Abstract

A system and method for restraining movement using a first adapter and a second adapter. The first adapter includes a first body, a first engagement component connected to the first body, and a first fastening component configured to fasten to a first attachment point of an aircraft. The second adapter includes a second body, a second engagement component connected to the second body, and a second fastening component configured to fasten to a second attachment point of the aircraft. The second attachment point is different from the first attachment point. The first and second engagement components are each configured to connect with a harness, and the first fastening component has a physical structure different from a physical structure of the second fastening component.

First claim

What is claimed is:

1. A restraint system comprising:
a first adapter comprising:
a first body having a height defined by a distance from a first surface to a second surface opposite the first surface, the first body including a plurality of parallel cylindrical bores extending therethrough from the first surface to the second surface, wherein a cylindrical counterbore is defined in the second surface around each of the plurality of parallel cylindrical bores, the first surface defining a first plane, the second surface defining a second plane substantially parallel with the first plane;
a first engagement component rotatably connected to the first body via the second surface, wherein the first engagement component is configured to rotate about a first axis that is substantially orthogonal to the second plane; and
a first fastening component configured to fasten to a first attachment point of an aircraft via a threaded connection, wherein the first surface is configured to lie flush against the first attachment point while the first fastening component is fastened to the first attachment point; and

a second adapter comprising:
a second body comprising a first mounting plate and a second mounting plate coupled to the first mounting plate, wherein the first mounting plate comprises a first plurality of legs, wherein the second mounting plate comprises a second plurality of legs, and wherein the first mounting plate and the second mounting plate are coupled together via a first fastener extending through a first leg of the first plurality of legs and a second leg of the second plurality of legs;
a second engagement component rotatably connected to the second body; and
a second fastening component configured to mechanically fasten to a second attachment point of the aircraft, the second attachment point different from the first attachment point, wherein the first engagement component and the second engagement component are each configured to connect with a safety harness, via a respective lanyard.

2. The restraint system according to claim 1 , wherein the second engagement component is rotatably coupled to the first mounting plate via a third surface, wherein the second mounting plate defines a fourth surface, the fourth surface having a first edge and a second edge, wherein the second fastening component is coupled to the second mounting plate proximate to the first edge, wherein the first mounting plate is coupled to the second mounting plate proximate to the second edge, and wherein the third surface and the fourth surface are substantially perpendicular.

3. The restraint system according to claim 2 , wherein the third surface defines a third plane, wherein the second engagement component is configured to rotate about a second axis that is substantially orthogonal to the third plane.

4. The restraint system according to claim 2 , wherein the third surface defines a first major plane of the first mounting plate, and wherein the fourth surface defines a second major plane of the second mounting plate.

5. The restraint system according to claim 1 , wherein the first fastener includes a first bolt, and wherein the first mounting plate and the second mounting plate are further coupled together via a second bolt extending through a third leg of the first plurality of legs and a fourth leg of the second plurality of legs.

6. The restraint system according to claim 1 , wherein the plurality of parallel cylindrical bores are configured to correspond to cylindrical bores in the first attachment point to allow for fastening the first adapter to the first attachment point.

7. The restraint system according to claim 6 , wherein the first body includes a central cylindrical bore extending from the second surface through a portion of the height of the first body, wherein at least a portion of the first engagement component is disposed in the central cylindrical bore.

8. The restraint system according to claim 1 , wherein the second fastening component includes a third plurality of legs defining a slot between the third plurality of legs, each leg of the third plurality of legs having a hole for receiving a fastener therethrough.

9. The restraint system according to claim 8 , wherein the fastener is a pin, the pin arranged to extend through the third plurality of legs and through the second attachment point.

10. The restraint system according to claim 9 , wherein the second attachment point is a lug disposed on an aft section of an aircraft wing.

11. The restraint system according to claim 10 , wherein the second adapter is configured to cover a portion of the aft section of the aircraft wing, wherein a surface of the second adapter is configured to prevent alteration of a surface of the aircraft wing.

12. The restraint system according to claim 1 , wherein the first body includes a surface and a recess defined in the surface, and the first engagement component is connected to the first body by a nut inserted into the recess in the surface of the first body.

13. The restraint system according to claim 1 , wherein the first and second engagement components are first and second rings each having a stem, and the first and second adapters each include a bushing configured to receive therein the stem of the respective ring.

14. The restraint system according to claim 1 , wherein the respective lanyards are configured to connect to the safety harness.

15. The restraint system according to claim 14 , wherein the respective lanyards are sized to define a maximum movement direction along a wing of the aircraft.

16. A method for securing an operator to a component of an aircraft, the component including a forward attachment point, and an aft attachment point, the method comprising:
connecting a forward adapter to the forward attachment point, the forward adapter comprising:
a first body having a height defined by a distance from a first surface to a second surface opposite the first surface, the first body including a plurality of parallel cylindrical bores extending therethrough from the first surface to the second surface, wherein a cylindrical counterbore is defined in the second surface around each of the plurality of parallel cylindrical bores, the first surface defining a first plane, the second surface defining a second plane substantially parallel with the first plane;
a first engagement component rotatably connected to the first body via the second surface, wherein the first engagement component is configured to rotate about a first axis that is substantially orthogonal to the second plane; and
a first fastening component configured to connect the first body of the forward adapter to the forward attachment point via a threaded connection, wherein the first surface is configured to lie flush against the forward attachment point while the first fastening component is fastened to the forward attachment point;

connecting an aft adapter to the aft attachment point, the aft adapter comprising:
a second body comprising a first mounting plate and a second mounting plate coupled to the first mounting plate, wherein the first mounting plate comprises a first plurality of legs, wherein the second mounting plate comprises a second plurality of legs, and wherein the first mounting plate and the second mounting plate are coupled together via a first fastener extending through a first leg of the first plurality of legs and a second leg of the second plurality of legs;
