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 vehicle seat includes a fabric center portion, first and second bolsters, a first seam between the first bolster and the center portion, a second seam between the center portion and the second bolster, and a seat frame. First and second extension members are disposed along and coupled to the respective first and second seams. The first and second extension members are adjustable between first and second positions.

A cushion suspension for a vehicle seat may have a support structure with a substantially tub-shaped profile and at least two lateral portions. Each of the lateral portions may have a flexible suspension portion. A seating surface assembly for a vehicle seat is also disclosed.

A seat back configured to support a back of a seated person includes a back frame constituting an internal framework; and an elastic mat fitted to the back frame so as to cover the back frame from a front side, the elastic mat having a planar shape and being configured to elastically support the back of the seated person. The back frame includes a frame body and a support wire that protrudes forward from the frame body. The elastic mat includes a main support portion configured to support the back of the seated person, and a band portion that extends from a back surface of the main support portion, the band portion being wound around the support wire. The elastic mat has a through-hole through which a head at a distal end of the wound band portion is inserted such that the head is snap-fitted in the through-hole.

A head-pan diaphragm structure attachable to or an integral part of a seat back structure, the head-pan diaphragm structure including high-performance fibers and the head-pan diaphragm structure positionable in a head strike target area of the seat back structure. A seat back assembly including a seat back frame member including spaced portions, a torsion bar attached between the spaced portions, a head-pan diaphragm structure positioned in a framed opening formed by the torsion bar and a portion of the seat back frame member, the head-pan diaphragm structure positioned in a head strike target area, and the head-pan diaphragm member including integrated high-performance fibers.

A foamless seating assembly includes a frame having an inner support member and an outer support member. A first plurality of flexible straps extend about the inner support member of the frame. A second plurality of flexible straps extend about the outer support member of the frame. At least one flexible strap of the second plurality of flexible straps of the outer support member are adjacent to at least one flexible strap of the plurality of flexible straps of the inner support member. A tension assembly is operably coupled with the flexible straps and configured to apply tension to the straps simultaneously.

A mat attachment structure of a seatback includes: a guide wire attached to the mat and provided, at the distal end part, with a straight portion extending in a longitudinal direction of the seatback frame on a tip side of the seatback frame or its root side; and a through-hole formed in the seatback frame and through which the straight portion is insertable. The through-hole is provided with a protruding part which includes a high protruding portion and a low protruding portion formed adjacent to the high protruding portion. In a first movement of the mat, the straight portion moves in a de-insertion direction while coming into contact with the high protruding portion. As the amount of movement of the mat gets larger than the amount of movement of the first movement, a contact position between the straight portion and the protruding part moves toward the low protruding portion.

A hanging type seat mounted in a vehicle comprises a seat main body for supporting an occupant from below; one or more front hanging tools which are passed across a front part of the seat main body, extended upward in the front-back direction, and attached to a structure in the vehicle; one or more rear hanging tools which are passed across a rear part of the seat main body, extended upward in the front-back direction, and attached to a structure in the vehicle; and two or more transverse hanging tools which are passed across both sides of the seat main body, extended laterally upward, and attached to a structure in the vehicle; wherein the seat main body is hung and held by the one or more front hanging tools, the one or more rear hanging tools, and the two or more transverse hanging tools.

A seat for vehicles, in particular motor vehicles, with separate backrest and seat base, includes a seat base and a backrest. The seat base is separate from the backrest, and the seat base is constrained to the backrest so that the backrest base can rotate relative to the seat base. The seat base and backrest are each manufactured as one piece of metallic material in a single cold-molding process. At least one of the seat base and backrest includes an engagement edge configured for engaging, via mechanical interference, with a cover for the seat in order to retain the cover.

Described are passenger support assemblies for a passenger seat, including an expandable inner frame that attaches the passenger support assembly with a seat frame and an expansion mechanism that allows the expandable inner frame to change in width, and an outer frame that includes two side frame elements connected with the expandable inner frame and extending beyond the expandable inner frame, the outer frame configured to change in width in response to a change in width of the expandable inner frame. A diaphragm can held in tension by the two side frame elements of the outer frame to define a seating surface.
