Systems and methods for modularly loading different driver seats including wheelchairs onto an off-road vehicle and an off-road vehicle including same

A modular seat loading system for removable loading of various driver seats onto an off-road vehicle (ORV), the modular seat loading system comprising at least:

• (a) at least one controllable length-adjustment device comprising at least one extendible apparatus directly or indirectly connectable to a frame of the ORV, the at least one controllable length-adjustment device being configured and positioned for controllable adjustment of angular position of a floor of the ORV that is fixedly connected to the frame of the ORV, by controlling length of the at least one extendible apparatus, enabling controllably achieving at least two ORV modes switchable therebetween:
• a load mode in which the ORV floor is tilted forming a tilted slope at a non-zero angle between the ORV floor and a ground surface plane, for loading and removing, upon requirement, a wheelchair or a wheel-less seat for serving as a driver seat of the ORV, for forming a modular wheelchair-accessible ORV;
• and
• a drive mode in which the ORV floor is lifted from the ground surface,
• (b) a load controller configured at least for adjusting length of the at least one controllable length-adjustment device,
• wherein the at least one controllable length-adjustment device is also used for controlling the movement suspension of the ORV by enabling natural expansion and contraction thereof in response to ORV movements and road conditions.
