Abstract: The present invention provides an A-pillar bracket for vehicles with improved wiring assembly capable of being used for general purposes, by installing a pair of rotating pieces formed to rotate facing each other on two supports formed to face each other so that each rotating piece is rotatable in place, where each of the rotating pieces is configured to adjust a rotation angle twice by forcibly rotating with respect to the support, thereby stably supporting and fixing wiring even when the thickness of the wiring fixed and supported by the A-pillar bracket becomes thicker. In particular, the present invention provides an A-pillar bracket for vehicles with improved wiring assembly capable of more stably supporting and fixing wiring even when the thickness of the wiring changes by forming a pressing protrusion on at least one of two rotating pieces and configuring a portion wrapping the wiring in an arc shape.

Abstract: By forming hooks on a sunroof bracket to allow a headliner portion wrapping an opening to be fixedly caught thereon, it is possible to prevent a portion subjected to a wrapping process from being easily peeled or detached, thereby improving the quality of the headliner. In particular, by forming the hooks one-to-one on at least corner portions of the opening to allow portions on which it is difficult to perform the wrapping process due to the occurrence of overlapping when the wrapping process is performed and which are easily peeled or separated even after the process to be caught thereon, it is possible to further improve the quality of the headliner.

Abstract: When a non-woven fabric is attached to a surface of a polyurethane foam sheet, an aluminum film is inserted between and integrally formed with the non-woven fabric and polyurethane foam sheet so that an increase in weight of a headliner is minimized, and a temperature of a vehicle interior is lowered by about 1.6° C. as compared to a case of attaching a non-woven fabric using a hot melt film through a heat insulating function of the headliner, thereby providing a comfortable internal environment. In particular, the aluminum film coated with an adhesive is used to easily integrally attach the polyurethane foam sheet and the non-woven fabric to manufacture the headliner and lower the temperature of the vehicle interior through the heat insulating function. In addition, the aluminum film is attached to both surfaces of the polyurethane foam sheet and integrally manufactured with the polyurethane foam sheet so that a heat insulating effect is achieved twice, and thereby effectively insulating heat being transferred to the vehicle interior so as to form a comfortable internal environment.

Abstract: In the present invention, a laser pointer is mounted on an upper mold and formed to mark a position of an auxiliary raw material disposed on a raw material disposed on a lower mold so that everyone can easily accurately arrange the auxiliary raw material at a predetermined position and molds the auxiliary raw material to improve a molding efficiency. In particular, in the present invention, the laser pointer is formed to mark vertex positions of the auxiliary raw material so that an operator can arrange vertexes of the auxiliary raw material at the predetermined position to quickly arrange the auxiliary raw material at the predetermined position and accurately mold the auxiliary raw material. In this case, in the present invention, at least two laser points are mounted along an edge of the upper mold to mark vertices of the auxiliary raw material so that the auxiliary raw material can be more quickly accurately disposed at the predetermined position and integrally molded.

Abstract: A wiper blade having a plurality of check holes consecutively formed to pass through portions of a blade in contact with a windshield surface, allows a driver to clearly see a non-wiping portion on the windshield surface as the portions in contact with the windshield surface are worn out and the check holes are open and easily recognize a replacement timing. Mounting a conductive rubber band or a tensile force sensor on the portions of the blade, allows to easily detect a degree of the wear of a blade and, particularly, by changing conductivity or a tensile force as the check holes are open, allows to more easily check the replacement timing. Visually or audibly notifying the driver of the replacement timing according to a detected signal related to the replacement timing, allows the driver to perform safe driving in quick response to the detected signal.

Abstract: A headlining having a heat shielding function for a vehicle and a manufacturing method for producing the headlining, where a complex layer formed of glass fiber and polypropylene is manufactured among various layers forming the headlining having a multilayered structure, and a hot melt film containing a heat shielding material is further provided on at least one of both surfaces of the complex layer to shield heat by the headlining. In so doing, the headlining is capable of reducing an internal temperature of the vehicle even in the summertime, and thus an operation time of an air conditioner is reduced, and fuel efficiency of the vehicle is increased. The headlining also has a heat shielding function for a vehicle, in which carbon nanotubes as the heat shielding material are used to provide the heat shielding and weight lighting effects and also to simultaneously improve the fuel efficiency of the vehicle.
