Abstract

A lightweight, flexible, light-attenuating sun and glare shield is disclosed that is attachable via static electricity to the inside of a motorcycle helmet visor. No modification of the motorcycle helmet or visor is required for attachment of the shield, and the shield need not be specially configured for a specific model of helmet, so long as the shape and size of the shield is generally compatible with the visor. The shield is easily removed from the visor and rolled up for convenient transportation and storage. In preferred embodiments, the light attenuating shield is polarized and/or includes graduated tinting. Some embodiments include a storage canister for easy transportation and storage of the shield, and certain embodiments include a plurality of shields, which can be disposable and/or can include shields with different light attenuating properties.

Claims

1. A light attenuating shield attachable to a motorcycle helmet visor, the light attenuating shield comprising:

a flexible sheet of polymeric film,

the flexible sheet being shaped so as to conform to a portion of an inner surface of a motorcycle visor,

the flexible sheet being able to attenuate light passing through the flexible sheet, and

the flexible sheet being removably attachable to the portion of the inner surface of the motorcycle visor by static electric attraction.

2. The light attenuating shield of claim 1, wherein the flexible sheet is tinted.

3. The light attenuating shield of claim 1, wherein the flexible sheet attenuates light in a non-uniform manner across the sheet.

4. The light attenuating shield of claim 1, wherein the flexible sheet polarizes light passing therethrough.

5. The light attenuating shield of claim 4, wherein light passing through the sheet is polarized so as to provide maximum attenuation of reflected glare.

6. The light attenuating shield of claim 1, further comprising at least one additional flexible sheet of polymeric film.

7. The light attenuating shield of claim 6, wherein a light attenuation characteristic of a first flexible sheet of polymeric film is different from a light attenuation characteristic of a second flexible sheet of polymeric film.

8. The light attenuating shield of claim 6, wherein at least two flexible sheets of polymeric film can be overlaid and simultaneously attached to the inside of the helmet visor.

9. The light attenuating shield of claim 1, wherein the flexible sheet is disposable.

10. The light attenuating shield of claim 1, wherein the flexible sheet is sufficiently flexible to enable transportation and storage of the flexible sheet in a rolled configuration.

11. The light attenuating shield of claim 10, further comprising a storage canister within which the flexible sheet can be stored when the flexible sheet is in a rolled configuration.

12. The light attenuating shield of claim 10, further comprising a rod for rolling the flexible sheet into a rolled configuration.

13. The light attenuating shield of claim 12, wherein the rod includes an elongated slot into which an end of the flexible sheet can be inserted so as to facilitate rolling of the flexible sheet.
