  • Patent number: 12496950
    Abstract: By separating a middle portion of a handle body to be divided into an adjustment part and support parts formed at both sides of the adjustment part and allowing the adjustment part to be connected to the support parts with extension members, it allows the extension members to get out of the support parts when only the adjustment part is gripped and pulled down to allow the adjustment part to move down so that an occupant with a small sitting height can also conveniently use the assist handle. In particular, by allowing the extension members to be integrally formed with the adjustment part at both ends of the adjustment part, when the adjustment part is formed, it is possible to easily manufacture the assist handle without undergoing a separate manufacturing process so that an occupant can conveniently use the assist handle by conveniently adjusting a height of the assist handle.

  • Publication number: 20210094482
    Abstract: Since a rear edge of a headliner is set as a daylight opening (DLO) uppermost endpoint, a rear header point (RHP) is pushed backward from an existing position. Accordingly, since a space in which a jaw is rotatable when an occupant of a backseat collides with the headliner is secured, a Head Injury Criterion value is decreased such that a level of a head injury may be reduced. Particularly, when a distance between the DLO uppermost endpoint and the RHP is greater than or equal to 112 mm, the RHP is set a point 112 mm from the DLO uppermost endpoint, setting an angle between an XY-plane passing the DLO uppermost endpoint and the RHP to be present within a range of 0.5 to 10°, or setting a height difference in a Z-axis direction from the XY-plane as being in a range of 1 to 10 mm.

  • 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.

  • Patent number: 9187048
    Abstract: A method of mounting a cable on a headliner and a headliner used therefor, that are capable of simplifying an attachment process by attaching the cable to the headliner using an attaching cloth, and preventing the attached cable from being easily separated from the headliner and securely fixing the cable to reduce generation of noises. The method is capable of easily recognizing a cable mounting position and arbitrarily adjusting the cable mounting position to a width of an attaching cloth. A worker may easily perform an assembly process by attaching the cable using the attaching cloth, separating an incorrectly attached cable and then attaching the cable thereto again. The attaching cloth may be at a mounting position of a headliner opposite to a roof panel and at which a cable is mounted, and at an outer circumferential surface of the cable, respectively.
