Publication number: 20090174251Abstract: A seating unit that includes a linkage mechanism adapted to move the seating unit between extended and reclined positions, and a chassis is provided. The linkage mechanism includes a seat-mounting link, a base plate fixedly mounted to the chassis, a back-mounting bracket rotatably coupled to the seat-mounting link, a back drive link in generally laterally-spaced relation to the seat-mounting link, and a front-lift assembly that is rotatably coupled to the seat-mounting link. In operation, a rearward occupant force on the back-mounting bracket generates a rearward bias that is converted to a laterally-directed force through the back drive link to the front-lift assembly. Upon receiving this force, the front-lift assembly translates the seat-mounting link forward and upward in relation to the base plate, such that, the seat-mounting link is consistently biased in a particular inclination angle with respect to the base plate throughout adjustment.Type: ApplicationFiled: January 2, 2008Publication date: July 9, 2009Applicant: L & P PROPERTY MANAGEMENT COMPANYInventors: Gregory Mark Lawson, Robert Dean Donovan

Patent number: 7481494Abstract: A wheelchair includes a seat and a back that are pivotally supported in two side members and are kinematically interconnected in such manner that an angle between the seat and the back will increase when the back is swivelled backwards about its pivotal support in the side members, which kinematic connection comprises a link connection between the seat and the back. The link connection is in the form of a link arm arranged under the respective pivot supports of the seat and the back so that the distance between the back pivot support and the back link arm connection is less than the distance between the seat pivot support and the seat link arm connection, and that the axis of rotation of the seat through the seat's pivot support in the side members passes essentially through or close to the user's center of gravity.Type: GrantFiled: September 8, 2003Date of Patent: January 27, 2009Assignee: Handicare Produksjon ASInventor: Morten Sagstuen

Publication number: 20080272638Abstract: A synchronization mechanism for a correlated movement of a seat and a backrest of an office chair contains a basic support placeable on a chair post, a seat support and a backrest support. To provide a synchronization mechanism for which an adjustment of a spring tension to change the “tilting resistance” of the backrest is not required, a mechanism is proposed whereby the backrest support that is pivotable around a swivel axis is directly linked in a pivotable manner to the basic support, and to the rear end section of the seat support, such that a backward tilt of the backrest induces a lifting of the rear area of the seat support. The seat support is so linked to the basic support as to cause a lifting of the front area of the seat support when the user of the office chair “lifts” him/herself up by leaning against the backrest.Type: ApplicationFiled: October 29, 2007Publication date: November 6, 2008Applicant: BOCK 1 GMBH & CO.

Patent number: 7441839Abstract: A chair includes a supporting frame and a seat portion which is foldable about a transverse fold to define a rearward portion behind the transverse fold and a forward portion, forward of the transverse fold. The seat portion is supported above the supporting frame by its rearward portion. The chair also includes a reclinable back portion and a recline mechanism with which the back portion is connected for reclining action of the back portion. The recline mechanism is operably linked to the rearward portion of the seat portion such that on reclining action of the back portion, the rearward portion is moved to increase in rearward tilt angle and to obtain a net increase in height above the supporting frame, with a consequent folding of the seat portion about the transverse fold line under the weight of the occupant.Type: GrantFiled: March 28, 2006Date of Patent: October 28, 2008Assignee: Formway Furniture LimitedInventors: Mark Rundle Pennington, Jon Leonard Fifield, Robert Bruce Stewart

Patent number: 7401858Abstract: A system and method are presented for discovering mobile collaborators on a peer-to-peer (P2P) network. Each collaborator is identified on the P2P network by a unique ID. Each collaborator may also be identified by an identity file posted on the P2P network. Collaboration applications may include any of a variety of applications involving the exchange of information between 2 or more collaborators, such as voice over IP (VoIP). Dynamic file querying can be performed to filter the identity files most relevant to a particular peer partner. Web services are used end-to-end between P2P mobile devices and also between devices and third party service providers. Search engines use self-provisioning concepts for searches and WEB services querying. End-user devices register their personal information on P2P networks using identity self-provisioning and WEB services templates for a variety of uses, such as personal, gaming or business.Type: GrantFiled: May 20, 2004Date of Patent: July 22, 2008Assignee: Manplus Co., Ltd.Inventor: Jong-Ho Lee
