Publication number: 20100295351Abstract: The invention relates to a synchronizing mechanism for a correlated seat-backrest movement of an office chair, said mechanism including a base support (1) that can be placed on a chair column, a seat support (3) and a backrest support (4). In order to provide a synchronizing mechanism, by means of which a high level of seating comfort can be achieved in an inexpensive manner, a mechanism is proposed where the backrest support (4) is connected to the base support (3) so as to be pivotable about a transverse axis (8) and has an entrainment means (9) that is in operative connection with the seat support (3) in such a manner that when the backrest carries out a pivoting movement (6) backward, the seat support (3) also performs a movement (13) backward.Type: ApplicationFiled: May 13, 2010Publication date: November 25, 2010Applicant: BOCK 1 GMBH & CO.

Publication number: 20100289320Abstract: 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.Type: ApplicationFiled: May 13, 2010Publication date: November 18, 2010Applicant: BOCK 1 GMBH & CO.

Publication number: 20090267394Abstract: 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.Type: ApplicationFiled: April 13, 2009Publication date: October 29, 2009Applicant: Bock 1 GmbH & Co. KGInventor: Hermann Bock

Publication number: 20090066134Abstract: 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.Type: ApplicationFiled: January 12, 2006Publication date: March 12, 2009Applicant: BOCK 1 GMBH & CO.

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.

Publication number: 20080252125Abstract: A device is provided for seat tilt adjustment of a chair, in particular an office chair. To provide seat tilt adjustment, which enables a particularly safe and reliable adjustment of the seat tilt, the device encompasses a base support, a seat support connected to the base support by use of a joint as well as an adjustment mechanism, which allows a selectively forward pivot movement of the seat support beyond a substantially horizontal base position.Type: ApplicationFiled: October 15, 2007Publication date: October 16, 2008Applicant: BOCK 1 GMBH & CO.KGInventor: Hermann Bock

Publication number: 20080136239Abstract: A synchronizing mechanism for a correlated seat/backrest movement of an office chair has a base carrier, which can be placed on a chair column, a seat carrier and a backrest carrier. In order to provide a synchronizing mechanism in which there is no need to adjust a spring force in order to change the “pivoting resistance” of the backrest, the backrest carrier, which can be pivoted about a transverse spindle, is connected on the one hand to the base carrier, via a first link, and on the other hand to the seat carrier, via a second link, such that a pivoting movement of the backrest in the rearward direction induces a raising movement of the rear region of the seat carrier, and that the seat carrier is connected to the base carrier such that a raising movement of the forward region of the seat carrier takes place at the same time. A basic idea of the invention is that the user of the office chair “raises” itself upwards by subjecting the backrest itself to loading.Type: ApplicationFiled: December 26, 2007Publication date: June 12, 2008Applicant: Bock 1 GmbH & Co. KGInventor: Hermann Bock

Publication number: 20080100119Abstract: In order to provide an office chair having a comparatively low constructive effort and expense, a degree of comfort comparable with that of a synchronization mechanism, the chair has a seating element with a seating surface and a back element pivotable around a lateral axis and linked in a jointed manner to the seating element. The seating surface of the seating element is configured in a way that a user performs a movement, which follows the movement of the back element, when the back element is pivoting to a rear position. As a result, a synchronous movement of the body of the user with the movement of the back element is facilitated, without the whole seating element performing the synchronous movement.Type: ApplicationFiled: October 29, 2007Publication date: May 1, 2008Applicant: BOCK 1 GMBH & CO.

Patent number: 6886888Abstract: A synchronizing mechanism for correlated seat/backrest motion of an office chair is provided with a base carrier to be placed on a chair column; a seat carrier, which is pivotable about a transverse axis and, at its front end, articulated to the base carrier; and a backrest carrier, which is also pivotable about a transverse axis and articulated to the base carrier. It is coupled with the seat carrier such that a backward pivoting motion of the backrest induces a lowering motion of the rear end of the seat carrier. The joint between the base carrier and the seat carrier is a turning and sliding joint so that the lowering motion of the seat carrier is combined with a horizontal sliding motion.Type: GrantFiled: May 17, 2002Date of Patent: May 3, 2005Assignee: Bock-1 GmbH & Co.Inventor: Hermann Bock
