USSR author's certificate N 1188040 A1, B 62 K 15/00 (prototype) 1985.Known technical solutions are less comfortable, worst handling and ustoichivost what instruction has the following disadvantages: the seat of the driver consists of two parts: the seat and backrest with fluctuations around the steering hinge, which reduces comfort when riding and stability of the tricycle. The use of hands for pedaling with this design is problematic, (the author is not provided), as applying effort on the hands, You inevitably get to a seat back, which will change the direction of motion.The purpose of the invention to improve ride quality, comfort, stability, providing opportunities to use when moving the muscles of the arms, the separation structure of two compact part.To achieve this, the front part of the frame and the rear part, which by hinges and secured leaning in the direction of rotation driver seat, are interconnected via a Central node that performs the functions of the steering pivot, tilt mechanism, driver seat in the direction of rotation, the adjusting unit for changing the departure of the front frame respectively, the length of the legs of the driver, as well as separation recumbent on two compact part.In Fig. 1 shows the view of the recumbent side of Fig. 2 top view.Recumbent consists of three main parts. The front part 1, on which is fixed a driving wheel 2 with pedal actuator of the rear part 4 through the Central node 7, which contains the bearing assemblies 8 and 9, the steering arm 10, the device 11 adjustment of departure of the front frame 1, respectively, the length of the legs of the driver with locking bolts 12. The mechanism 13 tilt the driver's seat in the direction of rotation is fixed on the Central steering sleeve 14.In order to start moving on the tricycle, it is necessary to lower the hand brake, which serves as a latch on the lever the brake, and put torque on the pedal drive. 3. The Central unit 9 allows you to change the direction of motion as using the steering handle 10, and without hands, one body. While holding hands behind the knee pads are included in the pedaling muscles of the shoulder girdle. To stop the recumbent need to press the brake lever. 1. Recumbent, single, three-wheeled, consisting of three main parts, the front part with the leading wheel and pedal drive, rear mounted on it with a driver's seat and rear wheels, characterized in that, to improve handling characteristics, stability, provide opportunities to use when moving the muscles of the arms, the separation structure of two compact parts, the front part and the rear part soeda the driver in the direction of rotation, the adjustment of the node to change the departure front of, respectively, the length of the legs of the driver and the separation of recumbent on two compact part.2. Recumbent under item 1, characterized in that, for use in pedaling muscles in the arms, it is equipped with knee pads, and control is performed by a human trunk.
