Abstract

Various implementations include a system for adjusting the position of a seatbelt in a vehicle. The system includes a shoulder anchor, at least one sensor, and a processor. The shoulder anchor is for receiving a seatbelt. The shoulder anchor is movable relative to a seat disposed within the vehicle. The processor is in electrical communication with the sensor and a memory. The processor executes computer-readable instructions stored on the memory. The instructions cause the processor to receive sensor data from the sensor, determine whether the seatbelt is within an expected area on a person in the seat based on the received sensor data, and cause the shoulder anchor to move relative to the seat in response to the seatbelt being outside of the expected area on the person in the seat such that the seatbelt is moved into the expected area.

First claim

What is claimed is:

1. A system for adjusting a position of a seatbelt in a vehicle, the system comprising:
a retractor mounted in a fixed position within a seat, the retractor configured to spool and unspool a webbing of the seatbelt;
a shoulder anchor including a D-ring configured to receive the webbing and to be disposed within a seat back of the seat adjacent to and aligned with a slit formed in a seat cover through which the webbing extends;
a drive system configured to be positioned within the seat, the drive system coupled to and moving the shoulder anchor between a first position within the seat back and a second position within the seat back, wherein the first position is closer than the second position to a seat base of the seat;
at least one sensor; and
a processor in electrical communication with the at least one sensor and a memory, wherein the processor executes computer-readable instructions stored on the memory, the instructions causing the processor to:
receive sensor data from the at least one sensor,
determine whether the seatbelt is within an expected area on a person in the seat based on the received sensor data, and
control operation of the drive system to move the shoulder anchor relative to the seat in response to the seatbelt being outside of the expected area on the person in the seat such that the seatbelt is moved into the expected area.

2. The system of claim 1 , wherein the drive system includes a two-axis servo motor for moving the shoulder anchor relative to the seat in two degrees of movement.

3. The system of claim 2 , wherein the two-axis servo motor is disposed within the seat back.

4. The system of claim 1 , wherein the shoulder anchor is rotationally movable relative to the seat.

5. The system of claim 1 , wherein the at least one sensor comprises an imaging unit.

6. The system of claim 5 , wherein the imaging unit comprises a camera or a motion detector.

7. The system of claim 1 , wherein the sensor data comprises an image and the processor determines the expected area of the seatbelt on the person based on;
a height of the person in the image relative to the seat;
an orientation of the person in the image relative to the seat; or
a gesture performed by the person in the image.

8. The system of claim 1 , wherein the sensor data includes information corresponding to:
an angle of the seat back of the seat relative to the seat base of the seat;
a detection of movement of the person in response to a previous movement of the shoulder anchor;
a detection of movement of the person over a period of time; or
a detection of a pre-crash condition of the vehicle.

9. The system of claim 1 , wherein the drive system includes a linear actuator for moving the shoulder anchor relative to the seat.

10. The system of claim 9 , wherein the linear actuator is disposed within the seat back.

11. The system of claim 1 , wherein movement of the shoulder anchor relative to the seat causes a change in the position and angle of the webbing relative to the seat when the webbing is in a buckled position.

12. An automotive seat comprising:
a seat frame;
a retractor rigidly coupled to the seat frame and positioned within the automotive seat;
a shoulder anchor defining a D-ring opening, the shoulder anchor positioned within the automotive seat;
a drive system coupled between the seat frame and the shoulder anchor, the drive system positioned within the automotive seat and configured to move the shoulder anchor between a first position and a second position relative to the seat frame;
a webbing coupled to the retractor, passing through the D-ring opening, and passing through a slit formed in the automotive seat;
at least one sensor; and
a processor in electrical communication with the at least one sensor and a memory, wherein the processor executes computer-readable instructions stored on the memory, the instructions causing the processor to:
receive sensor data from the at least one sensor,
determine whether the webbing is within an expected area on a person in the automotive seat based on the received sensor data, and
control operation of the drive system to move the shoulder anchor relative to the seat frame in response to the webbing being outside of the expected area on the person in the automotive seat such that the webbing is moved into the expected area.

13. The automotive seat of claim 12 , wherein the drive system includes a two-axis servo motor for moving the shoulder anchor relative to the seat frame in two degrees of movement.

14. The automotive seat of claim 12 , wherein the drive system includes a linear actuator for moving the shoulder anchor relative to the seat.

15. The automotive seat of claim 12 , wherein the sensor data comprises an image and the processor determines the expected area of the webbing on the person based on:
a height of the person in the image relative to the automotive seat;
an orientation of the person in the image relative to the automotive seat; or
a gesture performed by the person in the image.

16. The automotive seat of claim 12 , wherein the sensor data includes information corresponding to:
an angle of a seat back of the automotive seat relative to a seat base of the automotive seat;
a detection of movement of the person in response to a previous movement of the shoulder anchor;
a detection of movement of the person over a period of time; or
a detection of a pre-crash condition.

17. An automotive seat comprising:
a seat base;
a seat back coupled to the seat base and defining a slit;
a retractor positioned within the seat back in a fixed position;
a linear actuator positioned within the seat back;
a motor positioned within the seat back and coupled to the linear actuator;
a shoulder anchor positioned within the seat back and defining a D-ring opening, the shoulder anchor coupled to the motor;
a webbing coupled to the retractor, passing through the D-ring opening, and passing through the slit; and
a processor in electrical communication with at least one sensor and a memory, wherein the processor executes computer-readable instructions stored on the memory, the instructions causing the processor to control operation of the linear actuator and the motor to move the shoulder anchor within the seat back in response to the webbing being outside of an expected area.

18. The automotive seat of claim 17 , wherein the motor includes a two-axis servo motor for moving the shoulder anchor relative to the seat back in two degrees of movement.

19. The automotive seat of claim 17 , further comprising an imaging unit configured to provide image data,
wherein the processor further executes instructions causing the processor to receive the image data and determine the webbing is outside the expected area based on the image data.

20. The automotive seat of claim 19 , wherein the processor further executes instructions causing the processor to control the linear actuator and the motor to move the shoulder anchor into the expected area.
