Document Type and Number:
Japanese Patent JPH037177
Kind Code:
A
Abstract:
PURPOSE: To get a ball expanded desirably round with a simple means by applying several walls made of elastic material, of which outer shapes correspond to inner dimension of the air bag and of which circumferences connect with the inner face of the air bag. CONSTITUTION: Outer wall 10 of a round shaped inner air bag is composed of, for example, weld solution polyurethane elastomer. Inside of the air bag 10 are applied two circular walls 11 and 12 at right angle penetrated to each other with a common symmetrical axis 13. The walls 11 and 12 are formed of elastic material identical to that of the air bag 10, of which circumference is solution-welded or vulcanized jointed with the inner wall of the air bag 10. Thanks to the walls 11, 12, inner space of the air bag 10 is partitioned into 4 chambers 14-17 of the same dimension connected to one another by air pressure, having respectively two round cutouts 18, 19 and 20, 21 on the walls 11, 12. Thus, only one air plug 22 is required to inject compressed air into.
