Specific embodiment

The seat extension board that mode one, i.e. band add backrest 3.As shown in Figure 1, the seat extension board is extended by front support 5 Seat board 4 and additional backrest 3 form, and the upper end of front support 5 hingedly or is fixedly connected with the front end of extension seat board 4, add backrest 3 Lower end and the rear end for extending seat board 4 are hinged.

As shown in Fig. 2, a submode of which is to be equipped with additional backrest hook behind the top for adding backrest 3 7, additional backrest hook 7 in short transverse be it is adjustable, to adapt to the backrest 2 of different height.

When not used, which can be folded up.

In use, by fold open, by additional backrest hook 7(if any) hang over existing seat 1 backrest 2 it is upper End, the rear end for extending seat board 4 are seated on seat cushions, and front end arises from ground by front support 5, for extending seat board 4 Hinged situation with front support 5, after seat extension board is opened, folding support rod 6 is stretched so that front support 5 and extend seat board 4 at Fixed angle.

Mode two, i.e. the simplification version of mode one, as shown in figure 3, which and mode one the difference is that, without adding backrest 3, extend the rear end of seat board 4 by extending seat board hook 12, catches on the lower part of backrest 2, after preventing people from taking, people's When back is close to backrest 2, extend seat board 4 toward front slide.

The left and right sides for extending seat board 4 respectively installs an extension seat board hook 12；Extend seat board hook 12 and extends seat board 4 Hinged end puts in the inside of free bearing pipe 11, and can stretch in left and right directions along free bearing pipe 11, to realize the extension of the left and right sides Seat board links up with the adjusting of 12 relative widths, from the pick-and-place on existing seat 1 and adapts to different width with Convenient chair extension board Existing seat 1.

One submode of which is to be substituted to extend seat board hook 12 with rope, i.e., lies in rope under backrest Portion, to prevent 4 forward slip of extending seat plate.

Mode three, the i.e. further simplified plate of mode two, as shown in figure 4, which replaces extending seat board with backing pin 14 Hook 12, this mode, which is suitable for existing seat 1, the case where handrail strut 13.

Backing pin 14 from the pick-and-place on existing seat 1 and can also be adapted to different along its axial stretching with Convenient chair extension board The existing seat 1 of width.

In order to adapt to the different location of handrail strut 13, as shown in Figure 5 and Figure 6.The rear portion of extension 4 two sides of seat board has multiple Backing pin fixation hole 15.

One submode of which is to substitute backing pin 14 with rope, i.e., lies in rope on handrail strut 13, to prevent Extend 4 forward slip of seat board.

In the case of it is hinged for extending seat board 4 and front support 5, in order to adapt to existing seat 1 cushion different height, There are multiple folding support rod fixation holes 16 in the front for extending 4 two sides of seat board.
