Bumper y'imodoka ni igikoresho cy'umutekano cyinjiza kandi kigagabanya ingaruka z'inyuma kandi kikarinda imbere n'inyuma by'umubiri w'imodoka. Igikoresho gitanga umusego iyo imodoka cyangwa umushoferi agonzwe n'impanuka. Bumper ya pulasitiki igizwe n'isahani y'inyuma, ibikoresho byo gukingira n'umusego w'umusaraba. Isahani y'inyuma n'ibikoresho byo gukingira bikozwe muri pulasitiki, kandi umusego w'umusaraba ushyirwaho urupapuro rukonje rufite ubugari bwa mm 1.5 kugira ngo habeho umuyoboro ufite ishusho ya U; Isahani y'inyuma n'ibikoresho byo gukingira bifatanye n'umusego w'umusaraba, uhuzwa n'umusego w'inyuma hakoreshejwe vis kandi ushobora gukurwaho igihe icyo ari cyo cyose. Plastike ikoreshwa muri iyi bumper ya pulasitiki muri rusange ikozwe mu bikoresho bya polyester na polypropylene hakoreshejwe injection molding. Bumper y'imodoka ni igikoresho cy'umutekano cyinjiza kandi kigagabanya ingaruka z'inyuma kandi kikarinda ibice by'imbere n'inyuma by'umubiri w'imodoka. Mu myaka makumyabiri ishize, bumper y'imbere n'inyuma y'imodoka ahanini yari ikozwe mu byuma. Byashyizwe mu cyuma gifite ishusho ya U gifite ubugari burenga mm 3. Ubuso bwari bukozwe muri chrome, bupfundikiye cyangwa busudikanywe n'umurambararo w'umukara, kandi hari icyuho kinini hagati y'umubiri, cyasaga n'aho ari ikindi kintu cy'inyongera. Bitewe n'iterambere ry'inganda z'imodoka, bumper y'imodoka, nk'igikoresho cy'ingenzi cy'umutekano, nayo iri mu nzira yo guhanga udushya. Bumper y'imbere n'inyuma y'imodoka muri iki gihe ntikomeza gusa imikorere yo kurinda umwimerere, ahubwo inakurikirana ubwumvikane n'ubumwe n'imiterere y'umubiri, kandi ikurikirana ubworoheje bwayo. Kugira ngo iyi ntego igerweho, bumper y'imbere n'iy'inyuma y'imodoka ikozwe muri pulasitiki, yitwa bumper ya pulasitiki. Bumper ya pulasitiki igizwe n'isahani yo hanze, ibikoresho byo gupfuka n'umurambararo w'umukara. Isahani yo hanze n'ibikoresho byo gupfuka bikozwe muri pulasitiki, kandi umurambararo w'umukara ushyirwaho urupapuro rukonje rufite ubugari bwa mm 1.5 kugira ngo habeho umuyoboro ufite ishusho ya U; Isahani yo hanze n'ibikoresho byo gupfuka bifatanye n'umurambararo w'umukara, uhujwe n'umurambararo w'umukara w'umukara hakoreshejwe vis kandi ushobora gukurwaho igihe icyo ari cyo cyose. Plastike ikoreshwa muri iyi bumper ya pulasitiki muri rusange ikozwe muri polyester na polypropylene hakoreshejwe injection molding. Hariho kandi ubwoko bwa pulasitiki yitwa sisitemu ya polycarbonate mu mahanga, yinjiza mu buryo bw'ibumba igakoresha uburyo bwo gushushanya imashini. Ibumba ryatunganyijwe ntabwo rifite imbaraga nyinshi gusa, ahubwo rifite n'akamaro ko gusudira, ahubwo rinagira ubushobozi bwo gusiga irangi, kandi rikoreshwa cyane ku modoka. Ibumba rya pulasitiki rifite imbaraga, gukomera no gushariza. Mu rwego rw'umutekano, rishobora kugira uruhare mu gihe habaye impanuka no kurinda umubiri w'imbere n'uw'inyuma. Mu rwego rw'isura, rishobora guhuzwa n'umubiri mu buryo busanzwe maze rigahinduka ikintu cyose. Rifite imitako myiza kandi ryabaye igice cy'ingenzi mu gushariza imiterere y'imodoka.
