Abstract
Abstract A steering system has a steering shaft carrying at its end a steering wheel, and a steering column through which the steering shaft is extended. A structure for mounting the steering column on the body of a vehicle, comprises: a support bracket having mounting web portions for securing the support bracket to the body, the support bracket being fixed to the outer peripheral surface of the steering column, each mounting web portion having a notch opening in one end edge thereof; a clamping plate associated with each mounting web portion, the clamping plate being formed by bending a metallic sheet into substantially a U-shape so as to provide upper and lower flat plate portions, the flat plate portions being provided with apertures and having slip layers of an electrically insulating material provided on the inner opposing surfaces thereof contacting the associated mounting web portion, each clamping plate being fitted on the mounting web portion by sliding from the side adjacent the steering wheel; and bolts which are driven into threaded holes in the body through the apertures in the clamping plates and the notches of the mounting web portions so as to secure the support bracket to the body. A narrow winding portion integral with the clamping plate extends from a main part of the coating plate, and a free end of the winding portion is electrically connected to the mounting web portion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
245 words
In a steering system of a vehicle, apparatus releasably mounting a steering column to a body of the vehicle for displacement of the steering column in response to driver impact upon a collision of the vehicle and electrically connecting the steering column to the vehicle body to effect electrical connection of an electric circuit to the vehicle body through the steering column, said apparatus comprising: a support bracket fixed to said steering column and having at least one mounting web portion provided with a notch open at one end of said mounting web portion, and a one-piece substantially U-shaped electrically conductive plate member having a pair of spaced, apertured plate portions with opposed inner surfaces provided with slip layers of electrically insulating material, and a winding portion extending from a main portion of one of said plate portions, said plate member being secured to said vehicle body by bolt means extending through respective apertures in said plate portions and through said notch of said mounting web portion, with said mounting web portion being slidably releasably clamped between said inner surfaces of said plate portions to enable said displacement of said steering column, said winding portion having a point of attachment to said mounting web portion remote from said main portion of said one plate portion for displacement with said steering column and for unwinding said winding portion by such displacement, the attachment providing an electrical connection of said plate member to said mounting web portion.

Claim 3
Dependent Claim
17 words
Apparatus according to claim 1, wherein said winding portion winds unidirectionally to form a plurality of turns.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 1, wherein said winding portion winds in substantially zig-zag fashion to form a plurality of turns.
Claim 5
Dependent Claim
38 words
Apparatus according to claim 1, wherein said winding portion includes a portion between said main portion of said one plate portion and said point of attachment and which is bent out of a plane of said main portion.
Claim 6
Dependent Claim
23 words
Apparatus according to claim 4, wherein said bent-out portion of said winding portion is bent in step-like fashion at opposite lengthwise ends thereof.
Claim 7
Dependent Claim
19 words
Apparatus according to claim 1, wherein said bolt means is threaded into a threaded hole of said vehicle body.
Claim 8
Dependent Claim
224 words
Apparatus according to claim 1, wherein said support bracket includes an additional mounting web portion provided with a notch open at an end of said additional mounting web portion corresponding to said one end of the first-mentioned mounting web portion, an additional one-piece substantially U-shaped electrically conductive plate member having a pair of spaced, apertured plate portions with opposed inner surfaces provided with slip layers of electrically insulating material, and a winding portion extending from a main portion of one of said plate portions of said additional plate member, said additional plate member being secured to said vehicle body by bolt means extending through respective apertures in said plate portions thereof and through said notch of said additional mounting web portion, with said additional mounting web portion being slidably releasably clamped between said inner surfaces of said plate portions of said additional plate member to enable said displacement of said steering column, said winding portion of said additional plate member having a point of attachment to said additional mounting web portion remote from said main portion of said one plate portion of said additional plate member for displacement with said steering column and for unwinding said winding portion of said additional plate member by such displacement, the last-mentioned attachment providing an electrical connection of said additional plate member to said additional mounting web portion.
