(20) In an aspect of an embodiment of the present invention, seatbelt safety release device 10 may also include a small Integrated circuit 40 as shown in FIG. 8. Integrated circuit 40 may include one or more processor(s) (not shown) which would be responsible for the implementation and control of the operations of seatbelt safety release device 10. In an aspect of an embodiment of the present invention, the processor of integrated circuit 40 may be programed to work with a system of collision detection sensors 20 located throughout the vehicle. In an aspect of an embodiment of the present invention, sensors 20 may operate with a dedicated integrated circuit located within diagnostic module 22 which may be in communication with the transmitter(s) of diagnostic module 22. In another aspect of an embodiment of the present invention, the transmitter(s) of diagnostic module 22 may be wirelessly connected to integrated circuit 40. Collision sensors 20 are configured to send a signal to transmitter 50 of diagnostic module 22 when a collision is detected (FIG. 9). In another aspect of an embodiment of the present invention, sensor(s) 20 may directly send a signal, indicating a collision, to integrated circuit 40.

(21) Integrated circuit 40 may also be in communication with manual push button 42, another element of seatbelt safety release device 10. In an aspect of an embodiment of the present invention, integrated circuit 40 may also include signal receiver 48 which may be in communication with transmitter 50 for receiving signals sent from diagnostic module 22 (or directly from collision sensor(s) 20) upon collision. In an aspect of an embodiment of the present invention, integrated circuit 40 may be configured to drive or trigger servo motor 46 which then moves latch 36 (of seatbelt locking mechanism 16) which frees seatbelt safety release device tongue 38. The user is then released from the seatbelt and is able to exit the vehicle. In another aspect of an embodiment of the present invention, servo motor 46 may be used to move latch 36 onto seatbelt safety release device tongue 38 when a user first deploys seatbelt safety release device 10 upon entering the vehicle.

(22) In an aspect of an embodiment of the present invention, seatbelt safety release device 10 may be fitted over the normal buckle latch of a vehicle's seatbelt system as shown in FIG. 6. A removable panel will be there for if it needs to be placed; seatbelt safety release device 10 may be secured as a permanent replacement (until such time as it is built into vehicles as stock parts).

(23) In an aspect of an embodiment of the present invention, transmitter 50, upon receipt of signal(s) from collision sensor(s) 20, sends a signal to receiver 48. Signal receiver 48 then notifies integrated circuit 40 to trigger servo motor 40 to release the latch 36 of seatbelt locking mechanism 16 from the seat belt tongue 14.

(24) In another aspect of an embodiment of the present invention, tongue 38 of seatbelt safety release device 10 may be disengaged from seatbelt locking bay 12 when the collision signal is received by integrated circuit 40. In yet another aspect, both tongue 38 and latch 36 of seatbelt safety release device 10 may be disengaged from seat belt tongue 14 and seatbelt locking bay 12 when a collision signal is received by integrated circuit 40.

(25) In another aspect of an embodiment of the present invention, seatbelt safety release device 10 may have a built in time delay to make sure the seatbelt does its job, then when the delay is over the seatbelt will be released. Manual release button 42 is there to tell the motor to release the latch on the seat belt; it will work just like it normally does.

(26) Operation of integrated circuit 40 (and thus release of the seatbelt) may be based on two Inputsone from manual pushbutton 42 (whereby a user manually depresses pushbutton 42 which triggers a signal to servo motor 46 to release latch 36), and the other from receiver 48, which notifies integrated circuit 40 of a collision. With this system in place it can be all the seatbelts in the car can have a Q Release on them, and the transmitters will send the signal to all the receivers so all will work at the same time.

(27) Referring now to FIG. 10 a control diagram for seatbelt safety release device 10 is shown according to an aspect of an embodiment of the present invention. Here, integrated circuit or control unit 40 may receive a signal input signifying a collision or impact from either of push button 42 or sensor(s) 20. This may also occur in a case of non-impact where the driver or user my just want to exit the vehicle and depresses push button 42. The signal would activate control unit 40 to trigger servo motor 46 to activate seatbelt locking mechanism 16 to move latch 36, thereby unlocking or uncoupling latch 36 from seatbelt tongue 14. Seatbelt locking mechanism 16 may also be activated by servo motor 46 to unlock seatbelt safety release tongue 38 from seatbelt locking bay 12. In another aspect of an embodiment of the present invention where adapter piece 32 is used, the signal would activate control unit 40 to trigger servo motor 46 to activate seatbelt locking mechanism 16 to move latch 36, thereby unlocking or uncoupling latch 36 from adapter piece 32.

(28) In an aspect of an embodiment of the present invention, the control unit may be configured to delay activation of servo motor 46 upon receipt of a signal from sensor(s) 20. In one aspect of an embodiment of the present invention, this delay may be 10-15 seconds. The delay times may be programmed into the chip or control unit 40.
