ABSTRACT:
An energy absorber comprises a helically coiled stores of at least partially yielding material that is drawn over a roller, or two rollers on perpendicular rotational axes, and securely fixed to a base that is attached to fragile structure such as a roof so that when an external force of sufficient size is applied to the roller or rollers through a connecting attachment eye the coil together with roller or rollers moves away from the attachment to the base whilst the coiled material is deployed over the roller or rollers. The absorber may be housed in a casing that is fixed to the base such that the strength of the fixing to the base is sufficient to withstand a predetermined load after which the fixing fails and the housing moves with the coiled store providing protection for both the coiled store and fragile structure.
