Patent attributes
A chair back and seat assembly is revealed. The assembly includes a seat base having an assembly recess with two long locking hole on two side walls, and a back support which includes a connection portion on one end and a driving member at the connection portion and connected with locking bars of the connection portion. During assembly, a pull plate of the driving member is pushed by a recess opening of the assembly recess when the connection portion of the back support is mounted into the recess opening of the assembly recess. Thus the driving member is moved backward and driving the two pre-retracted locking bars to be protruding and further locked by the locking holes of the assembly recess. Thereby the assembly is completed easily and conveniently. The design also prevents the seat base and the back support from unexpected loosening while seated.
