  • Patent number: 7255366
    Abstract: A steering column assembly for operating a vehicle packages mechanical components and electrical devices normally found in or around the steering column of the vehicle into a single unit. An on-board processor accepts signals from the electrical devices, which may include a steering sensor, an acceleration pedal sensor, a brake pedal sensor, a turn signal switch, a cruise control switch, a windshield wiper switch, etc. The on-board processor connects to a vehicle communications bus to communicate data received from the electrical devices to various systems throughout the vehicle. The on-board processor also receives data from the various systems. The steering column assembly also includes a display connected to the on-board processor. The operator receives information about the operation of the vehicle from the display. All components, including the on-board processor, are operatively connected to a column support, allowing the steering column assembly to be installed as a unit.

  • Patent number: 7229096
    Abstract: The invention provides an apparatus for absorbing energy in a collapsible steering column of a vehicle. A portion of the apparatus is deformable in response to an excessive frontal impacting force to the steering column so that injury to the vehicle operator is reduced. The apparatus includes a first steering column member and a second steering column member connected to one another such that the first steering column member slides relative to the second steering column member. The apparatus also includes a first anvil associated with a said first steering column member and a second anvil associated with said second steering column member. The apparatus also includes an energy absorbing member having a first portion extending around and operable to be drawn over said first anvil and a second portion extending around and operable to be drawn over said second anvil.

  • Patent number: 7228755
    Abstract: A vehicular steering column assembly (16) comprises a support bracket (26) which is joined to an outer, non-rotating sleeve (22). A release capsule (30) is releasably joined to a mounting surface (28) of the support bracket (26) via a plurality of spherical bodies (56) whose protruding crowns (52) are seated in corresponding longitudinally-extending furrows (54) in the release capsule (30). Upon the application of sufficient force to the steering column (16), such as during a collision, the support bracket (26) is urged out of engagement with the release capsule (30) with the respective furrows (54) sliding over the crowns (52). The sliding engagement between the crowns (52) and the furrows (54) can be adjusted to establish a highly predictable and consistent release force and which is capable of increasing the frequency value for the steering column (16).

  • Patent number: 7226083
    Abstract: The subject invention provides a collapsible steering column assembly. The assembly includes a support for attachment to a vehicle. A steering column is movably supported by the support. An energy absorbing mechanism interconnects the steering column and the support for absorbing energy in response to the steering column moving relative to the support during a collision. The energy absorbing mechanism includes a elongated element and a brake for variably resisting the movement of the elongated element and absorbing the energy during the collision. The elongated element, in combination with the brake, is capable of adjustment to absorb energy at forces of various magnitude such that a universal energy absorbing device may be installed on each type of vehicle. Furthermore, the elongated element retains structural integrity after absorbing the energy and need not be replaced.

  • Patent number: 7178833
    Abstract: A steering column assembly is disclosed featuring a steering column carried by a release bracket having parallel connecting walls interposed between spaced sidewalls of a mounting bracket, which is for attachment to a vehicle subassembly. Shear capsules are releasably disposed within respective rearwardly-opening primary notches on the connecting walls. The capsules are connected to the mounting bracket by being disposed in respective secondary notches on the sidewalls. The capsules shear in response to an axial shear force above a predetermined threshold value and release the connecting walls to permit the steering column to collapse.

  • Patent number: 7178834
    Abstract: The present invention provides an apparatus for supporting a steering wheel in a vehicle during normal vehicle handling and is breakable in response to an impact situation. The apparatus includes a member attachable to a vehicle and a steering column connected to the member for sliding movement. The apparatus also includes a capsule for connecting the member and the steering column to one another to prevent the sliding movement during normal vehicle handling. The capsule maintains the member and the steering column relative to one another, overcoming forces urging movement between the member and the steering column relative to one another, up to a first predetermined level of force. When the forces reach the first predetermined level, such as in an impact situation, the capsule breaks and releases the member and the steering column relative to one another.

  • Patent number: 7137499
    Abstract: The invention provides an apparatus for shifting an automatic transmission having a shift position select lever. The invention selectively shifts the transmission to one of a plurality of different transmission shift positions. The invention includes a steering column positionable in a passenger compartment of a vehicle. A switch is mountable in the passenger compartment of the vehicle and operable to emit a first signal representative of a desired change with respect to a transmission shift position. A motor generates a moving force and a linkage associated with the motor to transmit the moving force from the motor to a shift lever of a transmission of the vehicle. A sensor is responsive to a current transmission shift position and emits a second signal corresponding to the sensed current transmission shift position. A controller is responsive to the switch and to the sensor.

  • Patent number: 6877775
    Abstract: 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).

  • Publication number: 20040239089
    Abstract: An apparatus for positioning a steering wheel of a vehicle in a desired position. The invention includes a steering column having a steering wheel supporting portion for supporting the steering wheel. The steering column also includes first and second members movable relative to one another. The first and second members are moved relative to one another to move the steering wheel supporting portion, and the steering wheel, along either tilting path of movement, or a telescoping path of movement, or both. The invention also includes a locking device that selectively engages the first and second members to lock the first and second members with respect to one another. The locking device substantially prevents movement of the steering wheel supporting portion, and the steering wheel, along the path of movement. The locking device includes an electric motor. The first and second members are locked and unlocked with respect to one another in response to activation of the electric motor.
