1. Ukuhlala nokusebenza ixesha elide.
2. Uziva rhoqo iintlungu zomlomo wesibeleko kunye ne-lumbar.
3. Soloko uziva ungakhululekanga kwaye ungekho ngokwemvelo.
Ukuba ubetha enye yale ngongoma, kucetyiswa ukuba utshintshe ngokukhawuleza kwisitulo se-ergonomic.Ukulungelelaniswa okutyebileyo kwesitulo se-ergonomic kukuvumela ukuba ugcine ngokukhululekileyo indawo yokuhlala esempilweni.Ukuxhaswa kwe-lumbar spine, isinqe, kunye namagxa, kunye nokuxhaswa kweengalo kunokunciphisa kakhulu umthwalo kwi-lumbar spine kunye neengalo.Ukongeza kokuhlala ngokukhululeka, kunokunciphisa izifo ze-lumbar spine ezibangelwa ukuhlala ixesha elide.
Umgaqo wesitulo se-ergonomic
Okokuqala, umzimba womntu awukhelwanga ukuba uhlale ixesha elide.Njengoko kunokubonwa kulo mzobo ungasentla, ukusuka kwindawo yokuma ukuya kwindawo yokuhlala, amathambo e-disc athambekele phambili, ukuthambekela kwe-sacral kuba kuncinci, kwaye i-lumbar spine curve iba flat.I-angle yokuma enempilo ye-lumbar spine curve yi-20 ° -45 ° ngelixa ukuhlala ngaphandle kwenkxaso ye-lumbar kunciphisa i-angle ye-curve ngama-50%.
Olu tshintsho kwi-angle ye-lumbar curve luya kwandisa uxinzelelo lwangaphakathi lwe-disc ye-lumbar intervertebral disc ngaphezu kwe-40%, kwaye iya kukhokelela ekukhutshweni kwemisipha, okubangelwa intlungu ye-muscle, intlungu emva, kunye nezinye izinto.
Omnye wemisebenzi ebalulekileyo yesihlalo se-ergonomic kukuxhasa i-lordosis ye-lumbar vertebrae yesithathu kunye neyesine ngokusebenzisa umcamelo we-lumbar (inkxaso ye-lumbar) ukunciphisa uxinzelelo kwi-disc intervertebral disc, ngaloo ndlela ukunciphisa intlungu ephantsi.Okwesibini, umva wesitulo ubuyele umva malunga ne-100 °, enokwenza i-angle phakathi kwe-trunk kunye namathanga amakhulu kune-90 °, ekwanceda ukunciphisa uxinzelelo kumqolo.
Ukongeza, imisebenzi ehlengahlengiswayo yee-armrests, ukuphakama kwesitulo, ubunzulu besihlalo, i-backrest, njl. njl. zenza isitulo esipheleleyo se-ergonomic.
Shwankathela umgaqo wesitulo se-ergonomic kwisivakalisi esinye, ngokusebenzisa inkxaso ye-lumbar kunye neminye imisebenzi ehlengahlengiswayo, ukunciphisa uxinzelelo kwi-lumbar spine, kwaye unikeze indawo yokuhlala ekhululekile kunye nechanekileyo.
