Fig. 2 and 3 are further views of the structure of the components of the present invention based on fig. 1. As shown in fig. 2, a composite structure of the components is described; as shown in fig. 3, an exploded view of the components of fig. 2 is depicted.

The front cross beam 14, the rear cross beam 16 and the limiting body 24 on the seat frame 20 on the base 10 are located in the same plane, the limiting body 24 is located between the front cross beam 14 and the rear cross beam 16 and used for limiting the distance of the forward or backward movement of the seat frame 20, when the seat frame 20 reaches the foremost position forward, the front cross beam 14 blocks the limiting body 24 from further moving forward, and further limits the seat frame 20 from further moving forward, at this time, the backrest frame 30 is in a state of maximum inclination (for example, 30 degrees) of backward tilting, when the seat frame 20 reaches the rearmost position backward, the rear cross beam 16 blocks the limiting body 24 from further moving backward, and further limits the seat frame 20 from further moving backward, and at this time, the backrest frame 30 is in an upright (0 degree) state.

The guide rail 50 includes: the seat frame 20 comprises a convex strip 52, a groove 54, two convex strips 52 are respectively and fixedly connected with the left side and the right side of the seat frame 20, two grooves 54 are respectively and fixedly arranged on the left inner side and the right inner side of the base 10, the convex strips 52 are matched with the grooves 54 and can slide forwards or backwards, and then the seat frame 20 can slide forwards and backwards relative to the base 10.

FIG. 4 depicts the structure of latch 60. The latch 60 includes: j-shaped iron 62, latch 64, spring 68, button 66; the rib 52 of the corresponding rail 50 is provided with a bayonet 56 (in the figure, the rib 52 is cut away to better show the structure of the latch 60). The J-shaped iron 62 is disposed in the base 10 to be movable up and down. One end of the J-shaped iron 62 is provided with a latch 64, the latch 64 is matched with the bayonet 56, when the latch 64 is meshed with the bayonet 56, the latch 60 is in a locking state, the guide rail 50 cannot slide back and forth, so that the seat framework 20 is fixed on the base 10, and when the latch 64 is separated from the bayonet 56, the latch 60 is in an unlocking state, the guide rail 50 can slide back and forth, so that the seat framework 20 can be pushed to move back and forth. A spring 68 is arranged below the J-shaped iron 62, and the J-shaped iron 62 is pressed upwards to enable the latch 64 and the bayonet 56 to be in an engaged state. The other end of the J-shaped iron 62 is provided with a button 66, the button 66 is exposed from the base 10, and when the passenger presses the button 66, the J-shaped iron 62 moves downward, and the latch 64 and the bayonet 56 become disengaged against the spring 68.

Fig. 5 is a bottom view illustrating the structure of the table 70 and related components. The table board 70 includes: an upper magnetic strip 72, a front limit salient point 74 and a rear limit salient point 76; correspondingly, the telescopic rod 80 comprises: a lower magnetic strip 82, a limit pit 84 and a head 86. The telescopic rod 80 is sleeved in the handrail 18 and can extend forwards for a certain length. When a passenger needs to use the telescopic rod, the desk plate 70 is buckled on the telescopic rod 80, at the moment, the upper magnetic strip 72 and the lower magnetic strip 82 are matched and mutually attracted, the front limiting salient points 74 are buckled in the limiting concave pits 84, the two rear limiting salient points 76 are limited on the inner sides of the two handrails 18 and can only move back and forth, and the front edge of the upper magnetic strip 72 is clamped with the head 86 of the telescopic rod 80.

Fig. 6 illustrates a placement method of the desk board 70 when it is not in use, and the desk board 70 can be leaned against the back of the front seat by arranging the magnet 78 on the desk board 70 and arranging the magnet 78 at the corresponding position of the front seat base 10 and matching. A shelf placement table 70 may be provided under the base 10 of the main seat or the front seat. For simplicity of illustration, the table 70 of both placement methods is placed in the same figure.

Fig. 7 is a sectional view illustrating the upright state of the back frame 30.

The backrest frame 30 is in an upright state, and the seat frame 20 and the connecting shaft 26 are already in the rearmost position because the rear cross member 16 blocks the stopper body 24 from further rearward movement; the passenger can sit on the seat with the table board and can lie on the seat with the table board.

Fig. 8 is a sectional view illustrating a state of maximum inclination (e.g., 30 degrees) of the back frame 30.

The backrest frame 30 is in the maximum inclination (for example, 30 degrees) state, because the front cross beam 14 blocks the limiting body 24 from further moving forward, the seat frame 20 and the connecting shaft 26 are already in the most front position; the passenger can lie on the seat with the desk plate in a reclining way. The utility model discloses in, support position 34 is located 1/4 high department of back skeleton 30, and when the lower extreme of back skeleton 30 removed, the upper end of back skeleton 30 can remove equal distance to opposite direction, through occuping this seat and back row same space, and this seat has shared the influence that back skeleton 30 slope caused jointly with the back row passenger. The backrest frame 30 is inclined to occupy more transverse space, occupy the seat or occupy the rear row, and the supporting position 34 can be arranged between the heights 1/3 to 1/5 of the backrest frame 30 according to actual needs, but the more the supporting position is larger than 1/3, the more the space occupied by the seat is, the discomfort of the passenger can be caused, and the less the supporting position is in 1/5, the more the space occupied by the rear row is, the discomfort of the passenger can be caused.

The passenger can sit on the reclining seat with the table, the latch 64 is disengaged from the latch 56 by pressing the button 66 of the latch 60, the latch 60 is unlocked, then the passenger's feet are landed to exert a force to push the seat frame 20 to move back and forth, thereby adjusting the backrest frame 30 to a proper inclination angle to meet his or her own needs, and finally, the button 66 of the latch 60 is released to fix the seat frame 20 to maintain the inclination angle of the backrest frame 30. The passenger can also stand on the seat side with the desk board which can be reclined, press the button 66 of the latch 60 with one hand, and push the seat frame 20 to move back and forth with the other hand, thereby realizing the adjustment of the inclination angle of the backrest frame 30.

Fig. 9 illustrates the utility model discloses a contrast with current seat under the state of lying to one side, the shadow part is for taking the space of back row in the picture, under the same angle condition that realizes that the seat leans backward, the utility model discloses a back skeleton 30 has only moved backward the distance of half of current seat, takes 1/4 of only current seat between the back evacuation to effectively slow down the uncomfortable of back row passenger.
