Pamberi pechigaro pamwe nechekureba kusvika pasi kunonzi kukwirira kwechigaro, kureba kwechigaro ndicho chimwe chezvinhu zvikuru zvinokanganisa dhigirii rekugara kunyaradzwa, kureba kwechigaro kusinganzwisisike kuchakanganisa kugara kwevanhu, kukanda kuneta muchiuno, kuburitsa zvirwere zvakadaro. sezvo lumbar disc nguva refu pasi.Chikamu chekumanikidzwa kwemuviri chinogoverwa pamakumbo.Kana chigaro chacho chakanyanya kukwirira uye makumbo akarembera kubva pasi, tsinga dzeropa dzechidya dzichamanikidzwa uye kutenderera kweropa kuchakanganiswa;Kana chigaro chakanyanya kuderera, mabvi akabatanidzwa anokwira kumusoro uye kumanikidza kwemuviri kuchaiswa pamusoro pemuviri wepamusoro.Uye kukwirira kwechigaro kunonzwisisika, maererano ne ergonomic musimboti kunofanira kuva: kureba kwechigaro = mhuru + tsoka + shangu ukobvu - nzvimbo yakakodzera, nguva yacho 43-53 cm.
Nhambwe kubva kumucheto wepamberi kusvika kumashure kwechigaro inova kudzika kwechigaro.Kudzika kwechigaro kune chekuita nekuti kumashure kwemuviri wemunhu kunogona kusungirirwa kumashure kwechigaro.Kana chiso chechigaro chakanyanya kudzika, nzvimbo yekutsigira yemusana wemunhu ichamiswa, zvichiita kuti chiveve chemhuru, nezvimwewo;Kana chiso chechigaro chakanyanya kudzika, rutivi rwemberi rwehudyu rucharembera, uye uremu hwose huri pamhuru, kuneta kwemuviri kuchawedzerwa.Zvinoenderana nezvidzidzo zveergonomic, kudzika kwechigaro kunosvika 39.5-46cm.
Kana mudonzvo uri munzvimbo yekugara, maviri ischial tubercles pasi pe pelvis yemunhu anowanzoita akachinjika.Kana iyo Angle dhizaini yechigaro chechigaro isinganzwisisike uye inopa chimiro chebhaketi, iyo femur inotenderera ichikwira kumusoro, uye mamhasuru ehudyu anogona kuwana kudzvanywa uye muviri unonzwa kusagadzikana.Hupamhi hwechigaro hunotarwa nehukuru hwehudyu yemunhu pamwe nemhando yakakodzera yekufamba, saka dhizaini yepamusoro yechigaro inofanira kunge yakafara sezvinobvira.Zvinoenderana nehukuru hwemuviri wemunhu, hupamhi hwechigaro ndeye 46-50cm.
Dhizaini yearmrest inogona kuderedza mutoro weruoko, kuitira kuti mamhasuru epamusoro emakumbo anogona kuzorora zviri nani.Kana muviri wemunhu wasimuka kana kushandura chimiro, unogona kutsigira muviri kuti ubatsire muviri kuchengetedza chiyero, asi kureba kwechigadziko chemaoko kunofanirwa kunge kuri mukugadzirwa kwakaringana, iyo armrest iyo yakakwira zvakanyanya kana yakaderera inokonzeresa kuneta kweruoko.Zvinoenderana neiyo ergonomic tsvagiridzo, kureba kwearmrest kwakabatana nekureba kwechigaro chepamusoro, uye kureba kwekudzora mukati me19cm-25 cm kunogona kuzadzisa zvinodiwa nevashandi vazhinji.Iyo Angle yedivi remberi re armrest inofanirawo kuchinja nechigaro Angle uye backrest Angle.
Basa guru re lumbar lean ndere kutsigira chiuno, kuitira kuti mhasuru dzechiuno dzisununguke, uye musana wemuviri wemunhu unogona kuumba tsigiro yepasi uye kutsigira kwepamusoro, kuitira kuti shure kwemuviri wemunhu uwane. kuzorora kwakakwana.Zvinoenderana nedata rehupenyu hwevanhu, kureba kwechiuno ndeyechina uye yechishanu lumbar vertebra, 15-18cm kubva kucushion, zvinoenderana nemunhu physiological curve kuve nechokwadi chekunyaradza kwekugara.
Naizvozvo, theyakanaka hofisi chairinofanira kunge yakavakirwa pahukuru hweanthropometric, zvakanyatsoenderana neiyo ergonomic dhizaini yechigaro.Kunyange vashandi havazonzwi vakaneta mumuviri uye mupfungwa mubasa rakawanda renguva refu, kuitira kuti vaderedze zvirwere zvinokonzerwa nekusagadzikana kwekugara, kuitira kuti basa rigone kupedzwa nokukurumidza uye zvinobudirira.
