Embodiment Construction

[0066] [First example of embodiment]

[0067] Figure 1 to Figure 9 It is the first example showing the embodiment of the present invention. In addition, this example is characterized in that it is provided for absorbing the application from the driver's body to the steering wheel 1 during a secondary collision (see Figure 22) The energy absorbing part 35 of the impact energy and the pair and the steering lock device 36, the combination switch 37 (only in Figure 3 ~ Figure 4 The supporting structure of the cables (cable harness) 38 connected with phantom lines in the figure) has been studied. The above-mentioned steering lock device 36 and combination switch 37 are installed on the outer column (rear side) constituting the steering column 3a, respectively. The electrical components at the rear end of column) 10a. Except for the position adjustment function of the steering wheel 1, the structure and function of other parts are basically the same as that of the steering whee...

Abstract

A structure is achieved in which two portions in the axial direction of a cable 38 for electric equipment by an energy-absorbing member 35 on an inner column 9a side and a cable support bracket 52 on an outer column 10a side, such that the cable 38 can be suppressed from becoming a resistance to forward displacement of a steering wheel during a secondary collision. The energy-absorbing member 35 has a support plate section 46, part of which displaces in the downward direction during a secondary collision. Part of the middle section of two portions of the cable 38 in the axial direction is supported by the support plate section 46. During a secondary collision, the middle section of the cable 38 displaces and is bent in the downward direction as the support plate section 46 deforms. As a result, the cable 38 is suppressed from tightening in the axial direction during a secondary collision.

Description

technical field [0001] The present invention relates to an impact-absorbing steering device capable of absorbing impact energy applied from a driver's body to a steering wheel during a secondary collision and capable of being displaced forward of the steering wheel. Background technique [0002] Figure 22 as well as Figure 23 It shows an example of a conventionally known steering device. This steering device has the function of adjusting the up and down position and front and rear position of the steering wheel 1 according to the driver's physique, driving posture, etc., the function of reducing the driver's force to operate the steering wheel 1, and when a collision accident occurs, the driver's In the case of a secondary collision where the body collides with the steering wheel 1, the function of allowing the steering wheel 1 to move forward. In addition, in this specification, the front-back direction, the left-right direction, and the up-down direction mean the front...
