| 101 | Adjustable seat for the handicapped | US220697 | 1980-12-29 | US4367897A | 1983-01-11 | Steven J. Cousins |
| A seat has a shapeable matrix which is constructed of a multiplicity of modular units arranged in longitudinal and transverse rows. The modular units have passageways extending therethrough and contact surfaces which surround open ends of the passageways. Flexible members extend longitudinally through the passageways of the modular units of each row to opposite edges of the matrix. Anchors hold ends of the flexible members to marginal edges of the matrix and tension-applying devices fitted to the members along marginal edges of the matrix allow the modular units to be clamped together so that the contact surfaces are held against one another initially at a pressure allowing the matrix to be contoured to fit selected portions of the human body and subsequently at a greater pressure thereby maintaining the matrix in its contoured shape. | ||||||
| 102 | Musician's chair | US83840 | 1979-10-11 | US4306750A | 1981-12-22 | Jerry A. Wenger; Darrel E. Newell |
| A chair specifically engineered for performing musicians is disclosed. Extensive research and design has produced a vocal or instrumental musician's chair which permits proper diaphragmatic breathing and on which a musician can sit comfortably for long periods of practice or performance. This result is achieved by contouring the seat both for correct performing posture and for comfort. The orientation of the back-rest of the chair to the seat also enhances the posture of the performer and this, in conjunction with the positioning of the body relative to the floor, contributes to the ability of the performer to breathe properly while seated comfortably, thus reducing fatigue and greatly enhancing the tonal quality of the performance. | ||||||
| 103 | Comfort support seat cushion assembly | US813918 | 1977-07-08 | US4132228A | 1979-01-02 | James A. Green |
| A comfort support seat cushion assembly to alleviate discomfort of people that are required to sit for long terms. This comfort support seat cushion provides even pressure distribution on the gluteal region with pressure relief for the ischial tuberosities, coccyx, and perineum. A pulsating means can also be provided to administer therapeutic relief to assist in alleviating discomfort for long term sedentary positions. SUBACKGROUND OF THE INVENTIONThis invention relates in general to a seat cushion assembly for supporting a human body. More particularly, this invention is directed to a comfort support seat cushion assembly that is specifically designed to alleviate discomfort, fatigue, pain, and decreased performance that accompanies long term sedentary positions. In addition, improved blood flow will result from the dynamic action that is part of this invention.It has long been recognized that there have been a multiplicity of contoured chairs, cushions, and seats that have been designed to improve the comfort of those human beings required to sit for long terms. Doctors have always been troubled with the problems of patients that spend long times in wheel chairs. These troubles stem from phlebitis to pressure necrosis, which occurs at points on the body where the bone structure of the patient is close to the supporting surface, such as is the case of the ischial tuberosities. In addition, more recently, biomedical specialists concerned with military aircraft cockpit design have not only noticed that the crew members suffer discomfort, fatigue and pain but also decreased performance efficiency. The lack of adequate support of the back and buttocks both hastens and intensifies the occurrence of these reactions. In the specific case of military aircraft that contains an escape mechanism in the form of an ejection seat, high dynamic forces are generated by the impact of the seat cushion on the buttocks region. Therefore, to alleviate potential spinal injuries, the amount and type of material which can be used between the ischial tuberosities and the seat pan is severely limited.Previous attempts to solve these problems have not recognized the importance of adequate weight distribution across the surfaces of the gluteal region. An inadequate weight distribution will result in excessive pressure on the ischial tuberosities. This is true for both a patient application, such as a wheel chair, and a military aircraft ejection seat application.It has been also recognized that massage in the gluteal region will give temporary therapeutic relief along the contact surfaces to persons who have been required to sit for long terms. A number of devices have been disclosed that produce an intermittent surface pressure variation or pulsating action on the gluteal region. Other devices have been disclosed that produce translational pressure wave movement for massaging effect. One such device is exemplified in the U.S. Pat. No. 3,613,671 to Poor, et al. This patent discloses an inflatable massaging pad which includes a plurality of spaced parallel inflatable cells. An inflation means is provided along with a distributor to produce a translational pressure wave through the cells and a massaging effect.A difficulty with this device is that the translational wave massage pumps the blood flow in both directions, away from the heart as well as toward the heart. The reverse direction, away from the heart, is potentially harmful due to the tendency to further reduce the natural blood flow and increase the potential for phlebitis. This device, therefore, would have little or no therapeutic effect but merely provide some temporary relief to the contact surface.SUMMARY OF THE INVENTIONIt is, therefore, an object of the present invention to provide a comfort support seat cushion assembly that will alleviate discomfort and help eliminate fatigue, pain, and decreased performance efficiency that accompanies long term sitting.It is another object of the present invention to provide means of improving the blood flow in the gluteal region.It is still another object of the present invention to provide a fire resistant comfort support seat assembly tha can also be used in an ejection seat system where high dynamic forces generated by impact during escape limits the amount and type of material that can be used.Briefly, in accordance with the invention, there is provided a seat cushion assembly having a contoured support layer of a firm resilient foam material designed to provide an even pressure distribution over the gluteal region. Pressure relief for the ischial tuberosities is provided in the form of a hole cut in the support layer. Pressure relief for the coccyx is provided in the form of a foam material insert in the support layer. On top of the support layer, a comfort layer of medium resilient foam material is provided. Positioned on top of the comfort layer is a pressure distribution layer of soft foam material with an elongated hole in the central part to provide additional pressure relief for the perineum. A ventilation layer is also provided on top of the weight distribution layer to additionally alleviate discomfort due to increased moisture and body surface temperature. All of the layers are inserted into a porous cloth cover which has a manually operated closure.In another form of the invention, a plurality of inflatable tubes is inserted between the support layer and the comfort layer. The inflatable tubes have an inflating means and a sequencing means which provide transitional waves only from the legs toward the heart to improve the natural blood flow.Other objects and advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings. | ||||||
| 104 | Super-conforming seating system | US698719 | 1976-06-21 | US4114214A | 1978-09-19 | Robert VonHeck |
| An improved variable contour cushion operating system comprising an imperforate flexible casement containing myriad amounts of tiny spherical plastic micro-bearings which displace in response to an occupants body weight during an equalized atmospheric-pressure mode of use, but respond enmasse to an induced low-pressure air differential condition by fixing to an instant position through virtue of said micro-bearings deforming temporarily into inter-joining polyhedrons; wherein said casement in this new disclosure is additionally subjected to a "floative"-mode of operation involving positive air-pressure greater than former ambient-atmosphere, thus achieving an enhanced cradling effect in the "contour"-mode for greater comfort & security to the occupant. | ||||||
