Isihlalo ukuxazulula inkinga yokuhlala; Isihlalo se-ergonomic ukuxazulula inkinga yokuhlala phansi.
Kususelwa kwimiphumela ye-Lumbar Enterntertebral disc (L1-L5) I-Force Okutholakele:
Ukulala embhedeni, amandla emgogodleni we-lumbar yisikhathi esingu-0,25 sokuma okujwayelekile okumi, okuyisimo esivuseleleke kakhulu futhi esinethezekile somgogodla we-lumbar.
Ekuhambeni okujwayelekile kokuhlala, amandla emgogodleni we-lumbar yi-1.5 izikhathi eziyi-1.5 zokuma okujwayelekile ukuma, futhi i-pelvis ayithathi hlangothi ngalesi sikhathi.
Umsebenzi wokuzithandela, amandla omgogodla we-lumbar we-standard emile ejwayelekile engu-1.8 izikhathi eziyi-1.8, lapho uPelvis ekhula phambili.
Hlala phansi etafuleni, i-Lumbar Spine Force for the standard emi amahlathi izikhathi eziyi-2.7, ukulimala kakhulu kwi-lumbar spine attine state state.
I-angle yasemuva imvamisa phakathi kuka-90 ~ 135 °. Ngokwandisa i-angle phakathi komhlane kanye ne-tushion, i-pelvis ivunyelwe ukutshekela emuva. Ngaphezu kokuxhaswa phambili kwe-Lumbar Parlew eLumbar Spine, umgogodla ugcina i-curvature evamile eyenziwe ngamabutho ajwayelekile kuwo womabili amabutho. Ngale ndlela, amandla emgogodleni we-lumbar izikhathi eziyi-0,75 indawo yokuma, okungenzeka ukuthi ikhalule.
Ukuxhaswa kwasemuva naseLumbar kungumphefumulo wezihlalo ze-ergonomic. I-50% yenkinga yenduduzo etholakala kulokhu, amanye ama-35% asuka eCushion kanye ne-15% evela e-Armrest, ekhanda, izinyawo kanye nokunye okuhlangenwe nakho okuhleliwe.
Ungasikhetha kanjani isihlalo esifanele se-ergonomic?
U-Ergonomic Chay umkhiqizo owenziwe ngezifiso njengoba umuntu ngamunye enokuphakama kwakhe, isisindo kanye nengxenye yomzimba. Ngakho-ke, usayizi ofanelekile kuphela ongakhulisa umphumela we-ergonomics, njengezingubo nezicathulo.
Mayelana nokuphakama, kukhona izinketho ezilinganiselwe zabantu abanosayizi omncane (ngaphansi kuka-150 cm) noma usayizi omkhulu (ngenhla kwe-185 cm). Uma wehlulekile ukwenza ukukhetha okuhle, imilenze yakho ingahle isebenze emhlabathini, nekhanda ekhanda lakho nasentabeni yakho lingene.
Ngokuqondene nesisindo, abantu abanciphile (ngaphansi kwama-60 kg) abaphakamisi ukukhetha izihlalo ngokuxhaswa kanzima kwe-lumbar. Akunandaba ukuthi kulungiswa kanjani, okhalweni kuyamjaha futhi kungakhululeki. Abantu abanamafutha (ngaphezulu kwe-90 kg) abancomi ukukhetha izihlalo eziphakeme ze-elastic mesh. Ama-cushions kuzoba lula ukucwila, okwenza ukujikeleza kwegazi okumpofu emilenzeni nasekulinganisweni okulula emathangeni.
Abantu abanosizi okhanyisile, ubunzima bemisipha, ama-disc amabi, isihlalo ngokuxhaswa kwe-sacral noma ukuxhumeka okuhle kwe-back and cushion kuzonconywa kakhulu.
Ukugcina
Isihlalo se-ergonomic siyindilinga ezungezile, eguquguqukayo futhi eguqukayo yokusekelwa. Akunandaba noma kubiza kakhulu isihlalo se-ergonomic, akunakukugwema ngokuphelele ukulimala okulethwe ukuhlala phansi.
