AI Technical Summary

Technical Problem

Existing retroreflective devices for motor vehicles do not achieve a balanced combination of high reflectivity for safety and compliance with regulatory requirements, while also ensuring a visually cohesive appearance and advantageous accident behavior.

Method used

A retroreflective device comprising two cover plates, one with high reflectivity and one with low or no reflectivity, designed to appear identical but functionally distinct, allowing the low reflectivity plate to detach upon impact without violating regulatory standards, thus enhancing safety and visual cohesion.

Benefits of technology

The solution provides high reflectivity for safety while maintaining a cohesive visual appearance and ensuring compliance with regulatory standards by allowing the low reflectivity plate to detach upon impact, enhancing accident behavior and safety.

Abstract

Retroreflective device (5) for a motor vehicle (1), characterized by: - a first reflector (10) comprising a colored first cover plate (11) which is provided with a specifically manufactured retroreflective optic (13) by means of which a first quantity of light (8) directed onto the retroreflective device (5) can be selectively reflected into a retroreflective area (14); and - a second reflector (15) formed separately from and arranged next to the first reflector (10), which comprises a second cover plate (16) having the same color as the first cover plate (11), formed separately from and directly adjacent to the first cover plate (11), which: o is equipped with a specifically manufactured retroreflective optic by means of which a second quantity of the light (8) emitted onto the retroreflective device (5), which is smaller than the first quantity, can be selectively reflected into the retroreflective area (14) or reflection of the light (8) emitted onto the retroreflective device (5) into the retroreflective area (14) is prevented; or ◯ free from a specifically manufactured retroreflective optic for the targeted reflection of light.
