Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) It is now reported, as an example, the description of a preferred, but not exclusive, embodiment of an anti-release protective helmet, in particular for sports use, in accordance with the present invention. Such a description shall be carried out in the rest of the description with reference to the attached drawings, that have been given purely as an indication and therefore not for limiting purposes, in which:

(2) FIG. 1 shows an exploded embodiment of an anti-release protective helmet according to the present invention;

(3) FIG. 2 shows a detail of the helmet of FIG. 1;

(4) FIGS. 3-5 show the helmet of FIG. 1 in different configurations that can be obtained without any manual adjustment; and

(5) FIGS. 6-8 show an embodiment of a spring element that makes it possible to achieve the configurations that are shown in FIGS. 3-5 without any manual adjustment.

DETAILED DESCRIPTION OF THE INVENTION

(6) With reference to the attached figures, reference numeral 10 wholly indicates an anti-release protective helmet according to the present invention.

(7) The anti-release protective helmet 10 according to the present invention comprises: a shell structure 11 that is shaped so as to at least partially cover the head of a user and is configured so as to protect it from bangs at the cranium portion substantially starting from the eye arch up to the nuchal area both on top and laterally; and a nape-rest element 12 that is fixedly connected to the shell structure at the nuchal area of the user.

(8) Since the shell structure 11 is of the known type and does not directly concern peculiar aspects of the invention, both the materials and the accessory elements that form it shall not be listed for the sake of clarity of the description.

(9) The nape-rest element 12, as shall become clearer from the rest of the description, has the main function of making the worn helmet stable and of preventing it from accidentally pulling off by adhering to the nape of the user.

(10) The shell 11 and the nape-rest element 12 are visible in FIG. 1 which shows an exploded view of an embodiment of an anti-release protective helmet 10 according to the present invention.

(11) According to the present invention, and as visible in FIGS. 3-5, the nape-rest element 12 is constrained to the shell structure 11 in a movable manner between a fitting position of the helmet 10, in which it is in substantial contact with the inner rear wall 14 of the shell structure 11, and a use position of the helmet 10 in which it is separated from the inner rear wall 14 of the shell structure 11 and in substantial contact with the nuchal area of the user wearing the helmet 10.

(12) Even more in particular, the helmet 10 comprises a spring element 13 that is configured so as to force the nape-rest element 12 into its use position in which it is separated from the inner rear wall 14 of the shell structure 11 and in substantial contact with the nuchal area of the user wearing the helmet 10.

(13) In such a way, during the fitting of the helmet, the spring 13 allows the nape-rest element 12 to retract so as to pass over the occipital protuberance and then it automatically brings it into a position in which it adheres to the nape of the user without any manual adjustment.

(14) As shown, the nape-rest element 12 is substantially a C-shaped element with an inner profile that is configured so as to adhere, during use, to the nape of the user and with an outer profile that is configured so as to adhere, when fitted, to the inner rear wall 14 of the shell structure 11.

(15) The spring 13, as visible in FIG. 2, is a leaf spring that is arranged between the nape-rest element 12 and the inner rear wall 14 of the shell structure 11.

(16) More in detail, in the constructive example shown, the spring 13 comprises a C-shaped leaf 15 in which the central portion 16 is in substantial contact with the inner rear wall 14 of the shell structure 11 and the lateral portions 17 are separated from the inner rear wall 14 and are directed towards the inside of the shell structure 11.

(17) In such a way, when they are compressed, the lateral portions 17 act on the nape-rest element 12 so as to push it inwards with respect to the helmet 11 and therefore adhering to the nape of the user.

(18) As visible in FIGS. 6-8, the spring 13 comprises a stem portion 18 that extends from the central portion in a direction that is orthogonal with respect to the C-shaped leaf 15.

(19) The stem portion 18 comprises a plurality of sections 19, 19, 19 with a variable inclination and is constrained to the shell structure 11, for example by means of a pocket for receiving said stem.

(20) The spring 13 is then fixedly connected to the nape-rest element 12, for example by means of a screw.

(21) Finally, the nape-rest element 12 comprises, at the back, a lowered seat for receiving the C-shaped leaf 15.

(22) It has thus been seen that an anti-release protective helmet according to the present invention achieves the aforementioned highlighted purposes.

(23) Very briefly, the following advantages can be listed: greater safety for the user due to the greater adherence to the nuchal area and to the greater ability of the helmet to remain secure and stable on the head thanks to the automatic and fast closing system; perfect adaptability to the shape of the nuchal area; increased comfort; ease of use.

(24) The anti-release protective helmet of the present invention thus conceived can undergo numerous modifications and variants, all covered by the same inventive concept; moreover, all the details can be replaced by technically equivalent elements. In practice, the materials used, as well as their sizes, can be of any type according to the technical requirements.
