Abstract

An airbag control assembly for an adjustable vehicle seat in a vehicle may include electrical wiring and an airbag mechanism. The electrical wiring may be configured to transmit electricity from a vehicle power supply of the vehicle to an airbag. The airbag mechanism may be configured to cause enabling and disabling of the airbag. The airbag mechanism may be configured to cause enabling of the airbag if the seat is in a usable position and may be configured to cause disabling of the airbag if the seat is in an unusable position.

Claims

1. An airbag control assembly for an adjustable vehicle seat in a vehicle, comprising:

electrical wiring configured to transmit electricity from a vehicle power supply of the vehicle to an airbag; and

an airbag mechanism configured to cause enabling and disabling of the airbag,

wherein the airbag mechanism is configured to cause enabling of the airbag if the seat is in a usable position,

wherein the airbag mechanism is configured to cause disabling of the airbag if the seat is in an unusable position.

2. The airbag control assembly of claim 1, wherein the airbag mechanism is a switch that allows electricity to flow to the airbag in the usable position and prevents electricity from flowing to the airbag in the unusable position.

3. The airbag control assembly of claim 1, wherein the airbag mechanism is a position sensor that causes a processor to enable or disable to the airbag.

4. The airbag control assembly of claim 3, wherein the position sensor detects a current position of the seat and whether or not the seat is locked.

5. The airbag control assembly of claim 1, wherein the usable position is when a seat back of the seat is at least partially reclined or upright, the seat is locked to a floor of a vehicle, and the seat back and a seat cushion are locked.

6. The airbag control assembly of claim 1, wherein the unusable position is when at least a portion of the seat is at least one of at least partially collapsed, at least partially folded, at least partially stowed, unattached from a floor of the vehicle, or unlocked.

7. The airbag control assembly of claim 1, wherein the electrical wiring includes seat electrical wiring to connect the airbag mechanism to vehicle electrical wiring through an electrical connector.

8. The airbag control assembly of claim 1, wherein the airbag mechanism is located on or within the seat.

9. The airbag control assembly of claim 1, wherein the airbag is located within the seat.

10. The airbag control assembly of claim 1, wherein the airbag is located on a body of the vehicle near the seat such that the airbag is configured to protect an occupant within the seat.

11. A method of controlling an airbag for a vehicle seat in a vehicle comprising:

detecting whether the seat is locked and a current position of the seat;

enabling the airbag if the seat is in a usable position; and

disabling the airbag if the seat is in an unusable position.

12. The method of claim 11, further comprising providing a switch that allows electricity to flow from the vehicle to the airbag in the usable position and prevents electricity from flowing to the airbag in the unusable position.

13. The method of claim 11, further comprising providing a position sensor that causes a processor to enable or disable the airbag.

14. The method of claim 11, further comprising transmitting a signal from a vehicle processor to an airbag mechanism when a vehicle accident has been detected and deploying the airbag if the seat is in the usable position.
