Ibhampa iyisisetshenziswa sokuphepha esimunca futhi sinciphise umthelela wangaphandle futhi sivikele ingaphambili nangemuva lomzimba wemoto. Eminyakeni engamashumi amabili edlule, amabhampa angaphambili nangemuva ezimoto ayenziwe ikakhulukazi ngezinto zensimbi. Zagxivizwa ensimbi yeshaneli emise okwe-U enogqinsi olungaphezu kuka-3 mm, futhi indawo engaphezulu yaphathwa nge-chromium. Ayeboshwe noma ashiselwe kanye nenduku yohlaka longitudinal, futhi kwakukhona igebe elikhulu nomzimba, njengokungathi ingxenye enamathiselwe. Ngokuthuthuka kwemboni yezimoto, ubhampa wezimoto njengesisetshenziswa esibalulekile sokuphepha nawo usemgwaqweni wokuqamba izinto ezintsha. Obhampa bezimoto zanamuhla ngaphambili nangemuva ngaphezu kokugcina umsebenzi wokuvikela wasekuqaleni, kodwa futhi nokuphishekela ukuzwana nobunye nokuma komzimba, ukuphishekela ukukhanya kwayo. Ukufeza le njongo, amabhampa ezimoto angaphambili nangemuva enziwe ngepulasitiki, aziwa ngokuthi ama-plastic bumpers. Ubhampa wepulasitiki wakhiwe izingxenye ezintathu: ipuleti langaphandle, i-cushioning material kanye ne-beam. Ipuleti elingaphandle kanye nempahla ye-buffer yenziwe ngepulasitiki, futhi ugongolo lwenziwe ngeshidi eligoqiwe elibandayo elinogqinsi olungaba ngu-1.5 mm futhi lwakhiwe lwaba umsele omise okwe-U; Ipuleti langaphandle kanye nokokusebenza kwe-cushioning kunamathiselwe kwi-beam, exhunywe kuzikulufu ze-frame rail futhi ingasuswa noma kunini. Lo bhampa wepulasitiki usebenzisa ipulasitiki, ngokuyisisekelo kusetshenziswa izinhlobo ezimbili zezinto, i-polyester ne-polypropylene, kusetshenziswa indlela yokubumba umjovo. Kukhona futhi uhlobo lwepulasitiki olubizwa ngokuthi i-polycarbon ester series phesheya, ukungena ekubunjweni kwengxubevange, indlela yokubumba umjovo wengxubevange, ukucubungula ngaphandle kobhampa akugcini nje ngokuba namandla aphezulu, kodwa futhi kunenzuzo yokushisela, kanye nokusebenza kokumboza kuhle, inani layanda emotweni. Ubhampa wepulasitiki unamandla, ukuqina kanye nomhlobiso, ngokombono wokuphepha, ingozi yokushayisana kwemoto ingadlala indima ye-buffer, ivikele umzimba wemoto yangaphambili nangemuva, kusukela ekubukeni kokubuka, ingahlanganiswa ngokwemvelo nomzimba. ngocezu, lonke, unomhlobiso omuhle, ube yingxenye ebalulekile yokubukeka kwemoto yokuhlobisa.
