Coordinative control method for the back and knee bottom sections of a bed or the like

Abstract

A coordinative control method for the back and knee bottom sections of a bed or the like, characterized in that when the back bottom section and the knee bottom section are operated in a coordinative manner, the back bottom section or the knee bottom section is actuated for adaptation to ensure that an action can be carried out based on a preset action pattern starting from the present state of positions.

1 . A coordinative control method for the back and knee bottom sections of a bed or the like, characterized in that when the back bottom section and the knee bottom section are operated in a coordinative manner, the back bottom section or the knee bottom section is actuated for adaptation to ensure that an action can be carried out based on a preset action pattern starting from the present state of positions.  
     
     
         2 . A coordinative control method for the back and knee bottom sections of a bed or the like, characterized in that when the back bottom section and the knee bottom section are operated in a coordinative manner starting from the present state of positions of the bottom of the bed or the like, the knee bottom section is controlled to form the knee lifting angle of the knee bottom section corresponding to the back lifting angle of a preset action pattern, for adaptation to said action pattern.  
     
     
         3  A coordinative control method for the back and knee bottom sections of a bed or the like, characterized in that when the back bottom section and the knee bottom section are operated in a coordinative manner starting from the present state of positions of the bottom of the bed or the like, the back bottom section and the knee bottom section are controlled to aim at the nearest action change point of the knee bottom section on a preset action pattern, in order to let the bottom sections act based on said action pattern.
