An inertial sensor of the type having an inertially responsive pendulum and a rigid support structure for operatively supporting the pendulum, includes an improved pendulum attitude adjustment assembly which allows precise adjustment of the verticality of the pendulum. The rigid support structure includes a base portion and a pendulum mount portion which is pivotally attached to the base portion. The base is secured at a fixed location and at a fixed attitude relative to the housing. The pendulum is attached at one end to the pendulum mount portion and another end of the pendulum is free to move in response to inertial forces. The attitude adjustment assembly includes an adjustment shaft which is operably coupled to the pendulum mount portion to achieve rotation of the pendulum mount portion with respect to the base portion through a first angle when the adjustment shaft is rotated through an angle greater than the first angle. The pendulum mount portion is preferably rotatable with respect to the base portion through an angle in excess of ninety degrees, and the adjustment shaft has a threaded coupling arrangement which preferably requires rotation of the shaft through a number of degrees in order to rotate the pendulum mount portion a single degree relative to the base portion, thereby providing a desirably high order of resolution while also achieving ease and convenience of operation. |
