Ubungakanani bovavanyo: Ukulungelelaniswa ngokufanelekileyo kwi-helmet kukhuselekile

Ubungakanani obufanelekileyo buyisiseko se-helmet ukunika ukhuseleko olufanelekileyo. Kuphela ngokufanelekileyo ngokufanelekileyo intloko inokubonelela ngokukhuseleka kokhuseleko kwimizuzu ebalulekileyo.

Okokuqala, kuyimfuneko ukulinganisa ngokuchanekileyo umjikelezo wentloko. Sebenzisa iteyiphu ethambileyo ukulinganisa indawo ebanzi yentloko (ngokuqhelekileyo isangqa entla kwamashiya neendlebe). Ngethuba lokulinganisa, i-tape ethambileyo kufuneka igcinwe i-horizontal kwaye idibene ngokusondeleyo nentloko, kodwa ingaqini kakhulu. Ngokuqhelekileyo, i-circumference yentloko yabantu abadala iphakathi kwe-54-62 centimeters, kwaye iimpawu ezahlukeneyo kunye neemodeli zee-helmets ziya kuba neetshathi zobukhulu obuhambelanayo. Khetha ubungakanani obufanelekileyo ngokusekelwe kwisangqa esilinganisiweyo sentloko kwaye uthelekise kunye netshathi yobungakanani.

Kukho nemithetho yokuzama izigcina-ntloko. Nxiba isigcina-ntloko ngokuthe tye entloko, uqinisekise ukuba umphetho wesigcina-ntloko umalunga nesentimitha e-1 ngaphezu kwamashiya, ungabhekeli phambili okanye ngasemva. I-tilt yangaphambili inokubangela ukuba isigcina-ntloko singaphumeleli ukukhusela ngokufanelekileyo ibunzi, ngelixa ukujikeleza ngasemva kunokuthintela umgca wokubona kunye nokusilela ukukhusela ukhuseleko lwendawo yangasemva yentloko. Lungisa iintambo zesigqoko, vula iintambo, ziqinise ngokukhawuleza de zikhululeke. Iintambo kufuneka zibekwe phantsi kweendlebe kwaye zifakwe ngokuqinileyo phantsi kwe-chin, zishiya i-gap yomnwe omnye. Kweli nqanaba, ngobunono hlunguza intloko ngasemva, ngaphambili, ngasekhohlo, nasekunene ukujonga ukuba isigcina-ntloko sizinzile. Phantsi kweemeko eziqhelekileyo, isigcina-ntloko akufuneki sibe nakuphi na ukushukuma okuphawulekayo okanye ukufuduswa. Ukuba i-helmet ishukuma, i-slip, okanye ibangela uxinzelelo entloko ngexesha lenkqubo yokugqoka isilingo, ibonisa ukuba ubungakanani abufanelekanga kwaye kufuneka bukhethwe kwakhona.
