Design of backdoor

                                                             Design Back Door

Introduction:

A car door is a type of door opening, typically hinged on its front edge, but sometimes attached by other mechanisms such as tracks, for entering and exiting a vehicle. Doors most often integrate side windows for visibility from inside the car and can be locked to secure the vehicle.

Car doors may be manually operated or with power assist supplied by the vehicle. Powered doors or power doors may be found on minivans, luxury vehicles, or modified cars.

Car doors are designed to facilitate ingress and egress by car passengers. Unlike other types of doors, the exterior side of the vehicle door contrasts in its design and finish from its interior side (the interior part is typically equipped with a door card or a door panel  that has decorative and functional features.

The exterior side of the door is designed of steel or other material like the rest of the vehicle's exterior. In addition, its decorative appearance, typically colored with a design, is intended to match with the rest of the vehicle's exterior, the central purpose being to add to the overall aesthetic appeal of the vehicle exterior.

A vehicle typically has two types of doors: front doors and rear doors. Loosely related are: vehicle hoods and vehicle trunk lids. There are also doors known as a "hatch" (see "door categorization" below)

A major safety issue with opened vehicle doors is the assumption at night vehicle doors can provide a warning to other vehicle drivers. These devices need not meet any US Federal Motor Vehicle Safety Standards since no standards apply. To make matters worse it was reported by the Fatal Accident Reporting System that in the year 2014 not one single death was reported with a person outside the opened vehicle door at night in the entire United States of America. New safety technology such as providing to the lower interior edge of the vehicle door a highly reflective tape provides the ability of other vehicle drivers to see the opened vehicle door at night.
