| 257 | Pneumatic furniture | US985647 | 1992-12-07 | US5423094A | 1995-06-13 | Michael J. Arsenault; Joseph Arsenault |
| A variety of pneumatic and other components assembled to afford comfort not found in conventional furniture as follows: a pneumatic cushion exchanging air through a bladder support into two independent bladders where upon depression by persons or other subsequence weight applied to the cushion evenly supports the weight applied. The inner and outer bladder operate independently receiving and compressing air through the cushion and bladder air transfer valves. This independent action allows frontal support when weight is applied to the frontal areas only. In addition to the frontal support a molded plastic material termed herein as the bladder support having memory after thermal molding offers additional front support when weight is applied. When weight or a person is fully seated both bladders are expanded as the air is expelled from the cushion through two air valves serving each of two independent bladders offering uniform seating support. The supporting structure for the bladder support, bladders, and cushion being a composite substrate with properties allowing a depression value allowing additional flex when weight is applied. | ||||||
| 258 | Inflatable booster seat | US137945 | 1993-10-15 | US5333336A | 1994-08-02 | Robin L. Langsam |
| A booster seat for use by a child at an event, e.g., a movie, a theater production, a professional baseball game, etc. The booster seat can be selectively inflated at the intended seat site and, after the event is viewed by the child, can be quickly deflated and folded into an envelope for subsequent ease of carrying and reuse. In one form of the device the inflatable booster seat comprises two separate inflatable chambers. The child has the choice then of being raised either the full intended height of the booster seat (both chambers inflated) or, alternatively, by inflating one or the other chamber, the child can be raised up a portion of the total two-chamber height. An air inlet valve for each chamber is provided to facilitate inflating by the child or the custodial adult then accompanying the child to the event. To facilitate ease of deflation, one or more selectively openable air outlet valves are provided. In a simple version of the device, the air inlet valve is the same as the air outlet valve. A mechanical inflation valve or mechanism can be provided to ease inflation. | ||||||
| 259 | Waterblown foam base | US975848 | 1992-11-13 | US5317773A | 1994-06-07 | Robert H. Graebe |

| 260 | Sealed composite cushion having multiple indentation force deflection zones | US977136 | 1992-11-16 | US5282286A | 1994-02-01 | Michael MacLeish |
| A sealable, composite cushion is disclosed having a plurality of resilient support member horizontally disposed to one another and surrounded by a fluid impervious membrane. Each resilient support member has a known Indentation Force Deflection (IFD) value and is located in the cushion based upon medical criteria to provide zones of varying support. In an embodiment, the resilient members are bonded to the membrane and act as tension members to maintain the cushion's form while under a load. As a result, the cushion resists further deflection not only by the resilient members' resistance to compression, but also by an increased internal pressure. Accordingly, the cushion of the present invention is a composite of fluid flotation and compression resistance. A valve may be incorporated into the cushion to regulate the fluid floatation characteristics of the cushion or to assist in its transportation. In another embodiment, the resilient support members are not bonded to an upper membrane portion, thereby decreasing shear forces acting upon the resilient members when the cushion is under load. Further, excess membrane may be located at the cushion periphery. When subject to a load, this excess membrane material can migrate to the upper portion of the cushion, thereby decreasing undesirable peripheral distortion of the cushion. | ||||||
