  • Patent number: 7309935
    Abstract: The present invention relates to a fan wheel (11) for electrical machines, in particular for alternators of motor vehicles, with a fan disk (10) that, on its axially outwardly directed end face, has a number of fan blades (13, 18) distributed around the circumference in the shape of a circular ring, the fan blades extending away from the fan disk in the axial direction, so that cooling air beneath the fan blades can be drawn in axially and blown radially outwardly between air channels (20, 21) formed between them. One part (18) of each of the fan blades is joined in a fixed manner with the fan disk (10) via only its radially outward end section (18a), so that each inner end section (18b) is swiveled radially increasingly outwardly by a centrifugal force (22) occurring there as rotational speeds increase, to reduce the cooling air stream.

  • Patent number: 7246819
    Abstract: An airbag module for a vehicle occupant restraint system includes an airbag (22) and a gas generator (10) that is connected via at least one first outflow opening (18) to an airbag chamber (28), the airbag chamber (28) being at least partially formed by the interior of the airbag (22), an actuator unit (36) being provided on the gas generator (10) and, when the actuator unit (36) is activated, it releases a traction element (50) that causes a pressure reduction in the airbag (22), an activation of the actuator unit (36) also leading to an opening of a second outflow opening (20) in the gas generator (10), which vents generator gas to an environment without this vented gas flowing into the airbag chamber (28). Moreover, the invention relates to a method of restraining a vehicle occupant with such an airbag module.

  • Publication number: 20060261583
    Abstract: Pyrotechnical fuel contained in a gas generator of an airbag module accommodated in a module housing self-ignites at a predetermined temperature elevated above normal ambient temperatures. A module housing of the airbag module has a wall section with a predetermined opening closed with respect to gas flow at normal ambient temperatures. The gas generator has at least a first outflow opening and a second outflow opening, the second outflow opening being closed when the gas generator is actuated at normal ambient temperatures. The wall section of the module housing is designed in such a way that on self-ignition of the pyrotechnical fuel at at least the predetermines temperature, the predetermined opening is created in the wall section, and the second outflow opening is opened with respect to gas flow by creation of the predetermined opening.

  • Publication number: 20040080146
    Abstract: An airbag module (10; 110) for a vehicle occupant restraint system comprises a gas lance (22; 122) that can feed gas from a source of compressed gas (40; 140) into an airbag (20; 120), and a housing (12; 112) which accommodates the gas lance. The gas lance (22; 122) has a connection extension (36; 136) for being connected to the source of compressed gas (40; 140). The connection extension (36; 136) projects so far out of the housing (12; 112) that it can penetrate into the source of compressed gas (40; 140) installed outside of the housing. The connection extension serves to supply the gas lance (22; 122) with compressed gas from the source of compressed gas (40; 140) as well as to mechanically attach the source of compressed gas (40; 140) to the airbag module (10; 110).
