TECHNICAL FIELD
[0001] The present subject matter relates to a three-wheeled vehicle. More
particularly, the present invention relates to a modified chassis supporting at least one passenger seat assembly for the three-wheeled vehicle.
BACKGROUND
[0002] In many of the developing & under developed countries, a motor
vehicle particularly a three-wheeled automotive vehicle is a significant mode of public transportation. It is vastly used as a point to point mode of transport in rural and urban areas. Though such vehicle is designed to bear the load of four people, generally it is overloaded and is operated intermittently for 12 to 14 hours a day to enable the driver to maximize his earnings. However, some of them lack safety reliability and are uneconomical.
[0003] An existing three-wheeled vehicle includes a driver compartment in a
front side having a front seat for a driver, and a passenger compartment at a rear side with a rear seat assembly for passengers, and is also provided with a seat back portion for accommodating luggage.
[0004] In another known passenger carrying vehicle, an additional seat
assembly is added to increase the passenger capacity of said vehicle. However, such vehicle chassis is supported by four wheels, two front and two rear wheels and provides rigidity to the vehicle and thus prevents the vehicle body from any side impact.
[0005] The three-wheeled vehicle suffers from disadvantage of having a
vehicle chassis being supported on three wheels. The vehicle with one front wheel and two rear wheel do not have capacity to accommodate more than one passenger seat assembly. However, such vehicles if provided with more than one passenger rear seat can cause sagging, bending and deformation of vehicle body from any impact applied sideways to the vehicle and hence may also result in lack of protection to the passengers. Thus, the existing chassis for the three-wheeled

vehicle heeds to be extended through addition of one or more cross members along at least one longitudinal members of a frame structure of the vehicle.
SUMMARY OF THE INVENTION
[0006] With the above objectives in view, the prevent invention discloses a
three wheeled vehicle with a modified chassis supporting at least one passenger seat assembly. More specifically, said present subject provides a three-wheeled vehicle body structure having an increased stiffness and rigidity and an increased safety to the passengers.
[0007] It is an object of the present invention to provide the three-wheeled
vehicle with a pair of vertical supports projecting laterally from opposite sides of said floor panel and being rigidly attached to at least one pillar structure of said vehicle and also said three-wheeled vehicle comprises of a front member extending transversely between said at least one pillar structure and being secured to said floor panel. Said pair of vertical members and said front member provides stiffness to a body panel of said vehicle and prevents from sagging and bending.
[0008] It is another object of the invention to provide a three-wheeled
vehicle with at least one battery box being secured on a retractable tray through a locking and a sliding arrangement.
[0009] It is yet another object of the present invention to provide a
three-wheeled vehicle wherein said pair of said vertical members, front member attached to said floor panel to form a hollow interior for securing said at least one battery box. However, where a vehicle is powered by an internal combustion engine, the hollow interior can be used to secure luggage.
[00010] It is still another object of the present invention to provide a yehicle comprising of at least one passenger seat assembly including a first seat assembly and a second passenger seat assembly, and wherein said first passenger seat is disposed opposite to said second passenger seat assembly in said a passenger compartment of said vehicle and further said first passenger seat assembly of said

at least one passenger seat assembly is disposed on an open top portion of said hollow interior.
[00011] As per first and second embodiments of the present invention said three wheeled vehicle comprises of said pair of vertical members projecting laterally from opposite sides of said floor panel and being rigidly attached to said at least one pillar structure, said front member being secured transversely between said first pillar structure and said second pillar structure. Said pair of vertical members are connected by a front member being secured to said floor panel along a transverse direction of said vehicle and said pair of said side members and said front member are attached to said floor panel in a manner so as to form said hollow interior for securing a battery box or luggage therein and further said first passenger seat assembly of said at least one passenger seat assembly is disposed on an open top portion of said hollow interior. In a second embodiment of the present said pair of vertical members comprises of an opening member as a door panel allowing the pane! manually opened and said retractable tray to slide within the opening such that said at least one battery box can be accessed.
