摘要： An energy absorber for a motor vehicle steering column including a yoke pivotable about a lateral centerline of a motor vehicle body and an energy absorbing means between the yoke and the mast jacket responsive to linear translation of the mast jacket relative to the yoke. The mast jacket extends through a bore in the yoke and a plastic bushing in the bore prevents the mast jacket from tilting relative to the yoke before and during linear translation of the mast jacket. The energy absorbing means includes a flat metal strap attached at one end to the mast jacket and bent over a convex anvil on the yoke. The metal strap is pulled over the anvil parallel to a longitudinal centerline of the mast jacket and plastically deformed to convert into work a fraction of the kinetic energy of an impact on the steering column. Because the mast jacket pivots as a unit with the yoke, the metal strap is always parallel to the longitudinal centerline of the mast jacket and the vector force reaction on the mast jacket attributable to the energy absorber intersects the lateral centerline.

摘要： An anti-theft steering shaft lock for an energy-absorbing motor vehicle steering column having a linearly collapsible mast jacket includes a unitized construction consisting of a cylinder lock attached to an instrument panel of the motor vehicle remote from the mast jacket, a lateral housing between the cylinder lock and the mast jacket, a lock bolt in the lateral housing, rack and pinion gears which convert rotation of an element of the cylinder lock into linear translation of the lock bolt, and a frangible connection means at which an inboard part of the unitized construction adjacent the mast jacket separates from an outboard part in the direction of linear collapse of the mast jacket. The frangible connection means includes a pair of laterally aligned frangible joints between inboard and outboard segments of the lateral housing and between inboard and outboard segments of the lock bolt. The inboard part of the unitized construction constitutes a relatively small rigid appendage to the mast jacket so that the space behind the instrument panel dedicated to maintenance of a clear path for such rigid appendage is, likewise, relatively small.

摘要： An energy absorber for a motor vehicle steering column including a yoke pivotable about a lateral centerline of a body of the motor vehicle and an energy absorbing structure responsive to linear translation of a mast jacket of the steering column relative to the yoke in the direction of a longitudinal centerline of the mast jacket. The mast jacket extends through a bore in the yoke and is prevented by the bore from tipping relative to the yoke. The energy absorbing structure includes a convex anvil on the mast jacket and a J-shaped flat metal strap seated on the convex anvil with a short leg rigidly attached to the yoke and a long leg juxtaposed a wall of the mast jacket. An impact on the steering column initiates linear translation of the mast jacket in the direction of its longitudinal centerline relative to the yoke during which the convex anvil translates linearly relative to the stationary metal strap so that the metal strap is pulled over the convex anvil and plastically deformed to convert into work a fraction of the kinetic energy of the impact.

摘要： An energy absorbing device for a collapsible steering column of a vehicle includes an M-shaped plastically deformable strap for imposing a resistance to collapse of the steering column when the steering column collapses in a vehicle collision. An anvil adjusts the resistance to collapse imposed on the steering column by the strap. A controller produces a signal of a magnitude indicative of an amount of resistance needed to be imposed on the steering column by the strap to better protect from injury a driver seated behind the steering column at the time of the collision. An actuator receives the signal and actuates the anvil to adjust the amount of resistance imposed by the strap in accordance with the magnitude of the signal.

摘要： The lower bracket assembly for a vehicle steering column includes a lower column support bracket with a central passage. A lower bearing adapter slides into the central passage from the rear. A pair of energy absorption straps engage the column support bracket and the lower bearing adapter and resist further forward movement of the lower bearing adapter. During a collision, the energy absorption straps absorb energy while permitting the lower bearing adapter to move forward and out of the central passage through the column support bracket.

摘要： An energy absorbing device includes a plastically deformable metal strap for resisting the collapse of a steering column. The strap is initially deformable into one or more V-shaped wave formations by anvils to increase the energy required to advance the strap, thereby increasing the resistance to collapse of the steering column. One of the anvils may be removed to eliminate one of the wave formations and thereby reduce the amount of resistance to collapse of the steering column. Alternatively, the position of an anvil may be varied to vary the shape of a wave configuration from a deep V to a shallow V.

摘要： An actively variable energy absorber including a convex anvil on a steering column housing, a flat metal strap attached to a steering column support and slidably engaging the convex anvil on an active surface area of the convex anvil, and a control apparatus for actively varying the geometric relationship between the flat metal strap and the convex anvil in response to changes in a control variable thereby to adjust the magnitude of the active surface area. Adjusting the magnitude of the active surface area changes the severity of plastic deformation of the flat metal strap and the magnitude of the friction between the flat metal strap and the convex anvil thereby to adjust the force resisting linear translation of the steering column housing. In some embodiments of the actively variable energy absorber, the flat metal strap is plastically deformed by being pulled over a single convex anvil during linear translation of the steering column housing. In other embodiments of the actively variable energy absorber, the flat metal strap is plastically deformed by being pulled across a plurality of convex anvils or by being pulled edgewise between a pair convex anvils.

摘要： The fine increment tilt mechanism for a vehicle steering column includes a steering column support housing and a tilt housing pivotally connected to the support housing for pivotal movement about a tilt axis. A plurality of fixed teeth on the support housing are engaged by a plurality of pivoted shoe teeth on the tilt housing to fix the tilt housing relative to a tilt axis. A shoe release lever includes a wedge that is moved to a position in which the pivoted shoe teeth are held in engagement with the fixed teeth after the tilt housing is pivoted about the tilt axis to a selected position.
