Patent number: 7568763Abstract: A seating unit includes a base with a control housing, a back supported on the base for reclining movement, and a seat supported at least partially by a pivoting link on the base for synchronous movement with the back upon recline of the back. A back stop is operably mounted on a pair of parallel guide rods that extend transversely across the control housing for selective movement to a plurality of different positions where the back stop engages the link to limit movement of the seat and hence limit recline of the back to a plurality of selectable recline positions corresponding to the plurality of different positions.Type: GrantFiled: December 2, 2005Date of Patent: August 4, 2009Assignee: Steelcase Inc.Inventors: Adam C. Bedford, David A. Bodnar, Gary Lee Karsten, Robert J. Battey, Kurt R. Heidmann, Gordon J. Peterson

Patent number: 7341313Abstract: An armrest includes an armrest support and a subassembly supported thereon for vertical adjustment by a height adjustment device having a rotatable high-lead-angle threaded shaft, a mating nut, and a trigger. The shaft member is rotatable upon a vertical force being placed on the subassembly, and the trigger engages the shaft to prevent rotation and fix a selected height position. The subassembly includes a housing, an armrest cap, and a pair of swing arms pivoted to each of the housing and cap for adjustably supporting the armrest cap for rotational and translational horizontal movement. Horizontal adjustment is controlled by choice of materials, a frictional wave spring and dampener. Optionally, the armrest cap includes a keyhole slot and one of the links includes a configured protrusion shaped to selectively linearly slide along a long part of the slot . . . or rotate in the circular end of the keyhole slot.Type: GrantFiled: February 24, 2006Date of Patent: March 11, 2008Assignee: Steelcase Development CorporationInventors: Adam C.

Publication number: 20070114827Abstract: A seating unit includes a base, a reclineable back, a seat, and a control operably supporting the back and the seat on the base for movement between upright and recline positions. The control includes a pair of flexible support members and a link that combine to operably support the seat and back for synchronous movement on the base upon recline. The flexible support member is stiff in a vertical direction for carrying a combined weight of the one component and of the seated user, but flexible in a horizontal direction to permit a swinging movement of its ends upon recline. The link is rigid and pivoted to the base for movement about a horizontal axis and also pivoted to the one component. By this arrangement, the flexible member and the link move the one component along a defined path during recline of the back.Type: ApplicationFiled: January 22, 2007Publication date: May 24, 2007Inventors: David Bodnar, Adam Bedford, Kurt Heidmann, Gary Karsten

Patent number: 6932430Abstract: A seating unit includes a base, a seat, a back, and a control operably supporting the seat and the back on the base for movement between upright and recline positions. The control includes a spring providing a biasing supporting force to the back during recline, and further includes a booster mechanism for increasing the supporting force, and still further includes a stop member and a selector device for activating and deactivating the booster mechanism. The selector device is easily movable with a low effort that is independent from friction generated by internal components of the booster mechanism. The stop member is linearly slidably mounted atop a control housing for selectively engaging the booster mechanism and the link for movement between a disengaged position, a booster-engaged position, a partial-recline position, and a recline-prevented position.Type: GrantFiled: March 3, 2004Date of Patent: August 23, 2005Assignee: Steelcase Development CorporationInventors: Adam C. Bedford, Robert J. Battey, David A. Bodnar, Jonathan B. Hadley, Jeffrey A. Hall, Kurt R. Heidmann, Eric Johnson, Gary Lee Karsten, Gordon J. Peterson

Patent number: 6880886Abstract: A seating unit includes a base, a seat, a back, and a control operably supporting the seat and the back on the base for movement between upright and recline positions. The control includes a spring providing a biasing supporting force to the back during recline, and further includes a booster mechanism capable of increasing the supporting force, and still further includes a selector device for activating and deactivating the booster mechanism. The selector device is easily moveable with a low effort that is separated from and independent from any friction generated by internal components of the booster mechanism. In a narrower aspect, the control is powered, such as by an electrical or electromechanical device from a remote location. A back stop is attached to the selector device, for movement between a disengaged position, a partial-recline position, and a recline-prevented position.Type: GrantFiled: June 5, 2003Date of Patent: April 19, 2005Assignee: Steelcase Development CorporationInventors: David A.

Patent number: 6554364Abstract: An armrest structure includes a support and a body rotatably mounted on the support. The support includes a pair of protrusions and the body includes a notched channel for receiving the protrusions. By rotating the body on the support, the protrusions are repositioned in the notched channel between selected stable use positions. The notches are located on both sides of the channel such that the body can be located in a first position with the first surface on the body facing generally upwardly for use, and a second position with the second surface on the body facing generally upwardly for use. By varying the surfaces on the body, and also the engagement of the protrusion with the notched channel, various spacial positions and functional surfaces can be selectively positioned for use.Type: GrantFiled: February 17, 1995Date of Patent: April 29, 2003Assignee: Steelcase Development CorporationInventors: Arnold B. Dammermann, David A. Bodnar, Michael L. Deimen, Thomas R. Hahn, Duane F. Nagel, Charles P. Roossien, David L. Rundhaug, David S. Teppo
