It is not easy for others to help the user to wash their hair.

The purpose of the present invention is to provide a structure that can have better back angle adjustment and support positioning stability and safety.

The creation includes a main frame body, a chair back, and two telescopic rods. The main frame body has two opposite side frames, and the two side frames have two cross frame connections, and the two horizontal frames can support the toilet seat cushion, and The two side frames have front and rear rod portions, and the rear rod portion has an upper straight section, and the upper straight section is laterally bent and supported by the lower vertical section, and the lower vertical section is disposed downwardly from the rear side of the support section, and is disposed on the upper vertical section. The first upper pivoting portion is provided with a first lower pivoting portion.

The second lower pivoting portion is disposed at a lower side of the second side of the chair back to be pivotally connected to the first upper pivotal portion of the main frame body, and the second upper pivotal portion is disposed at the center; and the two telescopic rods are respectively disposed on the back of the chair The third upper and lower pivoting portions are respectively disposed on the side, the upper portion and the lower portion, and the third upper pivoting portion is pivotally connected to the second upper pivoting portion of the seat back, the third lower pivoting portion and the main frame supporting portion The first lower pivoting portion is pivotally connected.

The telescopic rod can have a first and a second rod plug combination, and a plurality of positioning holes are arranged in the first rod portion, and the other second rod portion is provided with a jack, and the first positioning portion of the first rod portion can be appropriately positioned. The position of the jack of the two-bar portion is correspondingly inserted and inserted into the tip; and the second rod portion can be provided with an elastic button, and the elastic button can be combined with a suitable positioning hole of the first rod portion to position the length of the telescopic rod; In addition, the telescopic rod can be a pneumatic rod, a hydraulic rod or a screw driven by a motor, and the telescopic length can be adjusted in a stepless manner.

When the occupant is lying on the back of the chair, the occupant can be supported by the two side telescopic rods evenly, which can have better support stability and does not cause the center of gravity to shift to one side.

The creation can make the back of the chair recline to a large angle to facilitate bathing or lying rest, and can be supported by the two side telescopic rods evenly when lying down, and the lateral supporting section of the main frame body can support the weight of the lying down, which can be greatly The support strength is increased, and the support section extending backward can increase the support area, and can prevent the upper side of the toilet seat from falling backwards when lying backwards, so that the use safety can be better.

And the two lateral frames 12 can support the toilet seat cushion 13, and the two side frames 11 have front and rear rod portions 111, 112. The rear rod portion 112 has an upper vertical portion 113, and the upper vertical portion 113 is downwardly oriented. The support section 114 is laterally bent, and the lower upright section 115 is disposed downward from the support section 114, and the wheel body 14 is disposed below the front pole portion 111 and below the upright section 115 below the rear pole portion 112, and is further disposed on the upper upright section 113. The first upper pivoting portion 116 is provided with a first lower pivoting portion 117. The first lower pivoting portion 117 has two parallel pivoting pieces 118, and the pivot holes 119 are disposed on the two parallel pivoting pieces 118.

A second lower pivoting portion 21 is pivotally connected to the first upper pivoting portion 116 of the main frame body 1 and a second upper pivoting portion 22 is disposed at the center.

The second telescopic rods 3 are respectively disposed on the two sides of the seat back 2, and the third upper and lower pivoting portions 31 and 32 are respectively disposed above and below, and the third upper pivotal portion 31 and the second upper pivotal portion 22 of the seat back 2 are respectively disposed. The third lower pivoting portion 32 is pivotally connected to the first lower pivoting portion 117 of the supporting portion 114 of the main frame body 1 and has a pivot hole 321 at the third lower pivoting portion 32. The two pivoting pieces 118 of the pivoting portion 117 are pivotally connected by the pivoting holes 322 and the pivot holes 119 and 321 of the third lower pivoting portion 32. The telescopic rod 3 has the first The two rod portions 33 and 34 are inserted and combined, and a plurality of positioning holes 331 are disposed in the first rod portion 33, and the other second rod portion 34 is provided with the insertion hole 341, and the corresponding positioning holes 331 and the second portion of the first rod portion 33 are provided. The position of the insertion hole 341 of the rod portion 34 is correspondingly positioned and then inserted through the insertion tip 35.
