The present invention relates to a cowl top pad formed by having a sound absorption member and a sound insulation member integrally attached thereon, wherein an extension part formed by extending only the sound absorption member is brought into contact with a windshield to remove a gap therebetween, and, as a result, even if the windshield is deformed by wind pressure or vibrations exerted during driving, the extension part formed of the sound absorption member can stably support the windshield to prevent damage thereto while blocking noise from flowing into the gap between the windshield and the cowl top pad, which can lead to an improvement in noise performance. Here, at least one solenoid valve is mounted on a cowl top panel on which the cowl top pad is mounted, and the solenoid valve receiving a signal from a sensor detecting the closure of a vehicle door presses the extension part to form a gap between the windshield and the cowl top pad, thereby quickly discharging high pressure in the interior of the vehicle.

    본 발명은 흡음재와 그 위에 차음재가 일체로 부착되어 이루어진 카울 탑 패드에서, 상기 흡음재만 연장하여 이루어진 연장 부분이 윈드 실드와 맞닿게 하여 그 사이의 틈새를 없앨 수 있게 구성함으로써, 주행 중 받는 풍압이나 진동 등으로 윈드 실드가 변형되더라도 흡음재로 이루어진 연장 부분이 안정적으로 지지하여 파손되지 않게 하면서도 윈드 실드와 카울 탑 패드 사이로 소음이 유입하는 것을 차단하여 소음 성능을 개선할 수 있다. 이때, 카울 탑 패드가 장착되는 카울 탑 패널에는 적어도 하나의 솔레노이드밸브를 장착하고, 자동차 문이 닫히는 것을 검출한 센서의 신호를 받은 이 솔레노이드가 연장 부분을 압착하여 윈드 실드와 카울 탑 패드 사이에 틈새를 형성함으로, 자동차 실내의 높아진 압력을 신속하게 배출할 수 있다.
