Vehicle interior material

1. Field of the Invention A vehicle interior material is provided that efficiently dampens impact forces with ribs protruding into a limited space enclosed by a vehicle panel and a facer, and that reduces the protrusion height of the ribs, thereby curbing the amount that the vehicle interior material bulges into the space of the vehicle interior. The vehicle interior material includes a facer () with a substantially C-shaped cross-section covering a panel ridge () extending in a longitudinal direction on the vehicle compartment side of a vehicle panel, a space () being provided between the panel ridge and the facer; and a plurality of plate-shaped ribs () which are arranged independently from one another, bridging side walls of the facer, the ribs protruding from a rear face of the facer () opposite the vehicle panel into the space () and arranged at substantially right angles with the longitudinal direction of the vehicle panel. The shape of a protruding edge of the plate-shaped ribs () substantially follows at least a protrusion end face of the panel ridge () and the passenger-opposing lateral face formed in continuation thereof to one side. The vehicle interior material further includes a deformation-inducing means () causing a rib portion (B) protruding towards the protrusion end face of the panel ridge () to buckle at an intermediate protrusion position when subjected to an impact by a passenger.
