Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
88 words
A motor vehicle steering column comprising: a fixedly mounted steering column housing having a section which compresses upon axially applied force, a turnable steering shaft disposed within said housing, said steering column housing having an outer tube and an inner reinforcing sleeve, said inner sleeve has one end fixedly mounted to said outer tube and the other end slidably mounted in an axial direction within the outer tube and in contact with said outer tube to prevent relative radial movement of said inner sleeve and said outer tube.
Claim 2
Dependent Claim
88 words
A motor vehicle steering column comprising: a fixedly mounted steering column housing having a section which compresses upon axially applied force, a turnable steering shaft disposed within said housing, said steering column housing having an outer tube and an inner reinforcing sleeve, said inner sleeve has one end fixedly mounted to said outer tube and the other end slidably mounted in an axial direction within the outer tube and in contact with said outer tube to prevent relative radial movement of said inner sleeve and said outer tube.
Claim 3
Dependent Claim
40 words
Motor vehicle steering column as in claim 1 wherein there is a connection between the outer tube and the reinforcing sleeve slidable end in the form of axially directed corrugations on one of said outer tube and said reinforcing sleeve.
Claim 4
Dependent Claim
41 words
Motor vehicle steering column as in claim 2 wherein said axial corrugations are on said reinforcing sleeve and the outside diameter of the said sleeve corrugations is somewhat larger than the inside diameter of the matching location of the outer tube.
Claim 5
Dependent Claim
38 words
Motor vehicle steering column as in claim 2 wherein said axial corrugations are on the inner surface of said outer tube and the inner diameter of the corrugations is slightly smaller than the outside diameter of the sleeve.
Claim 6
Dependent Claim
27 words
Motor vehicle steering column as in claim 1 further comprising a bushing between the tube and sleeve to provide bearing support of sleeve inside the outer tube.
Claim 7
Dependent Claim
17 words
Motor vehicle steering column as in claim 5 wherein the bushing has corrugations in the axial direction.
Claim 8
Dependent Claim
34 words
Motor vehicle steering column according to claim 1 wherein the axial displacement distance of the sleeve in regards to the outer tube substantially equals the length of the connection area of sleeve and tube.
Claim 9
Dependent Claim
77 words
Motor vehicle steering column as in claim 1 wherein the steering column housing comprises said outer tube to which a collapsible tubular section is attached, with the outer tube having a section disposed radially within the collapsible tube section, the inner reinforcing sleeve overlapping said section of said outer tube such that the overlap length of the inner reinforcing sleeve and said section of said outer tube being at least twice the diameter of the outer tube.
Claim 10
Dependent Claim
25 words
Motor vehicle steering column as in claim 8, wherein the reinforcing sleeve is a spring sleeve in the area where it engages said first tube.
Claim 11
Dependent Claim
27 words
Motor vehicle steering column as in claim 9, wherein the sleeve is slotted along the entire length of the portion which engages said first sleeve first section.
Claim 12
Dependent Claim
16 words
Motor vehicle steering column as in claim 10, wherein the spring sleeve is of cold-rolled steel.
Claim 13
Dependent Claim
36 words
Motor vehicle steering column as in claim 11, wherein the end of the collapsible tubular section fits around said outer tube and located towards the steering wheel, has axially directed slots to produce a press-slide slit.
Claim 14
Dependent Claim
17 words
Motor vehicle steering columns in claim 8, wherein the reinforcing sleeve is provided with a rounded-off edge.
