Abstract

An inertia reel interface for stowable seats is provided. The inertia reel interface may allow for simple access and replacement of inertia reels during maintenance. The inertia reel interface may comprise an inertia reel beam, a payout tube, and one or more inertia reels coupled to the inertia reel beam. The inertia reel beam may deploy a shoulder harness webbing over the payout tube. The payout tube may pivot to a first access position or a second access position to allow for maintenance of the inertia reel interface components.

First claim

What is claimed is:

1. A stowable seat, comprising:
a housing;
a backrest pivotally coupled to the housing, wherein the backrest is configured to pivot from a closed position into an open position; and
an inertia reel interface, comprising:
an inertia reel beam coupled at a first end to a first inner surface of the housing and at a second end to a second inner surface of the housing;
a payout tube coupled at a third end to the first inner surface of the housing and at a fourth end to the second inner surface of the housing; and
an inertia reel coupled to the inertia reel beam, wherein the inertia reel is configured to deploy a shoulder harness webbing over the payout tube and the backrest, wherein the inertia reel is coupled to the inertia reel beam with a mechanical fastener inserted through a shoulder bushing.

2. The stowable seat of claim 1 , further comprising a web separator coupled to an outer surface of the payout tube.

3. The stowable seat of claim 2 , further comprising a headrest coupled to an upper portion of the housing, wherein a bottom of the headrest is in contact with the web separator such that the shoulder harness webbing slides between the outer surface of the payout tube and the bottom of the headrest.

4. The stowable seat of claim 1 , wherein the third end of the payout tube is pivotally coupled to the first inner surface of the housing such that the payout tube pivots at the third end relative to the housing in response to the fourth end of the payout tube being decoupled from the second inner surface of the housing.

5. The stowable seat of claim 1 , wherein the fourth end of the payout tube is pivotally coupled to the second inner surface of the housing such that the payout tube pivots at the fourth end relative to the housing in response to the third end of the payout tube being decoupled from the first inner surface of the housing.

6. The stowable seat of claim 1 , wherein the payout tube comprises an extruded aluminum tubing.

7. The stowable seat of claim 1 , further comprising at least one of a first outer web separator or a second outer web separator coupled to an outer surface of the payout tube.

8. The stowable seat of claim 1 , wherein the payout tube comprises a cylindrical shape.

9. An inertia reel interface, comprising:
an inertia reel beam;
a payout tube; and
an inertia reel coupled to the inertia reel beam, wherein the inertia reel is configured to deploy a shoulder harness webbing over the payout tube, wherein a screw couples the inertia reel to the inertia reel beam through a shoulder bushing.

10. The inertia reel interface of claim 9 , further comprising a web separator coupled to an outer surface of the payout tube.

11. The inertia reel interface of claim 9 , wherein the payout tube comprises an extruded aluminum tubing.

12. The inertia reel interface of claim 9 , further comprising at least one of a first outer web separator or a second outer web separator coupled to an outer surface of the payout tube.

13. The inertia reel interface of claim 9 , wherein the payout tube is configured to pivot into at least one of a first access position or a second access position.

14. The inertia reel interface of claim 9 , wherein the payout tube comprises a cylindrical shape.
