The adapter piece 6 and the plane of the two support pieces 1 have a certain angle, and the adapter piece 6 can be forced to rotate within the allowable range of the accommodating groove 41.

When the fabric 2 in the middle of the supporting piece 1 is stressed, the fabric 2 can generate an inward pulling force on the supporting piece 1, at the moment, the supporting piece 1 can apply an upward rotating force on the connecting piece 6, so that the connecting piece rotates upward, and the distance between the two supporting pieces 1 is reduced; when the fabric 2 is stressed to generate inward pulling force on the support member 1, the support member 1 can also receive downward pressure, the support member 1 can generate downward pressure on the support arm, at the moment, the support member 1 can generate downward pressure on the connecting member 6, when the connecting member 6 is stressed, the connecting member can rotate along the rotating shaft device 62, the distance between the support members 1 is slightly expanded, and the tightening degree of the fabric 2 is increased. The pressure that support piece 1 receives is greater than the pulling force of surface fabric 2 to support piece 1, so, adaptor 6 finally can turn into the reverse tension of level with support piece 1's pressure, deepens the tight state of surface fabric 2, can not lead to surface fabric 2 to cave in too deeply, influences user's comfort level and experiences. It can be understood that the angles between the support arm and the plane where the support member 1 is located and between the adaptor member 6 and the plane where the support member 1 is located can be adjusted according to actual conditions, and actual functional requirements can be met.

After being connected through pivot means 62, mounting hole between holding tank 41 and the adaptor 6, can also set up the screw in one side that adaptor 6 and holding tank 41 laminated, correspond on the holding tank 41 and set up the bolt for adaptor 6 revolutes the length restriction that the turned angle of pivot means 62 received the bolt, makes the connection between adaptor 6 and the support arm stable. It will be appreciated that there are a number of ways to limit the angle of rotation of the adaptor 6 to be able to function satisfactorily.

Referring to fig. 1 and 2, a telescopic device may be disposed between the base 3 and the supporting device 4, and an adjusting rod is disposed to control the telescopic length of the telescopic device, so as to adjust the height of the carrying surface of the seat by adjusting the overall length of the telescopic device, thereby being suitable for different users or use scenes. Base 3 can set up many with support and ground steady support state, the embodiment of the utility model provides an in, adopt five supports and ground to form stable bearing structure, realize diversified support. When one of the brackets is suspended, the other four brackets can still ensure the supporting stability of the base 3. After the telescopic device is installed at the central part of the supporting device 4, an anti-collision device can be arranged at the upper end of the supporting device 4, so that potential safety hazards to articles, users and the like on the seat when the stress of the telescopic device exceeds the capability range are avoided.

As an embodiment, the surface of the supporting device 4 corresponding to the side of the fabric may be configured optimally, so that when the fabric is cut apart, the upper surface of the supporting device 4 may be directly or indirectly used to meet the functional requirements of the seat without a substitute. As another embodiment, an elastic supporting belt can be arranged between the two symmetrical adapters 6, the distance between the two supporting pieces 1 can be tensioned, so that the fabric 2 can elastically retract, further, a certain gravity can be borne, the situation that the seat cannot be used after the fabric 2 is accidentally damaged is avoided, and the elastic supporting belt can be temporarily used as a cushion to continue to fulfill the function of the fabric 2.

Referring to fig. 1 and 2, the overall structure of the supporting member 1 may be configured as an "L" shape, the transverse portion may be used as a seat cushion, and the vertical portion may be used as a backrest. The bending part of the supporting member 1 may be provided with a plurality of bends, as shown in the supporting frame 1 in fig. 1 or fig. 2. Set up many bending on support piece 1, can improve single support piece 1 elasticity on vertical, improve user's use and experience, simultaneously, many places are buckled and can also be kept single support piece 1 hardness on horizontal, ensure that surface fabric 2 can be complete open, tighten. A backrest connecting piece 5 can be arranged between the two supporting pieces 1 at the backrest, and two ends of the backrest connecting piece 5 are fixedly connected with one supporting piece 1 respectively, so that the distance between the supporting pieces 1 at the backrest can be determined by the backrest connecting piece 5 and is not changed any more.
