detailed description

Example:

The structure schematic diagram of the present invention is shown in Figure 1, 2, and the seat back auxiliary device of the present invention comprises headgear 1 and backrest cushion 4, wherein pillow is housed in the headgear 1, and the bottom of headgear 1 is provided with backrest cushion 4, and backrest cushion 4 is provided with an elastic inflatable cavity, and the elastic inflatable cavity is connected to the inflatable device 9 through the air guide tube 7 . One end of the air guide tube 7 is connected to the elastic inflatable cavity of the back cushion 4 , and the other end of the air guide tube 7 is connected to the inflator 9 .

In this embodiment, one side of the headgear 1 is provided with an opening that can be inserted into a pillow. So that the headgear 1 is set on the pillow. The headgear 1 is a hollow hexahedron made of elastic material, and the other five parts of the headgear 1 are cut through, so that not only can the pillow be bound, but also leaflets can be pasted, and the pillow is hung on the train seat.

In this embodiment, the headgear 1 is also equipped with an eye mask 2, and the two sides of the eye mask 2 are equipped with an eye mask 3. The eye mask 3 can be installed lightly, and can also prevent the light from directly shining on the eyes and avoid affecting the rest of the passengers.

In this embodiment, an inflatable handle 5 is installed on both ends of the surface of the backrest cushion 4, and the inflatable handle 5 can be filled with air. The effect of the inflatable handle 5 is to buffer the unexpected impact and prevent the passenger from swinging from side to side.

In this embodiment, the inflatable cavity of the backrest cushion 4 is divided into a rear pocket 41 for a headgear 1 and a front pocket 42 for a fully deflated inflatable handle 5 . The above-mentioned inflatable cavity is divided into a front pocket 42 and a rear pocket 41 by the cloth bag through a sewing method. When the present invention is not in use, the headgear 1 and the inflation handle 5 are packed into the rear pocket 41 and the front pocket 42 respectively.

In this embodiment, a plurality of air-filled elastic protrusions 6 are installed on the surface of the backrest pad 4 . The elastic bosses 6 filled with air communicate with each other and can maintain the same pressure under pressure. The function of the elastic bosses 6 is to make the human body lean on the elastic bosses more comfortably.

In this embodiment, the elastic protrusions 6 installed on the surface of the backrest pad 4 are cylindrical protrusions, and the elastic protrusions 6 can be evenly distributed on the back and neck, and the elastic protrusions 6 provided on the neck are in the form of A certain concave shape, corresponding to the curved structure of the neck.

In this embodiment, the materials of the back cushion 4, the air duct 7, the inflatable handle 5 and the elastic post 6 are all nylon, which is waterproof and heat-resistant.

In this embodiment, the inflatable device 9 is an inflatable air bag or an inflatable cylinder. The inflation device 9 is connected with the control switch 8, and the inflation device 9 controls the inflation and deflation of the seat back auxiliary device through the control switch 8.

In this embodiment, the headgear 1 is made of elastic material, and since the material of the headgear 1 has certain elasticity, the height can be adjusted to suit passengers of different heights.

The working principle of the present invention is as follows: when in use, the headgear 1 and the inflator 9 are taken out from the rear pocket 41 and the front pocket 42 respectively, and the headgear 1 is placed in a position suitable for passenger's head support. Inflate the hollow cavity in the back cushion 4 through the inflator 9 and the air duct 7 . Place the inflated seatback assist device on the back and secure it.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: it can still record the foregoing embodiments Modify the technical solution, or replace some of its technical features; and these modifications or replacements do not make the technical solution itself deviate from the spirit and scope of the technical solution of the present invention.
