Abstract: A hinge device is provided comprising a first member (12) pivotally connected about a hinge axis (14) to a second member (16), an implement to permit radial movement of the hinge axis (14) upon the application of a force to the members, and a locking assembly on at least one of the members to enable inter-engagement of the members to prevent pivotal movement therebetween when the force is applied. The locking assembly is provided by a projection (30) formed in one member and engageable in the other member. The hinge device is particularly of use in attaching a hood along its rear edge to a car body, in which one member is attached to the hood and the other member is attached to the car body.
