Displaceable airbag cushion safety systems and related methods
Apparatus, methods, and systems for repositioning an airbag cushion prior to and/or during deployment of the airbag cushion resulting from an impact event. Some embodiments may comprise one or more sensors, which may be used to detect at least a first directional component of an impact with a vehicle. A steering wheel actuator may be provided to move a vehicle steering wheel laterally in a direction opposite from a lateral component of the impact in response to a signal from the one or more sensors. The system may further comprise an airbag cushion configured to be positioned, following deployment, in a location corresponding with lateral movement caused by the steering wheel actuator.
1. A vehicle safety system, comprising:
a first sensor configured to detect at least a first directional component of an impact with a vehicle;
a steering wheel actuator configured to move a vehicle steering wheel laterally in a direction opposite from a lateral directional component of the impact in response to a signal from at least the first sensor; and
an airbag cushion configured to be positioned, following deployment, in a location corresponding with the lateral movement caused by the steering wheel actuator.
2. The vehicle safety system of claim 1 , wherein the first sensor comprises an accelerometer.
3. The vehicle safety system of claim 1 , further comprising a second sensor configured to detect a second directional component of the impact with the vehicle.
4. The vehicle safety system of claim 3 , wherein the first sensor is oriented at a first angle, and wherein the second sensor is oriented at a second angle offset from the first angle.
5. The vehicle safety system of claim 4 , wherein the first angle is offset from the second angle by about 90 degrees.
6. The vehicle safety system of claim 1 , wherein the steering wheel actuator is further configured to tilt the vehicle steering wheel in response to the signal from at least the first sensor.
7. The vehicle safety system of claim 6 , wherein the steering wheel actuator is further configured to tilt the vehicle steering wheel laterally in a direction corresponding with the direction of the impact in response to the signal from at least the first sensor.
8. A vehicle, comprising:
a steering wheel;
an airbag cushion configured to deploy in a location corresponding with a location of the steering wheel; and
a vehicle safety system, comprising:
a sensor configured to detect an impact with the vehicle;
a steering wheel actuator configured to move the steering wheel laterally in response to detection of the impact; and
an airbag cushion configured to be positioned, following deployment, in a location corresponding with lateral movement caused by the steering wheel actuator.
9. The vehicle of claim 8 , wherein the sensor is configured to determine an angle of the impact.
10. The vehicle of claim 8 , further comprising a vehicle computer system, wherein the vehicle computer system is configured to receive a signal from the sensor and, upon detecting a predetermined characteristic of the impact, transmit a signal to the steering wheel actuator to move the vehicle steering wheel laterally.
11. The vehicle of claim 10 , wherein the predetermined characteristic of the impact comprises a threshold lateral component of the impact event.
12. The vehicle of claim 10 , wherein the vehicle computer system is further configured to calculate a desired lateral movement distance for the steering wheel, and wherein the steering wheel actuator is configured to move the steering wheel laterally in response to detection of the impact by a distance corresponding to the desired lateral movement distance.
13. The vehicle of claim 8 , wherein the steering wheel actuator is configured to move the steering wheel in a direction opposite from a lateral component direction of the impact.
