Abstract
According to an inner panel for vehicles of the present invention, a bead forming surface is so provided as to extend continuously with an upper edge part of a wall rising from a bottom surface of the inner panel. Upper beads and lower beads are formed on the bead forming surface. The upper and lower beads extend in a longitudinal direction of a vehicle and are arranged alternately in a width direction of the vehicle. The bead forming surface is positioned above a middle position between an upper surface of the upper bead and a lower surface of the lower bead. Further, the bead forming surface is positioned lower than the upper surface of the upper bead by 3 mm or more. With this structure, a sufficient first acceleration wave can be secured by expanding a stress propagation range in a direction perpendicular to the length of the beads with respect to the first acceleration wave and, also, by reducing a local deformation to be caused by a deformation load from the above of the vehicle during a head impact. Further, with respect to a load from below of the vehicle when contacting built-in components, the inner panel is easily crushed, which can lower a second acceleration wave.
