Headrests and Armrests
Polyurethane (PU) foam is widely used in automotive interiors, particularly in armrests and headrests, where comfort, durability, and design flexibility are essential. Its ability to be molded into complex shapes and maintain its properties over time makes it ideal for these applications.
Description
Armrests
In armrests, polyurethane foam provides a soft yet supportive surface that enhances passenger comfort. It is often used in the form of integral skin foam, which combines a soft inner core with a tough outer layer. This construction delivers a smooth finish that resists wear, scratches, and environmental exposure.
Headrests
In headrests, polyurethane foam serves both comfort and safety functions. Typically made from high-resilience (HR) foam, it helps absorb impact forces in the event of a collision while offering comfortable head support during normal use. The foam’s ability to recover its shape after compression ensures it remains effective and comfortable over time.
Armrests Key Benefits:
- Provides ergonomic support for elbows and arms
- Maintains shape and performance over long-term use
- Offers a durable surface resistant to abrasion and UV exposure
- Compatible with various coverings such as fabric, vinyl, and leather
Headrests Key Benefits:
- Provides cushioning and head support
- Absorbs impact energy in rear-end collisions
- Retains shape under frequent use and pressure
- Easily molded to fit ergonomic and safety requirements
Material and Manufacturing Considerations
- Polyurethane foam can be customized in terms of density and firmness to meet specific comfort or safety needs.
- It is often molded directly onto structural components, ensuring precise fit and integration into interior assemblies.
- The foam is lightweight, contributing to vehicle weight reduction without compromising durability or performance.
