An apparatus for preventing occupant injury during accident has various features to ensure safety. A sensor 70 , detecting seat belt engagement is provided. In addition, there is a means for varying the tension of a seatbelt 17 , depending upon the weight of the occupant 110 and the speed of the vehicle carrying the occupant 110 . When the occupant 110 seats on any of the seats 17 , the load cell switch 18 will close, allowing the load cell output energy to energize the control module 25 . The control module 25 will then enables the counter 50 to count the number of closed load cell switches 18 . The control module 25 further enables an optoisolator switch configured with the sensor 70 to then energize a latching relay 80 operatively configured to check the seat belt latching of all occupied seats 10 with closed load cell switches 18 , to assure occupants safety. The load cells are configured with strain gauges and temperature sensors to ensure human occupants. Such that, when the switch 18 for the occupied seat 10 is closed, the latching relay 80 circuit is energized so that the seat belt 17 for the occupied seat location is checked for buckling. The latching relay 80 circuit and the counter 50 circuit are operatively configured and closed only when an occupant 110 takes any of the seats 10 . The latching relay switch 85 is only energized when the counter circuit 50 is closed.
