Active hood or bonnet protecting individual during collision with vehicle, has mechanisms causing upward bodily rotation about virtual center ahead of bonnet

摘要

In an impending collision, the bonnet (10) as a whole is lifted from a closed- to a raised position. Two displacement mechanisms (18, 20, 22; 26) are used. They are designed to rotate the bonnet slightly during displacement, about a virtual center (28) ahead of the bonnet front end (30). The rear mechanism (26) is a hinge device, the front mechanism (18, 20, 22) forms a four bar linkage. Each permits displacement relative to the bodywork (14). The actuator (24) includes e.g. a spring- or pyrotechnic component.
