ABSTRACT:
The breakaway vehicular steering assembly has a tube and a shaft normally operable as a unit. The tube and the shaft are held together by a shearpin which will shear at the application of a predetermined axial force.
A portion of the tube is channelled; the shaft fits within the channel. A ramp extending from the walls of the tube is adapted to move the shaft outwardly from the channel after the shearpin has been broken and the shaft moved axially within the channel and along the ramp. As the shaft moves out from the channel, a metal band innerconnecting the side walls of the channel is broken at a predetermined force and alignment tabs extending outwardly from the tops of the side walls of the channel in the tube are expanded so that the shaft is completely removed from the channel.
