Patent number: 10226127Abstract: A resistive motion support mechanism joined to a mounting surface and to a base for providing resistive support to the mounting surface as the mounting surface undergoes one or both of rotational and tilt movement relative to the base, the motion support mechanism comprising: a support bearing connected to the mounting surface and to the base which permits one or both of tilting and rotational motion of the mounting surface relative to the base; a resistance cartridge fixedly connected to the mounting surface such that the resistance cartridge undergoes movement relative to the base and applies a resistive force on the base as the mounting surface undergoes the one or both of rotational and tilt movement.Type: GrantFiled: December 7, 2015Date of Patent: March 12, 2019Assignee: CORECHAIR INCORPORATEDInventors: Patrick N. Harrison, John Foreman

Patent number: 9211013Abstract: A motion support mechanism, for example for a chair, joined to a mounting surface and to a base for providing resistive support to the mounting surface as the mounting surface undergoes one or both of rotational and tilt movement relative to the base. The motion support mechanism includes a support bearing connected to the mounting surface and to the base which permits one or both of tilting and rotational motion of the mounting surface relative to the base, a pivot ball sized fixedly attached to a portion of the base, and, a resistance cartridge fixedly connected to the mounting surface such that the resistance cartridge undergoes movement relative to the base and applies a resistive force on the base as the mounting surface undergoes one or both of rotational and tilt movement.Type: GrantFiled: November 24, 2011Date of Patent: December 15, 2015Assignee: CoreChair Inc.Inventors: Patrick N. Harrison, James R. Edwards, Ken W. Vandervelden, Thomas N. Banks, David R. Gater

Patent number: 5718026Abstract: An adjustable attachment has been developed which can be used in combination with an auxiliary backrest to suspend the backrest from a fixed backrest normally found on a chair or wheelchair. The support structure includes an elongate receiver and a hanger. The receiver extends longitudinally and is normally fixed in a vertical position to the auxiliary backrest and defines a plurality of openings spaced apart along the length of the receiver to form a row of openings. The hanger is shaped to fit in any one of the receiver openings and the receiver has an outer part so that in use the hanger can be engaged through a selected one of the openings. The hanger then extends along the length of the receiver and the outer part can be engaged downwardly over an upper edge of a fixed backrest or other support.Type: GrantFiled: November 12, 1996Date of Patent: February 17, 1998Assignee: Special Health Systems Ltd.Inventors: Patrick N. Harrison, Nenad B. Medjedovic

Patent number: 5524969Abstract: An angularly adjustable backrest mounting assembly for a seat, has an upper transverse member securable at opposite ends to transversely spaced uprights of a seat so as to be angularly movable about a horizontal axis, and a lower transverse member is securable at opposite ends to the transversely spaced uprights below the upper transverse member. An upright member is secured adjacent an upper end thereof to the upper transverse member and adjacent a lower end thereof to the lower transverse member, and a transverse angle retaining member pivotably secured at opposite ends to opposite ends of the upper transverse member is adjustably securable at different heights to the upright member to enable the upper transverse member and the upright member to be retained in the different angular positions. The upright member has attachments to enable a backrest to be secured thereto.Type: GrantFiled: November 8, 1994Date of Patent: June 11, 1996Assignee: Special Health Systems Ltd.Inventors: Patrick N.

Patent number: 5522106Abstract: A seat cushion assembly has a lower layer of resilient shape-retaining material with an upper surface having a pair of adjacent parallel channel-shaped recesses extending rearwardly from a front end of the cushion assembly and shaped to conform to the undersides of the thighs of a sitting person. The upper surface also has a rear recess in a rearward and intermediate area positioned to be beneath the buttocks of the sitting person. An insert of relatively firm deformable material is located in the rear recess of the lower layer, and an upper layer of soft material covers the lower layer and the insert. The upper layer has channel-shaped recesses conforming with the channel-shaped recesses in the lower layer and a buttock-receiving recess over the insert. The insert serving to accommodate ischial tuberosities of the sitting person and prevents the ischial tuberosities from bottoming out through the cushion assembly. The insert also provides an even distribution of forces over these bony areas.Type: GrantFiled: November 18, 1994Date of Patent: June 4, 1996Assignee: Special Health Systems Ltd.Inventors: Patrick N. Harrison, Nenad B. Medjedovic
