ABSTRACT:
The invention relates to a bumper comprising a bearing member and an elastic deformable plastic element provided with an impact surface, which element substantially consists of a number of interconnected box-shaped formations, the cross sections of which are regular polygons having an even number of sides and the center lines of which are parallel to the impact surface in which near the midpoints of two opposite sides the box-shaped formations are connected with each other and with the impact surface by connecting webs extending lengthwise along the box-shaped formations perpendicular to the impact surface and to the said sides. The choice of the locations for the interconnecting webs results in a relatively high elastic deformation of the element.
