| 20100308805 | TEMPERATURE TOLERANT MAGNETIC LINEAR DISPLACEMENT SENSOR - A linear motion sensor has two pairs of opposed spaced apart stacks of two simple two-pole bar magnets. Each stack has one shorter outer magnet and one longer inner magnet, with the outer magnets centered on the inner magnets. The poles of the magnets are oriented the same in each pair, but opposite with respect to the other pair. The shape of the magnets results in the magnetic fields produced by each pair of magnets being substantially outside of the magnets themselves, so that the load line for the combined magnets is above the knee in its B/H material demagnetization curve. The pairs of magnets define a gap therebetween in which a magnetic field sensor is mounted for travel. The shorter magnets are about one half the length of the longer magnets such that the magnetic field in the gap varies substantially linearly as the sensor moves along the gap. | 12-09-2010 |

| 20100127553 | VEHICLE SEAT - A vehicle seat has a seat base and a seatback. The vehicle seat has as a permanent feature a pair of seat belt guides positioned such that when a lap portion of a seat belt webbing is received in both of the seat belt guides the lap portion of the seat belt webbing intersects the seat belt guides at a selected distance from a forward face of the seatback. Each of the seat belt guides restricts movement of the lap portion of the seat belt webbing away from the forward face of the seatback. The seat belt guides direct the lap portion of the seat belt webbing across the seat base along a path such that the lap portion of the seat belt webbing interacts with the lower body of a child when the vehicle seat is occupied by a child aged three to twelve years and under 150 cm in height. | 05-27-2010 |
| 20100107371 | STRAP ANCHORING DEVICE - A device for anchoring a strap to a structural member has a strap and a strap anchoring member fixed to the strap at a first end of the strap. The strap anchoring member has a length and a width, wherein the length is greater than the width. The strap anchoring member is folded to provide only two layers of the strap anchoring member enclosing an end region of the strap adjacent a first end of the strap. A secured portion of the strap anchoring member is proximal the first end of the strap with both layers of the strap anchoring member fixed to the strap providing a three layer structure. An unsecured portion of the strap anchoring member is distal from the first end of the strap. A second end of the strap may be fixed to an airbag used for protecting an occupant of a motor vehicle. The positioning of the airbag when it is inflated can be achieved by having the strap extend through an aperture in a structural member of a motor vehicle with the strap anchoring device located on a side of the structural member distal from the airbag. The aperture has dimensions such that the unsecured portion of the strap anchoring member engages a surface of the structural member and impairs the passage of the strap anchoring device through the aperture toward the airbag. | 05-06-2010 |

| 20090020990 | VENTING DEVICE FOR AN AIRBAG INFLATOR - A device for supporting a rupturable closure member of a pressure vessel, such as an airbag inflator has a hollow support with a tapered portion and an adjoining cylindrical portion. An exterior surface of the tapered portion has longitudinally extending grooves therein. An igniter is located adjacent the cylindrical portion of the support and a pyrotechnic substance is located in the cylindrical portion of the support between the igniter and the tapered portion of the support. A rupturable closure member being forced against an open first end of the tapered portion of the support by the gas in the pressure vessel such that a chamber is formed within the support. The igniter when activated ignites the pyrotechnic substance and the burning pyrotechnic substance generates gas under pressure that causes the tapered portion of the support to break along the longitudinally extending grooves and no longer support the rupturable closure member allowing the gas in the pressure vessel to rupture the unsupported rupturable closure member. | 01-22-2009 |
| 20090020197 | GAS GENERATING COMPOSITIONS AND AIRBAG INFLATORS - Airbag inflators employ gas generating compositions formed from a mixture of fuels and a mixture of oxidizers and preferably mica at levels of 1 to 5% by weight. The gas generant composition contains a primary and secondary fuel. The primary fuel is a guanidine compound, preferably guanidine nitrate. The secondary fuel is selected from tetrazoles, triazoles and mixtures thereof at levels of 5% by weight or less of the total gas generant composition. The oxidizer system is a mixture of at least two components selected from the group consisting of transition metal oxides, alkali metal nitrates and alkaline earth metal nitrates. The novel gas generants yield inflating gases having a reduced content of undesirable gases such as nitrous oxides and carbon monoxide. | 01-22-2009 |
