Description

A SEATING SYSTEM WITH MODULAR CHAIRS FOR DYNAMIC SPACE

OPTIMIZATION

BACKGROUND

Technical Field of Invention

[001] The embodiments herein generally relate to a utility product and particularly relate to a modular chair and a seating system enabled through the modular chair for space optimization and variable spatial system. The embodiments herein more particularly relate to a seat having variable seat height systems alongwith angular seating systems to allow a raised comfort for a passenger as well as enhance space utility.

Description of Related Art

[002] A seating system and design of a seat to optimize of an airline seat is a seat on an airliner in which passengers are accommodated for the duration of the journey. Such seats are usually arranged in rows running across the airplane's fuselage. A diagram of such seats in an aircraft is called an aircraft seat map. The aircraft seat map are often published by airlines for informational purposes, and are of use to passengers for selection of their seat at booking or check-in. The airplane seat maps usually indicate the basic seating layout, the numbering and lettering of the seats, the location of the emergency exits, lavatories, galleys, bulkheads and wings. Airlines which allow internet check-in frequently present a seat map indicating free and occupied seats to the passenger so that they select their seat from it.

[003] One of the prior arts discloses a seating system the seats are swivellable about axes and arranged with their axes in column axes. The seats each have a direction extending from the middle of the seat back through the middle of the seat cushion, intersecting the seat's swivel axis. Extending equally on either side of the seat direction is defined a seat projection forwards of the seat cushion and having the same width as the seat cushion. The swivel is set up to allow the seat to be turned through 6 from 17.5 to the longitudinal axis of the column (and the aircraft to be equipped with the seats) to 23.5. At 17.5, as in column IV, the seats partially face the seats in front in the column. This is the maximum angle at which the regulatory authorities will allow a lap belt only to be worn by a passenger for TTL. When the seats are swivelled outwards to 23.5, they face the space alongside the seat in front and can be converted to bed mode.

[004] Another prior art discloses a seating system for passenger aircraft or other vehicles are detailed. Some system have seats positioned at offsets from a longitudinal axis of a vehicle cabin in either "V" shapes or herringbone patterns. Other systems include seats that are staggered within the cabin. Further systems include pairs of seat that are both parallel and offset from the longitudinal axis, but are placed so that feet of the port and starboard passengers point away from the fuselage.

[005] However, the seating system disclosed in the prior art leads to a plurality of real time problems like causing hindrance to the passengers during a lateral movement, less leg space, less flexible seats leading to high discomfort during sleeping resulting in more jet lag experience etc. To solve the comfort issue, many airlines and other transportation systems introduce the seat with high bending with respective to ground but again they limit or reduces the number of seats in a transport vehicle or craft.

[006] In the view of foregoing, there is a need for a seating system with an optimum space utilization and enhanced comfort experience. Also there is a need for a seat assembly to provide high flexing angle, less space and space optimization. Further there is a need for a seating system with dynamic space management allowing higher lateral and longitudinal movement (with respect to the vehicle length) to the passenger and vehicle or craft crew.

[007] The above mentioned shortcomings, disadvantages and problems are addressed herein, as detailed below. SUMMARY OF THE INVENTION
