Adjustable headrest assembly

Abstract

A headrest assembly for a chair or sofa includes a fixed rear section, and a front section adapted to slide upwardly and forwardly to an inclined orientation with respect to the rear section. Movement of the front section is controlled by a linear actuator, which is connected via a switch to a source of power such as a battery.

1 . A headrest assembly comprising a rear section for mounting in a fixed position on a chair or sofa; a front section pivotally and slidably mounted on said front section for movement between various inclined positions with respect to said rear section; and an actuator for moving said front section with respect to said rear section between the various inclined positions. 
     
     
         2 . The headrest assembly of  claim 1 , wherein said rear section includes a back plate for mounting on the chair or sofa, and a pair of rear end plates extending forwardly from said back plate; and said front plate includes a front wall and a pair of front end walls extending rearwardly from said front wall into overlapping relationship with said rear end plates. 
     
     
         3 . The headrest assembly of  claim 2 , wherein said rear and front sections are generally C-shaped when viewed from above or below. 
     
     
         4 . The headrest assembly of  claim 2 , wherein said rear end plates have an inverted L-shaped configuration. 
     
     
         5 . The headrest assembly of  claim 4  including a vertical slot in a vertical arm of each said rear end plate, an inclined slot in an upper, forwardly inclined arm of each said rear end plate; and a pair of pins extending inwardly from each said end wall of the front section through said slots, whereby the front section can slide vertically while tilting outwardly with respect to said rear section of the assembly. 
     
     
         6 . The headrest assembly of  claim 5 , wherein said linear actuator includes a housing having first and second ends, the first end being pivotally connected to a bottom end of said back plate of the rear section; and a reciprocating shaft extending out of the second end of the housing, the shaft having a free end pivotally connected to a top end of said front wall of the front section, movement of said shaft in said housing causing tilting of the front section with respect to said rear section. 
     
     
         7 . The headrest assembly of  claim 6 , wherein the linear actuator extends between the bottom center of the rear plate and the top center of the front wall.
