Abstract
A vehicle seat is rotatable about an axis perpendicular to a vehicle floor from a forward-facing position to a rear-facing position. The seat includes a seat bottom and a seat back. A seat belt assembly extends at least partially from the seat back. At least one airbag is incorporated into the seat belt assembly and is deployable when the vehicle seat is rotated to at least one of the rear-facing position and a position between the forward-facing position and the rear-facing position.
Claims19
A system, comprising:
- a vehicle seat rotatable, about an axis perpendicular to a vehicle floor, from a forward-facing position to a rear-facing position, the seat including a seat bottom and a seat back;
- a seat belt assembly at least partially extending from the seat back;
- at least one airbag incorporated into the seat belt assembly and deployable when the vehicle seat is rotated to at least one of the rear-facing position and a position between the forward-facing position and the rear-facing position;
- and
- a processor programmed to determine a vehicle seat position and to detect a vehicle impact and to output a control signal to an inflator to inflate the at least one airbag based on the vehicle seat position about the axis.
A seatbelt assembly comprising:
- a webbing forming a shoulder strap and a belt strap;
- at least one airbag incorporated into at least one of the shoulder strap and the belt strap;
- and
- a processor programmed to determine a vehicle seat position, including a forward-facing position and a rear-facing position, wherein the processor is programmed to output a control signal in response to the vehicle seat being in at least one of the rear-facing position and a position between the forward-facing position and the rear-facing position and in response to detecting a vehicle impact, wherein the control signal causes the at least one airbag to inflate.
A system, comprising:
- a vehicle seat rotatable, about an axis perpendicular to a vehicle floor, from a forward-facing position to a rear-facing position, the seat including a seat bottom and a seat back;
- a seat belt assembly at least partially extending from the seat back including a first anchor, a second anchor, and a retractor;
- a first airbag and a second airbag incorporated into the seat belt assembly and deployable when the vehicle seat is rotated to at least one of the rear-facing position and a position between the forward-facing position and the rear-facing position;
- an inflator disposed in at least one of the seat back and the seat bottom;
- and
- a processor programmed to determine a vehicle seat position and a vehicle impact and output a control signal to the inflator in response to detecting the vehicle seat in at least one of the rear-facing position and the position between the forward-facing position and the rear-facing position and the vehicle impact;
- wherein the first and second anchors extend from the seat bottom and the retractor extends from the seat back;
- wherein the seat belt assembly includes a shoulder strap and a belt strap and wherein the first airbag is incorporated into the shoulder strap and the second airbag is incorporated into the belt strap;
- wherein the inflator is in fluid communication with at least one of the first and second airbags and configured to inflate at least one of the first and second airbags in response to receiving the control signal output by the processor.
