Patent number: 6871874Abstract: An airbag module utilizes tape dispensing cartridges. A tape end extends from each cartridge to the inside surface of an airbag. As the airbag inflates, tape is drawn from the tape cartridges as the tapes are drawn along with the deploying airbag. The rate at which tape is withdrawn from the cartridges is measured by sensible indicia of a magnetic or optical nature positioned on the tape and drawn past a sensor contained within the tape cartridge. The markings on the tape can be nonuniform along the length of the tape. The tape storage area outlet and the cartridge outlet are each formed by two relatively large radius corners. The tape is sealed to the cartridge to prevent the ingress of contaminants. As the airbag withdraws tape from the cartridges, the seals are unseated.Type: GrantFiled: December 18, 2002Date of Patent: March 29, 2005Assignee: Key Safety Systems, Inc.Inventors: Harald S. Husby, John Fisher, Brian Ford, Joel Jerrim, Rolf Sawall

Publication number: 20040183289Abstract: An airbag deployment sensor stores a quantity of tape which is drawn out of a cartridge during airbag deployment by one end of the tape which is attached to the inside surface of an airbag. To facilitate assembly of an airbag system, the cartridge is designed with a key for locking the tape against premature extraction from the cartridge during the assembly process. The cartridge is used in combination with a mounting bracket which assures that the tape is free to be extracted from the cartridge once the cartridge is mounted to the bracket because, either the cartridge cannot be mounted to the bracket with the key in place, or the mounting bracket causes the key to move to a non-locking position.Type: ApplicationFiled: March 20, 2003Publication date: September 23, 2004Inventor: Harald S. Husby

Patent number: 6282942Abstract: A crash sensor comprising a magnetic field sensor with means for concentrating magnetic flux from the magnet, wherein the magnetic field sensor detects a change in magnetic field strength as the sensing mass moves causing a corresponding change in output voltage or current from the magnetic field sensor. The magnetic field sensor is used for determining crash severity for timely deployment of an occupant restraint system.Type: GrantFiled: January 19, 2000Date of Patent: September 4, 2001Assignee: Breed Automotive Technology, Inc.Inventor: Harald S. Husby

Patent number: 5237134Abstract: Conventional ball-in-tube, gas-damped, crash sensors utilize a gold plated ball to bridge two contacts. When the ball senses acceleration (deceleration) in the longitudinal direction of a cylinder of sufficient magnitude and duration, it moves to where it bridges the contacts, completing the electrical circuit and initiating deployment of a safety restraint system. A switch activated by magnetic flux is combined with this type of gas-damped sensor to provide a solid and reliable contact duration and ensure the correct functioning of the sensor. The level of biasing force for crash zone crash sensors of this type has been increased to avoid late firing problems on marginal crashes.Type: GrantFiled: December 28, 1990Date of Patent: August 17, 1993Assignee: Breed Automotive Technology, Inc.Inventors: Torbjorn Thuen, Harald S. Husby, Allen K. Breed

Patent number: 5153392Abstract: An accelerometer for sensing velocity changes particularly suited for passenger restraint systems in a motor vehicle for the deployment of an air bag includes a housing with a magnetic closing element. The magnetic closing element includes a permanent magnet which generates a field around the sensor housing. A restricting element is mounted around the magnet for restricting and concentrating the magnetic field around the sensor. In an alternate embodiment, two similar sensors may be housed in a single enclosure for additional sensitivity. The restrictive elements of the sensors eliminate interference between the sensor magnetic fields.Type: GrantFiled: March 12, 1991Date of Patent: October 6, 1992Assignee: Breed Automotive Technology, Inc.Inventors: Harald S. Husby, Allen K. Breed, Ted Thuen

Patent number: 5031931Abstract: An accelerometer for a passenger restrain system in a motor vehicle includes a housing with a path for an inertial element, and spring members for urging the inertial element toward a preselected position. When the vehicle decelerates at a rate higher than a preset rate, the ball moves away from the preselected position and closes an electrical contact. A closed chamber may be used as a dampening element for the inertial element.Type: GrantFiled: December 6, 1989Date of Patent: July 16, 1991Assignee: Breed Automotive CorporationInventors: Torbjorn Thuen, Harald S. Husby, Allen K. Breed

Patent number: 5011182Abstract: An accelerometer for sensing velocity changes particularly suited for passenger restraint systems in a motor vehicle for the deployment of an air bag includes a housing with contact blades and a contacting element. The contacting element is arranged to move toward the contact blades when a deceleration exceeding a threshold level is sensed. A retaining element is provided to set the blades in a preselected position so that the blades are contacted by the contacting element simultaneously thereby improving the response time of the accelerometer.Type: GrantFiled: October 6, 1989Date of Patent: April 30, 1991Assignee: Breed Automotive Technology, Inc.Inventors: Harald S. Husby, Allen K. Breed, Ted Thuen

Patent number: 3973092Abstract: Acceleration sensing apparatus comprises a casing having a pair of substantially perpendicular passages communicating with each other and accommodating spaced apart, normally open electrical contacts. One of the passages contains mercury which is operable to flow into the other passage in response to predetermined acceleration of the casing and bridge the conductors so as to establish a current path therebetween.Type: GrantFiled: March 22, 1974Date of Patent: August 3, 1976Assignee: Breed CorporationInventors: David S. Breed, Harald S. Husby, Stanley Sung
