RU196720U1 - DEVICE FOR FIXING THE HEAD IN A CHAIR IN TRAINS - Google Patents

Abstract

The utility model relates to a device for increasing comfort on long journeys, namely, for softly fixing a person’s head in a chair, which at the same time holds its head firmly enough so that a person sitting in a chair is in a comfortable position during sleep. The device allows you to gently fix the position of the head, preventing it from moving in the horizontal and vertical planes, creating comfortable conditions for the passenger, however, it still remains possible for the head to move slightly left-right-forward-backward, i.e. it turns out a "flexible" fixation. The technical result of the claimed technical solution is achieved due to the structural design of the device in the form of two rigid brackets, a belt for placement around the person’s head and attachment to the upper part of the back of the chair, a belt with a cup to support the chin, which differs from previously known devices in that the temporal part has structural elements fastened by two supports and a pin. 6 c.p. f-ly, 5 ill.

Description

This utility model relates to a device for improving the comfort of holding the head in a chair on long journeys. More specifically, the utility model relates to a device for softly fixing the head in a relaxed state of relaxation of the muscles of the neck and throat, which is soft enough and at the same time holds the head firmly so that the person sitting in the chair is in a comfortable position.

When traveling by car, bus, train, plane or on a ship, the passenger is in the chair, so he needs comfortable conditions that allow him to sleep and do not move forward or sideways on the chair. This problem is only partially solved by changing the angle of inclination of the chair, since the position of a person in the reclined seat is not convenient enough for him.

Several examples of devices for holding the head in a chair while traveling are known in the art.

The most commonly used in everyday life are elastic or inflatable pillows in the shape of a horseshoe that are worn around the neck (for example, similar to those described in patents US 4031578, US 4617691, US 5471690, US 6135560). Their disadvantage is that they only support the head in a more comfortable position, but do not prevent it from falling sideways or forward while a person is sleeping in a chair.

Known devices that allow you to keep your head upright with various supporting structures that come in contact with it in some places. For example, the device described in the patent for utility model RU176591 “Device for improving comfort on trips” (IPC A47C 7/38, priority 09/08/2017), a belt fastened around the upper part of the back of the chair includes a bandage for the forehead made in the shape of the inverted letter "T", to which the side straps are sewn on the sides, and the upper strap is fixed on top, and the ends of all the straps are attached to each other. In the first embodiment, the ends of all belts are fastened together by a fastener in the form of a triple carbine. In the second embodiment, the ends of the side belts are fastened together by a fastener in the form of a double carabiner, while the upper belt is attached to the side with a clamp. Side and top belts can be made of tensile material. The dressing is made of soft material. The upper strap can be attached to the forehead bandage with Velcro fasteners. The disadvantage of this device is that it cannot hold a person’s head in a vertical plane, i.e. a person can slide down in a chair and then the bandage for the forehead will not have a restraining effect.

In addition, a technical solution is known from the patent for utility model RU176592 “Device for improving comfort on trips” (MPKA47C 7/38, priority 09/08/2017), containing a belt with a carabiner for attaching to the upper part of the back of the chair, a bandage for the forehead, sewn on both sides to the belt, emergency fastening in the form of Velcro fasteners, made on the belt, and retaining rings that are worn on the belt and fastened to the chair with Velcro. The belt is made of tensile material, and the bandage is made of high-quality soft material. The disadvantage of this device is also that it does not allow to prevent the displacement of the head in a vertical plane when a person crawls down in a chair.

From the patent for invention RU2532148 “Device for improving travel comfort” (IPC B60N2 / 48, priority May 27, 2010), which is a headrest for relaxing the muscles of the neck and throat of a seated person, it contains a head belt for putting on a person’s head, a seat belt for attachments to the back of the chair and a neck strap connecting the frontal part of the head belt to the seat belt. The head strap can be offset in the longitudinal direction of the neck strap. This technical solution also does not prevent the displacement of the human head in a vertical plane.

The prototype of the claimed device is the device described in the patent for utility model RU188341 “Device for fixing the head in a chair when traveling” (IPC A47C7 / 38, priority 25.11.2018). The lack of “flexible” fixation has become a drawback of this device.

The technical problem of the proposed technical solution is to create a device for holding the head in the chair when traveling, not only in the horizontal plane (preventing the head from moving forward or sideways in the chair), but in the vertical one (preventing the person from sliding down in the chair and the head is not fixed in any direction )

The technical result of the utility model is the elimination or reduction of at least one of the disadvantages of the known devices or at least the creation of a device alternative to the known devices, allowing to keep the passenger's head in a comfortable position on the trip, preventing its significant displacement in the horizontal and vertical plane while maintaining the possibility for a slight movement of the head left-right-forward-backward.

The technical result of the claimed technical solution is achieved due to the technical design of the device in the form of a rigid ring formed by two brackets around the head, and pressing them (brackets) to the upper part of the back of the seat belt. The device differs from previously known devices in that the head of the passenger is not pressed, is freely ventilated and can move inside the ring formed by the brackets in a small range (20-40 mm), which reduces neck stiffness and increases overall comfort.

The device consists of two rigid brackets (1) and (8) made of rigid plastic, with two axes (11) and (12) and a pin (9) on the bracket (1). Soft foam rubber pads (5) are glued on the inner surface of the bracket (1). Velcro is glued onto the surface of the pads (5), on which a cotton removable tape is attached, which directly touches the scalp. The thickness of the pads is about 10 mm. They are located in the frontal and temporal parts of the head, 1 pc. and one on the inside of the support (4) and serve for hygienic purposes.

To hold the device on the passenger’s head, a support (4) is used, which is a strap made of semi-rigid synthetic material (for example, polyethylene), with adjustment holes (10) along the edges and a hygienic pad (5) located in the middle on the inner surface of the support ( 4).

The pin (9) of the bracket (1) is inserted into the adjustment hole (10) of the upper support (4) on one side of the bracket (1) and in the same way the other side of the support (4) is attached on the other side of the bracket (1), forming an arc that puts on the head of the passenger. Using the adjustment holes (10), the depth of dressing of the device on the passenger’s head is regulated.

On the axis (12) of the bracket (1), the ends of the pressure belt (2) are made, made of synthetic woven material capable of stretching, or of non-stretching material with stretching inserts (3). The inside of the belt should not be slippery in relation to the skin and fabric of the chair upholstery (for example, rubber strips or dots are glued).

A belt (6) is inserted onto the axis (11) of the bracket (1), which is inserted through the chin-supporting cup (7) made of plastic. On the inner surface of the cup there is also a hygienic pad (5).

The length of the clamping strap (2) and strap (6) is adjustable with a regular buckle.

Thus, the claimed technical solution, which is a device to increase comfort on trips, allows you to control the movement of the head in the chair in the vertical and horizontal planes.
