摘要

According to a study from Insurance Institute for Highway Safety (IIHS), knee airbags have a negligible effect on injury risk and may even increase that risk in some cases. Typically deployed from the lower dashboard, knee airbags are intended to reduce leg injuries by distributing impact forces and may help reduce forces on an occupant's chest and abdomen by controlling lower body movement.IIHS researchers examined crash-test data and real-world crash reports to find out if knee airbags improve safety. For the first part, they looked at injury measures from more than 400 frontal crash tests to learn whether injuries were less likely when vehicles were equipped with knee airbags. To look at real-world outcomes, they compiled crash reports from 14 states and compared injury risk in vehicles with and without knee airbags.
