I-Bumper sisixhobo sokhuseleko esifumana kwaye siyithobe ifuthe langaphandle kwaye likhusela ngaphambili kunye nemvelaphi yomzimba wemoto. Kwiminyaka engamashumi amabini eyadlulayo, umphambili kunye ne-bumpers yemoto yenziwa ikakhulu ngezinto zentsimbi. Baye bafakwa isitampu kwi-teen yetayini ye-U-Witnel enobunzima obungaphezulu kwe-3 mm, kwaye umphezulu waphathwa ngeChromium. Baye bakhutshelwa okanye badlwengulwe kunye nomdiliya wexesha elide yesakhelo, kwaye kukho umsantsa omkhulu ngomzimba, ngokungathi yinxalenye eqhotyoshelweyo. Ngophuhliso lweshishini lemoto, i-outur ye-automonjile 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: iplate yangaphandle, izinto ezibonakalayo kunye nomthi. Iplate yangaphandle kunye nezinto ze-buffer zenziwa ngeplastiki, kwaye i-beam yenziwa kwiphepha eliqengqelekayo elinobunzima obuyi-1.5 mm kwaye yenziwa kwi-roove ye-U-Groove ye-U-Groove; Iplate yangaphandle kunye nezinto ze-cushioing ziqhotyoshelwe kwi-Beam, eziqhotyoshelwe kwisikrelemnqa sololiwe kwaye zinokususwa nangaliphi na ixesha. Olu hlazo lweplastiki lusebenzisa iplasitiki, ngokusisiseko usebenzisa iintlobo ezimbini zezinto, i-polyester kunye nePolypropylene, usebenzisa indlela yokubumba. Kukho nohlobo lweplastiki ebizwa ngokuba yi-Polycarbon Estersbon Ester, ukungena kwi-Alfding ye-Ablsing, kodwa kuye kwanenzuzo ye-welding, kwaye inesixa esingakumbi emotweni. I-Bumper yeplastiki inamandla, i-rigidity kunye nomhlobiso, ukusuka kwimbono yokhuseleko, ingozi yemoto inokuthi idlale indima ye-buffer, inokuthi idityaniswe nomzimba kwisiqwengana, iyodwa, siyinxalenye ebalulekileyo yembonakalo yemoto yokuhombisa.
