  • Pad with speaker retention bracket
    Patent number: 11958415
    Abstract: A vehicle seat is provided with a seat pad formed of a foam material defining a seating surface for supporting an occupant and a rear surface opposite the seating surface. A speaker cavity for receiving a speaker assembly is formed in the pad and extends from the rear surface toward the seating surface. At least one speaker retention bracket is disposed in the speaker cavity. The retention bracket is co-molded with the pad so at least a portion of the retention bracket is encapsulated in foam material to retain the bracket in the cavity, the retention bracket having at least one retention feature extending within the cavity to cooperate with the speaker assembly and retain the speaker assembly in the pad. The speaker retention bracket is configured to mount a speaker assembly within the cavity to allow acoustic radiation to be transmitted through the foam material to a seated occupant.
