Abstract: A lumbar support assembly (2) comprises a support arrangement (3) which may have the form of a wire framework with two side wires (4) and a plurality of transverse wires (6). A Bowden cable arrangement (10) with a single Bowden cable is attached by two plate clips (15, 17) to the two side wires (4). A first end portion (13) of the wire (12) of the Bowden cable arrangement (10) is anchored to a front edge of a seat frame (1), while a second end portion (14) of the wire (12) is coupled to an actuator (20) for adjusting the tension of the Bowden cable. The lumbar support assembly (2) thus requires only one single Bowden cable to arch the lumbar support assembly at least in a lumbar region and to adjust the degree of lumbar support accordingly.

Furthermore, an adjusting mechanism comprising the coupling unit with which a support structure may be adjusted in a seat frame is provided.

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: Lumbar support for a seat backrest, comprising a support basket (10) extending in the longitudinal direction of the seat backrest, a frame (12) to which the support basket (10) is mounted and an adjustment device (11) which changes the position of the support basket relative to the frame, the adjustment device including a plurality of adjustment members (60) some of which are movable with respect to one another.

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: 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: In a seat with a table function, an upper portion of the backrest can be pivoted forward so as to bring a back surface of the backrest into a horizontal position so that it can be used as a table. A support structure (2) in the form of an articulated suspension is provided which provides support for upholstery of the seat and at the same time also gives the necessary freedom to the backrest to be pivoted forward. The support structure (2) comprises a first portion (2a) and a second portion (2b) which are connected so as to be pivotable with respect to each other. Both the first portion (2a) and the second portion (2b) are essentially formed of a wire framework consisting of a pair of lateral side wires (4a, 4b) and transverse wires (8a, 8b) extending between the lateral side wires (4a, 4b).

Abstract: A seat suspension arrangement intended to provide greater protection for occupants of a vehicle seat in the event of a rearward collision in a motor vehicle, comprises a platform element intended to be supported in the frame of the back rest of a vehicle seat in order to provide support for the seat upholstery, the platform element comprising side rails (1) between which are coupled sinuous wire springs (3) and a plurality of link means (6, 300, 301, 302) by means of which the platform element may be suspended in the frame of a vehicle seat. At least some of the link means (300, 301, 302) are designed to collapse under abnormal load such as would occur in a vehicle collision from the rear, to allow the platform element to move relatively to the seat frame and thus to provide protection for the seat occupant against rearward impact.
