Intebe zo mu bironi nkinkweto, ikintu kimwe nuko dukoresha umwanya munini, birashobora kwerekana umwirondoro wawe nuburyohe, bigira ingaruka kumyumvire yumubiri;Itandukaniro nuko dushobora kwambara inkweto zitandukanye kugirango dukore, ariko dushobora kwicara gusa ku ntebe y'ibiro yatanzwe na shobuja.
Wigeze ukeka ko igitera ububabare bw'umugongo ari imiterere y'intebe y'ibiro byawe, ukibwira ko kubihindura gusa byakuraho ububabare?Wigeze wibaza niba intebe zo mu biro bya plastiki, nubwo ari mbi, ziruta iz'ikawa kuri Starbucks?Turashobora gukoresha porogaramu yikoranabuhanga kugirango dushushanye inshuti ibirometero ibihumbi n'ibihumbi intebe y'ibiro, ariko ntidushobora guha mugenzi wawe intebe nyayo, kuki ergonomique ya 1980 yashushe?Niba barigeze batekereza gushushanya intebe nziza？
Intebe yambere igenzurwa kubyo abantu bakeneye yagaragaye muri 3000 mbere ya Yesu.Nubwo intebe iri ku ishusho iri hejuru yimyaka ibihumbi n'ibihumbi kurenza intebe ya mbere yicaye muri Egiputa, iyi ntebe, nko mu 712 mbere ya Yesu, itanga igitekerezo cyuko kuryama gake byafasha kuringaniza umubiri.
Igishushanyo n'ibisobanuro by'intebe za mbere muri Egiputa ya kera birasa n'intebe z'iki gihe: amaguru ane, umusingi, n'umugongo uhagaze.Ariko nk'uko Jenny Pynt na Joy Higgs babivuze, ahagana mu mwaka wa 3000 mbere ya Yesu, icyicaro cyahinduwe kugira ngo abakozi barusheho gutanga umusaruro: cyari gifite amaguru atatu, umusingi ucuramye, kandi cyegamye imbere gato, bisa nkaho byoroshye gukoresha inyundo.Hamwe na hamwe, basohoye Imyaka 5000 yo Kwicara: Kuva 3000 mbere ya Yesu kugeza 2000 nyuma ya Yesu.
Mugihe cyimyaka ibihumbi bike yakurikiyeho, habaye impinduka nyinshi mubyicaro, kuva kuntebe yumwami kugeza ku ntebe yumukene, bimwe bifatika, bimwe bikozwe mu mitako, n'intebe nke zagenewe cyane cyane imyitozo ngororamubiri muri ubwenge.Ahagana mu 1850 ni bwo itsinda ry’abashakashatsi b’abanyamerika batangiye gukora ubushakashatsi ku buryo uko igihagararo cyaba kimeze kose, icyicaro gishobora kwemeza ubuzima n’umutangabuhamya.Iyi myanya yabugenewe idasanzwe yitwa "intebe z'ipatanti" kubera ko abayishushanyijeho.
Kimwe mu bishushanyo mbonera by’impinduramatwara ni intebe ya Tomasi E. Warren yicaye ku ntebe, ifite icyuma gikozwe mu cyuma hamwe n’igitambaro cya veleti, gishobora guhindurwa no kugororwa mu cyerekezo icyo ari cyo cyose kandi cyerekanwe bwa mbere mu imurikagurisha ryabereye i Londres mu 1851.
Jonathan Olivares avuga ko intebe yisoko ya centripetal ifite ibintu byose biranga aintebe y'ibiro bigezweho, usibye inkunga ishobora guhinduka mukibuno.Ariko intebe yakiriye ibitekerezo bibi mpuzamahanga kuko byari byiza kuburyo byafatwaga nkibitemewe.Jenny Pynt, mu nyandiko ye yise "Icyicaro cya Patent cyo mu kinyejana cya cumi n'icyenda", asobanura ko mu gihe cya Victorian, guhagarara muremure, kugororotse, no kuticara ku ntebe ufite umugongo byafatwaga nk'icyubahiro, ubushake, bityo bikaba umuco.
Nubwo "icyicaro cy'ipatanti" cyabajijwe, mu mpera z'ikinyejana cya 19 cyari igihe cya zahabu cyo gushushanya imyanya mishya.Ba injeniyeri n'abaganga bakoresheje ibyo bazi kubijyanye no kugenda kwumubiri kugirango bakore intebe zo mu biro zibereye imirimo nko kudoda, kubaga, kwisiga, no kuvura amenyo.Iki gihe cyabonye ubwihindurize bwintebe: guhindagurika inyuma yuburebure nuburebure, hamwe nibintu bya ergonomic bitazamenyekana nyuma yimyaka irenga 100."Mu myaka ya 1890, intebe yo kogosha yashoboraga kuzamurwa, kumanurwa, kuryama no kuzunguruka."Jenny yaranditse ati: "Mu kinyejana cya 20 rwagati ni bwo ibyo bishushanyo byakoreshwaga ku ntebe zo mu biro."
