Description

The invention relates to a pillow with a substantially rectangular form, which pillow is provided with segments with different supporting properties i.e. firmness and/or height, wherein a first segment adjacent to at least the middle of one of the longitudinal sides of the pillow provides great support.
Pillows are used to support the head of a prone person. The conventional pillows consist of a single compartment in which a filling material is arranged. Since the conventional pillows support only the head, improved pillows have been developed with which the neck is also supported. A neck-cushion is arranged for this purpose close to at least one of the longitudinal sides such that the neck-cushion lies between the head and the body of a prone person when this latter rests his head on a part of the pillow which can be compared with a conventional pillow. Such a pillow is described in the German Gebrauchsmuster DE 91 08 786 . The pillow described in this publication is constructed from two main compartments with differing supporting properties separated by a textile partition running substantially parallel to the longitudinal sides of the pillow. These pillows function well as long as the supported person remains lying on his back. Since a person usually turns over many times during a normal night's sleep, the existing pillow with neck-cushion offers too little comfort; a restless sleeper will sleep less well with such a pillow.
The not pre-published international patent application WO 01/24668 discloses a pillow with a substantially rectangular form, provided with segments with different supporting properties, wherein a first segment adjacent to at least the middle of one of the longitudinal sides of the pillow provides great support, wherein a distance from the adjacent longitudinal side of the first segment second segments are situated which provide a greater support than at least one third segment located between the second segments.
The object of the present invention is to provide a pillow of the type stated in the preamble of claim 1 with which the neck can also be supported in addition to the head but which, while retaining the advantages of the prior art, does not have the above described drawbacks.
The invention provides for this purpose a pillow according to claim 1. At a distance from the adjacent longitudinal side of the first segment are situated second segments which provide a greater support than at least one third segment located between the second segments. The first segment will thus be able to support the neck of a person when he is lying on his back, while the head is supported by a conventional part of the pillow. When the person turns over and rests partially on a shoulder, the head moves further from the lying surface. An improved comfort is obtained due to the second segments situated at a distance from the adjacent longitudinal side of the first segment. When the head is turned, the person will rest more on the shoulder, whereby for a pleasant recumbent posture the support of the head will have to be higher. In the supine position the head will after all support on the third segment of the pillow with a relatively limited degree of support (compared to the second segments). Conversely, when lying on the side the head will be displaced further sideward toward the edge of the pillow; the head is herein supported by one of the two second segments instead of by the third segment. The second segment supporting the head provides a greater degree of support and thus compensates (at least partly) the changed optimum distance of the head to the lying surface. This can result in a better sleep pattern and/or less muscular pain. For this purpose the second segments can for instance be given a thicker form than the third segment, they can be filled with a firmer material than the third segment, they can be filled with more material than the third segment, and so on.
The American patent US 5,016,303 describes a head and neck pillow which comprises a top compartment and a base compartment bearing the top compartment. The base compartment is provided with receiving means into which an element manufactured from foam is placed in order to adjust the height and hardness of the pillow. The top compartment can be folded round the base compartment and the pillow can be closed by a zip fastening. The pillow described in this patent also does not provide the functionality of the pillow according to the present invention.
The first segment parallel to the adjacent longitudinal side of the pillow preferably has a width in the order of magnitude of 15 to 37 centimetres. With this width it is possible to realize proper support of the neck of a person in supine position, while when the head turns the jaw remains clear of the first segment. A smaller width gives insufficient support of the neck and a greater width does not leave the jaw free.
The second segments can be coupled to the first segment. The second segments located some distance (preferably a distance of 4-15 centimetres) from the longitudinal side adjacent to the first segment provide the improved support sought when lying on the side. The jaw preferably undergoes as little resistance as possible from the second segments situated adjacently of the third segment and at a distance from the longitudinal side adjacent to the first segment. For simplified production and also to keep the pillow as far as possible in shape over a longer period, the first segment and the second segments can be coupled.
In yet another preferred embodiment the first segment has a greater height close to the adjacent longitudinal side of the pillow than at a distance from the adjacent longitudinal side of the pillow. The decreasing cross-sectional thickness at a greater distance from the longitudinal side adjacent to the first segment has the advantage that an even better fit with the neck can hereby be obtained and even greater comfort is thus provided.
An further improved fit with the human body can also be obtained when the second segments have a greater height than the first segment. Neck and head will after all preferably be situated at a greater distance from a mattress when a person rests on a shoulder than when he is in supine position.
At least one of the segments is preferably formed partially by a shaping element of resilient foam material. Such foam elements are advantageous and can furthermore be placed and held in position in a pillow relatively simply. The material to be used is largely determined by the desired specifications of use of a pillow. Examples are natural latex, polyether and so on.
The pillow according to the invention can be manufactured advantageously since a single shaping element determines the form of the first and third segment. This shaping element herein preferably comprises less material at the position of the third segment than at the position of the first segment. The combination of first and third segment in a single shaping element also results in the advantages already enumerated above. This shaping element can for instance be manufactured from an elongate resilient member, from which a part of the material is removed close to the ends.
The present invention will be further elucidated on the basis of the following figures. Herein:

figure 1 shows a top view of a pillow not according to the invention with schematically designated first, second and third segments,
figure 2 is a perspective view of the pillow shown in figure 1.

Figure 1 shows a pillow 11. A first segment 12 herein has a length which substantially corresponds with the length of pillow 11. First segment 12 is also provided with a projecting part 13 which is situated at about half the length. The projecting part 13 is situated on the side of the first segment 12 remote from longitudinal side 2. When a person is in supine position the neck can be firmly supported over a greater length than the neck of a person in side position; a greater length of support of the neck in side position results in a disagreeable engagement of the first segment 12 on the jaw of the prone person. Second segments 14 and third segment 15 can continue up to the longitudinal side 2 of pillow 11 located at a distance from first segment 12. While segments 14 and 15 can be formed by inserting support bodies into the pillow, they may also be formed by separate compartments of the pillow 11.
Figure 2 shows a partly cut-away view of a pillow 11 as shown in top view in figure 1. The first segment 12 with projecting part 13 is manufactured from a shaping body. The second segments 14 and third segment 15 are formed by compartments of pillow 11 which for this purpose are separated from each other by means of partitions 23. Pillow 11 is obtained by filling the second compartments 14 with more or firmer filling material than third segment 15.
An embodiment of a pillow according to the invention comprises the pillow 11 wherein a single shaping element determines the form of the first and third segment 12,15 which are thus embodied integrally.
Although the invention is described on the basis of only one embodiment, it will be apparent to all that the present invention is by no means limited to the described embodiment. On the contrary, many more variations are possible for a skilled person within the scope of the invention. Segments can thus transpose gradually into each other, the form of the shaping elements can be varied and it is possible to manufacture shaping elements from a plurality of materials with varying resilience characteristics, opposite longitudinal sides of a pillow can both also be provided with an adjacent first segment, whereby the pillow can be used on two sides.
