Patent number: 6712388Abstract: A hybrid gas generator comprises an elongated cylindrical outer housing, and a pressure chamber that is filled with pressurized gas and that is closed off by a membrane provided on an end face of the pressure chamber. The gas generator further comprises a pyrotechnical propellant charge that is provided for opening the membrane and is accommodated in a preferably bushing-shaped propellant charge housing. The propellant charge housing is connected to the outer housing at a location outside of the pressure chamber and a longitudinal axis of the propellant charge housing extends at a right angle to a longitudinal axis of the outer housing. The generator also has an axial outflow opening situated at one axial end of the outer housing. The outer housing has a circumferential wall with a radial insertion opening for introducing the propellant charge housing.Type: GrantFiled: September 5, 2002Date of Patent: March 30, 2004Assignee: TRW Airbag Systems GmbH & Co.

Patent number: 5248283Abstract: A vehicle transmission has two shafts parallel to one another. At least one of the shafts is formed of two partial shafts which are in alignment and axially spaced apart. A torsion shaft then connects the two for rotation with each other, but prevents transmission of bending moments between the partial shafts. This structure is particularly useful in a hydrostatic-mechanical power distributing transmission, in which the torsion shaft is radially aligned with the planetary gearsets of the power distributing transmission. The torsion shaft can be considerably thinner than the comparable portion of a conventional shaft, so the overall transmission can be more compact radially. The transmission also is provided with unequal gear ratios, while the planetary gearsets are the same size, allowing a particularly compact structure. Preferably, one of the gear ratios with a small control ratio is used as the primary working range for the transmission to maximize efficiency.Type: GrantFiled: May 11, 1992Date of Patent: September 28, 1993Assignee: Deere & CompanyInventors: Uli Eckhardt, Anja Esau
