HEADLINER FOR VEHICLE FOR REDUCING HEAD INJURY OF BACKSEAT OCCUPANT

摘要

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.
