AI Technical Summary

Technical Problem

Existing support arrangements for motor vehicle front hoods do not adequately address passive pedestrian and cyclist protection, particularly when the hood sinks into the engine compartment during collisions, potentially causing injuries.

Method used

A support arrangement with a buffer element that breaks under excessive load, allowing the limiting stop to pass through a passage opening, enabling the front hood to sink further into the vehicle body, thereby reducing the risk of injury.

Benefits of technology

Enhances passive protection by allowing controlled sinking of the front hood into the vehicle body during collisions, minimizing the risk of injury to pedestrians and cyclists.

Abstract

Support arrangement (1) for supporting a front hood (2) pivotally attached to the body of a motor vehicle, which is designed to open and close an opening in the body, comprising: - at least one limit stop (4) attached to a load-bearing and / or load-distributing structural element (3) of the body, and - at least one support means (5) attached to an underside of the front hood (2) and designed such that, in a closed position of the front hood (2) in which it can close the opening in the body, it can be supported sectionally by the limit stop (4), wherein the limit stop (4) is designed to limit the sinking of at least a part of the front hood (2) into the opening in the body, and wherein a buffer element (6) is attached to the support means (5) or to the limit stop (4), which is designed such that, when a load is applied,which is greater than a limit load, breaks at least partially, so that at least part of the hood (2) can sink further into the opening of the body, characterized in that the support means (5) has a passage opening (51) which is aligned in the axial direction with the limit stop (4) such that the limit stop (4) can pass through the passage opening (51) at least section by section in the event of a breakage of the buffer element (6).
