US 7410219 B2Abstract
Mounting device for a headrest with two headrest rods for a vehicle seat, which includes a first guide sleeve for the height-adjustable accommodation of a first headrest rod, a second guide sleeve for the height-adjustable accommodation of a second headrest rod, and a first receptacle device secured in the backrest, in which the first guide sleeve is held and rests at at least two axially spaced bearing points. A second receptacle device is secured in the backrest, within which the second guide sleeve can be shifted at least in the transverse direction. The second guide sleeve rests in the second receptacle device, which is secured in the backrest. Advantageously, the second guide sleeve is pivotably held in the second receptacle device, which is secured in the backrest, and the second headrest rod is pivotably held in the second guide sleeve.
This application claims priority of German application no. 10 2005 019 946.1, filed Apr. 29, 2005, which is incorporated herein by reference.
The invention relates to a mounting device for the headrest of a vehicle seat. More particularly, the invention relates to a mounting device for the headrest of a vehicle seat headrest with two headrest rods, a first and second guide sleeves for height-adjustably receiving first and second headrest rods, and the first and second guide sleeves being received in the receptacle devices when secured in a vehicle backrest.
To allow the support and height-adjustable mounting of headrests, welded pieces of pipe or openings are customarily mounted in the upper regions of backrests, and are in turn used to affix guide sleeves for height-adjustably receiving the headrest rods of the headrest frame.
An object of the invention is to create a mounting device that, with a simple and cost-effective construction, will compensate for tolerances and dimensional variations, thus ensuring a low level of friction during the height adjustment of the headrest.
According to the invention, both guide sleeves are thus held directly in the receptacle devices in the backrest; i.e., without an adjustable support placed between them. In this manner, a more cost-effective production and simpler assembly can be achieved with fewer components. Nevertheless, deviations in parallelism and dimensional variations in the headrest rods and the receptacle devices secured in the backrest can be compensated for via a suitable adjustment of the second —“movable”—guide sleeve.
According to one preferred embodiment, the second “movable” guide sleeve is mounted in the second receptacle device which is secured in the backrest, at a pivot point or in a pivoting plane, and assumes various pivot positions with differing track widths or dimensional tolerances for the headrest rods or the receptacle devices. Alternatively, however, a rotationally and linearly freely adjustable mounting of the second guide sleeve in its receptacle device is also possible.
FIG. 1 is a partially exploded view of an upper backrest region with receptacles, guide sleeves, and a headrest frame, in a perspective view from the rear;
On a backrest 8, an unillustrated headrest is mounted such that its height can be adjusted, or such that it can be shifted in the vertical Z direction, by way of a headrest frame 7. For this, the headrest frame 7 is adjustably held with its left headrest rod 7 a in a left guide sleeve 1 and with its right headrest rod 7 b in a right guide sleeve 2, as will be described further below.
The guide sleeves 1, 2 are in turn inserted from the top into respective receptacle devices 9, 10 or 13, 14, 15, 16 that are secured in the backrest 8. According to the embodiment shown in FIG. 1, a left receptacle 9 and a right receptacle 10—in the direction of travel X—serve as receptacle devices secured in the backrest, each of which is configured to be tubular with a rectangular cross-section. According to the embodiment of FIG. 2, the receptacle devices secured in the backrest are configured as rectangular openings in a solid structural material, for example horizontal plates, comprising a left upper opening 13 and a left lower opening 14, which may be a rimmed opening, along with a right upper opening 15 and a right lower opening 16, in the backrest 8.
According to the invention the left headrest rod 7 a, as the “fixed” headrest rod, is supported or fixed in the left guide sleeve 1 at at least two bearing points implemented as horizontal (XY) planes, namely an upper bearing point E160 and a lower bearing point E170, and the right headrest rod 7 b is fixed or supported in the right guide sleeve 2 as a “movable” headrest rod at only one bearing point implemented as an XY plane, E190. The three-point bearing created in this manner reduces the degrees of spatial freedom of the headrest frame 7 with the headrest rods 7 a, 7 b to only one degree of freedom, which corresponds to the direction of mounting or adjustment 21 shown in FIG. 3.
In addition to the tolerances in the outer diameters and roundness of the headrest rods, tolerances occur in the Y direction in the track width B between the headrest rods 7 a, b, and in the track width N between the axes A9 and A10 of the openings 13, 14 and 15, 16 secured in the backrest, or the receptacles 9, 10; i.e., tolerances of the backrest 8. If the first receptacle 9 or its axis A9 is used as a reference, these tolerances extend up to the second—i.e. right—receptacle 10 or its axis A10.
With the embodiment of FIGS. 4 a, b, the right headrest rod 7 b is held in the right—movable—guide sleeve 2 such that it can be shifted in the Z direction and is fixed in the XY plane; in this embodiment, the unit that is formed by the headrest rod 7 b and the guide sleeve 2 freely rotatable and/or translatably adjustable in the right openings 15, 16.
FIGS. 4 c, d illustrates an alternative embodiment. In this case, the right “movable” headrest rod 7 b extends through only one bearing point E190 in the movable guide sleeve 2 and can thus be inserted even if it deviates severely from being straight or is curved. For a noise-free and play-free support of the headrest frame 7 in the movable guide sleeve 2, the third bearing point E190 is configured to correspond to the bearing points E160, E170; i.e., according to those of FIGS. 6 a, c. The movable guide sleeve 2 has at its lower end a funnel-shaped widened region 2 b that is apparent in the axial cross-sections of FIGS. 4 c, d and in the radial cross-section of FIG. 7 through the plane E200, and which starts at approximately the third bearing point E190 and leads to a widening of the circumference of the movable guide sleeve 2 toward the bottom. Correspondingly, on the upper side of the movable guide sleeve 2 a funnel-shaped section 2 c that widens toward the top is formed. Thus between the headrest rod 7 b and the inner surface 2 a of the movable guide sleeve 2 gaps form, which give the headrest rod 7 b corresponding freedom of movement, especially for pivoting movements around the bearing point E190.
With this embodiment of FIGS. 4 c, d the right guide sleeve 2 is supported in the lower opening 16 or in the lower region of the receptacle 10, respectively, such that it can pivot around a longitudinal axis A16. Thus the second “movable” guide sleeve functions as a coupling or double joint between the rotational points A16 and E190, respectively, and enables a compensation for different track widths B in the Y direction between the headrest rods 7 a, b and different track widths N between the openings 13, 14 and 15, 16 or the receptacles 9, 10 that are secured in the backrest, without these tolerances resulting in pivoting movements of the headrest rods 7 a, b in the backrest 8. Advantageously, the openings 15, 16 or the right receptacle 10 are configured to have extra space in the Y direction, in order to allow the movement of the movable guide sleeve 2.
The headrest frame 7 further includes tolerances in the parallelism of the headrest rod 7 a, b and the receptacles 9, 10 or openings 13 through 16, respectively, secured in the backrest, in the X direction or the XZ plane. If the first receptacle axis A9 is used as a reference, these tolerances extend up to the second receptacle axis A10, as is shown in the cross-section through the XZ plane in FIG. 5. Staggering of the headrest rods 7 a, b and the receptacle 9, 10 or openings 13 through 16 are compensated for in that the funnel-shaped widened regions 2 b, 2 c—as shown in FIGS. 4 c, d—are also formed in the XZ plane at the upper and lower ends of the movable guide sleeve 2, and provide the necessary pivoting space for pivoting movements around the third bearing point E190. The headrest rod 7 b thus has sufficient pivoting space in the XZ plane to compensate for deviations in parallelism relative to the fixed headrest rod 7 a, without coming in contact with the inner wall 2 a of the movable guide sleeve 2. The inner walls in turn are also advantageously configured to be convex in the XZ plane.
