, and the air spring is used for adjusting the angle of the seat part relative to the horizontal plane and synchronously changing the angle between the backrest part and the seat part. The medical rehabilitation nursing wheel chair can adjust the positions of the backrest part and the seat part in order to make people keep the most comfortable status when people half lie down or lie down, which is favorable for the body rehabilitation of the user of the wheel chair.

Description

technical field [0001] The invention relates to a medical wheelchair. Background technique [0002] Existing wheelchairs basically consist of a vehicle frame, front wheels and rear wheels arranged on both sides of the vehicle frame, a seat portion and a backrest installed on the vehicle frame. Generally, the angle can be adjusted relative to the seat portion, that is, by changing the angle of the backrest relative to the seat portion, the user can lie on the wheelchair halfway to rest. In essence, this adjustment method only changes the angle of the backrest, but the angle of the seat relative to the ground is constant, that is, the user changes from a sitting position to a half-lying position, but the waist and upper body are tilted, so The tilting method can only suspend the fatigue of the user, and the parts below the waist cannot be completely relieved, especially when the wheelchair is used for rehabilitation training, this kind of wheelchair that can only adjust the b...
