The backpack can be converted into an airbag for cyclists to protect them from injuries

Helmets should be worn by cyclists while they are riding their bicycles through the city. The helmet may protect the brain from severe injury, but other parts of the head and body are vulnerable to minor or serious injuries if they come into contact with other vehicles or pedestrians. If there was a portable airbag that could protect them in the event of an accident, it would be great.
