Abstract:
A seat assembly (104) for task-oriented seating comprises a seat support (222) and a seat (108) coupled to the seat support (222). The seat (108) is movable under load, such as from the user's weight and movements, relative to the seat support (222). The seat (108) has a cushion (242) molded over a supporting armature (240) with multiple bias elements. The seat (108) and seat support (222) are configured to deflect by predetermined amounts at defined locations over an extent of the seat assembly (104). In this way, the seat assembly (104) provides for a range of comfortable and effective positions for users engaged in different active motions and having different preferences and sizes.
Abstract:
A seat incorporating insert(s) intermediate its upper and lower surfaces. A seat insert for the support of the users buttocks conforms to the user's body, has "rebound7' properties, and areas adapted to underlie the perineum and/or ischiums of a user softer than the rest of the seat insert. Alternatively, a perineal insert and/or ischium inserts may be used without the seat insert described. Finally, a heatable insert can be used in conjunction with or in the absence of said seat inserts to provide heat for the comfort of a seat user. In all cases, the aforesaid inserts are preferably completely encapsulated and enclosed by the foam materials making up the seat, which can be accomplished by molding the seat around the insert(s), creating a seat with various internal density zones, adjustable heat, and enhanced abilities to conform to the user's body, while limiting pressure on perineum and/or ischiums.

Abstract:
Sitz- und Lehnpolster (11,12) aus Schaumstoff, in das Versteifungskörper (131, 132, 133, 134) aus Schaumstoff höherer Eindruckhärte und geringerer Dichte eingeschäumt sind. Die Versteifungskörper sind Platten (133) oder Prismen (131, 132,134), die quer zur Sitzrichtung liegen, oder an den Enden U-förmig gebogene Platten. Die Versteifungskörper sind aus geschlossenporigem Polyurethanschaum oder offenporigem Meiaminschaum; der umgebende Schaumstoff ist offenporiger Polyurethanschaum.
Abstract:
There is provided a vehicle seat core member that is superior in terms of a dimensional accuracy as well as integrity of a thermoplastic resin expanded beads molded body and a frame member. A vehicle seat core member (100) is formed as an integrally molded article of a thermoplastic resin expanded beads molded body (10) and a frame member (20), the thermoplastic resin expanded beads molded body (10) is formed of thermoplastic resin expanded beads (30) having through holes (32), and a porosity of the thermoplastic resin expanded beads molded body (10) is 10 vol% or more and 40 vol% or less.

Abstract:
A pressure control layer (1) for use in a mattress or in a cushion for a seat. The layer (1) includes a plurality of interconnected fabric pockets (11) each enclosing at least one spring member (13). The fabric pockets (11) are made from elastic material. The pressure control layer (1) also has upper and lower fabric sheath portions (5,7), and each fabric pocket (11) has at least one elongate seam (9) formed between the upper and lower fabric sheath portions (5,7), these elongate seams (9) interconnecting and defining the periphery of the fabric pockets (11).
