Steering column device

摘要

A steering column device includes a steering column for supporting a steering shaft in a freely rotatable manner, and a guide plate and a column bracket for assembling the steering column onto a part of a vehicle body. The steering column device further includes coupling bolts coupled to the column bracket through guide grooves of the guide plate and movable along the guide grooves when the column bracket moves toward the front of the vehicle relative to the guide plate. Further, an upper column cover movable toward the front of the vehicle together with the steering column is assembled above the steering column at a position corresponding to a vehicle rear of the guide plate. A unit for mitigating an impact is provided to a vehicle rear portion of the guide plate, and is configured to mitigate an impact to be caused when the upper column cover strikes, in the event of collision of the vehicle, against the vehicle rear portion of the guide plate along with movement of the steering column toward the front of the vehicle together with the column bracket.

1. A steering column device, comprising:
a steering column for supporting a steering shaft in a freely rotatable manner; a guide plate having a guide groove extending in a fore-and-aft direction of a vehicle along a column axis direction,
the guide plate being fixed to a vehicle body at a position above the steering column; a column bracket for supporting the steering column at a position below the guide plate,
the column bracket being assembled onto the guide plate so as to be movable toward a front of the vehicle relative to the guide plate; a coupling member coupled to the column bracket through the guide groove of the guide plate,
the coupling member being movable along the guide groove when the column bracket moves toward the front of the vehicle relative to the guide plate; and an upper column cover assembled above the steering column at a position corresponding to a vehicle rear of the guide plate,
the upper column cover being movable toward the front of the vehicle together with the steering column, the guide plate comprising, at a vehicle rear portion thereof, means for mitigating an impact to be caused when the upper column cover strikes, in an event of collision of the vehicle, against the vehicle rear portion of the guide plate along with movement of the steering column toward the front of the vehicle together with the column bracket, the means for mitigating an impact comprising means for guiding the upper column cover toward a lower side of the guide plate, the means for guiding comprising a breaking portion for breaking an upper front portion of the upper column cover.
