Abstract
Abstract An electrical connection is provided adapted to be mounted on the steering wheel of a motor vehicle, for example to establish a connection with an inflatable air bag disposed at the center of the steering wheel. The connection comprises a continuous sheathed flat cable, a central region of which is coiled into a large number of helical turns, so that the cable forms a flat spiral, with the flat cable being placed on edge, so that the plane of the cable is perpendicular to the plane of the flat spiral. The ends of the cable are bent to extend out of the plane of the spiral, substantially at right angles. These projecting ends of the flat cable are encased in an extra sheath of insulating material which extends along some of the cable at the ends of the spiral and along the whole length of the projecting end parts of the cable to provide additional tensile strength at the ends of the flat cable. The ends of the cable are provided with plug-and-socket connectors.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
An electrical connector, said connector comprising a continous flat cable extending throughout the connector, said flat cable comprising conductors encased in a first insulative sheath having dimensions of width and thickness, with the width being greater than the thickness, a central portion of said flat cable being coiled into a plurality of turns which define a flat spiral, said cable being coiled so that said cable is place on edge the edges of said cable lying in two parallel planes, said cable having two end portions and two bent portions adjacent to said end portions, said bent portions being bent so that said end portions of said cable project outwardly from the spiral and substantially perpendicularly to said parallel planes, said end portions of said cable each being encased in a flexible one-pieces extra sheath which extends along the whole length of a respective one of said projecting end portions and which also extends past a respective one of said bent portions of the cable along part of said spiral.
Claim 2
Dependent Claim
170 words
An electrical connector, said connector comprising a continous flat cable extending throughout the connector, said flat cable comprising conductors encased in a first insulative sheath having dimensions of width and thickness, with the width being greater than the thickness, a central portion of said flat cable being coiled into a plurality of turns which define a flat spiral, said cable being coiled so that said cable is place on edge the edges of said cable lying in two parallel planes, said cable having two end portions and two bent portions adjacent to said end portions, said bent portions being bent so that said end portions of said cable project outwardly from the spiral and substantially perpendicularly to said parallel planes, said end portions of said cable each being encased in a flexible one-pieces extra sheath which extends along the whole length of a respective one of said projecting end portions and which also extends past a respective one of said bent portions of the cable along part of said spiral.
Claim 3
Dependent Claim
16 words
A connector according to claim 1, wherein each said extra sheath is an integrally molded sheath.
Claim 4
Dependent Claim
18 words
A connector according to claim 2, wherein each said extra sheath is molded of an electrically insulating material.
Claim 5
Dependent Claim
42 words
A connector according to claim 1, wherein each said sheath extra is shaped in a region of a respective one of said bent portions of said flat cable to form an abutment for securing said region of said cable in a covering.
Claim 6
Dependent Claim
20 words
A connector according to claim 4, wherein each said abutment is shaped for rigidly securing said cable in the covering.
Claim 7
Dependent Claim
17 words
A connector according to claim 1, wherein at least one said extra sheath has an oval cross-section.
Claim 8
Dependent Claim
16 words
A connector according to claim 1, wherein at least one said sheath has a circular cross-section.
Claim 9
Dependent Claim
36 words
A connector according to claim 1, wherein at least one said extra sheath has a substantially flattened cross-section along at least part of its length between an end of said cable and the respective bent portion.
Claim 10
Dependent Claim
18 words
A connector according to claim 1, wherein said end portions of said cable are provided with plug-and-socket connections.
Claim 11
Dependent Claim
188 words
A connector connected to the igniter of an inflatable air bag mounted in the steering wheel of a motor vehicle, said connector being formed from a continuous flat cable comprising conductors encased in a first insulative sheath having dimensions of width and thickness, with the width being greater than the thickness, said cable having a first end portion connected to the igniter, a central portion, a second end portion, and bent portions, each of said bent portions being adjacent to a respective end portion, said central portion of said cable being coiled into a plurality of turns to form a flat spiral, said cable being placed on edge the edges of the cable lying in two parallel planes, said first end portion and said second end portion extending in opposite directions from the spiral and substantially perpendicular to said parallel planes, each of said end portions being encased in a flexible one-piece extra sheath which extends along the whole length thereof and which extends past a respective one of said bent portions of said cable and along a portion of said cable defining an end of the spiral.
Claim 12
Dependent Claim
188 words
A connector connected to the igniter of an inflatable air bag mounted in the steering wheel of a motor vehicle, said connector being formed from a continuous flat cable comprising conductors encased in a first insulative sheath having dimensions of width and thickness, with the width being greater than the thickness, said cable having a first end portion connected to the igniter, a central portion, a second end portion, and bent portions, each of said bent portions being adjacent to a respective end portion, said central portion of said cable being coiled into a plurality of turns to form a flat spiral, said cable being placed on edge the edges of the cable lying in two parallel planes, said first end portion and said second end portion extending in opposite directions from the spiral and substantially perpendicular to said parallel planes, each of said end portions being encased in a flexible one-piece extra sheath which extends along the whole length thereof and which extends past a respective one of said bent portions of said cable and along a portion of said cable defining an end of the spiral.
Claim 13
Dependent Claim
42 words
A connector according to claim 1, wherein each said extra sheath is shaped in a region of a respective one of said bent portions of said flat cable to form an abutment for mounting said region of said cable on a covering.
