| 20110012409 | MECHANISM FOR AN OFFICE CHAIR - A mechanism for an office chair has a displaceable actuating element. The position of the element changes during a movement of the office chair mechanism, and the change in position thereof changes the movement characteristic of the office chair mechanism. The actuating element is operationally connected to a functional element. The position of the functional element changes in the event of a change in the position of the actuating element during a movement of the office chair mechanism. At least one property of the change in position of the actuating element changes in the event of a change in the position of the functional element. | 01-20-2011 |
| 20100295351 | SYNCHRONOUS MECHANISM - The invention relates to a synchronizing mechanism for a correlated seat-backrest movement of an office chair, said mechanism including a base support ( | 11-25-2010 |
| 20100289320 | OFFICE CHAIR OR OFFICE CHAIR COMPONENT WITH AN AERIAL TENSIONING ELEMENT - An office chair or office chair element, such as a backrest or seat, has a flat covering element, such as a fabric, cushioning or webbing element, secured to support elements, such as the arms of a support frame, and tensioned in between. The covering element is provided with a welt strip that, in the fitted state, is placed in an accommodating groove in the support element. The accommodating groove has two oppositely situated contact faces for the welt strip and one of the contact faces is provided with a projection that projects into the accommodating groove and extends in the longitudinal direction of the groove. The welt strip can be pressed into the accommodating groove, resiliently deforming the projection and/or the welt strip and the welt strip, in the fitted state, is positively locked and/or friction-locked in the groove with abutment against the contact faces, with the projection preventing the welt strip from escaping from the accommodating groove. | 11-18-2010 |
| 20090267394 | Mechanism for an Office Chair - A mechanism for an office chair having a backrest support which may be pivoted rearwardly. Adjustment of the backrest pivotal motion is accomplished by the mechanism having a base support which may be positioned on a chair column, a seat support, the backrest support which may be pivoted to the rear, and a pre-tensioned spring arrangement for enabling the mechanism to counter or oppose the movement of the backrest support. The seat support and the base support form a movable unit, which may be moved relative to the chair column depending on the weight of a user applying a load to the seat support. Movement of the movable unit causes an adjustment of the pre-tension of the spring arrangement and/or an adjustment of the spring constant of the spring arrangement. | 10-29-2009 |
| 20090066134 | Permanent Contact Mechanism - A permanent-contact mechanism for an office chair or the like is formed as a comparatively flat permanent-contact mechanism with a seat frame, which can be positioned on a chair upright, with a backrest support, which is arranged on the seat frame such that it can be pivoted about a transverse axis, and with at least one spring-activated or inherently resilient lever element, which interacts with the backrest support such that the backrest support is always pivoted counter to a spring force. The position of the point of rotation of the lever element differs from the position of the transverse axis. | 03-12-2009 |
| 20080272638 | Synchronization Mechanism - 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. | 11-06-2008 |
