Abstract
A vehicle, in particular electric wheelchair, having a chassis and a driver's seat which is fastened thereto and can be set in its inclination with respect to the chassis. The vehicle includes an inclination sensor which determines the angular position (α) of the seat surface of the driver's seat with respect to the horizontal (H), an adjusting device which is connected to the chassis and to the driver's seat, and a control and regulating device which is operatively connected to the inclination sensor and the adjusting device and via which the driver's seat can be pivoted by the adjusting device in such a manner that its seat surface is always situated essentially parallel to the horizontal (H).
Claims19
A vehicle having a chassis and a driver's seat which can be set thereon in an inclination with respect to the chassis along two curved rails, comprising:
- an inclination sensor which determines an angular position (α) of a surface of the driver's seat with respect to the horizontal;
- an adjusting device which is connected to the chassis and the driver's seat;
- and
- a control and regulating device which is operatively connected to the inclination sensor and the adjusting device and via which the driver's seat can be pivoted by the adjusting device in such a manner that the seat surface is situated essentially parallel to the horizontal (H),
- wherein two guide rails are fastened to the driver's seat and are mounted in each case between at least two rollers connected in a positionally fixed manner to the chassis.
A vehicle, comprising:
- a chassis;
- a front mounting holder and a rear mounting holder, the front mounting holder being at a first height and the rear mounting holder being at a second height, different from the first height;
- a driver's seat mounted to the chassis via the front holder, the rear holder and a base plate;
- curved guide rails fastened to opposing sides of the driver's seat and guided by engaging rollers lying opposite one another in pairs and at different heights;
- an inclination sensor with which an angular position of a seat surface of the driver's seat with respect to a horizontal H is detected;
- an adjusting device which comprises a linear electric motor with telescopic rod is fastened to the driver's seat and one of the base plate and the chassis;
- and
- a control and regulating device connected to the inclination sensor and the adjusting device.

- an inclination sensor which determines an angular position (α) of a surface of the driver's seat with respect to the horizontal (H);
- an adjusting device which is connected to the chassis and the driver's seat;
- and
- a control and regulating device which is operatively connected to the inclination sensor and the adjusting device and via which the driver's seat can be pivoted by the adjusting device in such a manner that the seat surface is situated essentially parallel to the horizontal (H);
- wherein the driver's seat is pivoted about a virtual pivot point (P) when the vehicle travels downhill.
