    description
    TECHNICAL FIELD The technical field relates generally to aircraft and seat labyrinth assemblies for aircraft, and more particularly relates to aircraft and seat labyrinth assemblies that define a portion of a free plane of motion into which the seat cannot move.
    BACKGROUND A conventional passenger aircraft has a fuselage, a cabin interior within the fuselage, and a floor that defines a bottom of the cabin interior and that is supported by the fuselage. A seat base is typically attached to the floor and a seat frame is selectively attached to the seat base. When released from engagement with the seat base, the seat frame can move freely within a portion of a plane of movement in which the seat base is within the seat frame. However, such free movement may be undesirable if free movement of the seat frame results in a seat occupant's hand being pinched between the seat and another object, such as a sidebar or a table within the aircraft interior.
    It is therefore desirable to provide an improved aircraft and systems for limiting portions of the free range of motion of the seat. In addition, other desirable features and characteristics will become apparent from the following summary and detailed description, and the appended claims, taken in conjunction with the accompanying drawings and this background.
    SUMMARY OF EMBODIMENTS Various non-limiting embodiments of aircraft, seat assemblies, and aircraft interiors are disclosed herein.
    [0005] In a first non-limiting embodiment, a seat assembly has a seat base, a seat frame, and a seat labyrinth. The seat base is designed so that it can be attached to a floor. The seat frame is selectively attached to the seat base and has a frame rail that circumscribes the seat base to define a boundary area in which the seat base can translate relative to the seat frame. The seat labyrinth is configured to extend a perimeter of the seat base to define a space area and to guide the movement of the seat frame around the space area.
    In a second non-limiting embodiment, an aircraft interior, but not limited to, has a floor, a seat base attached to the floor, a seat frame, a seat body, an obstacle, and a seat labyrinth. The seat frame is selectively attached to the seat base and has a frame rail that circumscribes the seat base to define a boundary area in which the seat base can translate relative to the seat frame. The seat body is attached to the seat frame and has an arm section. The obstacle is located near the arm portion of the seat body. The seat labyrinth is designed such that it guides the seat frame around a space area within the delimitation area in order to maintain a predetermined space between the arm section and the obstacle.

    DETAILED DESCRIPTION The following detailed description is intended to be exemplary only and is not intended to limit the invention or the application and uses of the invention. Furthermore, it is not aimed at by any theory
    CH 713 987 A2, which is represented in the preceding background or the following detailed description.
    Various non-limiting embodiments of aircraft seat assemblies and aircraft interiors are disclosed herein. The embodiments include various configurations of a seat tracking labyrinth that limits movement of a seat frame in a portion of a free range of motion to maintain a gap between the seat and an obstacle near the seat. A better understanding of the seat assemblies and aircraft interiors can be obtained by viewing the figures that accompany this application, along with consideration of the following detailed description.
    1A-C an aircraft interior 100 is shown in supervision according to the teachings of the present disclosure. The aircraft interior 100 has a floor 110, an obstacle 112, and a seat assembly 114. In the present example, the aircraft interior 100 is a cabin of a jet aircraft. Aircraft interior components 100 may be arranged in any other type of vehicle, machine, or seating, including, but not limited to, helicopters, propellers, submarines, cinemas, airships, lounges, and other locations, without departing from the scope of the present disclosure departing.
    [0011] The floor 110 supports the support assembly 114. In the present example, floor 110 is mounted within the fuselage of the aircraft and has floor rails (not shown) for mounting seat assembly 114, as is known to those skilled in the art.
    In the present example, the obstacle 112 is a sidebar of an aircraft cabin. It is noted that the obstacle 112 may be any physical object in a substantially fixed location near the seat assembly without departing from the scope of the present disclosure. For example, obstacle 112 may be a table, another seat, a partition, and other physical objects. The obstacle 112 has a flat ledge section 120 and a deep ledge section 122. The flat ledge section 120 is arranged on the side of the seat assembly 114, and the deep ledge section 122 is at least partially arranged directly in front of the seat assembly 114. Since conventional seat assemblies do not limit translational movement of the seat in the forward direction towards the deep bar section 122, it can happen with such conventional seat assemblies that the armrest collides with the side bar obstacle 112.
    2-3, further referring to FIGS. 1A-B, additional components of the seat assembly 114 are shown. The seat assembly 114 has a seat base 130, a seat frame 132, a seat body 134, and a seat labyrinth assembly 136.
    [0014] The seat base 130 has a component 140 attached to the floor and a swivel box 142. The bottom mounted component 140 is attached to the bottom 110 so that the bottom mounted component remains stationary with respect to the bottom 110. For example, the bottom mounted component 140 may be attached to C-channel guides (not shown) in the bottom 110 to secure the bottom mounted component to the bottom 110, as is known by those skilled in the art.
    The seat base 130 selectively attaches the seat frame 132 to the floor 110 using a conventional user-operated locking mechanism (not shown). When the seat frame 132 is attached to the floor 110, the locking mechanism limits movement of the seat frame 132 relative to the seat base 130. Therefore, the seat frame 132 is immovably attached to the floor 110 when the locking mechanism is engaged. When the seat frame 132 is not attached to the seat base 130, the seat frame 132 is free to translate and pivot about the seat base 130 within the limits set by the seat frame 132 and the seat labyrinth assembly 136. as explained below.
    In the present example, the seat base 130 employs a scepter mechanism to facilitate rotation of the pivot box 142 about the component 140 attached to the floor. Tracking tubes facilitate translational movement of the seat frame 132 relative to the seat base 130, as is known to those skilled in the art. Numerous variations of movement and locking mechanisms are known to those skilled in the art and no further complicated details are described in this regard.
    The seat frame 132 is selectively attached to the seat base 130 and has a frame rail 150. The term "selectively attached" as used herein refers to the ability of the seat frame 132 to be locked in place with respect to the seat base 130 or to be detached from the seat base 130 by using the locking mechanism.
    The seat frame 132 is a structural assembly that supports the seat body 134 and a person sitting in the seat body 134. The frame rail 150 runs essentially parallel to the floor 110 and has a rail flange 151 parallel to the floor 110 and opposite it. The frame rail 150 circumscribes the seat base 130 to define a boundary area 152 in which the seat base 130 can translate with respect to the seat frame. The term "rewrite" as used here means that a line is drawn around or a surrounding border is drawn, in accordance with common usage. Since the seat base 130 is attached to the floor 110, the seat frame 132 can be viewed to move with respect to the seat base 130 insofar as the seat frame 132 is not caused to move beyond a distance at which the seat base 130 comes into contact with the frame rail 150 at an edge of the delimitation area 152.
    CH 713 987 A2
    For example, a seat occupant may release the locking mechanism and apply translational force to the seat body 134 in the forward direction, in the backward direction, in the left direction, in the right direction, or in a combination of directions. The translational force causes the seat body 134 to move, which in turn causes the seat frame 132 to move.
    In the present example, the seat frame 132 performs a translational movement on a plane that is substantially parallel to the floor 110. The seat frame 132 is free to translate along the longitudinal and transverse directions of the aircraft while the seat frame 132 is positioned so that the seat base 130 is not in contact with the frame rail 150 and while the seat labyrinth assembly 136 does not restrict movement , When the frame rail 150 comes into contact with the seat base 130, the seat base 130 transmits the translational force to the floor 110, and further movement of the seat frame 132 is limited by the interaction of the seat base 130 and the frame rail 150.
    The seat body 134 is attached to the seat frame 132, and provides surfaces that support a seated occupant of the seat assembly 114. The seat body 134 has a seat section 160, a backrest section 162, and an armrest section 164. The seat occupant sits on the seat section 130 with a viewing direction away from the backrest section 162.
    The seat labyrinth assembly 136 is configured to extend a perimeter of the seat base 130 to prevent movement of the seat frame 132 and the seat body 134 in a clearance area 170, as most clearly shown in the enlarged portion of FIG. 1A , The clearance area 170 is an area in which the seat base 130 is still within the delimitation area 152, but the labyrinth assembly 136 limits the movement of the seat frame 132 and the seat body 134. For example, the seat labyrinth assembly 136 may be arranged to minimize the risk of finger pinching when normal free translational movement of the seat frame 132 can result in a seat occupant's hand between the armrest portion 164 of the seat body 134 and the deep last portion 142 of the sidebar obstacle 112 is compressed. The seat labyrinth assembly 136 guides the armrest section 164 around the deep ledge section 122 along a path 172 defined by the seat labyrinth assembly 136.
    The seat labyrinth assembly 136 has a guide plate 130, a bearing block 132, and fastening means 184. The guide plate 180 is fastened to the swivel box 142 of the seat base 130, and is at least partially arranged in the delimitation area 152. The guide plate 180 defines a guide surface 186 opposite the bearing block 182 beyond an outer periphery of the swing box 142. In other words, the guide plate 180 extends an outer effective circumference of the swing box 142 so that the outer effective circumference reduces the delimitation area 152 by the clearance area 170. Instead of an interaction between the frame rail 150 and the swivel box 140 to limit a relative movement, the guide plate 180 touches the bearing block 182 as an enlargement of the outer dimensions of the swivel box 142. The guide surface 186 at least partially defines a shape of the intermediate area 170. In the present example, the boundary of the gap region 170 has the same shape as the guide surface 186.
    The bearing block 182 is fastened to the frame rail 150 opposite the guide plate 180 and extends into the delimitation area 152. The bearing block 182 has a bearing part 190, an inner part 192, and an outer part 194, which is shown in an exploded view in FIG. 3 are.
    The bearing member 190 is configured to engage the guide plate 180 to move the seat frame 132 around the clearance area 170. In the present example, the bearing part 190 is essentially cylindrical and has an axis of rotation that is substantially perpendicular to a translation plane of the seat frame 132. Therefore, the bearing member 190 rolls against the guide surface 186 to move the seat frame 132 away from the clearance area 170. In some embodiments, the bearing member 190 is missing and the bearing block 182 slides along the guide surface 186.
    The inner part 192 extends into the delimitation area 152 and has an inner flange 196 on an upper section of the inner part and opposite the frame rail 150. The outer part 150 lies opposite the inner part 192 via the rail flange 151 and has an outer flange 198 opposite the inner flange 196. Inner part 192 is attached to outer part 194 by fasteners 184 for engagement with rail flange 151. Inner flange 196 and outer flange 198 engage the top of rail flange 151 and parts 192 and 194 compress rail flange 151 together. so that the bearing block 182 is immovably attached to the rail flange 151.
    The guide plate 180 and the bearing block 182 work together to define the gap region 170. For example, when a seat occupant releases seat frame 132 from seat base 130 and moves seat body 134 to deep ledge portion 122 of obstacle 112, guide surface 186 moves bearing member 190 to cause seat body 134 to move along path 172 outside of the Space area 170 to move. The gap region 170 maintains a predetermined gap 199 between the armrest portion 164 of the seat assembly 114 and the deep ledge portion 122 of the obstacle 112. In the present example, the predetermined gap 199 is based on statistical averages for the dimensions of human fingers.
    CH 713 987 A2 Note that the actual dimensions and shapes of the bearing block 182 and the guide plate 180 may change depending on the implementation without departing from the scope of the present disclosure. For example, a length of the inner part 192 or a width of the guide plate 180 can be shortened in order to reduce the predetermined gap 199. Accordingly, the shape of the guide surface 186 can be changed to change the shape of the movement path 172.
    The embodiments described here promote free translational movement and rotation of a seat body while restricting movement of the seat body to a location that can result in contact with an obstacle.
