ABSTRACT:
This invention includes crash sensors designed to be used for frontal impact sensing and the strategies of using these sensors. It is analyzed and shown that for cases where the passenger compartment mounted discriminating sensor is used as a backup to forward crush zone mounted crash sensors or where the vehicle occupant is wearing a seat belt, that spring mass sensors can be used. In addition, spring mass sensors can also be used as arming or safing sensors. In all cases, provision must be made to minimize the effects of cross-axis vibrations on such sensors as taught by this invention. Such sensors can be made with housings of plastic. A preferred embodiment of this invention utilizes a mass supported and biased by a beam contact which is attached to a housing. These sensors are useful for sensing frontal impacts in the passenger compartment both as primary sensors and as single or dual contact arming sensors. They can also be combined by placing two sensors within a single housing and, in some cases, the same mass can be used for both sensors. Finally, they can be used in electro-mechanical and in all mechanical air bag systems. It is further taught that the response of all spring biased sensors can be improved by making the at rest bias substantially less than the bias at actuation.
