An energy-absorbing device for use with a counterbalance mechanism to relatively harmlessly absorb energy potentially released should a component of the counterbalance mechanism fail. A frame is attached to a portion of the counterbalance mechanism and supports an impact receiving member, and a plurality of deformable support members. In the event of a failure in the counterbalance mechanism, a part of the counterbalance mechanism strikes a face of the impact receiving member. Deformable support members are attached to the opposing face of the impact receiving member and are deformed by the impact and thus absorb the energy that is transferred by the impact. The deformable support members and the impact receiving member are readily replaceable.
