The present invention provides a navigational aid for aiding a person driving a vehicle in maintaining a desired distance from a line of reference, and particularly a navigational aid for use in navigating agricultural vehicles. The navigational aid is mounted adjacent a window in the cab of the vehicle. The navigational aid comprises an upright elongate member, fixing means for fixing the elongate member adjacent the window of the vehicle, a pointer slidably mounted on the elongate member for movement between the top and bottom ends such that the pointer may be positioned to lie in a line of sight between an eye of the person and the line of reference thereby enabling the person to maintain the desired distance from the line of reference by driving the vehicle such that the pointer remains in the line of sight and appears to lie on the line of reference.

Cette invention concerne une aide à la conduite permettant au conducteur d'un véhicule de maintenir une distance donnée par rapport à une ligne de référence et, en particulier, une aide à la conduite de véhicules agricoles. L'objet de l'invention, monté près d'une des glaces de la cabine de conduite, comprend un élément vertical allongé, un moyen de fixation de cet élément près de la glace de la cabine de conduite et une mire montée sur l'élément vertical allongé et mobile entre les deux extrémités de celui-ci. Positionnée sur une ligne imaginaire reliant l'oeil du conducteur à la ligne de référence, la mire permet au conducteur de maintenir une distance donnée par rapport à cette ligne aussi longtemps que la mire demeure sur la ligne imaginaire susmentionnée et semble reposer sur la ligne de référence.
