Publication number: 20020036422Abstract: An arm assembly (24) is provided for a chair (12). The chair (12) has a forward direction and a rearward direction. The arm assembly (24) includes an armrest (26) and a support structure (28). A mounting device movably mounts the armrest to the support structure. The mounting device constrains the movement of the armrest (26) relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane. The armrest (26) thus move in a substantially planar fashion without changing the orientation of the armrest (26).Type: ApplicationFiled: September 17, 2001Publication date: March 28, 2002Applicant: Formway Furniture LimitedInventors: Jonathan William Prince, Paul Michael Wilkinson

Patent number: 6352307Abstract: A seat, for example, a wheelchair, comprises a seat part, a backrest part, armrests, and footrests. The seat part and the backrest part have a commonly adjustable width, e.g. the side support portions can essentially be inserted into portions of a central frame part, and transversal bars in the backrest have adjustable widths. The seat part also has adjustable front and rear edges, obtained by adjusting adjustable front and rear support portions. The inclination of the backrest is adjusted by clamping screws mounted in side plate portions provided with slots. The height of the backrest can also be adjusted by displacing an upper portion thereof. The inclination of the footrests is varied by moving hinges having a large frictional force normally holding them stationary.Type: GrantFiled: May 13, 1998Date of Patent: March 5, 2002Assignee: Permobil ABInventor: Bo Engman

Patent number: 6302486Abstract: An armrest construction for chairs includes an armrest support having a lower end constructed for attachment to a chair, an upper end, and a mounting block attached to the upper end. A pivot block is pivoted to the mounting block at a main pivot, the pivot block having an upwardly-extending follower. First and second gears are each pivoted to the pivot block, the gears having intermeshing teeth at an inner end such that rotation of the first gear causes the second gear to simultaneously rotate in an opposite direction, the first and second gears further having outer ends. A support plate having pivot/slide members engages the outer ends of the first and second gears, and further has a guide operably engaging the follower to guide lateral movement of the support plate along a predetermined path.Type: GrantFiled: October 2, 2000Date of Patent: October 16, 2001Assignee: Steelcase Development CorporationInventors: Michel A. Lamart, Arnold B. Dammermann, Glenn A. Knoblock, Robert S. Grooters, Larry DeKraker, John Hanna J. Hasbany

Patent number: 6296312Abstract: A multi-position armrest designed for use with a conventional chair to enhance the comfort of an individual seated within the chair. The armrest includes a support arm having a first end adapted for attachment to a chair and a second end coupled to an arm pad in a manner permitting the arm pad to selectively rotate relative to the support arm. The arm pad includes a first circular locking member engaging a second circular locking member on the support arm to selectively lock the arm pad relative to the support arm. The armrest is also provided with a resilient coupling assembly coupling the arm pad to the support arm in a manner permitting the arm pad to move from the support arm to disengage the first circular locking member from the second circular locking member and permit the arm pad to rotate relative to the support arm.Type: GrantFiled: May 29, 1996Date of Patent: October 2, 2001Assignee: Neutral Posture Ergonomics, Inc.Inventors: Jerome J. Congleton, Rebecca Congleton Boenigk, Bobby A. Boenigk, Mark E. Benden

Patent number: 6283551Abstract: An armrest has a cupholder at one end, and is adapted to be pivotally mounted between theater seats that have backrest portions. The armrest with the cupholder is pivotally movable from a generally horizontal position where it can support the arms of a person sitting in the seat, to a generally vertical position where it substantially fills the space between adjacent backrests, and provides a surface that forms a backrest continuation when the arm is pivoted upwardly. The armrest has pads at both the upper and lower surfaces thereof so that it is padded when it is being used as an armrest and also when it is forming a continuation of the backrest of the two adjacent seats.Type: GrantFiled: July 7, 1999Date of Patent: September 4, 2001Assignee: Media Technology Source, Inc.Inventor: Peter W.
