  • Seatbelt retractor
    Patent number: 8740125
    Abstract: A seatbelt retractor having a switching device with a gas generator and a switch housing having a gas generator housing portion for accommodating the gas generator and a gas flow path that communicates with the gas generator housing portion so that gas generated by the gas generator passes through the gas flow path. Further, the gas generator housing portion and the gas flow path are formed in the switch housing in a curved shape, and a die-cut hole extending in a direction of the gas flow path on an opposite side of the gas flow path to the gas generator housing portion is blocked from the gas flow path by the gas generator.

  • Seatbelt device
    Patent number: 8387907
    Abstract: A seat belt device is provided with a pin for connecting a spindle and a tread head in an initial state. The breaking load of the pin is varied depending on the direction of relative rotation between the tread head and the spindle, such that the pin breaks at a smaller load during operation of a pretensioner. As a result, this allows firmly fixing together the spindle and the lock member during ordinary use without adversely affecting usability, and, upon vehicle collision or the like, the EA load is not affected through breaking of the pin at the smaller load.
