Description

Vehicle seat with adjustable console Technical Field The present invention relates to a vehicle seat comprising a seat part, a vehicle seat base supporting the seat part, an armrest and a first console with an operating device, wherein the armrest and the first console extend substantially close to the seat part and/or the vehicle seat base and the first console is attached to the vehicle seat base by means of a first console carrier. Background Commercial vehicles, such as farm machinery, construction machinery or transportation vehicles, are often provided with a console extending close to the seat part, serving as a support for a steering device, such as a joystick or a control panel. To avoid fatigue and stiffness of the arms of the occupant when holding the joystick or other steering device, the armrest is attached to the vehicle seat and the occupant can rest the arms on the armrest. Since different passengers have different heights and different arm lengths, the armrest height first needs to be adjusted so that the elbow is placed on the armrest to operate the control unit comfortably. Then, the angle of the armrest needs to be adjusted so that the passenger can reach the operating device. Finally, the angle of the control unit relative to the armrest must be adjusted so that the wrist does not overstretch. These laborious conditioning steps are time-consuming and time-consuming. In addition, each component needs to have a wide adjustment range. The problem to be solved is therefore to provide a vehicle seat in which an improved adjustment system simplifies the adjustment of the console and reduces the manufacturing costs and assembly effort of the vehicle seat. Disclosure of Invention Thus, according to the present invention there is provided a vehicle seat comprising a seat component, a vehicle seat base supporting the seat component, an armrest and a first console with an operating device, wherein the armrest and the first console extend substantially proximate the seat component and/or the vehicle seat base, the first console being attached to the vehicle seat base by a first console carrier. The armrest is fixedly arranged on a first console, which is connected to the armrest and the operating device and to the vehicle seat base via a console carrier and which can be rotated by a rotation angle α about a rotation axis extending in the width direction in order to simultaneously adjust the position of a support point for the elbow of the passenger on the armrest and a holding point for the hand of the passenger on the operating device relative to the seat part, wherein the console carrier is provided with a rotation axis in the front region and with at least one lever element which can be lifted in the rear region, wherein the rotation of the first console about the rotation axis can be controlled by lifting or lowering the lever element. The longitudinal direction, the width direction and the height direction describe a cartesian coordinate system X, Y, Z which is oriented along the main extension direction of the vehicle seat. Thus, the seat part essentially extends in the longitudinal direction and in the width direction, while the height direction extends perpendicular to the longitudinal direction and the width direction. Typically, a vehicle seat includes a vehicle seat base that is coupled to a vehicle body. A vehicle seat superstructure is mounted on a vehicle seat base, the vehicle seat superstructure generally comprising a seat part, a backrest and a headrest. The vehicle seat base is typically provided with a spring system that dampens relative movement between the vehicle seat and the vehicle body in a vertical direction and allows adjustment of the seat components in a height direction. Further, the vehicle seat upper structure is movable in the longitudinal direction, and the backrest is rotatable in the width direction. Various types of accessories, such as consoles, are typically mounted on a vehicle seat base. The console is a component provided on one side of the vehicle seat, and serves as a bracket structure for various other components. In particular, an operating device such as a joystick, a control lever or a button is attached to the console for controlling the vehicle or the connected equipment or machine. To ensure easy access, the console is generally adjustable not only in the longitudinal direction but also in the height direction. The forward and rearward adjustments are used to adjust the distance between the passenger upper body and the console. For smaller occupants, it may be necessary to move the console and any control unit close to the upper body, i.e. backward, due to arm length limitations, in order to be able to comfortably use the console and any control unit. For a tall occupant, the situation may be reversed due to the longer arm, i.e. the console may need to be moved away from the upper body, i.e. forward. The operating device, in particular the joystick
