A seatback of a vehicle seat includes a seatback frame and a backrest attached to the seatback frame. The backrest includes a first supporting area configured to receive a load of a shoulder of the occupant, and a second supporting area configured to receive a load of a spine area of the occupant. Support stiffness in the first supporting area for a vertical load is lower than that in the second supporting area. Support stiffness in the second supporting area for a shearing load is higher than that in the first supporting area.

A seat including an exterior seat surface. The exterior seat surface is movable inward and outward relative to an interior of the seat. A flexible material overlays the exterior seat surface. The flexible material is lockable to restrict movement of the flexible material towards the exterior seat surface. Movement of the exterior seat surface into the seat defines a gap between the exterior seat surface and the flexible material to permit air to circulate between the exterior seat surface and the flexible material to cool an occupant of the seat.

A motorcycle seat assembly that includes a seat pan with a load bearing hammock-type or hammock-style fabric or mesh seat suspension mounted using a suspension mounting bracket to the seat pan that is configured with an integral suspension mounting fixture that enables pre-tensioning of a stretchable webbing of load-bearing fabric or mesh material of the suspension during fixturing and/or mounting of the suspension to the seat pan.

A method of method of manufacturing an upholstered chair for a mass transit vehicle includes forming a seat insert and a backrest insert, injection molding a layer of upholstery having enveloping flanges and beads at a periphery thereof, placing the upholstery onto the seat and backrest inserts such that the flanges and beads engage with an underside of the inserts, and attaching the seat insert and the backrest insert onto a chair frame. The flanges and beads secure the upholstery to the seat and backrest insert.

A seating assembly includes a seatback having a frame and a cushion assembly. A cushion carrier includes a lower member defining a frame receiving cavity. A first set of ribs extend across the frame receiving cavity in a direction perpendicular to a longitudinal extent of the lower member. The first set of ribs extend between the lower member and a lower brace of the frame. A second set of ribs are parallel with the first set of ribs. The second set of ribs are longer than the first set of ribs.

A seat is provided with: a frame (F2); a pad (36) supported by the frame; a skin member (37) covering a front surface of the pad and provided with a first opening (38); an annular plate (46) having a second opening (47) and attached to a part of the skin member surrounding the first opening so that the first opening opposes the second opening; and a garnish (40) including a tubular portion (41) passed into the first opening and the second opening, and retained onto the pad, a flange (42) provided at a front end of the tubular portion and having a larger outer diameter than the tubular portion, and an engagement claw (43) projecting from an outer periphery of the tubular portion, and engaging the annular plate between the flange and the engagement claw.

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.

A mattress arrangement, such as a bed arrangement, is disclosed, comprising an upper mattress and optionally an lower mattress. The mattresses are preferably pocket spring mattresses. A support structure is arranged beneath the upper mattress, and comprises at least one flexible elongate element arranged to extend between two holding elements arranged at opposite sides of at least one variable zone in the bed arrangement. A retraction device is further arranged to control the slack of said flexible elongate element(s) by controlling the length of the flexible elongate element(s) being provided between the holding elements. Hereby, the height and/or firmness of the bed arrangement is controlled in the variable zone(s).

A vehicle seat comprises a seat cushion frame configuring a frame member of a seat cushion, and a seat unit that is supported by the seat cushion frame and on which an occupant sits, that has a higher seating face rigidity in a seat front-rear direction than a seating face rigidity in a seat width direction, and that has the seating face rigidity in the seat width direction set lower at a seat front-rear direction rear side than at a seat front-rear direction front side.

A seat support mechanism including a lifter, and configured to perform a cushion frame suspension function no matter to what height a cushion frame is adjusted. Torsion bars extending in the width direction of a cushion frame and elastically supporting the cushion frame are supported by a link mechanism disposed between sliders and the cushion frame. Even if the attitude of the link mechanism is displaced when the lifter adjusts the height, the positions of the torsion bars are displaced so as to follow the displacement. The torsion bars elastically support the cushion frame no matter to what height the torsion bars are displaced. Thus, no matter to what height the cushion frame is adjusted, the torsion bars are able to support the cushion frame with predetermined elasticity and to exhibit predetermined vibration absorption characteristics.
