摘要： A pressure balanced torsion system for use in a backrest and the like comprises a plurality of pairs of pressure bearing plates (12, 13) coupled to a torsion spring means. The torsion spring means (14, 15) is pivotally mounted to a support back plate (25). When an external pressure is exerted onto the pressure bearing plates (12, 13) by a human body resting against them, the counter reactive force generated by the torsion spring (14, 15) in the system will cause both pressure bearing plates (12, 13) to push against the human body until the counter reactive force is balanced in both pressure bearing plates; thus providing a balanced counter pressure against the human body to provide a uniform support therefor.
