Abstract

Various systems and methods are presented regarding automatically controlling a position of a seat belt located onboard a vehicle, wherein the position is controlled in accordance with physiology of an occupant utilizing the seat belt. By adjusting the position of the seat belt in accordance with the occupant's physiology, the seat belt system can be configured to improve operation of the seat belt in restraining the occupant during vehicle deceleration. Position of the seat belt can be controlled by a guidance device comprising a positionable guide pin which changes alignment of the seatbelt. A motor can be utilized to control positioning of the pin, wherein the motor can be controlled by a system configured to receive data from one or more sensors regarding any of the occupant's physiology, operation of the seat belt, position of the pin, and suchlike.

determines, using the at least one sensor of the vehicle, a position of the seat belt webbing relative to the physiology of the occupant; and

controls the motor to adjust the guide pin to a first position on the first axis that adjusts the seat belt webbing to a second position on the second axis based on the physiology of the occupant to create a defined distance between a portion of the edge of the seat belt and a portion of a neck of the occupant.

2. The vehicle of claim 1 , wherein the at least one of the computer executable components further:

based on the physiology of the occupant, generates a position instruction to adjust the guide pin to the first position; and

transmits the position instruction to the webbing guide device, wherein the webbing guide device is configured to adjust positioning of the guide pin in response to the position instruction.

3. The vehicle of claim 1 , wherein the at least one sensor comprises at least one of a camera or a radar device.

4. The vehicle of claim 1 , wherein the at least one of the computer executable components further:

determines, using the at least one sensor, a position of the portion of the edge of the seat belt webbing relative to the portion of the neck of the occupant.

5. The vehicle of claim 1 , wherein the at least one of the computer executable components further:

receives, from a sensor of the at least one sensor, seat belt fasten data, the seat belt fasten data indicates whether a tongue located on the seat belt is inserted in a seat belt buckle utilized to secure the seat belt, wherein the sensor is located in the seat belt buckle.

6. The vehicle of claim 5 , wherein the at least one of the computer executable components further:

in response to a determination that the seat belt fasten data indicates the tongue is released from the seat belt buckle, transmit a position instruction to the webbing guide device, wherein the position instruction controls the webbing guide device to return the guide pin to an initial position on the first axis, wherein the initial position places the seat belt webbing in a position on the second axis to enable the seat to be lowered.

7. The vehicle of claim 6 , wherein the at least one of the computer executable components further:

in response to a determination that the seat belt fasten data indicates the tongue is released from the seat belt buckle, cease at least one of the determining the physiology of the occupant or positioning of the seat belt webbing.

8. The vehicle of claim 1 , wherein the seat belt is part of a three-point seat belt system.

9. A computer-implemented method comprising:

determining, by a system comprising a processor located on a vehicle, using at least one sensor of the vehicle, physiology of an occupant located in a seat of the vehicle, wherein the vehicle comprises:

a webbing guide device comprising a guide pin that is adjustable along a first axis by a motor of the webbing guide device, and

a seat belt comprising a seat belt webbing, wherein an edge of the seat belt webbing abuts the guide pin when the seat belt is worn by the occupant in the seat of the vehicle, wherein movement of the guide pin along the first axis moves a portion of the seat belt webbing comprising the edge of the seat belt webbing that abuts the guide pin along a second axis that is substantially horizontal, and wherein the first axis is different from the second axis;

determining, by the system, using the at least one sensor, a position of the seat belt webbing relative to the physiology of the occupant; and

controlling, by the system, the motor to adjust the guide pin to a first position on the first axis that adjusts the seat belt webbing to a second position on the second axis based on the physiology of the occupant to create a defined distance between a portion of the edge of the seat belt and a portion of a neck of the occupant.

10. The computer-implemented method of claim 9 , further comprising:

based on the physiology of the occupant, generating, by the system, a position instruction to adjust the guide pin to the first position; and

transmitting, by the system, the position instruction to the webbing guide device, wherein the webbing guide device is configured to adjust positioning of the guide pin in response to the position instruction.

11. The computer-implemented method of claim 9 , wherein the at least one sensor comprises at least one of a camera or a radar device.

12. The computer-implemented method of claim 9 , further comprising:

determining, by the system, using the at least one sensor, a position of the portion of the edge of the seat belt webbing relative to the portion of the neck of the occupant.

13. The computer-implemented method of claim 9 , further comprising:

receiving, by the system, from a sensor of the at least one sensor, seat belt fasten data, the seat belt fasten data indicates whether a tongue located on the seat belt is inserted in a seat belt buckle utilized to secure the seat belt, wherein the sensor is located in the seat belt buckle.

14. The computer-implemented method of claim 13 , further comprising:

in response to determining that the seat belt fasten data indicates the tongue is released from the seat belt buckle, transmitting, by the system, a position instruction to the webbing guide device, wherein the position instruction controls the webbing guide device to return the guide pin to an initial position on the first axis, wherein the initial position places the seat belt webbing in a position on the second axis to enable the seat to be lowered; and
