Description

There are already inflatable seat cushion in countless versions, these are already from the medical field z. B. ( DE 20 2013 005 094 U1 ) known. Inflatable seat cushions are also made of z. B. the field of office chairs ( DE 20 2015 100 101 U1 ) known, but only as integrated into the chair variant and thus neither portable, nor on other seating options such. As aircraft seat, train seat or bus seat and other hard seats z. B. applicable at school or in universities. There are already several approaches half-sitting to travel to be able to carry more passengers in an airplane or train, as well as on the bus. Airlines need to move more efficiently in order to stay competitive in price dumping. For these reasons, these seats are getting easier and easier. Often to the detriment of seating comfort, especially on several hours of travel. Similarly, many students have problems on some padless wooden chairs to spend hundreds of hours in countless lectures with sometimes severe pain while sitting. Even with physical limitations, such. As obese or handicapped people who sit more often or even need to sit constantly, the inflatable seat cushion described in the next paragraph can help to sit more comfortably.

It is important to make the pillow as small and light as possible in order to use it in any kind of travel. This means that the pillow is filled with gaseous media, such as breathing air and can be emptied and folded in the unused state, in order to minimize the space required in travel or hand luggage. It is equally important to make the pillow so as to avoid falling limbs, as well as possible circulatory disorders. For this purpose, the cushion needs a special design, which not only relieves the tailbone, but also the buttocks (seat legs) and the rear thigh muscles.

The specified in the protection claim 1 invention is based on the problem to provide a seat cushion which has one or more chambers. However, with normally inflatable seat cushions, one or more valves are required, via which the chambers must be filled with the mouth. In the present cushion is a kind of foam made of polyurethane or other possible types of foam, which is compressed when folding the seat cushion. When opening the valves, the foam tends to unfold, thereby the air is sucked in until it is completely filled.

The problem is solved with the features listed in the protection claim 1.

With the invention is achieved to extremely improve the comfort during long trips, as well as possibly health restrictions and damage caused by circulatory disorders of the lower body. Due to the self-inflating function, it is not necessary to blow the air over the mouth, or the valves, which results in a considerable ease of use, as well as important hygienic advantages. The pillow is in the unused condition very small collapsible and light.

An advantageous embodiment of the invention is shown in the claims 4 and 5, here is ensured by various recesses in the cushion, the discharge of the seat legs and tailbone.

An embodiment of the invention will be described with reference to 1 and 2 explained. Show it:

1 The seat cushion with multi-chamber system, description of the functional areas

2 The seat cushion with 3-compartment multi-chamber system in 3-dimensional view

The 1 and 2 show the seat cushion with a filling area ( 1 ) and the recesses ( 3 . 4 ) to relieve the body parts. If the recesses ( 3 ) are inserted obliquely, the pillow is also suitable for children. Centering ( 5 ) prevents lateral slipping. About the valve ( 2 ), the seat cushion can be filled arbitrarily. The separating seams ( 6 ) contribute to the stabilization of shape and help with tempering and air circulation. In order to not have to endure unpleasant forces when sitting on one side, or obliquely, there is a further separating seam in the middle between the two recesses for the seat legs ( 6 ) as well as an overflow channel ( 7 ), which compensates for the possibly different pressure slowly.
