An impact absorbing outer body structure of a motor vehicle including an outer panel with a deformable impact region. For the protection of a person or object making impact on the outer-panel, the deformable impact region can be displaced outwardly toward said person or object. The outer panel is provided with at least one plastically deformable impact region which is weakened in relation to the rest of the outer panel, and a supporting shell is firmly connected to the outer panel on an inner side. The supporting shell has at least the stability of the rest of the outer panel, enclosing the impact region and forming, along with the outer panel, a closed cavity. In the event of an impact load, the plastically deformable impact region can be expanded rapidly outward by means of a high-pressure charge, such as a pyrotechnical propellant charge, to provide a deformation area to absorb the energy of the impact. The impact absorbing structure is particularly used in hoods and doors of motor vehicles.

[ What is claimed is:] [1.] An impact absorbing outer body structure of a motor vehicle, comprising:an outer motor vehicle body panel having at least one plastically deformable impact region;a supporting shell fixed to an inner side of the outer motor vehicle body panel such that a closed cavity is defined between the supporting shell and the impact region; anda high pressure charge which is dischargeable into said closed cavity in response to an impact load in order to deform said impact region of the outer motor vehicle body panel outwardly.
