There is provided a cover-material fastening end member including a band-shaped member and a locking member. The locking member is formed such that a width thereof in a direction perpendicular to a surface of the band-shaped member is wider than a width of the band-shaped member. The locking member includes: a center plate-shaped portion, a flange portion, and a plurality of rib portions. The flange portion has a surface extending along a longitudinal direction of the end edge portion of the band-shaped member and perpendicular to a surface of the center plate-shaped portion. The rib portions each has a surface intersecting with the center plate-shaped portion and the flange portion. The rib portions are provided on the center plate-shaped portion along the longitudinal direction of the center plate-shaped portion at predetermined intervals.

A method for manufacturing a backrest and/or having a textile covering or the same, and mounted on a chair tubular chassis or the same includes the following steps: folding the lateral edges of the textile covering and seaming the edges to form lateral sheaths by a lateral seam line, affixing at least three visual markers, (notches), to at least one of the ends of each of the lateral sheaths, a first central notch at the lateral edge of each of the sheaths and two peripheral notches on both sides of the respective central notch, folding the free ends of the sheaths by fitting each central notch between the respective peripheral notches, such that the notches extend facing each other, seaming the free ends of the sheaths at the folding area of the notches by a transverse seam line, and turning over the textile covering by bringing out the corners.

A cover-material fixing clip includes: a chuck having a base portion, a first holding piece and a second holding piece; a hook configured to be engaged with a wire to be located in a groove of a cushion material; and an engagement opening defined between the chuck and a leading end of the hook. The base portion, the first holding piece and the second holding piece define a retention groove for holding the held body attached to the cover material. The engagement opening has an opening dimension in a range from 50% to 80% of a width of the retention groove.

A textile deck assembly, method of fabricating, and method of installing onto a seat frame assembly. The textile deck assembly includes a platform portion and a plurality of straps coupled to a rearward edge of the platform portion. The materials of the textile deck assembly are matched so that the plurality of straps undergoes most or all of the elongation under load (e.g., when a person sits thereon), while the platform portion, even though it is flexible and compliant, is stretch resistant and undergoes little or no stretching under load. A battery of durability tests were performed on the textile deck assembly, including deflection testing, fatigue testing, and drop testing, and compared with conventional seat decks that utilize sinuous springs. The durability of the textile deck assembly to was found to outperform conventional seat decks.

A sheet fastener includes a first fastening member having a long size and a second fastening member having a long size. The first fastening member includes: a first main body portion including a secured surface; a first engagement portion; a plurality of first slit portions formed along an intersecting direction; and a first continuous portion continuous along a longitudinal direction. The second fastening member includes: a second main body portion including a secured surface; a second engagement portion; a plurality of second slit portions formed along an intersecting direction; and a second continuous portion continuous along a longitudinal direction. By using the sheet fastener according to the present invention, the sheet edge portion, which is curved, of the second sheet member can be easily and smoothly fastened with the sheet edge portion, which is curved, of the first sheet member.

A seat or back for a chair comprises a frame having a first edge strut and a second edge strut, the first and second edge struts being on opposite edges of the seat or back. The first edge strut has a groove along all or most of its length, an elongate insert, and a mesh, the mesh being attached to the insert along an edge of the mesh. The insert has a section shaped to correspond to the section of the groove, such that the insert can be urged into the groove, the compression of the groove holding the insert in place.

A cover-material fixing clip includes: a chuck having a base portion, a first holding piece and a second holding piece; a hook configured to be engaged with a wire to be located in a groove of a cushion material; and an engagement opening defined between the chuck and a leading end of the hook. The base portion, the first holding piece and the second holding piece define a retention groove for holding the held body attached to the cover material. The engagement opening has an opening dimension in a range from 50% to 80% of a width of the retention groove.

An apparatus for upholstering a truss allows an operator to staple a fabric web to the truss, rotate the truss, further staple the semi-finished truss and cut the fabric web. The truss is fully upholstered after the end surfaces of the truss are wrapped up in fabric and the fabric stapled in place. The apparatus may accommodate different size trusses. A web of fabric is pulled around at least one roller in the apparatus by rotation of two vise mechanisms on opposite sides of the truss.

A vehicle seat cushion carrier assembly (bottom and back) via which a cushion carrier structure, cushion foam, and upholstery are more easily assembled and installed in a vehicle, optionally as a modular unit. The cushion carrier structure can be multi-piece and incorporate any desired trim units. Strap fasteners are used to secure the upholstery to the cushion carrier structure and cushion foam, creating the desired creating seams, creases, and indentations. Clip fasteners are used to secure the upholstery to the cushion carrier structure around the cushion foam, especially with respect to the seat back. This allows much of the upholstering to be done outside the vehicle, optionally in a modular manner. Finally, these modular features and functionalities allow the cushion carrier assemblies (bottom and back) to be quickly and easily secured to the underlying seat pan and/or seat frame using simple screws, hooks, and clip fasteners.
