The vehicle seat 10 out 1 is shown as the driver's vehicle seat, however, it is contemplated that the headrest assembly 20 of the present invention can be placed on any vehicle seat within a vehicle, including passenger seats, rear seats, folding seats, and passenger seat options in the third row. Thus, the in 1 shown headrest assembly 20 does not limit the spirit of the invention, as it is based on a front driver side of the vehicle seat 10 will be shown.

As mentioned above, the headrest assembly is 20 an adjustable headrest assembly, wherein the headrest pad 22 is adjustably provided in a forward direction between extended and retracted positions, as indicated by arrow F, and in a vertical direction, as indicated by arrow V, between raised and lowered positions relative to the housing 24 , In the in 1 shown position is the head restraint assembly 20 as being in an initial position H, which is provided with the headrest pad 22 correlated in the lowered vertical position L and the retracted horizontal position R, so that the headrest pad 22 directly in front of the housing 24 is arranged. A movement of the headrest cushion 22 is provided as driven by one or more driven adjustment mechanisms, substantially through the housing 24 are obscured when the head restraint assembly 20 is in the home position H.

With reference to 2A becomes the headrest assembly 20 shown in the starting position H, in which the headrest pad 22 in relation to the housing 24 is in the retracted position R. The headrest assembly 20 is made of a seat back frame 28 worn and is on This is generally fixed in the seat back when assembling 18 ( 1 ) is positioned. The headrest cushion 22 is shown as a two-piece member having a padded front portion 22a for engaging (or adjacent supports) by a user and a rear coupling section 22b having. The housing 24 is also a two-piece component that has a front panel 24a and a rear panel 24b which are used to enclose and cover different adjustment mechanisms and systems used to adjust a position of the headrest cushion 22 be used. As in 2A further shown is an adjustable cover assembly 30 arranged in a stowed position S and adapted to a portion between the headrest pad 22 and the housing 24 to cover, as further described below. The like in 2 B and 2C shown adjustable cover assembly 30 is further exposed while the headrest pad 22 in relation to the housing 24 moves forward in a direction indicated by the arrow F. The adjustable cover assembly 30 is provided as an injection molded multi-part plastic assembly designed to accommodate different headrest assembly adjustment mechanisms and systems 20 to conceal while the headrest pad 22 in relation to the housing 24 adjusted horizontally.

Therefore, the coupling section 22b of the headrest cushion 22 the representation in 2 B after from the front panel 24a of the housing 24 shown spaced so that a distance S is defined therebetween. With the distance S between the coupling section 22b of the headrest cushion 22 and the front panel 24a of the housing 24 it can be seen that the adjustable cover assembly 30 two gap-concealing components, a first component 30a and a second component 30b having in common adjustment components of the headrest assembly 20 cover over the distance S. It is envisaged that the first component 30a in the second component 30b nested or vice versa, so the adjustable cover assembly 30 telescopically in an apparently horizontal manner while the headrest pad 22 from the case 24 in the forward direction, as indicated by arrow F, is moved away. In the in 2 B the embodiment shown is the adjustable cover assembly 30 in a middle position M, wherein the first component 30a partially in the second component 30b the adjustable cover assembly 30 is included. Furthermore, the first component 30a as fully retracted and partially in a nested position in the second component 30b the adjustable cover assembly 30 provided when the headrest pad 22 in the retracted position R ( 2A ) is located. Therefore, the first component 30a and the second component 30b in view of the nested or telescopic relationship of the two components also be referred to as inner and outer component or as gap cover parts.

The adjustable cover assembly 30 is to a chaining system 52 ( 3A ), which serves as a support for the headrest pad 22 which also links to the chaining system 52 is coupled. The engagement between the first component 30a the adjustable cover assembly 30 and the chaining system 52 will be referred to below with reference to 12 further described.

In 2C is the first component 30a the adjustable cover assembly 30 because of the increased distance S between the coupling portion 22b of the headrest cushion 22 and the front panel 24a of the housing 24 shown more clearly. In 2C is the first component 30a in an outwardly extended position relative to the second component 30b so that the first component 30a no more with the second component 30b is nested. Thus, the adjustable cover assembly has 30 in 2C in relation to 2A from a stowed position S thanks to the chaining system 52 moved to an extended position D, which is the headrest pad 22 has moved from the retracted position R in the extended position E. As in 2C shown, represents the head restraint assembly 20 the present invention, a large extension area of the headrest pad 22 in a forward direction F relative to the housing 24 ready, which gives a vehicle occupant more comfort. As in 2C further shown, the adjustment mechanisms of the headrest assembly 20 which allow this horizontal extension, essentially through the adjustable cover assembly 30 and the case 24 obscured while the headrest pad 22 located in the foremost position E. With the hidden adjustment mechanisms, the headrest assembly allows 20 In comparison with adjustable headrest assemblies known in the market, the present invention has a more pleasing aesthetics. Thus, the adjustable cover assembly 30 between stowed and extended positions S, D ( 2A or 2C) depending on the extended position of the linkage system 52 and the headrest cushion 22 operated. It is intended that the headrest pad 22 in relation to the housing 24 about 50 mm from the retracted position R in the extended position E can move forward. Other areas of forward movement are also provided.

The headrest cushion 22 is the illustration according to a support plate 40 coupled, adjustable to a mounting plate 42 is coupled, which in the interpretation in 3A in the case 24 is arranged. The headrest cushion 22 is along the path indicated by arrow V on the basis of a channel and rail arrangement 44 vertically adjustable, between the carrier plate 40 and the mounting plate 42 is arranged. The duct and rail arrangement 44 between the headrest pad 22 and the mounting plate 42 is provided as an arrangement that utilizes multiple channels and multiple rails received therein. As in 3A shown is a channel 46 on a front side 42a the mounting plate 42 to the mounting plate 42 coupled and designed to be a rail 48 sliding into it. The rail 48 is to the carrier plate 40 coupled. It is envisaged that a vertical movement of the headrest pad 22 is to be driven by an adjustment mechanism, which is shown in the form of a linear drive A2.

As in 3A further shown, includes the mounting plate 42 also a back 42b , the outwardly extending brackets 50 having. The brackets 50 are provided as double brackets, which extend from the back 42b the mounting plate 42 extend to the rear, which is most evident in 4C and 4D lets recognize. The brackets 50 serve as a rotating attachment point for the chaining system 52 , Because of the cross-sectional view in 3A is only part of the chaining system 52 shown, however, is provided that the chaining system 52 from the average expert as in 3A shown and in 4A - 4D more clearly shown, as further described below. The linking system 52 can be a four-link chaining system with different sized links. One or more links may have multiple pivot points to provide a multiple link system that operates as an enhanced four-link linkage between front and rear positions. It is envisaged that the chaining system 52 the headrest cushion 22 between an extended position E, as in 2C shown, and a retracted position R, as in 2A and 3A shown, translated. The linking system 52 consists of a plurality of linking members, which are rigid components which are rotatably connected to each other, as further described below.

As in 3A further shown, includes the chaining system 52 a front or first link 54 , which can be described as a driven member, which has an upper portion 56 having, at a pivot point P1 rotatably to a holder 50 a mounting plate 42 is coupled. The first link 54 is provided as one of a pair of front link members, which is based on a transverse element 58 interconnected to form a unitary front linkage assembly. A second or rear link 60 , which can be described as a drive member is in 3A going further than an upper section 62 shown pivotally mounted at a pivot point P2 to a holder 50 the mounting plate 42 is coupled. Just like the first link 54 is the second link 60 as one of a pair of rear links provided by means of a cross member 64 connected to each other. The cross element 64 is in 3A shown in the form of a plate showing the rear links 60 of the chaining system 52 connects to a unified rear link assembly define. Thus, the mounting plate act 42 and the brackets 50 as a coupler for the output member (first link 54 ) and drive member (second link 60 ) in the chaining system 52 , The linking system 52 is designed to control the movement of the headrest cushion 22 from the retracted position R to a series of forward positions arranged along the path, as indicated by the arrow F. The movement of the headrest cushion 22 between extended and retracted position along the path indicated by arrow F is driven by an adjustment mechanism, shown in the form of a linear actuator A1, which is adapted to the chaining system 52 back and forth between front and rear position. The first link 54 and the second link 60 are also rotatably attached to the pivot points P3 and P4 to a base plate 70 coupled. The pivot point P3 is in 4A and 4B shown more clearly. It is envisaged that the base plate 70 , which may be described as a land, in a substantially horizontal manner between the pairs of the first and second links 54 . 60 extends. In 3A becomes a lower section 66 of the second link 60 as at a pivot point P4 to a first side 72 the base plate 70 coupled shown what is in 3C is shown more clearly. As noted above, the first link defines 54 , the second link 60 and the base plate 70 all links of the chaining system 52 which are rotatably coupled to each other rigid components.

As in 3A further shown, the first drive A1 to a holder 80 coupled, further to a lower wall 74 the base plate 70 is coupled. The holder 80 is provided as a connecting bracket which rotatably couples the first drive A1 to a pivot point P5 of the linkage system 52 is driven and at the same time independent of this. The first drive A1 includes a motor 82 that is connected to a spindle or a threaded member 84 is operatively coupled. The thread member 84 is designed by the engine 82 in one by the arrow 86 be driven direction indicated, so that the first drive A1 is a linear drive. A connecting tab 88 is at an upper portion of the threaded member 84 arranged and rotatable with a connecting bracket 68 connected, which at the pivot point P6 of the cross member 64 of the second link 60 extends to the outside. With the headrest pad 22 in the retracted position R, the first drive A1 is designed to be the threaded member 84 using the motor 82 that with the thread 84 is in a threaded engagement, in which by the arrow 86 direction down to the head restraint cushion 22 undress. In this way, the first drive A1 is adapted to the headrest pad 22 as indicated by the arrow F to drive forward by the chaining system 52 is pulled down and forward. While the thread member 84 in one by the arrow 86 driven direction down, pulls the coupling of the connecting flange 88 on the connecting bracket 68 of the second link 60 the second link 60 down to the four-link chaining system 52 in forward and downward directions, as in 3B - 3D further shown. The base plate 70 of the chaining system 52 is provided as a fixed base plate mounted at the pivot points P3 and P4 rotatable with the first and the second link 54 . 60 connected is. In that the upwardly extending connecting bracket 80 provides an independent pivot point P5 for the first drive A1, the first drive A1 has a self-sufficient pivot point in relation to the linking system 52 on. In this way, the first drive A1, as required, to one in relation to the interlinking system 52 independent way, turn, while the chaining system 52 translated back and forth when the position of the headrest cushion 22 is set by a user.

Now, referring to 3B the headrest cushion 22 shown in a forward position F1, which is the in 2 B position F1 shown is similar. Therefore, the distance S is now between the headrest pad 22 and cross element 58 of the first link 54 recognizable. In 3B became the thread 84 through the engine 82 of the first drive A1 in a by the arrow 86 driven downward direction in a position X. That's how the chaining system became 52 by the first drive A1 from the home position H, shown in FIG 3A , driven in a forward position X.
