  • a drive axis 24, disposed parallel to the axis of the motor 22, can rotate in rolling bearings 125 fixed in the steel profiles 13 and in rolling bearings 126 fixed in steel profiles 114 fixed to the chassis, parallel to the profiles 13.
  • the drive axis 24 is in fact constituted by the assembly of two axis elements joined end to end by means of an axis assembly sleeve 24R.
  • a toothed wheel 127 is fixed to each of the two ends of the drive axis 24, respectively meshing with the two toothed belts 110 whose notched face is located downwards.
  • Two free deflecting wheels 158 located respectively in front of and behind each toothed wheel 127 hold the toothed belt 110 in gear with almost half the circumference of this toothed wheel 127.
  • a toothed transmission belt 128 ensures the transmission between the toothed wheel 123, driven in rotation by the axis of the motor 22, and a toothed wheel 129 fixed on the drive axis 24.
  • the carriage 105 is connected to the panel 6Z of the shutter 4 by means of two gas piston buffers 30 and two connecting pieces 131.
  • the end of the cylinder 32 and the end of the piston rod 33 of each buffer 30 are fixed respectively to a pin fastening piece 134 fixed to a steel profile 13 of the chassis of the carriage 105 and to a pin fastening piece 135 fixed to the corresponding connecting piece 131, near one of the ends of it.
