Abstract
Abstract A steering column for a motor vehicle comprises two coaxial portions, a first portion being positioned partially within a second portion, and a device disposed between the two portions for transmitting steering forces between two portions and for permitting shortening of the steering column. The device includes two tubular members coaxially positioned one behind the other and mounted in rubber or similar material located in the second portion of the steering column. The tubular members have means on their internal surfaces cooperable with means on the first portion of the steering column for permitting relative longitudinal movement between the tubular members and the first portion and for preventing relative rotation between the tubular members and the first portion. Assembly of the steering column includes inserting the first portion into one of the tubular members, rotating the first portion and the one tubular member relative to the other tubular member, and then continuing to insert the first portion into the other tubular member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
255 words
A steering column for a motor vehicle, said steering column comprising: first and second Steering shaft portions, said first shaft portion being partially positioned within said second shaft portion; and means, positioned between said first and second shaft portions, for transmitting rotation of one of said shaft portions to the other of said shaft portions and for allowing axial movement of one of said shaft portions with respect to the other of said shaft portions, said means comprising: first and second tubular members each fixed to an elastic element fixedly positioned within said second shaft portion, said first and second tubular members being axially positioned one behind the other within said second shaft portion, said first shaft portion extending through said first and second tubular members; said first and second tubular members each having means on the internal surfaces thereof cooperating with means on the external surface of said first shaft portion for allowing relative axial movement between said first shaft portion and said first and second tubular members and for preventing relative rotation therebetween; and said first and second tubular members being circumferentially positioned such that said means on said internal surfaces therof are circumferentially offset with respect to each other when said first shaft portion is not assembled therein, thereby providing means for exerting torsional pressure on said first shaft portion when said first shaft portion is assembled in said first and second tubular members and for thus retarding axial movement between said first shaft portion and said first and second tubular members.
Claim 2
Dependent Claim
255 words
A steering column for a motor vehicle, said steering column comprising: first and second Steering shaft portions, said first shaft portion being partially positioned within said second shaft portion; and means, positioned between said first and second shaft portions, for transmitting rotation of one of said shaft portions to the other of said shaft portions and for allowing axial movement of one of said shaft portions with respect to the other of said shaft portions, said means comprising: first and second tubular members each fixed to an elastic element fixedly positioned within said second shaft portion, said first and second tubular members being axially positioned one behind the other within said second shaft portion, said first shaft portion extending through said first and second tubular members; said first and second tubular members each having means on the internal surfaces thereof cooperating with means on the external surface of said first shaft portion for allowing relative axial movement between said first shaft portion and said first and second tubular members and for preventing relative rotation therebetween; and said first and second tubular members being circumferentially positioned such that said means on said internal surfaces therof are circumferentially offset with respect to each other when said first shaft portion is not assembled therein, thereby providing means for exerting torsional pressure on said first shaft portion when said first shaft portion is assembled in said first and second tubular members and for thus retarding axial movement between said first shaft portion and said first and second tubular members.
Claim 3
Dependent Claim
29 words
A steering column as claimed in claim 1, further comprising a sleeve positioned within said second shaft portion, said elastic element being fixed to the interior of said sleeve.
Claim 4
Dependent Claim
45 words
A steering column as claimed in claim 1, wherein said second shaft has at least one recess therein, and at least one of said tubular members has at least one cam positionable in said recess, there being lateral play between said cam and said recess.
