Abstract

A down quilt is composed of quilted filled compartments, a first group of which is arranged in the edge region (R) of the quilt. Toward the centre of the quilt, the first group is delimited by a base seam (A) from a second group is delimited by a base seam (A) from a second group of compartments which form a body contour region (K). The base seam (A) follows a curve which has approximately the same proportions as the contours of the recumbent human body. When the quilt is in use, a ''sleeping hole'' which matches the shape of the sleeper's body is automatically formed. When in use, the quilt provides more uniform insulation, which improves its overall comfort.

Description

QUILTED CEILING

The invention relates to a quilt with quilted chambers, which are provided with an insulating, heat and moisture compensating filling.

Good bedding is largely determined by the quality of the coverlet. The insulation values of the ceiling and the ability to regulate temperature and humidity are of crucial importance for subjective well-being. According to the current state of knowledge, the filling quantity, ie the weight of a blanket, is less responsible for the thermal insulation than the volume of the air cushion, which is formed by the filling material used in the smallest air chambers. The lighter the material with which the desired air cushion can be achieved, the more comfortable the ceiling is classified. Various filling materials are used to achieve the desired regulation and insulation properties, whereby natural down from ducks and geese has proven to be a particularly pleasant filling material. The general increase in comfort in the living area and the associated higher bedroom temperatures have led to the development of blankets of ever lighter qualities, with the finest down fillings of approx. 200 to 300 g / m ^ for a normally large body blanket as an example of a modern, light one Cover apply. So that such a small amount of spring does not shift uncontrollably within the socket and condenses at certain points, leads to an increased sensation of heat there, and is thinned at other points so that there is a risk of hypothermia in certain parts of the body attached, which prevent a large displacement of the filling in the socket.

Systematic measurement series for recording the insulation values and the thermophysiological behavior of such blankets have shown, among other things, that quilted blankets have slight insulation cracks along the stitching seams, which can be perceived as uncomfortable if they are on sensitive parts of the body, e.g. come to rest on the joints. Furthermore, the series of measurements have provided surprising insights into a sleep-promoting bed climate. The results of these measurements form the starting point for the present invention.

The object of the present invention is therefore to improve the overall comfort behavior of a quilted bedspread. Seasonal climate fluctuations should also be compensated for. According to the invention, these objects are achieved by features defined in claims.

The choice of the quilted pattern inevitably results in a "sleeping cavity" adapted to the body shape of the sleeper. As a result, the volume of the insulating air layers under the blanket is at least roughly determined and is no longer left to chance depending on the current behavior of the sleeper. This results in reasonably constant insulation values when using the ceiling. The quilting seams, at which a certain jump in insulation occurs, are preferably laid in such a way that they have practically no influence on the well-being of the sleeper. For example, avoided that the quilting seams come to rest on the joint parts of the body. Large flakes of higher quality are preferably used as the optimal filling material. The measurement series for this filling quality showed surprisingly better thermal insulation values than for the finest down, as well as a superior water vapor absorption capacity. This ensures an optimally balanced, body-friendly microclimate under the covers.

Details and further advantages of the invention will appear from the following description. Preferred exemplary embodiments are explained in more detail with the aid of the drawings. Show it: 1 shows the example of a quilt with an arrangement of the chambers adapted to the body shape,

2 shows another embodiment, and

3 shows the water vapor transmission index IMT of different quilt patterns.

The ceiling shown in FIG. 1 represents one of a large number of conceivable exemplary embodiments. The principle of the invention is first to be explained using this example.

The blanket 1 shown is provided with various quilting seams, through which a system of chambers is formed. Line A occupies a special position under the stitching. It separates a body profile area K from an outer edge area R of the ceiling 1 within the system of the chambers. The line A follows a curve which is based on proportions of the human body: a pattern with a wider upper shoulder area appears on the flat ceiling 11, a slightly narrower central region 12 adjoining at the bottom, finally an increasingly narrower leg region 13 and a narrowest part that closes the body profile region K downwards, the foot region 14. The upper boundary of the shoulder region 11 has a gently downwards in the center drawn recess 15 for the head. The mentioned areas 11, 12, 13 and 14 are separated from one another by quilting seams 21, 22 and 23. The quilting seams are preferably curved, specifically the upper quilting seam 21 and the lower quilting seam 23 are approximately parallel to the upper boundary line for the recess 15. The middle quilting seam 22 can either be curved in the same or in the opposite sense.

In the edge region R, the above-mentioned stitching seams 21, 22, 23 are continued. Starting from line A, the seams are guided there at approximately a right angle to the outer edge of the ceiling. Furthermore, in all four corner areas of the blanket, approximately diagonal quilting seams 31, 32, 33 and 34 are made in the example from the area of the outer edge of the blanket to line A. In the example, these topstitchings are supplemented by two stitching seams 35, 36 running parallel to the main axis X-X of the ceiling in the upper part of the edge region R and a central stitching seam 37 in the lower part of the edge region R.

As indicated in FIG. 1, the quilting seams, in particular seams 22 and 23, can also have a different course or a different shape from the example shown. The decisive factor is the effect achieved with the stitching, namely the formation of a "sleeping cavity" in the body profile area K, the sleeping cavity being approximated by the shape of the body. end of line A is limited. In the peripheral area R adjoining the outside, the sleeping cavity is sealed off by the practically flat lying of the edge chambers formed by the stitching seams. In addition, when the sleeping cavity is "erected", the edge chambers exert a certain support function on the central chambers, so that an at least roughly determined air cushion is formed between the sleeper and the blanket, which has a stabilizing influence on the heat-insulating properties of the blanket. The quilting pattern described supports in particular the pliability of the blanket with respect to the sleeper and in the edge area with respect to the underlay.

FIG. 2 shows a further exemplary embodiment, according to which the blanket has a larger number of chambers than in the example according to FIG. 1. Thus, two middle regions 12A, 12B are provided in FIG. 2, the region 12A due to the stitched seam 21A is separated from the upper shoulder region 11. Another quilting seam 21B separates the chambers of the two middle regions 12A, 12B from one another. In this example, the stitching seams 21B and 22 are not continued directly in the edge region R, but are replaced by a common edge stitching seam 40 lying between them. Furthermore, the central edge stitching 37 according to FIG. 1 is replaced by two lower edge stitching 38, 39 in FIG. 2. The formation of the "sleeping cave" mentioned is additionally supported by the larger number of quilting seams. Due to the formation of the sleeping cavity and the associated effect of the air cushion formed below, relatively small fillings in the chambers are sufficient to achieve optimal comfort behavior of the ceiling. Typical filling quantities are approx. 200 to 300 g / m ^* -. From the comparison measurements mentioned, a large flake down quality has proven to be the optimal filling material for the described blanket filling. This filling not only results in optimal insulation values, but it also has a superior water vapor absorption capacity, which results in a more balanced microclimate under the blanket.

3 shows the superior properties of a blanket produced according to the described features compared to conventional blankets. The figure shows the water vapor transmission index IMT of various fabrics, which are designated as patterns 1 to 6. Patterns 1 and 4 contained a down / feather blend, Patterns 2 and 5 a filling of the quality "Asian new pure goose down, white 90" and Patterns 3 and 6 a filling of the quality "Polish new pure goose down Ia, white, 90% ".

With the help of a thermoregulation model of human skin, thermophysiological tests were carried out in a measuring device that simulates both dry and sweaty skin. logical characteristic data determined, whereby the measuring apparatus and the measuring procedure are specified in DIN 54 101 Tl. The water vapor transmission index, which expresses the relative water vapor transport capacity of the quilt patterns based on the thermal insulation, was determined from the measurement of the thermal resistance and the water vapor resistance. The higher the index value, the more favorable it is to be assessed, since this indicates a better water vapor transport capacity with the same thermal insulation.

The results of these measurements shown in FIG. 3 show that of the samples 1, 2, 3 with the same filling quantity of 400, the samples 2 and 3 have a particularly favorable index. Increasing the fill quantity from pattern 1 to pattern 4 has a slightly positive effect on the index. Conversely, due to the reduction in the filling quantity, the index for samples 5 and 6 is lower and therefore not as physiologically favorable as for samples 2 and 3 with a higher filling quantity. From experience, certain general assessment criteria have emerged for a differentiating assessment of the relative water vapor transport capacity of quilts, which are expressed by four areas "very good, good, satisfactory and unsatisfactory" in the ordinate of the representation according to FIG. 2. If these criteria are taken as the basis, the relative water transport capacity of the samples with a filling quantity of 400 g / rτr Pattern 1 as satisfactory and that of Patterns 2 and 3 as very good. For the filling of the quilted chambers in the ceiling described above, fillings according to patterns 2 and 3 were selected.

In individual cases it may be advantageous to use certain chambers, e.g. to provide those of the body profile region K with a different relative filling quantity than the chambers of the peripheral region R. Also the chambers within a region, e.g. Within the body profile area K, different fillings can be used to isolate different parts of the body, such as the shoulder area, abdominal region, or leg or foot areas, differently.

The blanket described can advantageously be combined with a further blanket, the specific filling weights being selected such that a lighter summer blanket, a second transition blanket and, by connecting both blankets, for example by buttoning, one that is warmer overall Winter blanket combination results. The stitching seams of the second blanket are preferably positioned in such a way that they do not come to rest on the stitching seams of the first blanket, but rather fall on their chamber areas when the two blankets are connected to one another. In conclusion, it should be pointed out that the "stitching" can also be stapling, which can be formed, for example, by web constructions or by thermofixation or by a combination of different methods in order to define the chambers described, which are used in the Using the blanket leads to the formation of the "sleeping cave" mentioned. Such subdivisions also do not have to consist of continuous stitching, filing or the like. Rather, these subdivisions can be applied discontinuously, for example in order to match the insulation effect in the area of the filing to the values in the area of the chambers, or to facilitate the filling process of the chambers.
