Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Referring to fig. 1-6, the present invention provides a chair structure, which includes: a seat frame 3, a seat cushion 2 and a backrest 1;

the chair frame 3 includes: the fixed frame and set up a plurality of bearing pipes 303 in the frame, the frame includes from last back support portion 301 that is used for installing back 1 that extends down and from the back to front respectively to the sunken setting and upwards establish the seatpad 2 support portion 302 that forms the S-shaped structure of protruding, a plurality of bearing pipes 303 interval sets up on seatpad 2 support portion 302 and a plurality of bearing pipes 303 are located same level, bearing pipes 303 are connected with seatpad 2 and are used for supporting seatpad 2.
