摘要/Abstract

摘要： 摘要：通过对现有坐姿矫正产品工作原理及其局限性的分析，提出了一种全新的坐姿矫正方式，即利用人体就坐时的重力，通过四杆机构形成使骨盆前倾的扭矩，以帮助人们轻松地保持健康坐姿；通过生物力学实验获得坐姿状态下人体的外力矩与骨盆倾角的关系，根据实验结果设计和制作了坐姿矫正装置，并通过实验验证了所设计装置的有效性.结果表明，所设计的坐姿矫正装置可以使人们得到最佳坐姿，尤其是在腰部肌肉放松的条件下能够保持理想的骨盆倾角.

Abstract: Abstract： The working principles and limits of existing orthotic devices for sitting posture were analyzed. A novel way to help users easily maintain healthy sitting posture was proposed. By using fourbar linkage, body weight was transformed into torques to rotate the pelvis. A biomechanical experiment was conducted to acquire the relationships between external torques and rotation angles of the pelvis while sitting. Based on the experimental results, the prototype of the gravitydriven orthotic device was built. Its feasibility was proved by a verification experiment. The results showed that this device could help users easily maintain ideal pelvic incidence while relaxing low back muscles.
