Abstract: A seating structure includes a frame, a carrier, and a suspension material. The frame includes first and second side frame members spaced apart in a first direction and defining an opening therebetween. The first and second side frame members have an inner portion facing the opening and an outer portion facing away from the opening, the outer portion including a plurality of first attachment features facing away from the first and second side frame members in the first direction. The carrier includes first and second side carrier members. The first and second side carrier members include a plurality of second attachment features facing the first and second side frame members in the first direction, the plurality of second attachment features engaging the plurality of first attachment features to attach the carrier to the frame. The suspension material is attached to the carrier and extends over the opening in the frame.

Abstract: A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane includes different regions with different stiffness. The membrane may form a part of a seat or a backrest.

Abstract: The invention relates to a chair (1) which comprises a support (6), a seat element (5), a back element (4), a leg element (3), a spring mechanism and a weight-controlled working adjusting element for the spring mechanism.

Abstract: The invention relates to a mechanical assembly (2), said mechanical assembly (2) comprising, in addition to a leaf spring, at least one further spring element, the elastic restoring force of the at least one further spring element and the elastic restoring force of the one or more leaf springs supporting the seat shell (S) with a total restoring force, and/or the mechanical assembly (2) comprising at least two leaf springs and at least two supports, each support being associated with one of the leaf springs, and at least two supports being displaceable beneath the leaf springs by means of an adjustment mechanism and being displaceable on their trajectories by different extents.

Abstract: A chair includes a base, a support element and a torsion element. The support element is coupled to the base and includes a seat region, a backrest region and a transition region connecting the seat region and the backrest region. The backrest region is reclinable relative to the seat region by way of elastic deformation of the support element. The torsion element is coupled to the base and to the backrest region. The torsion element controls the reclining of the backrest region relative to the seat region. The support element is exclusively connected to the torsion element above a lumbar region, wherein the backrest region can be inclined and/or twisted in relation to the seat region.

Abstract: A seating structure includes a frame, a carrier, and a suspension material. The frame includes front, rear, and side portions that define a continuous outer periphery of the frame. The frame further includes a cross portion extending between the side portions. The frame also includes openings in the front and rear portions, with the cross portion between the openings. The cross portion includes stiffening ribs. The carrier includes a suspension material connected to the outer periphery of the frame. The frame and carrier have respective first and second attachment features that engage to lock the carrier onto the frame.

Abstract: A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane has a first region with a first stiffness and a second region with a second stiffness. The second stiffness is greater than the first stiffness. The membrane may form a part of a seat or a backrest.

Abstract: A partition system includes a plurality of wall elements merging one into another, wherein at least one wall element is designed as a stepped element, and wherein at least one wall element is designed as a corner element.

Abstract: A body support structure including a pair of laterally spaced apart supporting arms defining a gap therebetween, wherein each of the supporting arms includes an upper support having an upwardly extending upright and a forwardly extending seat support defining a seat part, and a lower support having an upwardly extending upright spaced apart from the upright of the upper support in a vertical plane. The uprights of the upper and lower supports define a backrest part. A pair of armrests each includes an upwardly extending portion connected to a respective one of the forwardly extending seat supports and a forwardly extending portion pivotally connected to the backrest part. A cross brace extends between and is coupled to the supporting arms proximate the pivotal connection. A flexible membrane extends between and is coupled to the supporting arms.
