Patent number: 8197348Abstract: A telescopic shaft for vehicles comprising an inner shaft axially movable in an outer shaft. The telescopic shaft comprises at least two rows of balls with at least one ball per row between the inner shaft and the outer shaft. A row of balls is arranged on at least one ball race arranged against the inner shaft. The ball race is wedge shaped on its against the inner shaft facing surface. The telescopic shaft comprises a prestress mechanism which pushes the ball race along a wedge unit axially in relation to and radially in the direction against the outer shaft. whereby the telescopic shaft is prestressed. The prestress mechanism is arranged to release the prestress when the alteration in length of the telescopic shaft exceeds a predetermined length.Type: GrantFiled: May 28, 2008Date of Patent: June 12, 2012Assignee: Fuji Autotech ABInventors: Ulf Eriksson, Hans Fredriksson

Patent number: 8117940Abstract: A steering wheel arrangement for a motor vehicle includes a steering column having a first end for cooperation with a steering wheel and a second end for cooperation with a vehicle steering mechanism. The steering wheel arrangement further includes a suspension arrangement for the steering column. The suspension arrangement includes two pivot joints and is pivotally connected to the steering column via a third pivot joint, the first, second and third pivot joints including first, second and third locking arrangements, respectively. The steering wheel arrangement has thus three adjustable pivot points where only one or two of the three pivot joints are adjustable in a first step depressing a foot pedal to a first position and only the remaining of the three pivot joints are adjustable in a second step depressing the foot pedal to a second position which implies that the adjustments can be made in a secure way by the driver during the ride.Type: GrantFiled: October 28, 2005Date of Patent: February 21, 2012Assignees: Volvo Lastvagnan AB, Fuji Autotech ABInventors: Björn Andersson, Hassan Omarain, Andreas Alvehav, Thomas Paulsson, Hans Fredriksson, Ulf Eriksson, Pentti Hyvönen
