15 Essential Car Interior Parts You Need to Know
In today's context, a car has become a necessary asset, providing a convenient and efficient mode of travel for both people and goods, enabling swift movement between diverse locations. A car comprises various interior and exterior parts, each playing a crucial role in its proper operation.
Car interiors include a variety of elements. Among the common components within a vehicle are the steering wheel, floor carpet, emergency flashes, ventilation controls, car seat, door panels, dashboard, and various electrical elements. Keep reading to delve deeper into the diverse interior parts of a car.
A headliner in a vehicle covers the ceiling with soft, color-coordinated fabric, hiding bare metal. It not only adds style but also provides insulation against heat and noise, while also concealing wiring and hardware for electrical components, antennas, and various other accessories.
A standard headliner comprises various layers, typically incorporating polyurethane foam. This foam is either sprayed or glued onto a headliner board, which is then affixed to the interior roof. This construction imparts a softer feel to the headliner and serves to insulate the interior against both heat and noise.
2. Steering Wheel
A steering wheel, also known as a driving wheel, a hand wheel, or simply a wheel, is a vital component of vehicle control. It is the part of the steering system directly operated by the driver, with the remainder of the steering system responding to the driver's inputs.
Besides its use in steering, the steering wheel usually has a button for the car's horn. In countries where driving is on the left side, the steering wheel is typically on the right side of the car (right-hand drive or RHD); it's the opposite in countries where driving is on the right side (left-hand drive or LHD).
3. Seat And Seat Belt
The car's internal system features a driver's seat and a passenger's seat, both equipped with seat belts. The seat beside the driver is referred to as the "front passenger seat," while passengers in the rear of the car occupy the "back seats" or "rear seats."
A seat belt, also called a safety belt, is a vehicle safety device designed to restrain the driver or a passenger in place during a collision or abrupt stop, minimizing the risk of injury. By lessening the force of secondary impacts, seat belts play a significant role in reducing the likelihood of severe injury or death in a traffic collision.
4. Floor Carpet
Footwear dirt can accumulate inside the car, causing an unhygienic environment and unpleasant odors. Quality flooring helps prevent the buildup of dust and water in the interiors, preserving the cleanliness of the underlying carpet.
Many cars are equipped with thin, often perforated floor mats made of lightweight plastic. Alternatively, larger rubber, plastic, or polymer mats with grooves, spikes, and corrugated sections are available. These mats can be removed and washed, eliminating the need to scrub the carpet.
5. Rearview Mirror
A rearview mirror, typically flat, is installed in cars and other vehicles to enable the driver to see behind through the rear window. It is complemented by one or more side-view mirrors on trucks, motorcycles, and bicycles, functioning as additional rearview mirrors.
In cars, the rearview mirror is commonly secured at the top of the windshield on a double-swivel mount. This allows for easy adjustment to accommodate the height and preferred viewing angle of any driver. Additionally, it is designed to swing harmlessly out of the way in the event of an impact by a vehicle occupant during a collision.
6. Door Trims
Next to the dashboard, door trims are essential interior components featuring many buttons and various features that enhance comfort and safety while driving. Door trims, or door panels in vehicles, are commonly covered with leather, either genuine or synthetic, adding to the overall aesthetics and comfort of the car's interior.
Ensuring the proper functionality of all buttons and features on the door panel requires regular care. Moreover, well-maintained door trims contribute to an attractive and fresh appearance of the car's interior.
An airbag is a safety system for vehicle occupants, using a bag that inflates rapidly and then deflates during a collision. It comprises an impact sensor, an airbag cushion, a flexible fabric bag, and an inflation module. Its purpose is to offer a vehicle occupant soft cushioning and restraint in the event of a collision
It can reduce injuries that may occur between the occupant and the vehicle's interior. Acting as an energy-absorbing surface, the airbag serves as a protective barrier between the occupants and potential impact points such as the steering wheel, body pillar, instrument panel, headliner, and windshield.
8. Clutch Pedal
The clutch pedal is the foot-operated pedal that allows the driver to control the vehicle's clutch. Positioned on the floor to the left of the brake pedal, the clutch is required for standing starts and is typically used (though not always) to synchronize the speeds of the engine and transmission during gear changes.
Pressing the clutch pedal closes the clutch, interrupting the power transfer from the engine to the transmission. Releasing the clutch pedal opens the clutch, initiating the power transfer process from the engine to the transmission.
9. Brake Pedal
The brake pedal is the foot-operated pedal used to slow down or stop a vehicle. When the driver presses the brake pedal, the system automatically applies the optimal pressure to prevent a collision with the vehicle in front. The brake pedal is situated on the floor to the left of the accelerator.
To engage the brakes, you use your right foot, keeping the heel on the ground, and apply force to the pedal. In vehicles with standard brakes, the pedal may move slightly before resisting. For power brakes, less pressure is required on the pedal to activate the brakes.
10. Gas Pedal
The gas pedal, also known as the accelerator pedal, is located on the right side of the car floor. Its primary function is to control the amount of gas supplied to the engine, therefore managing the car's speed. To accelerate, gradually press the gas pedal as your car gains speed.
Typically, the gas pedal and brake are operated by the right foot, while the left foot is used for the clutch. However, some drivers may mistakenly press the accelerator instead of the brake, resulting in sudden unintended acceleration and accidents. Additionally, there are drivers who deliberately practice left-foot braking.
11. Vehicle Audio
The audio system is a key component of a car's interior, offering both information and entertainment to passengers. It allows you to play songs based on your preferences, enhancing the overall experience of the vehicle.
In the early 1950s, vehicles were equipped with basic AM radio systems. Over time, technological advancements transformed these simple AM radios into multifunctional systems, incorporating features such as navigation systems, Blu-ray players, CD players, DVD players, cassette players, record players, 8-track cassette players, FM radios, and smartphone controllers like Android Auto and Apple CarPlay.
12. Cup Or Beverage Holder
A cup or beverage holder is a useful device serving as a car restaurant table or a drink holder while traveling. Known for its durability, sustainability, and user-friendly design, this feature is commonly found in cars, trains, trucks, ships, buses, airplanes, and even local transportation buses.
Cup holders are specifically designed to prevent cups, bottles, or containers from tipping over or spilling, minimizing the risk of spills inside the vehicle. Typically made of plastic or leather, these cup holders are high-temperature resistant, waterproof, and durable. They contribute to the aesthetics of the car interior while ensuring that spills are effectively contained.
13. Glove Compartment
A glove compartment, also called a glove box, is an enclosed area typically situated within the dashboard above the footwell of the front passenger seat in a vehicle. Despite its name suggesting storage for gloves, this compartment is used for miscellaneous storage purposes.
It is a convenient space for storing everyday items such as owner's manuals, insurance paperwork, napkins, maps, a flashlight, or a tire gauge. Its name is rooted in the compartment's initial purpose of storing driving gloves. In the past, these gloves were often kept in a box on the floorboard near the driver, giving rise to the term "glove box."
14. Air Ventilation
Most modern vehicles are equipped with an HVAC (heating, ventilation, and air conditioning) system. The primary purpose of this system is to regulate the air temperature inside the car as needed. Usually, the air conditioning system operates in two modes:
- The first method is air recirculation. In this mode, the air conditioner continuously circulates the air inside the car to cool it, creating a closed-loop system.
- The second method is the fresh air method. In this mode, the air duct at the front of the car is opened to draw external air into the vehicle.
Each mode, whether air recirculation or fresh air, has its own advantages and disadvantages.
15. Emergency Brake
An emergency brake, also known as a parking brake or handbrake, is a mechanism designed to securely keep the vehicle motionless when parked. Generally, emergency brakes include a pulling mechanism connected to a cable, which is linked to the two-wheel brakes of the vehicle.
In many vehicles, the parking brake remains fully mechanical. Traditionally activated by pulling a lever, the cables manually engage a portion of the car's braking system, commonly the rear disk or drum brakes. The mechanical design allows the driver to brake even if the main hydraulic system fails, providing an additional layer of safety.
