Steering post support device

Abstract

There is provided a steering column supporting apparatus in which tilt pins are locked on a tilt bracket fixed to a vehicle body and engaged with tilt plates welded to respective both sides of a steering column, and slotted holes extended in the axial direction of the steering column are formed in the tilt plates. A bulging part is formed on a lower surface of the steering column, and is designed to be larger in size than a gap between the lower surface of the steering column and the tilt bracket and increased in height as it goes rearward in the direction of the length of a vehicle. Therefore, it is possible to effectively reduce impact load applied to the steering column in the event of head-on vehicle crash.

Description

[0001] Cross References to Related Applications [0002] This application refers to the subject matter of Patent Application No. 2003-137616 filed in Japan on May 15, 2003, from which the present application claims priority. technical field [0003] The present invention relates to a steering column in which a vehicle steering shaft is disposed; and more particularly, the present invention relates to a support device for a tilting steering column capable of absorbing a shock applied in a head-on collision of a vehicle. Background technique [0004] Generally, as a support structure for a tilt steering column of a vehicle, a support structure disclosed in Japanese Patent Laid-Open No. 11-115770 and Japanese Utility Model Publication No. 62-23771 is known. [0005] The support structure disclosed in Japanese Patent Laid-Open No. Hei 11-115770 has a problem that the steering column cannot absorb energy when the steering column is released forward from the vehicle body in the ve...

Problems solved by technology

[0005] The support structure disclosed in Japanese Patent Laid-Open No. Hei 11-115770 has the problem that the steering column cannot absorb energy when the steering column is released forward from the vehicle body in the vehicle length direction

[0006] Also, the support structure disclosed in Japanese Utility Model Publication No. 62-23771 has the problem that the position of the steering wheel held by the support pin for tilting the steering column (ie, the position of the steering wheel at the rear end of the steering column position) is unstable because the bearing pin moves; at the same time, the edge of the slot is crushed and therefore only little impact energy can be absorbed

Therefore, for example, when the airbag is mounted on the steering wheel, the form in which the airbag inflates toward the driver may be unstable
