US Patent:

Filed:
May 16, 1985
Appl. No.:
6/734494
Inventors:
John D. Correll - North Ridgeville OH
Assignee:
The Lamson & Sessions Co. - Cleveland OH
International Classification:

US Classification:

Abstract:
An energy absorber system utilizing a pair of housings having facing cavities and with a hollow deformable torsion member interconnecting the housings. One portion of the torsion member is received in the cavity of one housing and another portion of the torsion member is received in the cavity of the other housing. The housing cavities have cross-sectional conformations which receive the torsion member in such a manner that relative rotation therebetween is prevented. Rotation of one housing relative to the other deforms the torsion member elastically and/or plastically. Such deformation absorbs the energy of forces tending to rotate the housings.
