一种矫正坐姿的桌椅
本专利技术涉及学习、办公用的桌椅,特别是一种能矫正坐姿的桌椅。
技术介绍
不良的坐姿会引起骨骼和腰椎疼痛等多种疾病,驼背是一种常见病、多发病,是由于腰椎间盘发生退行性病变引起的,发病人群多是机关工作人员或常年从事文案工作的人员,由于常年坐在椅子上工作,缺乏腰部的运动,造成腰椎间盘退行性病变,当突出部位压迫神经时,会引起腰、腿疼痛等多种临床症状,久而久之脊椎弯曲变驼,严重时患者无法自行行走,甚至丧失劳动和工作能力。另外,不良的坐姿会引发防近视等疾病,现有的方式主要是在课桌上加护栏等用强制性措施,迫使孩子们保持正确的坐姿,并利用一根限位杆来限制孩子们的弯腰幅度,而后缩短椅子与桌子间的距离,从而使学生保持正确的坐姿。现有的医学保健椅,在椅子前面安装一个可以分力的支点,胸部的支撑让坐立者的脊柱和背部肌肉自主前倾。坐立着的骨盆可以支撑臂部压力,简洁缓解背部的压力,让背部曲线趋于正常水平。肘部的支撑减轻了颈肩的疲劳,但是价格昂贵,并且胸腔靠在胸腔支架上工作时,容易有压迫感和疲劳。胸腔支架也不能当作靠背等别的用途,即使是自然的坐姿,固定20分钟以上对脊椎仍然 ...
