DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary pillow device for a vehicle seat which can be attached to a vehicle seat or the like so that a occupant can take a nap.

[0002]

2. Description of the Related Art In most cases, a driver takes a nap while sitting in a vehicle seat at the time of rest or the like when driving a car.
In such a case, during sleep, the head supported by the headrest of the seat or the like often slips and wakes up as a snap. Therefore, a proposal has been made to attach a pillow-shaped object capable of holding the head to the vehicle seat so that the head does not swing. For example, the "safety sleep pillow for seat" disclosed in Japanese Utility Model Registration No. 3015699 has a structure in which the air sac 1 is straddled on the upper edge of the backrest of the seat, and the retaining ring 21 is hooked and fixed by the hook 13 of the side band 12. And the both cheeks of the human body are held tightly by the side holding parts 2, and the adjustment band 3
Is tightened in front of the face so that you can sleep while holding your head. Further, an "auxiliary pillow for an automobile seat" disclosed in Japanese Utility Model Laid-Open Publication No. 4-79544 is mounted on a headrest 4 of the seat 1 by tightening with a hook-and-loop fastener or the like so as to be wound around a mounting portion 9 of the auxiliary pillow 5. The head of the occupant is held by a pair of pad portions 6 located on the left and right sides of the head of the occupant.

[0003]

However, in the above-mentioned "safety sleep pillow for a seat", as can be seen from FIG. 2, the adjustment band 3 is tightened at the front of the face and only the both cheeks are held by the side holding portion 2. The entire head is held so as to be clamped, and the head is almost completely fixed and cannot be moved, so the degree of freedom in moving the head is extremely low. In fact, during sleep, the upper body, especially the head, is tilted occasionally to adjust the posture unconsciously, while maintaining the posture during sleep. Therefore, if the degree of freedom of the head during sleep is extremely low, it is not possible to adjust the sleeping posture, and there is also a pressure feeling that the head is sandwiched between the side holding portions 2, making it difficult to sleep and unable to sleep soundly. Further, the "auxiliary pillow for the automobile seat" is such that a pair of pads 6 located on the left and right sides of the head of the occupant fix the occupant's back part in a fixed place in an embedded manner, and Only the head can be moved and the degree of freedom of the head is low. In addition, auxiliary pillows of the type that can be placed from above must be bulky and integrally molded to reinforce the supporting part of the head, which not only increases the manufacturing cost but also increases the degree of freedom of the head. There is a problem that it becomes low and you cannot sleep soundly.

The present invention has been made in view of the above-mentioned conventional problems, and one object of the present invention is to adjust and hold a seated person's head in an arbitrary tilted state and to improve the degree of freedom of the head. It is an object of the present invention to provide an auxiliary pillow device for a vehicle seat that can sleep deeply and adjust to a sleep while adjusting a sleeping posture. Another object of the present invention is to provide an auxiliary pillow device for a vehicle seat which can be easily attached to and detached from a vehicle seat by a simple device configuration, and which can be mass-produced and can keep the manufacturing cost of the device low.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a backrest of a vehicle seat S having a locking hole 16 which is inserted into a support rod 106 for mounting and adjusting the height of a headrest 105. 100 upper part 102 and the headrest 1
05, and the mounting portion 12
And a head receiving portion 14 for receiving the head H of the occupant M. The auxiliary pillow device 10 is provided for a vehicle seat.

The locking holes 16 are provided in a row, and the mounting portion 12 is moved in a direction perpendicular to the running direction of the vehicle while changing the locking holes 16 inserted into the height adjusting and mounting support rod 106. The seat S may be provided on one side of the occupant M so as to be displaced in a misaligned manner.

Further, the head receiving portion 14 may be connected to the mounting portion 12 so that the mounting angle can be set and held three-dimensionally.

The mounting portion 12 may be a flat base.

The support rod 106 for height adjustment and attachment is
The locking holes 16 may be composed of at least two or more locking holes 22 and one or a plurality of long holes 24 arranged in series with the locking holes 22.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle seat auxiliary pillow device according to the present invention can maintain a high degree of freedom of a head during a nap while sitting in a vehicle seat. This is an auxiliary pillow device that allows a comfortable sleep while being adjusted and held at the position.

[0011] The auxiliary pillow device for a vehicle seat is provided with a mounting portion attached to an upper portion of a backrest or a headrest portion of the vehicle seat, and is provided so as to extend from the mounting portion. And a head receiving portion that can be tilted and held while being displaced to one side. The auxiliary pillow device for a vehicle seat may be attached to an upper part of a backrest or a headrest portion of the vehicle seat via a mounting portion, regardless of the mounting method and configuration as long as it can be easily attached to and detached from the vehicle seat. May be arbitrarily selected in accordance with the shape of.

The head receiving portion is provided to extend from the mounting portion, and it is important that the head of the occupant can be tilted and held on the head receiving portion by shifting the head of the occupant from the steady position to one side. It is. For example, the head is tilted to one side in the traveling direction to the right or to the left, that is, it is leaned while shifting it from the neck in a displaced manner and deposited in the head receiving part and supported, so the degree of freedom to move the head is extremely high You can take a nap while adjusting your sleeping posture. The configuration of the head receiving portion is arbitrary, including the size, shape, and extension method, as long as the head receiving portion can be tilted and held by shifting the head to one side in a misaligned manner.

[0013] The mounting portion may be provided so as to be sandwiched between the upper portion of the backrest and the headrest portion.
This mounting portion can be mounted on a seat of a type in which a headrest portion can be attached to and detached from an upper portion of a backrest, and can be mounted by a simple operation of simply being sandwiched between the upper portion of the backrest and the headrest portion. In addition, when it is attached to another vehicle seat or when it is unnecessary, it can be easily removed by opening the clamp of the attachment portion. The size and configuration and the configuration thereof are arbitrary as long as the mounting portion is easily sandwiched between the upper portion of the backrest and the headrest portion. Since the supporting force of the mounting portion is assisted by the pinching force, the mounting portion main body can be reduced in size and weight, so that its production can be easily mass-produced. The material is preferably formed of stainless steel, which has high strength, is hardly rusted, and has good workability. However, it may be formed of a metal such as rigid steel, a light alloy, a hard synthetic resin, or the like.

The mounting portion has a locking hole which is inserted into a support rod for adjusting the height of the headrest and supports the mounting portion so as to be sandwiched between the upper portion of the backrest and the headrest. . By inserting the support rod for height adjustment mounting of the headrest into the locking hole of the mounting part, the mounting part is securely fixed by being sandwiched between the upper part of the backrest and the headrest so as not to fall off. In other words, since the support rod is inserted into the locking hole by penetrating the mounting portion in a skewered manner, the mounting portion sandwiched and supported between the upper part of the backrest and the headrest does not easily fall off the support rod.

A plurality of locking holes may be provided at arbitrary intervals. This locking hole is formed only by drilling a hole having a diameter slightly larger than the mounting portion, through which the support rod of the headrest can be inserted, so that the mounting portion can be mass-produced and the manufacturing cost can be reduced. It is preferable to provide a plurality of arrangements so as to match the interval width of the support rods of the headrest, and the position of the locking holes through which the support rods are inserted can be selected to shift the mounting portion. As a result, it is possible to change the set position and direction of the head receiving portion extending from the mounting portion.

The head receiving portion may be connected to the mounting portion so that the mounting angle can be set and held three-dimensionally. The head receiving portion may be connected to the mounting portion so that the mounting angle can be freely set. For example, a head receiving portion that can be easily adjusted by holding the head receiving portion with a hand is preferable. For example, a configuration that can freely adjust and hold the angle in three dimensions including not only a fixed direction such as a vertical direction and a horizontal direction but also an oblique direction is more preferable.

[0017] The head receiving portion may be formed of a pillow bar. The head receiving part is connected so as to extend from the mounting part, and the head is tilted to one side and approached, and the head shape is used to stably hold the side of the head and turn over and adjust the sleeping posture It is preferable to form the pillow into a pillow-shaped rod having a length that does not easily fall off even if the part is moved back and forth. For example, a rigid rod or the like capable of holding the head may be coated with a soft and elastic material as a core to an arbitrary thickness. In this case, the shape and shape of the rod having a circular cross section are simple, the formation is easy, the productivity is high, and the manufacturing cost is low. However, the present invention is not limited to this, and may be an oval cross section or the like, and its dimensions, shape, and material are arbitrary.

[0018] The mounting portion may be a flat base. In the case of a flat base body, it is mounted in close contact with the gap between the upper part of the backrest and the headrest. For example, in the case of a rigid metal material, the base body is formed to be thin, and the mounting portion can be fixed by being reliably pressed by the headrest, and the head receiving portion connected to the mounting portion is preferable without shaking. Further, if the flat base body is formed of, for example, stainless steel or steel plate, the processing is simple, mass production is possible, and the manufacturing cost can be reduced. In addition, it may be formed from a light alloy having high rigidity or a hard synthetic resin.

The base body is provided with the locking hole, and two support rods are inserted through the locking hole. The locking hole is provided with at least two or more locking holes, and And one or a plurality of long holes arranged in a circle. Two mounting rods are inserted into the locking holes and the long holes provided in the base body, and the mounting portion is supported and mounted,
The vehicle seat allows the support rod to be inserted through the support rod regardless of whether the interval between the support rods of the headrest is wide or narrow. That is,
If there is a margin for the adjustment width by the length of the long hole in the longitudinal direction, and if there is a type of interval between the support rods of the headrest, if it is within the adjustment width, insert the two support rods at an interval. As a result, the support rod can be reliably supported so as not to rotate about the support rod.

The head receiving portion may be formed in a concave shape along the shape of the head to be held. When the head is tilted to the head receiving portion, the head is received as if it falls into a concave portion curved along the shape of the head, is securely supported, and the head can nap while being stably held without swaying. The shape of the concave portion may be arbitrarily formed in the head receiving portion, for example, as long as the head rolls and does not easily pop out.
