US Patent 11247611 Vehicle door mirror assembly

An external mirror assembly for a vehicle includes a support arm adapted to be affixed to an associated vehicle side door, and a housing movably mounted to the support arm. A glass assembly is secured to the housing. A flexible defector is mounted to the housing and surrounding a portion of the support arm received in the housing. The deflector has a stepped configuration allowing for stretching of the deflector as the housing is moved relative to the support arm and to reduce wind noise through a gap between the support arm portion and the housing.
