The safety belt release mechanism includes sensor and belt release components. The sensor is installed at a low point within the vehicle. The sensor contains water-soluble material that retains a spring in compression so long as the water-soluble material is dry. If the vehicle is immersed in water, the water-soluble material dissolves, releasing the spring. In one embodiment, the spring drives a pin into a pressurized gas (e.g., CO2) cartridge, releasing the gas therein. The gas passes through a tube to the belt release component installed upon a belt latch mechanism, driving a pin from an engaged position in the latch to release the latch. In another embodiment, the spring acts directly to drive the latch pin from the engaged position to release the latch. While one such assembly is disclosed herein, it is most preferred that one such assembly be installed along each safety belt assembly of the vehicle. |
