Abstract
An impact sensing apparatus for a motor vehicle includes a control module having an accelerometer and a contact switch mounted in a bumper of the motor vehicle. The contact switch is in an open position and is in communication with the control module. The control module deploys an airbag when the accelerometer detects a change in velocity of the motor vehicle exceeding a threshold lowered when the contact switch is urged by the bumper to a closed position.
