Idivayisi enikeza imoto noma umshayeli isivikelo ngesikhathi sokucindezeleka komthelela.
Eminyakeni engamashumi amabili edlule, amabhampa angaphambili nangemuva ezimoto ayenziwe kakhulu ngezinto zensimbi. Anyatheliswa ensimbini yesiteshi enobunjwa obungu-U enobukhulu obungaphezu kuka-3mm. Ubuso baphathwa nge-chrome futhi baphonswa noma bahlanganiswa kanye nogongolo olude lohlaka. Ngokuthuthuka kwemboni yezimoto, i-bumper yemoto njengedivayisi yokuphepha ebalulekile nayo isendleleni yokusungula izinto ezintsha. Amabhampa angaphambili nangemuva ezimoto zanamuhla ngaphezu kokugcina umsebenzi wokuvikela wokuqala, kodwa futhi nokuphishekela ukuvumelana nobunye nesimo somzimba, ukuphishekela ukukhanya kwawo. Ukuze kufezwe le njongo, amabhampa angaphambili nangemuva ezimoto enziwe ngepulasitiki, aziwa ngokuthi amabhampa epulasitiki. I-bumper iyithuluzi lokuphepha elimunca futhi linciphise umthelela wangaphandle futhi livikele ingaphambili nangemuva komzimba wemoto. Eminyakeni engamashumi amabili edlule, amabhampa angaphambili nangemuva ezimoto ayenziwe kakhulu ngezinto zensimbi. Anyatheliswa ensimbini yesiteshi esingu-U enobukhulu obungaphezu kuka-3mm. Ubuso baphathwa nge-chrome futhi baphonswa noma bahlanganiswa kanye nothayela lohlaka. Ngokuthuthuka kwemboni yezimoto, i-bumper yezimoto njengedivayisi ebalulekile yokuphepha nayo isendleleni yokusungula izinto ezintsha. Ama-bumper ezimoto zanamuhla angaphambili nangemuva ngaphezu kokugcina umsebenzi wokuqala wokuvikela, kodwa futhi nokuphishekela ukuvumelana nobunye nesimo somzimba, ukuphishekela ukukhanya kwawo. Ukuze kufezwe le njongo, ama-bumper angaphambili nangemuva ezimoto enziwe ngepulasitiki, aziwa ngokuthi ama-bumper epulasitiki. I-bumper yepulasitiki yakhiwe izingxenye ezintathu, njengepuleti langaphandle, izinto zokubopha kanye nogongolo. Ipuleti langaphandle nezinto zokubopha zenziwe ngepulasitiki, kanti ugongolo lwenziwe ngeshidi eligoqiwe elibandayo elinobukhulu obungaba ngu-1.5 mm futhi linyatheliswa emseleni omise okwe-U; Ipuleti langaphandle nezinto zokubopha zinamathele emsebeni, onamathele kusikulufu sesitimela sohlaka futhi ungasuswa nganoma yisiphi isikhathi. Lolu hlobo lwe-bumper yepulasitiki lusebenzisa ipulasitiki, ngokuyisisekelo lusebenzisa uchungechunge lwe-polyester kanye nochungechunge lwe-polypropylene lwezinto ezimbili, kusetshenziswa indlela yokubumba umjovo. Kwamanye amazwe kukhona nohlobo lwepulasitiki olubizwa ngokuthi i-polycarbon ester, ukungena ngaphakathi kwe-alloy composition, indlela yokubumba i-alloy injection, ukucubungula ngaphandle kwe-bumper akugcini nje ngokuba nokuqina okuphezulu kwamandla, kodwa futhi kunezinzuzo zokushisela, futhi ukusebenza kwe-coating kuhle, inani lokuningi emotweni. I-bumper yepulasitiki inamandla, ukuqina kanye nokuhlobisa, ngokombono wokuphepha, ukushayisana kwemoto kungadlala indima ye-buffer, kuvikele umzimba wemoto wangaphambili nowangemuva, kusukela ekubukekeni, kungahlanganiswa ngokwemvelo nomzimba ube yingcezu, kuhlanganiswe kube yinto yonke, kube nomhlobiso omuhle, kube yingxenye ebalulekile yokubukeka kwemoto yokuhlobisa.
