Abstract: The invention relates to an adjustment device for vehicle seats, in particular for power driven wheelchairs or rehabilitation vehicles, comprising at least one mounting plate and one bearing plate with a lifting device. In order to allow for an individual adjustment of the seat, the lifting device consists of two to four scissor fittings, which are adjustable in height by driving means. Depending on the height setting of each scissor fitting, a lateral inclination or a tilting forwards or backwards can be achieved in addition to the lifting and lowering.
Abstract: The invention relates to a delordosation device for users of a rehabilitation appliance, in particular for the verticalization of a sit/stand exercise machine or a wheel chair with a seating area and support aids for a user, the seating area supported in a swiveling manner swiveling for verticalization. To avoid hyperlordosis while patients with a restricted mobility are being straightened up in rehabilitation measures or a verticalization in a sit/stand exercise machine 1 or wheel chair, it is provided that the seating area is supported in a swiveling manner, and at least a portion of the seating area is mounted in a movable manner. Thus, a pelvis rotation can be initiated during verticalization, whereby hyperlordosis is avoided.
