Vehicle seat height and inclination control apparatus

摘要

A vehicle seat adjustment apparatus includes a height control device and an inclination control device mounted on a seat frame for independently adjusting the height and inclination of a vehicle seat. A support base slidably supports a seat in a forward and a rearward direction. The seat frame means is mounted on the support base for supporting the seat. A rear portion of the seat is pivotally attached to the seat. A plurality of links pivotally connect the seat frame to the support base for raising and lowering the seat frame relative to the support base to adjust the height of the seat. The plurality of links include a control link, which is rotatably mounted on the seat frame. The height control device is connected to the control link and holds the plurality of links in a selected pivotal position. The height control device is operative to rotate the control link in a first direction to raise the seat and to rotate the control link opposite the first direction to lower the seat. The inclination control device includes a gear rotatably mounted on the seat frame and a member operatively connecting the gear and the forward portion of the seat, such that rotation of the gear pivots the seat about the pivot point along the rear portion of the seat to regulate the inclination of the seat.
