![]() ĭoors that are for passenger egress are counted in North American markets. In Europe, the American-style labeling is occasionally used. In the case of saloons or sedans and coupés, the boot/trunk lid is not counted as a door by definition because it is for a separate storage compartment - these cars are marketed as 'two-door' or 'four-door'. ![]() Hatchback and estate or station wagon vehicles are typically described as 'three-door' or 'five-door' models in Europe and some other parts of the world. Hatchback doors and number of doors designation ĪMC Gremlin two-door with rear cargo hatch opened Door brakes were then introduced to slow down the door just before the door closed to prevent damage these soon became standard. Soon after, automotive manufacturers managed to construct lighter doors, but users were used to closing doors with significant force therefore doors could become damaged. The current trend is to have a three-stage door brake.ĭoor brakes exist because the doors on the first vehicles were heavy, so they had to be pushed hard to make them close. Vehicle doors often include brakes, or 'stays', that slow the door down just before it closes, and also prevent the door from opening further than its design specification. Other cars, particularly older US-manufactured vans, have hinged windows with a folded lever mechanism to push and hold the window out from its closed position. In the past, certain retracting windows were operated by direct (up or down) pressure, and were held in the up position by friction instead of by an internal lift mechanism. Most car door windows retract downwards into the body of the doors and are opened either with a manual crank, or switchable electrical motor (electric car windows other than the driver's window can usually be controlled at both the door itself and centrally by an additional control at the driver's position). Most vehicle doors have windows, and most of these may be opened to various extents. In American cars from the 1950s-1990s, they had buzzers or "door dingers" that sounded, along with the check light, whenever any door is open. The door light is standard equipment on all cars. 3d 725 (1978), in which the Supreme Court of California merged strict product liability with comparative fault, and thereby affirmed the right of General Motors to introduce evidence that decedent Kirk Daly flew out of his Opel not only because the door popped open, but because he was intoxicated and not wearing a seat belt.ĭoor switches are simple on/off mechanisms connected to the interior light (dome light), and may also be connected to a warning light, speaker, or other devices, to inform the driver when the door is not closed. A death that occurred exactly that way led to the landmark legal case of Daly v. The unfortunate side effect of this design was that external objects which touched a vehicle during a spinout could trigger the latch the door would pop open and eject the vehicle occupants. As late as the 1970s, some vehicles used exposed push buttons to operate the door latch, such as certain Opel models. Vehicle door latches on practically all vehicles today are usually operated by use of a handle which requires the user to pull, lift, or tug - with some force towards themselves rather than push. These are also frequently used on police cars, to prevent suspect criminals from escaping whilst in police custody. Also, they may be operated by remote control, with the transmitter often integrated into the main vehicle access and a key for the ignition.Īdditionally, rear passenger doors are frequently fitted with child safety locks to prevent children from exiting the vehicle unless the door is opened from the exterior. Door locks may be manually, or automatically operated, and may be centrally or individually operated. There are a variety of car door locking systems. ![]() Most vehicle doors are secured closed to the vehicle body with latches that may be locked to prevent unauthorized access from the exterior. ![]() Power door locks, which can work on a remote system.There are also doors known as a " hatch" (see " door categorization" below). Loosely related are: vehicle hoods and vehicle trunk lids. 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.Ī vehicle typically has two types of doors: front doors and rear doors. The exterior side of the door is designed of steel or other material like the rest of the vehicle's exterior. 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 (in British English) or a door panel (in American English) that has decorative and functional features. Car doors are designed to facilitate ingress and egress by car passengers. ![]()
