Abstract: A coupling unit for connecting a support structure to an elongated side member comprises a body and a recess. The recess is configured to receive a wire member of the support structure. The coupling unit is configured to be connected to the elongated side member by a snap fit. The elongated side member may be part of a frame of a seat.

Abstract: In order to symmetrically act on a support member (20) of a support assembly on both sides using a single Bowden cable (18), a traction cable arrangement is used with comprises the Bowden cable, a first traction wire (17), and a coupling device (16) for coupling the first traction wire (17) to the Bowden cable (18). The first traction wire (17) is fixedly attached to the coupling device (16) and extends therefrom in a first direction. The sheath of the Bowden cable (18) is fixedly attached to the coupling device (16), and the wire of the Bowden cable (18) extends from the coupling device (16) in a second direction substantially opposite to the first direction and forms a second traction wire (19). The first traction wire (17) and the second traction wire (19) are slidably held on the support member (20) and are connected to a seat frame (30) at their ends.

Abstract: A support structure for a seat is provided comprising two lateral side wires (1, 2) and a plurality of transverse wires (4-12) extending between the two lateral side wires (1, 2) is provided. The plurality of transverse wires (4-12) comprises a first transverse wire having a first convolution (4A-12A, 4B-12B) and a second transverse wire having a second convolution (4A-12A, 4B-12B). According to the invention, a shape of said first convolution (4A-12A, 4B-12B) is different from a shape of said second convolution (4A-12A, 4B-12B) for example by varying a dimension like the height of said shapes. With such an arrangement, the transversal resiliency of the support structure may be varied and thus adapted to load bearing requirements.

Abstract: In an adjustable lumbar support device, a wire framework essentially consisting of two lateral side wires (4) and a plurality of transverse wires (8) is connected to a seat frame via a pair of support means (5), each preferably formed of a wire. A first connecting portion (5a) of the support means (5) is pivotably connected to a respective longitudinal side of the seat frame. A second connecting portion (5b) is connected to one of the lateral side wires (4). A third connecting portion (5c) is coupled to the third connecting portion (5c) of the support means (5) located on the opposite longitudinal side of the seat frame by means of an actuating means (10), preferably formed by a Bowden cable. In response to the action of the actuating means (10), the third connecting portions are pulled toward each other, thereby pivoting the support means (5) and moving the wire framework in a direction perpendicular to its plane.

Abstract: A mounting hook for a wire array mountable on a seat frame has a first portion having a seating member running longitudinally along the first portion, a second portion having a channel running across the top of the hook and outboard of the hooking surface, and a hooking member running transversely to the channel and parallel to the seating member. The first, second and third portions define a hooking surface. A method of seat assembly consists of a wire array connecting to mounting hooks by running a mounting wire through the wire seating member of the mounting hook. Such wire is then bent to a transverse angle. After such wire is bent, the mounting hook is slid to the bent area. The bent area is then placed into the channel. The wire array is then ready for mounting on the seat frame through the use of the hooks.
