Ladite bande de protection pour vertèbres cervicales présente un corps de bande de protection semblable à une bande, d'une longueur et d'une largeur suffisantes pour entourer la partie généralement entière de la partie cervicale de l'utilisateur, ainsi qu'un moyen de fixation pouvant se désengager. Lors de l'utilisation, le moyen de fixation maintient le corps de bande de protection dans un état d'utilisation tel que ledit corps de la bande de protection est incurvé le long du pourtour de la partie cervicale de l'utilisateur. Le corps de bande de protection est un corps stratifié présentant une plaque centrale et un corps d'amortissement. Le corps d'amortissement est composé d'une partie principale de corps d'amortissement et d'une partie de bord de corps d'amortissement. La partie principale de corps d'amortissement est ajustée au côté antérieur ou au côté postérieur de la plaque centrale, dont le côté se situe sur le côté de la partie cervicale au moins durant l'utilisation. La partie de bord du corps d'amortissement couvre les bords supérieur et inférieur de la plaque centrale.
