<p>The present invention relates to a frame structure (11) of a tractor vehicle, comprising a pair of longitudinal profile members (12,14) delimiting the frame laterally and extending towards the rear end of the vehicle. The profile members (12,14) each comprise a vertical web (16) and an upper flange (26) extending from the web (16) towards the inside of the frame (10), the upper sides of the longitudinal profile members (12,14) each comprising a horizontal section (22), followed by a downwardly declined end section at the rear end of the vehicle. This frame structure (11) is characterized in that the upper flanges (26) are cut-out or cut-off at least at the transition from the horizontal section to the end section, and the longitudinal profile members (12,14) are reinforced laterally by reinforcement profiles (32,34) that are flanged to the outer sides of the longitudinal profile members (12,14) and extend along their upper rims towards the rear end of the vehicle.</p> |
