  • Patent number: 10434958
    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.

  • Publication number: 20180022070
    Abstract: A vehicle headliner material includes a stiffening layer for reinforcing each side of a thermoplastic resin layer so that the material satisfies required bending stiffness while having lighter weight and thus can prevent safety accidents that may occur due to increasing of headliner material weight. In particular, by using a glass mat, with a thermoplastic resin sheet on each side thereof, that constitutes a part of each stiffening layer to reinforce structural stiffness of the material, the vehicle headliner material has improved formability, improved flexural strength, and direct adhesion without an additional adhesive or the like. Also, by not using polyurethane foam to prepare the vehicle headliner material, problems such as generation of dust derived from processing polyurethane foam into sheets can be eliminated, and safe and pleasant working environments can be provided for workers.

  • Publication number: 20180022075
    Abstract: A vehicle headliner material includes a stiffening layer to prevent moisture penetration by reinforcing each side of a natural fiber layer. In this way, the natural fibers can be prevented from holding moisture, and thus safety accidents that may be caused by increased weight of a headliner material or a headliner being permanently deformed due to the headliner material that repeats holding and releasing moisture can be prevented. The vehicle headliner material is provided with improved formability, improved flexural strength, enhanced structural stiffness, and direct adhesion without an additional adhesive by including a synthetic resin in the natural fiber layer along with natural fibers and using a glass mat and thermoplastic resin sheets as constituent materials of each stiffening layer.

  • Patent number: 9487067
    Abstract: A fixture for a vehicle, which is configured so that a plurality of retaining arms inserted into and caught by a coupling hole formed in a body panel are located on an imaginary circle, and arranged in the form of a cone so as to absorb an external force, thereby being easily assembled, and which is capable of dispersing and absorbing twisting generated when an indoor handle installed using the fixture is used. In the fixture for the vehicle, even-numbered retaining arms are formed to face each other on the imaginary circle, such that an external force generated when the indoor handle is used is dispersed and absorbed regardless of an applied direction of the external force, and a separation or an escape of the fixture is prevented, and thus a noise and a safety accident are reduced.
