Retractable Face Shield for Bike Helmets
Detachable, retractable (it goes up to the top of the regular bike helmet or down in front of your face) face shield much like the face shields worn by police officers wearing riot gear masks but, with much lighter weight (thin but, strong clear plastic). Not for impact protection but, has many other protective features such as pebbles, bugs, wind burn, dirt, dust, or other flying debrise protecting all parts of your face especially your eyes from abrasion from objects in the air (dust can scratch your eyes and mess with your breathing). It would sit on top of your head and helmet, when not in use, completely out of the way and would not alter the existing design of bike helmets of today. You could even un-snap it and take it off completely returning your helmet back to original design. What we are trying to avoid with this design is adding weight or obscuring vision and by making the mask limited in size and only in front of the face we solve both these problems especially since plastic can be strong, durable, replaceable, and light in weight. Cheap to make and cheap to buy and a very easy thing to add to existing helmet designs.
