       29 . The method of  claim 28 , further comprising fastening a front part of the seat bottom unit by using one of a screw, a bolt, a latch, a captive screw, a quarter-turn fastener, a hook, and a spring clip, thereby generating a pressure at a contact surface between the tip of the locking members and the inner surface of the front wall of the connecting anchors of the backrest unit and forcing the connecting anchors of the backrest unit against the backrest connecting tubes of the support units, holding the hook shape of the locking members against the front wall of the connecting anchors of the backrest unit against vibration.  
   
   
       30 . The method of  claim 17 , the seat bottom unit having locking members, ends of the locking members having a teeth shape, said step engaging the seat bottom unit in locking engagement with the at least two support units and the backrest unit comprising inserting the locking members of the seat bottom unit into an aperture of connecting sliders of the supports units and through a perforation provided in backrest connecting tubes of the support units and a corresponding perforation provided in connecting anchors of the backrest unit located in the backrest connecting tubes of the support units; whereby lateral teeth of the ends of the locking members engage apertures provided in a rear inside wall of the connecting anchors of the backrest unit and corresponding apertures provided in a rear inside wall of the backrest connecting tube of the support means, a tightening action of a screw between angles and the seat bottom unit pushes the lateral teeth inside these apertures while a bridging part therebetween is blocked by a surface of the rear inside wall of the connecting anchors of the backrest unit.  
   
   
       31 . The method of  claim 17 , comprising providing a backrest unit comprising a frame made of a first tube inserted into second tubes, the first and second tubes being of different diameters and thicknesses, the first tube forming a shape of the backrest unit, the tubes, at a beginning of an impact, slide one against the other.
