Description

A HEAD RESTRAINT

BACKGROUND The invention relates to head restraints for a person in seated position. Travel comfort in longer journeys by car, bus, train or plane is important, as the travellers spend most of the travelling time seated in a chair. Passengers often seek for a comfortable seating position that would allow the person to dose or sleep. In the upright seating position the head may easily fall to one side or forward, causing pain or unpleasant sensation which may lead to waking up. U-shaped travel pillows are one known solution for stabilizing the head and neck for sleeping in an upright position. For some persons the feeling of U- shaped pillow may be uncomfortable, causing the feeling of choking.

One solution utilizes a hat and a series of attached hook-and-loop connector straps to secure the hat to the headrest of vehicle’s seat. The solution does not allow for movement. The neck may not be sufficiently or comfortably supported, and the spine may become out of alignment. It is not comfortable to sit or sleep in the fixed position as slight movements may improve blood circulation and prevent numbness. It is desirable to be able to turn one's head or the upper part of the body and be able to shift back and forth in the seat.

SUMMARY S 25 This summary is provided to introduce a selection of concepts in a simplified 2 form that will be further described below in the detailed description. This 2 summary is intended to neither identify key features or essential features of the N claimed subject matter nor to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all of the disadvantages noted in any part of this disclosure.

A head restraint comprises a headband that is connected to the headrest of a seat with four loose straps.

A person sitting and/or travelling in a seated position wears the headband or a cap having the headband.

The headband or the cap having the headband distribute the supporting forces around the head.

The cap, hat or beanie may be provided as complementary item during a long flight, carrying for example airline company logo, travel agency logo, colour or any other brand identifier.

The headband, cap, hat or beanie may be user's personal item that engages to the head restraint system installed in the seat.

Selected components of the head restraint or the head restraint system may be furnished by the vehicle operator or the passenger.

The head restraint is connected to the headrest or to the upper portion of the seat where the user is sitting.

Two of the four straps are attached to the same side of the headrest, for example to the left side.

One strap is connected to the left side of the headband, while the other strap is connected to the right side of the headband.

Similar structure with the remaining two straps is arranged on the right side of the headrest.

When the user, while wearing the headband, leans his/her head to right, one strap from both sides of the headrest tighten - the first strap connected between the left side of the headrest and the left side of the headband, and the second strap connected between the right side of the headrest and the left side of the headband.

This secures the head in slightly leaning upright position, face > forward.

Similarly, the remaining two straps may loosen.

When leaning the head N 25 left, the opposite straps tighten.

Different leaning positions cause different 2 combinations of straps to be tightened. > The support structure provides at least triangular lateral support for the head, E allowing natural neck movement on leaning to both sides.

The four-vector & solution does not twist the head while leaning to either side, as the crossing > 30 strap counters the rotational force of the strap tightening on the same side. - When the head leans forward, all four straps may tighten simultaneously.

The transition between the left and right lean is comfortable and natural, but restrained, as it allows natural alignment for the neck. The user may set the straps to desired tightness, selecting the amount of free movement. The head restraint helps passengers to sleep or rest during travel, as the convenient support solution mitigates stress to the neck and reduces the risk of numbing or pain in the neck. The head may be secured firmly into the desired position or it may be allowed for some free movement. With at least two straps tightened, the head does not experience swaying effect as could happen in one contact point per side. Other applications are patient transport, wherein patient's head may be secured to the transport device. As one example, a wheelchair may be equipped with the head restraint system. Many of the attendant features will be more readily appreciated as they become better understood by reference to the following detailed description considered in connection with the accompanying drawings. The embodiments described below are not limited to implementations which solve any or all the disadvantages of known head restraints.

DETAILED DESCRIPTION The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. However, the same or any equivalent functions and sequences may be accomplished by different examples. Although the present examples are described and illustrated herein as being implemented in a bus seat, the head restraint described is provided as an example and not a limitation. As those skilled in the art will appreciate, the present examples are suitable for application in a variety of different types of seats, such as plane seats, train seats or office seats. FIG. 1 illustrates schematically one exemplary embodiment of the head restraint when a person is sitting on a seat, for example on a bus seat. The seat comprises headrest 12. In the example person's head 10 is leaning on the O headrest 12. A seat fastener 11 connects the head restraint to the seat. In this N example the seat fastener 11 is a strap wrapped around the headrest 12. 3 Alternatively, or in addition, the seat fastener 11 may comprise other fastening = 25 means for connecting to the seat or headrest 12. The seat fastener 11 may be E fixedly attached to the seat or headrest 12. Both sides of the seat or headrest N 12 may comprise buttons, magnets or similar fastening means for removably io connecting the seat fastener 11. In some embodiments the seat fastener 11 is > easily removable from the seat or headrest 12 to enable cleaning, washing, fixing, switching between daytime/night-time transport or other maintenance to the head restraint. The seat fastener 11 is connectable to an upper portion of the seat, for example to the headrest 12 or any other structure positioned behind the head 10 of the sitting person.

In one embodiment the seat fastener 11 is made of flexible material, or the seat fastener 11 may comprise a flexible portion to isolate conduction of vehicle noise or any structural noise from the 5 seat to rest of the head restraint.

The flexible portion may be a strap made of rubber that may be pulled over the headrest 12, where it fastens securely.

The person wears a headband 13. In one embodiment, as in this example, the headband 13 is configured in a cap.

The headband 13 may be a dedicated headband or portion of the cap or a hat.

In one embodiment the headband is part or a beanie.

The cap may be made of disposable or durable material.

The cap may be lightweight or in the shape of a hairnet.

The headband 13 may comprise a restricting portion preventing the headband 13 to fall below ear or nose level.

The restricting portion prevents, in the event of accident or other sudden vehicle movements, the situation where the headband might fall down to neck area and risk injury or choking.

The cap, hat or beanie are examples performing the restricting function.

In one example the restricting portion comprises two straps crossing over the head.

The headband 13 may be made of flexible material.

In one embodiment the headband 13 comprises a hook-and-loop fastener configured to fit the headband 13 comfortable around various head sizes.

The headband 13 is sufficiently wide to be comfortably worn, not causing excessive stress to skin or hair while leaning on it.

The user wears the headband 13 in a seated position.

The user may step up from the seat wearing the headband 13 and return to the o seat to engage the head restraint.

FIG. 1 illustrates the right side of the user S 25 and the head restraint, wherein a right outer strap 14 connects the right side of se the seat fastener 11 to aright side of the headband 13. A left inner strap 15 is + partially shown behind the right outer strap 14 and the seat fastener 11. E FIG. 2 illustrates schematically one exemplary embodiment of the head restraint N as seen from above.

The strap lengths may vary according to the embodiment, io 30 wherein in this example the strap lengths are at least partially exaggerated to > illustrate the functionality.

The seat fastener 11 is on this example configured to be tightened around the headrest 12 by a hook-and-loop fastener 18. The headband 13 is illustrated being separate from the other structure, as it is detachable.

The right outer strap 14 connects the right side of the seat fastener 11 to a right side of the headband 13. The connection point 19 in the right side of the seat fastener 11 is positioned to the right of the centreline.

Having the connection point 19 further right than user's right temple benefits in the head restraint having stable supporting effect.

The left outer strap 17 connects the left side of the seat fastener 11 to a left side of the headband 13, more particularly in this example to a connection point 22. The connection point 20 in the left side of the seat fastener 11 is positioned to the left of the centreline.

Having the connection point 20 further left than user's left temple benefits in the head restraint having stable supporting effect.

In one embodiment, the distance between the connection points 19 and 20 in the seat fastener 11 is greater than the diameter of the headband 13, measured from the user's temples.

In one embodiment, portion of the seat fastener 11 between the connection points 19 and 20 is made of non-flexible material to ensure that the distance between the connection points 19 and 20 is similar when connected to headrests 12 od various sizes.

The head restraint comprises cross-support to improve the pull of the straps on the neck by having two inner straps 15, 16 crossing behind the user's head.

The left inner strap 15 is connected to the same connection point 20 in the seat fastener 11 as the left outer strap 17. The opposite end of the left inner strap 15 is connected to the same connection point 21 at the right side of the headband as the right outer strap 14. The right inner strap 16 is connected to the same o connection point 19 in the seat fastener 11 as the right outer strap 14. The S 25 opposite end of the right inner strap 16 is connected to the same connection se point 22 at the left side of the headband 13 as the left outer strap 17. = The four straps provide four vector-like forces to the user's head 10 when the E: user leans at any direction.

At least two of the four straps 14, 15, 16, 17 tighten N as the user's head 10 leans freely against the head restraint.

The crossing inner io 30 straps 15, 16 provide counter force to the outer straps 14, 15, maintaining a 2 comfortable position for the head 10. Considering a situation, where only the outer straps 14, 15 would hold the head in place, the one support vector per side would cause slight sway to the head 10 when leaning against the head restraint.

The swaying head is usually deemed uncomfortable, possibly inducing travel sickness.

The four straps 14, 15, 16, 17 anchor the head 10 comfortably to various angles, providing adequate freedom of movement to prevent the sensation of numbness in user's neck or upper torso.

Lengths of the straps 14, 15, 16 and 17 may be fitted to any particular seat size to ensure the effect of at least two straps 14, 15, 16 and 17 tightening simultaneously, when the user leans on the head restraint.

The strap width is in one example 2 cm, but various sizes may be used to achieve the same effect.

The left outer strap 17 and the right inner strap 16 are connected to a left headband fastener 23. The left headband fastener 23 is an extension of the left outer strap 17, continuing beyond the connection point 22. The right outer strap 14 and the left inner strap 15 are connected to a right headband fastener 24. The right headband fastener 24 is an extension of the right outer strap 14, continuing beyond the connection point 21. The left headband fastener 23 and the right headband fastener 24 are releasably connected to the headband 13. One example of releasable fastener is a hook-and-loop fastener 25. The releasable fastener 25 allows the user to disengage quickly from the head restraint and engage again when desired.

The hook-and loop fastener 25 defines a portion integrated to the headband 13, wherein said portion may extend from side to side, from ear to ear, via the forehead.

In one embodiment, the user may adjust the positions where the releasable fasteners, such as the hook-and-loop fasteners 25 are attached to the headband 13. The user may o allow some slack to the left headband fastener 23 or the right headband S 25 fastener 24 to enable desired head movement, such as the ability to turn the se head towards a window.

Alternatively, the user may tighten the left headband + fastener 23 and the right headband fastener 24 if he/she prefers fixed position.

E: Alternatively, or in addition, the user may remove the headband 13 or the cap N that is eguipped with the headband 13. The force reguired to disengage the io 30 headband 13 may be calibrated to safety standards, allowing the user to be > disengaged from the head restraint during or after an accident.

The forces required to disengage the headband 13 from the headband fasteners 23, 24 may be calculated to interact safely with airbags or similar safety equipment. In one example, the portion of the hook-and loop fasteners 25 comprises a hook portion of 3 cm long on each side and 2 cm wide strap that restricts the maximum force to disengage the headband 13. In this example the contact area for hook-and-loop is 12 cm?. In the example of FIG. 2, the hook portion is arranged to outer surfaces of the headband fasteners 23, 24. FIG. 3 and FIG. 4 illustrate alternative solution, where the hook portion is arranged to inner surfaces of the headband fasteners 23, 24. Further examples of releasable fasteners between the left headband fastener 23, the right headband fastener 23 and the headband 13 comprise an adhesive, for example a sticky substance that allows the headband fasteners 23, 24 to be disengaged from the headband

13. Another example for attaching releasably to the headband 13 comprises magnets and portions of metal attracting magnets. The head restraint may be adjusted to various head sizes. In one embodiment the left headband fastener 23 and the right headband fastener 24 comprise means for adjusting length. The headband fasteners 23, 24 may comprise interchangeable extensions for users of different sizes. Short or tall people may have head 10 position further from the headrest 13 that medium sized people. In one example the hook-and-loop fastener 25 may comprise extended loop portion at the headband 13, allowing various positions to be connected. One effective position to connect to the headband 13 is around the area of user’s temples. FIG. 3 and FIG. 4 illustrate schematically two alternative ways to construct an o inner crossing strap structure of the head restraint. The inner strap structure S 25 comprises the left inner strap 15 and the right inner strap 16 connected in a se region of space between the headband 13 and the seat fastener 11. = In the example of FIG. 3 the inner structure is illustrated by the connection point E 30, where the inner straps 15, 16 are connected, when the head restraint is fully N assembled. The inner structure consists of a front inner strap 32 connected io 30 between the left headband fastener 23 and the right headband fastener 24 or > between the connection points 22, 21. A rear inner strap 31 is connected between the connection point 20 at the left side of the seat fastener 11 and the connection point 19 at the right side of the seat fastener 11. When assembled, the front inner strap 31 and the rear inner strap 32 are connected in said region of space around the connection point 30 in FIG. 3, between the headband 13 and the seat fastener 11. The left inner strap 15 consists of a left portion of the rear inner strap 31, a right portion of the front inner strap 32 and the connection 30 between the left inner strap 15 and the right inner strap 16. The rear inner strap 31 and the front inner strap 32 may be connected by stitching them together at the connection point 30. In the example of FIG. 4 the inner structure is illustrated by the connection point 30, where the inner straps 15, 16 are connected, when the head restraint is fully assembled.

A left auxiliary strap 41 is connected between the left headband fastener connection point 22 and the left side connection point 20 of the seat fastener 11. A right auxiliary strap 42 is connected between the right headband fastener connection point 21 and the right-side connection point 19 of the seat fastener 11. The left auxiliary strap 41 and the right auxiliary strap 42 are connected in connection point 30 to form the left inner strap 15 and the right inner strap 16. FIG. 5a and FIG. 5b illustrate one example of the straps in the head restraint being tightened and loosened.

Various sequences may be constructed illustrating other head positions or combinations of movements.

In FIG. 5a the user's head 10 leans slightly right and forward.

The headband 13 supports the head 10 as two straps tighten simultaneously, the left outer strap 17 and the left inner strap 15. In this example all other straps stay loose.

Depending on the o position, other combinations of straps may tighten.

As the head 10 leans freely S 25 against the headband 10, the swaying movement stops as at least two straps se tighten simultaneously, of the group defined by the four straps 14, 15, 16 and + 17.
