  • Publication number: 20140346718
    Abstract: The mattress assemblies have an array of springs extending from a sheet. Each spring in the array may be manufactured by choosing a position for the spring, cutting a profile of the sheet spring in the sheet, peeling back or bending the profile or tab of the sheet, and shaping the profile to form the sheet spring. The array of springs may be formed from creating a plurality of such springs along rows and columns. In certain embodiments, multiple sheets may be stacked to form the sheet spring array.

  • Patent number: 8720085
    Abstract: Impact attenuating/spring systems may include first and second body portions and at least one spring member at least partially included between the body portions. The spring member(s) may substantially enclose and/or be pivotally engaged with the body portion(s). The components of the impact attenuating and spring element may be arranged such that when a force is applied to the body portion(s), the spring member(s) will exert a counter force to urge the impact attenuating and spring element back toward its original orientation. The spring members may include one or more polymeric element that stretches under a tensile force. The impact attenuating and spring elements may be included in a piece of footwear or other device in a manner such that a user or a retailer (or others) can select an appropriate spring member (or portion thereof), e.g., depending on characteristics of the user or the intended use.

  • Publication number: 20100264571
    Abstract: The system is based on the combination of two parts (1 and 1?) of differing densities with complementary tilted protuberances (2 and 2?), coupled to form a single unit. These protuberances vary in shape, length and thickness so that systems of differing rigidity can be obtained, thus achieving cushioning in virtue of the said protuberances (2 and 2?), enabling the path of the force applied to be defined, thus achieving optimum cushioning force. The system is applicable to both pressure cushioning systems (mattresses, pillows, seats, etc.) and impact cushioning systems (footwear, wheels, helmets, etc.).

  • Patent number: 6647569
    Abstract: A stressable fabric that includes a plurality of layers of multiple materials. A top layer is formed from a generally non-elastic material. Suitable materials for the top layer are fibers, cables, woven material, or any other material that will bend when stress is applied, but that will not stretch. The top layer is attached to a motion axis defining layer made from a plurality of non-compressible blocks. The non-compressible blocks may be rectangular, oval, or other shapes depending on the requirements of a specific application. The shape of the non-compressible blocks defines the directions in which the stressable fabric can easily move.

  • Patent number: 6406009
    Abstract: Composite material spring modules have a fiber reinforced composite material spring body with attachment fittings integrally formed about the spring body. The attachment fittings are molded of a flexible material which dynamically responds to changes in the shape of the spring body upon deflection. Integral formation of the fittings with the spring body provides a unified single piece module which is readily attachable to any structure where spring support is desired. In one embodiment, a mounting foot is configured for mounting of the spring module directly to a planar surface of a supporting frame member by a fastener, or alternatively configured to engage with a frame member without use of a fastener. The composite material spring modules exhibit the properties of stiffness and return to uncompressed state from total depth deflection without set.

  • Patent number: 5720471
    Abstract: A low profile composite material bedding foundation system and methods of manufacture and assembly uses spring modules made of molded composite materials and supported by inner frame members. The low-profile of the spring modules, and the composite material spring property of return to uncompressed state from total depth deflection without set, greatly decreases the height of the bedding foundation in which the spring modules are attached directly to foundation frame members. The small size and simple geometry of the spring modules is especially suited for flexible arrangement and automated assembly of low-profile foundations.
