Abstract: Formed by a rear shield (100), which rests on the shoulders and the upper part of the back, and two front shields (251) (252), which rest on the upper front part of the torso, one on each side of the neck. Said front shields (251) (252) are joined to the rear one (100) by means of articulation, for example hinges (301) (302), whose axes of rotation are oriented upwards, towards the rear and towards the centre, in such a way that their point of intersection (01) is located above and behind them. Both the front shields (251) (252) and the rear one (100) can be fixed to the garment via union zones, and thanks to the special orientation of the axes of the hinges (301) (302), it is possible for the neck protector (001) to be put on and taken off together with any garment. The configuration of the protector permits a rapid fastening device to be incorporated for the various elements, along with a system of adjustment to different sizes.
