Patent ID: 8403083

Claim:
A vehicle including a frame incorporated with a drive unit for enabling the frame to travel in a prescribed direction and a seat assembly supported by the frame; the seat assembly comprising: a pair of arm members extending laterally outward to either lateral side of the frame and each having a base end pivotally supported by the frame around a pivot center extending in a fore and aft direction; a pair of saddle members each pivotally supported by a free end of the corresponding arm member around another pivot center extending in a fore and aft direction, the saddle members defining a pair of seat surfaces, respectively, configured to jointly support buttocks of a vehicle occupant; a pair of spring members resiliently urging the arm members, respectively, in an upward direction; and a mechanism for maintaining the seat surface of each saddle member in an approximately horizontal orientation and converting a downward movement of each arm member against a spring force of the corresponding spring member into an inward tilting movement of the corresponding saddle member, the mechanism being configured such that downward displacements of the two saddle members may individually vary depending on distribution of load between the two saddle members.
