ABSTRACT:
An interactive safety helmet for a bicyclist, making it possible for a group of bicyclists wearing like helmets to communicate with each other and thereby coordinate their activities. The helmet is formed by an outer shell shaped to fit onto the head of the bicyclist and an inner cushioning liner having a pair of miniature loud speakers embedded therein at opposing sides adjacent the ears of the bicyclist. Extending from the shell is a gooseneck supporting a microphone at a position adjacent the mouth of the bicyclist. Mounted on the shell is a miniature radio transceiver whose transmitter section is coupled to the microphone and whose receiver section is coupled to the loud speakers. The transceiver is connected by a line extending from the helmet to an external battery power pack. In operation, a bicyclist wearing the helmet can by talking into the microphone and listening to the loud speakers interact with other bicyclists in the group. The helmet is also provided on either side thereof with an LED safety flashing light powered by the same power pack.
