Which safety system includes airbags that deploy above the door frame and may or may not deflate after deployment?

• A. Head protection systems
• B. Curtain airbags
• C. Seat belts
• D. Steering wheel airbags

Answer: (A)

Curtain airbags deploy from above the door frame and extend down along the side of the window to shield the head in side impacts or rollovers. Some designs stay inflated for a period after deployment, while others deflate gradually, which is why they may or may not deflate after deployment. This placement and behavior distinguish them from steering wheel airbags (which deploy in front of the driver), seat belt systems (restraints rather than airbags), and other head-protection options that aren’t specifically the above-door-frame curtain type.
