Abstract
An adjustable energy absorption device whose setting can be rendered tamper-proof, and a method of rendering the setting of an adjustable energy absorption device tamper-proof. The device is of the type that includes an outer cylinder and an adjustment member extending from one end thereof, the rotational position of the adjustment member determining the resisting force setting of the device. A frangible portion connects a first end portion of the adjustment member to a second end portion thereof, the first end portion being freely accessible from outside the outer cylinder, and the second end portion being retained within the outer cylinder. The resisting force setting of the device is adjusted to a predetermined setting by gripping the first end portion and rotating the adjustment member. The first end portion is then broken away from the second end portion at the frangible portion to thus render the setting of the device tamper-proof and, for all practical purposes, permanent.
