Claim 10

The interconnector of claim 2 in which said recess means are carried on said outer housing and comprises a ring of recesses surrounding said rotor and facing in an axial direction, said flexible detent means comprising a spring metal strip member residing in said second aperture, said strip member comprising an extension that extends out of said aperture and is normally biased into engagement with at least one of said recesses to resist rotation between said outer housing and rotor member, said strip member also defining an inwardly extending loop section, whereby a steering column entering said second aperture may collapse said loop section to cause axially outward movement of said extension out of engagement with said recesses.

Claim 11

The interconnector of claim 2 which is adapted to receive a portion of a vehicle steering column in said second aperture, said rotor member carrying first hinged bar members in said second aperture, said rotor member also carrying second hinged bar members which are biased to engage at their outer ends said recess means, said recess means being open to one side of said interconnector whereby said steering column, when present, biases said first, hinged bar members to press said second, hinged bar members out of the open one side of the recess means and out of engagement with said recess means to permit rotation between said outer housing and said rotor member.

Claim 12

The interconnector of claim 1 in which said coiled conductor means comprises a plurality of parallel conductor wires bonded together in a band of unitary, flexible insulation with the wires positioned in coplanar relation.

Claim 13

The interconnector of claim 11 in which at least one end of said band defines a slit in said insulation between two of said conductor wires and parallel thereto, said slit terminating short of the other end of said band, to form a pair of half band portions joined together at said one end, one half band portion being folded to lie substantially on top of the other, and means for providing electrical connection with the ends of said conductor wires.

Claim 14

The interconnector of claim 12 in which at least one end of said band carries a series of relatively thick members, said members being in relatively hinged relation to each other, whereby said one end of the band is flexible to form arcs of varying curvature but cannot be folded into a sharp, 180 degree fold.

Claim 15

An electrical interconnector member which comprises: an outer housing defining a first aperture; a rotor member occupying said first aperture in rotational relation thereto; a first electrical connection carried on said outer housing; a second electrical connection carried on said rotor member; and coiled conductor means loosely coiled about said rotor member within said outer housing, said coiled conductor means being connected at respective ends thereof to the first and second electrical connections; the improvement comprising, in combination: recess means carried by said outer housing and flexible detent means carried by the rotor member, said detent means being normally positioned to project into said recess means to inhibit rotation between said outer housing and rotor member when said interconnector member is not mounted on a device such as a vehicle steering column, said detent means being positioned and proportioned whereby said mounting of said interconnector member for use on a device such as said vehicle steering column causes said detent means to be flexed out of projecting relation with said recess means, to permit rotation between the outer housing and rotor member, said recess means comprising a plurality of recesses facing inwardly toward said rotor member.

Claim 16

An electrical interconnector member which comprises: an outer housing defining a first aperture; a rotor member occupying said first aperture in rotational relation thereto; a first electrical connection carried on said outer housing; a second electrical connection carried on said rotor member; and coiled conductor means loosely coiled about said rotor member within said outer housing, said coiled conductor means being connected at respective ends thereof to the first and second electrical connections; the improvement comprising, in combination: recess means carried by said outer housing and flexible detent means carried by the rotor member, said detent means being normally positioned to project into said recess means to inhibit rotation between said outer housing and rotor member when said interconnector member is not mounted on a device such as a vehicle steering column, said detent means being positioned and proportioned whereby said mounting of said interconnector member for use on a device such as said vehicle steering column causes said detent means to be flexed out of projecting relation with said recess means, to permit rotation between the outer housing and rotor member, said recess means comprising a plurality of recesses facing inwardly toward said rotor member.

Claim 17

The interconnector of claim 14 in which said detent means defines individual detents which each define a finger member connected by a plastic hinge to said rotor, said finger member carrying an integral spring extension member which abuts against an inward face of said outer housing, whereby said detent means engages said recess means.
