The size of helmet shell 110 is selected such that helmet shell 110 can accommodate the remaining components of system 100 while still being securely positioned on the user's head. Where helmet shell 110 is a conventional helmet shell, it will be understood that helmet shell 110 may include its own integral, connected foam pads in addition to the pads described with respect to system 100. It will be understood that the pads described with respect to system 100 may be pads provided in addition to the pads provided in conventional helmet shells 110. Suitable helmet shells 110 for use with the present invention will be known to one of ordinary skill in the art from the description herein.

As shown in FIGS. 4-8, spacing pad 130 comprises a central portion 132 and a plurality of extending portions 134 projecting outward from the central portion. Spacing pad 130 may or may not be coupled to the interior of helmet shell 110. When spacing pad 130 is coupled to helmet shell 110, central portion 132 is coupled to a central region of the interior of helmet shell 110, such that extending portions 134 project toward the peripheral edges of helmet shell 110.

  • Raised portions 131 may have a rectangular shape, as shown in FIG. 4. However, one of ordinary skill in the art will understand that other shapes may be chosen. For example, raised portions 131 may have a square shape or a diamond shape. Raised portions 130 desirably enable air circulation across spacing pad 130 and concentrate the load from an impact on spacing pad 130. An array of raised portions 131 having a diamond shape may be particular desirable, as these raised portions 131 may enable greater flexibility of spacing pad 130.
  • spacing pad 130 may or may not be coupled to the interior helmet shell 110.

It may be desirable that the surface of spacing pad 130, including the entire lengths of extending portions 134, be adhered to the interior of helmet shell 110. The lengths of extending portions 134 may be limited, to prevent separation of extending portions 134 from helmet shell 110 during an impact that deforms helmet shell 110.
  • Absorption pads 150 may be coupled to spacing pad 130. As shown in FIG. 3, the plurality of absorption pads 150 includes a first large absorption pad 152 and a number of remaining absorption pads 154.

  • portions 240 and 250 This may be particularly desirable so that impact-resistant pad 200 may be worn by users of different head sizes. For example, when a user has a relatively small head, the gap 260 will be relatively narrow, and side portions 240 and 250 will sit close to each other (or possibly in contact with each other) when placed on the user's head. However, when a user has a relatively large head, the gap 260 will be relatively large, and side portions 240 and 250 will sit far from each other when placed on the user's head.

  • Spacing pad 530 is not adapted to be coupled to the interior of helmet shell 510. In other words, spacing pad 530 remains unconnected to helmet shell 510 (or from any other component that is connected to helmet shell 510, e.g., conventional helmet padding provided with helmet shell 510). This enables relative movement between spacing pad 530 and helmet shell 510, which may be important to assist in dissipation of the force from impacts, as explained in further detail below with respect to deflection layer 570.

  • Absorption pads 550 may be substantially the same as those described above with respect to absorption pads 150.
  • Deflection layer 570 is positioned between helmet shell 510 and spacing pad 530.
  • Deflection layer 570 is formed from a material that is less flexible (i.e. stiffer) than spacing pad 530. This enables the hard surface of deflection layer 570 to deflect a portion of the force from impacts along a surface thereof, rather than transmitting that force through deflection layer 570 to spacing pad 530. In other words, it assists in converting forces from impacts into tangential forces (which propagate along the surface) as opposed to normal forces (which propagate through the surface to the user's head).

  • Deflection layer 570 is also not coupled to the interior of helmet shell 510. This creates a "slip plane" between deflection layer 570 and helmet shell 510, and enables relative movement between the two components. Put another way, this allows independent movement of the user's head (with which spacing pad 530 and deflection layer 570 are in contact) and helmet shell 510.
  • Helmet padding system 500 may also include a plurality of deflection plates 580.

  • Deflection plates 580 are formed from the same materials as deflection layer 570.
  • the use of deflection plates 580 coupled to helmet shell 510 may further promote a sliding interface between deflection layer 570 and helmet shell 510, and thereby promote deflecting the force of impacts in a tangential direction along deflection layer 570, rather than through deflection layer 570 to spacing pad 530.

  • Deformation layer 590 may be positioned between deflection layer 570 and spacing pad 530.
