Ngaphambi kwesihlalo eduze kwebanga eliqondile ukuya phansi kubizwa ngokuthi ukuphakama kwesihlalo, ukuphakama kwesihlalo kungenye yezinto eziyinhloko ezithinta izinga lokunethezeka kokuhlala, ukuphakama kwesihlalo okungenangqondo kuzothinta indlela abantu abahlezi ngayo, ukukhathala okhalweni, ukukhiqiza izifo ezinjalo. njenge-lumbar disc isikhathi eside phansi.Ingxenye yokucindezeleka komzimba isakazwa emilenzeni.Uma isihlalo siphakeme kakhulu futhi imilenze imisiwe phansi, imithwalo yegazi yethanga izocindezelwa futhi ukujikeleza kwegazi kuzothinteka;Uma isihlalo siphansi kakhulu, idolo elihlangene lizokhuphukela phezulu futhi ukucindezela komzimba kuzogxila emzimbeni ongaphezulu.Futhi ukuphakama kwesihlalo esinengqondo, ngokusho kwesimiso se-ergonomic kufanele kube: ukuphakama kwesihlalo = ithole + unyawo + ukushuba kwesicathulo - isikhala esifanele, isikhawu singama-43-53 cm.
Ibanga ukusuka onqenqemeni olungaphambili ukuya onqenqemeni olungemuva lwesihlalo liba ukujula kwesihlalo.Ukujula kwesihlalo kuhlobene nokuthi ingemuva lomzimba womuntu lingaxhunywa ngemuva kwesihlalo.Uma ubuso besihlalo bujule kakhulu, iphuzu lokusekela lomhlane womuntu lizomiswa, okubangela ukuba ndikindiki kwethole, njll.;Uma ubuso besihlalo bungashoni kakhulu, uhlangothi olungaphambili lwethanga luzolenga, futhi sonke isisindo sisetholeni, ukukhathala komzimba kuzosheshisa.Ngokwezifundo ze-ergonomic, isikhawu sokujula kwesihlalo singama-39.5-46cm.
Lapho abasebenzi behlezi, ama-tubercle amabili e-ischial ngaphansi kwe-pelvis yomuntu avame ukuba avundlile.Uma i-Angle design yendawo yokuhlala ingenangqondo futhi inikeza isimo sebhakede, i-femur izojikeleza phezulu, futhi imisipha ye-hip ingathola ingcindezi futhi umzimba uzozizwa ungakhululekile.Ububanzi besihlalo busethwe ubukhulu benyonga yomuntu kanye nohlu olufanele lokunyakaza, ngakho ukwakheka kwendawo yokuhlala kufanele kube banzi ngangokunokwenzeka.Ngokusho kobukhulu bomzimba womuntu obuhlukene, ububanzi besihlalo buyi-46-50cm.
Ukwakhiwa kwe-armrest kunganciphisa umthwalo wengalo, ukuze imisipha yamalungu angaphezulu iphumule kangcono.Lapho umzimba womuntu usukuma noma ushintsha ukuma, ungakwazi ukusekela umzimba ukuze usize umzimba ugcine ukulinganisela, kodwa ukuphakama kwe-armrest kufanele kube ngendlela eklanywe kahle, indawo yokubeka ingalo ephakeme kakhulu noma ephansi kakhulu izobangela ukukhathala kwengalo.Ngokocwaningo lwe-ergonomic, ukuphakama kwe-armrest kuhlobene nebanga lendawo yokuhlala, futhi ibanga elilawulwayo phakathi kuka-19cm-25 cm lingahlangabezana nezidingo zabasebenzi abaningi.I-engeli yohlangothi olungaphambili lwe-armrest kufanele futhi ishintshe nge-Engeli yesihlalo kanye ne-backrest Angle.
Umsebenzi oyinhloko we-lumbar lean ukusekela okhalweni, ukuze imisipha okhalweni ikhululeke, futhi ingemuva lomzimba womuntu lingenza ukusekelwa kwamaphuzu aphansi kanye nokwesekwa kwamaphuzu aphezulu, ukuze ingemuva lomzimba womuntu likwazi ukuthola. ukuphumula okuphelele.Ngokusho kwedatha ye-physiological yomuntu, ukuphakama okulungile kwesinqe yi-vertebra yesine neyesihlanu ye-lumbar, i-15-18cm ukusuka ku-cushion, ngokuhambisana nejika le-physiological yomuntu ukuqinisekisa ukunethezeka kokuhlala.
Ngakho-ke, i-isihlalo esihle sehhovisikufanele kusekelwe kusayizi we-anthropometric, ngokuhambisana ngokuqinile nomklamo we-ergonomic wesihlalo.Ngisho nabasebenzi ngeke bazizwe bekhathele ngokomzimba nangokwengqondo emsebenzini omningi wesikhathi eside, ukuze kuncishiswe izifo ezibangelwa ukungahambi kahle kokuhlala, ukuze umsebenzi uqedwe ngokushesha nangempumelelo.
