[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0016]
[Example 1]
FIG. 1 is a perspective view of an automobile seat cushion 100 according to the first embodiment. FIG. 2 is a cross-sectional view taken along the line AA in FIG. FIG. 3 is a perspective view illustrating a usage state of the company seat cushion 100 according to the first embodiment.
[0017]
The automobile seat cushion 100 according to the first embodiment includes a bag body 30 made of a sealing sheet that forms an outer shell, and a stretchable cushion mat 40. The material of the sealing sheet is not particularly limited as long as air does not leak from the sheet to the outside. In Example 1, a vinyl chloride sheet is used. The bag body 30 is provided so that a space is formed in each of the seat portion 10 and the backrest portion 20. Although the shape of the seat part 10 and the backrest part 20 is not specifically limited, It is desirable to form in the shape suitable for the seat of the motor vehicle. Further, the height of the backrest portion 20 is not limited, and may be formed low so as to hold only the vicinity of the waist as shown in FIG. 3, or the entire backrest of the automobile seat as shown in FIG. You may form high so that it can cover.
[0018]
The inner space of the bag 30 is for inserting a stretchable cushion mat 40 and a certain amount of air, which will be described later. Although the size of the internal space is not particularly limited, since the cushion cushion 40 of the stretchable cushion mat 40 and the fixed amount of air inserted serves as a cushion for the seat portion 10 and the backrest portion 20 respectively, a human can sit down. In such a case, it is desirable to have a size that can hold the buttocks, waist, and back. And between the seat part 10 and the backrest part 20, the air inflow port 33 is provided so that air can mutually flow in / out each internal space.
[0019]
The stretchable cushion mat 40 is disposed in the internal space of the seat 10 and the backrest 20 of the bag 30. The shape, thickness and size of the elastic buffer mat 40 are not particularly limited. Moreover, the magnitude | size and thickness of the mat | matte arrange | positioned by the seat part 10 and the backrest part 20 may differ. In Example 1, a urethane mat having a thickness of about 5 cm for the seat portion 10 and a thickness of about 2 cm for the backrest portion 20 is used. Then, a certain amount of air is inserted simultaneously with the stretchable cushion mat 40 and completely sealed so that air does not leak outside. The amount of air inserted is a pressure that allows air to freely flow in and out between the seat portion 10 and the backrest portion 20 depending on the human weight, and can be adjusted by the inflow amount of air depending on the respective sinking conditions. Inserted. If air is inserted at an excessively high pressure, the body is held only by the air pressure, and the elastic buffer mat 40 is held without being crushed depending on the weight, and the buffering effect of the internal elastic buffer mat 40 is also provided. It can no longer be obtained. In addition, almost no air flows in and out as much as the weight is applied, and the amount of subsidence due to changes in the pressure of the seat portion 10 and the backrest portion 20 cannot be adjusted. As a guideline, it is better to insert the air at a pressure below the extent that the automobile seat cushion 100 can be easily folded in half, or that it can be easily folded in the line AA in FIG. .
[0020]
The automobile seat cushion 100 manufactured in this way is used by being laid on the automobile seat as shown in FIGS. When a person sits on the cushion 100 for an automobile seat laid in this way, the elastic cushion mat 40 of the seat portion 10 sinks due to the body weight, and the air present there passes through the air inlet 33 as indicated by the arrows in FIGS. As such, it flows into the backrest 20 and swells. Since the sinking seat 10 sinks in conformity with the shape of the buttock, a stable seating can be secured, and the seating 10 can be kept constant without being completely crushed by the air pressure and the repulsive force of the elastic cushion mat 40. Therefore, it is possible to effectively buffer the vibration from the automobile. On the other hand, when the backrest portion 20 is formed low only on the waist portion as shown in FIG. 3, the backrest portion 20 bulges so as to fill the space between the seat and the waist and can stably hold the position of the waist. Moreover, since it is hold | maintained by the air and the elastic buffer mat | matte 40, the vibration which concerns on a waist can be buffered. Moreover, when it forms so that it can lean the whole back like FIG. 4, the cushion of the backrest part 20 will dent moderately with the pressure by a back. Since the dent is adapted to match the shape of the back, it is possible to ensure the positional stability of the back and to have a certain buffering effect. Furthermore, when the body is moved during driving, the seat portion 10 and the backrest portion 20 are interlocked to adjust the bulge according to the pressure caused by the movement, so that a stable seating state can be achieved at any position. Can be secured. For example, even when the upper body tilts slightly forward due to sudden braking, the pressure of the seat 10 increases, and a large amount of air flows into the backrest 20 to ensure followability to the tilted body. When seating is ensured and the body returns to the original position, the pressure on the back is increased and air flows into the seat portion 10 to return to the initial state and secure stable seating.
[0021]
[Example 2]
FIG. 5 shows an automobile seat cushion 100 according to the second embodiment. FIG. 6 shows a cross-sectional view taken along the line BB of FIG. 7 and 8 show the usage state of the automotive cushion 100 according to the second embodiment. The automobile seat cushion 100 according to the second embodiment is the same as the first embodiment in that it includes a bag body 30 made of a hermetic sheet that forms an outer shell and a stretchable cushion mat 40. However, four bag bodies 30 are formed, the right seat portion 11, the left seat portion 12, the right backrest portion 21, and the left backrest portion 22, and an internal space is formed in each. Furthermore, the space between the right seat portion 11 and the left seat portion 12 and the space between the right backrest portion 21 and the left backrest portion 22 are completely sealed so that air cannot flow in and out of each other. Further, no space is formed in the vicinity of the center of the front end α of the right seat portion 11 and the left seat portion 12, that is, the portion where the leg portion is placed when a person sits on the automobile seat cushion 100.
[0022]
Four elastic cushion mats 40 are inserted into the inner space of the bag body 30 and conform to the shape of the inner space of the right seat portion 11, the left seat portion 12, the right backrest portion 21, and the left backrest portion 22, respectively. . An air inflow port 33 is provided between the right seat 11 and the right backrest 21 and between the left seat 12 and the left backrest 22 so that air can flow in and out of the respective spaces. .
[0023]
Further, the automobile seat cushion 100 according to the second embodiment is provided with an air adjustment valve 50 so that the amount of internal air can be adjusted. The form and function of the air adjustment valve 50 are not particularly limited. Thereby, the amount of air can be adjusted according to a body weight, a height, and the size of a body, and it can be set as the effective cushion 100 for automatic passenger seats.
[0024]
An appropriate amount of air is inserted from the air adjustment valve 50, and the air adjustment valve 50 is sealed so that air does not leak outside. The amount of air to be inserted is inserted at such a pressure that air can freely flow in and out of the seat portion 10 and the backrest portion 20 depending on the human body weight, and each sinking can be adjusted by the amount of air flowing in. This is the same as in the first embodiment.
[0025]
The automobile seat cushion 100 manufactured in this way is used by being laid on the automobile seat as shown in FIGS. When a person sits on the laid automobile seat cushion 100, the elastic cushion mat 40 of the seat portion 10 sinks due to the weight, and the air present there passes through the air inlet 33 and the right seat portion 11 and the right backrest portion 21 respectively. In between and between the left seat portion 12 and the left back portion 22, air flows in and out as indicated by arrows. The basic air inflow and outflow action and the action of the stretchable cushion mat 40 are the same as those in the first embodiment. However, in this second embodiment, the left and right internal spaces are formed independently, so that the air It does not move left and right beyond the center. Therefore, for example, even when the body is moved to the left or right, a large amount of air moves to either the left or right to ensure a stable seating without sinking or shrinking more than a certain amount on one side. be able to. For example, if there is no air blocking part in the center, and the body is tilted to one side due to a curve or the like during driving, if a large amount of air moves, it is used together with the elastic cushion mat 40, so only air Although it has a considerable stability compared to the above, there is a possibility that the air that is biased to one side causes a large inclination on the left and right of the seat portion 10 to make the seating state unstable and also difficult to return to the normal seating state There is. However, by forming the left and right sides independently as in the second embodiment, the inflow and outflow of the left and right air can be prevented, and an extreme inclination can be prevented from being formed in the seat portion 10. is there. In addition, although the seat part 10 was demonstrated, this is the same also in the backrest part 20. FIG.
[0026]
Furthermore, in the second embodiment, since no space is formed at the left and right front ends α of the seat portion 10, the leg portions can be positioned in a more natural state. That is, since the pressure applied to the seat 10 is smaller than that of the buttocks, the legs may be formed in a state where the legs are lifted, but the place where the legs are arranged should not be expanded. As a result, the leg portion is also placed at the position where it sinks in the same manner as the buttocks.
[0027]
Further, FIG. 9 shows a modification of the second embodiment. In this modification, a non-space region in which no space is formed and the buffer mat 40 is not formed is formed in the backrest portion 20. This non-space region is formed wider in the center toward the upper portion of the backrest portion 20, so that a bulge state suitable for the shape of the back can be secured. This is because the back of the back has a relatively round back, but the back becomes wider and flatter toward the shoulder. Therefore, the body can be reliably held from both sides according to the back part such as the waist and shoulder parts, and a stable posture can be maintained.
[0028]
Further, FIG. 10 shows another modification. In FIG. 10, the space of the seat portion 10 is divided and formed with a partition inside, and the stretchable cushion mat 40 to be inserted into the internal space is divided and formed. However, since the present invention is characterized by the movement of air, it is necessary to form this threshold so that the air can move back and forth. Thus, by providing a partition in the middle, it becomes possible to prevent the elastic cushion mat 40 in the middle from moving toward the end.
[0029]
[Example 3]
FIG. 11 shows an automotive seat cover according to the third embodiment. In this example, the automobile seat cushion 100 is inserted into the automobile seat cover 110 and used. The shape, material, function, etc. of the automobile seat cover 110 itself are not particularly limited. A more comfortable cover for an automobile seat can be obtained by using a more comfortable cloth or leather cover on the surface that directly touches the body. In addition, since the cover is structured to be easily attached to the seat of the automobile, the automobile cushion 100 can be easily attached to the automobile seat, and the position is also stabilized, so that the body can be held more stably. .
[0030]
