The invention provides a horizontal keeping armrest structure which comprises a backrest framework and an armrest assembly, armrest mounting supports are fixedly arranged at the two ends of the backrest framework, the two sides of the rear end of the armrest assembly are hinged to the armrest mounting supports through armrest rotating shafts, and the horizontal keeping armrest structure further comprises a horizontal keeping mechanism. The horizontal keeping mechanism can limit the armrest assembly to turn over between a horizontal opening state and a horizontal closing state, and when the backrest framework turns over within a designed use angle range, the horizontal keeping mechanism can enable the opened armrest assembly to be kept in a horizontal state all the time. By means of the horizontal keeping mechanism, overturning limiting of the armrest assembly can be achieved, when the backrest framework overturns within the designed use angle range, under the condition of the dead weight of the armrest assembly, an armrest limiting shaft of the armrest assembly can rotate around the front limiting position of an arc-shaped limiting groove, and the armrest assembly can rotate around the front limiting position of the arc-shaped limiting groove. The opened armrest assembly is always kept horizontal in the overturning process of the backrest framework, and flexibility and practicability of the seat armrest are effectively improved.

    本发明提出了一种水平保持扶手结构,包括靠背骨架和扶手总成,靠背骨架的两端固设有扶手安装支架,扶手总成的后端两侧通过扶手旋转轴铰接于扶手安装支架上,还包括水平保持机构,水平保持机构能限定扶手总成在水平打开状态与关闭状态之间翻转,且当靠背骨架在设计使用角度范围内翻转时,水平保持机构能使打开后的扶手总成始终保持水平状态。本发明通过水平保持机构,即能实现扶手总成的翻转限位,且当靠背骨架在设计使用角度范围内翻转时,扶手总成在自重的条件下,其扶手限位轴会绕着弧形限位槽的前极限位置自转,使得打开后的扶手总成在靠背骨架翻转过程中始终保持水平,有效提高了座椅扶手的灵动性和实用性。
