A restraint system includes a housing defining a cavity tapering to an end and a plug disposed in the cavity. The plug is larger than the end of the housing. A seatbelt buckle is fixed relative to one of the housing and the plug and is moveable from a first position to a second position relative to the other of the housing and the plug. The plug is moveable relative to the housing toward the end during movement from the first position to the second position. One of the housing and the plug is plastically deformable by the other of the housing and the plug during movement from the first position to the second position.

An assembly includes a base and a seatbelt anchor. The seatbelt anchor has a first end defining a circular hole pivotally supported by the base and a second end fixed in position relative to the first end. The assembly includes a buckle fixed in position relative to the second end. The assembly includes a pyrotechnic actuator secured to the base. The assembly includes a connector extending from the pyrotechnic actuator to the seatbelt anchor.

A belt pretensioner has a base member. The base member has an axial cavity within. An actuating member is hollow and fits within the axial cavity of the base member. The hollow actuating member telescopically slides within the axial cavity and an initiator fits within the hollow portion of the actuating member. In a critical situation such as a crash, the initiator is triggered and the expanding gasses move the actuating member. The actuating member is connected to seat belt webbing and this movement provides the necessary pretensioning of the seatbelt. In some embodiments, a locking means is used to prevent the belt pretensioner from loosening once triggered. One embodiment is provided for use with a child seat. A transversely mounted belt pretensioner embedment is also disclosed.

A pretensioner and a seat belt device are provided. A pretensioner includes a wire connected to webbing that restrains an occupant, a piston disposed to the wire, a cylinder that slidably accommodates the piston, a gas generator that applies driving force to the piston, and a housing that integrally connects the cylinder and the gas generator. The housing includes an insertion hole that guides the wire, a communication part that is communicated with the cylinder and the insertion hole, and a gas-supply port that supplies gas generated by the gas generator to the communication part. The pretensioner includes a wire guide disposed at a boundary portion of the insertion hole and the communication part, and a holding member that is inserted into the communication part and locked to the gas-supply port, thereby to position the wire guide.

On a belt tensioner cable guide member (10) comprising a guide duct (42) for a cable of a belt tensioner and comprising a pressure duct (40) for fluid communication between an inflator and a pressure chamber to which a displacement body to be driven and being coupled to the cable is assigned, a first sealing element (44) sealing the guide duct (42) against the cable and especially enclosing the cable in the peripheral direction is provided within the guide duct (42).

A pre-tensioner for a safety belt of vehicles is provided. The pre-tensioner for a safety belt of a vehicle that is disposed in a side sill of the vehicle and that operates to pull the safety belt by pushing a piston into a tube by a high pressure gas of a gas generator using explosive power of gunpowder that is configured at one side of a bracket in a state in which the piston is connected to the safety belt through a wire within the tube including: internal and external weldnuts that are fixed to each one side of internal and external side surfaces of the side sill, wherein by penetrating the side sill in a vehicle width direction by forming a screw at an external circumference of both end portions of the tube, the both end portions are engaged with the internal and external weldnuts, respectively.

A vehicle seatbelt device that includes: a lap belt that restrains a waist portion of an occupant seated in a vehicle seat; a connection member that connects an end portion of the lap belt with an anchor provided at either a side of the vehicle seat or a location on a vehicle body; a retractor that is provided at a front side of a vehicle relative to the anchor, and that is actuated in a vehicle collision or in a case in which a vehicle collision has been predicted; and a load transmission member that is coupled with the connection member so as to be movable relative to the connection member, and that is retracted by the retractor in a case in which the retractor is actuated.

A seatback portion has a tether passageway defined therein from proximate an upper section to proximate a lower section thereof. A seatbelt tether includes a tensioning mechanism, a tether ring and a connecting portion that extends from the tether ring to the tensioning mechanism. The connecting portion extends through the tether passageway with the tether ring located at the upper section outside the seatback portion. The tether ring is shaped and dimension to slide-ably receive a seatbelt. The tensioning mechanism selectively applies tension to the tether ring. In a non-tensioned state the tether ring is movable to an upper outboard side of the seatback portion. In a tensioned state the tether ring is pulled toward a headrest supporting section of the seatback portion inboard and away from the upper outboard side of the seatback portion.

There is provided a vehicle seat belt system including: webbing that has one end anchored to one seat width direction side surface of a vehicle seat or to a vehicle body, and that restrains an occupant seated in the vehicle seat; a retractor to which another end of the webbing is engaged and that is configured to take up the webbing, the retractor being provided with a pretensioner which, when activated, pulls in the webbing; a buckle, with which a tongue plate attached to the webbing can be engaged; a force limiter that allows the buckle to move to thereby reduce a tensile load acting on the webbing due to activation of the pretensioner; and a warning section that is configured to utilize movement of the buckle resulting from the force limiter to notify the occupant of an abnormality that the force limiter has been activated.

A seatback portion has a tether passageway defined therein from proximate an upper section to proximate a lower section thereof. A seatbelt tether includes a tensioning mechanism, a tether ring and a connecting portion that extends from the tether ring to the tensioning mechanism. The connecting portion extends through the tether passageway with the tether ring located at the upper section outside the seatback portion. The tether ring is shaped and dimension to slide-ably receive a seatbelt. The tensioning mechanism selectively applies tension to the tether ring. In a non-tensioned state the tether ring is movable to an upper outboard side of the seatback portion. In a tensioned state the tether ring is pulled toward a headrest supporting section of the seatback portion inboard and away from the upper outboard side of the seatback portion.
