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.

Six-way adjuster apparatus and method

A drive mechanism for moving a sunroof panel fore and aft along a pair of laterally spaced apart tracks mounting the sunroof panel includes a drive linkage including a pair of first and second links which are provided adjacent to each track. Each of the pair of links has outboard ends which are connected to the rear end of the sunroof panel and to the roof rearward of the sunroof opening, and inboard ends which are pivoted together to define an apex. A rotatable threaded drive shaft extends longitudinally of the body equidistant between the tracks. A drive bar extends transversely of the roof and has its ends slidably engaging with the apexes of first and second links and has a central portion threadedly engaging with the drive shaft so that drive shaft rotation drives the drive bar fore and aft and the drive bar in turn drives the apexes fore and aft. The apexes travel in an arcuate path during the fore and aft movement and are preferably supported by an arcuately shaped guide tracks which attached to the roof and slidably engaging with the apexes of the drive linkages to define and support the arcuate movement of the apexes during fore and aft movement of the sunroof panel and the drive bar.

The present assembly provides a vehicle seat adjuster apparatus and method for a fore and aft adjustable or reclining vehicle seat. The preferred embodiment adjuster includes a first cam and a second cam in rolling contact with a portion of the seat or a rod to restrain relative movement thereof. Movement in one direction is restrained by the first cam and movement in a second direction, opposite the first, is restrained by the second cam. A handle is provided to release the cams from engagement to allow adjustment of the seat.
