DESC:TECHNICAL FIELD
[0001] The present subject matter relates to a motor vehicle. More particularly, to a side door for a motor vehicle.

5 BACKGROUND

[0002] Typically, motor vehicles usually employ two or more side doors. The side doors are mechanically attached to a chassis frame structure of the motor vehicle. The side door enables ingress/egress passage defined in one or both sides of the motor
10 vehicle to allow access to the occupant’s area. Importantly, the side doors protect the occupants from damage by impact therefore high degree of reliability and strength is required.
[0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and therefore it
15 may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

DETAILED DESCRIPTION
[00019] In the following description, numerous details are set forth to provide a
10 thorough understanding of the embodiments. One skilled in the relevant art will recognize, however, that the techniques described herein can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring certain aspects.
15 [00020] Typically, while driving a motor vehicle the user needs to judge proximity to various objects and their relative velocities to make sound driving decisions such as whether or not there is enough time to overtake the vehicle or to change the lane. This judgment is made based on information obtained from the area surrounding the motor vehicle. To gather this information, the operator is frequently required to physically
20 turn her or his head to check for occupancy of a blind spot, for example. In taking such an action the attention of the user is invariably diverted from the control of the motor vehicle. Generally, all motor vehicles inherently have blind spots. The blind spot is an area hidden by parts of a vehicle structure. The blind spots are present all around the motor vehicle. The blind spots typically occur on either side of the motor vehicle. It is
25 observed that the most attentive driver could miss, a small obstacle like road curbs. This can cause harm to a pedestrian, and also damage to the motor vehicle. Importantly, the extent of damage depends upon the speed of the motor vehicle as at a higher speed any side collision increases the damage to the motor vehicle. More specially, the side collision can affect the alignment of the motor vehicle and can
30 damage a tire which can lead to a dangerous blowout. Further, it can bend a rim which can lead to wobbling. Importantly, any of the above phenomena affects the safety

characteristic of the vehicle. Therefore, to address the above-said issues, many systems are being designed which include various electronic devices like cameras, and improved side mirrors being added to the motor vehicles for visualization of the blind spot area. Typically, the side mirrors supplement the field of view by allowing the
5 vehicle user to access an additional field of view that encompasses a side environment of the motor vehicle.
[00021] However, a plurality of electronic drivers and complicated procedures are required to adjust the side mirror according to the height of the user. Therefore, it is observed that rarely do vehicle users adjust the side mirrors to desired optimal
10 orientation. This inhibition from users is often due to complex adjustment mechanisms and a time-consuming task, and the user may continue to use the motor vehicle with poor safety. Moreover, the side mirror positioned wrongly can exacerbate the risk rather than helping the blind spot detection problem. This can lead to major accidents especially when these vehicles are running and night on roads including unmetalled or
15 rugged roads. Therefore, to improve the safety of the occupants in the motor vehicle the thickness of the side doors and A-pillars are increased. This is, on the one hand, to achieve a high stiffness for safety and on the other hand for the accommodation of a variety of elements like an electric motor for power windows, cables, airbags, etc. However, this increases the blind spots as the side doors being configured to have
20 opaque and bulky design due to the use of sheet metal and the plurality of reinforcing bar inside the side door to prevent occupants from side crash. Importantly, in heavy commercial vehicles, the blind spots due to the side door can be minimized by providing a large retractable window of the side door. However, this is not feasible in light commercial vehicles due to different safety characteristics because of their
25 compact design, lower H – point of the occupants, and eye locations.
[00022] Thus, it is a challenge for design engineers to meet conflicting requirements of reducing the blind spots and improving the safety characteristics of the motor vehicle. Therefore, there is a need to provide an improved side door for a motor vehicle overcoming all the above problems & trade-offs as well as overcoming problems of
30 the known art.

[00023] It is an object of the present invention to eliminate the blind spot due to the side door on either side of the motor vehicle thereby reducing accidents caused by the failure of the user to even a minor object.
[00024] It is another object of the present invention to provide an accurate location
5 of the object relate to the host vehicle, road geometry such as steep hills, and sharps curves, roadsides, or road curbs without turning her or his head.
[00025] It is yet another object of the present invention, is to provide a lightweight without compromising the safety characteristics of the motor vehicle.

First manikin (601A) placed on a driver seat (602A), and the second manikin (601B) placed on the left side front seat (602B). The left side door (101A) of the motor vehicle (100) having a polygon shape cut out portion (102A, 103A) allows the driver to see obstruction (603) without the need of turning
30 their head in the direction of the obstruction irrespective of the height of the driver. More specifically, this eliminates the need to move the line of sight by looking for the

obstruction (603) like road curb while driving. The polygon shape cut out portion (102A, 103A) allows the driver to see better around the obstruction and allows the driver better depth perception especially, road curbs. This gives flexibility to the driver to park the vehicle very close to the road curb.
5 [00062] According to the present invention, the shape of the first and second dipped cut portion being configured to provide better visibility without comprising the safety of the occupants to bear the side collision specifically in vehicles having lower H- point. This reduces the serious accidents due to side collisions.
[00063] According to the present invention, the reinforcing member being
10 configured to have a substantially circular cross-section surrounding the transparent member being configured to bear the lateral impact thereby reduces the injury risks in case of a side collision.
[00064] According to the present invention, the side door being provided with first and second dipped cut out portion reduces the overall weight of the side door thereby
15 provides ease of operation especially for children.
[00065] According to the present invention, the transparent member improves the aesthetic appeal of the motor vehicle, still, the side door accommodates the plurality of cables and opening and locating mechanisms that are not externally visible. [00066] The above-described embodiments, and particularly any “preferred”
20 embodiments, are possible examples of implementations and merely set forth for a clear understanding of the principles of the invention. It will be apparent to those skilled in the art that changes in form, connection, and detail may be made therein without departing from the spirit and scope of the invention.
