Ergometric stationary equipment suitable for training, diagnostic or rehabilitation purposes

An ergometric stationary piece of equipment comprising:

• a base member,
• a pedal unit arranged on the base member including a hub which is rotatable about a pedal unit axis,
• a carrier element connected to the base member such that it can pivot relative to the base about an axis parallel to the pedal unit axis, and
• a seat unit pivotally connected to the carrier element such that the seat unit and the carrier element may be selectively adjusted into different pivot positions, the seat unit including a seat surface, the pivot axis of the carrier element being proximate the pedal unit axis so that the difference between the greatest distance and the least distance occurring from the seat surface to the pedal unit axis is less than ten percent of the average distance between the seat surface and the pedal unit axis in the different pivot positions of the carrier element, and
• a mechanism for maintaining a constant inclination of the seat surface relative to the base when the carrier element pivots into different positions, the seat surface inclination maintenance mechanism comprising a parallelogram linkage including the carrier element and a guide member which is pivotally connected to the base member and the seat unit.
