Abstract
An inflatable, contoured lying and seating area has a cloth and/or an upholstery cover. An inflatable outer chamber incorporated in the cover defines the contours of the lying and seating area. The outer sleeve defining the inflatable outer chamber is attached to an inner sleeve defining an inner chamber. As the outer chamber is inflated, the shape of the outer chamber defines the vertical height of the inner chamber which defines the boundaries of the outer chamber. Depending on the vertical height of the inner chamber, the contours of the seating and lying area can be optimized to provide persons occupying area optimal orthopaedic support.

SITTING AND COVER
Background of the Invention 1. Field of the Invention The present invention relates in general to inflatable, contoured mattresses suitable for lying on or sitting on, combined with a supporting surface and/or a cover. Provision is made that this type of contoured mattress be used as a head cushion, as a neck support, as a combination with an existing mattress or as a loose cover for a pillow. Alternatively, the invention can also find application as a seating area in conjunction with work and recreational chairs, as well as car seats or the like. Stuffed furniture may be equipped with mattresses according to this invention.
2. Description of the Related Art Mattresses inflated by air are well known in the prior art. A simple air mattress is an example of such a construction. Such an air mattress is typically contoured in a rectangular boxlike form and, when viewed from the side, a right angle profile is apparent. The lying area is consequently a straight and even surface throughout the mattresses' breadth and length - and is typically devoid of contours.
This type of air mattress is unsuitable for use in a bed or in a stuffed chair because it allows no air flow. Such mattresses therefore tend to be uncomfort-able to lie on. Further, such mattresses do not adapt to conform to the human shape.
Some prior air mattresses are contoured. The contouring of the lying area, when not weighed down, has a certain shape or lying profile. This lying profile is designed to provide optimal orthopaedic support for the body's surfaces and to prevent any point contact with same. The disadvantage of these contoured air mattresses is the fact that they are straight and boxlike in shape which leads to unacceptable body positioning, for instance, by concentrating the weight at one point of the lateral part of the head.
This concentration occurs whenever the sleeper moves, for example, from his or her back to his or her side.
The prior art discloses air mattresses covered by a suitable upholstery material and/or, at the very least, equipped with an outer cover. The prior art also reveals air mattresses covered with pure synthetic material as well as others covered by layered textile materials.
At the present state of the art in air mattresses there is a significant disadvantage: the air mattresses lack a damping element which would contribute to the comfort quotient of the article. In such mattresses forces applied to one side of the mattress can be transmitted to the occupied area. There is no provision for any damping element which could prevent such force transfer (for example by preventing a force applied to the bottom portion or the duckboards of the mattress from affecting the occupied area).
What is needed is an air mattress for lying on or for sitting on, which provides more comfort than is available in prior art air mattresses. In particular, there is a need for air mattresses of the type which use upholstery material and/or a covering of the type described above and provide a pre-contouring conformation or adaptation to the portions of the body resting thereon as well as providing a damping element to minimize the discomfort caused by force applied to the mattress.
SUMMARY OF THE INVENTION
The premise for this invention is that the air mattress is covered by a suitable upholstery material and/or is equipped with an outer cover allowing it to be utilized as a mattress, or as a pillow for the head or the seat. According to the invention, the resting area is to be made up out of a synthetic material that allows air to pass through freely, or optionally out of a textile material with the same property, which may be covered by a synthetic material which also provides free air penetration.
One technical advantage of the invention derives from the fact that the mattress comprises two chambers: an outer chamber which provides the shape for the contoured occupied area and an inner chamber that serves as support for the outer chamber by maintaining the separation of the inner and outer chambers. The height of the inner chamber defines and controls the resting profile of the outer chamber, while simultaneously, the inner chamber forms a damping element.
This inner damping element provides yet another advantage: according to the specifications of the invention, it permits the outer occupied area to form a contoured surface. Such contouring or, formation structuring, has as its primary aim the use of the invention as a head pillow since it thereby provides an excellent support for the neck. Thus such a head pillow with a contoured lying surface is of optimal advantage when sleeping on one's back or on one's side.
Another example of the advantage of the device is when used in its entire surface as a bed since it's resting area can be optimized to accommodate bodily contours. Thus the contouring can provide optimal adaptation to the spinal column for a person in a prone position.
Another important feature of the invention is the fact that it calls for an occupied surface supported by an outer chamber combined with an inner chamber designed to optimize the effect of the outer chamber.
In a preferred embodiment of the air mattress the outer chamber is inflatable, and could be inflated with a gaseous or liquid medium. In this embodi-ment the inner chamber is separated from the outer chamber in an airtight form. This provides a pillow function between the outer chamber and the airtight inner chamber which is separated from and enclosed by the outer chamber. In this first embodi-ment, the inner chamber can be treated on its own by having its own method of inflation: thus both chambers can be equipped with their own separate means of inflation.
In another alternative embodiment provision can be can be made such that the inner chamber is not separately inflatable but instead is provided with a constant volume of inflation.
In yet another alternative embodiment no provision is made for the inner chamber to have an inflation device: its air supply comes solely from the outer atmosphere through a tube not connected to the occupied surface. This third embodiment provides an important advantage: the total air transmission through the inner chamber, which is separated from the outer chamber, comes about by having suitable bore holes incorporated on the upper and lower surfaces of the inner chamber. Thus varying weight distribution on the occupied surface acts in a constructive way so that the configuration of the occupied area will change its form depending on the weight distribution. When a weight change occurs on the occupied area air is drawn into the inner chamber by the lower bore holes and when another weight change occurs, air is expelled through the same bore holes. Since the bore holes are also incorporated into the outer chamber in an airtight manner this causes a vertical aeration of the occupied area.
The aeration of the inner chamber occurs separately from that of the outer chamber which maintains a specified constant volume of air. When the occupied surface is used as a neck or other support, an excellent aeration effect occurs because when a weight change occurs, air is drawn in from below and is forced through the inner chamber to the occupied surface.
A further aeration effect occurs when the entire occupied area is covered with a textile material. The textile material provides a certain resistance to the air and therefore optimizes the effect by creating yet another air chamber which distributes the air throughout the area covered by the textile material before it can be expelled to the outside. In yet another alternative embodiment an additional health giving effect can be derived from using substances that can be placed between the mattress and the textile covering, for instance, herbs, cotton, wool or fragrances in ether form.
A primary advantage of the invention is in the presence of an inner chamber which is connected to the outer chamber providing an intervening space allowing for varying forms of contouring. The degree of contouring depends on the dimensions of the chambers, particularly the vertical height of the inner chamber and on the points of contact between the outer and inner chambers. If the outer chamber is filled with a certain volume of air, the inner chamber is extended and adapts to the contours of the outer chamber due to the upper and lower connections between the two chambers. In this manner the inner chamber becomes a supporting and damping element which supports the contouring of the outer chamber. In this manner it becomes possible, for example, to use the device as a neck support, in particular as a middle concave neck support which continues on either side into convex forms.
Various club shaped forms can be achieved by the differential aeration of the device.
The same bodily adaptation can be obtained when the mattress is used for lying down, depending on the formation of the inner chamber. In this embodi-ment the spinal column and body can be ideally supported since pressure on the outer chamber results in appropriate pressure changes in the inner chamber, thereby bringing the required support to the spinal column. On the one hand the mattress provides optimal bodily adaptation through contouring when not weighted down and on the other hand, it provides a further adaptation to the body shape since the outer chamber and/or the inner chamber is filled with a gaseous or liquid medium which provides - when weighted down - a proper weight distribution for the bodily parts.
The aeration system also comes into play here, a system which is separate and independent of the contouring system.
This type of air mattress is unsuitable for use in a bed or in a stuffed chair because it allows no air flow. Such mattresses therefore tend to be uncomfort-able to lie on. Further, such mattresses do not adapt to conform to the human shape.
Some prior air mattresses are contoured. The contouring of the lying area, when not weighed down, has a certain shape or lying profile. This lying profile is designed to provide optimal orthopaedic support for the body's surfaces and to prevent any point contact with same. The disadvantage of these contoured air mattresses is the fact that they are straight and boxlike in shape which leads to unacceptable body positioning, for instance, by concentrating the weight at one point of the lateral part of the head.
This concentration occurs whenever the sleeper moves, for example, from his or her back to his or her side.
The prior art discloses air mattresses covered by a suitable upholstery material and/or, at the very least, equipped with an outer cover. The prior art also reveals air mattresses covered with pure synthetic material as well as others covered by layered textile materials.
At the present state of the art in air mattresses there is a significant disadvantage: the air mattresses lack a damping element which would contribute to the comfort quotient of the article. In such mattresses forces applied to one side of the mattress can be transmitted to the occupied area. There is no provision for any damping element which could prevent such force transfer (for example by preventing a force applied to the bottom portion or the duckboards of the mattress from affecting the occupied area).

In particular, there is a need for air mattresses of the type which use upholstery material and/or a covering of the type described above and provide a pre-contouring conformation or adaptation to the portions of the body resting thereon as well as providing a damping element to minimize the discomfort caused by force applied to the mattress.
SUMMARY OF THE INVENTION
The premise for this invention is that the air mattress is covered by a suitable upholstery material and/or is equipped with an outer cover allowing it to be utilized as a mattress, or as a pillow for the head or the seat. According to the invention, the resting area is to be made up out of a synthetic material that allows air to pass through freely, or optionally out of a textile material with the same property, which may be covered by a synthetic material which also provides free air penetration.
One technical advantage of the invention derives from the fact that the mattress comprises two chambers: an outer chamber which provides the shape for the contoured occupied area and an inner chamber that serves as support for the outer chamber by maintaining the separation of the inner and outer chambers.

This inner damping element provides yet another advantage: according to the specifications of the invention, it permits the outer occupied area to form a contoured surface.

Thus such a head pillow with a contoured lying surface is of optimal advantage when sleeping on one's back or on one's side.

Another important feature of the invention is the fact that it calls for an occupied surface supported by an outer chamber combined with an inner chamber designed to optimize the effect of the outer chamber.
In a preferred embodiment of the air mattress the outer chamber is inflatable, and could be inflated with a gaseous or liquid medium. In this embodi-ment the inner chamber is separated from the outer chamber in an airtight form. This provides a pillow function between the outer chamber and the airtight inner chamber which is separated from and enclosed by the outer chamber.

The degree of contouring depends on the dimensions of the chambers, particularly the vertical height of the inner chamber and on the points of contact between the outer and inner chambers. If the outer chamber is filled with a certain volume of air, the inner chamber is extended and adapts to the contours of the outer chamber due to the upper and lower connections between the two chambers. In this manner the inner chamber becomes a supporting and damping element which supports the contouring of the outer chamber. In this manner it becomes possible, for example, to use the device as a neck support, in particular as a middle concave neck support which continues on either side into convex forms.
Various club shaped forms can be achieved by the differential aeration of the device.
The same bodily adaptation can be obtained when the mattress is used for lying down, depending on the formation of the inner chamber. In this embodi-ment the spinal column and body can be ideally supported since pressure on the outer chamber results in appropriate pressure changes in the inner chamber, thereby bringing the required support to the spinal column. On the one hand the mattress provides optimal bodily adaptation through contouring when not weighted down and on the other hand, it provides a further adaptation to the body shape since the outer chamber and/or the inner chamber is filled with a gaseous or liquid medium which provides - when weighted down - a proper weight distribution for the bodily parts.
The aeration system also comes into play here, a system which is separate and independent of the contouring system.
The invention therefore provides a combination of the contouring and the aeration systems in the mattress.

The following description describes the use of mattresses where the surface is used for lying, although seating areas of every kind are also possible. As seen in Figures 1 to 3, a head pillow 1 is shown which is mostly made up of upholstery material 2, in which, according to the specifications of the invention, a neck support cushion 3 is incorporated. The integration of the neck support cushion 3 can, for example, occur as seen in Figure 1, which shows the separations 5 of upholstery material 2. In this manner the incorporation 6 of upholstery material 2 becomes possible which can be easily inserted in neck support cushion 3.
To improve support comfort horizontal zippers may be incorporated in upholstery material 2 with slits 4 to provide for improved aeration; the air is expelled by the neck support cushion 3 in an upward direction, is taken up by the horizontal slits 4 and directed toward the neck and the head. Optionally, the segmental horizontal slits 4 in the support surface can be further enlarged in order to reduce lengthwise strain and to provide a softer support area.
The head pillow as best seen in Figure 2 preferably has the shape of a club. Neck contours 8, 8a are adapted to the central area of a person's neck, while contours 7, 7a, 7b are adapted to the lateral parts of the head when he/she lies on his/her side during sleep. As best seen in Figure 3 head pillow 1 is contoured in such a manner that the result is a low head position 11 which merges with a higher neck position 12. Figure 3 also shows that upholstery material 2 can be covered by another material, preferably cover 9, which preferably is composed of a textile material which allows air penetration.
It is important to realize that, according to the degree of inflation of neck support cushion 3, the varying contours 7, 7a, 7b, 8, 8a are the controlling factors for the comfort of the neck as well as for the lateral part of the head. Neck support cushion 3 is prescribed for this purpose. As best seen in Figure 4, outer sleeve 30 defines an airtight outer chamber 15 which can be filled and emptied through valve 31 (see Figure 7).
Inner sleeve 29, which is totally airtight, defines inner chamber 16 and shapes outer chamber 15 although there is no air connection whatsoever between inner chamber 16 and outer chamber 15.
Outer chamber 15 is formed by closures 26 aligned in a lengthwise direction of the resting area while the inner sleeve is formed by closures 27 which are also aligned in a lengthwise direction.
The air supply system of inner chamber 16 is best viewed in Figure 4.
Various air supply systems may be used without departing from the invention.
The air supply system can inflate outer chamber 15 so as to vary the contour of the upper surface. As described earlier the contouring function of the entire upper surface, due to the geometric relationships between inner chamber 16 and outer chamber 15, is positioned between the inner sleeve 29 and outer sleeve 30.
It should be noted here that the connection between inner sleeve 29 and outer sleeve 30 is preferably a double closure so that the inner connection between inner chamber 16 and outer chamber 15 runs the entire length of inner chamber 16.
When the inflation of outer chamber 15 is at a certain level inner sleeve 29 is placed into a stretched form whereby further enlargement of outer chamber 15 becomes impossible. This leads to the separation function of inner chamber 16 and the contour determining function of outer chamber 15. Figure 4 shows a totally inflated condition wherein inner sleeve 29 is in a totally stretched condition. As best seen in Figure 9 the inflation of outer chamber 15 then determines the total height 33 of the mattress or pillow.
Figures 4, 5 and 6 provide examples of the differential heights, although they are not shown in exact scale. For reasons of clarity it must be noted that the height represented by 33 is actually much smaller than the height represented by height 33a. Figure 5 shows outer chamber 15 which is shown in a generally airless condition while Figure 6 shows outer chamber 15 in an airfilled condition so that inner chamber 16 is shown in a consequently distended condition. These conditions can be further appreciated by making a comparison between Figures 5 and 6. Therefore the contouring function depends on the geometric height of inner chamber 16.
Without regard to the inflation system, it now becomes clear that it is not necessary for inner chamber 16 to be connected to the outside air through bore holes 17 and 18. In the absence of these holes, inner chamber 16 could be inflated with a separate valve (not shown). It is also possible to confine the device to either the upper bore holes 17 or the lower bore holes 18. As a further alternative slits 40 could also be installed. The preferred form for slits 40 is a violin key which must be stamped through both inner chamber 16 and outer chamber 15. The advantage of this embodiment is that during the inflation of outer chamber 15 the lengthwise diminution of the pillow can be avoided. A further advantage of slits 40 is that these can be substituted for the usual valve function during inflation.
Inner chamber 16 may also be totally emptied, containing only a minimum of air. Alternatively a valve can be provided to inflate inner chamber 16, or inner chamber 16 can be left with a constant volume of air. As a further alternative inner chamber 16 can be filled not with a gaseous medium but with a liquid one. The inflation of inner chamber 16 according to a preferred embodiment of the invention is best viewed in Figures 4 to 6.
If bore holes 17 and 18 are provided, air can flow through inner chamber 15 to aerate the upper surface as shown in Figure 4. In accordance with the changing weight conditions on the surface area, in accordance with the blow principle, air is drawn in below the bore hole 18 in the direction of arrow 21, and this air is then drawn into inner chamber 16. Should this be changed by a corresponding shift of weight on the surface, then air from the inner chamber 16 will be pushed out through bore hole 17 in line with the direction of arrow 22 and transmitted to the intermediate chamber 14 which is formed by the outer side of outer sleeve 30 and the inner side of cover 9. When air is expelled as a result of a change in weighting, upper bore hole 17 opens up and permits the air in inner chamber to be expelled in an upward direction while at the same time lower bore hole closes. Cover 9 can be opened and removed with zipper closure 13.
The air in airspace 14 is under pressure and is expelled from airspace 14 to the outside through the air permeable cover 9. Cover 9 may contain a replenishment chamber 19. Replenishment chamber 19 can contain a substance, for example healing herbs, cotton wool or a supply of scents which may be covered with ether oil. The forced aeration of replenishment chamber 19 in the direction of arrow 24 brings about the directed dissemination of the scents into the upholstery cover 2 whereby these air currents are directed through slits 4 toward the sleeper's body.
The connection of inner sleeve 29 and outer sleeve 30 is best seen in Figures 5 to 7. Outer sleeve 30 is totally self enclosed and is surrounded throughout by a closure 26. In the interior of outer chamber 15 inner chamber 16 is positioned such that double closures 28 are connected on the inside of outer chamber 15 and along inner sleeve 29 and outer sleeve 30.
Therefore the air in outer chamber 15 eddies around inner sleeve 29 but does not enter inner chamber 16. If outer chamber 15 is inflated, the upper and lower portions of the covering surfaces of outer sleeve 30 assume a certain distance from each other, whereby inner chamber 16, as best seen in Figure 6, is stretched out. Height 33a will hence grow larger than height 33. When outer chamber 15 is fully inflated, inner chamber 16 will be stretched to its maximum height 33a and the contour of the occupied surface is determined at this point. In this manner the total contouring can be determined (for instance the neck pillow can form a club shape).
Viewed over the breadth of neck support cushion 3, the height 33 in the center sections can be chosen to be much smaller than the height of the outer sections of neck pillow 3. This leads to a configuration such that when outer chamber 15 is inflated, outer contours 7, 7a, 7b (as seen in Figure 2) stretch greatly while, for example, the middle portion 8, 8a of neck support cushion 3 stretches only minimally. Therefore inner chamber 16 is thus a bridgelike distancing element which defines the contour of the upper surface of outer chamber 15.
Inner chamber 15 also provides a damping element to neck support cushion 3. If a blow to the outer chamber 30 occurs, inner chamber 15 will provide a degree of damping.
The shape of inner chamber 16 and outer chamber 15, as best seen in Figure 7, provide for contour 32 having a bonelike configuration of neck support cushion 3 as seen in Figure 2.
The aeration effect provided by inner chamber 16 can be further augmented if the entire neck support cushion 3 is attached to the indicated fixture area by holding bags 37 (for instance in cover 2). In this embodiment, the weighting of outer chamber 30 from above (vertical to the plan of the drawing, according to Figure 7, in a downward direction) brings about a compression of the outer chamber 15 as well as the inner chamber 16. Holding bags 37 enable inner chamber 16 to return in every case to its initial level of inflation, as shown in Figure 5, and inner chamber 16 will not fold itself up in a vertical direction. The double closures 28 attaching outer sleeve 30 to inner sleeve 29 also serve this purpose so that the device always remains stable and the contouring of the occupied area returns to its initial position.
Thereby the aeration function of inner chamber 16 in connection with the bore holes 17, 18 is always maintained.
Figures 8 and 9 demonstrate sections of neck support cushion 3 in a partially and almost totally inflated state corresponding to the views provided in Figures 5 and 6. It is again recognizable in Figures 8 and 9 that inner sleeve 29 is connected to outer sleeve 30 with double closure 28 (as seen in Figure 7) and that bore holes 17, 18 penetrate both inner chamber 16 and outer chamber 15 so that the only airtight connection is the connection between inner sleeve 29 and outer sleeve 30 that forms outer chamber 15.
If the outer chamber 15 is inflated to a sufficient degree, inner sleeve 29 also expands up to height 33a as best seen in Figures 6 and 9. This provides a seating cushion contour 10, 10a, lOb, depending on the degree of inflation of outer chamber 15.
Figure 10 provides the invention when used as a mattress to lie on.
Only a few of the elements are shown. It is understood that such surfaces can also be used for seating in conjunction with upholstered furniture, sofas or workchairs, and can also be used as a back pillow. The device shown in Figure 10 is composed of outer sleeve 35 with measurements of, for example, approximately 100 cm x cm with a maximum height of about 10 - 20 cm which can be multiplied in a lengthwise direction with inner sleeves 36. Each inner sleeve has measurements of, for example, approximately 10 cm x 100 cm and a maximum height of about 10 cm -20 cm. Inner sleeves 36 can be tightly integrated with outer cover 35 but they may also be spaced apart by, for example, about 1 cm to 30 cm.
Occupied area 34, as seen in Figure 10, is made up of a multiplication of the configuration shown in Figure 7. Therefore airtight outer sleeves 30 are next to inner chamber 16 which is defined by the previously described inner sleeves 29.
Outer sleeves 30 and inner sleeves 29 are equipped with double closures 28, connecting the tops and bottoms of inner sleeves 29 with the inner surfaces of outer sleeve 30.
The entire outer sleeve 35 is therefore separated from itself in a piece by piece manner. The inner sleeve 36 is placed parallel next to each piece of outer sleeve 35. Each inner sleeve is built up exactly as the previously described as inner sleeve 29 connects to outer sleeve 35 through the previously described double closure 28. It is recognized that double closure 28 follows a different contour so that contouring width 38 and contouring length 39 and occupied surface 34 can be realized.
The inner sleeves 36 may be termed contouring elements (i.e. they are the formation elements which determine and define the inflation status of outer sleeve 35). In this manner the contour of outer sleeve 35 can be given a wide degree of i5 freedom over length 39 and width 38. Consequently the occupied area can be adapted to varying physiques. This is provided by the integrated inner sleeves which create a space between the top and the bottom of the mattress.
In an alternative embodiment of the invention provision is made for inner sleeves 36 to be connected with each other in an airtight manner and separated from outside chamber 15. In this case provision can be made that inner sleeves be inflated with a liquid or gaseous medium at the proper temperature. In this event, the infusion of a liquid at the proper temperature into inner sleeves 36 makes it possible to transfer this temperature to the occupying body. Depending on requirements, the gas or liquid may be cooled or heated. At the same time the inflation can be modulated in such a way as to provide outer. sleeve 35 with excellent orthopaedic support. It is of course understood that outer sleeve 35 can not only be filled with a gaseous medium. A liquid at proper temperature may also be used for this purpose.

The following description describes the use of mattresses where the surface is used for lying, although seating areas of every kind are also possible. As seen in Figures 1 to 3, a head pillow 1 is shown which is mostly made up of upholstery material 2, in which, according to the specifications of the invention, a neck support cushion 3 is incorporated. The integration of the neck support cushion 3 can, for example, occur as seen in Figure 1, which shows the separations 5 of upholstery material 2. In this manner the incorporation 6 of upholstery material 2 becomes possible which can be easily inserted in neck support cushion 3.
To improve support comfort horizontal zippers may be incorporated in upholstery material 2 with slits 4 to provide for improved aeration; the air is expelled by the neck support cushion 3 in an upward direction, is taken up by the horizontal slits 4 and directed toward the neck and the head. Optionally, the segmental horizontal slits 4 in the support surface can be further enlarged in order to reduce lengthwise strain and to provide a softer support area.
The head pillow as best seen in Figure 2 preferably has the shape of a club. Neck contours 8, 8a are adapted to the central area of a person's neck, while contours 7, 7a, 7b are adapted to the lateral parts of the head when he/she lies on his/her side during sleep. As best seen in Figure 3 head pillow 1 is contoured in such a manner that the result is a low head position 11 which merges with a higher neck position 12. Figure 3 also shows that upholstery material 2 can be covered by another material, preferably cover 9, which preferably is composed of a textile material which allows air penetration.
It is important to realize that, according to the degree of inflation of neck support cushion 3, the varying contours 7, 7a, 7b, 8, 8a are the controlling factors for the comfort of the neck as well as for the lateral part of the head. Neck support cushion 3 is prescribed for this purpose. As best seen in Figure 4, outer sleeve 30 defines an airtight outer chamber 15 which can be filled and emptied through valve 31 (see Figure 7).
Inner sleeve 29, which is totally airtight, defines inner chamber 16 and shapes outer chamber 15 although there is no air connection whatsoever between inner chamber 16 and outer chamber 15.
Outer chamber 15 is formed by closures 26 aligned in a lengthwise direction of the resting area while the inner sleeve is formed by closures 27 which are also aligned in a lengthwise direction.
The air supply system of inner chamber 16 is best viewed in Figure 4.
Various air supply systems may be used without departing from the invention.
The air supply system can inflate outer chamber 15 so as to vary the contour of the upper surface. As described earlier the contouring function of the entire upper surface, due to the geometric relationships between inner chamber 16 and outer chamber 15, is positioned between the inner sleeve 29 and outer sleeve 30.
It should be noted here that the connection between inner sleeve 29 and outer sleeve 30 is preferably a double closure so that the inner connection between inner chamber 16 and outer chamber 15 runs the entire length of inner chamber 16.
When the inflation of outer chamber 15 is at a certain level inner sleeve 29 is placed into a stretched form whereby further enlargement of outer chamber 15 becomes impossible. This leads to the separation function of inner chamber 16 and the contour determining function of outer chamber 15. Figure 4 shows a totally inflated condition wherein inner sleeve 29 is in a totally stretched condition. As best seen in Figure 9 the inflation of outer chamber 15 then determines the total height 33 of the mattress or pillow.
Figures 4, 5 and 6 provide examples of the differential heights, although they are not shown in exact scale. For reasons of clarity it must be noted that the height represented by 33 is actually much smaller than the height represented by height 33a. Figure 5 shows outer chamber 15 which is shown in a generally airless condition while Figure 6 shows outer chamber 15 in an airfilled condition so that inner chamber 16 is shown in a consequently distended condition. These conditions can be further appreciated by making a comparison between Figures 5 and 6. Therefore the contouring function depends on the geometric height of inner chamber 16.
Without regard to the inflation system, it now becomes clear that it is not necessary for inner chamber 16 to be connected to the outside air through bore holes 17 and 18. In the absence of these holes, inner chamber 16 could be inflated with a separate valve (not shown). It is also possible to confine the device to either the upper bore holes 17 or the lower bore holes 18. As a further alternative slits 40 could also be installed. The preferred form for slits 40 is a violin key which must be stamped through both inner chamber 16 and outer chamber 15. The advantage of this embodiment is that during the inflation of outer chamber 15 the lengthwise diminution of the pillow can be avoided. A further advantage of slits 40 is that these can be substituted for the usual valve function during inflation.
Inner chamber 16 may also be totally emptied, containing only a minimum of air. Alternatively a valve can be provided to inflate inner chamber 16, or inner chamber 16 can be left with a constant volume of air. As a further alternative inner chamber 16 can be filled not with a gaseous medium but with a liquid one. The inflation of inner chamber 16 according to a preferred embodiment of the invention is best viewed in Figures 4 to 6.
If bore holes 17 and 18 are provided, air can flow through inner chamber 15 to aerate the upper surface as shown in Figure 4. In accordance with the changing weight conditions on the surface area, in accordance with the blow principle, air is drawn in below the bore hole 18 in the direction of arrow 21, and this air is then drawn into inner chamber 16. Should this be changed by a corresponding shift of weight on the surface, then air from the inner chamber 16 will be pushed out through bore hole 17 in line with the direction of arrow 22 and transmitted to the intermediate chamber 14 which is formed by the outer side of outer sleeve 30 and the inner side of cover 9. When air is expelled as a result of a change in weighting, upper bore hole 17 opens up and permits the air in inner chamber to be expelled in an upward direction while at the same time lower bore hole closes. Cover 9 can be opened and removed with zipper closure 13.
The air in airspace 14 is under pressure and is expelled from airspace 14 to the outside through the air permeable cover 9. Cover 9 may contain a replenishment chamber 19. Replenishment chamber 19 can contain a substance, for example healing herbs, cotton wool or a supply of scents which may be covered with ether oil. The forced aeration of replenishment chamber 19 in the direction of arrow 24 brings about the directed dissemination of the scents into the upholstery cover 2 whereby these air currents are directed through slits 4 toward the sleeper's body.
The connection of inner sleeve 29 and outer sleeve 30 is best seen in Figures 5 to 7. Outer sleeve 30 is totally self enclosed and is surrounded throughout by a closure 26. In the interior of outer chamber 15 inner chamber 16 is positioned such that double closures 28 are connected on the inside of outer chamber 15 and along inner sleeve 29 and outer sleeve 30.
Therefore the air in outer chamber 15 eddies around inner sleeve 29 but does not enter inner chamber 16. If outer chamber 15 is inflated, the upper and lower portions of the covering surfaces of outer sleeve 30 assume a certain distance from each other, whereby inner chamber 16, as best seen in Figure 6, is stretched out. Height 33a will hence grow larger than height 33. When outer chamber 15 is fully inflated, inner chamber 16 will be stretched to its maximum height 33a and the contour of the occupied surface is determined at this point. In this manner the total contouring can be determined (for instance the neck pillow can form a club shape).
Viewed over the breadth of neck support cushion 3, the height 33 in the center sections can be chosen to be much smaller than the height of the outer sections of neck pillow 3. This leads to a configuration such that when outer chamber 15 is inflated, outer contours 7, 7a, 7b (as seen in Figure 2) stretch greatly while, for example, the middle portion 8, 8a of neck support cushion 3 stretches only minimally. Therefore inner chamber 16 is thus a bridgelike distancing element which defines the contour of the upper surface of outer chamber 15.
Inner chamber 15 also provides a damping element to neck support cushion 3. If a blow to the outer chamber 30 occurs, inner chamber 15 will provide a degree of damping.
The shape of inner chamber 16 and outer chamber 15, as best seen in Figure 7, provide for contour 32 having a bonelike configuration of neck support cushion 3 as seen in Figure 2.
The aeration effect provided by inner chamber 16 can be further augmented if the entire neck support cushion 3 is attached to the indicated fixture area by holding bags 37 (for instance in cover 2). In this embodiment, the weighting of outer chamber 30 from above (vertical to the plan of the drawing, according to Figure 7, in a downward direction) brings about a compression of the outer chamber 15 as well as the inner chamber 16. Holding bags 37 enable inner chamber 16 to return in every case to its initial level of inflation, as shown in Figure 5, and inner chamber 16 will not fold itself up in a vertical direction. The double closures 28 attaching outer sleeve 30 to inner sleeve 29 also serve this purpose so that the device always remains stable and the contouring of the occupied area returns to its initial position.
Thereby the aeration function of inner chamber 16 in connection with the bore holes 17, 18 is always maintained.
Figures 8 and 9 demonstrate sections of neck support cushion 3 in a partially and almost totally inflated state corresponding to the views provided in Figures 5 and 6. It is again recognizable in Figures 8 and 9 that inner sleeve 29 is connected to outer sleeve 30 with double closure 28 (as seen in Figure 7) and that bore holes 17, 18 penetrate both inner chamber 16 and outer chamber 15 so that the only airtight connection is the connection between inner sleeve 29 and outer sleeve 30 that forms outer chamber 15.
If the outer chamber 15 is inflated to a sufficient degree, inner sleeve 29 also expands up to height 33a as best seen in Figures 6 and 9. This provides a seating cushion contour 10, 10a, lOb, depending on the degree of inflation of outer chamber 15.
Figure 10 provides the invention when used as a mattress to lie on.
Only a few of the elements are shown. It is understood that such surfaces can also be used for seating in conjunction with upholstered furniture, sofas or workchairs, and can also be used as a back pillow. The device shown in Figure 10 is composed of outer sleeve 35 with measurements of, for example, approximately 100 cm x cm with a maximum height of about 10 - 20 cm which can be multiplied in a lengthwise direction with inner sleeves 36. Each inner sleeve has measurements of, for example, approximately 10 cm x 100 cm and a maximum height of about 10 cm -20 cm. Inner sleeves 36 can be tightly integrated with outer cover 35 but they may also be spaced apart by, for example, about 1 cm to 30 cm.
Occupied area 34, as seen in Figure 10, is made up of a multiplication of the configuration shown in Figure 7. Therefore airtight outer sleeves 30 are next to inner chamber 16 which is defined by the previously described inner sleeves 29.
Outer sleeves 30 and inner sleeves 29 are equipped with double closures 28, connecting the tops and bottoms of inner sleeves 29 with the inner surfaces of outer sleeve 30.
The entire outer sleeve 35 is therefore separated from itself in a piece by piece manner. The inner sleeve 36 is placed parallel next to each piece of outer sleeve 35. Each inner sleeve is built up exactly as the previously described as inner sleeve 29 connects to outer sleeve 35 through the previously described double closure 28. It is recognized that double closure 28 follows a different contour so that contouring width 38 and contouring length 39 and occupied surface 34 can be realized.
The inner sleeves 36 may be termed contouring elements (i.e. they are the formation elements which determine and define the inflation status of outer sleeve 35). In this manner the contour of outer sleeve 35 can be given a wide degree of i5 freedom over length 39 and width 38. Consequently the occupied area can be adapted to varying physiques. This is provided by the integrated inner sleeves which create a space between the top and the bottom of the mattress.
In an alternative embodiment of the invention provision is made for inner sleeves 36 to be connected with each other in an airtight manner and separated from outside chamber 15. In this case provision can be made that inner sleeves be inflated with a liquid or gaseous medium at the proper temperature. In this event, the infusion of a liquid at the proper temperature into inner sleeves 36 makes it possible to transfer this temperature to the occupying body. Depending on requirements, the gas or liquid may be cooled or heated. At the same time the inflation can be modulated in such a way as to provide outer. sleeve 35 with excellent orthopaedic support. It is of course understood that outer sleeve 35 can not only be filled with a gaseous medium. A liquid at proper temperature may also be used for this purpose.
If the inner sleeves 36 are filled with liquid and the outer sleeves 35 with gaseous media, we achieve the mattress characteristics of a waterbed, but with distinct orthopaedic adaptive features.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof.
Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
