A pedestrian air bag device includes a housing for at least one air bag; an attachment connected to the housing for attachment to a pedestrian; the air bag(s) contained with a compressed gas chamber for release of compressed gas into and deployment of the air bag(s); and sensor(s) and release mechanism connected to the compressed gas chamber for opening it in response to the sensor(s) sensing a predetermined change in a physical characteristic, such as a predetermined change that is selected from the group consisting of an angle change of a predetermined angle, an altitude change of a predetermined altitude characteristic, or a combination thereof For example, it may be a predetermined change in an angle of at least 45 degrees. Alternatively, it could be a predetermined altitude characteristic change could be a decrease in gravitational pull or a negative difference in actual altitude measurements.
