Abstract
Description
- The present disclosure relates generally to convenience and/or emergency lighting for a passenger vehicle, such as an aircraft, and to related armrest assemblies, seat assemblies, and methods of manufacturing and/or servicing.
- When passengers are seated in a seat of a passenger vehicle, such as an aircraft, a watercraft, and/or a land vehicle, the passengers frequently desire to have additional lighting to facilitate reading and the like. For example, commercial aircraft are typically equipped with a plurality of overhead lighting units, with each lighting unit positioned to provide light to a corresponding individual seat position. However, use of such lights may be undesirable for a variety of reasons, including difficulty in properly positioning the light, undesirable light being cast on/near adjacent seat positions, difficulty in reaching the corresponding light switch, and the like.
- Accordingly, there is a need for alternative approaches to providing convenience and/or emergency light to passengers in a passenger vehicle. Such approaches should advantageously be adjustable by the passenger, and be space efficient.
- Aspects of the present disclosure are generally directed to an armrest assembly that includes a light source, a seat assembly that includes the armrest assembly, and related method(s) of manufacturing or servicing. In general, the armrest assembly includes a light assembly and an armrest. The light assembly includes a light source that is supported by an articulating support such that it can be positioned in a variety of locations. The articulating support is pivotally mounted to the armrest in a forward portion of a side notch of the armrest that extends along the lateral edge of the armrest. The armrest assembly is configured such that the light source is disposed in the side notch and oriented to direct light from the side notch away from the armrest when the light assembly is in a stowed configuration. The articulating support may be moved so that the light source is disposed out of the side notch, so as to provide a reading light.
- In one or more aspects, the present disclosure is directed to an armrest assembly for a passenger vehicle. The armrest assembly includes an armrest and a light assembly. The armrest has an upper surface extending along a first longitudinal axis. The armrest has a side notch defined therein, with the side notch extending parallel to the first longitudinal axis and disposed at a lateral edge of the upper surface such that the side notch defines a lateral boundary of the upper surface. The side notch has a forward portion and a rearward portion. The light assembly is moveably mounted to the armrest and has an articulating support and a light source. The articulating support has a base section pivotally mounted to the armrest in the forward portion of the side notch and an opposing free end. The light source is mounted to the articulating support so as to be closer to the free end than the base section. The light assembly is movable between a stowed configuration and at least one deployed configuration. When the light assembly is in the stowed configuration: 1) both the articulating support and the light source of the light assembly are disposed in the side notch; 2) the articulating support is disposed parallel to the first longitudinal axis; and 3) the light source is oriented to direct light from the side notch away from the armrest. When the light assembly is in the deployed configuration: 1) the free end of the articulating support is disposed outside the side notch; and 2) the light source is disposed outside the side notch.
- In one or more other aspects, the present disclosure is directed to a seat assembly for a passenger vehicle. The seat assembly includes a passenger seat and an armrest assembly disposed adjacent the passenger seat. The armrest assembly includes an armrest and a light assembly. The armrest has an upper surface extending along a first longitudinal axis. The armrest has a side notch defined therein, with the side notch extending parallel to the first longitudinal axis and disposed at a lateral edge of the upper surface such that the side notch defines a lateral boundary of the upper surface. The side notch has a forward portion and a rearward portion. The light assembly is moveably mounted to the armrest and has an articulating support and a light source. The articulating support has a base section pivotally mounted to the armrest in the forward portion of the side notch and an opposing free end. The light source is mounted to the articulating support so as to be closer to the free end than the base section. The light assembly is movable between a stowed configuration and at least one deployed configuration. When the light assembly is in the stowed configuration: 1) both the articulating support and the light source of the light assembly are disposed in the side notch; 2) the articulating support is disposed parallel to the first longitudinal axis; and 3) the light source is oriented to direct light from the side notch away from the armrest. When the light assembly is in the deployed configuration: 1) the free end of the articulating support is disposed outside the side notch; and 2) the light source is disposed outside the side notch.
- In one or more other aspects, the present disclosure is directed to a method of manufacturing or servicing an aircraft having a passenger cabin. The method includes installing an armrest assembly in the passenger cabin adjacent a passenger seat. The armrest assembly includes an armrest and a light assembly. The armrest has an upper surface extending along a first longitudinal axis. The armrest has a side notch defined therein, with the side notch extending parallel to the first longitudinal axis and disposed at a lateral edge of the upper surface such that the side notch defines a lateral boundary of the upper surface. The side notch has a forward portion and a rearward portion. The light assembly is moveably mounted to the armrest and has an articulating support and a light source. The articulating support has a base section pivotally mounted to the armrest in the forward portion of the side notch and an opposing free end. The light source is mounted to the articulating support so as to be closer to the free end than the base section. The light assembly is movable between a stowed configuration and at least one deployed configuration. When the light assembly is in the stowed configuration: 1) both the articulating support and the light source of the light assembly are disposed in the side notch; 2) the articulating support is disposed parallel to the first longitudinal axis; and 3) the light source is oriented to direct light from the side notch away from the armrest. When the light assembly is in the deployed configuration: 1) the free end of the articulating support is disposed outside the side notch; and 2) the light source is disposed outside the side notch. In some aspects, the method optionally further includes: 1) moving the light assembly from the stowed configuration to the deployed configuration; and 2) shining light from the light source toward the passenger seat while the light assembly is in the deployed configuration.
- In some aspects of the armrest assembly itself and/or the armrest assembly as part of the seat assembly, and/or the related methods, the articulating support comprises a first segment, a second segment, and a third segment, arranged in series. The first segment is moveably mounted to the armrest in the forward portion of the side notch for rotation about a first pivot axis. The first segment has a proximal portion through which the first pivot axis extends, and a distal portion. The second segment is moveably mounted to the distal portion of the first segment for rotation relative to the first segment. The third segment is moveably mounted to the second segment opposite the first segment. The light source is disposed in the third segment. In some aspects, the third segment is constrained to remain disposed parallel to the second segment and constrained to a single degree of freedom relative to the second segment. For example, the third segment is rotatable relative to the second segment about a second longitudinal axis of the second segment.
- The features, functions, and advantages that have been discussed can be achieved independently in various aspects or may be combined in yet other aspects further details of which can be seen with reference to the following description and the drawings.
- Having thus described the disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale.

FIG. 11 shows a flowchart pertaining to aspects of the present disclosure. - Aspects of the present disclosure are directed to an
armrest assembly 30 that includes alight source 80, aseat assembly 20 that includes thearmrest assembly 30, and related method(s) of manufacturing or servicing. In general, thearmrest assembly 30 includes alight assembly 31 and anarmrest 32. Thelight assembly 31 includeslight source 80 that is supported by an articulatingsupport 50 such that it can be positioned in a variety of locations. The articulatingsupport 50 is pivotally mounted to an armrest 32 in aforward portion 42 of aside notch 40 that extends along thelateral edge 36 of thearmrest 32. Thearmrest assembly 30 is configured such that thelight source 80 is disposed in theside notch 40 and oriented to direct light 84 from theside notch 40 away from the armrest 32 when thelight assembly 31 is in a stowed configuration. The articulatingsupport 50 may be moved so that thelight source 80 is disposed out of theside notch 40, so as to provide a reading light. - Referring to
FIGS. 1-2 , anexemplary aircraft 10 is shown. Theaircraft 10 has apassenger cabin 12. Typically, a plurality ofseats 22 are positioned in thepassenger cabin 12 for supporting passengers during transit. In some aspects, theseats 22 are arranged in rows, and someadjacent seats 22 are affixed in groups, such as in three-seat arrangements. A seat back 24 is associated with eachpassenger seat 22. Eachpassenger seat 22 has one or more armrests 32. One or more of thearmrests 32 are provided by anarmrest assembly 30. SeeFIGS. 3-10 . Note that, for simplicity, anaircraft 10 is used as an illustrative example of a passenger vehicle; but the passenger vehicle is, in various aspects, any of anaircraft 10, a watercraft, and/or a land vehicle. Thus, in some aspects, thearmrest assembly 30 described herein is disposed in apassenger cabin 12 of anaircraft 10. - The
armrest assembly 30 includes anarmrest 32 and alight assembly 31. Thearmrest 32 has anupper surface 34 extending along a firstlongitudinal axis 39. Theupper surface 34 is configured to support a passenger's arm during transit in theaircraft 10. Thearmrest 32 has aside notch 40 defined therein. Theside notch 40 is disposed at alateral edge 36 of theupper surface 34 such that theside notch 40 defines a lateral boundary of theupper surface 34. Being disposed at thelateral edge 36 of theupper surface 34, theside notch 40 is disposed at the conceptual corner between theupper surface 34 of thearmrest 32 and aside surface 38 of the armrest 32 (e.g., the side oriented toward the passenger seat 22); seeFIG. 8 . Thus, there is a vertical offset D between the upward facingupper surface 34 of the armrest 32, and the upward facingupper surface 46 of theside notch 40. Theside notch 40 extends parallel to the firstlongitudinal axis 39. Theside notch 40 has aforward portion 42 and arearward portion 44, with therearward portion 44 disposed nearer the rear of the passenger seat 22 (toward the seat back 24), and theforward portion 42 disposed nearer the front of thepassenger seat 22. In some aspects, theside notch 40 has a lateral width W2 that is not more than 20% of a lateral width W1 of theupper surface 34 of thearmrest 32. - The
light assembly 31 is moveably mounted to thearmrest 32 and includes an articulatingsupport 50 and alight source 80. The articulatingsupport 50 has abase section 51 pivotally mounted to the armrest 32 in theforward portion 42 of theside notch 40 and an opposingfree end 71. Thelight source 80 is mounted to the articulatingsupport 50 so as to be closer to thefree end 71 than thebase section 51. Referring toFIGS. 7-8 , in some aspects, the articulatingsupport 50 includes afirst segment 52, asecond segment 60, and athird segment 70, arranged in series. Thefirst segment 52 is moveably mounted to the armrest 32 in theforward portion 42 of theside notch 40 for rotation about afirst pivot axis 53. Thefirst pivot axis 53 advantageously coincides with a shaft of the armrest 32 that extends laterally into theside notch 40. Thefirst segment 52 has aproximal portion 54 through which thefirst pivot axis 53 extends, and adistal portion 55. In some aspects, thefirst segment 52 is moveably mounted to the armrest 32 so as to be constrained to a single degree of freedom relative to the armrest 32 (i.e., rotation about the first pivot axis 53). Thefirst segment 52 acts as thebase section 51. Thefirst segment 52 is advantageously longitudinally rigid and straight. - The
second segment 60 is moveably mounted to thedistal portion 55 of thefirst segment 52 for rotation relative to thefirst segment 52. In some aspects, thesecond segment 60 is moveably mounted to thedistal portion 55 of thefirst segment 52 for rotation about asecond pivot axis 63 that extends through thedistal portion 55 of thefirst segment 52 and aproximal portion 64 of thesecond segment 60. In some aspects, thesecond pivot axis 63 is orthogonal to thefirst pivot axis 53. In some aspects, thesecond segment 60 is constrained to a single degree of freedom relative to the first segment 52 (i.e., rotation about the second pivot axis 63). Thesecond segment 60 extends along a secondlongitudinal axis 66. Thesecond segment 60 is advantageously longitudinally rigid and straight. - The
third segment 70 is moveably mounted to thesecond segment 60 opposite thefirst segment 52. In some aspects, thethird segment 70 is constrained to remain disposed parallel to thesecond segment 60 and constrained to a single degree of freedom relative to thesecond segment 60. For example, thethird segment 70 may include apost 72 that extends into a correspondinghole 62 in thesecond segment 60, with thehole 62 aligned with the secondlongitudinal axis 66 of thesecond segment 60. Thus, thethird segment 70 is rotatable relative to thesecond segment 60 about the secondlongitudinal axis 66 of thesecond segment 60. In some aspects, thethird segment 70 is rotatable 360° relative to thesecond segment 60 about the secondlongitudinal axis 66 of thesecond segment 60. In other aspects, the rotation of thethird segment 70 is limited to less than 360°, such as 330°, 270°, 180°, 120°, or 90°. Thethird segment 70 acts as thefree end 71. Thethird segment 70 is advantageously longitudinally rigid and straight. - The
light source 80 is advantageously disposed in thethird segment 70. Thelight source 80 is of any suitable type, such as one or more LEDs, a light bulb, an emitting end of an optical fiber, or the like. Thelight source 80 is optionally covered by a suitable lens or protective cover (not shown), which is optionally colored/tinted. Power/light is supplied to thelight source 80 in any suitable manner, such as post and ring electrical connections, wires, flexible circuit traces, etc. - The
light assembly 31 is movable between a stowed configuration and at least one deployed configuration. When thelight assembly 31 is in the stowed configuration: 1) both the articulatingsupport 50 and thelight source 80 of thelight assembly 31 are disposed in theside notch 40; 2) the articulating support 50 (includingbase section 51 and free end 71) is disposed parallel to the firstlongitudinal axis 39; and 3) thelight source 80 is oriented to direct light 84 from theside notch 40 away from thearmrest 32. SeeFIG. 4 . When thelight assembly 31 is in the deployed configuration: 1) thefree end 71 of the articulatingsupport 50 is disposed outside theside notch 40; and 2) thelight source 80 is disposed outside theside notch 40. SeeFIG. 5 andFIG. 6 . Note that at least a portion of thebase section 51 remains disposed in theside notch 40 in the deployed configuration.FIG. 5 illustrates a first deployed configuration, where thefirst segment 52,second segment 60, andthird segment 70 of the articulatingsupport 50 are arranged linearly, but oriented transverse to the firstlongitudinal axis 39 of thearmrest 32.FIG. 6 illustrates a second deployed configuration, where thesecond segment 60 andthird segment 70 are linearly arranged relative to each other, but disposed transverse to thefirst segment 52, and thefirst segment 52 is oriented transverse to the firstlongitudinal axis 39 of thearmrest 32. The second deployed configuration may be referred to as the “fully deployed” configuration. In the second deployed configuration, thesecond segment 60 is advantageously perpendicular to thefirst segment 52, although other relative angular positions are also contemplated. - In some aspects, when the
light assembly 31 is in the stowed configuration, thelight source 80 is oriented to direct light 84 from theside notch 40 laterally away from thearmrest 32. In other aspects, when thelight assembly 31 is in the stowed configuration, thelight source 80 is oriented to direct light 84 from theside notch 40 vertically away from thearmrest 32. In some aspects, the cross-sectional height of the articulatingsupport 50 is advantageously equal to the vertical offset D, so that, in the stowed configuration, thelight assembly 31 forms a continuation ofupper surface 34 ofarmrest 32, and/or the cross-sectional width of the articulatingsupport 50 is advantageously equal to the lateral width of theside notch 40, so that, in the stowed configuration, thelight assembly 31 forms a continuation of side surface ofarmrest 32. SeeFIG. 10 . - In some aspects, the pivoting connections between the
first segment 52 and thearmrest 32, and/or between thefirst segment 52 andsecond segment 60, and/or between thesecond segment 60 and thethird segment 70, are provided with suitable detents, friction connections, or the like to all the corresponding connections to be selectively/releasably held in at a desired relative angular position. - In some aspects, a
switch 90 is disposed on theupper surface 34 of the armrest 32, with theswitch 90 operatively connected to thelight source 80 and operative to control an on/off state of thelight source 80. In some aspects,light source 80 automatically turns on when thelight assembly 31 is moved to the deployed configuration, and shuts off when thelight assembly 31 is moved to the stowed configuration, with theswitch 90 optionally providing an override function to allow thelight source 80 to be turned on by the passenger when thelight assembly 31 is in the stowed configuration. Theswitch 90 optionally provides brightness control for thelight source 80. - In some aspects, the
light source 80 may be operatively connected to the emergency lighting systems of the passenger vehicle (e.g., aircraft 10), if present, so that thelight source 80 may be automatically turned on in emergency situations. - In some aspects, a
seat assembly 20 is provided. Theseat assembly 20 includes apassenger seat 22 and thearmrest assembly 30 described above. Thus, theseat assembly 20 includesarmrest assembly 30 disposed adjacent to thepassenger seat 22, with thearmrest assembly 30 including anarmrest 32 and alight assembly 31. Thearmrest 32 has theupper surface 34 extending along a firstlongitudinal axis 39. Thearmrest 32 has theside notch 40 defined therein, with theside notch 40 extending parallel to the firstlongitudinal axis 39 and disposed at alateral edge 36 of theupper surface 34 such that theside notch 40 defines a lateral boundary of theupper surface 34. Theside notch 40 has aforward portion 42 and arearward portion 44. Thelight assembly 31 is moveably mounted to thearmrest 32 and has an articulatingsupport 50 and alight source 80. The articulatingsupport 50 has abase section 51 pivotally mounted to the armrest 32 in theforward portion 42 of theside notch 40 and an opposingfree end 71. Thelight source 80 is mounted to the articulatingsupport 50 so as to be closer to thefree end 71 than thebase section 51. Thelight assembly 31 is movable between a stowed configuration and at least one deployed configuration. When thelight assembly 31 is in the stowed configuration: 1) both the articulatingsupport 50 and thelight source 80 of thelight assembly 31 are disposed in theside notch 40; 2) the articulating support 50 (includingbase section 51 and free end 71) is disposed parallel to the firstlongitudinal axis 39; and 3) thelight source 80 is oriented to direct light 84 from theside notch 40 away from thearmrest 32. When thelight assembly 31 is in the deployed configuration: 1) thefree end 71 of the articulatingsupport 50 is disposed outside theside notch 40; and 2) thelight source 80 is disposed outside theside notch 40. In some aspects, when thelight assembly 31 is in the stowed configuration, thelight source 80 is oriented to direct light 84 from theside notch 40 laterally away from the armrest 32 toward thepassenger seat 22. Such lateral directing of the light provides a passenger with side lighting, which may help in locating dropped items and/or otherwise illuminating items in/near the passenger's lap when appropriate. - In other aspects, the
armrest assembly 30 described herein may be used in a method of manufacturing or servicing anaircraft 10 having apassenger cabin 12. The method (100) includes installing (110) thearmrest assembly 30 in thepassenger cabin 12 adjacent apassenger seat 22. Thearmrest assembly 30 includes anarmrest 32 and alight assembly 31. Thearmrest 32 has anupper surface 34 extending along a firstlongitudinal axis 39. Thearmrest 32 has aside notch 40 defined therein, with theside notch 40 extending parallel to the firstlongitudinal axis 39 and disposed at alateral edge 36 of theupper surface 34 such that theside notch 40 defines a lateral boundary of theupper surface 34. Theside notch 40 has aforward portion 42 and arearward portion 44. Thelight assembly 31 is moveably mounted to thearmrest 32 and has an articulatingsupport 50 and alight source 80. The articulatingsupport 50 has abase section 51 pivotally mounted to the armrest 32 in theforward portion 42 of theside notch 40 and an opposingfree end 71. Thelight source 80 is mounted to the articulatingsupport 50 so as to be closer to thefree end 71 than thebase section 51. Thelight assembly 31 is movable between a stowed configuration and at least one deployed configuration. When thelight assembly 31 is in the stowed configuration: 1) both the articulating support 50 (includingbase section 51 and free end 71) and thelight source 80 of thelight assembly 31 are disposed in theside notch 40; 2) the articulatingsupport 50 is disposed parallel to the firstlongitudinal axis 39; and 3) the light is oriented to direct light 84 from theside notch 40 away from thearmrest 32. When thelight assembly 31 is in the deployed configuration: 1) the free end of the articulatingsupport 50 is disposed outside theside notch 40; and 2) the light is disposed outside theside notch 40. In some aspects, the method further includes 1) moving (120) thelight assembly 31 from the stowed configuration to the deployed configuration; and 2) shining (130) light from thelight source 80 toward thepassenger seat 22 while thelight assembly 31 is in the deployed configuration. - The various portions of the
light assembly 31,armrest assembly 30, and/orseat assembly 20 are made from any suitable materials, such as aluminum, steel, plastic (with or without reinforcement), foam, etc. The materials chosen should be strong enough to support the passenger with suitable safety margin. And, in some aspects, the articulatingsupport 50 of thelight assembly 31 optionally includes cushioning on the perimeter surfaces thereof that face upward and/or laterally toward theseat 22 in the stowed configuration, to increase passenger comfort when the passenger rests their arm on the articulatingsupport 50 in the stowed configuration.
