Description

BRIEF DESCRIPTION OF DRAWINGS

(1) The invention is further disclosed in more detail by means of exemplary embodiments shown in the drawings, in which FIG. 1 is the plan view of the inflatable element for the first exemplary embodiment of the pad, FIG. 2 is the plan view of the inflatable element for the second exemplary embodiment, FIG. 3 is the plan view of the inflatable element for the third exemplary embodiment, FIG. 4 is the plan view of the inflatable element for the fourth exemplary embodiment, FIG. 5 is the schematic view of the inflated inflatable element for the first or second exemplary embodiment showing the two chambers arranged one above the other, and. FIG. 6 is the plan view of the two chambers of the inflatable element having the same plan shape and positioned side by side.

EXAMPLES OF EMBODIMENTS

(2) 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.

(3) 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.

(4) FIG. 1 shows the plan view of the first exemplary embodiment of the inflatable element 1 for the dynamic-directional seat pad according to this invention. The plan view is substantially rectangular (or slightly trapezoidal) with rounded corners but the lateral sides 2 are concave having the radius of curvature 200 mm and the front side 3 is also concave having the radius of curvature 133 mm. Due to the concave lateral sides 2, the inflatable element 1 in the plan view is narrowed at the front part 15 or it measures 380 mm at the widest point of the back part 14, 400 mm at the widest point of the front part 13 and 350 mm at the narrowest point of the central part 15. Such shape is advantageous from anatomical point of view because the pelvic bone itself is supported during sitting on this pad, while the hips or articulations of the femurs are disposed at least partially outside the pad in areas closely adjacent to the concave lateral sides 2. This contributes to the unintentional straightening of the pad user during sitting and to creating swinging movements to left and right and to front and back.

(5) The back side 4 of the plan view of the inflatable element 1 can be straight or slightly convex.

(6) The inflatable element 1 of FIG. 2 differs from the inflatable element 1 of FIG. 1 in that it consists of two-chambers, wherein both chambers have the above mentioned plan view and are arranged one above the other and are interconnected through the release openings 5 (which are not visible from the top view of the inflatable element 1 but are illustrated in the drawings with an interrupted line). One release opening 5 is arranged in the area of the central line O between the concave lateral sides 2 and on the boundary between the front part 13 and the central part 15, or approximately on the border of the first third of the front part 13 and the central part 15. The other two release openings 5 are arranged in the back part 14 symmetrically with regard to the central line O passing along the concave lateral sides 2.

(7) 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.

(8) 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 FIG. 1 after inflating is 50 to 180 mm.

(9) The pad with the inflatable element 1 from the embodiment of the FIGS. 1 and 2 is particularly suitable for creating muscle activity and direction of this activity into deep stabilizing muscles of the back and abdomen and gluteal muscles.

(10) The embodiment of the inflatable element 1 shown in the FIG. 3 differs from the embodiment of the FIG. 1 or 2 in particular by containing the central reduced area 10 arranged at both sides along the central line O. The central reduced area 10 can have width preferably of 110 mm in the front part 13 to 170 mm in its widest area arranged in the central part 15.

(11) 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.

(12) 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.

(13) The diameter of the release openings 5 is preferably 7 to 12 mm, the most preferably 10 mm.

(14) The maximum height (the height in the direction perpendicular to the plan view shown in the drawing) of the inflatable element 1 of the FIG. 3 after the inflating is 50 to 180 mm.

(15) The pad with the inflatable element 1 from the embodiment of the FIG. 3 is particularly adapted for creating muscle activity and direction of this activity into the deep muscles of the pelvic floor and abdomen and gluteal muscles. Its use is especially suitable for women with gynaecological or urological problems and after gynaecological or urological surgery.

(16) In the embodiment of the FIG. 4, the inflatable element 1 contains a pair of chambers and the central reduced area 10 between them. Each of the chambers is thus arranged between the concave lateral side 2 and the central reduced area 10 wherein the chambers are interconnected through the release opening 5 arranged in the back part 14 on the central line O. Thus the chambers are arranged in the plan view not one above other but side by side.

(17) The diameter of the release openings 5 is preferably 20 to 30 mm, the most preferably 25 mm.

(18) The maximum height (the height in the direction perpendicular to the plan view shown in the drawing) of the inflatable element 1 of the FIG. 4 after inflating is 50 to 140 mm.

(19) The pad with the inflatable element 1 from the embodiment of the FIG. 5, which depicts a schematic view of FIG. 1, can be inflated such that the chambers 25 are arranged one above the other, wherein the plan view of both chambers is the same (as depicted in FIG. 6).

(20) 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.
