ABSTRACT:
A chair includes an L-shaped backrest with a horizontal section engaged with an underside of a seat. An elongated slot is defined in an underside of the horizontal section. A spring assembly includes a knob with a screw extending through the elongated slot and threadedly engaged with the underside of the seat to thereby allow sliding movement of the screw relative to the elongated slot. A leg frame includes two arcuate legs and at least one transverse beam interconnected between the arcuate legs and received in an engaging groove in the seat and secured to two connecting rods, each connecting rod having two ends pivoted to the backrest and the seat, respectively. A a rearward pivotal movement of the backrest relative to the seat causes the seat to move upwardly and forwardly to thereby provide increased safety for the user.
