| 摘要 |
This invention relates to a new class of the design of mechanical crash-detecting sensors. A sensing mass (65, 14, 84) is biased by a spring (63), a diaphragm (13) or one or more cantilever beams (81) with a relatively high biasing force. Air damping is provided by inertial or viscous flow caused by the travel of the sensing mass. The travel of the sensing mass to trigger in this invention is typically 0.05 inch, which is much shorter than those of conventional mechanical crush-zone sensors. This invention also provides a new to increase the duration of contact closure once a sensor (10) has triggered. These improvements can enhance the effectiveness of mechanical sensors, and thus provide a simple reliable sensing device for activating occupant restraint systems. |
