The invention relates to a gas bag module comprising a gas bag which has a gas bag wall with a front wall section. The module further comprises a cover which has a given annular section which closes an annular outlet opening for the gas bag and has a stationary central portion which is surrounded by the annular section. A section of the gas bag wall other than the front section has an outflow opening which in a folded state of the gas bag is arranged beneath the central portion in such a manner that on outlet of the gas bag, the central portion arrives via the outflow opening into an interior of the gas bag.

Gas bag module

An air bag module, comprising: a housing having at least one vent opening; an inflatable cushion being stored in an un-deployed position in the housing; an inflator for inflating the inflatable cushion, the inflator being in fluid communication with the inflatable cushion and having a plurality of inflation openings for allowing an inflation gas to pass therethrough, at least one of the plurality of inflation openings being in fluid communication with the at least one vent opening; a deployable member being secured to an interior surface of the inflatable cushion at one end and a portion of the airbag module at the other end; wherein the deployable member is configured to allow venting through the at least one vent opening when the inflatable cushion is in the un-deployed position and the at least one vent opening is covered by the deployable member when the inflatable cushion inflates towards a fully deployed position.

Apparatus and method for controlling an inflatable cushion

A tethered knee bolster panel which is deployed rearward in the passenger compartment of an automotive vehicle during a crash to provide lower torso restraint. The knee bolster is an air bag system which propels the knee bolster panel rearward during deployment. The activated knee bolster allows automobile designers the flexibility to provide increased leg room in the vehicle while maintaining the same level of safety during a crash.

An occupant restraint system (10), and an associated control method, for a vehicle (16). The system (10) includes an actuatable occupant restraint device (18) which has an adjustable aspect. An ultrasound sensor (34) senses an occupant condition at a sense rate and provides a signal (38) indicative of the sensed occupant condition. An ultrasound signal sampler function (46) of a controller (26) samples the signal (38) at a sample rate. A restraint control determination function (50) of the controller (26) makes determinations regarding control of the restraint device (18) at a determination rate using the signal samples. A weight sensor (56) and at least one seat belt sensor (58, 60) sense occupant conditions (e.g., occupant weight and seat belt status) and provide indicative signals (66, 68, 70) to a rates determination function (84) of the controller (26). The rates determination function (84) determines the sense, sample and determination rates in response to the sensed occupant conditions.

An air bag (32) adapted to be inflated comprising: an inlet portion (36) to receive inflation gas and a flexible walled portion (34,40) including at least one first vent hole (42) therein; a flexible member (50), joined at one end thereof to the walled portion on one side of the first vent hole and at another end thereof to the walled portion on an opposite side of the first vent hole, the flexible member including at least a second vent hole, expansion joints (60,70,62,72), formed in the flexible member and the walled portion for maintaining the first and second vent holes aligned during an initial phase of inflation so as to provide exhaust port (44) through which inflation gas may exit and for permitting the first and second holes to move relatively to one another during continued inflation so as to close of the exhaust port.

An anti-collision cushion is disclosed for the occupants of a motor vehicle. Known anti-collision cushions are constructed with a central part which is connected to two side parts of equal size. A tearing fold which reduces the volume capacity, and which is formed by a rip seam, is provided on the surface of the central part. In the deployment phase an expansion occurs with high velocities in the region of the side parts, which may result in injuries to the occupant in some circumstances. In the novel anti-collision cushion the rip seams connect the connecting seams which are contiguous in the region of the tearing fold between the central part and the side parts. A reduction of the expansion and of the expansion velocity, particularly in the region of the side parts, is thereby achieved.

An impact protection device for an occupant of a motor vehicle having an air bag. The air bag is arranged folded up in a receptacle fixed to the vehicle and can be inflated by a filler gas. An air bag surface facing a vehicle occupant being limited in its movement towards the vehicle occupant in the center region by a restraining device. The restraining device is formed by a cover plate over the receptacle which is connected to the vehicle by short limiting straps, so that on unfolding the air bag extends around the periphery and in the direction of the vehicle occupant in front of the cover plate.

The invention relates to a restraining system for occupants of a motor vehicle. The occupant is safeguarded by a safety belt and an airbag. So that the inflation pressure of the airbag can be controlled according to whether the occupant is strapped in or not, the gas generator of the airbag possesses a heater which switches on when the belt is not fastened and which is intended for increasing the inflation pressure which can be generated.

Restraining system for occupants of a motor vehicle

Impact protection devices, arranged in steering wheels or dashboards of motor vehicles, for vehicle occupants are provided with covers which open in the event of an accident in order to release an inflating air bag of the protection device. The cover, which consists of at least one cover flap, is injection molded onto a carrier part by a tough elastic plastic. The plastic surround has along an edge, intended as pivot axis, of the cover flap a cross-sectional tapering which serves as a hinge. At the other edges, the plastic surround is constructed towards the corresponding edges of the carrier part as a groove which, in the event of pressure on the cover flap in the opening direction, easily releases the carrier part edge.

The panel is attached to the trim by tags (10) joined to the trim by small bridges of plastics. The tags are outside the opening profile of the panel. The cover is also attached to the dashboard mounting by a flexible tie to prevent being thrown into the face of the passenger when the airbag is operated. The panel is moulded with the dashboard trim in one operation. Simple cuts (11) define the cover and tags. ADVANTAGE - The released panel leaves no protruding tags to damage the expanding airbag and is moulded with the dashboard trim in one operation.
