Abstract:
1. 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 to be incorporated into a seat frame; a first Bowden cable arrangement to adjust the degree of support in the first support region; a second Bowden cable arrangement to adjust the degree of support in the second support region; a first actuator coupled to the first Bowden cable arrangement and to the second Bowden cable arrangement, wherein the first actuator is configured to simultaneously act on the first Bowden cable arrangement in a first direction that increases tension in the first Bowden cable arrangement and on the second Bowden cable arrangement in a second direction that decreases tension in the second Bowden cable arrangement; and a wire-length control mechanism coupled to one of the first Bowden cable arrangement and the second Bowden cable arrangement, wherein the wire-length control mechanism is configured to absorb an excessive length of a wire of the one of the first Bowden cable arrangement and the second Bowden cable arrangement, wherein the wire-length control mechanism comprises a slide member which is slidably coupled to a fixed member, wherein the wire of the one of the first Bowden cable arrangement and the second Bowden cable arrangement is slidably coupled to the slide member, and wherein a sliding movement of the wire with respect to the slide member is limited in one direction by a stop member.
