A cushion member 301 is a cushion member made of flexible resin or rubber and used for a passenger seat 300, and includes a porous structural body 1, and a top skin 330 serving as at least a surface FS on a seated person side among surfaces of the passenger seat and integrated with the porous structural body.

A method for producing a seat core material that has a foamed molded substrate and a frame member embedded in a periphery thereof, which includes, as step (a), heating thermoplastic resin expanded beads in a mold cavity, in which the frame member has been disposed, to fusion-bond the expanded beads to each other and to obtain the foamed molded substrate with the frame member being embedded in the periphery thereof; and, as step (b), simultaneously with step (a) or after step (a), forming a void cavity S, S in the foamed molded substrate at a position along and adjacent to the frame member. The void cavity S, S has a size and shape that allows a relative displacement between the frame member and the foamed molded substrate when the foamed molded substrate shrinks after step (b).

According to one or more embodiments, a vehicle seat assembly includes a cushion and a leather trim cover assembly disposed over the cushion. The leather trim cover assembly includes a leather upper layer and a foundation layer secured to the leather upper layer at radio-frequency weld points. The radio-frequency weld points define at least one design boundary adjacent a raised portion of a protruding design in the leather trim cover assembly.

A lumbar support system for a seat backrest, the lumbar support system includes a carrier having a first end and a second end opposite the first end. The carrier is movable with respect to the seat backrest in a first direction and in a second direction opposite the first direction. The lumbar support system further includes a first bladder coupled to the first end of the carrier, a second bladder coupled to the second end of the carrier, and a third bladder coupled to the carrier. The third bladder has a contact surface and is configured to move with the carrier. The first bladder is inflatable to move the carrier in the first direction, and the second bladder is inflatable to move the carrier in the second direction. The third bladder is inflatable such that the contact surface is extendable in a third direction.

A vehicle seat includes a first knitted fabric layer defining an outer surface and a second knitted fabric layer defining an inner surface. The inner surface is opposite the outer surface. The vehicle seat further includes a knitted spacer fabric interconnecting the first knitted fabric layer and the second knitted fabric layer. The knitted spacer fabric resiliently biases the first knitted fabric layer and the second knitted fabric layer away from one another. The knitted spacer fabric is configured to buckle when a seated occupant exerts an occupant load on the vehicle seat. The first knitted fabric layer is more elastic than the second knitted fabric layer to conform to the seated occupant when the seated occupant exerts the occupant load on the vehicle seat.

A vehicle seat assembly includes a seat bottom, a seatback pivotally attached to the seat bottom, and a trim cover disposed over the seatback. The seatback includes a foam cushion positioned on a seatback frame, the foam cushion having at least one plastic component embedded therein. The seatback further includes a rigid support panel embedded in the foam cushion proximate the at least one plastic component. The rigid support panel is positioned to support the trim cover over a void formed in the foam cushion at the at least one plastic component. A method of manufacturing a seatback with a rigid support block is also provided.

Provided is a core material of a seat cushion for a vehicle, including: a thermoplastic resin expanded beads molded article having a substantially rectangular shape in top view, that has thick portions on a front side and both sides of a circumferential portion thereof, and that has an occupant seating portion on an upper surface in an inner region thereof; and an annular frame member that is insert-molded at the circumferential portion of the thermoplastic resin expanded beads molded article. In the thermoplastic resin expanded beads molded article, formed are first slits having: slit pieces that extend along a front frame member at a position in front of the occupant sitting part and inside from the front frame part; and slit pieces that extend along a side frame member at a position outside from the occupant sitting part and inside from a side frame part.

A seat located in a cabin of a motor vehicle includes a seat back and a layer of radiant material embedded in the seat back. The radiant material directs heat to one or more occupants residing in a rear region of the cabin in the motor vehicle.

The present invention provides a soft polyurethane foam molded atticle which has a mounting surface (1A) can be obtained by foaming and molding a raw foaming liquid, and has a constitution which a ratio of a diameter of a foaming cell in the horizontal direction X along the mounting surface (1A) to a diameter of the foaming cell in the vertical direction Y orthogonal to the mounting surface (1A) increases toward the mounting surface (1A) in the vertical direction (Y).

The present invention relates to a suspension arrangement (20, 120) for a seat comprising a plurality of elongate suspension members (21, 22, 121, 122) of a glass fibre filled plastic. Each elongate suspension member (21, 22, 121, 122) of the plurality of elongate suspension members includes in a longitudinal direction thereof a first end (23, 25, 123, 125) and an opposing second end (24, 26, 124, 126). The elongate suspension member (21, 22, 121, 122) has a meandered shape in the longitudinal direction. The present invention relates furthermore to a method for producing an elongate suspension member (21, 22, 121, 122).
