Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This application claims the benefit of U.S. Provisional Application No. 60/522,131 (Attorney Docket No. YAALP2004-13) filed on Aug. 19, 2004, which is herein incorporated by reference for all purposes. FIELD OF THE INVENTION [0002] The present invention relates to a cushion or a bed which includes dynamic support. BACKGROUND OF THE INVENTION [0003] Conventional massaging beds or chairs employ rollers to replicate massaging motions. The rollers typically move along the vertical axis of the spine to apply pressure, thereby relieving tension in the muscles. Since rollers move in a fixed line, they may not conform to the body contour, thus insufficiently contacting the body to adequately relieve tension in the muscles. Additionally, the use of rollers does not provide adequate support for the spine. [0004] From the foregoing discussion, it is desirable to provide an improved cushion which avoids the disadvantages of rollers. SUMMARY OF THE INVENTION [0005] The present invention relates to a cushion which relieves tension in the muscles. In one embodiment, the cushion includes a frame on which a support pad unit is mounted. The support pad unit comprises a plurality of support pads, wherein at least one of the support pads are movable in the vertical or z direction relative to the plane formed by the plurality of support pads. [0006] In one embodiment, the support pads are separated into first and second groups of support pads. The first group of support pads is movable while the second group is immovable. The first group of support pads can be commonly coupled to move as a group. BRIEF DESCRIPTION OF THE DRAWINGS [0007] FIGS. 1a-b show an embodiment of the invention; [0008] FIGS. 2a-b show the operation of one embodiment of the invention; [0009] FIGS. 3a-b show an alternative embodiment of the invention; [0010] FIG. 4 shows another embodiment of the invention; [0011] FIG. 5 shows a movable support pad in accordance with one embodiment of the invention; [0012] FIG. 6 shows another embodiment of the invention; [0013] FIGS. 7-8 show yet another embodiment of the invention; [0014] FIGS. 8a-b show an embodiment of a pad unit; [0015] FIG. 9 shows an embodiment of a pad unit and actuator; [0016] FIGS. 10a-b show various embodiments of support pads in accordance with the invention; and [0017] FIGS. 11-13 show various embodiments of massaging subunits. DETAILED DESCRIPTION OF THE INVENTION [0018] FIGS. 1a-b show top and cross-sectional views of one embodiment of the invention. As shown, a cushion 101 includes a frame 120. The frame can be formed using, for example, steel. Other rigid materials, such as aluminum, can also be used. Mounted on the frame is a plurality of support pads 130.sub.1-x. Illustratively, five pads (x=5) are mounted on the frame. Providing other values of x is also useful. [0019] A protective cushion layer 190 can be provided to surround the frame and support pads. The cushion layer is made of, for example, high density foam. Other types of materials, such as latex with cotton padding, can also be used to form the protective cushion layer. Preferably, the protective cushion has an upper surface which is coplanar with the support pads in their neutral position. In addition, a surface protective cushion layer can be provided on the surface of the support pads. The thickness of the surface protective cushion is, for example, about 1-2 cm. Other thicknesses can also be useful. A cushion cover 195 is then provided to cover the cushion layer. Continue reading about Comfort cushion or bed...
