Abstract

A vehicle seat ( 1 ) includes a seat part ( 2 ), a vehicle seat base ( 4 ) supporting the seat part ( 2 ), an armrest ( 6 a ), and a first console ( 3 a ) with an operating device ( 10 ). The armrest ( 6 a ) and the first console ( 3 a ) also extend predominantly adjacent to the seat portion ( 2 ) and/or the vehicle seat base ( 4 ). The first console ( 3 a ) is attached to the vehicle seat base ( 4 ) by the first console carrier ( 9 a ) to the vehicle seat base ( 4 ). The armrest ( 6 a ) is fixedly arranged on the first console ( 3 a ) and the first console ( 3 a ) with the armrest ( 6 a ) and the operating device ( 10 ) is connected to the vehicle seat base ( 4 ) via the console carrier ( 9 a ) and can be rotated through an angle of rotation α about an axis of rotation (D) extending in a width direction (Y) in order to simultaneously adjust the position of a point of support (A) for an passenger elbow on the armrest ( 6 a ) and a point of grip (G) for an passenger hand on the operating device ( 10 ) in relation to the seat part ( 2 ) at the same time. The console carrier ( 9 a ) has the axis of rotation (D) in a front region and has at least one lever element ( 13 ) that can be raised in a rear region. Rotation of the first console ( 3 a ) about the axis of rotation (D) can be controlled by raising or lowering the lever element ( 13 ).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to German Patent Application 102024132002.8 filed on Nov. 4, 2024, the contents of which are incorporated by reference herein in their entirety. TECHNICAL FIELD The 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 also extend predominantly next to the seat part and/or the vehicle seat base, and the first console is attached to the vehicle seat base by the first console carrier. BACKGROUND Commercial vehicles, such as agricultural machinery, construction machinery, or transport vehicles, usually have consoles extending next to the seat part, which serve as supports for operating devices such as joysticks or control panels. To prevent the arms of a passenger from becoming tired or tense when holding a joystick or other operating device, armrests are attached to the vehicle seat on which the passenger can rest their arms. Since different passenger are of different heights and have different arm lengths, the height of the armrest must firstly be adjusted so that the elbow rests on the armrest for comfortable operation of the control unit. In a next step, the angle of the armrest must be adjusted so that the passenger can reach the operating device. In a final step, the angle of the control unit relative to the armrest must be adjusted so that the wrist is not overextended. These various adjustment steps are very time-consuming and tedious. In addition, the individual components must offer a wide range of adjustment options. Consequently, the problem to be solved is 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. SUMMARY Therefore, a vehicle seat according to the invention is provided, 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 also extend predominantly next to the seat part and/or the vehicle seat base, and the first console is attached to the vehicle seat base by the first console carrier. The armrest is fixedly arranged on the first console, and the first console is connected to the armrest and the operating device via the console carrier to the vehicle seat base and can be rotated about an axis of rotation extending in a width direction through an angle of rotation α in order to simultaneously adjust the position of a support point for an passenger elbow on the armrest and a grip point for an passenger hand on the operating device in relation to the seat part, wherein the console carrier has the axis of rotation in a front region and has at least one lever element that can be raised in a rear region, wherein rotation of the first console about the axis of rotation can be controlled by raising or lowering the lever element. The longitudinal, width, and height directions describe a Cartesian coordinate system X, Y, Z that is oriented to the main directions of extension of the vehicle seat. Thus, the seat part extends essentially in the longitudinal and width directions, whereas the height direction extends perpendicular to the longitudinal and width directions. Usually, the vehicle seat has a vehicle seat base that is connected to the body of a vehicle. A vehicle seat superstructure is arranged on the vehicle seat base, which usually comprises a seat part, a backrest, and a headrest. The vehicle seat base usually has a spring system that cushions relative movement between the vehicle seat and the body in the height direction and allows the seat part to be adjusted in the height direction. In addition, the vehicle seat superstructure can be moved in the longitudinal direction and the backrest can be rotated in the width direction. Various attachments, such as consoles, are typically arranged on the vehicle seat base. A console is a component that is arranged on the side of the vehicle seat and serves as a carrier structure for various other components. In particular, operating devices such as joysticks, control levers, or buttons are attached to the console, which are used to control the vehicle or attached work equipment or machines. To ensure easy access, the console can usually be adjusted not only in longitudinal direction but also in height direction. Adjustment forwards and backwards serves to adjust the distance between the upper body of a passenger and the console. For smaller passengers, it may be necessary, due to the length of their arms, to move the console and any control unit closer to the upper body, i.e. backwards, in order to be able to use the console and any control unit comfortably. For tall passenger, the opposite may be the case due to longer arms, i.e., it may be necessary to move the console far away from
