Isixhobo esibonelela nge-buffer emotweni okanye kumqhubi ngexesha loxinzelelo lwempembelelo.
Kwiminyaka engamashumi amabini eyadlulayo, umphambili kunye ne-bumpers yemoto yenziwa ikakhulu ngezinto zentsimbi. Baye bafakwa kwisitampu kwi-teennel yentsimbi enobunzima obungaphezulu kwe-3mm. Umphezulu waphathwa nge-chrome kwaye ikhutshiwe okanye idlwengulwe kunye nomnyhali wexesha elide yesakhelo. Ngophuhliso lweshishini lemoto, i-bumper ye-bumper njengesixhobo esibalulekileyo sokhuseleko sikwindlela yokuphucula izinto ezintsha. Namhlanje i-carner yemoto yangaphambili nangasemva ukongeza ekugcineni umsebenzi wokukhusela oKwaba, kodwa nokwenza impiliso kunye nomanyano ngobume bomzimba, ukufuna ukukhanya kwayo. Ukuze kufezekiswe le njongo, umphambili kunye ne-bumpers yemoto yenziwa ngeplastiki, eyaziwa ngokuba yi-Bumpers.I-Bumper sisixhobo sokhuseleko esikufumanisayo kwaye sikhusela ngaphambili kunye nomqolo webhunga lemoto. Kwiminyaka engamashumi amabini eyadlulayo, umphambili kunye ne-bumpers yemoto yenziwa ikakhulu ngezinto zentsimbi. Zazisiwe kwi-U-Channel Stoel enobunzima obungaphezulu kwe-3mm. Umphezulu waphathwa nge-chrome kwaye ikhutshiwe okanye idyile kunye nesolo. Ngophuhliso lweshishini lemoto, i-bumper ye-bumper njengesixhobo esibalulekileyo sokhuseleko sikwindlela yokuphucula izinto ezintsha. Namhlanje i-carner yemoto yangaphambili nangasemva ukongeza ekugcineni umsebenzi wokukhusela oKwaba, kodwa nokwenza impiliso kunye nomanyano ngobume bomzimba, ukufuna ukukhanya kwayo. Ukufezekisa le njongo, umphambili kunye ne-bumpers yemoto yenziwa ngeplastiki, eyaziwa ngokuba zii-bumpers zeplastiki. I-Bumper yeplastiki iqulunqwe ngamacandelo amathathu, njengeplate yangaphandle, izinto ezibonakalayo kunye nomthi. Iplate yangaphandle kunye nezinto ze-buffer zenziwa ngeplastiki, kwaye i-beam yenziwa kwiphepha eliqengqelekayo eline-1.5 mm kwaye ifakwe isitampu kwi-roove ye-U-Groove egcwele i-u-roove ye-U-Groove; Iplate yangaphandle kunye nezinto ze-cushioing ziqhotyoshelwe kwi-Beam, eqhotyoshelwe kwisikrelemnqa sololiwe kwaye inokususwa nangaliphi na ixesha. Olu hlobo lweplastiki lusebenzisa iplasitiki, ngokusisiseko usebenzisa uluhlu lwePolterster kunye nothotho lwePolypropynene wezinto ezimbini, usebenzisa indlela yokubumba. Kwelinye ilizwe kukho uhlobo lweplastiki obizwa ngokuba yiPolycarbon Ester, indlela yokugcina inaliti, kodwa ineengenelo zokungasebenzi, kwaye ineenzuzo zokuhamba kwamandla, kunye nexabiso lokuthintela emotweni. I-Bumper yeplastiki inamandla, i-rigidity kunye nomhombiso, ukusuka kwimbono yokhuseleko, ukungqubana kwemoto kungadlala indima ye-buffer, khusela i-Bible Toub, idityaniswe ngokupheleleyo, ibe yinxalenye ebalulekileyo yembonakalo yemoto yokuhombisa.
