1. Ukuhlala nokusebenza isikhathi eside.
2. Ngokuvamile ukuzwa ubuhlungu bomlomo wesibeletho kanye ne-lumbar.
3. Ngaso sonke isikhathi uzizwa ungakhululekile futhi ungeyona eyemvelo.
Uma ushaya elinye lala maphuzu, kunconywa ukuthi ushintshe ngokushesha esihlalweni se-ergonomic.Ukulungiswa okucebile kwesitulo se-ergonomic kukuvumela ukuthi ugcine ngokunethezeka ukuhleleka kokuhlala okunempilo.Ukusekelwa kwe-lumbar spine, ukhalo, namahlombe, kanye nokusekelwa kwezingalo kunganciphisa kakhulu umthwalo ku-lumbar spine nezingalo.Ngaphezu kokuhlala ngokunethezeka, kunganciphisa nezifo ze-lumbar spine ezibangelwa ukuhlala isikhathi eside.
Umgomo wesihlalo se-ergonomic
Okokuqala, umzimba womuntu awukhelwanga ukuhlala isikhathi eside.Njengoba kungabonakala kumfanekiso ongenhla, kusukela endaweni yokuma kuya endaweni yokuhlala, amathambo e-disc athambekele phambili, ukuthambekela kwe-sacral kuba kuncane, futhi ijika le-lumbar spine liba flat.I-engeli ye-lumbar spine curve emile enempilo ingu-20°-45° kuyilapho ukuhlala ngaphandle kokusekelwa kwe-lumbar kunciphisa i-engeli yejika ngo-50%.
Lolu shintsho ku-angle ye-lumbar curve luzokwandisa ukucindezela kwangaphakathi kwe-disc ye-lumbar intervertebral yesithathu ngaphezu kwe-40%, futhi kuzoholela ekuhlakazeni kwemisipha, okuholela ebuhlungu bemisipha, ubuhlungu be-back back, nezinye izenzakalo.
Omunye wemisebenzi ebalulekile yesihlalo se-ergonomic ukusekela i-lordosis ye-vertebrae yesithathu neyesine ngokusebenzisa umcamelo we-lumbar (ukusekelwa kwe-lumbar) ukunciphisa ukucindezela ku-disc intervertebral disc, ngaleyo ndlela kunciphise ubuhlungu obuphansi emuva.Okwesibili, ingemuva lesihlalo litshekele emuva cishe ku-100 °, okungenza i-engeli phakathi kwe-trunk namathanga ibe mkhulu kuno-90 °, okusiza nokunciphisa ukucindezela emhlane.
Ngaphezu kwalokho, imisebenzi elungisekayo yama-armrest, ukuphakama kwesihlalo, ukujula kwesihlalo, i-backrest, njll. yakha isihlalo esiphelele se-ergonomic.
Fingqa isimiso sesihlalo se-ergonomic emshweni owodwa, ngokusebenzisa ukusekelwa kwe-lumbar kanye neminye imisebenzi eguquguqukayo, unciphise ukucindezela kumgogodla we-lumbar, futhi unikeze ukuma okunethezekile nokulungile kokuhlala.
