Uncontrolled mechanical oscillations transmitted through the vehicle seat cause physical fatigue and reduced safety. Mitigating these vibrations improves structural stability and occupant protection during transit.

Inaccurate detection of occupant presence or seat belt status leads to improper deployment of safety systems. Precise usage determination prevents unnecessary deployment or failure to protect during collisions.

Inertial movement of occupants during collisions leads to secondary impact injuries. Reducing free volume and slack minimizes kinetic energy transfer to the passenger.
