ABSTRACT:
An accelerometer for measuring the acceleration of a body in the direction of a reference axis includes a support member, mountable on the body, and a magnet arrangement mounted on the support member which defines an air gap between pole surfaces extending generally parallel to the reference axis. The magnet provides magnetic flux across the air gap which coacts with a magnetic field produced an electromagnetic coil assembly mounted on a movable member. The movable member is mounted on the support member by a hinge which includes a piece of polymer film permitting the movable member to pivot with respect to the support member about a pivot axis generally perpendicular to the reference axis. The polymer film is molded into portions of the movable member and the support member.
