Abstract: Spring cushions (10) having slow-acting pocketed spring cores (12) characterized by the individual springs of the cores (12) being pocketed within semi-impermeable fabric material and a method of making such pocketed spring cores (12). Fibrous material is located between adjacent rows of pocketed springs and upper and lower sheets are secured to at least some of the strings of springs to reduce noise.

Abstract: An all mechanical support surface that tracks the flotation properties of a true fluid and utilizes a series of constant restoring force springs connecting reciprocating pistons which have supporting surfaces with multiple degrees of freedom to define a user supporting surface that assumes the shape of the user and minimizes the force differential on different areas of the user's skin.

Abstract: A pneumatic and load-supporting spring device for use in bedding, cushions and the like. The disclosed embodiments have tubular telescoping members that are biased apart by either an elastomer located in the overlapping region, or a helical spring located within the pneumatic cylinder formed by the tubes. A conical or dish-shaped head element with clips for securely engaging a typical wire grid found in many bedding products is also disclosed, as well as a dish-shaped head element using cooperating lobe and trough pairs to hold a grid wire therebetween to fix a spring device in place. A foot element is also disclosed for use in attaching a spring device on the base frame of a typical bedding product. The foot element can straddle and snap into a metal frame rail, or be stapled to a frame rail.

Abstract: A pneumatic bumper for a cycle has an inner chamber that is enclosed by collapsible sides. An enveloping cover pneumatically encases the inner chamber and the chamber is vented to allow air to escape in a controlled manner when the sides collapse and the front and back of the bumper are moved towards one another upon impact. The bumper can be secured to the front upright parts of a bicycle and/or motorcycle frame so that the bumper extends, at least in part, ahead of the front wheel of the cycle. The front of the bumper can be provided with an ornamental design or fanciful part to enhance the overall appearance of the bumper.
