A seat bottom assembly including a first frame subassembly and a second frame subassembly supported by and rotatably coupled to the first frame subassembly about a rotation axis, the second frame subassembly configured to rotate about the rotation axis between a first position and a second position. A fabric diaphragm has a fore end connected to the second frame subassembly and an aft end connected to the first frame subassembly. The rotation axis is positioned forward of the connection of the aft end of the fabric diaphragm to the first frame subassembly, such that when the second frame subassembly is in the first position the fabric diaphragm is stretched, and when the second frame subassembly is in the second position the fabric diaphragm is relaxed. In use, the first position may correspond to sitting and the second position may correspond to under seat access.

Backrest for supporting the back of a seated person comprising a rigid backrest frame and a back support structure comprising substantially non-elastic, flexible sheet material. The non-elastic, flexible sheet material comprising a central region and at least four lateral segments, wherein the backrest support surface in its loaded condition has a form-stable, a three-dimensionally curved shape of which a cross-sectional view in the sagittal plane shows a backrest support surface curvature. Preferably, this backrest support surface curvature corresponds with the vertebral curvature at least in a region which corresponding with the lumbar region and a transition region which is formed by a lower part of the thoracic region and an upper part of the lumbar region.

A support assembly for a chair, the support assembly including a carrier shell, a receiving shell mountable on the carrier shell, and a locking element. The carrier shell and the receiving shell each have, in an edge region, connection structures formed in a manner complementary to one another. The connection structures are configured to engage in one another in the mounted state in such a way that they form a through-channel into which the locking element can be introduced.

A chair includes a frame assembly having a first side and a second side opposite each other. The frame assembly includes a first frame, a second frame, a sheet, and a covering member. The first frame has a first opening facing the first side. The second frame includes two opposite fixing portions and a second opening. The second opening faces the second side and overlaps the first opening in position. The sheet includes two opposite first regions, two opposite second regions located between the first regions, and a third region located between the second regions, the second regions are bent under combined pressure of the first frame and the second frame, and the third region is located between the first opening and the second opening. The covering member covers the first frame and the second frame and exposes the first opening, the second opening, and the third region.

A chaise lounge includes a frame, a first sling anchor, a second sling anchor, a sling and a threaded fastener. The frame includes at least two side members. The first sling anchor connects with a first side member and is movable with respect to the frame. The second sling anchor connects with a second side member. The second side member is disposed on an opposite side of the frame from the first side member. The sling is secured to the first sling anchor and the second sling anchor and spans between the first side member and the second side member. The sling defines a support surface on which an associated occupant may selectively reside. The threaded fastener engages the first sling anchor and the first side member. Rotation of the threaded fastener with respect to at least one of the first sling anchor and the first side member results in movement of the first sling anchor with respect to the first side member, which results in movement of the sling with respect to the first side member.

The present disclosure relates to a chair back assembly with an outer frame and an inner frame, wherein the outer frame is manufactured of different material than the inner frame to allow for a variety in support throughout the chair back assembly, resulting in localized support throughout the back of the chair. The availability of localized support results in an improvement in comfort and may also improve production in embodiments utilizing a foam covering. Specifically, the inner frame of the chair back assembly may include at least one vertical member and at least one horizontal member to provide additional support to the user.

The invention relates to a seat arrangement for a means of transport, in particular for a means of passenger transport, wherein the seat arrangement can be arranged on the means of transport by means of a fastening device, wherein the seat arrangement is intended and suitable for providing a sitting position at standing height, wherein the seat arrangement comprises at least one frame element, which is arranged on the fastening device by means of at least one mounting shaft, wherein the at least one mounting shaft is received in at least one receiving device of the fastening device, wherein the at least one receiving device is arranged on a fastening element which is configured as an arm element extending along a height axis.

A seat element includes a carrier frame and supporting surfaces. The carrier frame comprises a left-hand sidepiece and a right-hand sidepiece. The supporting surfaces are configured as the seat surface and back surface. At least one of the supporting surfaces comprises a cover element, wherein the cover element comprises a fabric and is supported on the left-hand sidepiece and on the right-hand sidepiece of the carrier frame. The seat element comprises actuators and the cover element is supported on the left-hand sidepiece and/or on the right-hand sidepiece by means of in each case at least one of the actuator, such that a level of tensioning to which the fabric of the cover element is subjected when the actuator has been activated is greater than a level of tensioning to which the fabric of the cover element is subjected when the actuator has been deactivated.
