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.

The steering column assembly includes a housing having a longitudinal axis, a support member supported by the housing for movement about a shift axis, and a shift lever operatively connected to the support member and extending radially from the shift axis for shifting movement in a limited space. The present invention includes a break-away device having a shear container that extends through a translating bracket and the support member for limiting movement of the shift lever upwardly toward a parallel relationship with the shift axis and for releasing the shift lever for the movement toward the parallel relationship in response to a crash condition.

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.

A telescoping steering column assembly and method of manufacturing the assembly are disclosed. The assembly includes an outer jacket defining at least one hole and a central axis. An inner jacket is disposed in the outer jacket and slides relative to the outer jacket along the central axis. A plug having a body portion and a flange extending radially outwardly from the body portion is disposed in the hole of the outer jacket. The plug defines at least one channel and the plug is heated to create a molten material that flows into the channel of the plug for securing the plug within the hole to prevent movement of the plug along the central axis and for aligning the inner jacket within the outer jacket to allow the inner jacket to slide within the outer jacket.

An adjustable steering column assembly of a vehicle has a central lock device for selectably locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The lock device has a roller actuator preferably having inner outer members with a lever supported operably in between by a guide feature for movement along a first centerline substantially parallel to the steering shaft. Preferably, cam couplers are located between the outer member and the lever and the inner member and the lever for converting movement of the lever along the centerline to longitudinal movement of a carrier that traverses the centerline.

An apparatus and method is provided for absorbing energy. The energy absorbing device includes an anvil movable relative to a spaced axis. The anvil defines a plurality of profiles corresponding to different rates of energy absorption. The plurality of profiles are radially adjacent to one another with respect to axis. The anvil can be moved by explosive charges. For example, the anvil can define a follower portion adjacent a first explosive charge and move in response to an explosion of the first explosive charge.

The telescoping steering column includes a fixed jacket, and telescoping a translating jacket, and an inner tubular member. A wedge, is moved by a screw, into wedging engagement with the inner tubular member to force the inner tubular member into engagement with the translating jacket and the translating jacket into the fixed jacket for preventing relative longitudinal movement.
摘要:
An energy absorbing assembly (20) providing variable energy absorption from an energy transmitting component (10) is mounted upon a mounting bracket (16) for mounting the energy absorbing assembly (20) to the energy transmitting component (10). An elongated strap (22) immovably secured at a first end (24) absorbs energy received from the energy transmitting component (10) during a collision. Cooperating anvils (30A,B) are slidably received by the mounting bracket (16) and the elongated strap (22) is interwoven between the anvils (30). The anvils (30A,B) include generally parallel axes (a) along which each anvil (30A, 30B) defines stepped diameters (A,B,C,D), and are slidable along the axes (a) in response to a predetermined force to provide variable energy absorption relative to the stepped diameters (A,B,C,D).
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.
