| 20130139321 | RESILIENT GRID FOR USE WITH CELLULAR CUSHIONS - A resilient grid ( | 06-06-2013 |
| 20120326482 | WHEELCHAIR BACK MOUNTING ASSEMBLY - A support mechanism ( | 12-27-2012 |
| 20120292958 | MOTORCYCLE SEAT CUSHION - A motorcycle seat cushion comprising a base with an array of upstanding air cells across the base. In one aspect, the air cells are interconnected such that pressure is spread cross a wider area to reduce pressure points. There are external air flow pathways between the cells that allow air to circulate among the cells to disperse heat and moisture. There is a midline pathway that is positioned under the perineum and coccyx of the rider to provide pressure relief to the perineum, prostate and coccyx of the male rider. In one aspect, the cushion includes a cover having top and side walls of the cover constructed from a two-way stretch material. The cover has air vents that functionally align with at least some of the air flow pathways to promote the flow of ambient air into the air flow pathways. | 11-22-2012 |
| 20120091300 | WHEELCHAIR BACK MOUNTING ASSEMBLY - An adjustment apparatus ( | 04-19-2012 |
| 20120036646 | INFLATABLE CELLULAR MATTRESS WITH ALTERNATING ZONES OF INFLATED CELLS - A cushion or mattress comprising a base and a plurality of linearly aligned individual air cells across the base. Groups of individual air cells can be interconnected and in fluid cooperation with an inflation source, such as a pump. In one aspect of the invention, the inflation of adjacent cells is staggered, for example, in a checkerboard-like inflation pattern that helps diffuse load over a wider area. | 02-16-2012 |
| 20120007396 | Supportive Back Overlay for Wheelchair Back - A supportive back rest for attachment to an original equipment back rest of a wheelchair to enhance the supportive characteristics of the wheelchair back rest. The supportive back rest includes a cushion, a suspension element and a cover. The cushion and one side of the suspension element are positioned in the cover. An opposed side of the suspension element is exposed and defines a space between it and the cushion. The suspension element slips over the upper edge of the original equipment back rest of the wheelchair to suspend the supportive back rest in position behind a seated user. The suspension element can be attached to the cover or can be attached to the cushion by molding or through attachment anchors. | 01-12-2012 |
| 20110258783 | INFLATABLE CUSHION VALVE AND ATTACHMENT APPARATUS - An attachment apparatus ( | 10-27-2011 |
| 20110209287 | PROXIMITY SENSOR - An immersion sensor for use with a cushion or mattress for determining the relative immersion of a person within the cushion or mattress comprising a sensor, a ground and a circuit for measuring capacitance. The sensor comprises a sheet of conductive material, and the ground comprises a second sheet of conductive material. The circuit is adapted to send short bursts of electrical current to the sensor and a capacitor. The circuit is further adapted to measure the length of time the burst of current takes to charge the capacitor. Based upon the measured time, the circuit calculates the proximity of the object based upon the time taken to charge the capacitor. A method that may be implemented with the immersion sensor is also disclosed. | 09-01-2011 |
