A gas bag for a vehicular occupant restraint system comprises a wall defining an interior space of the gas bag intended to be filled with pressurized gas. A plurality of curved nicks is provided in the wall of the gas bag. Each of the curved nicks determines an emission orifice for the pressurized gas.
Abstract:
A gas bag for a vehicle occupant restraining system, which is adapted to be unfolded from a folded state into a deployed state by gases led into the interior of the gas bag, comprises at least one fabric part having edges which are connected together along at least a part of their length by a seam. This seam is formed by a plurality of stitches and at least one thread. The length of the stitches and the tension of the thread is so set that, in the deployed state of the gas bag, a plurality of discharge openings are formed between respectively adjacent stitches between two edges sewn together. A controlled discharge of the gases takes place through the discharge openings.

Abstract:
The invention relates to a heat exchanger plate for an evaporator; with a longitudinal axis and a transverse axis, with the transverse axis being disposed perpendicularly or substantially perpendicularly to the longitudinal axis; with at least one flow channel which extends in the direction of the longitudinal axis of the heat exchanger plate through a heat supply area of the heat exchanger plate and conducts the medium to be evaporated; with an inlet for the medium to be evaporated, which inlet is in a flow-conducting connection with the at least one flow channel arranged in the direction of the longitudinal axis of the heat exchanger plate, with a meandering inflow channel being provided in the direction of the longitudinal axis between the inlet and the at least one flow channel arranged in the direction of the longitudinal axis, which inflow channel is in a flow-conducting connection with the inlet and the at least one flow channel, and conducts the medium which flows out of the inlet to the at least one flow channel in an alternating manner along the transverse axis in the direction of the at least one flow channel. The invention is characterized in that the meandering inflow channel is formed by a plurality of webs which are disposed on the heat exchanger plate or a base plate which forms the bottom or top of the inflow channel and the at least one flow channel arranged in the direction of the longitudinal axis, which webs extend in the direction of the transverse axis, and the inflow channel between the webs is subdivided into individual partial channels by a plurality of plates which extend in the direction of the transverse axis.
Abstract:
The invention is characterised in that the expander is integrated into the secondary side of the transmission by means of one or more of the following features: the expander has a housing which substantially completely surrounds the expander; the expander is equipped with a drive shaft which projects out of the housing and has a coupling element that is fixed to the drive shaft and that produces a drive connection. The housing of the expander is mounted on the secondary side on the exterior of a transmission housing that surrounds the transmission, or is mounted from the exterior and partially inserted into the transmission housing, in such a way that the coupling element of the drive shaft projects into the transmission housing, producing a direct or indirect drive connection to the transmission output; the transmission has a heat exchanger, which is used to cool transmission oil for lubricating the transmission and/or actuating clutches or brakes inside the transmission, the working medium of the expander being conducted through the heat exchanger in such a way that heat is dissipated from the working medium to partially or completely condense the latter or that heat in the heat exchanger is transferred to the working medium of the expander to heat the latter.
