Abstract
Device for vehicles, in particular fork-lift trucks, the device being designed at least for carrying out a steering movement of the vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device is at least partially rotatable about a first pivot axis relative to the arm rest, wherein rotation of the device about the first pivot axis causes the steering movement of the vehicle, and wherein the device comprises a first device element arranged above the arm rest, and a second device element which is fixedly connected to the first device element and extends downwards from the first device element beyond the first device element.

A device for vehicles, in particular fork-lift trucks, the device being designed at least for carrying out a steering movement of a vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device is at least partially rotatable about a first pivot axis relative to the arm rest, wherein rotation of the device about the first pivot axis causes the steering movement of the vehicle, wherein the device comprises:
- a first device element arranged above the arm rest, and
- a second device element which is fixedly connected to the first device element and extends downwards from the first device element beyond the first device element, and wherein the device comprises at least one rotatable wheel element which can be at least partially embraced on a circumferential side by fingers of a hand of a vehicle driver placed on the device and can be rotated about an axle for the steering movement, the second device element being fixedly connected to the wheel element and extending downwards from the wheel element beyond the wheel element.
A device for vehicles, the device being designed at least for carrying out a steering movement of a vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device has:
- a first device element arranged above the arm rest, and
- a second device element fixedly connected to the first device element and extending downwardly from the first device element beyond the first device element,
- wherein the device is arranged substantially rigidly relative to the arm rest and the steering movement of the vehicle is caused by means of a force action and/or a torque action on the device, and wherein the device comprises at least one rotatable wheel element that is at least partially embraceable on a circumferential side by fingers of a hand of a vehicle driver placed on the device and rotatable about an axle for a steering movement, the second device element being fixedly connected to the wheel element and extending downwards from the wheel element beyond the wheel element.
A device for vehicles, in particular fork-lift trucks, the device being designed at least for carrying out a steering movement of a vehicle, the device being arranged on an arm rest of a vehicle seat of the vehicle, wherein the device is rotatable about a first pivot axis relative to the arm rest, wherein rotation of the device at a pivot angle about the first pivot axis causes steering movement through a steering angle, a steering ratio being progressive from pivot angle to steering angle, wherein the device comprises:
- a first device element arranged above the arm rest,
- a second device element fixedly connected to the first device element, and
- at least one rotatable wheel element that is at least partially embraceable on a circumferential side by fingers of a hand of a vehicle driver placed on the device and that can be rotated about an axle for the steering movement, wherein the second device element is fixedly connected to the wheel element and extends downwards from the wheel element beyond the wheel element.
