Side airbags are safety devices installed in vehicles to protect occupants during side-impact collisions. They deploy from the side of the vehicle, typically from the seat or the door, to cushion and shield passengers from injury. These airbags help reduce the risk of serious injuries to the head and torso by creating a barrier between the occupants and the vehicle's interior or other objects. In addition to side airbags, many modern vehicles also feature curtain airbags, which extend down from the roof to protect passengers in the event of a rollover or side crash. Together, these safety features enhance overall vehicle protection and contribute to safer driving experiences.
