Assemblies and methods for securing an element to an aircraft seat track break
View Patent ↗Adapter devices are provided that, when installed on an aircraft seat track break area, allow for the installation and/or positioning of passenger seats thereat. The devices include a main body having two portions. One end of the portion is integrated to a fork-shaped part 2 which defines a half-opening 3. Close to the end of the other portion there is provided a pair of half-tabs which are symmetrically disposed in relation to one another on each side of the body. Pairs of symmetrically disposed semi-circular tabs are provided on the main body. Threaded pass-through holes are located one of the body portions so as to threadably accommodate retaining discs in the form of screw screws heads provided with screws which are installed in the threaded holes.
1. An assembly which comprises a pair of adapter devices for securing an aircraft passenger seat onto a seat track break between two seat track segments in an aircraft fuselage, wherein each of the adapter devices comprises:
a main body adapted for operative engagement with a channel of the seat track so as to be positioned at the seat track break, the main body having opposed front and rear end portions joined to each other, and wherein the main body includes at least one spaced-apart pair of engagement tabs between the front and rear end portions thereof, and wherein the front end portion includes a fork-shaped part which defines a half-opening for receiving a connection pin associated with a foot of an aircraft passenger seat, and wherein
the adapter devices are symmetrically disposed in relation to one another such that the fork-shaped part of one adapter device is engaged with the forked-shaped part of another adapter device so that both half-openings thereof are joined to form a circular opening surrounding the connection pin of the foot of the aircraft passenger seat.
2. The assembly of claim 1 , wherein the main body of at least one of the adapter devices includes at least one threaded pass-through hole, and wherein the at least one adapter device further comprises at least one retaining disc having a screw portion which is installed in the pass-through hole on the main body to positionally retain the adapter device on the seat track.
3. The assembly of claim 1 or 2 , wherein the half-opening defined by the fork shaped part of each of the adapter devices has a semi-circular or rounded-rectangular shape.
4. The assembly of claim 1 , wherein the rear end portion of the main body of at least one of the adapter devices includes a pair of half-tabs.
5. A method of assembling an aircraft passenger seat to a seat track comprising the steps of:
(a) providing an assembly according to claim 1 ;
(b) positioning and fastening a rear one of the adapter devices onto the seat track;
(c) installing and positioning the aircraft passenger seat in the seat track in operative relationship to the rear one of the adapter devices; and
(d) positioning and fastening a front one of the adapter devices onto the seat track so as to engage a pin associated with a foot of the passenger seat and positionally fix the passenger seat to the seat track.
6. An assembly for securing an element to an aircraft seat track of the type having a channel, a plurality of spaced access regions and a plurality of retaining regions located between adjacent access regions, the assembly comprising:
forward and rearward adapter devices for securing the aircraft passenger seat to the seat track, wherein
each of the forward and rearward adapter devices includes an elongate body portion configured to be received within the channel of the seat track, the body portion having an arcuate engagement region at one end thereof, and at least one opposed pair of tabs protruding outwardly from the body portion, the tabs being configured to be received by a selected one of the access regions to allow for movement of the elongate body portion within the channel so that the tabs may be positioned in retaining engagement with a selected one of the retaining regions, and wherein
the forward and rearward adapter devices are positionable within the channel of the seat track such that the arcuate engagement regions thereof are in opposition to one another and in engagement with the element to be secured to the seat track.
7. The assembly as in claim 6 , wherein the element is a pin associated with a foot of an aircraft passenger seat.
8. The assembly as in claim 6 , wherein the main body includes a pair of half-tabs at a rear end portion thereof.
9. An adapter device as in claim 6 , wherein the main body includes at least one threaded hole, and wherein the adapter device further comprises a threaded screw adapted for threaded engagement with the hole.
10. An adapter device as in claim 9 , wherein the threaded screw includes a retaining disc.
