Definitions

  • the invention relates to a sleeping bag with a covering, a warming filling arranged in the covering and an air cushion serving as a cushion.
  • DE-AS 2 516 781 describes a sleeping bag for camping outdoors with a waterproof outer material, a body-friendly inner material and a warming filling, the outer material in the back area being completely separated from the warming inner part and the warming inner part made of body-friendly inner material, one Filling and an intermediate material and these three layers are connected to one another by quilting seams, in the filling a hose arranged in several layers next to one another is provided as a cushion.
  • This sleeping bag has the disadvantage that the production is relatively complex and the possible uses of the sleeping bag are limited.
  • the invention is therefore based on the object of providing a sleeping bag which can be produced easily and cheaply, which can be easily repaired by the user himself if individual parts are damaged and which is suitable for a wide variety of applications, e.g. can be used as a sleeping bag, as a sleeping pad for individuals and for two people both outdoors and in the apartment.
  • a sleeping bag of the type mentioned at the outset which is characterized in that the air cushion consists of replaceable, inflatable tubes which can be inserted directly into the filling or between separate filling layers.
  • the sleeping bag according to the invention or the sleeping pad according to the invention has the advantage that the hoses serving as support pads can be arranged individually and are interchangeable, so that the hoses can be incorporated into the filling during the production of the sleeping bag or that the hoses can also be used after the production of the sleeping bag can be inserted into the filling.
  • Another significant advantage of the sleeping bag according to the invention is that the sleeping bag can not only be manufactured in a simple manner, but can also be easily repaired if a hose is damaged. In this case, the individual hose is either repaired or replaced with a new hose. It is not necessary that the sleeping bag or sleeping pad be sent to the manufacturer for repair.
  • the sleeping bag according to the invention not only serves as a bedspread, but at the same time also as a cushioning pad against uneven floors. Since the hoses can be made from thin materials, the weight of the hoses serving as support pads hardly plays a role, and in this way a sleeping bag is provided which at the same time fulfills the function of an air mattress, without the additional weight of an air mattress and the cumbersome Handling an air mattress must be accepted.
  • the sleeping bag according to the invention can e.g. can be converted into a double bed by equipping it with an all-round zipper, which can be rolled up into a small roll when not in use and can thus also be accommodated in small residential units.
  • the hoses serving as support pads, which are arranged in the filling or between individual filling layers, are preferably arranged individually, and each hose is preferably equipped with a separate valve for inflation. It may also be advantageous to connect at least some of the tubes to one another via inflatable connecting webs, in which case only one valve is used to inflate the tubes connected to one another.
  • the valves for inflating the hoses suitably consist of flip-over valves or stopper valves.
  • the hoses are made of the thinnest possible, highly elastic material, e.g. made of plastic, in particular PVC.
  • the hoses can be connected to one another via webs made of flexible plastic.
  • the bars can be replaced if necessary.
  • the tubes are preferably arranged in the direction of the quilting seams of the sleeping bag.
  • the tubes can be arranged in the longitudinal direction of the sleeping bag, but also transversely or obliquely to the longitudinal direction of the sleeping bag.
  • the replaceable, inflatable tube has at least one stiffening web on the inside, which divides the tube into a multi-chamber system.
  • the stiffening web (s) can be arranged vertically or horizontally within the hose.
  • the stiffening webs preferably extend over the entire length of the hose, the upper and lower ends of the web possibly also being connected to the end part of the hose, so that separate, separate chambers are created which can be inflated by separate valves.
  • the chambers communicate with one another via passages, so that only one valve is required to inflate a tube, which is arranged at the end which is assigned to the foot end or the head end of the sleeping bag, so that the hose inserted into the sleeping bag can be inflated without having to pull the hose out of the sleeping bag.
  • the webs serve to give the tubes a higher stability, so that the tubes can be inserted more easily into the sleeping bag and that the tubes are not compressed by the body weight of the user of the sleeping bag when inflated.
  • the preferred cross-sectional shape of the air hose is an 8-shaped cross-section.
  • the tubes which can be inserted into the filling or between the filling layers can be designed in such a way that the cross section is widened at one end of the tube, this end being preferably arranged in the head end of the sleeping bag, so that an elevated base is provided in the head part of the sleeping bag is forming.
  • the cross-section of the hose is in this case designed so that the cross-section rises slightly up to the end of the hose, so that an oblique base is formed.
  • the second end of the tube with a somewhat enlarged cross-section, so that an increased boundary surface is formed at the foot end of the sleeping bag and in this way a certain boundary surface or holding surface at the foot end of the sleeping bag is formed by the hoses arranged side by side.
  • the formation of the tubes with an enlarged cross-section at the head end and at the foot end has the particular advantage that the person resting on the bedding of the sleeping bag does not slide down from the sleeping bag while sleeping and at the same time an elevated head bed is formed at the upper end.
  • the sleeping bag consists of a plurality of filling layers which are arranged one above the other, the filling material being enclosed in each case by two webs, preferably made of an air-permeable material.

  • the arrangement of the filling material in webs which are connected to one another by quilting seams has the advantage that the hoses are particularly easy to use, which is why they are manufactured facilitated, and thus the replacement of individual hoses can be made particularly easily.
  • the webs that envelop the filling material are connected to one another at the outer edges by means of seams, and at the foot end the webs are preferably connected by a releasable fastener, in particular by a Velcro fastener or by a zip fastener.
  • This closure serves to open the webs so that the hoses, which serve as air cushions, can be pushed into the sleeping bag underlay and can be replaced during repair work.
  • the top and bottom layers of the sleeping bag are e.g. connected to each other via a releasable closure, e.g. via a zipper or a Velcro fastener.
  • a head part is preferably provided, which can be designed in the form of a hood or also in a rectangular shape.
  • the head part of the sleeping bag can be detached with the sleeping bag, e.g. via a zipper or a Velcro fastener.
