Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
129 words
An integral helmet especially suited for sports use, provided with an annular unlockable body made of elastically yielding material, said annular body comprising of at least two segments, the first segment (B 3 ) being secured to the aperture of the body of the helmet (A), the second segment (B 1 -B 2 ) being retained movably as to said first segment by hinges (26), the top edge of said segments (B 1 , B 2 ) being provided with locking elements (14) apt to engage it with the aperture of the helmet to ensure resistant continuity between the helmet body and said annular body, the adjacent ends of said tiltable segment B 1 and B 2 being externally locked to each other by means of a latch (K).
Claim 2
Dependent Claim
129 words
An integral helmet especially suited for sports use, provided with an annular unlockable body made of elastically yielding material, said annular body comprising of at least two segments, the first segment (B 3 ) being secured to the aperture of the body of the helmet (A), the second segment (B 1 -B 2 ) being retained movably as to said first segment by hinges (26), the top edge of said segments (B 1 , B 2 ) being provided with locking elements (14) apt to engage it with the aperture of the helmet to ensure resistant continuity between the helmet body and said annular body, the adjacent ends of said tiltable segment B 1 and B 2 being externally locked to each other by means of a latch (K).
Claim 3
Dependent Claim
42 words
An integral helmet according to claim 1 wherein the lower edges (10, 12) of said segments (B 1 B 2 ) are at least partly folded over inwardly to cooperate, preferably by means of a padding, with the wearer's jaw and nape.
Claim 4
Dependent Claim
67 words
An integral helmet according to claim 1 wherein the top edge (14) of the second segment (B 1 -B 2 ) is provided with at least one ledge (or groove) apt to engage with at corresponding groove (or ledge) on the edge of the aperture of the helmet body aperture to provide thereby a suitable firm connection between said body and jaw segment in the wearing position.
Claim 5
Dependent Claim
80 words
An integral helmet according to claim 3 wherein latch (K) is on an angle zone of annular body (B), that is provided with an angular slider (30) one of the fins of which cooperates slidably with guideways (34-35) on the adjacent ends of said annular body and with latching means (34-35-36) for tiltable segment (B 1 -B 2 ) while the other fin (40) of said slider (30) is provided with connecting and locking means (44-45) for said tiltable segment.
Claim 6
Dependent Claim
36 words
An integral helmet according to claim 1 wherein the transversal adjacent edges (28) of the two tiltable elements B 1 and B 2 are provided with grooves or ledges which may be locked to each other.
Claim 7
Dependent Claim
34 words
An integral helmet according to claim 1 wherein the first segment (B 3 ) is provided, along a part of its top edge, with at least one fin (20), securable to helmet body (A).
Claim 8
Dependent Claim
28 words
An integral helmet according to claim 1 wherein the first segment (B 3 ), secured to helmet body (A), has an angular width comprised between 10° and 20°.
Claim 9
Dependent Claim

An integral helmet according to claim 8 wherein hinge (26) between fixed segment B 3 and tiltable segment (B 1 -B 2 ) is provided with one or more substantially parallel impressions extending transversally with respect to the generatrix of said annular body.
Claim 11
Dependent Claim
50 words
An integral helmet according to claim 1 wherein the angular width of the first segment (B 3 ) has a reduced width so as to retain the joint zone of hinge (26) for the two tiltable elements (B 1 and B 2 ) which may be secured by latch (K).
Claim 12
Dependent Claim
24 words
An integral helmet according to claim 1 wherein the axis of hinge/hinges (26) is located on the longitudinal and/or transversal plane of the helmet.
Claim 13
Dependent Claim
28 words
An integral helmet according to claim 1, wherein the axis of hinge (26b) is located on the rear of the mid-part of the aperture of the helmet body.
Claim 14
Dependent Claim
80 words
An integral helmet according to claim 1 wherein latch (K) is on an angle zone of annular body (B), that is provided with an angular slider (30) one of the fins of which cooperates slidably with guideways (34-35) on the adjacent ends of said annular body and with latching means (34-35-36) for tiltable segment (B 1 -B 2 ) while the other fin (40) of said slider (30) is provided with connecting and locking means (44-45) for said tiltable segment.
Claim 15
Dependent Claim
78 words
An integral helmet according to claim 13 wherein the slider (30) is provided, along its longitudinal edges, with opposite slots (36) which engage slidably a pair of prismatic projecting parts (34-35), the elements of said pairs being provided on the adjacent edges of the ends of the segments forming annular body (B), one of said segments being longer than the other, to retain said slider when segments (B 1 -B 2 ) are disengaged one from the other.
Claim 16
Dependent Claim
38 words
An integral helmet according to claim 14 wherein lower fin (38) of slider (30) is provided at its end with a pair of teeth (40) apt to engage pins (42), secured to the segments of annular body (B).
