Abstract

An exhaust gas tailpipe assembly for an exhaust gas system of a motor vehicle, having at least one exhaust gas tailpipe, which is annularly surrounded by a tailpipe aperture assembly at an end facing away from the exhaust gas system. The tailpipe aperture assembly is at least partially fixedly connected to a body part of the motor vehicle and includes at least one aperture part, such that the tailpipe aperture assembly can be slid, when viewed longitudinally, onto the exhaust gas tailpipe in a crash event. The exhaust gas tailpipe is configured so as to be curved with at least two exhaust gas tailpipe parts, wherein a longitudinal axis of a second exhaust gas tailpipe part extends at an angle to a longitudinal axis of a first exhaust gas tailpipe part. The aperture part includes at least one deformation region in a circumferential region facing the exhaust gas tailpipe.

Dependent claims

An exhaust gas tailpipe assembly for an exhaust gas system of a motor vehicle, said exhaust gas tailpipe assembly comprising:

at least one exhaust gas tailpipe,
a tailpipe aperture assembly annularly surrounding the exhaust gas tailpipe at an end of the exhaust gas tailpipe that faces away from the exhaust gas system, wherein the tailpipe aperture assembly is configured to be at least partially fixedly connected to a body part of the motor vehicle and comprises at least one aperture part such that the tailpipe aperture assembly can slide, when viewed longitudinally, onto the exhaust gas tailpipe in a crash event,
wherein the exhaust gas tailpipe is curved and has at least two exhaust gas tailpipe parts, wherein a longitudinal axis of a second exhaust gas tailpipe part extends at an angle a, which measures from 90° to 160°, to a longitudinal axis of a first exhaust gas tailpipe part in a region of the tailpipe aperture assembly, and
wherein the at least one aperture part comprises at least one deformation region in a circumferential region facing the exhaust gas tailpipe.
