<p>The chassis frame comprises two side chassis assemblies 6, interconnected by a rear linkage 21, each side assembly 6 being constituted by at least one main support element 8 and by a rear upright member 9. Each member 9 is articulated at its lower part to another chassis element 10 and at its upper part, to the support element 8 about a transverse axis 18, fixed in relation to the support element. The upright member 9 is in two sections 9a and 9b, one slidable within the other so that the member 9 has a variable effective length. The rear linkage 21 has a very small height and slides on section 9a of the upright member 9 via sleeve 28, and is pivoted at 26 to the lower section 9b. <IMAGE></p> |
