Abstract: A cushion article, such as a seat cushion or the like, for snapping in place onto an appropriate seat support without additional attaching means. The seat cushion has a foam body with a snap-ring member molded integral with a peripheral portion of the body, the snap-ring member providing means for snapping the seat cushion over the seat support. A process and a mold assembly are disclosed for molding the seat cushion, utilizing the snap-ring member as an integral part of the process and mold assembly to evacuate entrapped air from the mold cavity.

Abstract: A method of molding cloth. A special multi-layer cloth is first preheated and then drawn into a heated mold by means of a vacuum between the cloth and the mold. The cloth includes a fabric layer having a heat-fixable fiber, a polyurethane foam layer and a polyvinyl chloride film layer bonded together. The cloth is preheated to at least the greater of the set temperatures of the fabric layer and the polyvinyl chloride film. The mold is heated to at least the same temperature. After the cloth has conformed to the contours of the mold, the cloth is transferred to a cooler mold. The steps of heating the cloth in the mold and then cooling the cloth in the cooler mold sets the stitch of the fabric to the contours of the mold. Polyurethane foam may then be poured into the mold and allowed to expand to form a seat cushion or the like.

Abstract: A method of molding cloth. A special multi-layer cloth is drawn into a mold by means of a vacuum between the cloth and the mold. The cloth includes a fabric layer, stitches of the fabric having never been thermally set, a polyurethane foam layer and a polyvinyl chloride film layer bonded together. After the cloth has conformed to the contours of the mold, the shape of the cloth is fixed to maintain the mold contours. To this end, the cloth may be heated, or polyurethane foam may be poured into the mold and allowed to expand.

Abstract: This invention relates to supports, for vehicle seats, having a generally upright configuration. Provision of a plurality of seat adjustments, for operator comfort and safety, performable with an economy of movement and structure which tends to maximize free, usable space within a vehicle cab, is achieved by the invention. A housing member (13) has facing traces (17), and a carriage member (14) bears the seat and a plurality of rollers (51, 53) which engage the traces (17). A bracket assembly (15), disposed between housing and carriage members (13, 14), is selectively slidable with respect to the carriage member (14) to effect height adjustment and, when locked with respect to the carriage member (14), is operable upon to effect weight adjustment.

Abstract: A fore-aft adjustment, for a vehicle seat, employing rollers. The vehicle seat includes a seat assembly coupled to a support assembly. The support assembly includes a first portion affixed to the vehicle and a second portion affixed to the seat assembly. One of said first or second portions includes a plurality of roller structures having rotational axes which are substantially vertical. The other of said first or second portions includes guide members, the roller structures rotatably engaging the guide members to provide for longitudinal movement of the seat assembly with respect to the vehicle.

Abstract: An armrest structure for a vehicle seat. The armrest structure includes a support attached to the side of the vehicle seat, an armrest, and an adjustment structure connecting the support and armrest. The armrest is movable vertically and, in the lowermost travel position, forms an enlargement of the seat portion of the vehicle seat. The armrest is pivotable on the adjustment structure into an upright position.

Abstract: A pair of leaf plate members. A seat support structure includes upper and lower housing members with scissors linkage members extending therebetween, one leaf plate member being attached to the scissors linkage members and the other being attached to the lower housing. The leaf plate members abut at a pivot area. Adjacent the pivot area, portions of the leaf plate members form a weight adjustment control.

Abstract: A vehicle seat having a seat assembly and a height adjuster for altering the displacement of the seat assembly from the vehicle. The vehicle seat includes a support assembly which connects the seat assembly to the vehicle. The support assembly includes a plurality of pivoting members which bear the seat assembly. The height adjuster includes a biasing member which operates the pivoting members to elevate the seat assembly. The height adjuster also includes structure for selectively locking the pivoting members against movement, whereby elevation of the seat assembly is arrested.

Abstract: A vehicle seat having a seat portion for sitting upon and a back portion for resting against. Formed in the seat portion adjacent the juncture of the back and seat portions is a transverse drainage member. A horizontally disposed cross-ventilation member is formed in the back portion adjacent the juncture of the back and seat portions.

Abstract: Vehicle seat assemblies, including seats and their suspensions that are to be mounted to rigid structure of vehicles, have restraint ties completely contained within the assemblies. The ties restrict the amount of upward and forward movement of the seats when they and their occupants are subject to abnormal forces when the vehicles roll over or are involved in other accidents. Each restraint tie is made from strong, flexible material such as wire rope; one end of a tie is connected to one frame of an assembly at the top of its suspension, and the other end is connected to another frame at the bottom of the suspension. The latter frame may be the movable member of a rugged fore-and-aft adjusting mechanism. In addition, pelvic restraint belts are connected to a frame at the top of the suspension.
