Problems solved by technology

[0005] However, this measure has not been implemented in terms of under-hood areas and pedestrian impacts due to packaging issues arising from the crowded space under the hood and more importantly because analytical simulations have shown that filling the empty under-hood areas is ineffective in mitigating the consequences of pedestrian impacts

Embodiment Construction

[0040] The following description of the preferred embodiments is merely exemplary in nature and in no way intended to limit the invention, its application or uses. Such as Figure 2-4 As shown, the present invention relates to an energy absorbing system 10 suitable for use within a vehicle 12 . In a first aspect, the system 10 is more specifically adapted to absorb kinetic energy from a projectile 14 (eg, a pedestrian's head, etc.) having a projectile path or trajectory directed toward an exterior surface 16 of the vehicle 12 . It should be understood that projectile 14 may comprise non-biological organisms.

[0041] The exterior surface 16 of primary concern is defined by the hood 18 of the vehicle 12 such that the system 10 is particularly suited for mitigating pedestrian impact events. However, the benefits and advantages of using the system 10 with other applications (eg, with respect to boats) and in conjunction with other vehicle components are certainly within the sco...

Abstract

A system for and method of mitigating pedestrian impact utilizing an energy absorption member, such as an expandable honeycomb celled matrix, and at least one tether disposed within a recessed formation defined by the vehicle and interconnected to the member and a drive mechanism, wherein the member is selectively caused to extend and be spaced from an exterior surface.

Description

technical field [0001] The present invention relates generally to active energy absorbing systems and methods of use; and more particularly to selectively variable systems / assemblies that use cords disposed within recessed structures to actuate energy absorbing members such as expandable honeycomb matrices, And a method of absorbing energy by projecting members from the protective surface to intercept the path of the ejection prior to engaging the surface. Background technique [0002] Mitigation of the frequency and consequences of pedestrian collisions becomes an issue, especially as vehicles navigate urban arterials and roadways. In the event of a frontal collision with a pedestrian, the upper torso and head of the pedestrian rotate sufficiently to strike the hood and deform it sufficiently to contact the underlying structure near the hood. in prior art figure 1 An analytical simulation of the forces / accelerations that would occur before, during, and after a pedestrian'...
