- FIG. 1 shows a headrest according to the main claim in a ground state
- Figure 2 shows the headrest according to the main claim in a comfort state
- Figure 3 shows a method that equips the headrest in the context of the present invention with a Bowden cable.
- FIG. 1 shows a headrest 1 according to the invention in a basic state
- Such a headrest 1 is usually mounted on the backrest of a vehicle seat. But it is also conceivable that the headrest 1 is attached to the body of a vehicle.
- the headrest 1 comprises a first component 2 and a second component 3, wherein both are provided so that the first component 2 is movable relative to the second component 3.
- the first component 2 is movable relative to the second component 3.
- the second component 3 has an opening in which the first component 2 can be arranged.
- the opening is formed so that the first component 2 arranged therein is guided by the walls of the opening during its movement. As a result, the direction of movement of the first component 2 relative to the second component 3 is determined.
- the first component 2 is in the position in which it is usually farthest from the head of a seat occupant.
- a Bowden cable is provided on the headrest, which consists of a shell 4 and a core 5.
- the core 5 is sheathed by the sheath 4, can be moved relative to the sheath 4, and a part of the core protrudes from the sheath 5.
- the core 5 is connected to the first component 2 in such a way that the core carries or transports the component when the part of the core projecting out of the sleeve is reduced in size.
- the core 4 at its end a barrel 9, which is arranged in a provided for them on the first component 2 notch 10. Only in an accident situation, especially in a rear impact, which is from the shell. 4
- the headrest 1 in the illustrated embodiment also includes a locking means 7 which can be moved along a locking direction, wherein in the illustrated embodiment, the locking direction is substantially preferably perpendicular to the direction along which the first component is moved.
- the locking means 7 acts with a shape and
- Frictional means 6 in the present embodiment has a sawtooth pattern.
- the locking means 7 In a locking position, the locking means 7 is arranged between two teeth of the sawtooth pattern.
- the sawtooth pattern is so pronounced that one side of the single sawtooth prevents the first component 2 from being moved away from the head of the seat occupant.
- the other side of the sawtooth has a slope through which a power contribution can be transmitted to the locking means 7 when the first component 2 is moved in the direction of the head of the seat occupant.
- the locking means 7 can be moved to a non-locking position, which releases the movement of the first component to the head of the seat occupant, at least for a short time.
- the locking means 7 for example, biased by a spring means in the direction of its locking position.
- the headrest further comprises an actuating means with which the locking means 7 can be transferred to the non-locking position, whereby the adjustment of the comfort position is made possible by the first component 2 is displaced relative to the second component 3 from the head of the seat occupant.
- FIG. 2 shows the headrest 1 according to the invention from FIG. 1 in a comfort state from different perspectives and as a cross section.

- This can for example be effected by a spring (not shown), which in the
- Actuating means is arranged and ensures in the use situation that the length L of the part of the soul, which protrudes from the shell 5, remains substantially unchanged. But even by self-locking or friction between soul and shell, it is possible that the length L remains unchanged regardless of the respective comfort position.
- the soul therefore forms a loop 4, wherein the measure of the soul 4, which protrudes from the shell 4, remains unchanged with each change in the comfort position. Only in the event of an accident, the soul is jerked by an actuator and any loop is stretched at least partially. Once this is done, the core 5 pulls the first component 2 towards the head of the seat occupant so that the distance between the first component and the head of the seat occupant is reduced.
- the soul stands out again by the desired amount L from the sleeve. Since the first component is only moved when the soul is braced, the forces for tensioning the soul are very low and are therefore very fast, so that very short response times of the headrest according to the invention are guaranteed in a rear impact.
- FIG. 3 shows a method for mounting the Bowden cable on the headrest, the individual method steps being illustrated in the subfigures (a) to (e).
- the Bowden cable consists of a shell 4 and a soul 5.
- This connecting means is preferably a clip or latching connection.
- the barrel 9 is anchored at the end of the core 5 in a recess 10, in particular clipped or latched (see Fig. 3b).
