ABSTRACT:
The present invention provides a seat adjuster slide mechanism and method of utilization of the same which is infinitely horizontally adjustable. The seat adjuster slide uses a vertically actuated cam. In its preferred embodiment two opposite surfaces of the cam are utilized and the cam "floats" to equalize the cam angle. Therefore relative movement between the sliding members of the seat adjuster increase the locking force. The present invention also provides a seat adjuster master/slave slide assembly which utilizes one conventional non-infinitely variable type slider mechanism for the master slider in combination with the vertically actuated cam type slave slider adjuster. Use of the vertically actuated cam slider for the slave slider eliminates the prior alignment problem experienced when using a slave adjuster which is non-infinitely variable.
