Longitudinal adjustment for vehicle seat has two sliding guides near centerline of seat and two small height-adjustable wheels at rear corners of seat to assist in longitudinal motion

摘要

The seat has longitudinal runners which engage longitudinal runners which are hinged to the floor of the vehicle at their front ends. The wheels support the rear of the seat to help it move on the runners. The wheels (21) are mounted on axles (61) which are supported in large-diameter eccentrics (55,57) which are mounted in corresponding holes (35,36) in the vertical triangular sides (33,34) of a support (30). The top flat surface (31) of this support is fastened to the frame of the chair. Rotating the eccentrics by pulling on a cord may alter the height of the wheels, bringing them into contact with the floor of the vehicle.
