Abstract: A high stiffness waterproof roof panel pad for a vehicle, which is configured by stacking and laminating a waterproof reinforcing layer coated with PE layers on both surfaces of a urethane foam pad, thereby reinforcing the stiffness of a vehicle body panel, preventing the pad from becoming wet due to dew condensation and thus increasing noise and vibration reduction effects and having a waterproof function. Additionally, a method of manufacturing the waterproof roof panel pad includes preparing a hard urethane foam pad, preparing a waterproof reinforcing layer of which both surfaces are coated with PE layers, stacking the waterproof reinforcing layer on both surfaces of the urethane foam pad, laminating the PE layer in contact with the urethane foam pad and integrally forming the urethane foam pad and the waterproof reinforcing layer, and performing a cutting operation according to a shape and a size of a roof panel.

Abstract: A camera and a black box for a vehicle are accommodated in the headliner to minimally expose the black box to the inside of the vehicle, preventing robbery of or damage to the black box and not spoiling the interior design of the vehicle. A headliner is integrated with four cameras installed at corners of the headliner to photograph required videos in front and rear, and both sides of the vehicle, obtaining videos of surroundings of the vehicle. In addition, provided is a headliner integrated with a camera of a black box for a vehicle capable of photographing videos of surroundings of the vehicle and the inside thereof using the camera of the black box and thus simultaneously obtaining a basic function of the black box and a function of observing the inside of the vehicle. The black box is installed at the headliner.

Abstract: Provided is an impact-absorbing auxiliary material for a vehicle, which is fabricated using pulp so that a mold may be easily fabricated without regard to a shape of the auxiliary material for absorbing the impact, and moreover, which is environmentally friendly and does not generate a waste treatment problem when being discarded. Also provided is an impact-absorbing auxiliary material of a vehicle, which is capable of obtaining a sufficient impact-absorbing performance required in the impact-absorbing auxiliary material through continuous deformation of ridges and ribs by connecting ribs between hollow ridge portions and forming integrally. The auxiliary material includes a base fabricated using pulp, wherein hollow ridges integrally protrude from the base in a plurality of rows at predetermined intervals, and the ridges adjacent to each other are connected to each other through ribs.
