Abstract: An adjustable lumbar support for a seat comprising a pair of parallel lateral rails, wherein each of the lateral rails has a lower end and an upper end, a support panel having a top end and a bottom end, the support panel pivoting at the top end while remaining fixed with respect to the lateral rails, a rail bracket slidably attached to the lateral rails, a spring operatively connected to the rail bracket, wherein the spring biases the rail bracket in a first position, a cable operatively connected to the rail bracket, wherein the cable pulls the bracket from the first position to a second position, and a lift wire pivotably attaching the support panel to the rail bracket.

Abstract: An actuator for manipulating a bowden cable assembly of a lumbar support structure includes a housing having a longitudinal passage and a screw coupled to a cable and operable for moving in the housing passage. A threaded nut is operable for rotating and moving the screw through the housing passage. A barrel is configured for receiving the bowden cable assembly and is operable for providing movement of the cable of a bowden cable assembly completely therethrough and further operable for engaging a sleeve of the bowden cable assembly for preventing movement of the sleeve completely therethrough. The barrel is fixedly coupled to the housing to fix the movement of the bowden cable sleeve with respect to the housing passage such that movement of the screw in the housing is operable for drawing the cable through the fixed sleeve of the bowden cable structure for manipulating a lumbar support structure.

Abstract: A lumbar support mechanism for incorporating in a seat comprises a pair of opposing triangular brackets each having a base and a peak, wherein the brackets are positioned such that said peaks are facing one another. Elongated flexible border elements have ends pivotally coupled proximate the base of each of said brackets. One of the brackets is movable with respect to the other of the brackets to move said peaks together, and the flexible border elements pivot at their ends and flex outwardly away from the brackets to thereby provide support to the lumbar region of a person in the seat.

Abstract: A spring base for upholstered seating, particularly automotive seats having upwardly and outwardly inclined "wings" or bolsters at the sides thereof, consisting of a pair of spaced apart side bolster wires each adapted to be supported by spaced helical springs attached thereto and extending outwardly therefrom for connection at their outer ends to a fixed frame, and a series of relatively closely spaced spring cross wires extending between the bolster wires and connected thereto, certain of the cross wires being of relatively small gauge and extending only between the bolster wires, and certain of the cross wires being relatively heavy gauge and extending beyond the bolster wires and being angled upwardly and outwardly to provide spring support for the bolsters, all with the purpose of providing the necessary spring strength in the various areas of the seat, as well as the necessary closeness of the wires to provide adequate support for the helical springs and adequate support for the cushioning material appl

Abstract: A connector terminus for an elongated member consisting of a pair of spaced apart generally parallel wires, said terminus being formed entirely of the wires themselves and consisting of a loop formed in each of the wires in spaced relation from its end, the loops being coaxial transversely of said member for receiving a retainer pin to complete an actual connection, the extreme end portion of each wire being looped around the side of its standing portion distal from the other wire and extended toward and connected to the other wire to form lever arms resisting any force tending to pull the wires free of the retainer pin.

Abstract: A support grid for upholstered seating of the "bucket" type, consisting of a series of closely space transversely extending spring cross wires defining the main cushion area of either a seat bottom or a seat back, connected at their respective ends to a pair of side spring wires, and angled upwardly and outwardly from the side wires to form the seat "wings" or bolsters, the novelty of the invention lying in the connection of the cross wires to the side wires, in which each cross wire has an S-bend formed therein in a plane normal to the main cushion area, the loop of the S-bend adjoining the main cushion area containing the associated side wire, whereby loading of the associated wing portion tends to open said loop rather than clamping it more tightly about the side wire, so that metal fatigue is reduced, and the other loop of the S-bend opening outwardly, tending to distribute the flexure strains along a longer section of the wire to further reduce metal fatigue, selection of the radius of curvature of this
