Phambi kwesihlalo ecaleni komgama othe nkqo emhlabeni ubizwa ngokuba ngukuphakama kwesihlalo, ukuphakama kwesihlalo yenye yezinto eziphambili ezichaphazela iqondo lokuhlala intuthuzelo, ukuphakama kwesihlalo esingenangqiqo kuya kuchaphazela ukuma kwabantu, ukudinwa esinqeni, ukuvelisa izifo ezinjalo. njengediski ye-lumbar ixesha elide phantsi.Inxalenye yoxinzelelo lomzimba isasazwa emilenzeni.Ukuba isihlalo siphezulu kakhulu kwaye imilenze imisiwe emhlabeni, imithwalo yegazi yethanga iya kuxinzelelwa kwaye ukujikeleza kwegazi kuya kuphazamiseka;Ukuba isihlalo siphantsi kakhulu, idolo elihlangeneyo liya kukhwela phezulu kwaye uxinzelelo lomzimba luya kugxininiswa kumzimba ophezulu.Kwaye ukuphakama kwesihlalo esifanelekileyo, ngokomgaqo we-ergonomic kufuneka kube: ukuphakama kwesihlalo = ithole + unyawo + ubukhulu besihlangu - indawo efanelekileyo, ikhefu yi-43-53 cm.
Umgama ukusuka kumda ongaphambili ukuya kumda ongasemva wesihlalo uba bubunzulu besihlalo.Ubunzulu besihlalo bunxulumene nokuba umva womzimba womntu unokudityaniswa ngasemva kwesitulo.Ukuba ubuso besihlalo bunzulu kakhulu, indawo yokuxhasa umva womntu iya kunqunyanyiswa, okubangela ukuba ithole lincinci, njl.;Ukuba ubuso besihlalo bunzulu kakhulu, icala elingaphambili lethanga liya kuxhoma, kwaye bonke ubunzima buphezu kwethole, ukudinwa komzimba kuya kukhawuleza.Ngokwezifundo ze-ergonomic, isithuba sobunzulu besihlalo yi-39.5-46cm.
Xa abasebenzi bekwindawo yokuhlala, ii-tubercles ezimbini ze-ischial phantsi kwe-pelvis yomntu zivame ukuba zithe tye.Ukuba uyilo lwe-Angle yendawo yokuhlala alunangqiqo kwaye lubonisa ubume bebhakethi, i-femur iya kujikeleza phezulu, kwaye imisipha ye-hip inokufumana uxinzelelo kwaye umzimba uya kuziva ungakhululekile.Ububanzi besihlalo bubekwe ngobungakanani benyonga yomntu kunye noluhlu olufanelekileyo lwentshukumo, ngoko ke uyilo lomphezulu wesihlalo kufuneka lube banzi kangangoko.Ngokutsho kobukhulu bomzimba womntu, ububanzi besihlalo buyi-46-50cm.
Uyilo lwe-armrest lunokunciphisa umthwalo wengalo, ukwenzela ukuba izihlunu zamalungu aphezulu ziphumle ngcono.Xa umzimba womntu uphakama okanye utshintsha indlela yokuma, unokuxhasa umzimba ukuze uncede umzimba ugcine ulungelelwano, kodwa ukuphakama kwe-armrest kufuneka kube kuyilo olufanelekileyo, i-armrest ephezulu kakhulu okanye ephantsi kakhulu iya kubangela ukudinwa kwengalo.Ngokophando lwe-ergonomic, ukuphakama kwe-armrest kuhambelana nomgama kwindawo yokuhlala, kwaye umgama olawulayo ngaphakathi kwe-19cm-25 cm unokuhlangabezana neemfuno zabasebenzi abaninzi.I-Engile yecala elingaphambili le-armrest kufuneka itshintshe kunye ne-Angle yokuhlala kunye ne-backrest Angle.
Umsebenzi oyintloko we-lumbar lean kukuxhasa isinqe, ukwenzela ukuba izihlunu ezinqeni zikwazi ukuphumla, kwaye umva womzimba womntu unokwenza uxhaso olusezantsi kunye nenkxaso yenqaku eliphezulu, ukwenzela ukuba umva womzimba womntu ufumane. ukuphumla okupheleleyo.Ngokutsho kwedatha ye-physiological human, ukuphakama okufanelekileyo kwesinqe yi-vertebra yesine neyesihlanu ye-lumbar, i-15-18cm ukusuka kwi-cushion, ngokuhambelana ne-curve ye-physiological human ukuqinisekisa ukukhululeka kokuhlala.
Ngoko ke, iisitulo ofisi efanelekileyokufuneka isekelwe kubukhulu be-anthropometric, ngokuhambelana ngokungqongqo noyilo lwe-ergonomic lwesihlalo.Nabasebenzi abayi kuziva bediniwe emzimbeni nasengqondweni kumsebenzi omninzi wexesha elide, ukuze kuncitshiswe izifo ezibangelwa kukungakhululeki kokuhlala, ukuze umsebenzi ugqitywe ngokukhawuleza nangempumelelo.
