The two extending portions 121 of the backrest tube 12 are respectively hinged and fixed to the rear ends of the left and right

seat frame tubes

115 and 116 at corresponding positions by a hinge 30.

In this embodiment, the hinge 30 is composed of two connecting pieces, the two connecting pieces clamp an extending portion 121 of the backrest tube 12 and the rear end of the corresponding left seat frame tube 115 or right seat frame tube 116, and one end of the two connecting pieces is pivoted on the extending portion 121, and the other end is pivoted on the rear end of the left seat frame tube 115 or right seat frame tube 116, so that the extending portion 121 of the backrest tube 12 can be unfolded to be approximately perpendicular to the base frame 11 to serve as the backrest of the base frame 11; and the extension part 121 of the backrest tube 12 can be folded above the base frame 11, and the folded connecting part 122 can be used as a handle, so that the carrying is convenient.

The armrest frame 13 includes two support tubes 131 and two armrests 132 disposed opposite to each other, wherein one end of the support tube 131 is pivotally connected to the middle of the left seat frame tube 115 or the middle of the right seat frame tube 116, the other end of the support tube 131 is pivotally connected to one end of the armrest 132, the other end of the armrest 132 is pivotally connected to an extension 121 of the backrest tube 12, and a linked deformable quadrilateral mechanism is formed among the backrest tube 12, the support tube 131, the left seat frame tube 115 or the right seat frame tube 116, and the armrest 132, so that the armrest frame 13 can be synchronously unfolded or folded along with the backrest tube 12.

In this embodiment, the two supporting tubes 131 may be independent tubes as shown in fig. 4, or two opposite tube portions of a U-shaped tube as shown in fig. 1 to 3, wherein preferably the two supporting tubes 131 are two tube portions of a U-shaped tube arranged opposite to each other, and the two supporting tubes 131 are two tube portions of a U-shaped tube arranged opposite to each other, so as to not only support the handrail 132 more stably, especially have a good stabilizing effect on lateral forces in the left-right direction, but also achieve synchronous folding or unfolding of the two handrails 132.
