Abstract
A body support includes at least one self-inflating fluid cell. Each of the at least one self-inflating fluid cell contains a reforming element. The body support further includes a blow-off valve attached to the at least one self-inflating fluid cell or a manifold system interconnecting the at least one self-inflating fluid cells. The blow-off valve opens at a blow-off pressure that is higher than a maximum working pressure that occurs when the body support is supporting the maximum weight limit.
Claims23
A body support configured to support a weight up to a maximum weight limit, the body support comprising:
- at least one self-inflating fluid cell, each of the at least one self-inflating fluid cell containing a reforming element;
- a blow-off valve attached to the at least one self-inflating fluid cell or a manifold system interconnecting the at least one self-inflating fluid cells, wherein the blow-off valve opens at a blow-off pressure that is higher than a maximum working pressure that occurs when the body support is supporting the maximum weight limit.
A method of packing a body support configured to support a weight up to a maximum weight limit comprising:
- providing the body support, the body support including:
- at least one self-inflating fluid cell, each of the at least one self-inflating fluid cell containing a reforming element;
- a blow-off valve attached to the at least one self-inflating fluid cell or a manifold system interconnecting the at least one self-inflating fluid cell, wherein the blow-off valve opens at a blow-off pressure that is higher than a maximum working pressure that occurs when the body support is supporting the maximum weight limit;
- compressing the body support with a compression machine to open the blow-off valve;
- and
- removing fluid through the blow-off valve from the at least one self-inflating fluid cell during the compressing.
A body support comprising:
- at least one self-inflating fluid cell containing a reforming element, each of the at least one self-inflating fluid cell containing a reforming element;
- at least one pressure relief valve operably attached to the at least one self-inflating fluid cell or a manifold interconnecting the at least one self-inflating fluid cell, the at least one pressure relief valve configured to be controllable to allow for a maximum operable pressure level to be maintained within the at least one self-inflating fluid cell during body support use;
- and
- a blow-off valve attached to the at least one self-inflating fluid cell or the manifold system, wherein the blow-off valve opens at a blow-off pressure that is higher than the maximum operable pressure level.
