FIELD OF INVENTION
[0001] The present invention relates to a vehicle and more particularly, to a seat
of the vehicle.
BACKGROUND
[0002] Vehicle particularly, vehicle such as a scooter, a motorcycle, or a trike
comprises a seat providing seating for at least one of a rider and a passenger of the vehicle. The seat may be a single seat extending in the front-rear direction for seating both the rider and the passenger, or may be multiple seats for individually seating the rider and the passenger. Typically, in scooters, the seat is not only used for a seating arrangement but also as a closing for the storage compartment and in case of multiple split arrangement of the seat, front seat and rear seat close two separate storage compartments. Two latching mechanisms are to be used to restrict easy access of the storage compartments positioned below the front seat and the rear seat, this increases the number of parts to be used and overall cost of the vehicle, which is undesirable.
[0003] Further, some scooter owners would welcome to convert their scooter
from a tandem seat to a single seat to create more luggage space at rear and to use the rear storage space as a carrier. The single sitting configuration should blend into the basic design of the vehicle. Moreover, some scooter owners would welcome to use their scooter as a tandem seat to create more sitting area for rider and passenger, without affecting the basic storage facility available below the seat such as for helmet storage. Thus there is a need of a convertible seat assembly which provides versatility and has a stylish appearance of vehicle.
SUMMARY OF INVENTION
[0004] This Summary is provided to introduce a selection of concepts in a
simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key or essential features of the claimed subject

matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[00072] A method of unlocking the rider seat (112) and the passenger seat (170) includes following steps: 1. to unlock the rider seat (112) and the passenger seat (170), the user actuates the latching device (131) by the actuating means (155) to unlock the hook (162) of the rider seat (112) from the latching device (131). 2. this enable a

rotation of the passenger seat (170) with respect to the rider seat (112) thus the guide member (174) disengages from the guide member receiving portion (151) to gain access of the at least one storage structure (101) disposed in between the left seat rail (128) and the right seat rail (130).
[00073] The present invention relates to the seat (125) of vehicle (100). The seat (125) includes the rider seat (112) and the passenger seat (170). The passenger seat (170) is detachably attached to the rider seat (112), this enable the vehicle into a convertible seat option which can be converted from a two seater to a single seater, thus user can convert their scooter from a tandem seat to a single seat to create more luggage space at rear and to use the rear storage space as a carrier. Moreover, user can also use their scooter as a tandem seat to create more sitting area for rider and passenger, without affecting the basic storage facility available below the seat such as for helmet storage. This provides more versatility and has a stylish appearance to vehicle.
[00074] The seat (125) closes the opening to the at least one storage unit (101),
thereby preventing unwarranted access of the at least one storage unit (101). The configuration of the disclosed seat (125) is such that only a single latching device (131) is used to lock both the rider seat (112) and the passenger seat (170), thereby providing a cost effective solution as compared to conventional system where multiple latch devices were used. The seat (125) further provides different configuration of the vehicle (100) with removal and addition of the passenger seat (170) to the rider seat (112).
[00075] While few embodiments of the present invention have been described above, it is to be understood that the invention is not limited to the above embodiments and modifications may be appropriately made thereto within the spirit and scope of the invention.
[00076] While considerable emphasis has been placed herein on the particular features of this invention, it will be appreciated that various modifications can be

made, and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other modifications in the nature of the invention or the preferred embodiments will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
