Description
BRIEF DESCRIPTION OF DRAWINGS
[0023] The invention is further disclosed in more detail by means of exemplary embodiments shown in the drawings, in which
EXAMPLES OF EMBODIMENTS
[0024] The pad comprises the cover and the inflatable element 1. The inflatable element 1 is arranged inside the cover and comprises the inflatable insert inserted into the cover. The cover of the pad according to the present invention has the same shape as the inflatable element 1. Additionally, the pad can contain the layer of the thermal-insulating foam arranged between the cover and the inflatable element 1 and having the same plan view as the cover of the pad.
[0025] In terms of dimensions, the cover is adequately larger so that the inflatable element 1 could be put into it and stitched inside, optionally also with the same (in terms of plan view) formed thermal-insulating foam, and the same time so that the cover adheres to the content (the inflatable insert and optionally the thermal-insulating foam) inserted into it. The layer from the thermal-insulating foam has adequately smaller dimensions than the cover of the pad to fit into the cover.

[0029] Alternatively, the inflatable element 1 can contain just one release opening 5 which is arranged near the back side 4 of the plan view of the chambers but with spacing therefrom, on the central line O passing between the concave lateral sides 2.
[0030] The diameter of the release openings 5 is preferably 7 to 12 mm, the most preferably 10 mm. The maximum height (the height in the direction perpendicular to the plan view shown in the drawing) of the inflatable element 1 from the

[0032] The embodiment of the inflatable element 1 shown in the
[0033] Between the concave lateral sides 2 and the central part 10, a pair of chambers, identical in the plan view, is arranged one above the other. These chambers are interconnected through the release openings 5 arranged in the front part 13 symmetrically with regard to the central line O. In the back part 14, the chambers are secured by welds 7 which after inflating of the chamber form in the inflatable element 1 recesses which are symmetrical with regard to the central line O. The welds 7 are linear, doubled and pass (in the plan view) obliquely with regard to the central line O so that the end of the weld 7 which is closer to the back side 2 is also closer to the central line O than the second end of the weld 7.
[0034] The central area 10 is in the side view lowered which is achieved either in such way that the central area 10 is not inflatable at all and merely constructively connects the inflatable lateral areas, or the central area 10 is inflatable and is interconnected always with one of the chambers in the lateral area and after inflating its height is lower than that of the lateral areas.
[0035] The diameter of the release openings 5 is preferably 7 to 12 mm, the most preferably 10 mm.

[0042] In all embodiments, the release openings 5 are preferably secured at their edges by reinforcement. It is obvious that even though they are depicted as circular, it is also possible to create different shape, such as oval, square, rectangular, and the like.
[0043] In spite of the fact that several exemplary embodiments have been presented, it is clear, that further possible alternatives exist to these embodiments. Therefore the scope of the patent is not limited to these exemplary embodiments but is given by the definition of the accompanying claims.
