A helmet has a rigid shell and an adjustable liner connected to the shell. The liner has a plurality of pads located in the shell cavity. The pads are movable with respect to the interior shell surface between a first position near the interior shell surface and a second position further away. In some embodiments, pads are biased towards their second position and the act of the wearer inserting his head into the helmet causes the pads to move towards their first position while remaining biased against the head of the wearer to assist in causing the liner to conform to the head of the wearer. In other embodiments, constriction of the pads moves pads from their second position to their first position, for this same purpose. In other embodiments, pads having both of the aforementioned characteristics are present.

The helmet of claim 1, wherein two of the first plurality of floating pads are hingedly interconnected. 3. The helmet of claim 2, wherein the hinged interconnection between the two of the first plurality of floating pads is itself movable with respect to the interior shell surface independently of movement of the two of the first plurality of floating pads relative to the interconnection. 4. The helmet of claim 3, wherein at least one pad of the first plurality of floating pads is movable between its second position and its first position independently of movement of at least one other pad of the first plurality of floating pads from its second position to its first position. 5. The helmet of claim 1, wherein each of the first plurality of floating pads is attached to the shell solely via at least one of the hinged connections to the at least one fixed pad. 6. The helmet of claim 1, wherein at least some of the first plurality of floating pads are movable between their second position and their first position independently of movement of others of the first plurality of floating pads from their second position to their first position. 7. The helmet of claim 1, wherein the helmet is supported on the head of the wearer at least by a portion of some of the first plurality of floating pads abutting the interior shell surface after the movement caused by the act of the wearer inserting his head into the helmet. 8. A helmet comprising: a rigid shell having an interior shell surface defining a cavity within the shell for receiving a head of a wearer of the helmet,an upper shell portion covering at least a majority of a frontal portion and parietal portions of the head of the wearer when the helmet is being worn,a left side shell portion covering at least a majority of a left temporal portion of the head of the wearer when the helmet is being worn,a right side shell portion covering at least a majority of a right temporal portion of the head of the wearer when the helmet is being worn, anda lower rear shell portion covering at least a majority of an occipital portion of the head of the wearer when the helmet is being worn; andan adjustable liner connected to the shell, the liner including a first plurality of floating pads located in the cavity in juxtaposition with the upper shell portion of the helmet, each of the first plurality of floating pads being movable with respect to the interior shell surface between a first position near the interior shell surface and a second position further away from the interior shell surface than the first position,a second plurality of pads including a left temporal floating pad located in the cavity in juxtaposition with the left shell portion of the helmet,a right temporal floating pad located in the cavity in juxtaposition with the right shell portion of the helmet, andan occipital pad in juxtaposition with the lower rear shell portion of the helmet, at least the left temporal floating pad and the right temporal floating pad being movable with respect to the interior shell surface between a first position near to the interior shell surface and a second position further away from the interior shell surface than the first position; andan encircling portion encircling the frontal portion, the left temporal portion, the right temporal portion and the occipital portion of the head of the wearer when the helmet is being worn, the encircling portion including at least the left temporal floating pad, the right temporal floating pad, the occipital pad and an elongated member operatively connected with at least the left temporal floating pad and the right temporal floating pad such that constriction of the encircling portion includes at least the left temporal floating pad and the right temporal floating pad moving from their respective first positions towards their respective second positions to assist in causing the liner to conform to the head of the wearer. 9. The helmet of claim 8, wherein constriction of the elongated member causes constriction of the encircling portion. 10. The helmet of claim 8, wherein the elongated member completely encircles the head of the wearer when the helmet is being worn. 11. The helmet of claim 8, wherein the elongated member is attached to at least the left temporal floating pad and the right temporal floating pad. 12. The helmet of claim 8, wherein the elongated member is attached to the interior shell surface. 13. The helmet of claim 9, further comprising an adjustor having one of a dial, a bar, and a clamp operatively connected to the elongated member for causing constriction of the elongated member. 14. The helmet of claim 13, wherein the elongated member is further operatively connected with the occipital pad and constriction of the encircling portion further includes the occipital pad moving from a third position to a fourth position to assist in causing the liner to conform to the head of the wearer. 15. The helmet of claim 14, wherein the adjustor is connected to at least the occipital pad. 16. The helmet of claim 8, wherein the elongated member is further operatively connected with the occipital pad and constriction of the encircling portion further includes the occipital pad moving from a third position to a fourth position to assist in causing the liner to conform to the head of the wearer. 17.
