  • Patent number: 11974123
    Abstract: A motor vehicle stores a first one-way hash of a password and an encrypted value from a second one-way hash of the password. A method for authenticating a device with respect to the vehicle includes the following: a PACE procedure is carried out so that the device and the motor vehicle determine the same session key; the motor vehicle generates a communication key on the basis of the session key and the encrypted one-way hash; and the device generates the communication key based on the session key and the second one-way hash.

  • Patent number: 9500223
    Abstract: A bearing assembly for a transmission of a vehicle, including: a gearwheel; a gearshaft; and a double-row, asymmetrical tapered roller bearing between the gearwheel and the gearshaft, in an O arrangement and including a first row of tapered rollers, which adjoins a shaft end and a second row of tapered rollers, which adjoins the first row of tapered rollers. The first and second rows of tapered rollers are arranged between a shared outer ring arranged on the gearwheel and separate, dedicated inner rings arranged on the gearshaft. A first acute contact angle on the first row of tapered rollers is not equal to a second acute contact angle on the second row of tapered rollers. The first contact angle is at least 3° less than the second contact angle. A difference between the second contact angle and the first contact angle is at most 10°.

  • Patent number: 7497469
    Abstract: An airbag (10) for a vehicle occupant restraint system includes an airbag wall (14) having a gas outlet opening (26), and a control strap (16) extending through an interior of the airbag along an airbag depth (y) that is defined by a distance between two airbag wall areas (27, 28), the airbag wall areas (27, 28) being situated opposite to each other and the airbag wall areas (27, 28) being joined to one another by the control strap (16). A wall section (20) is turned one of inside and outside relative to the inflated airbag (10), depending on the airbag depth (y), such that, in response to a displacement of the control strap (16), the airbag (10) can be moved from a first outer contour, in which the airbag depth (y) is large and the wall section (20) is turned into the interior of the airbag, to a second outer contour, in which the airbag depth (y) is smaller and the wall section (20) is turned outside.

  • Patent number: 7152876
    Abstract: A gas bag for a side impact protection device includes at least two inflatable chambers (28, 30) separated from each other in a gas-tight manner. The gas bag (10) is formed from two covering layers (12, 14) lying one over the other, which define an inflatable region and an inflation opening (16) of the gas bag (10), and from a fabric layer (18) arranged between the two covering layers (12, 14). The fabric layer (18) has an outer edge which in the inflatable region of the gas bag (10) is connected only with one of the two covering layers (12, 14) to divide the gas bag (10) into the two chambers (28, 30).
