Kasupe wa wotchi amagwiritsidwa ntchito kulumikiza chikwama chachikulu cha mpweya (chomwe chili pa chiwongolero) ndi cholumikizira cha mpweya, chomwe kwenikweni ndi cholumikizira cha waya. Chifukwa chikwama chachikulu cha mpweya chiyenera kuzungulira ndi chiwongolero, (chingaganizidwe ngati cholumikizira cha waya chokhala ndi kutalika kwina, chozunguliridwa mozungulira shaft yoyendetsera chiwongolero, ndipo chingamasulidwe kapena kumangidwa munthawi yake chiwongolero chikazunguliridwa, komanso chili ndi malire, kuti chitsimikizire kuti cholumikizira cha waya sichingachotsedwe chiwongolero chikazunguliridwa kumanzere kapena kumanja mpaka kufa) kotero cholumikizira cha waya chiyenera kusiyidwa ndi malire, ndipo chowongolera chiyenera kuzunguliridwa kumbali imodzi popanda kuchotsedwa. Mfundo iyi ikufunika chisamaliro chapadera mukayiyika, yesetsani kuyisunga pakati.
Ntchito Pakagwa ngozi ya galimoto, dongosolo la airbag limagwira ntchito bwino kwambiri poteteza chitetezo cha oyendetsa ndi okwera.
Pakadali pano, makina a airbag nthawi zambiri amakhala makina a airbag imodzi yoyendetsera chiwongolero, kapena makina a airbag awiri. Galimoto yokhala ndi ma airbag awiri ndi makina oyendetsera lamba lachitetezo ikagundana, mosasamala kanthu za liwiro, ma airbag ndi ma pretensioner a lamba lachitetezo amachita nthawi imodzi, zomwe zimapangitsa kuti ma airbag awonongeke panthawi ya kugundana kwa liwiro lotsika komanso kukwera kwambiri kwa ndalama zokonzera.
Dongosolo la ma airbag awiri lochita zinthu ziwiri limatha kusankha lokha kugwiritsa ntchito chotenthetsera lamba lachitetezo chokha, kapena chotenthetsera lamba lachitetezo ndi ma airbag awiri kuti agwire ntchito nthawi imodzi malinga ndi liwiro ndi kuthamanga kwa galimotoyo galimoto ikagundana. Mwanjira imeneyi, pakagwa ngozi yothamanga pang'ono, dongosololi limatha kuteteza mokwanira okweramo pogwiritsa ntchito ma airbag okha, osawononga ma airbag. Ngati ngozi yachitika pa liwiro loposa 30km/h, ma airbag ndi ma airbag amagwira ntchito nthawi imodzi kuteteza chitetezo cha oyendetsa ndi okwera.
Chitetezo cha galimoto chimagawidwa m'magulu awiri: chitetezo chogwira ntchito ndi chitetezo chopanda ntchito. Chitetezo chogwira ntchito chimatanthauza kuthekera kwa galimoto kupewa ngozi, ndipo chitetezo chopanda ntchito chimatanthauza kuthekera kwa galimoto kuteteza anthu omwe ali mgalimoto pakagwa ngozi. Galimoto ikagwa ngozi, kuvulala kwa anthu omwe ali mgalimoto kumachitika nthawi yomweyo. Mwachitsanzo, pakagwa ngozi ya 50 km/h, zimatenga gawo limodzi mwa magawo khumi okha a sekondi. Pofuna kupewa kuvulala kwa anthu omwe ali mgalimoto nthawi yochepa chonchi, zida zotetezera ziyenera kuperekedwa. Pakadali pano, pali malamba achitetezo, chitetezo cha thupi chotsutsana ndi kugundana ndi mpweya (Supplemental Inflatable Restraint System, yotchedwa SRS) ndi zina zotero.
Popeza ngozi zambiri sizingapeweke, chitetezo chopanda ntchito nachonso n'chofunika kwambiri. Chifukwa cha kafukufuku wokhudza chitetezo chopanda ntchito, matumba a mpweya apangidwa mofulumira komanso otchuka chifukwa cha kugwiritsidwa ntchito kwawo mosavuta, zotsatira zake zodabwitsa komanso mtengo wake wotsika.
kuchita
Kuyesera ndi machitidwe atsimikizira kuti galimoto ikalandira dongosolo la airbag, kuchuluka kwa kuvulala kwa dalaivala ndi anthu omwe ali mgalimoto pangozi ya ngozi yakutsogolo kwa galimoto kumachepa kwambiri. Magalimoto ena samangokhala ndi airbag yakutsogolo, komanso airbags zam'mbali, zomwe zimathanso kudzaza airbags zam'mbali ngati galimoto yagundana mbali, kuti achepetse kuvulala pakagundana mbali. Chiwongolero cha galimoto yokhala ndi chipangizo cha airbag nthawi zambiri sichisiyana ndi chiwongolero wamba, koma chikagundana champhamvu kutsogolo kwa galimoto, airbag "imatuluka" mu chiwongolero nthawi yomweyo ndikuchiyika pakati pa chiwongolero ndi dalaivala. Pofuna kuletsa mutu ndi chifuwa cha dalaivala kugunda zinthu zolimba monga chiwongolero kapena dashboard, chipangizo chodabwitsachi chapulumutsa miyoyo yambiri kuyambira pomwe chinayambitsidwa. Bungwe lofufuza ku United States linafufuza ngozi zoposa 7,000 zamagalimoto ku United States kuyambira 1985 mpaka 1993 ndipo linapeza kuti chiwerengero cha imfa cha galimoto yokhala ndi chipangizo choteteza mpweya chinachepetsedwa ndi 30% kutsogolo kwa galimotoyo, ndipo chiwerengero cha imfa cha woyendetsa galimoto chinachepetsedwa ndi 30%. Ma sedan atsika ndi 14 peresenti.
