Abstract
Abstract An adjustment device for beds, mattresses, seats and the like, which adjustment device includes several support elements extending across an adjustment direction and together spanning a support plane and at least one drive device for pivoting of support elements relative to each other for the purpose of a slope or trend change of the support plane. The support elements are provided with at least one mounting element extending across the support plane. Each mounting element is provided with a pivot joint in its first end region. Spacer devices are provided to maintain the spacing of adjacent mounting elements relative to each other in the region of the pivot joint. Spacing adjusters to change the spacing of adjacent mounting elements are provided on the region of the second ends of the mounting element opposite the pivot joints.
