Abstract:
A safety device for a vehicle seat is in the form of a lap strap (2) having a folded inflatable air-bag (7) secured to the strap extending from one of the strap. On inflation, part of the inflated bag will extend towards the other end of the lap strap. The location of the folded air-bag is such that the folded air-bag will not engage means releasably connected to a buckle even when the lap strap is buckled and extends tightly across the seat without an occupant in the seat.
Abstract:
The invention relates to a textile construction for using in passenger restraint systems. Said textile construction is characterised in that it contains plastically deformable filaments which enable the surface of the textile construction to increase when pressure is applied in at least one surface direction. The inventive textile construction is also provided with an especially elastic coating.
Abstract:
The invention relates to a restraint system comprising at least one belt tightener system. Said restraint system is designed for a safety belt for a vehicle passenger and is characterised in that at least one of the belt articulation or reversing points can be displaced by means of the belt tightener system. The invention also relates to a control device that can be operated by a pyrotechnic propelling charge and is actively connected to the articulation or reversing point. In order to improve the vehicle passenger safety, said belt tightener system (4, 24, 27, 33, 34) is placed in a gastight chamber in fluid communication with an inflatable restraint device.
Abstract:
An inflatable belt system and a method of operation for a vehicle occupant restraint in which a lap belt section or torso belt section, or both, have dual load bearing portions (31, 32) with an inner portion (31) being inflatable. During inflation of the inner portion (31) the other outer belt portion (32) ruptures along a selected weakened line or area (361).
Abstract:
A seat restraint system (110) whose torso belt (101t) includes an inflatable structure (101) that inflates upon impact to protect the occupants of a vehicle such as an automobile. The inflatable structure is linked to a gas generator (122) and crash sensor. When an impact above a predetermined level of severity is detected, the gas generator is ignited, inflating the inflatable structure which contracts in length as it inflates. In a preferred embodiment, the inflatable structure is a braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube. The contraction in length pretensions the seat belt system by pulling any slack out of the seat belts system.
Abstract:
This invention relates to a safety belt for fastening a person in a chair of a vehicle, which chair has such a construction that the attachment of the back of the chair of the vehicle when loaded more than to a certain level can collapse, whereby the back of the chair can move backwards in relation to the vehicle, the safety belt in a conventional way being a multipoint belt comprising a portion which is intended to be in contact with the stomach of the person. According to the invention the safety belt is characterized by the fact that the mentioned portion of the belt has the ability to apply a force against the stomach of the person that is greater than normally, which in combination with the ability of the back of the chair of the vehicle to be displaced backwards forces the person in question backwards in relation to the vehicle.
Abstract:
The invention relates to a safety device (12), comprising a seat belt (14) with a strap (16), an intermediate part (32, 34) of which can be in a stored position and in an operating position in which it extends along a part of the body of the passenger, and a bag (40) which can be inflated to hold back a passenger in case of collision. The bag is held by a support (42) which can be moved between a stored position and an operating position in which the support (42) and the inflated bag (40) extend along a part of the body of the passenger. The invention is characterized in that the support (42) of the inflatable bag (40) is embodied as a flexible strip which is independent of the strap (16) of the seat belt (14) and an intermediate part of which extends along a part of the body of the passenger when the airbag is in the operating position.
Abstract:
An inflatable band occupant restraint system includes an inflatable band that is configured to lower the stresses encountered by the band fabric during inflation and secondary impact. This reduction is accomplished by including a pleat pattern that better approximates the ideal cylindrical curvature of the band when inflated, attaching the band to a seat belt using a smaller radius attachment portion, and stitching the pleated portion of the band to the belt while maintaining the center of the band stitching-free.
Abstract:
The invention relates to a weaving method for producing a length of fabric which has a variable width. According to the inventive weaving method, the sheet of warp is guided in the area of the shed with a space between the warp ends which is enlarged or reduced according to the desired width of the fabric. The fabric is guided by a temple expander (19) at least on both of its longitudinal edges and preferably directly after the stroke of the weft yarn. The effect of the temple expanders on the width of the fabric is controlled synchronously with and substantially proportional to the enlargement (spread) and reduction (contraction) of the space between the warp ends. Seamless and seamed tubes with variable diameters can be produced using the inventive method.
Abstract:
A vehicle safety system has a plurality of safety device controllers (200) for controlling safety devices such as airbag assemblies, seat belt tensioner assemblies, fuel cutoff switch assemblies, battery disconnect switch assemblies, assemblies for sending notification to emergency services, and assemblies for sending vehicle location data. The system accepts data from other vehicle systems such as speed data from the antilock brake system to distinguish between a low speed and a high speed crash, seat occupancy data to selectively activate airbags, and steering system and acceleration data to detect vehicle rollover conditions. The system provides for fault detection and notification to the vehicle operator, as well as immunity from electromagnetic interference through the use of distributed controllers that communicate with a central electronic control unit (300) over digital communication bus (500) using coded commands and data. Each controller has the capability of performing self-tests and communicating the results to the central electronic control unit.
