The Study Of Lumbar Disease Chair Comfort Design

There are many health problems in modern office sedentary working state.While,waist carries the most weight upper body,every day in addition to supine sleep,waist two third times withstand more than sixty percent of the human body and bear the weight of oppression,while sitting in the waist under pressure is more than 1.5 times when standing.More and more patients with lumbar disease,the incidence rate is rising year by year and tend to be younger,Various lumbar diseases have become one of the most common pain problems after a common cold in pain incidence,the patients with long-term pain in the lumbar spine,seriously affecting the quality of life.However,the current study on the seat is generally based on the needs of normal people for the principle,the special needs of patients with lumbar spondylosis comfort seat research is very few.In this regard,firstly,through the analysis of the characteristics of lumbar disease and the most common symptoms of lumbar disc herniation,pathogenic factors and rehabilitation factors,and the current situation of domestic and international design and Research on the seat and the related products of the patients with lumbar diseases were analyzed.Then through literature and field data,the differences of the physiological characteristics of lumbar intervertebral disc and lumbar muscle activity were analyzed.At the same time,based on the present situation of our country's office environment,using the user research method of questionnaire,observation,interview on patients with lumbar physiological and psychological characteristics,and the interaction between the seat and the dimension of time under the sitting posture and comfort related changes,analyzing the problems such as data mining research,special needs patients with lumbar to the seat,to find the suitable comfort seat impact factors of patients with lumbar disease and functional characteristics.In order to determine the size of the seat construction of human-machine function model,interactive simulation prototype in the formal or informal role play,the work efficiency and fatigue comfort comfort factors to carry out evaluation,finally to design scheme is verified and presented for lumbar disease patients comfort seat function characteristics model.In order to alleviate and reduce the pain of patients with lumbar disease,protect the waist,improve their quality of life,and guide more healthy life style,and put forward the design and the future research direction for the comfort of the seat of the demand differences of the patients with lumbar vertebra disease.
