Description

[Detailed description of the device]

[0001]

[Use in industrial fields]

 The present invention has an object to prevent the seat occupant's head from swinging left and right by being formed into a desired shape by air filling and detachably attached to the head abutting portion of a vehicle seat or a chair back. The present invention relates to a portable headrest.

[0002]

[Prior Art]

 Conventionally, as a headrest that is portable for such a purpose, there is a simple portable pillow for a chair (utility model application No. 182959 in 1987) previously disclosed. In this device, as shown in FIG. 6, one air bag c having an air injection plug b is arranged and fixed on each side of the head contact pad a, and the head contact pad a is formed into an elastic loop-shaped bed. Alternatively, it was attached to the head joint part e of the seat back with a string d.

[0003]

[Problems to be solved by the device]

 However, since the simple portable pillow for a chair having such a structure is attached by a loop-shaped rubber belt or the like and is held on the backrest only by this elastic force, the fixing force is insufficient. For this reason, when the head is frequently attached to the seat of a vehicle where it sways in the left-right direction, the pillow itself may slide to the left or right, and the purpose of preventing left-right swaying of the head may not be fully exerted. It was

[0004] The air bag for supporting the head side portion also inflates left and right due to injecting air into each of the air bags, so that the air bag sometimes does not exhibit a sufficient supporting force. Therefore, the present invention solves such a problem, and aims to provide a portable headrest that is more portable and has more reliable supporting force of the temporal region and fixing force of the headrest to the backrest. To aim.

[0005]

[Means for solving the problem]

 In order to achieve the above object, the present invention is configured as follows. In a headrest that is detachably attached to the head abutting portion of a vehicle seat or a backrest of a chair, a belt-like holding base body having seat fixing means attached to both ends is provided, and it can be attached to a substantially central portion of the holding base body. The occipital region pad, which is made of a flexible material and is expanded and shaped like a pillow by air filling, is placed and fixed, and the flexible pad made of a flexible material is adjacent to both sides of the head pad and is convexly expanded forward by air filling. Place and fix the temporal support pad that is shaped to cover the head. Then, the air chamber in the occipital pad and the air chambers in the both head support pads are communicated with each other, and an air injection plug is provided at any one position.

The seat fixing means may be a hook that allows the seat fixing means to be adjusted in the front-rear direction according to the thickness of the seat backrest and to hold the backrest side portions so as to be clamped. .. Further, one or more pressure bonding pads that are expanded and molded by air filling are arranged in the holding substrate, and the air chambers in the pressure bonding pads are communicated with the air chambers in the occipital region mat and both head pads. Alternatively, the configuration may be changed.

Furthermore, the seat fixing means is a fixture in which a long plate-shaped member is bent in a substantially inverted U shape, and is slidably attached to a front position member of the fixture, and an end of a holding base. It may be composed of a slinging piece whose length is adjustable.

[0008]

[Action]

 With this configuration, when the portable headrest of the present invention is used, air is first injected from the air injection plug to expand and mold each pad into a predetermined shape. Then, attach it to the desired position of the head abutment of the seat back. For this attachment, the belt is looped around the backrest side, the length is adjusted, and the belt is tightened. In the case of hooks, the hooks are hooked by adjusting the length of the hooks in the front-rear direction according to the thickness of the seat back so as to clamp the side of the seat.

The seated person uses the back head pad by leaning the back head. If the head sways to the left or right, it will be supported by the bilateral head support pads and the head will remain stable.

[0010]

【Example】

 Next, a specific example of the above configuration will be described below with reference to the drawings. FIG. 1 is a perspective view showing the whole of this embodiment. FIG. 2 is a front view showing a part of each pad from the front side, and FIG. 3 is a plan view showing a state of being mounted on a seat from the top side.

The holding base 1 is made of a flexible material such as soft resin, cloth, or leather, and is formed in a strip shape, and its length is set so that it can go around the lateral circumference of the seat back. The occipital region pad 2 is arranged and fixed in the center of the occipital region at a position where the occipital region abuts when the seat back is attached. The occipital region pad 2 is made of a flexible material such as a soft resin and is composed of one or more air chambers 2a, 2b, 2c having a hollow inside, and is expanded in a pillow shape by air filling. .. Here, the shape of the lowermost air chamber 2c may be protruded forward from the other occipital region pad 2 so as to form a neck pad that partially abuts the neck of the seated person. As a result, the head can be held more reliably, and the volume to be pressed can be increased to further exert the action described below.

On both sides of the occipital region pad 2 of the holding substrate 1, temporal region supporting pads 3, 3 are arranged and fixed adjacent to the occipital region pad 2. The side head support pad 3 is formed of a flexible material, and has a shape that expands in a forward convex shape by air filling to cover the side head. Further, a plurality of pressure pads 4, 4, ..., Each of which is an air chamber that expands due to air filling, are arranged and fixed to the holding base 1 along the length direction.

The insides of the occipital region pad 2, the side head supporting pad 3, and the pressure bonding pad 4 are connected to each other by a communication pipe 5 so that air can move freely. An air injection plug 6 for injecting air is attached to any one of these pads. Further, the pressure bonding pad 4 may be arranged and fixed over the entire circumference of the holding substrate 1 in a loop shape. With such a configuration, after the seat backrest is mounted so as to be covered, air can be injected to expand the seatback so as to increase the fastening force. By thus communicating the insides of the pads 2, 3, 4 with each other, when the seated person leans back and presses the occipital region pad 2 with the head 17, the pressing force of the occipital region pad 2 is passed through the communicating pipes 5 to the other pads 3 respectively. It is transmitted to the inside of 4, and the expansion force increases. This rise in the expansion force increases the shape-retaining force and strengthens the elasticity in the temporal support pad 3, thus ensuring the support of the head, and in the crimping pad 4, the seat back of the holding base 1 is seated. The frictional force with the surface increases, making it less slippery and increasing the tightening force.

Next, seat fixing means is attached to both ends of the holding base 1. This seat fixing means may be a method in which a buckle is attached to a general belt and can be fixed at an appropriate length, and as shown in the figure, a so-called surface fastener (trade name "Magic Tape") 18 is used. You may use. As a result, an appropriate seat back width can be accommodated.

Furthermore, as shown in FIGS. 4 and 5, hooks 8 hooked on the seat back side surface 7 may be attached to both ends of the holding base 1. The hook 8 has a substantially U-shape, and a substantially L-shaped front member 8a to which the end piece 1a of the holding base 1 is attached by adjusting the length thereof, and a slidable member on the front member 8a. The rear member 8b has a substantially L shape and is attached to the rear surface of the seat back. The front member 8a is formed with a slide groove 9 that is open to the side surface, and notches 10 that engage only in one direction (arrow a) are formed continuously at regular intervals above and below the inside of the groove. There is. Into the slide groove 9, a rear member 8b having a notch 10 hooked on the notch 10 formed on the upper and lower sides of the tip is slidably fitted. A front end portion of the rear member 8b is formed in a substantially U shape, and operation convex pieces 12, 12 protruding laterally are integrally formed at opposite ends of the tip end portion.

With this configuration, the hook 8 is operated as follows. By pushing the rear member 8b along the slide groove 9 of the front member 8a (arrow b), the interval between the hooks 8 can be adjusted according to the thickness of the seat back. At this time, due to the action of the notch 10 and the claw 11, the movement of the rear member 8b in the direction of arrow b is free, but conversely the movement in the direction of arrow a is restricted. This limitation is lifted by pinching the opposed operating projections 12 with a finger or the like in a direction (arrow c) that narrows the space to bend the substantially U-shaped tip and separate the claw 11 from the notch 10. To be done.

Next, as shown in FIG. 6, another seat fixing means may be arranged. A slidable tool 13 is attached to the end piece 1a of the holding base 1 so that the length can be adjusted. The slidable tool 13 is made of a long plate-shaped member such as a metal material or a hard resin material in a substantially inverted U shape. It is slidably mounted on the front position member 14a of the mounting tool 14 which is bent. Engagement recesses 15 are formed at appropriate intervals on the front surface of the front position member 14a, and engagement protrusions (not shown) formed on the inner surface of the slide tool 13 engage with the engagement recesses 15. As a result, the slide tool 13 can be held at an appropriate position.

Such a fastening means is especially for use on the backrest of the back seat of a motor vehicle. That is, the insertion tongues 14b of the rear-position members of the attachments 14 attached to both ends of the holding base 1 straddle the upper ends of the rear seat backrests 16 at appropriate intervals and are provided in the gaps in the back of the backrests. Insert and fix. Then, by appropriately moving and setting the position of the slinging tool 13, it can be used by adults and children with significantly different sitting heights.

It should be noted that although the attachment 14 is arranged to straddle the upper end of the backrest of the rear seat, it is not limited to this and may be attached to the front seat in the same manner.

[0020]

【effect】

 With the above configuration, the present invention has the following effects. By mounting it on the seat of a vehicle such as a car, train, airplane, or the back of a chair with a high back, the temporal support pad securely supports the sway of the head of the occupant and holds it stably. Therefore, it is possible to maintain a comfortable state even during sleep.

The present invention is suitable for being carried because it can be miniaturized by folding because it is used by forming it into a predetermined shape by filling air from the air injection plug. In addition, since the occipital region pad is provided, and the structure is such that the occipital region pad and the pressure pad are connected to each other, the compression of the occipital region pad is transmitted to each pad, and the temporal support pad has an increased supporting force. With the crimp pad, it exerts the effect of increasing the fixing power to the seat back.

Further, when the notch type is used to adjust the front-back direction according to the thickness of the seat back and the hook for holding the backrest side is used as the seat fixing means, the seat is securely attached and There is an advantage that the holding base can be prevented from shifting in the left-right direction and the temporal region can be reliably supported. Furthermore, by forming the insertion tongue piece and using the substantially U-shaped attachment tool as the seat fixing means, it can be used for the back seat backrest, and by moving the sliding tool up and down, It can also be applied to children.
