     Example embodiments are described more fully hereinafter with reference to the accompanying drawings; however, since the drawings are shown for clearly describing and supporting the specification of the present invention, they may not in real proportional scale or with precise arrangement. Therefore, they may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey exemplary implementations to those skilled in the art. 
     Referring to the related drawings, the following description will disclose some example embodiments of an arm structure and an aircraft seat assembly of the present invention. For clarification and understanding, like reference numerals refer to like elements throughout. 
     Referring to  FIGS. 1 and 2 , they illustrate a first schematic and a second schematic of a first embodiment of an aircraft seat assembly according to the present invention. The aircraft seat assembly  100  includes an arm structure  10  of the present invention, which is used for passengers putting their hands appropriately. 
     As shown in  FIGS. 1 and 2 , the aircraft seat assembly  100  includes an arm structure  10  and an aircraft seat  20 . The amount of the aircraft seat  20  may be two, three or more, and the amount of the arm structure  10  may be corresponding one, two or more. In this embodiment, the present invention uses two aircraft seat  20  and one arm structure  10  as an example. However, it cannot be used for limiting the present invention 
     The two aircraft seats  20  are located adjacently. The arm structure  10  includes an arm body  101  and two supporting boards  102 . The arm structure  10  is set between the two adjacent aircraft seats  20 . The two supporting boards  102  are shaped corresponding to the arm body  101 , and pivotally connected to two sides of the arm body  101  respectively. Each of the two supporting boards  102  has a first position A and a second position B. 
     As shown in  FIG. 1 , when the two supporting boards  102  are in the first position A, the two supporting boards  102  are integrated with the arm body  101  harmoniously to form an arm in normal shape. As shown in  FIG. 2 , when the two supporting boards  102  are in the second position B, the two supporting boards  102  are perpendicular to the arm body, for supporting hands of passengers seated on the two aircraft seats  20 . 
     Furthermore, the arm body  101  is in a T shape from a top view. That is, the arm body  101  includes two recess portions from a top view, wherein the two supporting boards are set within the recess portions. Therefore, when the two supporting boards  102  are in the first position A, the two supporting boards  102  can be filled in the recess portions of the arm body harmoniously, and the two supporting boards  102  can accordingly be integrated with the arm body  101  to form an arm not suddenly. 
     On the other hand, an end of the supporting board  102  and a side of the supporting board  102  near the arm body  101  are pivotally set within the recess portion  1011 , and the side of the supporting board  102  is near seat cushion  201  of the aircraft seat  20 . Therefore, the passengers seated on the aircraft seat  20  can turn the supporting board  102  to the direction of the seat cushion  201  of the aircraft seat  20 , so that the supporting board  102  is rotated from the first position A into the second position B. Thus, the passengers seated on the aircraft seat  20  can put their hands on the supporting board  102  comfortably. 
     Referring further to  FIG. 3 , it illustrates a third schematic of the first embodiment of the aircraft seat assembly according to the present invention. As shown in  FIG. 3 , when the two supporting boards  102  are in the second position B, the two supporting boards  102  and the arm body  101  are integrated in a reverse T-shape from a cross-sectional view at an end of the arm body  101 . Therefore, the passengers seated on the aircraft seat  20  and on both sides of the arm structure  10  can put their hands on the supporting board  102  respectively, and the arm body  101  can naturally be a partition board for preventing hands of the passengers from touching each other. By way of the design of the present invention, the problems of un-purposely touching hands which bothered the passengers can be resolved. 
     By the way, the techniques used for the supporting board  102  pivotally set within the recess portion  1011  can be any ones town by skilled in the art. For example, it can be a method of using a hinge for prior flip electronics devices or using a cylinder lodging in a circular hole. When using the method of a cylinder lodging in a circular hole, it is preferred that an engaging part is used to preventing the supporting board  102  from suddenly or unexpectedly rotating between the first position A and the second position B. The engaging part can work by interference between two parts or engagement. For example, the engaging part, such as a protrusion, can be set on the walls of the recess portion  1011  and a pit is set on the walls of the supporting board  102 , so that the supporting board  102  can be engaged in the first position A when the protrusion engages the pit. Or, the engaging part, such as a hook, can be set on the walls of the recess portion  1011  and a groove is set on the walls of the supporting board  102  corresponding to the hook, so that the supporting hoard  102  can be engaged in the first position A when the hook engages the groove. 
     Referring to  FIGS. 4 and 5 , they illustrate a first schematic and a second schematic of a second embodiment of an aircraft seat assembly according to the present invention. In this embodiment, some components are the same and need not described anymore. The major difference between the second embodiment and the first embodiment is that the supporting board  102  is rotated from the first position A into the second position B. 
     Further, in accordance with the second embodiment, the width of the supporting board  102  is less than the width of the arm body  101 . In addition, an end of the supporting board  102  and a side of the supporting board  102  near the arm body  102  are pivotally set within the recess portion  1011 , wherein the side of the supporting board  102  is opposite to the seat cushion  201  of the aircraft seat  20 . 
     Therefore, the passengers seated on the aircraft seat  20  can rotate the supporting board  102  forward or backward with respect to the seat cushion  201  of the aircraft seat  20 , so that the supporting board  102  can be rotated between the first position A and the second position B. The two supporting hoards  102  and the arm body  101  are integrated in substantially a reverse T-shape from a cross-sectional view at an end of the arm body  101 . The passengers seated on the aircraft seat  20  and on both sides of the arm structure  10  can put their hands on the supporting board  102  respectively, and the arm body  101  can naturally be a partition board for preventing hands of the passengers from touching each other. By way of the design of the present invention, the problems of un-purposely touching hands which bothered the passengers can be resolved. 
     Referring to  FIG. 6 , it illustrates a schematic of a third embodiment of an aircraft seat assembly according to the present invention. In this embodiment, some components are the same and need not described anymore. The major difference between the third embodiment and the first embodiment is that the supporting board  102  is rotated from the first position A into the second position B. And the difference between the third embodiment and the second embodiment is that the two supporting boards  102  and the arm body  101  are integrated in a T-shape from a cross-sectional view at an end of the arm body  101 , after the supporting board  102  rotating from the first position A into the second position B. 
     In this embodiment, the width of the supporting board  102  can correspond to or equal to the width of the arm body  101 . In addition, an end of the supporting board  102  and a side of the supporting board  102  near the arm body  101  are pivotally set within the recess portion  1011 , and the side of the supporting board  102  is opposite to the seat cushion  201  of the aircraft seat  20 . 
     Therefore, the passengers seated on the aircraft seat  20  can turn the supporting board  102  to or back to the seat cushion  201  of the aircraft seat  20 , so that the supporting board  102  can be rotated from the first position A into the second position B. The two supporting boards  102  and the arm body  101  are integrated in substantially a T-shape from a cross-sectional view at an end of the arm body  101 . That is, the turned supporting board  102  on the second position B will be on the same plane with the top surface of the arm structure  10 . The passengers seated on the aircraft seat  20  and on both sides of the arm structure  10  can put their hands on the supporting board  102  respectively, and the arm body  101  can naturally be a partition board for preventing hands of the passengers from touching each other. By way of the design of the present invention, the problems of un-purposely touching hands which bothered the passengers can be resolved. 
     Therefore, according to the preferred embodiments of the present invention, there are extra spaces provided outside both sides of the arm structures  10 , so that the passengers seated on the aircraft seat  20  and on both sides of the arm structure  10  can put their hands on the supporting board  102  respectively, and the extra spaces can be used for preventing hands of the passengers from touching each other. By way of the design of the present invention, the problems of un-purposely touching hands which bothered the passengers can be resolved.
