ABSTRACT:
A chair includes a seat frame, a seat movably mounted on the seat frame, a backrest pivoted to the seat frame, a reciprocating mechanism mounted under the seat frame to cause the seat to engage in a series of repeated up-and-down motions, and a reclining mechanism mounted under the seat frame to enable the backrest to be adjusted for reclining. The reciprocating mechanism has a transmission member which is driven by a motor and is provided with a contact portion in contact with the underside of the seat. The reclining mechanism includes a control lever for regulating the position of an actuation pin in a triangular hole of a position control plate such that the actuation pin serves to activate or deactivate a pressure release knob of a cylinder which is fastened at one end with the backrest.
