A passenger protection device may be configured with an airbag including a protection space portion region for alleviating restraint pressure at the time of restraining a passenger, so as to restrain the passenger, regardless of difference in physical build of the passenger on the vehicle seat at the time of expansion and inflation. A determination may be made regarding whether or not a directly seated object on the vehicle seat is a passenger or a child seat based on the tension information from a belt tension sensor. Depending on the outcome of the determination, performance of an airbag or an inflator may be controlled by a control device.

Passenger protection device

A safety restraint system for use in a vehicle. The system includes a safety restraint component coupled to a navigational module. The navigational module is adapted to determine a location of the vehicle. The component is adapted to be actuated in response to the determination. The safety restraint component may be a safety belt pretensioner. The component may be adapted to be actuated when the navigational module determines the vehicle has entered or is approaching a zone meeting a predefined criteria.

Navigation-based safety restraint system and method

An inflatable seat belt apparatus is formed of an inflatable portion which is usually maintained in a band shape and has an envelope part inflated and deployed in a spindle shape by introducing a gas generated by a gas generating device, the gas generating device acting in case of exceeding a predetermined threshold, a webbing having the inflatable portion extending over at least a range directly contacting with an occupant, a tongue fixed to an end of the inflatable portion and having a gas inlet from the gas generating device inside thereof and a buckle which detachably engages the tongue. The envelope part is made of a knitted fabric expanded in the weft direction in a range of contacting the chest of the occupant when the envelope part is inflated. The inflatable seat belt apparatus includes an inflation restricting device for restricting the expansion in the weft direction besides the range.

An air bag is structured by superposing a lower panel and an upper panel and sewing up the peripheral portions of the panels. The air bag is provided with an opening for an inflator at its rear portion. Flaps are extended from a peripheral portion of the opening for the inflator.

Air bag

The invention is a combination of an air bag device and a vehicle. An air bag for the air bag device for a passenger seat or a rear seat is structured by superposing a lower panel and an upper panel and sewing up the peripheral portions of the panels. The lower panel is longer than the upper panel. Portions of the lower panel are superposed each other and extended out of the air bag so as to form elongated portions. A protrusion of the air bag is formed by sewing up side edges of the elongated portions with threads.

Combination of an air bag device and a vehicle

An air bag for a passenger seat or a rear seat which is produced by easy sewing and is assembled into an air bag device easily is structured by superposing a lower panel and an upper panel and sewing up the peripheral portions of the panels. The lower panel is provided with an opening for an inflator and vent holes. The opening is provided with a cloth sewed on the outside of the periphery thereof. The rod-shaped inflator is inserted between the cloth and the opening. The both ends of the inflator are fixed to a casing.

An inflatable seat belt apparatus is formed of an inflatable portion which is usually maintained in a band shape and has an envelope part inflated and deployed in a spindle shape by introducing gas generated by a gas generating device, the gas generating device acting in case of exceeding a predetermined threshold, a webbing having the inflatable portion extending over at least a range directly contacting with an occupant, a tongue fixed to an end of the inflatable portion and having a gas path from the gas generating device and a buckle to which the tongue is detachably engaged. The inflatable portion has an elastic inflatable unit inserted into the envelope part and is inflated and deployed by introducing the gas generated by the gas generating device into the elastic inflatable unit via a filter.

An inflatable seat belt apparatus is formed of an inflatable portion which is usually maintained in a band shape and has an envelope shaped elastic inflatable member inflated and deployed in a rough spindle shape by introducing gas generated by a first gas generating device. The gas generating device operates in case of exceeding a predetermined threshold. A webbing includes the inflatable portion and extends over at least a range directly contacting with an occupant. A tongue is fixed to an end of the inflatable portion and includes a gas path extending from the gas generating device. A buckle is detachably engaged with the tongue. The envelope shaped inflatable member is inflated in a predetermined shape by introducing gas for a leak testing from a second gas generating device when the tongue is engaged with the buckle, and is inspected whether or not the gas leaks by a gas leak detecting device disposed in the gas path. A state of the damage is inspected.

An inflatable seatbelt system wherein if extremely high acceleration acts on the vehicle laterally when a lateral collision or other similar emergency situation occurs and this acceleration exceeds a first set value, a gas generator is activated to inflate a shoulder belt (2) surely and almost instantaneously in the same way as in a case where extremely high deceleration acts on the vehicle longitudinally. In this case, a portion of the shoulder belt (2a) extending between first and second anchors (6) and (20) also inflates to a large extent. Accordingly, the head and face of the occupant (M) are brought into contact with the inflated shoulder belt portion (2a) by the lateral acceleration. Therefore, the heavy impact load, which would otherwise be applied to the occupant's head and face, is relieved. Thus, the occupant's head and face are effectively and reliably protected.

Inflatable seatbelt system

An inflatable seatbelt system having a webbing (11) formed by laying two strap-like webbing base fabrics (11a) and (11b) one on top of the other, which have a predetermined width approximately equal to the width of a typical conventional seatbelt, and sewing the respective side edges of these webbing base fabrics to each other at both lateral ends of the webbing (11). The warp (14) is disposed parallel to the longitudinal direction of the webbing (11), and the weft (15) is disposed perpendicularly to the longitudinal direction of the webbing (11). The warp (14) is formed of threads which do not practically stretch when the webbing (11) inflates. The weft (15) is formed of rubber-like stretchable threads made of an elastic material, e.g., urethane. Accordingly, the webbing (11) inflates to a large extent in the lateral direction, but it does not practically inflate in the longitudinal direction.

An inflatable seatbelt system having a webbing (11) formed in the shape of a bag from a woven fabric. The warp of the webbing (11) is disposed in the longitudinal direction of the seatbelt, and the weft is disposed in the lateral direction of the seatbelt. The weft is formed of spandex threads made of a material having a relatively low modulus of elasticity and stretchable in a rubber-like manner, e.g., urethane. The weft (15) on the reverse side of a portion of the webbing (11) corresponding to the boundary between a shoulder belt (2) and a lap belt (3) is cut over a predetermined area. A gas outlet portion (5e) of a tongue (5) is inserted into the shoulder belt (2) from an opening 11(c) formed by widening the cut area of the weft (15). The lap belt (3) of the webbing (11), which extends in the opposite direction to the direction of insertion of the gas outlet portion (5e), is passed through a webbing receiving hole (5b) provided in an operating portion (5c) of the tongue (5) by slightly contracting the lap belt 3 in the direction of the width thereof. A belt cap (16) is fitted onto the gas outlet portion (5e) of the tongue (5) with the webbing (11) interposed therebetween, thereby securing the tongue (5) to the webbing (11).
