A work or sports protective helmet, with a structure having a substantially convex outer surface; a substantially concave inner surface adapted to receive a user's head in engagement is provided. The helmet also has two coupling and decoupling elements for engagement an accessory, such as a visor, a mask, a net or a similar accessory, each of which can be engaged on a lateral portion of the outer surface of structure. Each coupling and decoupling element can be removed from the helmet and has a body having a coupling mechanism which allows the engagement and the disengagement of the accessory to/from the helmet when the coupling and decoupling elements are engaged on the latter.

1. A helmet, comprising a structure having: at least one substantially convex outer surface; andat least one substantially concave inner surface adapted to receive the user's head in engagement;wherein the helmet having two coupling and decoupling elements for engaging at least one accessory, which is engageable on a lateral portion of the outer surface of the structure, each coupling and decoupling element being removable from the helmet and having a body having at least one coupling mechanism that allows the engagement and disengagement of the accessory to/from the helmet when the coupling and decoupling elements are engaged on the latter,each element for coupling and decoupling the accessory comprising at least one attachment portion insertable in at least one respective attachment opening obtained on the helmet, the coupling mechanism of each element for coupling and decoupling the accessory comprises: at least one engagement portion projecting from the respective body transversely with respect to the main development of the respective attachment portion, the engagement portion being shaped so as to receive a respective engagement portion of each accessory in engagement, whereon an engagement seat is obtained, the engagement seat being at least partially counter-shaped with respect to the engagement portion of the coupling mechanism of the respective coupling and decoupling element;at least one fixed coupling abutment transversely projecting from the engagement portion of the coupling mechanism, the engagement portion of each accessory being interposed between the respective fixed coupling abutment and the respective body of the latter when it is in the mounted condition on the respective coupling and decoupling element; andat least one movable coupling abutment transversely projecting from the engagement portion of the coupling mechanism, on the opposite side with respect to the fixed coupling abutment, the movable coupling abutment being switchable between a first position, in which it projects at least partially from the engagement portion of the coupling mechanism in order to hold a respective engagement portion of each accessory when the latter is mounted on the respective coupling and decoupling element, and a second position, in which it does not project from the engagement portion of the coupling mechanism allowing the application of an accessory on the respective coupling and decoupling element or the removal of the same from the respective coupling or decoupling element. 2. The helmet according to claim 1, wherein each attachment opening is obtained through the perimeter edge of the helmet and develops substantially parallel or tangential with respect to the outer surface of the latter, thus the engagement of the respective element for coupling and decoupling the accessory is performed along a direction substantially parallel or tangential with respect to the outer surface of the helmet. 3. The helmet according to claim 1, wherein the attachment portion of each element for coupling and decoupling the accessory is insertable in a snap-fit manner into the respective attachment opening of the helmet. 4. The helmet according to claim 1, wherein the attachment portion of each element for coupling and decoupling the accessory is engageable by interference in the respective attachment opening of the helmet. 5. The helmet according to claim 1, wherein each attachment opening of the helmet is substantially square-shaped, and the attachment portion of each element for coupling and decoupling the accessory is substantially plate-shaped with a substantially square-shaped section. 6. The helmet according to claim 5, wherein the attachment portion of each coupling and decoupling element extends cantilevered from the body of the latter, the attachment portion tapering away from the body and ending with an enlarged end defining at least one abutment tooth for engaging a respective abutment edge of the respective attachment opening arranged inside the helmet. 7. The helmet according to claim 1, wherein the attachment portion of each element for coupling and decoupling the accessory is elastically deformable, at least transversely with respect to its longitudinal extension, in order to guarantee its snap-fit engagement in the respective attachment opening of the helmet and the disengagement from the same. 8. The helmet according to claim 1, wherein the movable coupling abutment of the coupling mechanism of each element for coupling and decoupling the accessory is operatively associated with an elastic return means, that maintains or returns the respective movable coupling abutment to the first position, in the absence of forces capable of leading the latter towards the second position. 9. The helmet according to claim 8, wherein the movable abutment element has a profile, in longitudinal section, having at least one first inclined surface tapering towards the body of the respective coupling and decoupling element away from the respective engagement portion of the respective coupling mechanism, the first inclined surface switching the respective movable coupling abutment from the first position to the second position when an engagement portion of an accessory is fitted on the respective engagement portion of the respective coupling mechanism of the respective coupling and decoupling element and pushed towards the body of the latter. 10. The helmet according to claim 9, wherein the movable abutment element has a profile, in longitudinal section, having a second inclined surface tapering from the body of the respective coupling and decoupling element away from the respective engagement portion of the respective coupling mechanism, the second inclined surface switching the respective movable coupling abutment from the first position to the second position when an engagement portion of an accessory, fitted on the respective engagement portion of the respective coupling mechanism of the respective coupling and decoupling element, is pulled away from the body of the respective coupling and decoupling element, the inclination of the second surface of the movable coupling abutment being such as to require in order to switch the latter from the first position to the second position—a force greater than the force required for performing such switching by acting on the first surface of the movable coupling abutment, thus the application, by pushing, of the accessory on the coupling and decoupling elements is easier than the removal, by tearing, of the accessory from the coupling and decoupling elements. 11. The helmet according to claim 10 wherein the movable coupling abutment of the coupling mechanism of each coupling and decoupling element comprises at least one gripping portion for manually switching the same from the first position to the second position. 12. The helmet according to claim 1, wherein the accessory is a face protection accessory selected from the group consisting of a visor, a mask, a net, and similar accessories. 13. The helmet according to claim 12, further comprising the face protection accessory. 14. The helmet according to claim 1, wherein the helmet is a work or sports protective helmet.
