A MOTOR VEHICLE LIGHT WITH A SEALING RING BETWEEN A CASING AND ADJUSTABLE REFLECTOR

摘要

A seal (3) for sealing a gap between a casing (1) of a motor vehicle and a reflector (2) placed therein is proposed according to the invention. Said reflector (2) is furnished with at least one smooth outer sealing surface (23), and at least one smooth inner sealing surface (14) is foreseen within the casing (1). The uniform seal (3) on the one hand comprises at least approximately tubular stationary sealing portion (31), which is intended to be rest on said outer sealing surface (23) of the reflector (2), and on the other hand as well as a dynamic sealing portion (32), namely a sleeve comprising a slightly convex outer sealing surface (321) and being pressed towards the inner sealing surface (14) of the casing (1). Said seal (3) moreover comprises a weak portion (33) in the form of a circumferentially extending recess, which is located on the one axial end area (310') of the stationary sealing portion (31) between the last and the dynamic sealing portion (32), and which moreover extends axially with respect to the stationary sealing portion (31) and is opened towards the outer sealing surface (321) of the dynamic sealing portion (32). Said stationary sealing portion (31) of the seal (3) is secured against any movement in one or another direction along the optical axis (20) of the reflector (2).
