Abstract
A headrest for an automotive vehicle seat is disclosed including a headrest frame including a lower portion extending along an upper exterior portion of the seatback and mounted to a mounting frame for generally pivotable forward and rearward movement. A first track provides for the forward and rearward movement and a bladder mounted between the mounted frame and headrest frame selectively expands and contracts to move the headrest frame along the track. The mounting frame is provided with a elongated portion extending into the interior of the seatback and includes a linear gear operated by a reversible motor driven gear for selectively vertically extending and retracting the headrest.
Claims14
A headrest for an automotive vehicle seatback comprising:
- first frame means having a generally hollow interior defining a headrest configuration;
- second frame means in said hollow interior of said first frame means including means for mounting said second frame means to said seatback;
- first track means connecting said first frame means to said second frame means providing for movement of said first frame means relative to said second frame means over a first path of movement defined by said first track means in a generally forward and a generally rearward direction relative to said seatback between a fully rearward position and a fully forward position;
- and
- expansible-contractable means mounted between said first frame means and said second frame means for selectively causing said first frame means to move to any of an infinite number of intermediate positions between said fully rearward position and said fully forward position said first frame means being movable in said forward direction upon expansion of said expansible-contractable means and in said rearward direction upon contraction of said expansible-contractable means.

A headrest for an automotive vehicle seatback comprising:
- a headrest frame having a hollow interior and an elongated lower front portion extending below a top of said seatback along a portion of a front exterior surface of said seatback defining a lower free edge with said headrest mounted to said seatback;
- a mounting frame within said interior of said headrest frame including an elongated portion adapted to be mounted within said seatback;
- first track means connecting said headrest frame and said mounting frame providing for movement of said headrest frame relative to said mounting frame in a generally pivotable forward and rearward direction relative to said seatback about said lower free edge;
- selectively expansible-contractable bladder means mounted between said mounting frame and said headrest frame;
- means biasing said headrest frame against said bladder means;
- and
- second track means on said elongated portion of said mounting frame providing for movement of said mounting frame in a generally upward and downward direction relative of the top of said seatback.

A headrest for an automotive vehicle seatback comprising:
- a headrest frame including an upholstered padded cover, said headrest frame having a lower free edge disposed transversely along an upper front exterior portion of said seatback below the top of said seatback;
- a mounting frame including an elongated portion having a linear gear adapted to engage a reversible motor driven gear;
- an elongated mounting member adapted to be affixed interiorly of said seatback;
- first slidable interlocking tongue and groove means connecting said headrest frame and said mounting frame providing for generally pivotable movement of said headrest frame relative to said mounting frame about said free edge in a substantially forward and rearward direction relative to said seatback;
- selective expansible-contractable bladder means between said headrest frame and said mounting frame for moving said headrest frame in said pivotable forward direction when expanded;
- spring means for biasing said headrest frame in the pivotable rearward direction when said bladder means is contracted;
- and
- second slidable interlocking tongue and groove means connecting said elongated portion of said mounting frame to said stationary mounting member providing for linear movement of said mounting frame generally upwardly and downwardly relative to said seatback dependant upon the direction of rotation of said reversible motor driven gear.

A headrest for an automotive vehicle seatback comprising:
- first frame means having a generally hollow interior defining a headrest configuration;
- second frame means in said hollow interior of said first frame means including means for mounting said second frame means to said seatback;
- first track means connecting said first frame means to said second frame means providing for movement of said first frame means relative to said second frame means over a first path of movement defined by said first track means in a generally forward and a generally rearward direction relative to said seatback between a fully rearward position and a fully forward position;
- said means for mounting said second frame means includes second track means providing for movement of said second track means relative to said seatback over a second path of movement defined by said second track means in a generally upwardly and a generally downwardly direction relative to a top portion of said seatback between a fully up position and fully down position;
- expansible-contractable means mounted between said first frame means and said second frame means for selectively causing said first frame means to move to any of an infinite number intermediate positions between said fully rearward position and said fully forward position said expansible-contractable means includes a bladder assembly mounted to said second frame means including an inflatable bladder acting on said first frame means in said forward direction said first frame means being movable in said forward direction upon expansion of said bladder and in said rearward direction up in contraction of said bladder.
