Description

Vehicle seat with adjustable console Technical Field The invention relates to a vehicle seat comprising a seat part that can be moved back and forth in a longitudinal direction and comprising a first console that can be moved back and forth in the longitudinal direction and a vehicle seat base, wherein the vehicle seat base is provided with at least one adjustment rail and a first slide attached to the adjustment rail, wherein the first slide can be moved back and forth in the longitudinal direction by means of the at least one adjustment rail. Background Commercial vehicles, such as farm machinery, construction machinery or transportation vehicles, are often provided with a console extending along a side of the seat member for use as a support for armrests and steering devices such as a joystick or control panel. In particular, the joystick must be located within reach of the occupant when seated, which is why it is necessary to provide the joystick-equipped console with mobility in order to adjust its position according to the occupant's body shape. In previous vehicle seats, a first adjustment rail was mounted on the vehicle seat base, on top of which an adapter plate was mounted. Then, a second adjustment rail is attached to the adapter plate and the vehicle seat is mounted on top of the second adjustment rail. On the one hand, this means that when the console is adjusted, the seat part will also be adjusted, so that the distance between the seat part and the pedals or steering wheel needs to be readjusted. The distance is adjusted to follow a specific sequence. First, the distance between the seat member and the console must be adjusted, and then the distance between the console and the steering wheel, because moving the console also moves the seat member. Furthermore, the two adjustment rails may form a long lever arm, which can negatively affect the belt pull test. For this purpose, and due to a possible collision between the vehicle seat and the cabin wall of the commercial vehicle, the adjustment range of the two adjustment rails must be limited. Accordingly, it is an object to provide a vehicle seat in which an improved adjusting system reduces the space required for the adjusting system, in particular in the vertical direction, and improves comfort and safety. Disclosure of Invention The invention therefore provides a vehicle seat comprising a seat part that can be moved back and forth in a longitudinal direction and comprising a first console that can be moved back and forth in the longitudinal direction and a vehicle seat base, wherein the seat base is provided with at least one adjustment rail and a first slide attached thereto, wherein the first slide can be moved back and forth in the longitudinal direction by means of the at least one adjustment rail, wherein at least one spacer is provided on the first slide for firmly connecting the first slide to the seat part above it. The vehicle seat base is provided with a second slide device between the seat part and the first slide device. The first console is attached to the second slide, which also extends significantly on one side of the seat part. The second slide is slidable or rollable on the first slide in a longitudinal direction such that the second slide is movable relative to the first slide and the first console is movable relative to the seat member. 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. A console is a component that is disposed on one side of a vehicle seat as a support structure for various other components. In particular, an operating device such as a joystick, a control lever or a control button is attached to the console for controlling the vehicle or the connected equipment or machine. To ensure ease of operation, the console is adjustable in the longitudinal direction and in the height direction. Adjustment in the forward and rearward directions along the longitudinal direction is used to adjust the distance between the occupant's upper body and the console. For smaller occupants, it may be necessary to move the console and all of the operating devices closer to the upper body, i.e., push backward, depending on the length of the occupant's arms, so that the console and any operating devices can be comfortably used. 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. Typically, a vehicle seat has a vehicle seat base coupled to a vehicle body. The seat base typically has a spring system that dampens relative movement between the vehicle seat and the vehicle body in a vertical direc
