AI Technical Summary

Technical Problem

Existing 'glass-in-glass' windows in vehicles suffer from poor structural solidity and obstructed visibility due to the movable panel being centered, leading to weak and narrow glass portions and obstructing tracks or rails.

Method used

The window structure incorporates a supporting structure with a frame made of metal or composite material, minimizing its width while maximizing the opening size, and positions the track and movable panel outside the vehicle compartment to enhance robustness and visibility.

Benefits of technology

The solution provides a robust and unobstructed view by maintaining the 'glass-in-glass' configuration with minimal structural dimensions, ensuring a wider opening and improved visibility.
