Abstract

Detailed are head rest mechanisms and assemblies containing a flexible collar. Portions of the collar may be moved independently from other portions and may pivot or otherwise move both forward of the seat back and vertically under passenger control. Also described are slide assemblies containing deformable projections for use with vertically-adjustable head rests.

1 . A head rest assembly for a seat back, comprising a collar comprising a central portion and a first member extending therefrom, the first member configured so as to be adjustable both vertically and horizontally relative to the central portion. 
     
     
         2 . A head rest assembly according to  claim 1  in which the collar further comprises a second member extending from the central portion opposite the first member, the second member configured so as to be adjustable both vertically and horizontally relative to the central portion. 
     
     
         3 . A head rest assembly according to  claim 2  in which the first member is configured for adjustment independent of the second member. 
     
     
         4 . A head rest assembly according to  claim 3  in which the first member is configured so as to be adjustable to positions either above or below the central portion. 
     
     
         5 . A head rest assembly according to  claim 4  in which the first member is configured so as to be adjustable to a position forward of the central portion. 
     
     
         6 . A head rest assembly according to  claim 5  in which the first member comprises an elongated rod. 
     
     
         7 . A head rest assembly according to  claim 6  in which the collar is adjustable vertically relative to the seat back. 
     
     
         8 . A head rest assembly according to  claim 1  further comprising a slide. 
     
     
         9 . A head rest assembly according to  claim 8  further comprising a plate to which at least one of the collar or slide is connected.
