Abstract

Claims (29)

1. A helmet comprising:

an outer shell having an interior shell surface and an opposite exterior shell surface; and

an impact absorbing layer positioned on the interior shell surface of the outer shell, wherein the impact absorbing layer includes a first impact absorbing structure having a first interior surface facing an interior cavity of the helmet, an opposite first exterior surface in contact with the interior shell surface, and a first interface that extends from the first interior surface to the first exterior surface, wherein the impact absorbing layer further includes a second impact absorbing structure having a second interior surface facing the interior cavity of the helmet, an opposite second exterior surface in contact with the interior shell surface, and a second interface that extends from the second interior surface to the second exterior surface, wherein at least part of the second interface is in lateral compression against at least part of the first interface;

wherein the first impact absorbing structure includes a first engagement portion that engages the outer shell such that the first impact absorbing structure is held in lateral compression between the at least part of the first interface and the first engagement portion.

2. A helmet as claimed in claim 1 , wherein the outer shell comprises a vent opening defined by a vent edge, and wherein the first engagement portion engages the vent edge.

3. A helmet as claimed in claim 1 , wherein the second impact absorbing structure comprises an energy-absorbing layer and an inner shell secured to an outer surface of the energy-absorbing layer, wherein the inner shell includes a second engagement portion.

4. A helmet as claimed in claim 3 , wherein the inner shell comprises a material having a higher density than the energy-absorbing layer.

5. A helmet as claimed in claim 4 , wherein the inner shell comprises polycarbonate and the energy-absorbing layer comprises expanded polystyrene.

6. A helmet as claimed in claim 1 , wherein the outer shell comprises an upper wall, a rear wall, a left wall and a right wall, wherein the first impact absorbing structure comprises an upper impact absorbing structure adjacent the upper wall and the second impact absorbing structure comprises a rear impact absorbing structure adjacent the rear wall.

7. A helmet comprising:

an outer shell having a first receiving portion; and

an impact absorbing layer positioned on an interior side of the outer shell, the impact absorbing layer comprising a first impact absorbing structure having a first engagement portion and a second impact-absorbing structure having a second engagement portion spaced from the first engagement portion, wherein the first impact absorbing structure is mechanically secured to the outer shell by the first engagement portion engaging the first receiving portion and the second impact-absorbing structure is mechanically secured to the outer shell by the second engagement portion engaging a second receiving portion spaced from the first receiving portion;

wherein the first receiving portion comprises a vent or a recess in the outer shell, wherein the second impact-absorbing structure includes an inner shell, and wherein the inner shell includes the second engagement portion;

wherein the first impact absorbing structure is held in lateral compression against the second impact absorbing structure.

8. A helmet as claimed in claim 7 , wherein the first receiving portion comprises a vent edge defining at least a portion of the vent or recess.

9. A helmet as claimed in claim 8 , wherein the second receiving portion comprises a recess in the outer shell.

10. A helmet as claimed in claim 7 , wherein the first receiving portion is along a top of the helmet, and wherein the second receiving portion is along a rear of the helmet.

11. A helmet as claimed in claim 7 , wherein the second impact absorbing structure comprises an energy-absorbing layer and wherein the inner shell is secured to an outer surface of the energy-absorbing layer.

12. A helmet as claimed in claim 11 , wherein the inner shell comprises a material having a higher density than the energy-absorbing layer.

13. A helmet as claimed in claim 12 , wherein the inner shell comprises polycarbonate and the energy-absorbing layer comprises expanded polystyrene.

14. A helmet as claimed in claim 7 , wherein the impact absorbing layer defines a rear vent along a rear of the helmet that is separate from the first receiving portion, wherein the helmet further comprises an adjusting assembly for adjustably securing the helmet to a user's head, the adjusting assembly including an adjusting input movable to adjust a size of the helmet, the adjusting input being positioned at least partially in the rear vent.

15. A helmet comprising:

an outer shell having an interior shell surface and an opposite exterior shell surface; and

an impact absorbing layer positioned on the interior shell surface of the outer shell, wherein the impact absorbing layer includes a first impact absorbing structure having a first interior surface facing an interior cavity of the helmet, an opposite first exterior surface in contact with the interior shell surface, and a first interface that extends from the first interior surface to the first exterior surface, wherein the impact absorbing layer further includes a second impact absorbing structure having a second interior surface facing the interior cavity of the helmet, an opposite second exterior surface in contact with the interior shell surface, and a second interface that extends from the second interior surface to the second exterior surface, wherein at least part of the second interface is in lateral compression against at least part of the first interface;

wherein the outer shell comprises an upper wall, a rear wall, a left wall and a right wall, wherein the first impact absorbing structure comprises an upper impact absorbing structure adjacent the upper wall and the second impact absorbing structure comprises a rear impact absorbing structure adjacent the rear wall.

16. A helmet as claimed in claim 15 , wherein the first impact absorbing structure includes a first engagement portion that engages the outer shell such that the first impact absorbing structure is held in lateral compression between the at least part of the first interface and the first engagement portion, wherein the outer shell comprises a vent opening defined by a vent edge, and wherein the first engagement portion engages the vent edge.

17. A helmet as claimed in claim 16 , wherein the second impact absorbing structure comprises an energy-absorbing layer and an inner shell secured to an outer surface of the energy-absorbing layer, wherein the inner shell includes a second engagement portion.

18. A helmet as claimed in claim 17 , wherein the inner shell comprises a material having a higher density than the energy-absorbing layer.

19. A helmet as claimed in claim 18 , wherein the inner shell comprises polycarbonate and the energy-absorbing layer comprises expanded polystyrene.
