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 force exerted on the steering wheel 1 from the driver's body in the event of a secondary collision (see Figure 22) The energy absorbing part 35 of the impact energy and the pair with the steering lock device 36, the combination switch 37 (only in Figure 3 ~ Figure 4 The support structure of the cables (cable harness) 38 connected with phantom lines in ) 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 the 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 w...

Abstract

The present invention pertains to a structure for supporting portions in two sites in the axial direction of a cable (38) of an electrical component, the portions between supported between an energy-absorbing member (35) near an inner column (9a) and a cable supporting bracket (52) near an outer column (10a), the cable (38) being capable of minimizing resistance against frontward displacement a steering wheel accompanying a secondary impact. The energy-absorbing member (35) has a supporting plate part (46) in which a portion thereof is displaced downward during a secondary impact. A portion of a medial part between the portions in two sites in the axial direction of the cable (38) is supported by the supporting plate part (46). The medial part of the cable (38) bends under downward displacement accompanying deformation of the supporting plate part (46) during a secondary impact. Consequently, axial stiffening of the cable (38) is suppressed during a secondary impact.

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...
