Abstract:
1. A steering column assembly ( 12 ) with steering shafts ( 31 , 32 ) axially movable along a longitudinal axis but prevented from rotating about the longitudinal axis in relation to each other and disposed in a column jacket ( 8 , 9 ), the column jacket comprising an outer jacket ( 8 ) and an inner jacket ( 9 ), the inner jacket ( 9 ) being axially slidable along the longitudinal axis and disposed in the outer jacket ( 8 ), the outer jacket ( 8 ) is provided with a first through aperture ( 44 ) extending through the outer jacket ( 8 ) defining a second axis transverse to the longitudinal axis, and a frictional plate ( 6 ) located at least partially in the first through aperture ( 44 ) and a radially force transmitting assembly ( 2 , 4 , 5 , 46 ) arranged for applying a radial directed force relative to the longitudinal axis on the frictional plate ( 6 ) resulting in the frictional plate ( 6 ) being pressed against the inner jacket ( 9 ) while maneuvering the force transmitting assembly ( 2 , 4 , 5 , 46 ), with the force transmitting assembly ( 2 , 4 , 5 , 46 ) comprising a first cam member ( 4 ) and a second cam member ( 5 ), each of which includes a number of inclined surfaces ( 510 , 520 , 410 , 420 ) facing each other and with one of the cam members ( 4 ) fixedly mounted in relation to the frictional plate ( 6 ) while an other of the cam members ( 5 ) is rotationally mounted in relation to the frictional plate ( 6 ) and operated by a lever ( 17 ) in order to provide a radial displacement force relative to the longitudinal axis between the two cam members ( 4 , 5 ) by the surfaces which displacement force provides a radial motion acting upon the frictional plate ( 6 ) and directed towards the inner jacket ( 9 ), and with the frictional plate ( 6 ) and the first and second cam members ( 4 , 5 ) being aligned along the second axis.
