no. 3 Embodiment approach

[0167] Figure 24 to Figure 26 An example of the third embodiment of the present invention is shown. In addition, this example is characterized in that, in order to suppress the load required to start the forward displacement of the locking member 47d (47e) relative to the vehicle body side bracket 11e when a secondary collision occurs, the vehicle body The mounting direction (mounting posture) of the side bracket 11e with respect to the bracket 33a on the column side is designed. The structure and function of other parts of this example are the same as those of each example of the first embodiment and the second embodiment, so illustration and description of the same parts are omitted or simplified, and the following description will focus on the characteristic parts of this example.

[0168] In this example, the locking member 47d is fastened to the upper surface of the bracket 33a on the column side by a plurality of (three in the illustrated example) bolts 51 and nuts 52 ...

Abstract

A steering column support apparatus that is capable of simplifying tuning for stabilizing forward displacement of a steering wheel during a secondary collision, keeping material costs, processing costs and assembly costs of an energy absorbing member low, and when necessary, preventing the steering wheel from dropping down excessively during a secondary collision. A locking capsule 47 that is fastened to a bracket 3 on the column side is held inside a locking hole 45 of a bracket 11b on the vehicle side that is fastened to the vehicle body by a plurality of connecting members that shear during a secondary collision. An energy absorbing member 53 is placed between the locking capsule 47 and the bracket 11b on the vehicle side. This energy absorbing member 53 is formed by bending a plastically deformable wire, and allows forward displacement of the locking capsule while absorbing impact energy that is applied to the locking capsule by plastically deforming during a secondary collision.

Description

technical field [0001] The present invention relates to a steering column support device for absorbing impact energy applied from a driver's body to a steering wheel when a collision accident occurs, and supporting the steering column on a vehicle body so as to be displaceable in the forward direction. Background technique [0002] Such as Figure 33 As shown, the automobile steering device is configured to transmit the rotation of the steering wheel 1 to the input shaft 3 of the steering gear assembly unit 2, and push and pull a pair of left and right tie rods 4 with the rotation of the input shaft 3, so as to control the steering wheels. The front wheels apply the steering angle. The steering wheel 1 is supported and fixed to a rear end portion of a steering shaft 5 , and the steering shaft 5 is rotatably supported by the steering column 6 in a state penetrating in the axial direction through a cylindrical steering column 6 . In addition, the front end of the steering sha...
