Patent number: 7240920Abstract: A vehicle occupant knee protection apparatus for protecting the knees of an occupant when collision energy acts on a vehicle. The occupant knee protection apparatus comprises a knee protection member, a contact force detector, a controller, and a drive unit. The knee protection member is disposed in an opposable position to knees of an occupant seated in a vehicle seat. The contact force detector detects the contact force of the knees on the knee protection member. The controller performs control that reduces the contact force to a force control target value and that maintains the reduced value. The drive unit moves the knee protection member in the front/rear direction of the vehicle on the basis of an output signal from the controller.Type: GrantFiled: June 28, 2006Date of Patent: July 10, 2007Assignee: Honda Motor Co., Ltd.Inventors: Yasuki Motozawa, Daisuke Fuji, Hidekazu Nishimura, Yoichi Amano

Patent number: 7198294Abstract: A roll bar assembly capable of punching through a rear window (12) on deployment comprises a deployable u-shaped roll bar (1) fitted with a pin (4) made of hard material. An item of trim (5) is located over the top of the roll bar (1) by means of a pair of spring clips (7,8). The clips are held under tension so that when the bar is deployed, they snap snugly around the bar, releasing stored energy which assists in the bar's deployment. The trim (5) is further provided with an orifice (6) through which the pin can protrude on the deployment of the bar thereby enabling the pin (4) to contact the rear window (12) and to shatter the glass.Type: GrantFiled: October 26, 2005Date of Patent: April 3, 2007Assignee: Ford Global Technologies, LLCInventor: Martin Welch

Patent number: 7159901Abstract: An energy absorbing knee bolster for use in an interior of a vehicle is disclosed. An energy absorbing support structure is configured to support an instrument panel within a vehicle. The energy absorbing structure has a deployable tubular mechanism for absorbing occupant impact energy and an impact plate coupled to the tubular mechanism for absorbing occupant energy. An energy absorbing locking mechanism is disposed between the impact plate and the support structure. The locking mechanism is configured to encourage the collapse of the tubular means for absorbing energy in a telescopic fashion.Type: GrantFiled: June 10, 2003Date of Patent: January 9, 2007Assignee: General Motors CorporationInventors: Jenne-Tai Wang, Gary L Jones, Joseph D McCleary, Ching-Shan Cheng

Patent number: 7152881Abstract: An actuator of an active knee bolster is provided with a drive force generation device and a one way lock mechanism that is disposed in a vicinity of an operation end of the drive force generation device. The one way lock mechanism is configured such that, if attempted movement of a piston member in an inward insertion direction occurs, respective engagement portions are moved to a taper portion by urging force of a spring, whereby the engagement portions are abutted against an external periphery surface of the piston member such that the piston member and the engagement portions are fixed. Accordingly, as a result of the one way lock mechanism, a main body of the active knee bolster that has been moved to a restraining position cannot return in a vehicle forward direction, and thus it is possible to generate a substantial lower limb restraining force that restrains a lower limb of an occupant.Type: GrantFiled: February 20, 2004Date of Patent: December 26, 2006Assignees: Toyota Jidosha Kabushiki Kaisha, NHK Spring Co., Ltd.Inventors: Osamu Fukawatase, Takeaki Kato, Hiroyoshi Yamaguchi, Tadanori Hisamoto, Shinichi Horibata

Patent number: 7048298Abstract: A knee bolster for a vehicle has an air bag and an air bag inflator. The air bag has an inflated condition and a deflated condition. The air bag is attached to the knee bolster, which is moveable with the air bag. The knee bolster may move from an unactuated position when the air bag is in the deflated condition to an actuated position when the air bag is inflated. A guide structure, which is attached to the knee bolster directs the bolster along a linear path from the unactuated position to the actuated position.Type: GrantFiled: September 22, 2003Date of Patent: May 23, 2006Assignee: Key Safety Systems, Inc.Inventors: Robert Arwood, Eric Baumbach, Robert Block, John Cooper, Kaustubh Bedekar, Pat Atkinson

Patent number: 6994371Abstract: An occupant protection device for a motor vehicle occupant. The device includes an airbag arranged on a motor vehicle body in the region of a lateral roof edge of a motor vehicle, the airbag being configured to deploy downwards during inflation so that the inflated airbag extends in front of at least one side window of the motor vehicle; and a guide extending longitudinally and being connected to the lower edge of the airbag. The guide is movably guided on the motor vehicle body in the direction of deployment of the airbag.Type: GrantFiled: June 24, 2003Date of Patent: February 7, 2006Assignee: Takata CorporationInventors: Maximilian Bossecker, Ulrich Karlbauer, Robert Getz

Patent number: 6976706Abstract: An inflatable bolster system is provided for supporting a body portion of a vehicle occupant such as the knees and lower body or pelvis during a collision. The inflatable bolster includes a decorative substantially rigid front panel and an expandable metal rear panel attached to the non-metal decorative front panel. The inflatable bolster has an inflation orifice, and may have at least one vertical expansion fold and at least one horizontal expansion fold on the rear panel.Type: GrantFiled: February 6, 2003Date of Patent: December 20, 2005Assignee: Autoliv ASP, Inc.Inventors: Bradley W.

Patent number: 6971667Abstract: A glove compartment assembly incorporates a compact airbag module with a cushion constructed at least partially of a rigid material. The cushion may be sandwiched between front and rear door covers so that inflation of the cushion moves the front door cover toward the knees of a vehicle user to provide antisubmarining protection. The cushion may incorporate the front door cover as a portion of its inflation gas-containing membrane. The glove compartment assembly may utilize a uniquely designed latching system, such as an electric latching assembly, a latching assembly disposed generally off the door, or a break-away latching assembly disposed generally on the front door cover, to permit motion of the front door cover away from the instrument panel without interfering with the airbag module.Type: GrantFiled: January 14, 2003Date of Patent: December 6, 2005Assignee: Autoliv ASP, Inc.Inventors: Mark L. Enders, Bradley W. Smith
