Where do Head Impact Protection Systems (HIPS) deploy from?

Head Impact Protection Systems (HIPS) are designed to enhance occupant safety in the event of a collision, particularly focusing on head injuries by providing a cushioning effect. These systems deploy from a narrow opening between the headliner and the top of the door frame, which allows the airbags to extend outwards when triggered. This positioning is specifically designed to protect the head area during a side impact collision, as the airbag deploys to create a barrier that absorbs some of the impact energy.

By deploying from this location, the system can effectively cushion the head from making contact with hard surfaces in the vehicle, reducing the risk of serious injuries. This deployment method capitalizes on the space between the door frame and headliner, strategically placing the airbag where it is most needed for occupant protection. The design ensures that the system remains unobtrusive during normal operation, only activating in the event of a crash.

In contrast, other choices do not accurately reflect the intended operational functionality and placement of HIPS. For instance, deploying from the dashboard, front seats, or side windows would not provide the same level of protection and could undermine the overall safety objectives of the design.
