A support assembly having a first support region with adjustable degree of support and a second support region with adjustable degree of support, comprising:
- a support member for incorporation into a seat frame,
- a first adjustment arrangement for adjusting the degree of support in the first support region, the first adjustment arrangement comprising a first Bowden cable arrangement,
- a second adjustment arrangement for adjusting the degree of support in the second support region, the second adjustment arrangement comprising a second Bowden cable arrangement, wherein the first Bowden cable arrangement and the second Bowden cable arrangement each comprise a wire guided in a sheath,
- first attachment means for attaching the sheath of the first Bowden cable arrangement to one side of the support member in the first support region,
- second attachment means for attaching the sheath of the first Bowden cable arrangement to the opposite side of the support member in the first support region,
- third attachment means for attaching the sheath of the second Bowden cable arrangement to one side of the support member in the second support region,
- fourth attachment means for attaching the sheath of the second Bowden cable arrangement to the opposite side of the support member in the second support region,
- an actuator coupled to the first adjustment arrangement and to the second adjustment arrangement,
- wherein the actuator is configured to simultaneously act on the first adjustment arrangement and on the second adjustment arrangement in opposite directions,
- wherein a first end portion of the wire of the first Bowden cable arrangement extends from the first attachment means and is adapted to be connected to the seat frame, and
- wherein a first end portion of the wire of the second Bowden cable arrangement extends from the third attachment means and is adapted to be connected to the seat frame.
