Helmet with removable chin guard
The present invention relates to a protective helmet ( 1 ) comprising a chin guard ( 11 ) removable from an operating position, for protecting the chin, characterized in that the shell ( 21 ) of the helmet ( 1 ) is provided with a portion ( 31 ) for coupling with the chin guard ( 11 ) when removed.
1. A protective helmet comprising:
a shell; and
a chin guard removable from the shell, the chin guard having an operating position for protecting the chin, and a separated position for exposing the chin;
wherein the shell of said helmet is provided with a coupling portion adapted to support said chin guard when the chin guard is in the separated position;
wherein to switch from the operating position to the separated position, the chin guard must be disconnected from the shell and reattached to the shell at a different position on the shell.
2. The helmet according to claim 1 , wherein when in the separated position the chin guard encircles a back portion of said shell.
3. The helmet according to claim 1 , wherein said coupling portion is positioned in a different position from said operating position.
4. The helmet according to claim 3 , wherein said coupling portion is positioned in a position opposite said operating position.
5. The helmet according to claim 1 , wherein said coupling portion is shaped so as to at least partly house said chin guard.
6. The helmet according to claim 1 , wherein said coupling portion is shaped so as to fully house said chin guard.
7. The helmet according to claim 1 , wherein said coupling portion is provided with first means for locking and unlocking said chin guard in said coupling portion.
8. The helmet according to claim 7 , wherein said chin guard is provided with second means for locking and unlocking said chin guard in said coupling portion and/or with said shell in operating position.
9. The helmet according to claim 8 , wherein said first means and said second means are correspondent and produce locking and unlocking of said chin guard in said coupling portion.
10. The helmet according to claim 2 , wherein said coupling portion is shaped so as to at least partly house said chin guard.
11. The helmet according to claim 3 , wherein said coupling portion is shaped so as to at least partly house said chin guard.
12. The helmet according to claim 2 , wherein said coupling portion is provided with first means for locking and unlocking said chin guard in said coupling portion.
13. The helmet according to claim 3 , wherein said coupling portion is provided with first means for locking and unlocking said chin guard in said coupling portion.
14. The helmet according to claim 4 , wherein said coupling portion is provided with first means for locking and unlocking said chin guard in said coupling portion.
15. The helmet according to claim 5 , wherein said coupling portion is provided with first means for locking and unlocking said chin guard in said coupling portion.
16. The helmet according to claim 2 , wherein said chin guard is provided with means for locking and unlocking said chin guard in said coupling portion and/or with said shell in operating position.
17. The helmet according to claim 3 , wherein said chin guard is provided with means for locking and unlocking said chin guard in said coupling portion and/or with said shell in operating position.
18. A protective helmet switchable between a jet helmet configuration and a full helmet configuration, comprising:
a shell having a front side, lateral sides, and a back side;
a recess in the back side of the shell;
a chin guard selectively connectable to the shell;
the shell and the chin guard having at least two operating configurations, comprising:
a full helmet configuration in which the chin guard is connected to the lateral sides of the shell to protect a chin area;
a jet helmet configuration in which the chin guard is mounted in the recess in the back side of the shell.
19. The helmet of claim 18 , wherein the helmet is switched from the full helmet configuration to the jet helmet configuration by disconnecting the chin guard from the lateral sides and mounting the chin guard in the recess.
20. The helmet of claim 18 , wherein the recess is shaped so as to completely contain the chin guard when in the jet helmet configuration.
21. The helmet of claim 18 , wherein when in the jet helmet configuration the chin guard and the shell form a continuous surface.
22. The helmet of claim 18 , further comprising:
the chin guard including a first pair of hooks;
the shell including a second and third pair of hooks;
wherein in the full helmet configuration the first set of hooks engage the second pair of hooks;
wherein in the jet helmet configuration the first set of hooks engage the third pair of hooks.
