The present disclosure relates generally to a quick engagement seat track fitting device, and method for the rapid attachment of a track mounted product of an aircraft or other vehicle.
Many track mounted products in aircrafts are mounted to seat tracks, which, in most cases, are universal and standard in the industry. Structural seat track fittings are required to mount and retain track mounted products to the airplane structure. Several types of seat track fittings are available and utilized today. These existing seat track fittings can be broken out into two main categories. The first category includes low cost systems that use multiple parts that are removably connected to one another. However, these seat track fittings are not installation friendly, requiring direct access to the seat track. Further, these components require hardware to assemble the multiple parts, resulting in increased installation and removal time as well as introducing ergonomic concerns due to the difficult installation. The second category of existing seat track fittings includes quick installation seat track fittings that are mostly utilized on high quantity items, such as seats themselves. Unfortunately, these quick installation features are accomplished through the utilization of relatively complex mechanisms, resulting in increased cost and certification effort.
As production rates and affordability of assembly become increasingly critical, the airline industry is in need of quick installation fittings that do not result in increased cost or compromise safety and ergonomics. Furthermore, airlines regularly re-configure interiors during an aircraft's lifecycle or have a need to remove track mounted products for other reasons, such as regular maintenance. Reduced track mounted product installation and removal time results in efficiencies for aircraft original equipment manufacturers (OEMs) as well as operators.
The present disclosure describes a seat track fitting design that simplifies the installation of seat track mounted track mounted products, without the utilization of complex mechanisms. The device described herein reduces the number of fasteners required for installation and enables placement of fastening hardware in convenient to access locations. The device utilizes simple machined parts without the need for moving components or internal mechanisms that drive complexity and cost. The seat track fitting design described herein employs a novel attachment method via a rotational motion (e.g., rotation along a longitudinal axis) about one row of an overhang portion of the seat track. This motion moves a flange of the device underneath the overhang portion of the seat track (capturing the overhang portion and locking the device to the track vertically in a Z-direction) and also drops shear bosses of the device into corresponding holes in the track (locking the device to the track horizontally in an X-Y direction). Then the track mounted product is installed via bayonet brackets that prevent the device from rotating out, while simultaneously fixing the track mounted product to the seat tracks.
In particular, in a first aspect, a device is described. The device includes an elongated member having a flange and a body. The elongated member includes a first end and a second end extending along a longitudinal axis of the elongated member. The flange includes a first side and a second side, the second side opposite the first side. The body is connected to and extends away from the second side of the flange. The body includes a first side, a second side, and a third side, wherein the first side of the body is opposite the second side of the body, and the third side of the body is opposite the first side of the flange. The first side of the body includes a protruding lip extending from at least a portion of the body between the first end and the second end of the elongated member. The device also includes a first alignment bore coupled to the first side of the flange between the first end and the second end of the elongated member. The device also includes a first boss extending from the second side of the body between the first end and the second end of the elongated member.
In a second aspect, a system is described. The system includes a first device comprising (i) a first elongated member having a first flange and a first body, wherein the first elongated member includes a first end and a second end extending along a longitudinal axis of the first elongated member, wherein the first flange includes a first side and a second side, the second side opposite the first side, wherein the first body is connected to and extends away from the second side of the first flange, wherein the first body includes a first side, a second side, and a third side, wherein the first side of the first body is opposite the second side of the first body, and the third side of the first body is opposite the first side of the first flange, and wherein the first side of the first body includes a first protruding lip extending from at least a portion of the first body between the first end and the second end of the first elongated member, (ii) a first alignment bore coupled to the first side of the first flange between the first end and the second end of the first elongated member, (iii) a second alignment bore coupled to the first side of the first flange between the first end and the second end of the first elongated member, (iv) a first boss extending from the second side of the first body between the first end and the second end of the first elongated member, and (v) a second boss extending from the second side of the first body between the first end and the second end of the first elongated member. The system also includes a second device comprising (i) a second elongated member having a second flange and a second body, wherein the second elongated member includes a first end and a second end extending along a longitudinal axis of the second elongated member, wherein the second flange includes a first side and a second side, the second side opposite the first side, wherein the second body is connected to and extends away from the second side of the second flange, wherein the second body includes a first side, a second side, and a third side, wherein the first side of the second body is opposite the second side of the second body, and the third side of the second body is opposite the first side of the second flange, and wherein the first side of the second body includes a second protruding lip extending from at least a portion of the second body between the first end and the second end of the second elongated member, (ii) a third alignment bore coupled to the first side of the second flange between the first end and the second end of the second elongated member, (iii) a fourth alignment bore coupled to the first side of the second flange between the first end and the second end of the second elongated member, (iv) a third boss extending from the second side of the second body between the first end and the second end of the second elongated member, and (v) a fourth boss extending from the second side of the second body between the first end and the second end of the second elongated member.
In a third aspect, a method is described. The method includes positioning a first device into an opening in a first track, wherein the first track includes an overhang portion to receive a protruding lip of a body of an elongated member of the first device to thereby prevent vertical movement of the first device with respect to the first track. The method also includes rotating the first device with respect to the first track until a first boss and a second boss of the first device are positioned in corresponding cutouts in the first track to thereby prevent horizontal movement of the first device with respect to the first track.
