Abstract
An improved accelerometer of the type that comprises a paddle (30), a support (32), and suspension means (34) for suspending the paddle from the support, such that the paddle can move along a sensing axis. The support includes an unclamped portion (42) to which the suspension means is attached, and a clamped portion (40) through which the support is mounted. The invention provides restraining means (72, 100, 120, 132, 134, 176, 196, 206) separate from the clamped portion of the support, for limiting the travel of the unclamped portion in directions normal to the sensing axis, for example, along the hinge axis. The result is an accelerometer able to withstand higher cross axis shocks without failure.
