From the brochure "Side Impact Structures", published on January 13, 1969 by SAE ₁ USA, it is already known to arrange so-called Hamm beams in the vehicle doors horizontally to the vehicle floor. These Hammbalken are hollow and have longitudinal ribs to stiffen the doors in their horizontal extent. The Ramnbalken are rigidly connected to the door frame in the door. The door hinge and door lock elements are reinforced and attached to reinforcements of the door and the door pillars.

_. In the event of a lateral impact by another vehicle or by an object against which the endangered vehicle is thrown, the endangered vehicle is steered away from the other vehicle or from the object, deforming the ram beam. On the door pillars are exerted on door hinges and catch very large tensile forces by shortening the ^s bumper bar.

The manufacture and attachment of the comb beams in the vehicle doors as well as the Door hinge, door lock and body reinforcements are relatively expensive. Conventional door hinges and locks are less strong unsuitable, as the ram beam is only fully effective when ™ it is ensured that the door of the endangered vehicle from one or from both door pillars is not torn loose, with the result that the door without large Resistance is pressed into the passenger compartment. It is also disadvantageous that the ramming beam only has active connections to the door pillars, as this the tensile forces transmitted through the ram beam only from small areas Karoseerie areas must be included, so that the stress of the Body areas concerned can be so large that the door or the door can be torn away even the door pillars becomes possible. In these cases, the protective effect of the

OWQINAL INSPECTED Ramming bar only guaranteed to a limited extent.

In addition, the ram beam can only be connected to the door pillars sohon "can lead to irreparable body damage in the event of side impacts of less strength.

The invention is therefore based on the object of providing a device sum protection of the occupants of motor vehicles, in which the disadvantages of the known ram bars are eliminated, a more effective protection for the occupants is guaranteed, and which can be produced simply and economically using existing door and body elements.

According to the invention, this object is achieved in that an additional component emerges from the side of the door and in adjacent body parts and / or is anchored in the door pillars, the additional component firmly anchored on the hinge side of the door in the body parts and / or the door pillars

in and for anchoring the additional component parts and / or

a coupling device is provided for the door pillars on the sole plate side

By anchoring the additional component in parts of the body side wall and the door pillars, door hinges and locks are bridged when the door is closed. (

Another feature of the invention is that there are several additional ones in each door ISO parts provided

As a result, the size of the protective effect of the additional components is practically nonexistent Qrense set. Bs can be done without significantly higher additional costs and without significant increase in vehicle weight several additional components related because the necessary reinforcement elements are already available when using an additional component.
