Headrest device for a subway seat

technical field

The invention relates to a seat device, in particular to a headrest device for a subway seat.

Background technique

At present, the subway is basically in order to meet people's travel needs, taking as many passengers as possible as the starting point, rather than paying much attention to the comfort of riding. Based on this, most of the seats on the subway are arranged in a row, and there is basically no gap between two adjacent seats. The seats are neither equipped with armrests nor headrest devices, which are helpful to save space. the design of. However, for office workers, it is certainly hoped that these seats can be configured with facilities similar to the headrest device, so that people can take a short rest when they are tired.

Contents of the invention

Aiming at the above-mentioned technical problems, the present invention designs and develops a headrest device for subway seats that is convenient to use and takes up little space. In addition, the headrest devices of two adjacent seats can cooperate with each other to form a belt-like belt. The structure can restrict children from running in the subway car.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

As shown in Figures 1 and 2, the present invention provides a headrest device for a subway seat, comprising: a vertically extending elongated groove 1, which is formed on a wall 15 of a subway car and is located on the side of the subway seat. One side of the backrest part 13; the base 4, which is arranged in the inside of the groove 1, close to the upper edge of the backrest part 13; the support body 3, which is rod-shaped, is accommodated in the groove 1 , one end of the support body is rotatably arranged on the base 4 in a plane perpendicular to the backrest part, and the front part of the support body 3 is wrapped with a layer of elastic material, so that the The front part of the support body forms a headrest part 2; and the limiting part 5, which is arranged below the base, is located on the rotation path of the support body 3, and when the support body turns downward, the The supporting body is kept in a horizontal state; wherein, a torsion spring is also arranged between one end of the supporting body and the base.

Specifically, when needs are used, the support body 3 is rotated downward until it is placed in a horizontal state (that is, a state perpendicular to the wall of the subway car, and the passenger can rest the headrest against the headrest part 2. The headrest device It is set between two adjacent seats. When the support body 3 is opened, it will not interfere with the adjacent passengers; the base 4 should be close to the upper edge of the backrest part to facilitate the passengers to lean on. The support body A torsion spring is arranged between one end of 3 and the base 4. When the support body is not used, the support body will rise slowly under the action of the torsion spring and return to the initial position, that is, the entire support body is accommodated in the groove.

Groove 1 can be directly opened on the subway car wall 15; it can also be opened on a separate part, and then the part is fixed to the subway car wall. The advantage of doing this is that it is more convenient to improve the subway, and the transformation cost Low.

As shown in Figure 3, in the described subway seat headrest device, the support body 3 includes a support body main body and an inner rod, the middle part of the support body main body is provided with a through hole 8, and the inner rod 12 Slidably arranged in the through hole 8, the free end of the main body of the support has an annular stopper 14, so that the diameter of the end portion 9 of the through hole 8 is compared with the main body of the through hole 8 Partially reduced, the diameter of the main part of the inner rod 12 is consistent with the end part 9 of the through hole, the diameter of the end part 10 of the inner rod is consistent with the main part of the through hole, the end of the inner rod The site 10 is connected to the bottom of the through hole by a spring 11; the inner rod includes a first inner rod part 7 and a second inner rod part 6, one end of the first inner rod part 7 and the second inner rod One end of the part 6 is pivotally connected, and the other end of the second inner rod part 6 is provided with a buckle part 16; the second inner rod parts of two adjacent seats are buckled together by a pair of buckle parts. Wherein, the diameter of the end portion 10 of the inner rod 12 is consistent with the main part of the through hole 8, so as to prevent the inner rod from detaching from the through hole; the end portion 10 of the inner rod is connected to the bottom of the through hole by a spring 11, so that the inner Rod reset. Specifically, when used as a waist belt, the support bodies of the headrest devices of two adjacent seats are simultaneously opened, the two support bodies 3 are in a state parallel to each other, and then the inner rods of the two support bodies are drawn out, wherein The second inner rod part of one support body is bent from the right side, the second inner rod part of the other support body is bent to the left, and the two second inner rod parts are buckled together by the buckle part 16 . Here, the buckle component can be a commonly used structure for buckling, such as a snap-in buckle, wherein one second inner rod part is provided with a male component, and the other second inner rod part is provided with a female component, and another example is two second inner rod parts. The two inner rod parts are respectively provided with a socket and a buckle, and the buckle can be inserted into the socket to realize the connection. When the passenger has a child, then a temporary child seat can be constructed, and the two headrest devices cooperate with each other to form a structure similar to a waist belt.

In the headrest device for subway seats, the support body 3 is cylindrical. In order to increase the comfort of the headrest part, the support body 3 is set in a cylindrical shape, and the headrest part 2 is also cylindrical.

In the headrest device for a subway seat, the limiting component 5 is a limiting block protruding horizontally outwards, and the upper part of the limiting block has a bearing surface in a circular arc shape. The rear portion of the supporting body is just positioned at the top of the limiting block, and is limited by the limiting block so as not to rotate downwards.

The headrest device for a subway seat further includes: a pair of clamping parts, respectively located on both sides of the groove, facing each other and clamping the support body in the middle. In order to prevent the supporting body from falling suddenly when severe vibration occurs, clamping parts are provided to fix the supporting body. The clamping parts can also adopt structures in the prior art, such as sockets and buckles.

In the headrest device for subway seats, the limiting component 5 is fixed in the groove 1 . In order not to affect the aesthetic appearance of the subway car wall, the limiting part is also arranged in the groove so that it does not protrude from the subway car wall.

Although the embodiment of the present invention has been disclosed as above, it is not limited to the use listed in the specification and implementation, it can be applied to various fields suitable for the present invention, and it can be easily understood by those skilled in the art Therefore, the invention is not limited to the specific details and examples shown and described herein without departing from the general concept defined by the claims and their equivalents.
