Abstract

A leg restraint system for a side facing seat provided in an aircraft or other conveyance. The system includes a leg restraining device including a panel configured to deploy along a deployment path when a sensed condition is met, a sensor configured to monitor the deployment path, and an indicator configured to indicate information regarding the monitored deployment path. A controller communicatively coupled to the sensor and indicator receives information and instructs the indicator to indicate a compliance status of the leg restraining device. In embodiments, an object positioned in the deployment path of the leg restraining device causes a noncompliant status to be indicated to a seated occupant thereby causing corrective action to be taken such that the leg restraining device can be operated as intended.

First claim

What is claimed:

1. A leg restraint system for a side facing seat, comprising:
a leg restraining device configured to be positioned in proximity to a side facing seat, the leg restraining device including a panel configured to deploy along a deployment path;
a sensor configured to be positioned relative to the leg restraining device, the sensor configured to monitor the deployment path;
an indicator configured to indicate information regarding the monitored deployment path; and
a controller, communicatively coupled to each of the sensor and the indicator, the controller configured to:
receive, from the sensor, information regarding the monitored deployment path; and
instruct the indicator to indicate a compliance status associated with the monitored deployment path.

2. The leg restraint system according to claim 1 , wherein:
the information regarding the monitored deployment path includes object detection information; and
the controller is further configured to instruct the indicator to indicate the compliance status of noncompliant when an object is detected in the deployment path.

3. The leg restraint system according to claim 2 , wherein the compliance status of noncompliant is conveyed by at least one of a visual indicator and an audible indicator.

4. The leg restraint system according to claim 3 , wherein the visual indicator is configured to be visible to an occupant seated in the side facing passenger seat.

5. The leg restraint system according to claim 3 , wherein the visual indicator is implemented as a beam of light projected to coincide with the deployment path.

6. The leg restraint system according to claim 1 , wherein:
the information regarding the monitored deployment path includes object detection information; and
the controller is further configured to instruct the indicator to indicate the compliance status of compliant when no object is detected in the deployment path.

7. The leg restraint system according to claim 6 , wherein the compliance status of compliant is conveyed by at least one of a visual indicator and an audible indicator.

8. The leg restraint system according to claim 7 , wherein the visual indicator is visible to an occupant seated in the side facing passenger seat.

9. The leg restraint system according to claim 7 , wherein the visual indicator is implemented as a beam of light projected to coincide with the deployment path.

10. The leg restraint system according to claim 1 , wherein:
the side facing seat is provided in an aircraft;
the controller is further configured to activate the leg restraint system during taxi, takeoff, and landing of the aircraft; and
the controller is further configured to deactivate the leg restraint system in an operating state of the aircraft other than during taxi, takeoff, and landing of the aircraft.

11. An aircraft, comprising:
a cabin;
a side facing seat positioned in the cabin; and
a leg restraint system associated with the side facing seat, the leg restraint system comprising:
a leg restraining device configured to be positioned in proximity to the side facing seat, the leg restraining device including a panel configured to deploy along a deployment path;
a sensor configured to be positioned relative to the leg restraining device, the sensor configured to monitor the deployment path;
an indicator configured to indicate information regarding the monitored deployment path; and
a controller, communicatively coupled to each of the sensor and the indicator, the controller configured to:
receive, from the sensor, information regarding the monitored deployment path; and
instruct the indicator to indicate a compliance status associated with the monitored deployment path.

12. The aircraft according to claim 11 , wherein:
the information regarding the monitored deployment path includes object detection information; and
the controller is further configured to instruct the indicator to indicate the compliance status of noncompliant when an object is detected in the deployment path.

13. The aircraft according to claim 12 , wherein the compliance status of noncompliant is conveyed by at least one of a visual indicator and an audible indicator.

14. The aircraft according to claim 13 , wherein the visual indicator is configured to be visible to an occupant seated in the side facing passenger seat.

15. The aircraft according to claim 13 , wherein the visual indicator is implemented as a beam of light projected to coincide with the deployment path.

16. The aircraft according to claim 11 , wherein:
the information regarding the monitored deployment path includes object detection information; and
the controller is further configured to instruct the indicator to indicate the compliance status of compliant when no object is detected in the deployment path.

17. The aircraft according to claim 16 , wherein the compliance status of compliant is conveyed by at least one of a visual indicator and an audible indicator.

18. The aircraft according to claim 17 , wherein the visual indicator is configured to be visible to an occupant seated in the side facing passenger seat.

19. The aircraft according to claim 17 , wherein the visual indicator is implemented as a beam of light projected to coincide with the deployment path.

20. The aircraft according to claim 11 , wherein:
the controller is further configured to activate the leg restraint system during taxi, takeoff, and landing of the aircraft; and
the controller is further configured to deactivate the leg restraint system in an operating state of the aircraft other than during taxi, takeoff, and landing of the aircraft.
