A-Pillar Sun Visor Louver for Windshield Gap Glare Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sun visors for commercial vehicles often leave gaps between the A-pillar and the extended sun blind, allowing backlight/sunlight to enter and blind the driver, due to installation space and assembly constraints.
Innovation Solution
A device with a movable cover body connected to the A-pillar trim part, which can be pivoted into position to cover and shade the gap between the A-pillar and the sun blind, providing effective sunlight shielding without obstructing the view when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sun visors are arranged above the windshield, then they can provide sunlight shielding, but gaps remain between the A-pillar and the extended sun blind allowing backlight to enter
Solution Approach 1:
The sun protection system is divided into multiple segments: a conventional sun blind for general coverage and a separate A-pillar visor body for gap coverage. This segmentation allows each component to address specific areas, eliminating backlight entry through gaps while maintaining overall system simplicity.
Solution Approach 2:
The A-pillar visor body acts as an intermediary element that fills the gap between the conventional sun blind and the A-pillar. This intermediate component specifically addresses the uncovered area, preventing backlight from reaching the driver's eyes through the previously exposed gap.
2Object-affected harmful factors
If a movable visor body is added to cover the gap, then backlight shielding is improved, but the device complexity increases
Solution Approach 1:
The A-pillar visor body is merged with the existing trim part structure, utilizing the trim part as a mounting base. This integration approach combines the new visor function with existing vehicle interior components, reducing overall device complexity while achieving improved backlight shielding.
Solution Approach 2:
The visor body is designed with movable connection to the trim part, allowing it to be positioned as needed. This dynamic design enables the visor to be adjusted or removed if necessary, providing flexibility without permanently increasing structural complexity.
3Ease of operation
If the visor body is positioned to cover the gap, then driver visibility is improved, but space for movement is reduced
Solution Approach 1:
The visor body is specifically sized and shaped to cover only the gap area between the sun blind and A-pillar. This localized approach provides precise sunlight shielding where needed while minimizing the volume occupied by the visor, preserving space in other areas of the vehicle interior.

AI summary
The invention relates to a device (10) for shielding a motor vehicle from sunlight, comprising a trim panel (14) designed for the interior lining of an A-pillar of the motor vehicle, and a louver (12) movably connected to the trim panel (14). Advantageously, the device (10) according to the invention can, for example, cover and shade a gap between the A-pillar and a sunshade located above the windshield and extended. For this purpose, the movable louver (12) can be moved into a position of use in which it is positioned in the gap. The driver of the motor vehicle can thus be effectively shielded from dazzling glare/sunlight that could otherwise enter through the gap.
