Description

  The present invention relates to an auxiliary pillow for a headrest attached to a backrest of an automobile seat.

In general, an automobile is equipped with a headrest at the upper end of the backrest in order to prevent occupant cervical spine damage in the event of a collision.
In general, the occupant's front seat is a reclining system, and the backrest angle can be freely adjusted according to the occupant's body shape, driving posture, and preference.
When the angle between the seat and the backrest is nearly 90 degrees, the headrest and head are designed so that there is almost no gap between the headrest and the head to prevent cervical spine damage during a collision. Since the backrest is inclined somewhat rearward, there is a gap between the headrest and the head, and the head is generally not in contact with the headrest.
A conventional technique for protecting the head and preventing cervical spine damage is "auxiliary pillow for automobile seat" according to Japanese Utility Model Laid-Open No. 4-79544. (Patent Document 1)
This is an “auxiliary pillow used for a head rest” according to Japanese Utility Model Laid-Open No. 4-36863. (Patent Document 2)
This is a “mini pillow with rubber band” according to JP-A-8-417. (Patent Document 3)
This is a “car pillow” according to Japanese Patent Application Laid-Open No. 2000-201766. (Patent Document 4)
Etc. are known.
On the other hand, in the general sleep pillow, it is a “pillow” according to the actual application No. 8-1741 whose height can be adjusted. (Patent Document 5)
This is a “height-adjustable herbal pillow” according to Japanese Patent Application No. 6-10186. (Patent Document 6)
This is a “pillow” according to Japanese Utility Model Application No. Hei 1-77241 whose height can be adjusted. (Patent Document 7) and the like are known.
In general, a waist cushion for correcting lumbar vertebrae and a mini pillow for resting in a vehicle are known as conventional techniques.

Japanese Utility Model Publication No. 4-79544 Japanese Utility Model Publication No. 4-36863 JP-A-8-417 JP 2000-201766 A Japanese Utility Model Application No. 8-1741 Japanese Patent Application No. 6-10186 Japanese Utility Model Application No. 1-77241

However, the prior art has the following problems.
Even when the angle of the backrest is changed by the occupant, it is important to maintain a state in which there is almost no gap between the existing headrest and the occupant's head in order to prevent cervical spine damage at the time of collision.
The angle of the backrest varies depending on the occupant's body shape, driving posture, and preferences, and the size of the gap between the headrest and the head varies accordingly.
In the past, it was impossible to instantaneously satisfy the gap between the head and the headrest caused by the difference in the angle of the backrest in an extremely short time from getting on to starting.
As a prior art, “Auxiliary Pillow for Automobile Seat” (Patent Document 1) according to Japanese Utility Model Laid-Open No. 4-79544, which is intended to protect the head, and “Head Rest Into” according to Japanese Utility Model Laid-Open No. 4-36863. “Auxiliary pillow” (Patent Document 2) and the like are special pillows having a specific shape, and “Mini Pillow with Rubber Band” (Patent Document 3) according to JP-A-8-417 and JP-A 2000-201776. "Car pillow" (Patent Document 4), etc. related to No. is known, but since the shape of the pillow body is constant, it is not possible to adjust and satisfy instantaneously according to various gaps by the occupant There is a problem that it cannot be done.

On the other hand, although not in the same category, in a general sleep pillow, “pillow” according to Japanese Patent Application No. 8-1741 for adjusting the height of the pillow body (Patent Document 5) and “Japanese Patent Application No. 6-10186” A herbal pillow whose height can be adjusted "(Patent Document 6), a" pillow "(Patent Document 7) according to Japanese Utility Model Application No. 1-77241 in which the height can be adjusted are known.
However, even if they are attached to the headrest, they are only attached to the desired height in the extremely short time from boarding to the start without changing the horizontal attachment center position while attached to the headrest. However, there is a problem that it is not possible to instantaneously satisfy various gaps by adjusting freely.

(B) Long-time driving is a factor that causes a burden on the lower back and causes back pain along with increased fatigue.
In general, the driving posture is such that the lumbar vertebra is curved backward, but in order to reduce fatigue and prevent back pain, it is important to maintain the posture in which the lumbar vertebra, which is a normal posture of the human body, is curved forward.
In general, a waist cushion is known, but since the shape is constant, there is a problem that it cannot be applied to all people with different body shapes, driving postures, and preferences.

(C) When resting with a large backrest in the vehicle, there is an unevenness in the connecting portion between the headrest and the backrest, and the upper part of the back of the head hits the headrest, causing an unnecessary burden on the cervical vertebra and causing a problem of being unable to rest.
“Mini pillow with rubber band” according to Japanese Patent Laid-Open No. 8-417 and “Car pillow” according to Japanese Patent Laid-Open No. 2000-201766 are suitable for everyone with different shapes and preferences because the shape is constant. There is a problem that it cannot be done.
In order to solve the above problems, the present invention provides an auxiliary pillow that is slightly small and versatile.

In order to solve the above-described problems, the present invention forms a cloth-made cylindrical bag body and appropriately fills the inside of the cylindrical bag body with a filler.
A through hole is provided in the center of both end faces of the cylindrical bag.
A strap is inserted into the through hole so as to move, and sliders that can move along the strap are provided on the outer sides of both ends of the cylindrical bag.
Both end surfaces of the cylindrical bag body are movable along the strap along with the movement of the slider.
A connector is provided at both ends of the strap.
The slider inserts a push button member into the center hole of the main body member, and pierces both the insertion holes through which the straps run.
The push button member is locked to the strap by shifting the insertion hole from each other so as to protrude from the center hole by a spring pressure.
The slider can be moved along the strap by pressing the slider's push button member with fingers and aligning the respective insertion holes. When the finger is released, the insertion hole is displaced by the spring pressure and locked to the strap. .
An auxiliary pillow for an automobile headrest having the above configuration.

(A) The auxiliary pillow of the present invention is appropriately attached to the center position of the headrest, and both sliders are moved toward the center or in the opposite direction, so that the position of the auxiliary pillow body does not change and the length of the pillow body is not changed. By adjusting the height, the height can be adjusted instantly and freely.
The height of the pillow body is adjusted by instantaneously adjusting only the length of this auxiliary pillow to the various gaps between the headrest and head, which have been impossible in the past, depending on the occupant's body shape, driving posture, and preference. It can be adjusted to a desired height and satisfied to prevent cervical spine damage.

(B) Since the height of the pillow body is adjusted by the movement of both sliders, there is an advantage that the movement distance of each slider is halved and the effect is doubled by a short distance movement.
Further, if the movement distances of both sliders are different, correction of the attachment center position of the pillow body and movement to the left and right are also possible.

(C) With this auxiliary pillow alone, according to the occupant's body shape, driving posture and preference, both sliders can be adjusted to the desired pillow body height by moving both sliders toward the center of the pillow body or in the opposite direction. Thus, by pressing and holding at a desired position between the lumbar region and the backrest, the lumbar vertebra can be bent forward to correct the lumbar vertebra, thereby reducing fatigue during driving and preventing back pain.

(D) When resting with the backrest greatly lowered, as described above, both sliders of this auxiliary pillow are adjusted to the height of the desired pillow body instantly by moving both sliders toward the center of the pillow body or in the opposite direction. By temporarily installing the connecting portion between the backrest and the headrest, the unevenness of the connecting portion can be eliminated, and it can be used as a pillow, and a repose can be obtained.
In addition, the height adjustment of the pillow body can be freely and instantly performed in the same manners (i), (b), (c), and (d).

(E) Furthermore, the simultaneous use of Example 1 and Example 2 has the effect of preventing cervical spine damage and simultaneously reducing fatigue and preventing low back pain by correcting the lumbar spine to a normal posture. In addition, the combined use of Example 2 and Example 3 has a synergistic effect such as reducing fatigue and preventing back pain by correcting the lumbar vertebrae and simultaneously obtaining rest at the time of rest in the vehicle, and is highly versatile. is there.
The present invention has the above effects.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, a cloth-made cylindrical bag (1) is formed and filled with a filler (2) as appropriate.
(B) The through holes (4a) and (4b) are provided in the center portions of both end faces (3a) and (3b) of the cylindrical bag body (1), respectively.
(C) A string (5) longer than the cylindrical bag is inserted into the through holes (4a) and (4b) so as to move, and a slider (6a) movable along the string (5) ( 6b) is provided on the outer side of both end faces (3a) and (3b) of the cylindrical bag.
(D) Both end faces (3a) and (3b) of the cylindrical bag body move along the strap (5) with the movement of the sliders (6a) and (6b).
(E) Connecters (7a) and (7b) are provided at both ends of the strap (5).
(F) As shown in FIG. 2, the slider inserts the push button member (21) into the central hole of the body member (22), and the insertion hole (23), insertion hole ( 24) are drilled together.
(G) The slider is locked to the strap (5) by causing the push button member (21) to protrude from the main body member (22) by the spring (25) pressure and shifting the insertion holes (23), (24) relative to each other. To do.
The present invention has the above structure.

An auxiliary pillow according to Example 1 of the present invention will be described.
As shown in FIG. 3, the auxiliary pillow (10) is detachably attached to the center position (▽ mark) of the existing headrest (11) by means of a band (13) or the like through the couplers (7a) and (7b). Install.
When both hands move toward the center while pressing the push button members (21) of the sliders (6a) and (6b) with fingers, the position of the attachment center portion of the cylindrical bag (1) (FIG. 3, In FIG. 4 (), the length of the cylindrical bag (1) is shortened and the height is increased without fluctuation.
When the finger is released from the push button member (21) of the sliders (6a) and (6b) at a desired position, the length of the cylindrical bag body is set by being locked to the strap by the spring (25) pressure. The height is set.
Similarly, when moving in the opposite direction, the length of the cylindrical bag body (1) becomes longer and the height becomes lower.
Since both end faces (3a) and (3b) of the cylindrical bag body move along the strap (5) together with the slider, there is no change in the overall length of the strap (5) inserted through the cylindrical bag body, and the cylindrical bag Since there is no change in the center position of the bag body, it is not necessary to adjust the position in the horizontal direction. As a result, it is not necessary to remove the auxiliary pillow (10) attached to the headrest and adjust the height of the pillow body, and there is no need to adjust the position in the horizontal direction and reattach it. Only by adjusting the length of the pillow body, the height of the pillow body is instantaneously adjusted according to the size of the gap.
As described above, the auxiliary pillow moves the cylindrical bag body end faces (3a) and (3b) toward the center of the pillow body in the fixed position attached to the headrest (11) or in the opposite direction together with the slider. Thus, the center position of the attached pillow body does not change, and the height of the pillow body can be adjusted instantaneously.
Moreover, since the movement of the slider is optional, it can be performed in a stepless manner from a minute adjustment to a large adjustment, and it is easy to operate and can be instantly adjusted to quickly respond to various gaps.
In addition, since the height of the auxiliary pillow is adjusted by the movement of both sliders, there is an advantage that the movement distance of each slider is halved and the effect is doubled by movement of a short distance.

By the way, when the center position of the auxiliary pillow body is shifted, the height adjustment of the pillow body can be corrected to the center position by moving the left and right sliders as appropriate. When attached to the center position, if the moving distance of both sliders is greatly different, the attachment center position of the pillow body changes. Therefore, it is usually desirable to move both sliders in the same direction toward the center or in the opposite direction.
The method of attaching the auxiliary pillow to the headrest (11) is not particularly limited as long as it is a method that allows easy attachment and detachment of magnets, hook-and-loop fasteners, and the like, and does not change the attachment center position of the pillow body.
