Abstract
A steering apparatus includes an engaging portion movable in a predetermined moving direction at a time of a secondary collision; a fixation portion fixed to a vehicle body; and an absorbing member. The absorbing member includes a fixed portion fixed to the fixation portion, an engaged portion facing the engaging portion, and a connecting portion that includes a curved portion and connects the fixed portion and the engaged portion. An area of a cross-section of the curved portion taken along a plane perpendicular to a creeping direction along the curved portion varies depending on a position in the creeping direction. The connecting portion of the absorbing member is deformed so that the absorbing member absorbs energy of the secondary collision.
Claims14
A steering apparatus comprising:
- a bracket that supports a steering shaft connected to a steering member and that is movable to a downstream side in a predetermined moving direction together with the steering member at a time of a secondary collision;
- an engaging portion that is disposed so as to be integrally movable together with the bracket;
- a fixation portion whose relative position with respect to a vehicle body is fixed, the relative position being fixed before and after the secondary collision;
- and
- an absorbing member,
- wherein the absorbing member includes a fixed portion fixed to the fixation portion, an engaged portion facing the engaging portion from the downstream side in the moving direction, and a connecting portion that includes a curved portion and connects the fixed portion and the engaged portion, and an area of a cross-section of the curved portion taken along a plane perpendicular to a creeping direction along the curved portion varies depending on a position in the creeping direction, and
- wherein at the time of the secondary collision, the connecting portion of the absorbing member is deformed due to engagement between the engaging portion and the engaged portion so that the absorbing member absorbs energy of the secondary collision.
