Abstract

Impact intrusion barrier device for a vehicle door of the type which includes spaced inner, outer and side door panels defining a door cavity therebetween, and which is movably connected between forward and rear door pillar members. The device includes a beam member positioned in the door cavity and adapted to extend between the pillar members. The beam member is curved outwardly along a longitudinal axis thereof and has a pair of beam end portions which are operable to move longitudinally away from one another on adjacent outwardly facing surfaces of the side door panels or the pillar members when an inward force is applied to the beam member until the end portions contact abutment surfaces on the side door panels or the pillar members, thereby absorbing energy therefrom and initially directing the force laterally away from the interior of the vehicle and into the pillar members either directly or through the side door panels. The beam member preferably includes an outer panel member and an inner panel member which are both curved outwardly along a longitudinal axis thereof. The inner panel member is positioned substantially directly behind and spaced from the outer panel member, and the inner and outer panel members have end portions which are secured together to define the beam end portions.
