Embodiment Construction

[0029] Exemplary embodiments of the present invention will be described with reference to the accompanying drawings. Although some embodiments will be described in the context of a specific field of application, for example in the context of a vehicle seat, the embodiments are not limited to this field of application. The features of various embodiments can be combined with each other, unless otherwise specified.

[0030] Figure 1A and 1B An adjustable seat 10 is shown schematically. in particular, Figure 1A and 1B Various degrees of freedom for adjusting the seat 10 are shown. In the illustrated example, it is assumed that the seat 10 is a vehicle seat, in particular a driver's seat or a passenger seat for a motor vehicle. However, it should be noted that similar configurations may also be used for other types of seats, for example seats for other types of vehicles such as trucks, airplanes or trains, or seating furniture.

[0031] As illustrated, the seat 10 includes ...

Abstract

The invention relates to an adjustment mechanism comprising a plurality of screw shafts (111, 112, 113) and a motor (150) for driving the screw shafts. Additionally, the adjustment mechanism includes a clutch mechanism (160) for selectively engaging the motor (150) with the one or more screw shafts (111, 112, 113). Rotation of the one or more screw shafts (111, 112, 113) caused by the motor (150) translates into adjustment of the seat according to the first degree of freedom. Rotation of one or more other screw shafts (111, 112, 113) caused by the motor (150) translates into adjustment of the seat according to the second degree of freedom.

Description

technical field [0001] The invention relates to an adjustment mechanism for a seat and a seat equipped with such an adjustment mechanism. In particular, the invention relates to an adjustment mechanism for electric multidirectional adjustment of a seat. Background technique [0002] With a view to optimizing the comfort of the seat, it is known to provide the seat with various adjustability. For example, it is known to adjust vehicle seats with respect to the inclination of the backrest of the seat, with respect to the height of the headrest of the seat or with respect to the arched and / or vertical position of the lumbar support of the seat. [0003] To facilitate the adjustment of the seat, it is also known to effect the adjustment of the seat electrically. For example, WO 2017 / 032390A1 describes an electric adjustment mechanism that can be used to adjust various seat components. EP 2 698 278 A1 describes an electric adjustment mechanism for a headrest, which can be used...
