Abstract
Abstract A preferred embodiment seat adjuster according to the present invention has a first link which is pivotally connected typically along its rearward end to the vehicle floor. A powered gear is connected to the first link and is meshed with a sector gear which is connected to the forward end of the vehicle seat adjuster. The sector gear is also connected to the vehicle floor. Slidably mounted to the first link is a second link having a sector gear connected to its rearward end. The vehicle seat (or frame) is pivotally connected along its forward end to the second link and the vehicle seat has a powered gear which in meshed with the rearward sector gear of the second link. Longitudinal movement of the seat is provided by a worm gear rotatably connected to the second link and meshed with a rack connected with the first link. Elevation of forward end of the vehicle is accomplished by the powered gear rotatably connected with the first link and meshed with the sector gear connected with the vehicle floor. Elevation of the rearward end of the vehicle seat is accomplished by the powered gear connected with the seat which is meshed with the sector gear which is connected to the rearward end of the second link.
