Abstract
A bumper for a front end of a vehicle includes a body having an opening defining an air flow inlet. The opening is elongated in the transverse direction of the body and is defined by spaced apart transverse walls and spaced apart side walls. A grille is disposed in the opening. The grille includes at least one generally horizontal member having at least one sound attenuating member attached thereto and configured to at least partially alter the air flow passing through the grille to mitigate resonance associated with the flow of air through the grill.
Claims16
A bumper for a front end of a vehicle comprising:
- a body having an opening defining an air flow inlet, the opening being elongated in the transverse direction of the body, the opening defined by spaced apart transverse walls and spaced apart side walls;
- and
- a grille disposed in the opening, the grille including at least one generally horizontal member having at least one sound attenuating member attached thereto,
- wherein the grille includes at least two spaced apart, immediately adjacent vertical members which are inclined relative to the horizontal members, and the at least one sound attenuating member is positioned entirely between the spaced immediately adjacent vertical members, the at least one sound attenuating member has spaced apart sidewalls, one of the sound attenuating member sidewalls extending parallel to one of the vertical members and the other sound attenuating member sidewall extending parallel to the other vertical member.
A grille for a bumper for a front end of a vehicle comprising:
- a plurality of generally horizontal members connected with a plurality of generally vertical members, the plurality of horizontal members and vertical members defining a plurality of air ports through which air passes through the grille, and at least one sound attenuating member provided between immediately adjacent vertical members and entirely in an air port, the at least one sound attenuating member connected with one of the horizontal members and spaced from the other horizontal member and the immediately adjacent vertical members that define the air port.
