Definitions
- the present invention relates to head rests for seats, and more particularly, to head rests that automatically move upon movement of the seat back.
- Head rests for seats may be adjustable or not adjustable.
- the rest may move up and down, back and forth, or both.
- the invention is a head rest assembly on that is capable of telescoping and tilting, and is also able to assume a default position upon the raising of a seat back from a down or flat position into a deployed position. Specifically, as the seat back is pulled into an up or deployed position, the head rest assembly is extended. Once the seat back is
- the head rest assembly may further be adjusted telescopically up-down, and rotated.
- the seat may be lowered into a down or stowed position. As the seat back travels to the down position, the head rest assembly retracts into the seat.

- Fig. 2 is an elevated view of the present invention attached to a seat frame, and operably connected to a lumbar support;
- Fig. 3 is an elevated view of the present invention as in Figure 2, with the addition of seat padding over the left half of the seat;
- Fig. 4 is a right side view of the invention shown in Fig. 3;
- Fig. 5 is a right side view of the invention shown in Fig. 2 of the present invention;
- Fig. 6 is an enlarged elevated view of a portion of the head rest assembly shown in Fig.2, showing a Bowden cable operably connected to move the assembly;
- Fig. 7 is an enlarged detailed rear view of the top portion of the head rest assembly;
- Fig. 8 is an enlarged top view of the top portion of the head rest assembly;
- ST_LOUIS-27 4 1581-vl-A4 formatted specification for Head Rest for Seat DOC Fig. 9 is an elevated view of the head rest assembly in it fully extended position;
- Fig. 10 is a side view of the embodiment of Fig. 9, as the seat frame is being pulled to an seated position;
- Fig. 11 is a side view of the embodiment of Fig. 9, where the seat frame has achieved its deployed position;
- Fig. 12 is a side view of the embodiment of Fig 10, showing additional seat padding
- Fig. 13 is a top elevated view of the embodiment of Fig. 12, but with a partial cutaway view of the padding around the head rest assembly;
- Fig. 14 is a side elevated view with half of the seat padding cut away;
- Fig. 15 is a further side elevated view with half of the seat padding cut away;
- Fig. 16 is a side view of the head rest assembly of Fig. 15;
- Fig. 17 is side view of the head rest assembly of Fig. 16, without seat padding;
- Fig. 18 is an elevated view of the head rest assembly of the present invention, without the seat frame.
- a seat frame 100 holds both a lumbar support assembly shown generally at 102, and a headrest assembly shown generally at 150.
- the lumbar support assembly 102 may be a movable lumbar suspension assembly as seen in Figs. 1-5, 9-12, and 14-15.
- Headrest assembly 150 is mounted to seat frame 100, as best seen in Figs. 1-6, and 9-17. As seen in all the Figures, but best seen in Figs. 6, 7, and 18, headrest assembly 150 comprises a bracket 151 , a Bowden cable 152, a pair of springs 154, a first
- ST_LOUIS- 2 741581-vl-A4 formatted specification for Head Rest for Seat DOC slide member 156, a second slide member 158, a headrest frame bar 164 and an upper headrest assembly shown generally at 162.
- First and second slide members 156, 158 are attached to C-bracket 160.
- seat 101 begins in an upright position (Fig. 4).
- the seat back is moved to a down position seen in Figs. 12 and 16.
- One end of Bowden cable 152 is attached to a fixed point on the floor or bottom seat frame.
- the other end of Bowden cable 152 has its conduit 153A attached to bracket 151, and its wire 153B attached to first slide member 156. Accordingly, during downward movement, Bowden cable wire is pulled due to the fixed distal connection, resulting in a tension that pulls first slide member 156 towards bracket 151.
- first slide member 156 is moved towards bracket 151
- second slide member 158 which is releasably and slidably connected to first slide member 156, also moves down towards bracket 151.
- springs 154 provide bias for spacing first slide member 156 from bracket 151. Accordingly, the entire headrest assembly 150 is moved into seat 101.
- ST_LOUIS-2741581-vl-A4 formatted specification for Head Rest for Seat DOC limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents.
