Isitulo kukusombulula ingxaki yokuhlala; Isitulo se-Ergonomic kukusombulula ingxaki yokuhlala.
Ngokusekelwe kwiziphumo ze-disc ye-lumbar intervertebral disc yesithathu (L1-L5) iziphumo zamandla:
Ukulala ebhedini, amandla kwi-lumbar spine yi-0.25 ixesha lokuma okusemgangathweni okusemgangathweni, eyona nto ikhululekile kwaye ikhululekile kwi-lumbar spine.
Kwi-standard standard, i-force kwi-lumbar spine yi-1.5 amaxesha e-standard standard, kwaye i-pelvis ayithathi hlangothi ngeli xesha.
Umsebenzi wokuzithandela, i-lumbar spine force ye-standard stand posture 1.8 amaxesha, xa i-pelvis iqhubela phambili.
Intloko phantsi kwetafile, i-lumbar spine force ye-standard stand stand 2.7 amaxesha, yiyona nto yokulimala kwi-lumbar spine sitting posture.
I-angle ye-backrest ngokubanzi iphakathi kwe-90 ~ 135 °. Ngokunyusa i-angle phakathi komva kunye ne-cushion, i-pelvis ivumelekile ukuba ibuyele ngasemva. Ukongeza kwinkxaso yangaphambili ye-lumbar pillow ukuya kwi-lumbar spine, umqolo ugcina i-curvature ye-S eqhelekileyo kunye nemikhosi yomibini. Ngale ndlela, amandla kwi-lumbar spine ngama-0.75 amaxesha okuma, okungenakwenzeka ukuba adinwe.
Ukuxhaswa kwe-backrest kunye ne-lumbar ngumphefumlo wezihlalo ze-ergonomic. I-50% yengxaki yokuthuthuzela ivela kule nto, i-35% eseleyo kwi-cushion kunye ne-15% kwi-armrest, i-headrest, i-footrest kunye namanye amava okuhlala.
Indlela yokukhetha isitulo esifanelekileyo se-ergonomic?
Isitulo se-Ergonomic yimveliso eyenziwe ngumntu ngakumbi kuba umntu ngamnye unobude bakhe, ubunzima kunye nomlinganiselo womzimba. Ke ngoko, ubukhulu obufanelekileyo kuphela obunokwandisa impembelelo ye-ergonomics, njengempahla kunye nezihlangu.
Ngokumalunga nokuphakama, kukho iinketho ezilinganiselweyo kubantu abanobukhulu obuncinci (ngaphantsi kwe-150 cm) okanye ubukhulu obukhulu (ngaphezulu kwe-185 cm). Ukuba awuphumelelanga ukwenza olona khetho lulungileyo, imilenze yakho inokuba nzima ukunyathela emhlabeni, ibe nentloko entloko nasentanyeni ibambekile.
Ngokuphathelele ubunzima, abantu abancinci (ngaphantsi kwe-60 kg) abacebisi ukukhetha izihlalo ezinobunzima be-lumbar inkxaso. Kungakhathaliseki ukuba ilungiswa njani, isinqe siyakrwitshwa kwaye asikhululeki. Abantu abatyebileyo (ngaphezulu kwe-90 kg) abacebisi ukukhetha izitulo eziphezulu ze-elastic mesh. I-Cushions iya kuba lula ukucwina, kubangela ukungahambi kakuhle kwegazi emilenzeni kunye nokulula okulula emathangeni.
Abantu abanokwenzakala esinqeni, ukuxinezeleka kwemisipha, iidiski ze-herniated, isitulo esinenkxaso ye-sacral okanye umqolo olungileyo kunye nokunxibelelana komqamelo kuya kucetyiswa kakhulu.
Ukuqukumbela
Isitulo se-ergonomic yinkqubo yenkxaso ejikelezayo, eguquguqukayo kwaye ehlengahlengiswayo. Kungakhathaliseki ukuba sibiza kangakanani isitulo se-ergonomic, asikwazi ukuphepha ngokupheleleyo umonakalo obangelwa ukuhlala.
