BAFFLE AND REINFORCEMENT ASSEMBLY

摘要

A combined baffle and reinforcing assembly (16) is provided for use within t he cavity of a structural member (12, 14) to dampen acoustic transmissions through the cavity and provide reinforcement in a direction transverse to th e longitudinal axis of the structural member (12, 14). The assembly (16) includes a synthetic carrier which includes an interior area, marginal rim, and an attachment member preferably in the form of a clip for insertion to t he corresponding hole in the wall of the structural member, and a circumscribin g and continuous band of reinforcing material extending around the periphery o f the carrier. The assembly (16) may be economically manufactured by co- injection molding or insert molding of the thermally expansible material around the carrier. The marginal rim of the carrier may include base wall an d a support flange for receiving the thermally expansible material thereon.
