Patent number: 7322602Abstract: A horn switch device includes a retractable body, an unmoving body, first and second biasing members for biasing the retractable body in a restoring direction, and first and second contact members. The contact members are attached to, and move with, the retractable body, and are capable of contacting each other by movement of the retractable body. The first biasing member pushes the first contact member and the second contact member apart. The second biasing member pushes the second contact member toward the first contact member. When a module cover is depressed, the biasing members are compressed to bring the contact members into contact with each other, thereby sounding the horn. Since the biasing members are arranged in series, vehicle vibration can be absorbed, thereby preventing accidental contact of the contact members. The device facilitates positioning of the contact members, thereby simplifying assembly of a steering wheel and an airbag system.Type: GrantFiled: November 21, 2005Date of Patent: January 29, 2008Assignee: Takata CorporationInventors: Kei Tsujimoto, Wataru Nakazawa

Patent number: 6402193Abstract: The invention relates to a steering wheel, in particular for use in motor vehicles. The steering wheel comprises a steering wheel plane, an airbag module, a support plate and a spring plate connected to the support plate via an electrically insulating element. The steering wheel further comprises an insulating support fixed to the steering wheel, and restoring springs for replacing the airbag module in an initial position after displacement for actuation of a horn contact. The airbag module, for actuation of the horn contact, is constructed so as to be displaceable approximately perpendicularly to the steering wheel plane against the restoring springs by at least a contact gap.Type: GrantFiled: April 7, 2000Date of Patent: June 11, 2002Assignee: TRW Automotive Safety Systems GmbH & Co.

Patent number: 6364344Abstract: A steering wheel airbag assembly (1) for a motor vehicle with a driver airbag module (2), in which the module snaps into an aligned engagement with the steering wheel during manufacture of the steering wheel. The assembly (1) includes an airbag supporting portion (4) with a plurality of apertures therein (21,31,41) and a driver airbag module (2) attached to the supporting portion (4) and having a plurality of legs (14,15,16), each of which extends slidingly into a corresponding aperture (21,31,41) being movable towards and away from the supporting portion (4). Engagement barbs (24) between each leg (14,15,16) and aperture (21,31,41) limits said movement and keeps the module (2) and supporting portion (4) attached. A spring (19) between the module (2) and the supporting portion (4) spring biases the module away from the supporting portion (4).Type: GrantFiled: January 5, 2001Date of Patent: April 2, 2002Assignee: Ford Global Technologies, Inc.Inventors: Ray Hudd, Ray Trebes, Tim Scott

Patent number: 6365853Abstract: A device for closing an electrical switch, for installation in a steering wheel of a motor vehicle is disclosed. The switch has a first contact element (1) which is essentially fixed, a second contact element (2) moveable against a return force, and an actuating means (6). The contact elements (1, 2) consist of elongated wire shaped or strip shaped material sections which are held parallel to one another within a spacer cage (3) at a defined distance from each other. Sections (4) of the cage (3) with fixed distance between the contact elements alternate, as seen in a longitudinal direction, with sections (5) where the second contact element (2) can be pressed against the first contact element (1) by means of the actuating means (6), accompanied by an elastic deformation of the material section of the second contact element (2).Type: GrantFiled: July 23, 1999Date of Patent: April 2, 2002Assignee: TRW Automotive Safety Systems GmbH & Co. KGInventor: Ralph Frisch

Patent number: 6312012Abstract: A steering wheel has a skeleton with a foamed sheathing, a hub, spokes and a steering wheel rim. A gas bag module is inserted in a central recess of the steering wheel. The gas bag module has a cover cap at the side facing the driver. For actuating a horn switch the module is movable in the direction of the steering wheel axis relative to the steering wheel. A movement gap is formed between the cover cap and the foamed sheathing. Mounting studs on the skeleton extend parallel to the steering wheel axis. The positioning of the mounting studs is defined by the foamed sheathing. The mounting studs have free ends which are slidingly accommodated in guide recesses provided in the cover cap.Type: GrantFiled: March 19, 1999Date of Patent: November 6, 2001Assignee: TRW Automotive Safety Systems GmbH & Co. KGInventors: Stephan Bohn, Ralph Frisch

Patent number: 6299201Abstract: There is disclosed an automotive steering wheel W1 including a heavy air bag system 30. This air bag system 30 is held by a horn-switching mechanism 40. Although the air bag system 30 is heavy, the operator has a good feel for the operation of the horn-switching mechanism 40. This horn-switching mechanism 40 comprises a stationary member 41, a movable member 48, a switch main body 50, coil springs 55, and a jawed bolt 56. The switch main body 50 comprises a stationary contact 52 mounted on the stationary member 41 and a movable contact 54 mounted on the movable member 48. The coil springs 55 bias the movable member 48 upward. The jawed bolt 56 permits the movable member 48 to be moved toward the stationary member 41 and limits the distance of the movable member 48 from the stationary member 41. At least one of the coil springs 55 is located at a height substantially equal to the height of the resultant center of gravity G of all components biased upward by all the coil springs 55.Type: GrantFiled: September 12, 2000Date of Patent: October 9, 2001Assignee: Toyoda Gosei Co., Ltd.Inventor: Yoshiyuki Fujita

Patent number: 6260876Abstract: A snap-on thermoplastic air bag cover mountable onto an air bag container assembly includes a novel mechanism for attaching a horn backing plate to the cover. The assembly includes a container having a retaining member and a retaining bracket. The cover includes a front panel having inner and outer surfaces and is adapted to overlie an uninflated air bag contained within the container. The cover also includes a plurality of side walls connected to and extending rearwardly from the inner surface of the front panel, a horn switch lying behind the inner surface of the front panel, and a plurality of locking blocks having an extending snap-on groove and which are connected to their respective side walls. Two of the locking blocks have a groove defined in rearwardly facing surfaces thereof. The cover also includes a backing section with a back plate cooperating with the front panel to form a hollow compartment for the switch. The switch is activated by depression of the front panel at its outer surface.Type: GrantFiled: January 21, 2000Date of Patent: July 17, 2001Assignee: Patent Holding CompanyInventors: Michael G.
