Adaptive ergonomic steering column for commercial vehicles

A method of installing a new steering system of a commercial vehicle, the method comprising:

• removing an existing steering system of the commercial vehicle;
• and
• installing the new steering system in the commercial vehicle, the new steering system comprising:
• a pivot part, having a first connection point and a second connection point;
• a mounting bracket, having a jacket tube disposed inside a fixed mounting tube, a bracket portion connected at a first end to a fluid cylinder, and a second end pivotably connected to the pivot part at the first connection point;
• the fixed mounting tube configured to receive the jacket tube of the mounting bracket, the fixed mounting tube having a first friction flap, a first external flange bracket for receiving a bolt, and a second friction flap having a second external flange bracket for receiving a nut;
• the fluid cylinder having a first end fixed to the mounting bracket, a second end pivotably connected to the pivot part at the second connection point, and a relief valve;
• a handle rotatably connected to the fixed mounting tube via a bolt, and movable between a closed position and an open position,
• wherein when the handle is rotated from the closed position to the open position, the bolt rotates relative to the nut so as to permit the first and second friction flaps to loosen and thereby permit the mounting bracket to slide relative to the fixed mounting tube and to permit telescopic movement of the steering column, and
• wherein rotation of the handle from the closed position to the open position causes the relief valve of the fluid cylinder to open via a steel strand, and permit the fluid cylinder to change its length and thereby to permit the pivot part to pivot about the second connection point.
