FIELD: mechanics. ^ SUBSTANCE: pneumatic support incorporates a flexible cylinder air bag with the base having, at least, one hole to force air into the bag. The branches of, at least, one zipper fastener branches are fastened spaced apart and perpendicular to or at an angle to the support lengthwise axis on the bag outer side. The zipper fasteners are bent in opposite directions from the lengthwise axis of the fastener in non-operating position and are engaged in the operating position. The length of every branch in non-operating fastener position has been selected from the condition L=(0.57.5) P, where L is the fastener branch length, and P is the length of the cylindrical support in its cross-section. ^ EFFECT: expanded pneumatic support performances. ^ 2 cl, 13 dwg |
