目的研究床屏设计对睡眠倚靠舒适度的影响。方法从人机3-．程学角度，对床屏尺寸、材料及人体支撑点对倚靠舒适性的影响进行探讨。结论舒适的床屏需保持脊柱的自然曲度，背部压力的均匀分布，倚靠姿势的舒适转换，必要时可增加调节功能。在床屏尺寸上，高度一般在920～1020mm，角度一般在1000～120°，若床屏高于1050mm，角度大于110°，应配有头靠。在床屏材料上，软包床屏有海绵缓冲层，相比木质、金属及竹藤床屏，倚靠舒适性更高。在支撑点上，腰部位置（床垫以上230～250mm）增加凸起，背部最大压力点在肩胛骨及腰椎骨位置最佳。在床屏形状上，内凹形床屏相比扁平、圆弧及半圆形床屏，舒适性更高；S形床屏虽是以人体脊柱形态曲线来设计的，但其形状反而会限制背部活动。

英文摘要：

Objective It studied the influence of bed screen design on sleep relying comfort. Methods It discussed the influence of bed screen size, materials and body supporting point on relying comfort from the perspective of ergonomics. Conclusion The bed screen needs to keep the spine＇ s natural curvature, uniform distribution of back pressure, relying posture comfort conversion, may be appropriate to increase the adjustable function when necessary.The bed screen height is generally 920 - 1020 mm.The bed screen angle is generally 100~ - 120~ .If the bed screen is higher than 1050 mm, angle greater than 110~, the bed screen should add the headrest support functions.The back more comfort on soft pack than wood, metal, rattan bed screen.If the filling layer with memory foam and latex, the back pressure can relieve effectively.The bed screen should increase support in waist position which above the bad surface 230-250 mm.The shape of concave is better than flat, circular and semicircular bed screen.The S-shape bed screen which design as human vertebral curve will limit back activity.
