Patent DE-3634128-A1 (DE)
IPC: E06B9/17
Filed: 1986-10-07
Abstract: 1. Assembly of a frame provided with roller shutter guiding devices and having an associated blind box 2.1. If frames (11) with roller shutter guiding devices (114, 116) are already provided with the blind box (31) in the manufacturing operation, transport to the site of installation proves problematic. Putting together the frame (11) and the blind box (31) at the site of installation in a conventional manner is at least time-consuming, especially since the blind box (31) cannot be mounted as a whole. 2.2. Assembly of the frame (11) with roller shutter guiding devices (114, 116) is facilitated in that the bottom board (311) of the blind box (31) is joined directly or indirectly with the upper frame piece (213) of the frame (11) by means of coupling elements (211, 312) which extend at the front over the region between the roller shutter guiding devices (114, 116) and, at a distance therefrom, over the length of the upper frame piece (116). 2.3.

Title: Bumper for a motor vehicle
Inventor: HOEFS RAINER DIPL ING
IPC: B60R19/18
Filed: 1986-10-23
Abstract: A bumper for a motor vehicle includes a first supporting part which is fastened to the body, a second supporting part which is mounted in front and extends at a distance from the first support part, and an energy-absorbing body which is made of a regenerable foamed material and is arranged between the two supporting parts. The two supporting parts are, by means of locally mounted holding elements which are arranged so as to be vertically offset with respect to one another, connected to one another in such a way that in the event of a collision, the second supporting part executes a horizontal displacement movement in the longitudinal and/or transverse direction of the vehicle. In order to be able to take up the energy occurring in the event of a collision in a reliable fashion even when the space for construction in the longitudinal direction of the vehicle is locally limited, the two supporting parts are only connected to one another by means of the elastic holding elements, in such a way that in the event of a collision, the second supporting part in addition executes a tipping movement in the direction of the vertical axis of the vehicle. The body made of foamed material has regions which are arranged one on top of the other in a vertical direction and have different longitudinal extents and/or different deformation paths in the longitudinal direction of the vehicle.
