Abstract
Abstract This safety device, adapted to permit the separation of two sections of a steering column assembled by means of one or more universal joints and a connecting joint comprising two separable elements having a common axis of rotation, is characterized in that at least one of the separable elements of the transmission joint comprises an aperture of which the walls are adapted to coact with a driving member rigid with the other element, said last-named element being kept in engagement with the walls of said aperture by means of a tension device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A safety device permitting the disconnection of a pair of sections of a steering shaft assembled by means of at least one universal joint and a connection joint having two separable elements with a common axis of rotation, said connecting joint comprising: a first washer member formed with peripheral notches engaging one section of said steering shaft, a second member carrying a plurality of teeth engaging the other section of the steering shaft, and deformable collar means for holding said plurality of teeth of said second member in engagement with the walls of the notches of the first member whereby the two elements are disconnected from each oTher upon receiving axial or lateral stresses.
Claim 2
Dependent Claim
114 words
A safety device permitting the disconnection of a pair of sections of a steering shaft assembled by means of at least one universal joint and a connection joint having two separable elements with a common axis of rotation, said connecting joint comprising: a first washer member formed with peripheral notches engaging one section of said steering shaft, a second member carrying a plurality of teeth engaging the other section of the steering shaft, and deformable collar means for holding said plurality of teeth of said second member in engagement with the walls of the notches of the first member whereby the two elements are disconnected from each oTher upon receiving axial or lateral stresses.
Claim 3
Dependent Claim
115 words
A safety device permitting the disconnection of a pair of sections of a steering shaft assembled by means of at least one universal joint and a connection joint having two separable elements with a common axis of rotation, said connecting joint comprising: a first strap member provided with an opening permitting the passage of one section of said steering shaft and rigidly connected thereto, a second strap member provided with an opening permitting the passage of the other section of the steering shaft and rigidly connect thereto, and displaceable tension means for holding said first and second members in engagement whereby the two elements are disconnected from each other upon receiving axial or lateral stresses.
Claim 4
Dependent Claim
115 words
A safety device permitting the disconnection of a pair of sections of a steering shaft assembled by means of at least one universal joint and a connection joint having two separable elements with a common axis of rotation, said connecting joint comprising: a first strap member provided with an opening permitting the passage of one section of said steering shaft and rigidly connected thereto, a second strap member provided with an opening permitting the passage of the other section of the steering shaft and rigidly connect thereto, and displaceable tension means for holding said first and second members in engagement whereby the two elements are disconnected from each other upon receiving axial or lateral stresses.
Claim 5
Dependent Claim
64 words
A safety device according to claim 2, in which the sections constituting the steering shaft extending through each strap are parallel and that the displaceable tension means is in bearing engagement with ramps formed on the wings of said straps, whereby the aperture of one strap surrounds the steering shaft section rigid with the other strap during the relative movements of said two straps.
Claim 6
Dependent Claim
124 words
A safety device permitting the disconnection of a pair of sections of a steering shaft assembled by means of at least one universal joint and a connection joint having two separable elements with a common axis of rotation, said connecting joint comprising: a first bell-shaped member engaging one section of said steering shaft and having a frustroconical surface, a second sleeve member engaging the other section of the steering shaft and having a frustroconical surface in engagement with frustroconical surface of said member and spring means interposed between the ends of the said one section and the said other section for holding said first and second members in engagement whereby the two elements are disconnected from each other upon receiving axial or lateral stresses.
Claim 7
Dependent Claim
124 words
A safety device permitting the disconnection of a pair of sections of a steering shaft assembled by means of at least one universal joint and a connection joint having two separable elements with a common axis of rotation, said connecting joint comprising: a first bell-shaped member engaging one section of said steering shaft and having a frustroconical surface, a second sleeve member engaging the other section of the steering shaft and having a frustroconical surface in engagement with frustroconical surface of said member and spring means interposed between the ends of the said one section and the said other section for holding said first and second members in engagement whereby the two elements are disconnected from each other upon receiving axial or lateral stresses.
Claim 8
Dependent Claim
23 words
A safety device according to claim 4, in which the peripheral surfaces of the mutually engaging frustoconical surfaces are formed with matching corrugations.
