Mpando ndi kuthetsa vuto la kukhala; Mpando wa ergonomic ndi kuthetsa vuto lakukhala chete.
Kutengera zotsatira za mphamvu yachitatu ya lumbar intervertebral disc (L1-L5):
Kugona pabedi, mphamvu pa lumbar msana ndi 0,25 nthawi ya muyezo kuyimirira kaimidwe, amene ali kwambiri omasuka ndi omasuka mkhalidwe wa lumbar msana.
Pakukhazikika kokhazikika, mphamvu ya m'chiuno mwa msana ndi nthawi 1.5 kuposa momwe imayimira, ndipo chiuno sichilowererapo panthawiyi.
Ntchito yodzifunira, mphamvu ya msana ya lumbar yokhazikika nthawi 1.8, pamene chiuno chimapendekera kutsogolo.
Mutu pansi pa tebulo, lumbar msana mphamvu kwa muyezo kuyimirira lakhalira nthawi 2.7, ndi kuvulala kwambiri kwa lumbar msana atakhala lakhalira.
Mbali ya backrest nthawi zambiri imakhala pakati pa 90 ~ 135 °. Powonjezera ngodya pakati pa msana ndi khushoni, pelvis imaloledwa kubwerera kumbuyo. Kuphatikiza pa kuthandizira kutsogolo kwa lumbar pilo kupita ku lumbar spine, msanawo umakhala ndi mawonekedwe ozungulira a S ndi mphamvu zonse ziwiri. Mwanjira imeneyi, mphamvu ya msana wam'chiuno ndi 0.75 nthawi yoyimirira, zomwe sizingakhale zotopa.
Backrest ndi lumbar thandizo ndi moyo wa mipando ergonomic. 50% ya vuto lachitonthozo limachokera ku izi, ena 35% kuchokera pamtsamiro ndi 15% kuchokera ku armrest, headrest, footrest ndi zina zomwe zimakhala.
Kodi mungasankhe bwanji mpando wa ergonomic?
Mpando wa ergonomic ndi chinthu chamunthu payekhapayekha popeza munthu aliyense ali ndi kutalika kwake, kulemera kwake ndi gawo lake la thupi. Chifukwa chake, kukula koyenera kokhako kumatha kukulitsa zotsatira za ergonomics, monga zovala ndi nsapato.
Pankhani ya kutalika, pali zosankha zochepa kwa anthu omwe ali ndi kukula kochepa (pansi pa 150 cm) kapena kukula kwakukulu (pamwamba pa 185 cm). Ngati mwalephera kusankha bwino, miyendo yanu ingakhale yovuta kuponda pansi, mutu wanu uli pamutu ndi pakhosi.
Ponena za kulemera, anthu owonda (ochepera 60 kg) samasankha kusankha mipando ndi chithandizo cholimba cha lumbar. Ziribe kanthu momwe angasinthire, chiuno chikutsamwitsidwa komanso chosamasuka. Anthu onenepa kwambiri (oposa 90 kg) samalimbikitsa kusankha mipando yapamwamba yotanuka mauna. Ma cushions adzakhala osavuta kumira, zomwe zimapangitsa kuti magazi aziyenda bwino m'miyendo komanso dzanzi mosavuta m'ntchafu.
Anthu omwe ali ndi vuto la m'chiuno, kupsyinjika kwa minofu, ma disks a herniated, mpando wokhala ndi chithandizo cha sacral kapena kumbuyo kwabwino ndi kulumikizana kwa khushoni kungalimbikitse kwambiri.
Mapeto
Mpando wa ergonomic ndi njira yothandizira yozungulira, yosinthika komanso yosinthika. Ziribe kanthu kuti mpando wa ergonomic wokwera mtengo bwanji, sungathe kupeŵa kuvulaza komwe kumabwera chifukwa chokhala chete.
