The invention relates to vehicles propelled by the muscular energy of the driver, in particular to folding velomobile with variable in accordance with the height and weight of the driver ergonomic parameters.

Known taken as a prototype recumbent containing a frame in the form of longitudinal beams, front wheel drive, attached to the chassis with help motionless installed on the front forks, turning the rear wheel, attached to the chassis through the rear swivel forks, wheel, having the ability to tilt forward by the frictional mechanism associated with the rear wheel through a rotary mechanism, the actuator and drive sprocket rigidly mounted on the shaft, pedals and chain, seat, resiliently mounted on the frame, seatpost beam, a backrest mounted on the frame with the ability to change the angle and move along it with the regulating device equipped with mounting holes and installed on the front fork side supporting wheels and U-shaped buffer (see, for example, RF patent for the invention №2299826, IPC B62K 15/00, 17/00, 2006).

The disadvantage of this recumbent is an inconvenience in operation, in particular the high complexity of the changeover tricycle under growth driver due to the design of the actuator and regulating devices. About Yasnaya this fact, for this changeover should be removed, rearranged, and then re-attach the carriage drive sprocket and pedals on the wing front forks using the special tool, and change the position of the seat beam seat and rack with backrest by moving the respective locking pins on the regulating device.

Increases the inconvenience in operation and greater complexity of folding tricycle for storage or transportation, because it is necessary to translate the wheel in an inclined position by means of friction tilt mechanism, which provides no regulation of the necessary amount (the driver) effort (i.e. does not take into account the physical capabilities of the driver), and using the translate tool U-shaped buffer from the operating position (the side of the buffer are arranged horizontally in the position for storage and transportation (the side of the buffer are arranged vertically).

Because of the structural features of the mounting side of the supporting wheels is also required when mounting or Dismounting the use of special tools and the location of the wheels with offset forward relative to the center of gravity of the recumbent reduces their protective function - protection from falling over.

Another drawback is low comfortnet the driver's operation. This is due to the design features of the system depreciation seat in order to accommodate the compression spring only with a small stroke a certain rigidity (which is uncomfortable for drivers other weight) and does not allow the use of a shock absorber with adjustable stiffness (typical cycle). In addition, the seat is provided with an additional damping springs, and in the process of operation occurs the movement of the seat relative to the backrest, and since the shape of the backrest in the vertical plane does not match the shape of the back of the driver, it also creates discomfort in operation due to the additional load on the back, and thereby narrows the range of users of the tricycle, for example, by excluding potential users with certain medical restrictions.

Design features drive recumbent not only reduce the efficiency of the drive (due to the large amplitude of the vertical movement of the driver's feet) and create discomfort during the changeover to other ergonomic options (as mentioned above), but also reduce the comfort of the recumbent operation (large amplitude vertical and horizontal movement of the legs leads to the increased load on them), as well as increase the length of the tricycle, as located on the carriage pedal in to einem forward position beyond the size of the front wheels, and the buffer must be installed before the pedals.
