However, on deployment but above all on rewinding, this cable runs the entire length of the drum, and thus occupies a footprint E71 and E7 respectively, here each illustrated by a gray triangle.
• FIG. 2 illustrates the functional geometry of a winch 1 mounted laterally on a frame side member 91, according to an exemplary embodiment of the invention.
• This winch comprises a drum 11, on which is wound the cable 8.
• This drum is rotatably mounted about its axis Ail, which is here parallel to the spar 91. It is mounted on a frame 19 which is fixed to the spar at attachment points 191, 192, here bolts passing through the frame and the spar to tighten them against each other.

• This distributor may be of a known type.
• the cable 8 is guided towards this point of hawse-hatch 14 by a return device 15, which thus fulfills the role of hawse-hatch.

• the two fixing points 191 and 192 are arranged on either side of the projection of said hawse point 14, that is to say that their respective orthogonal projections P191 and P192, on the axis of rotation Ail of the drum 11, are located on either side of the orthogonal projection P14 of the hawse point 14 on this same axis Ail.
• the frame in this example has a generally flattened shape, in the form of a plate, one of the faces of which, called the fixing surface 190, bears on the frame under the effect of the fixing means.

It will thus return the cable 8 in the two exit directions front DI and rear D2 along a path which remains very close to the spar, and with zero or substantially zero travel. This avoids the constraints created by the dimensions E71 and E72 of the prior art 7.
• the pull point by the cable on the drum which moves inside the angular sector S13 (shown in dotted lines), is thus always between the projections P191 and P192 of the two mounting points of the frame , and preferably between the two bearings 11 and 12 of the drum, and therefore without overhang.

• the invention thus makes it possible to use a less specific and therefore less expensive winch, or even a standard defludding winch of the type usually fixed to the front face of the vehicle, to fulfill the same function as the lateral installations currently existing. It also allows a significant weight saving, for example of the order of 50%. It also allows a mechanical stress on the frame, both by the reduction in mass and by the absence of overhang in its attachment to the frame, allowing for example a reduced bending moment of the order of 50 % to 90%. The installation is also facilitated because of the reduction in size, which is thus freed from the movement of the mobile suspension and steering elements.

• This combination is particularly advantageous because the synthetic cable makes it possible to use cross-cutting devices 13 and / or return 15 of a different technology, which allows greater compactness and better integration, directly on the winch-frame interface. This makes it possible to greatly increase or even simply make possible the advantages provided by this architecture, by allowing the synthetic cable to run along the frame in two opposite directions very closely.

• the guide surfaces 151, 152 are formed partially or exclusively by one or more friction surfaces, of a low friction material and on which the cable (8) slides by sliding. These surfaces can thus be produced fixed and over a restricted angular sector, for example of the order of 90 °.
