Abstract
A vehicle seat assembly with a retractable head rest that rotates from an upright use position to a lowered, retracted, stowed position to improve visibility for a vehicle driver. The motion mechanism for the head rest is contained within the body of the head rest itself thus eliminating modification of the seat back to which the head rest is mounted. The head rest is further vertically adjustable relative to the seat back and is rotatably adjustable within a range of upright use positions.
Claims9
A vehicle seat assembly comprising:
- a seat back having an upper end;
- at least one mounting post extending generally upwardly from the upper end of the seat back and being coupled to the seat back;
- a head rest having a three dimensional body defining an interior volume mounted to the post;
- first rotating means within the interior volume of the head rest for rotating the head rest relative to the post about a first axis between a use position and a stowed position;
- and
- second rotating means within the interior volume of the headrest for rotating the head rest relative to the post about a second axis within a range of use positions for the comfort of a seat occupant, wherein the first axis and the second axis are transverse to a normal forward and rearward direction of the seat assembly.

A vehicle seat assembly comprising:
- a seat back having an upper end;
- at least one mounting post coupled to and extending generally upwardly from the upper end of the seat back;
- a bracket supported by the post and movable along a length of the post;
- a head rest having an upper portion and a three dimensional body defining an interior volume mounted to the bracket by a pivot for rotation about a first axis between a use position and a stowed position, the first axis being transverse to a normal forward and rearward direction of the seat assembly, the upper portion of the head rest being displaced in a forward and downward direction in the stowed position relative to the use position to improve rearward visibility;
- first latch means within the head rest interior volume for holding the head rest in one of the use and stowed positions when the first latch means is engaged;
- bias means within the head rest interior volume for urging the head rest primarily in a plane perpendicular to the first axis into the other one of the use and stowed positions when the first latch means is released;
- and
- second latch means for selectively holding the bracket in a position along the post when the second latch means is engaged wherein the position of the head rest relative to the upper end of the seat back is vertically adjusted by moving the bracket along the length of the post.
