摘要

A support wall (2) of a public transportation vehicle includes a fixing device (8) of a module integrating a sighting axis (4) fixed to the wall by a screwed connection of attachment (208) comprising two positions which are intended to form a sighting axis of the apparatus. The fixing device (8) comprises two parts of the adjustment (100a and 100b) fixed by a screwed connection of the adjustment (105a, 105b) against a face of the wall and which each include a centering point (102a, 102b) arranged respectively facing - to - of the two points for positioning the module. The screwed connections include a hole and an element, the hole defining a plane of the adjustment of the element so that the straight line passing through the points of the centering closes the predefined angle (θ) with the vertical axis (yy ') of the wall.
