Abstract
Abstract The invention relates to a collapsible device for the steering column of motor vehicles, which is adapted to recede in case of sudden and strong impact, comprising a pair of members normally assembled and interlocked through sliding surfaces, each member comprising on parallel sliding surfaces conjugate male and female contours, said members being retained in their locked condition by cementing same to each other under calibrated strength conditions, and further comprising means for securing them to separate sections of a steering column.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
Collapsible device for the steering column of motor vehicles, adapted to be sunk when a sudden and strong pressure is exerted thereof, which comprises a pair of members having parallel sliding faces, wherein each one of said members comprises on its sliding face a locking contour, said locking contours being conjugate with each other and having a male and female configuration respectively, said members being retained in their normal locked condition by an injection of plastic cement of calibrated strength, said members further comprising means for securing same to relavant sections of a steering column.
Claim 2
Dependent Claim
95 words
Collapsible device for the steering column of motor vehicles, adapted to be sunk when a sudden and strong pressure is exerted thereof, which comprises a pair of members having parallel sliding faces, wherein each one of said members comprises on its sliding face a locking contour, said locking contours being conjugate with each other and having a male and female configuration respectively, said members being retained in their normal locked condition by an injection of plastic cement of calibrated strength, said members further comprising means for securing same to relavant sections of a steering column.
Claim 3
Dependent Claim
53 words
Device according to claim 1, wherein each one of said members comprises two bearings carrying the one a longitudinal male contour and the other a longitudinal female contour conjugate with said male contour, whereby the collapse is obtained by causing a sliding movement corresponding to one-half of the total length of one member.
Claim 4
Dependent Claim
29 words
Device according to claim 1, wherein a clearance is provided between said male and female contours, thus permitting the interposition of a layer of plastic cement into said clearance.
Claim 5
Dependent Claim
24 words
Device according to claim 1, wherein one of the members or both is or are formed with cavities for receiving said plastic cement therein.
Claim 6
Dependent Claim
24 words
Device according to claim 1, wherein the surfaces in mutual contact of said members are inclined to the general axis of the steering column.
Claim 7
Dependent Claim
16 words
Device according to claim 1, wherein said contours have a substantially omega configuration in cross section.
Claim 8
Dependent Claim
112 words
Steering column comprising two sections having each secured at the end registering with the other section a collapsible device for the steering column of motor vehicles, adapted to be sunk when a sudden and strong pressure is exerted thereof, which comprises a pair of members having parallel sliding faces, wherein each one of said members comprises on its sliding face a locking contour, said locking contours being conjugate with each other and having a male and female configuration respectively, said members being retained in their normal locked condition by an injection of plastic cement of calibrated strength, said members further comprising means for securing same to relevant sections of a steering column.
Claim 9
Dependent Claim
112 words
Steering column comprising two sections having each secured at the end registering with the other section a collapsible device for the steering column of motor vehicles, adapted to be sunk when a sudden and strong pressure is exerted thereof, which comprises a pair of members having parallel sliding faces, wherein each one of said members comprises on its sliding face a locking contour, said locking contours being conjugate with each other and having a male and female configuration respectively, said members being retained in their normal locked condition by an injection of plastic cement of calibrated strength, said members further comprising means for securing same to relevant sections of a steering column.
Claim 10
Dependent Claim
20 words
Steering column according to claim 7, which further comprises a pair of couplings at the opposite ends of said sections.
