1,253,222. Energy absorbing devices; brakes. ARA Inc. 8 Oct., 1968 [22 Jan., 1968], No. 47639/68. Headings F2E and F2S. In an impact-energy absorbing device 12 employing the cyclic plastic deformation principle described in Specification 1,195,435, a bushing 103 located between the inner cylinder 18 and outer tube 42 of the device absorbs shock in non-axial directions. The bushing is of P.T.F.E. or the like and consists of a flange 130 and a stem 132. Axial relative movement of the telescoped parts 18 and 42 causes cyclic plastic deformation of elements 76 as described in the prior patent: any non-axial movement will deform the stem of the bushing and be thereby resisted. |
