Ukuphonononga iiHelmet eziPhezulu zesithuthuthu: Isikhokelo esiBanzi

Xa kuziwa ekukhweleni izithuthuthu, ukhuseleko lolona lubalulekileyo, kwaye ukukhetha isigcina-ntloko esifanelekileyo sisigqibo esibalulekileyo wonke umkhweli ajongene nawo. Izigcina-ntloko zesithuthuthu azikhuseli nje intloko yakho xa kukho ingozi kodwa zikwaphucula amava okukhwela ngokunciphisa ingxolo yomoya, ukukhusela ubuso bakho kububutyobo, kunye nokuqinisekisa ukuthuthuzeleka xa ukhwele ixesha elide. Esi sikhokelo siphonononga imiba ebalulekileyo yezigqoko zezithuthuthu eziphezulu, zijolise kwimigangatho yokhuseleko, izinto eziphathekayo, ukufaneleka kunye nokuthuthuzela, ukubonakala, kunye neempawu ezongezelelweyo ezibaluleke kakhulu kubagibeli.

Isiqulatho:
1. Imigangatho yokhuseleko kunye neziqinisekiso
2. Izinto eziphathekayo kunye nokwakhiwa
3. Fit kunye nentuthuzelo
4. Ukubonakala
5. Iinkcukacha ezongezelelweyo

Xa ukhetha i-helmet yesithuthuthu, into yokuqala kunye neyona nto ibalulekileyo kufuneka ibe yimigangatho yokhuseleko kunye neziqinisekiso. Izigcina-ntloko zivavanywa ngokuqatha ukuze zihlangabezane neziqinisekiso ezithile zokhuseleko, ezifana ne-DOT (iSebe lezoThutho) e-United States, i-ECE (iKomishoni yezoQoqosho yaseYurophu) eYurophu, kunye ne-Snell, engumgangatho wokuzithandela onika amanqanaba aphezulu okhuseleko. Ezi ziqinisekiso ziqinisekisa ukuba isigcina-ntloko sinokukhusela ngokwaneleyo intloko yomkhweli phezu kwempembelelo, ukuxhathisa ukungena, kunye nokuqinisekisa ukuba inkqubo yokugcina (i-chin strap) ihlala ibotshelelwe ngokukhuselekileyo.

Ukuqonda umahluko phakathi kwezi ziqinisekiso kunokunceda abakhweli benze ukhetho olunolwazi. Ngokomzekelo, imigangatho ye-ECE ibandakanya iimvavanyo zokuxhathisa i-abrasion kunye nentsimi yombono i-DOT engenziyo, ngelixa i-Snell ibandakanya iimvavanyo zempembelelo ezingqongqo. Nangona kunjalo, nasiphi na isigcina-ntloko esihlangabezana nale migangatho eyaziwayo sithathwa njengekhuselekile ekusetyenzisweni kwendlela.

Kukwabalulekile ukuqaphela ukuba izigcina-ntloko ziyilelwe ukufunxa impembelelo ngokutshabalalisa kancinane okanye ukuguqula i-liner ngexesha lengozi. Ngoko ke, isigcina-ntloko kufuneka sitshintshwe emva kwempembelelo enkulu, nokuba akukho monakalo obonakalayo.

Izinto eziphathekayo kunye nokwakhiwa kwe-helmet zidlala indima ebalulekileyo ekukhuseleni nasekuthuthuzeleni kwayo. Izigcina-ntloko zezithuthuthu ezikumgangatho ophezulu ziqhele ukwenziwa ngezinto ezidityanisiweyo ezifana ne-carbon fiber, i-fiberglass, okanye i-Kevlar, enika ibhalansi enkulu phakathi kobunzima kunye nokhuseleko. Ezi zixhobo ziyaziwa ngokukwazi ukufunxa kunye nokusabalalisa amandla empembelelo, ukunciphisa umngcipheko wokulimala.

Ukwakhiwa kwe-helmet kukwabandakanya igobolondo langaphandle kunye nomgca wangaphakathi. Iqokobhe langaphandle lenzelwe ukucinezela impembelelo, isasaza amandla kwindawo enkulu, ngelixa i-liner yangaphakathi, edla ngokwenziwa nge-polystyrene eyandisiweyo (EPS) foam, ifunxa umothuko. Olu lwakhiwo lunemigangatho emibini lubalulekile ekukhuseleni intloko yomkhweli kwimikhosi ethe ngqo nejikelezayo ngexesha lengozi.

Ngaphezu koko, ubunzima kunye ne-aerodynamics yesigcina-ntloko sikwaphenjelelwa zizinto zayo kunye nokwakhiwa. Izigcina-ntloko ezilula zinciphisa ukudinwa kwentamo kuhambo olude, ngelixa uyilo olulungiselelwe nge-aerodynamically lunokunciphisa ingxolo yomoya kwaye luphakamise ngesantya esiphezulu.

Ukufaneleka kwesigcina-ntloko kunye nokuthuthuzela kubalulekile ekuqinisekiseni ukusebenza kwaso ekukhuseleni umkhweli. Isigcina-ntloko kufuneka silungelelanise intloko kunye nobuso ngaphandle kokuqiniswa kakhulu, njengoko iindawo zoxinzelelo zingabangela ukungahambi kakuhle kwexesha. Kubalulekile ukuzama kwiisayizi ezahlukeneyo kunye neemilo ukuze ufumane ukulingana okufanelekileyo, njengoko iimilo zentloko zihluka kakhulu phakathi kwabantu.

Ukungena komoya ngokufanelekileyo yenye inkalo ebalulekileyo yokufaneleka kunye nokuthuthuzela. Izigcina-ntloko ezinomoya owaneleyo zigcina umkhweli epholile kwaye zithintela i-visor ekugqumeni, iphucula induduzo kunye nokubonakala. Jonga izigcina-ntloko ezineentshisi ezilungelelanisiweyo ezivumela ukuhamba komoya okulungiselelweyo ngokusekelwe kwiimeko zokukhwela kunye nokhetho lomntu.

Ukongezelela, i-padding yangaphakathi yesigcina-ntloko, ehlala ikhutshwa kwaye ihlanjwe, igalelo kwinduduzo kunye nococeko. Iilayini ezikumgangatho ophezulu ezenziwe ngezinto eziphefumlayo, ezithintela ukufuma zinokuphucula kakhulu amava okukhwela, ngakumbi ngexesha lohambo olude okanye kwimozulu eshushu.

Ukubonakala kuyinkalo ebalulekileyo yokhuseleko echaphazelekayo kuyilo lwesigqoko. I-visor okanye i-face shield kufuneka inikeze indawo ebanzi yokujonga ukuvumela abakhweli ukuba babone indlela kunye neendawo ezibangqongileyo ngokucacileyo. Khetha izigcina-ntloko ezine-anti-inkungu, i-anti-scratch, kunye nee-visor ezikhuselweyo ze-UV ukuze ugcine umbono ocacileyo kwiimeko ezahlukeneyo zokukhwela.

Ezinye izigcina-ntloko zikwabonisa ii-visor zelanga ezidityanisiweyo, eziphelisa imfuneko yeendondo zelanga kunye nokuvumela abakhweli ukuba balungelelanise ngokulula ukutshintsha iimeko zokukhanya. Ukongezelela, umbala wesigcina-ntloko kunye noyilo lunokuba nefuthe ekubonakaleni; imibala eqaqambileyo kunye nezinto ezikhanyayo zenza ukuba abakhweli babonakale ngakumbi kwabanye abasebenzisi bendlela, ukuphucula ukhuseleko.

Izigcina-ntloko zezithuthuthu zala maxesha ziza zixhotyiswe ngoluhlu lweempawu ezongezelelekileyo eziyilelwe ukuphucula ukhuseleko, intuthuzelo, kunye nokulula. Uqhagamshelo lweBluetooth luvumela abakhweli ukuba banxibelelane ngokulula nabanye abakhweli, ukufowuna, kunye nokumamela umculo okanye imiyalelo yokukhangela ngaphandle kokubeka esichengeni ukhuseleko.

Ezinye izinto ezintsha zibandakanya iinkqubo zokukhutshwa ngokukhawuleza, ezenza ukuba abaphenduli bokuqala bakhuphe ngokukhuselekileyo i-helmet ngaphandle kokubangela ukulimala okongeziweyo, kunye ne-MIPS (i-Multi-directional Impact Protection System), eyongeza uluhlu olongezelelweyo lokukhusela kwimikhosi ejikelezayo kwingozi.

Xa ukhetha i-helmet, qwalasela ukuba zeziphi iimpawu ezihambelana nesimbo sakho sokukhwela kunye nezinto ozikhethayo. Ngelixa iimpawu ezongezelelweyo zinokuphucula amava okukhwela, akufuneki zibeke esichengeni umsebenzi ophambili wesigcina-ntloko: ukhuseleko.

Ukukhetha isigcina-ntloko sesithuthuthu esifanelekileyo sisigqibo esibalulekileyo esichaphazela ukhuseleko kunye nolonwabo endleleni. Ngokuqonda ukubaluleka kwemigangatho yokhuseleko kunye neziqinisekiso, ukuqwalasela izinto kunye nokwakhiwa, ukuqinisekisa ukufaneleka kunye nokuthuthuzela okufanelekileyo, ukubeka phambili ukubonakala, kunye nokuvavanya iimpawu ezongezelelweyo, abakhweli banokwenza ukhetho olunolwazi oluphucula ukhuseleko lwabo kunye namava okukhwela. Khumbula, isigcina-ntloko lutyalo-mali kukhuseleko lwakho kunye nempilo entle endleleni.
