Abstract

A passenger seat for a vehicle includes a head restraint positioned at an upper portion of the passenger seat and a lateral head support selectively configurable between a deployed configuration in which the lateral head support provides lateral support for at least one side of a passenger head and a stowed configuration in which the lateral support collapses into the passenger seat such that the lateral head support no longer provides lateral support for a passenger head.

First claim

What is claimed is:

1. A passenger seat for a vehicle comprising:
an upper portion of a seat back of the passenger seat; and
a lateral head support selectively configurable between a deployed configuration in which the lateral head support provides lateral support for at least one side of a passenger head and a stowed configuration in which the lateral support collapses into the passenger seat such that the lateral head support no longer provides lateral support for a passenger head, wherein the lateral head support comprises a flexible fabric.

2. The passenger seat of claim 1 , wherein the upper portion of the seat back comprises a head restraint.

3. The seat of claim 1 , further comprising a shoulder harness and wherein the lateral head support is attached to one of the shoulder harness and the upper portion of the seat back and wherein the lateral head support is selectively fastenable to the other of the shoulder harness and the upper portion of the seat back.

4. The seat of claim 3 , wherein the lateral head support comprises a hook shaped fastener for selectively fastening to the other of the shoulder harness and the upper portion of the seat back.

5. The seat of claim 1 , further comprising a flexible rod attached at a distal end to an edge of the flexible fabric and at a proximal end to one of the shoulder harness and the upper portion of the seat back.

6. The seat of claim 1 , wherein the flexible fabric includes a top section that connects between two opposing sides of the lateral head support.

7. The seat of claim 1 , the lateral head support further comprises a rope-like support connected to the flexible fabric.

8. The seat of claim 7 , wherein the rope-like support is adjustable in length to adapt the shape of the flexible fabric to a passenger head.

9. The seat of claim 1 , wherein the lateral head support further comprises a retractable support arm that is attached to an edge of the flexible fabric and wherein the upper portion of the seat back comprises a winding mechanism operable to selectively extend the support arm from the upper portion of the seat back and to retract the support arm into the upper portion of the seat back.

10. A passenger seat for a vehicle comprising:
an upper portion of a seat back of the passenger seat; and
a lateral head support selectively configurable between a deployed configuration in which the lateral head support provides lateral support for at least one side of a passenger head and a stowed configuration in which the lateral support collapses into the passenger seat such that the lateral head support no longer provides lateral support for a passenger head, wherein the lateral head support is attached to the upper portion of the seat back and comprises a fan folded fabric.

11. The seat of claim 1 , wherein the head restraint comprises a first engagement member on an upper portion of the upper portion of the seat back and a second engagement member on a lower portion of the upper portion of the seat back.

12. The seat of claim 11 , wherein the lateral head support further comprises a fastener which is selectively engageable with the first engagement member to place the lateral head support in a deployed configuration and a second engagement member to place the lateral head support in a stowed configuration.

13. A passenger seat for a vehicle comprising:
an upper portion of a seat back of the passenger seat; and
a lateral head support selectively configurable between a deployed configuration in which the lateral head support provides lateral support for at least one side of a passenger head and a stowed configuration in which the lateral support collapses into the passenger seat such that the lateral head support no longer provides lateral support for a passenger head, wherein the lateral head support comprises an outer facing panel that is connected to a surface of the upper portion of the seat back by at least one flexible rib.

14. The seat of claim 13 , wherein the lateral head support further comprises:
a fastener on the outer facing panel;
a first set of connectors on a surface of the upper portion of the seat back adapted to engage the fastener in a deployed configuration in which the outer facing panel is spaced away from the surface of the upper portion of the seat back; and
a second set of connectors on the surface of the head restraint adapted to engage the fastener in a stowed configuration in which the outer facing panel is spaced closer to the surface of the upper portion of the seat back than in the deployed configuration.

15. The seat of claim 1 , wherein the lateral head support comprises a bi-stable flexible rod that is stable in both a deployed configuration in which the bi-stable flexible rod is positioned forward of the upper portion of the seat back of the seat and in an intermediate configuration in which the bi-stable flexible rod is positioned to the rear of the upper portion of the seat back.

16. The seat of claim 15 , wherein the lateral head support further comprises a support post fastener that connects the bi-stable flexible rod to a head restraint support post of the upper portion of the seat back.

17. The seat of claim 15 , wherein the flexible fabric extends between extended portions of the bi-stable flexible rod.

18. The seat of claim 15 , wherein the lateral head support further comprises a plurality of clip fasteners on a rear facing surface of the upper portion of the seat back which are each adapted to engage with the bi-stable flexible rod in the stowed configuration.
