1. A foldable roll-over protection structure for a vehicle moveable in a generally fore-and-aft direction, said foldable rollover protection structure comprising:
a frame including a base section and an upper section, said base section being connectable to the vehicle, said upper section being swingable relative to the base section between an upright position and a second position angularly offset relative to the upright position; a hinge assembly swingably interconnecting the sections of the frame; a first resilient vibration dampener operably coupled between the sections of the frame, said first vibration dampener being resiliently deformed when the upper section is in the upright position, such that relative vibrational movement between the frame sections is restricted; and a second resilient vibration dampener operably coupled between the sections of the frame, said second vibration dampener being resiliently deformed when the upper section is in the second position, such that relative vibrational movement between the frame sections is restricted. |
