ABSTRACT:
A manually operable four-way automotive seat adjustment assembly is disclosed. The assembly includes a fore and aft adjustment mechanism together with a vertical adjustment mechanism that enables the seat frame member to pivot up and down relative to the carriage/base subassembly. A combination quadrant/lift link is pivotably mounted to the seat frame member and has a support pin fixedly attached thereto at a point radially spaced from the pivot point of the quadrant. The support pin is journalled to a mounting bracket that is slidably mounted to the carriage member so that the bracket can take up the fore and aft movement of the support pin as the quadrant rotates with the raising and lowering of the seat frame. The mounting bracket is preferably made of a hard plastic material to reduce noise and provide ease of operation.
