Embodiment Construction

[0020]Subsequently, embodiments of the invention shall be described in detail with reference to the drawings. In the drawings, like reference numerals designate like structural elements.

[0021]It is to be noted that the embodiments shall not be limiting for the invention, but merely represent illustrative examples.

[0022]FIG. 1 shows an embodiment of an adjustment device 1 adapted to longitudinally adjust the position of a vehicle seat 3 (which is only schematically indicated in FIG. 1) relative to a vehicle floor 4 (which also is only schematically indicated in FIG. 1). By means of the adjustment device 1 the position of the vehicle seat 3 may be adjusted along a longitudinal axis L such that a user may slidably adjust the seating position within the vehicle.

[0023]The adjustment device 1, as generally known, comprises two pairs of guide rails, each pair comprising a first guide rail 10 which is directly or indirectly connected to the vehicle floor 4. A second, upper guide rail 11 is ...

Abstract

An adjustment device for adjusting a longitudinal position of a vehicle seat comprises a first guide rail, a spindle extending along a longitudinal axis, a holding device connecting the spindle to the first guide rail, a second guide rail being linearly movable along the longitudinal axis with respect to the first guide rail, and a gearing fixed to the second guide rail, the gearing being in operative connection with the spindle to move the second guide rail relative to the first guide rail. The holding device herein comprises a body fixed to the first guide rail and made from a plastics material. In this way an adjustment device is provided which may reduce the complexity in particular of the fixation of the spindle to its associated, first guide rail.

Description

TECHNICAL FIELD[0001]The invention relates to an adjustment device for adjusting a longitudinal position of a vehicle seat.BACKGROUND[0002]Within a vehicle the position of a vehicle seat can be adjusted by means of an adjustment device comprising guide rails, an upper guide rail being slidably arranged on a lower guide rail such that the vehicle seat connected to the upper guide rail can be adjusted in its longitudinal position within the vehicle by sliding the upper guide rail along the lower guide rail for example connected to a vehicle floor.[0003]An adjustment device of this kind may for example comprise a spindle fixed to a first of the guide rails and being in operative connection with a gearing fixed to a second of the guide rails. The gearing for example comprises a spindle nut driven by an electric drive device such that by rotating the spindle nut with respect to the spindle the gearing (and together with the gearing the second guide rail) can be moved longitudinally along...
