摘要： A steering column assembly includes a compression bracket for attachment to a vehicle body, and an adjustable steering column assembly movably supported by the compression bracket along a longitudinal axis between adjusted positions. A pair of locking elements are operably connected to the compression bracket and movable between a locked position for preventing longitudinal movement therebetween and a release position for allowing longitudinal adjustment of the steering column. The first element presents a detent recess, and the second locking element is movable between the locked position engaging the detent recess and the release position out of engagement with the detent recess.

摘要： An apparatus and method is provided for absorbing energy in a collapsible steering column. The energy absorbing device includes an anvil rotatable relative to a strap. The anvil defines a plurality of profiles corresponding to different rates of energy absorption. The plurality of profiles are radially adjacent to one another about the rotational axis of the anvil. The anvil can be rotated by explosive charges. For example, the anvil can define a follower portion and first and second explosive charges can be disposed on opposite sides of the follower portion.

摘要： A steering column assembly includes a rake adjustment mechanism, and is attached to a vehicle by a mounting bracket. A rake bracket is coupled to the mounting bracket. A column jacket is collapsible in response to an emergency event and is supported by the mounting bracket and the rake bracket, and is rotationally moveable with the rake bracket about a rake axis relative to the mounting bracket. An instrument cluster is coupled to the rake bracket for movement along with the rake bracket and the column jacket to prevent obstruction of the instrument cluster by a steering wheel upon re-positioning the steering wheel, while not restricting movement of the column jacket during collapse of the column jacket in response to the emergency event. A dynamic absorber interconnects the instrument cluster and the rake bracket to reduce vibration of the steering column assembly caused by additional weight of the instrument cluster.

摘要： An energy absorbing device for a collapsible steering column of a vehicle is able to compensate for the severity of a crash and the weight of the driver to better manage the absorption of energy in a crash event. A housing has at least one fixed abutment surface, and at least one adjuster disposed in the housing for selective lateral slidable movement. At least one anvil is disposed adjacent an initial abutment surface of the adjuster in spaced relation to the fixed abutment surface of the housing in a first position of the anvil associated with high energy absorption. A plastically deformable strap is supported between the anvil and the housing. The adjuster slides out of the path of the anvil in a crash event in response to input of a control signal allowing the anvil to slide into contact with the fixed abutment surface of the housing to define a second position of the anvil associated with lower energy absorption.

摘要： A telescopically collapsible vehicular steering column assembly includes inner and outer shaft tubes which are joined in a sliding fit by a bushing. The bushing includes a pair of spaced journal bearings formed of steel-backed PTFE held in a plastic carrier body. The bushing is located in a receiving chamber in the outer shaft tube. A clearance compensator reacts against the receiving chamber to exert a radial compressive force through the carrier body and the journal bearings to improve the sliding fit with the inner shaft tube and remove lash. The clearance compensator can take any form, such as a hollow annular rib, a skirt with a flexible free end, or an array of nubs carried in thinned sections of the carrier body. The clearance compensator in all of these variations operates within a clearance space and has dimensional attributes which can be changed during the design and manufacturing phases of the bushing to optimize a characteristic of the steering column assembly. The optimized characteristic may be the sliding friction between the inner and outer shaft tubes, or the stiffness of the assembled column which affects its vibrational frequency, or other value.

摘要： A vehicle steering column has a rake adjustment mechanism which includes a rake bracket having a rake slot provided with rake slot teeth. A tooth lock is supported in the rake slot with teeth opposing the rake slot teeth. A rake bolt is rotatable to a first rotative position to move the tooth lock to a retracted position with the teeth of the tooth lock out of engagement with the rake slot teeth. The bolt is axially rotatable to a second rotative position permitting the tooth lock to be moved to a locking position by a spring in which the teeth of the tooth lock engage the rake slot teeth. The bolt, when in the second rotative position, is movable, in response to an application of an impact force on the steering column to collapse the steering column, into bearing engagement with the tooth lock to positively retain the tooth lock in the locking position. The steering column is also provided with a release mechanism having shear pins and an energy absorption mechanism.

摘要： An energy absorbing device for a collapsible steering column has a plurality of plastically deformable straps each with one end connected to the steering column and an opposite end bent around an anvil connected to stationary vehicle support structure. When the steering column collapses, the straps unwind from the anvils, thereby resisting steering column collapse and absorbing energy. One or more of the straps may be cut in two by a knife at the time of the collision, thereby removing it from the energy absorbing system. In another form of the invention, an energy absorbing strap extends around a piston which has two or more different size anvils. The piston is axially movable in a cylinder to positions surrounding one or another of the anvils. The strap is drawn over the anvil it surrounds when the steering column collapses, thereby resisting collapse of the steering column and absorbing a certain amount of energy depending on the size of the anvil.
