Optical block for motor vehicle, has casing comprising rigid lower part, and deformable zone comprising upper wall of casing, where zone is deformed when zone is subjected to stress equivalent to stress generated by pedestrian impact

摘要

#CMT# #/CMT# The block has an optical casing (18) comprising a rigid lower part (40), and a deformable zone (36) comprising an upper wall (19b) of the casing. The zone is deformed when the zone is subjected to a stress equivalent to a stress generated by a pedestrian impact. The upper wall is made of flexible material, and has a thickness lesser than that of the lower part. A mobile optical module (22) has a high power light source (24) e.g. headlight lamp, and a support (28) comprising a position adjusting unit (30) to adjust position of the light source, where the module is connected to the lower part. #CMT#USE : #/CMT# Optical block for a motor vehicle for protecting a pedestrian against impact. #CMT#ADVANTAGE : #/CMT# The deformable zone considers the treatment of hip impact and head impact for ensuring better safety to the pedestrian during the impact, irrespective of the dimensions of the optical block, while guaranteeing better maintenance of the block on the vehicle. The upper wall allows easy reparation of the optical block after the impact, and avoids the need to change the casing. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of an optical block. 18 : Optical casing 19b : Upper wall 22 : Mobile optical module 24 : High power light source 28 : Support 30 : Position adjusting unit 36 : Deformable zone 40 : Rigid lower part.
