ABSTRACT:
A pendulum inertia sensor assembly for self-aligning the pendulum weight body in response to forward or rearward tilting of the retractor frame. A pendulum saddle is provided having an annular pendulum hanging surface which is inclined from a horizontal orientation. The pendulum head is cocked on the pendulum neck so that the saddle seating surface on the pendulum head seats entirely on the pendulum hanging surface while the pendulum weight body is suspended vertically below. As the retractor frame and pendulum saddle are tilted forward or rearward, the pendulum head rotates seatingly about the pendulum hanging surface as the pendulum weight is moved to its new vertical position. The saddle contact surface on the pendulum head and pendulum hanging surface on the saddle are made from low friction materials to allow low resistance rotation of the pendulum head during automatic adjustment and realigning of the pendulum body during retractor frame tilting.
