    摘要： A reclinable office chair includes a reclination adjustment unit coupled to a bottom base disposed at the bottom of the office chair and having an angle limiting element disposed below and spaced apart from a connecting element abutting against carrying elements. When a user sitting on the office chair tilts the office chair in a predetermined direction, the connecting element and the carrying elements, whose movement is restricted by a rim of the bottom base, are stopped from tilting further as soon as the angle limiting element tilts to an extent to come into contact with the rim, not only allowing the office chair in operation to be tilted within a predetermined safety range in any direction, but also enhancing the anti-slip effect which takes place between the office chair and the floor.

    摘要： A lower-back supporting device of a chair includes: a backrest panel frame; a separately formed and elastic backrest panel mounted to the backrest panel frame, and at least one movement-limiting unit extending from a predetermined area of each of two corresponding inner lateral sides of the backrest panel frame and optionally arranged at a predetermined spacing. The bilaterally provided movement-limiting units clamp predetermined sections of a peripheral portion of the backrest panel and can be displaced vertically in order for the backrest panel to form a forwardly protruding lower-back supporting area at a predetermined height and to be leaned on elastically.

    摘要： A height-adjustable handrest has constituent components describe below. A middle bar element is inserted into a handrest external bar and has an internal space for containing a spring and an inner bar element. The handrest external bar is enclosed by a support unit with an upper end pivotally coupled to a press element. The press element has one end abutting against the inner bar element and has the other end protruding under an upward thrust from the spring. A pin passing through slots formed at the handrest external bar to penetrate oblong holes disposed at the inner bar element and the middle bar element, respectively. When pressed, the press element drives the inner bar element to move downward, thereby moving the pin upward along the inclined oblong hole of the inner bar element, compressing the spring downward, and moving the pin into a longitudinal channel of the handrest external bar.

    摘要： A chair backrest panel positioning device includes a backrest panel frame and a backrest panel. The backrest panel frame has a hollow configuration, is formed along the rear side of the seat of a chair, and has two upper lateral portions configured for retaining predetermined portions of the backrest panel respectively. The backrest panel is separately formed, may or may not conform in shape to the backrest panel frame, and features proper elasticity. The backrest panel frame further has two lateral portions which are at a predetermined height and are configured for clamping the corresponding areas of the backrest panel respectively. Once mounted to the backrest panel frame, the backrest panel can be leaned on elastically.
