Suicide Doors On A Car

Suicide Doors: A Deep Dive into History, Mechanics, and Modern Relevance

Suicide doors, also known as rear-hinged doors or coach doors, are a fascinating automotive feature that evokes a sense of nostalgia and luxury. This article explores the history of suicide doors, delves into their mechanics, examines their safety implications, and discusses their current relevance in the automotive landscape. We'll unpack the reasons behind their popularity in the past and their relative scarcity today, offering a comprehensive look at this unique automotive element.

A Glimpse into History: The Rise and Fall (and Potential Rise?) of Suicide Doors

The term "suicide door" is somewhat morbid, originating from the perceived danger of passengers exiting the vehicle on the street side of traffic. Ironically, this seemingly inherent risk didn't initially prevent their widespread adoption. Early automobiles, particularly luxury models and limousines, frequently featured rear-hinged doors. This design choice wasn't purely aesthetic; it offered significant practical advantages.

In the early days of motoring, before power windows and central locking were commonplace, rear-hinged doors provided easier access, particularly for passengers in the back seat of larger vehicles. The absence of a B-pillar (the central pillar between the front and rear doors) allowed for a wider opening, making entry and exit considerably easier, especially for those with limited mobility or wearing formal attire. This was particularly appealing to chauffeured vehicles and high-end models that catered to a clientele prioritizing comfort and elegance.

Notable examples from the golden age of automotive design include the Rolls-Royce Phantom, various Cadillac models (especially those of the 1930s and 40s), and even some early Ford models. These vehicles cemented the image of suicide doors as a mark of prestige and sophistication. However, as automotive technology advanced and safety regulations tightened, their popularity waned significantly.

The Mechanics Behind the Design: More Than Just Hinges

The fundamental difference between a suicide door and a conventionally hinged door lies in the location of the hinges. Instead of being mounted on the front edge of the door, suicide doors are hinged at the rear, allowing them to open outwards, away from the vehicle. This seemingly simple alteration has significant mechanical implications.

1. Hinges and Mechanisms: The hinges themselves are robustly constructed to withstand the forces involved in opening and closing a larger door. These hinges often incorporate features to ensure smooth operation and prevent sagging or misalignment over time. In some higher-end applications, sophisticated dampening mechanisms might be used to control the door's closing speed, preventing slamming.

2. Latching Mechanisms: The latching mechanisms on suicide doors are equally crucial. They need to be secure, reliable, and able to withstand the outward forces exerted on the door when closed. These often involve multiple locking points for added security. Modern versions often integrate with central locking systems for ease of use.

3. Body Structure Integration: The body structure of a vehicle employing suicide doors needs to be carefully designed to accommodate the outward-opening doors. This includes considerations for the door's impact on the side profile, the potential for interference with neighboring body panels, and the necessary reinforcement to handle the stresses imposed during a collision.

4. Safety Features: Modern suicide door designs frequently incorporate safety features such as impact beams within the door structure, side-impact airbags, and reinforced hinges to mitigate the risks associated with the outward-opening mechanism.

Safety Concerns and Regulatory Hurdles

The primary reason for the decline in popularity of suicide doors is the inherent safety concerns associated with their design. The outward-opening nature means that a passenger exiting the vehicle might swing the door directly into the path of oncoming traffic, increasing the risk of collisions. This risk is significantly amplified in areas with heavy traffic or limited visibility.

This safety concern isn't theoretical; it has led to numerous accidents and legal issues over the years. This has subsequently led to regulatory hurdles and stringent safety standards that many manufacturers find difficult to overcome. The cost and complexity of implementing safety features to meet these standards often outweigh the potential benefits of the rear-hinged design. Consequently, very few modern cars incorporate suicide doors.

Modern Applications and Design Innovations

Despite their reduced prevalence, suicide doors haven't entirely disappeared from the automotive scene. They continue to feature (though sparingly) in some high-end luxury vehicles and custom-built cars, often as a design flourish or a nod to classic automotive aesthetics. Some modern adaptations attempt to mitigate the safety risks through technological solutions.

For example, some designs incorporate sensors that detect approaching vehicles or obstacles. If an obstacle is detected, the system might prevent the door from fully opening or alert the passenger to the potential danger. These features, while promising, add significant cost and complexity to the system.

FAQ: Addressing Common Questions About Suicide Doors

Q: Are suicide doors illegal?

A: Suicide doors are not inherently illegal in most regions. However, stringent safety regulations often make their integration into mass-produced vehicles impractical and expensive. The design needs to meet strict safety standards to comply with regulations.

Q: Why aren't suicide doors more common?

A: The main reason is safety concerns. The outward-opening design poses a significant risk of collisions, particularly when passengers exit the car onto a busy street. Addressing these safety concerns through engineering solutions significantly increases the cost and complexity of the design.

Q: What are the advantages of suicide doors?

A: The main advantages are increased ease of access, especially for rear passengers in larger vehicles, and improved aesthetics. The absence of a B-pillar allows for a larger opening, making entry and exit more convenient.

Q: What cars have suicide doors?

A: While rare in modern production vehicles, suicide doors have appeared on several luxury models throughout history, including various Rolls-Royce and Cadillac models. They are more commonly found in custom builds and some limited-edition vehicles.

Conclusion: A Legacy of Style and Safety Challenges

Suicide doors represent a fascinating intersection of automotive history, design, and safety. Their elegant aesthetic and enhanced passenger access have created a lasting legacy. However, the inherent safety concerns associated with their outward-opening mechanism have led to their diminished popularity in modern vehicles. While unlikely to make a mass-market comeback, suicide doors continue to intrigue and appeal to automotive enthusiasts, showcasing a unique chapter in automotive engineering and design. The technological advancements in safety mechanisms may eventually lead to a revival of this distinctive automotive feature, balancing style and safety in a way that meets contemporary standards. Only time will tell if this iconic design element will reclaim its position in the mainstream automotive world.
