Abstract: A vehicle crush detecting device including an electrically conducting tube with an electrically conducting rod positioned within the tube along with insulators positioned at least two points between the rod and tube to insulate the rod from the tube. The electrically conducting tube is deformed during a vehicle crash causing the tube to contact the rod in response to crush of the vehicle. A header/connector assembly seals a space between the rod and tube at one end while a space between the rod and tube at the opposite end is closed. The header/connector assembly includes electrical connector pins electrically coupled to the rod and tube and having an exposed portion for connection to a wire harness. The device is used to sense crashes for the deployment of automobile passive restraint systems such as airbags.

The control units include a power supply for enabling operation of the initiator.

Abstract: An airbag for a vehicle formed from sections of material joined to one another, e.g., heat-sealed or adhesively-sealed, such that interconnected compartments receivable of an inflating medium are formed. The sections of material may be fabric or discrete sheets of film with optional tear propagation arresting devices. Two or more of the sections of material may be at least partially in opposed relationship to one another and then joined to one another at locations other than at a periphery of any of the sections to thereby form the interconnected compartments between the sections of material. The sections of material may also be joined to one another along parallel lines such that the interconnected compartments formed between the sections of material are elongate, i.e., substantially straight, and when inflated will be tubular.

The electrically conducting tube is deformed during a vehicle crash causing the tube to contact the rod in response to crush of the vehicle. A header/connector assembly seals a space between the rod and tube at one end while a space between the rod and tube at the opposite end is closed. The header/connector assembly includes electrical connector pins electrically coupled to the rod and tube and having an exposed portion for connection to a wire harness. The device is used to sense crashes for the deployment of automobile passive restraint systems such as airbags.

Abstract: A vehicle crush detecting device including an electrically conducting tube with an electrically conducting rod concentrically positioned within the tube along with insulating means positioned at at least two points between the rod and the tube to insulate the rod from the tube. The electrically conducting tube is deformed during a vehicle crash by a force greater than a predetermined magnitude which causes the tube to contact the rod in response to the crush of a vehicle. The crush sensor is mounted at the rear boundary of the Crush Sensor Zone of the vehicle for frontal and rear impacts and in the door or other appropriate side position for side. The sensor is used to sense crashes for the deployment of automobile passive restraint systems such as airbags.

Abstract: An airbag deployment system including at least one module housing, at least one deployable airbag associated with each housing, an inflator associated with each housing for inflating the airbag(s) to deploy into the passenger compartment, an airbag inflation determination unit for determining that deployment of the airbag(s) is/are desired, and respective electronic control units arranged within or proximate each housing and coupled to a respective inflator and the airbag inflation determination unit for initiating the inflator to inflate the airbag(s) in the respective housing upon receiving a signal from the airbag inflation determination unit. The control units include a power supply for enabling initiation of the inflator.

Abstract: An inflatable occupant restraint module including a housing mounted in the vehicle and having an interior, a deployable airbag contained within the housing interior prior to deployment, an inflator coupled to the housing for inflating the airbag by supplying a gas into the airbag interior and an initiator for initiating the supply of gas into the airbag interior in response to a crash of the vehicle. The airbag includes at least one non-perforated sheet of film defining the airbag interior and a thermoplastic elastomeric material arranged at specific locations in connection with the sheet(s) of film such that the locations are thicker in comparison to an average thickness of the sheet(s) of film.

Abstract: An infinite door check mechanism for enabling a door to be moved from a closed position in a door frame to any one of a plurality of different open positions including a clevis adapted to be mounted to the frame, an elongate strip member mounted to the clevis and directed outward from the frame, a door check housing adapted to be mounted on the door, the strip member extending at least partially through the housing, and a support member arranged in the housing. A movable locking member is arranged in the housing such that the strip member is interposed between the locking member and the support member. A biasing member such as a spring is positioned in the housing for selectively pressing the locking member against the strip member to force the strip member against the support member and thereby retain the strip member in a fixed position and releasing pressure of the locking member against the strip member and thereby enable movement of the strip member.

Abstract: An inflatable occupant restraint device in an occupant protection system of a vehicle including a housing mounted in the vehicle and having an interior, at least one deployable airbag contained within the housing interior prior to deployment, an inflator coupled to the housing for inflating the airbag, the airbag being attached to and in fluid communication with the inflator, and an initiator for initiating a gas supply mechanism in the inflator to supply gas into the interior of the airbag in response to a crash of the vehicle. The airbag is made of a first non-perforated sheet of film and a member arranged in connection with the film sheet for arresting the propagation of a tear in the film sheet.

Abstract: An inflatable occupant restraint device in an occupant protection system of a vehicle having at least two pieces of substantially flat inelastic plastic film having peripheral edges attached together only at their peripheral edges to form a substantially sealed airbag, an inflator coupled to the airbag and to the vehicle for inflating the airbag by providing gas to the airbag through at least one port in one of the pieces of elastic film, and an initiator for initiating the inflator in response to a crash of the vehicle. Upon inflation of the airbag, the at least two pieces of inelastic plastic film deform substantially without stretching, in particular to create a shape for the airbag where the thickness is substantially smaller than the width or height and/or to provide the airbag with an ellipsoidal shape.
