Iyo bumper chishandiso chekuchengetedza chinotora uye kuderedza kukanganiswa kwekunze uye inodzivirira kumberi nekumashure kwemuviri wemotokari. Makore makumi maviri apfuura, mabhampa epamberi uye kumashure emotokari ainyanya kugadzirwa nesimbi. Iwo akadhindwa muU-shaped chiteshi simbi ine ukobvu hunodarika 3 mm, uye pamusoro pacho chaibatwa nechromium. Aive akarukwa kana kuti kubatanidza nedanda rehurefu refuremu, uye pakanga paine mukaha mukuru nemuviri, sokunge chikamu chakabatanidzwa. Nekuvandudzwa kweindasitiri yemotokari, bumper yemotokari sechinhu chakakosha chekuchengetedza chiri munzira yekuvandudza. Mazuva ano mota kumberi uye kumashure mabumpers mukuwedzera pakuchengetedza iyo yekutanga kuchengetedza basa, asiwo kutsvaga kuwirirana uye kubatana nechimiro chemuviri, kutsvaga kwayo kureruka. Kuti uite chinangwa ichi, kumberi uye kumashure mabumpers emotokari anogadzirwa nepurasitiki, inozivikanwa sepurasitiki bumpers. Iyo purasitiki bumper inoumbwa nezvikamu zvitatu: yekunze ndiro, cushioning zvinhu uye danda.
