Abstract
A vehicular crash sensing system includes a bumper cap for contacting a bumper. A chamber fits into a side rail attached to the bumper, the chamber being sealed by the bumper cap. A stop element limits movement of the chamber into the side rail. A pressure sensor detects an increased chamber air pressure during crushing of the chamber resulting from movement of the bumper with respect to the stop element.
