Abstract

A vehicle heater combustion chamber assembly includes a housing area (14) with an ignition element mount (36) supporting an ignition element (34) and another housing area (16) defining a fluid flow space (26) with an access opening (32). The ignition element or/and an electric ignition element line (76) is moveable through the access opening. An elastically deformable closing element (40) closes the access opening and includes a meshing area (48), interacting with a housing area wall (42) surrounding the ignition element access opening and including an inner meshing area supported relative to an inner surface of the wall, which faces the fluid flow space. The closing element includes a closing element bottom (44) with an outer bottom surface (94) oriented outwardly, in the direction away from the fluid flow space. The outer bottom surface is offset in a direction of a closing element longitudinal axis towards the fluid flow space.
