ABSTRACT:
A bottom adjusting action control system for an adjustable bed is provided that facilitates adjustment of the adjustable bottom sections of the bed via a predetermined path of angular adjustment in reaching final set positions for the back and knee bottom sections. In particular, the control system of the present invention provides a means of adjusting the angular positions of adjustable bottom sections of the bed to predetermined final positions via preset bottom coordinative action patterns carried out by a controller means. The preset bottom coordinative action patterns raise and lower adjustable back and knee bottom sections of the bed in a coordinated manner, so as to adjust the bottom sections of the bed to the chosen angular positions without causing the user to slide relative to the bed, and without exerting uncomfortable abdominal pressure on the user.
