Variable lumbar support assembly

摘要

A variable lumbar support including a frame and a support extending between an upper end and a lower end wherein the support bracket includes a first longitudinal direction. A pad having a first surface is provided within the assembly. The first surface of the pad contacts the lumbar portion of the seat assembly. The pad is positioned between the lumbar portion and the seat back cushion. Upon a sliding movement of the lumbar member along the support while in contact with the pad, a curved surface of the pad is displaced in the first longitudinal direction and a second direction normal to the first direction. As the lumbar member contacts the curved areas of the pad, the foam is displaced and pushed towards (a bulge) the seat back cushion so that the user of the vehicle seat feels a fore-and-aft movement of the lumbar member.
