Abstract: The invention relates to a thin profile adjustable lumbar support system, particularly for use in automotive seat backs and other equipment used for sitting and reclining. The lumbar support system is assembled utilizing injection molding and overmolding technology to form some components and connect other components.

Abstract: A suspension system for a vehicle seat comprising a support wire having a first end, a second end, and a middle portion between the first and second ends, such that the support wire is folded approximately in half at the middle portion. The suspension system further comprises a coating of overmolded plastic applied to the first and second ends such that the first end second ends are held together by the coating; a bend in the middle portion of the support wire to attach the support wire to a frame of the vehicle seat, wherein the bend is coated with overmolded plastic; a crossbar overmolded on the support wire; an integral attachment clip molded onto the crossbar; and a seat cushion module held adjacent the support wire using the integral attachment clip.

Abstract: A dual cylinder positive displacement pump is used to move drill cuttings. The pump may include one or more of a self-sealing wear ring member/wear plate member interface, stainless steel pumping cylinders, and a hopper with an inclined surface.

Abstract: A method of assembling a dual cylinder positive displacement drill cuttings pump is provided. The method includes providing a hopper including a front end, a generally open rear end with a generally barrel-shaped sidewall extending therebetween to provide a generally barrel-shaped hopper volume, and an inlet port extending through the barrel-shaped sidewall for delivering material into the generally barrel-shaped hopper volume. A rear hopper wall is provided that includes first and second pumping cylinder openings that are spaced apart from each other and at a common elevation from a bottom of the rear hopper wall. An installation configuration for the drill cuttings pump is identified, including a hopper infeed angle. Based upon the identified hopper infeed angle, the hopper is located relative to the rear hopper wall such that an axis of the inlet port of the hopper is positioned substantially at the hopper infeed angle. Then, the hopper is connected to the rear hopper wall.

Abstract: A lumbar support device has a seat frame, a pair of brackets connected to opposite sided of the seat frame, a pair of flexible members connected to the pair of brackets in such a manner as to respectively form a pair of center sections across the seat frame, and an actuator assembly operatively connected to each one of the flexible members. Each one of the flexible members preferably has a pair of levers on opposite sides of the center sections that rotate about the brackets. In operation, the actuator assembly selectively bows the center portions of the flexible members. The actuator assembly preferably includes a reversible gear and a pair of bowden cables that move one pair of levers when the reversible gear is rotated clockwise and move the other pair of levers when the reversible gear is rotated counter-clockwise.

Abstract: A lumbar support device has a seat frame, a pair of brackets connected to the seat frame, a spring assembly connected to the pair of brackets in such a manner as to form a center section traversing the seat frame and a pair of cantilevered ends on opposite sides of the center section, and an actuator assembly operatively connecting the cantilevered ends. The pair of brackets respectively provide a pair of fulcrums about which the cantilevered ends can rotate. In operation, the actuator assembly moves the cantilevered ends of the spring assembly to bow the center portion. The lumbar support device may also have a single cantilevered end.

Abstract: A suspension article has a frame, a substantially uniplaner non-woven grid, and fasteners. The grid is integrally extruded with a pair of attachment strips, and the fasteners attach the grid to the frame through the attachment strips. In the preferred embodiment, the fasteners are a pair of J-strips integrally extruded with the attachment strips. The process for manufacturing the suspension article includes the steps of extruding a grid, extruding attachment strips integral with the grid, stretching the grid between the attachment strips, and attaching the stretched grid to the frame through the attachment strips.
