Interior trim generally refers to components and materials such as partitions, door trim panels, dashboard assemblies, armrests, and carpets in a car.
While interior trim is only an auxiliary part of a car, it plays a crucial role in vibration damping, heat insulation, sound absorption, and soundproofing, significantly impacting the car's comfort. Adding a suitable steering wheel cover not only increases the comfort of the grip but also enhances the driver's experience and enjoyment, while protecting the steering wheel from wear-a win-win situation. Steering wheel covers come in many types, categorized by material such as plush, velvet, thick fabric, imitation leather, leather, neoprene, rubber granules, and high-density lambskin with a thick lining. There are also improved materials, such as glow-in-the-dark leather, anti-slip particles, short-pile embroidery, and plush steering wheel covers with small plush toys. Adding a sunroof improves ventilation in the car, as the air quality directly affects passenger comfort. A sunroof also provides convenient conditions for driving photography and videography. Car sunroofs can be categorized by their opening mechanism into manual and electric types, and by their opening direction into recessed, sliding, tilting, and convertible types. Manual sunroofs are mainly of the tilting and convertible types.
