Problems solved by technology

[0005] This arrangement has a number of substantial disadvantages: firstly, the drive unit is relatively close to the seat occupant's head, so that for the driver the noise generated by the operation of the drive device is annoying
For this purpose, it is best to equip an adjustment mechanism by means of which the shape of the seat back can be changed in this area, which also requires space

Embodiment Construction

[0035]figure 1 A first embodiment of the regulator according to the invention is shown.

[0036] In the adjuster according to the present invention, a guide rail 5 is provided on a plate 19 indicated by a dashed line, and an adjusting element 4 can move up and down along it. A headrest comprising a cushion 1 and two supports 2 can be inserted into the seat back 3 and in this case engaged with the adjustment element, that is, the movement of the adjustment element also makes the headrest as indicated by arrow A Move up and down like that. The adjustment element 4 is a part of the headrest support module 20, and the headrest can be engaged with the headrest support module 20 or the headrest can be inserted therein.

[0037] In addition, a drive unit 8 is provided, which can basically be installed in any suitable position in the seat, preferably at a distance from the head of the user. An operating unit 9 is connected to the drive unit 8, by means of which the user can select an adj...

Abstract

An adjuster device for height adjustment of a headrest (1, 2) on a seat (3) is disclosed, comprising a head support, provided with adjuster means (4) which may move in an adjustment direction (A), embodied such as to be able to engage with a headrest (1, 2) which may be inserted in the headrest housing, whereby drive means for generating an adjustment movement for the adjuster means (4) are further provided. The drive means (4) thus form a physically-separate unit from the headrest housing. The transmission of the adjustment movement of the drive means (8) to the adjuster means (4) is carried out by means of a flexible transmission means (16), such as, for example, a flexible shaft or a bowden cable. The drive unit (8) can thus be positioned independently of the headrest housing.

Description

Technical field [0001] The present invention relates to an adjuster for vertically adjusting a headrest, such as a headrest of a seat in a motor vehicle. Background technique [0002] The seat in a motor vehicle is provided with a height-adjustable headrest, so that the height of the headrest can be adapted to the length of each seat user, such as a driver. To make the vertical adjustment easier, the prior art uses a regulator with an electric drive. Such an adjuster also provides the advantage, for example, that the height of the headrest can be automatically adjusted according to the stored data of each driver. [0003] in Picture 9 In, schematically shows this kind of traditional electric regulator. A headrest including a cushion 1 and a support rod or support bar 2 is engaged in the seat back 3 of a seat in this case. In this case, the support rod 2 is engaged with the adjustment element 4 of a headrest support module 20, wherein the adjustment element 4 can move in the vert...
