ABSTRACT:
An automobile seat height adjuster includes a linkage base frame between the seat's side frames and seat brackets so as to be vertically swingable. The base frame has two pairs of linkage members interconnected by respective shafts. Each of the linkage members extends between one of the side frames and one of the brackets so as to be collapsable. A power transmission mechanism transmits to the linkage base frame power generated by operation of an operating knob and causes the linkage base frame to swing vertically, thereby causing the seat to move vertically. Stops on the linkage base frame abut the installation surfaces, limiting downward movement of the seat and keeping the seat in a lowermost position at which side frames of the seat are spaced from the installation surfaces.
