Abstract
A freely-flexing cantilever-type inertial sensor is suspended from one end so that its other end may move in response to inertial forces, for example, as a result of braking in a towing vehicle. The pendulum blade is secured to a rigid support structure in a manner whereby the opposite sides of the pendulum, which is preferably of multiple-layer construction and is elastically-deformable, may freely shift longitudinally with respect to one another upon lateral flexure of the pendulum in response to inertial forces. Preferably, this is accomplished by utilizing an adhesive connection directly between the rigid support and the adjacent side of the pendulum, whereby only that layer closest to the support is directly secured to it. The support for the pendulum preferably includes a self-hinge by which the position of the pendulum-supporting portion may be changed with respect to that of a base portion, in order to current for non-verticality in the actual operating environment. The base preferably provides integral mounts for optical components which monitor the inertially-induced pendulum flexure, and the optical axis is preferably coincident with the pivot axis of the self-hinge.
