The present invention relates to a vehicle and more particularly, to a seat of the vehicle.
BACKGROUND
The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.
Vehicle particularly, vehicle such as a scooter, a motorcycle, or a three-wheeler comprises a seat which provides seating for at least one of a rider and a passenger of the vehicle. The seat may be a single seat unit extending in the front-rear direction for seating both the rider and the passenger, or may be split seats for individually seating the rider and the passenger.
Further, some vehicle owners would like to convert their scooter from a multiple seat to a single seat to create more luggage space at rear and to use the rear storage space as a carrier. Moreover so, the owners can also keep different sort of containers in the rear space. The single sitting configuration should be in line with the basic design of the vehicle.
The rear seat of the split seat arrangements are mounted on frame of the vehicle by means of fasteners, for example - rear seat is bolted to the frame. Furthermore, the rear seats of split-seat arrangements require a separate locking mechanism to facilitate locking/unlocking of the rear seats. Further, in vehicles where seat is a split seat structure, both the seats require independent pivots, hence both the seats are to be opened independently causes inconvenience to the user, also this adds in the overall cost of the vehicle.
Thus, there is a need of a convertible seat assembly which provides versatility and provides ease of switching from multiple seat to single seat without much effort by the user and also gives an aesthetic appearance to the vehicle.
SUMMARY
The one or more shortcomings of the prior art are overcome by the system/assembly as claimed, and additional advantages are provided through the provision of the

system/assembly as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.

The disclosure further comprises a body frame of the vehicle. The seat is hinged to the body frame by a hinge. At least one opening is defined on the body frame and at least one protrusion is defined on an underside of the seat. The at least one protrusion configured to be connected in the at least one opening to removably secure the seat of the vehicle.
One advantage of the present invention is the passenger seat is detachably coupled with the rider seat, thus user can engage and disengage the passenger seat from the rider seat as per choice and requirement. This gives more freedom to the user to convert the vehicle from a two-seater to a single seater. Further, rider seat and a passenger seat need not be opened independently, and since the rear seat is joined to the rider seat, passenger seat opens whenever the rider seat is opened.
In an embodiment, a sub-frame is connectable to the body frame of the vehicle by at least one fastener.
In an embodiment, the passenger seat has a front end and a rear end and the first end of the passenger seat is configured to be hingably connected with the rider seat.
In an embodiment, the rear end of the passenger seat is releasably mounted on the sub frame by the at least one protrusion projecting outwardly from the underside of the rear end of the passenger seat.
In an embodiment, at least one opening are adapted to receive rubber grommets to receive respective protrusions.
In an embodiment, the seat is hinged to the body frame by a hinge.

In an embodiment, the front end of the passenger seat is supported by a plurality of seat resting rubbers provided on the sub-frame.
In an embodiment, the rider seat is lockable to the body frame of the vehicle by a latching device. The latching device is actuated by a latching cable thereof.
In an embodiment, the at least one protrusion is dislodged from the at least one opening to release the rear end of the passenger seat by application of force.
In another embodiment, a seat of a two-wheeled vehicle is disclosed. The seat comprises a first seat and a second seat. The first seat and the second seat are pivotably fixed to each other. A mounting unit is connectable to a frame of the vehicle. The mounting unit is configurable to receive the seat. At least one opening is defined on a surface of the mounting unit. At least one protrusion is defined on an underside of the seat. The at least one protrusion is configured to be received in the plurality of openings to secure the seat of the vehicle.
In a further embodiment, a method for unlocking a rider seat and a passenger seat of a vehicle is disclosed. The method comprises actuating a latching device by actuating means to facilitate unlocking the rider seat. The method further comprises the step of applying an upward force at second end of the passenger seat to disengage at least one protrusion from at least one opening on the subframe and rotating the rider seat about a hinge and thereby opening of the passenger seat along with the rider seat.
Since the rider seat and the passenger seat are pivotal to each other, upon locking the rider seat to the frame of the vehicle the passenger seat tends rattle due to the play between the rider seat and the passenger seat. Since the at least one protrusion is configured to be received in the at least one opening on the sub-frame such tendency to rattle can be controlled. The mounting of passenger seat on to the sub-frame of the vehicle by positioning rubber grommets in between the passenger seat and the sub-frame prevents rattling of the passenger seat.
