  • Publication number: 20240133458
    Abstract: A ventilation module for a transmission of a motor vehicle, in particular an electrically driven motor vehicle, comprises a housing with a connection opening on the transmission side and an atmosphere opening open to the environment, wherein a gas channel connecting the connection opening to the atmosphere opening in a gas-conducting manner is provided in the housing. A float valve with a float arranged in a float chamber, a valve body and a valve opening is arranged in the gas channel, wherein liquid entering the float chamber through the atmosphere opening causes the float to rise, wherein when a certain liquid level in the float chamber is exceeded the float, the valve body connected to the float, closes the valve opening and thereby the gas channel in a liquid-tight manner.

  • Patent number: 10053048
    Abstract: An airbag unit having an airbag and at least one inflator. The airbag unit is especially suitable for preventing an element located outside the passenger compartment of a vehicle from intruding into the passenger compartment during an accident. The airbag is made of a hose formed of a one-pieced woven element extending from a first end to a second end. The hose is bent or folded, such that two parallel sections (24a, 24b) of the airbag are formed with each section (24a, 24b) enclosing a chamber. The airbag is very robust and can be designed such that in its deployed state its thickness is large in relation to its volume.
