  • SEAT BELT DEVICE
    Publication number: 20140217804
    Abstract: A seatbelt device for a vehicle. The seatbelt device includes a seatbelt connected at a first end to retractor and connected at a second end to a belt position changing member, which is movable between forward and rearward positions relative to the vehicle. The second end of the seatbelt is connected to the belt position changing member such that the position of the second end of the seatbelt changes relative to the belt position changing member, as the belt position changing member is moved from the rearward position to the forward position, thereby preventing the webbing of the seatbelt from twisting and inverting of the tongue plate upon activation of the belt position changing member, the latter which makes the tongue the plate difficult for an occupant to reach.

  • Pyrotechnic gas generator with combustion and diffusion chambers of different sections
    Patent number: 8794666
    Abstract: A pyrotechnic gas generator intended for motor-vehicle safety includes a combustion chamber of cylindrical or approximately cylindrical shape. An initiator is located within the combustion chamber and is associated with at least one solid pyrotechnic charge. A diffusion chamber communicates with the combustion chamber and receives gases generated by the pyrotechnic charge and transfers the gases to atmosphere via at least one evacuation opening. The diffusion chamber extends parallel to the longitudinal axis of the combustion chamber, in the extension of one of its end faces. The diffusion chamber is also of generally cylindrical or approximately cylindrical shape, but with a cross section that is less than that of the combustion chamber. The diffusion chamber is devoid of structure for filtering the gases that pass therethrough.
