Abstract
The utility model discloses a chair capable of adjusting angle of a backrest, comprising two side frames (100), a sitting plate (200), a backrest (300) and a supporting mechanism (400). Each side frame (100) comprises a front leg (110), a sitting frame (120) and an armrest (130). The sitting plate (200) is fixedly connected between the two sitting frames (120). The middle part of the backrest (300) is hinged between the rear parts of the two armrests (130) and is arranged behind the sitting plate (200). The supporting mechanism (400) comprises two pivoted rods (410) and a supporting rod (420); the two pivoted rods (410) are hinged with the two sitting frames (120) respectively; two ends of the supporting rod (420) are hinged with two pivoted rods (410) respectively; two ends of the supporting rod (420) are leaned on the two sitting frames (120); and the supporting rod (420) is fixedly connected with the lower end of the back surface of the backrest (300). The chair has the advantages that the armrests, the sitting frames, the backrest and the pivoted rods form a four-rod folding mechanism so that the angle of the backrest can be adjusted and can be kept by leaning two ends of the supporting rod on the sitting frames.
