Izihlalo zasehhovisizidlala indima ebalulekile ekuphileni kwethu kwansuku zonke, ikakhulukazi kulabo abachitha amahora behlezi edeskini.Isihlalo esilungile singaba nomthelela omkhulu ekunethezekeni kwethu, ukukhiqiza, kanye nempilo yonke.Yilapho izihlalo zehhovisi le-ergonomic zingena khona.Izihlalo ze-ergonomic zakhiwe kucatshangelwa isayensi futhi zenzelwe ukunikeza ukwesekwa okuphezulu nokukhuthaza ukuma okulungile.Kulesi sihloko, sizobheka kabanzi isayensi ngemuva kwezihlalo zehhovisi le-ergonomic kanye nezinzuzo zazo.
Esinye sezici eziyinhloko zesihlalo se-ergonomic ukulungiswa kwayo.Lezi zihlalo zivame ukuza nobude besihlalo obulungisekayo, izindawo zokuhlala ezingalweni, kanye nokusekelwa kwe-lumbar.Ikhono lokwenza lezi zingxenye ngokwezifiso livumela abantu ukuthi bafinyelele isimo esihle sokuhlala ngokususelwa ekumeni kwabo okuhlukile nobukhulu.Isibonelo, ukulungisa ubude besihlalo sakho kuqinisekisa ukuthi izinyawo zakho ziphansi phansi futhi kugcina ukujikeleza kwegazi ngendlela efanele.Ukuphakama kwama-armrests kusekela amahlombe nezingalo ezikhululekile, kunciphisa ukucindezeleka entanyeni nasemahlombe.Ukusekelwa kwe-Lumbar kusiza ukugcina ukugoba kwemvelo komgogodla ophansi, ukuvimbela ukuhlehla nokukhuthaza ukuma okuhle.
Ukwesekwa okufanele kwe-lumbar kubaluleke kakhulu kusihlalo se-ergonomic.Indawo ye-lumbar yomgogodla, etholakala emhlane ophansi, iyakwazi ukukhahlazeka futhi ingakhululeki, ikakhulukazi uma ihlezi isikhathi eside.Izihlalo ze-ergonomic zixazulula le nkinga ngokuhlanganisa izici zokusekela i-lumbar.Lokhu kusekelwa kuncike ejikeni lemvelo lomgogodla, linikeza ukwesekwa okudingeka kakhulu endaweni ephansi yomgogodla.Ngokusekela i-curvature yemvelo, ukwesekwa kwe-lumbar kunciphisa ukucindezela kuma-discs nemisipha, ukunciphisa ubuhlungu obuphansi emuva nokuthuthukisa induduzo.
Ukwengeza, izihlalo ze-ergonomic zakhiwe kucatshangwa nge-biomechanics.I-Biomechanics iwucwaningo lokunyakaza komzimba nokuthi amandla angaphandle, njengokuhlala isikhathi eside, awuthinta kanjani umzimba.Izihlalo ze-ergonomic zenzelwe ukuthwala ukunyakaza kwemvelo komzimba futhi zinikeze ukwesekwa okwanele phakathi nalokhu kunyakaza.Iphoyinti le-pivot lesitulo se-ergonomic litholakala ezinqulwini, okuvumela umsebenzisi ukuthi anyakaze kalula futhi ehlise ingcindezi emhlane nasentanyeni.Izihlalo ngokwazo zivame ukuba nemiphetho yempophoma enciphisa ingcindezi emathangeni futhi ithuthukise ukugeleza kwegazi emilenzeni.
Kunezinzuzo eziningi zokusebenzisa i-ergonomicisihlalo sehhovisi.Okokuqala, lezi zihlalo zisiza ukunciphisa ingozi yokuphazamiseka kwe-musculoskeletal.Ukuhlala isikhathi eside esihlalweni esintula ukusekelwa okufanele kungabangela ubuhlungu emuva, ubuhlungu bentamo, nokunye ukungakhululeki.Izihlalo ze-ergonomic zinciphisa lezi zingozi ngokuthuthukisa isimo sokuhlala esingcono futhi zisekele ukuqondana kwemvelo komzimba.
Ukwengeza, izihlalo ze-ergonomic zingandisa umkhiqizo.Lapho abantu bekhululekile futhi bengenabuhlungu, bangakwazi ukuhlala begxilile futhi bematasa emsebenzini isikhathi eside.Izici ezilungisekayo zezihlalo ze-ergonomic zivumela abasebenzisi ukuthi bathole indawo enhle yokuhlala, okusiza ukukhulisa ukugxilisa ingqondo nokukhiqiza.Ukwengeza, ukuma okuhle kokuhlala kuthuthukisa ukujikeleza kwegazi, kuqinisekisa ukuthi izakhi ezibalulekile kanye ne-oksijeni zifinyelela ebuchosheni, kuthuthukise ukusebenza kwengqondo.
Kafushane, isayensi engemuva kwezihlalo zamahhovisi e-ergonomic izungeza ekunikezeni ukwesekwa okufanele, ukukhuthaza ukuma okufanele, nokuzivumelanisa nokunyakaza kwemvelo komzimba.Lezi zihlalo ziklanywe ngokuguquguquka kanye nokuqonda kwe-biomechanics engqondweni.Ukutshala imali ku-ergonomicisihlalo sehhovisiinganikeza izinzuzo ezingenakubalwa, okuhlanganisa ukunethezeka okuthuthukisiwe, ingozi encishisiwe yokuphazamiseka kwemisipha, ukukhiqiza okukhulayo kanye nempilo yonke ethuthukisiwe.Ngakho-ke ngesikhathi esilandelayo lapho ucabanga ukuthenga isihlalo sasehhovisi, khumbula isayensi engemuva kwaso bese ukhetha inketho ye-ergonomic yendawo enempilo, enethezekile yokusebenza.
